Business Segments Description

The Company’s principal product line for this segment is the Schmitt Dynamic Balance System (SBS), which consists of a vibration sensor, a computer control unit, and a balance head that is placed either externally on the grinding wheel spindle with the use of a spindle mounted adaptor or internally inside the spindle bore. The SB-5500 control panel contains up to four slots for additional circuit boards designed for specific functions, such as manual balancing, balancing using hydro chambers and process monitoring, which involves the detection and analysis of high frequency noise, known as acoustic emission (AE), generated by the grinding process. SBS products are designed as economical yet highly precise measurement and control devices for permanent or portable installation on grinding machines that can detect and correct imbalance caused by vibration as small as 0.02 microns. Customers can also detect and analyze the AE signal generated during grinding or wheel dressing to help monitor and improve the grinding process. Customers include both end user operators as well as manufacturers of grinding machines worldwide for a wide variety of industries that utilize the grinding process, including the automotive, industrial, aerospace, and medical industries where specifications and operating tolerances on machined parts are increasingly precise.

The SB-5500 is fully automated, eliminating the need to pre-balance parts such as grinding wheels. This reduces machine setup time and ensures a smoother and more efficient grinding process. Operating on a principle of mass compensation for wheel imbalance, the balance head contains two movable eccentric weights, each driven by electric motors through a precision gear train. These weights are repositioned to offset any imbalance in a grinding wheel or other application. Imbalance or vibration is picked up by the vibration sensor that feeds the detected signal to the control unit, which filters the signal by revolutions per minute. The controller then automatically drives the balance head weights in a direction that reduces the amplitude of the vibration signal. The balance cycle is complete when the weights are positioned to achieve the lowest vibration level, as low as 0.02 microns.

The SB-5500 also includes an optional Acoustic Emission Monitoring System (AEMS) control card, which uses proprietary acoustic sensor technology to monitor the AE signal generated on the grinding machine during key events in the grinding process. The AEMS card allows rapid, automatic grinding wheel in-feed, right up to the point of initial contact of the grinding wheel with a new part loaded in the machine. The system can automatically detect the initial contact and very quickly report this event to the machine control, stopping the wheel in-feed without operator intervention. Part crash occurs when a part or fixture is incorrectly loaded into a grinding machine or some abnormal condition occurs. Rapid in-feed of the wheel may then result in a dangerous or expensive crash. The AEMS card allows the grinding machine’s operating system (known as a computer numeric control or CNC system) on the machine to monitor the acoustic levels and detect any unexpected contact when it happens. The system then reports that abnormal contact and instructs the CNC program to stop the grinding process, usually within one millisecond.

The SB-5500 also offers two process control cards that fit inside the control panel to provide enhanced control of the grinding process: the ExactControl™ card and the ExactDress™ card. The ExactControl process control card offers multi-functional grinding process control capability by detecting and analyzing either the AE signal pattern or the machine power fluctuations and then using one of seven process control strategies to adjust and optimize the grinding process based on that signal data, resulting in improved part quality and reduced operating costs. Software control strategies include ExactDisplayTM (graphically displays the measurement signal), ExactGap (displays and evaluates the measurement signal against a predetermined signal threshold to automatically determine when the grinding wheel touches the work piece and to shorten the time between grinding work pieces), ExactTimeTM (displays and evaluates the time interval of a measurement signal that is above a predetermined signal threshold to monitor the minimum or maximum processing time, ExactIntegralTM (displays and evaluates the area under a measurement signal curve to optimize the grinding process for the particular work piece), and ExactDressTM (displays and evaluates the measurement signal and compares it to a standard threshold to optimize the grinding wheel dress process).

The ExactDress control strategy is also available in a separate process control card as part of the AEMS system to automatically monitor and control the grinding wheel dressing process. The AE signal pattern of a wheel dress is displayed and compared to a stored “master” AE signal pattern and indicates when the dressing process has been successfully completed. Monitoring for AE levels during wheel dressing permits the operator or CNC control to determine if the wheel is being dressed fully across its width, control the aggressiveness of the process and maintain the quality of the dressed wheel to conserve wheel material.

Additional SBS products include the SB-2000 and the AE-1000. The SB-2000 is an easy-to-use, compact manual balancing system offering both one and two plane manual balancing capabilities. The system comes in a dedicated machine installation version (SB-2000) and a portable version (SB-2000-P). Each version of the system displays up to four digits of resolution for vibration and six digits for RPM readings and supports a spindle speed range of 30 to 100,000 RPM. The portable SB-2000-P version attaches magnetically to any location on the machine for easy setup and use. The AE-1000 is a dedicated AE control platform that reduces air machine grinding time and alerts the operator to potential grinding wheel crash conditions by using proprietary AE detection technology to monitor the high frequency signals generated by the grinding process.

Notable features of the SBS system include its ability to fit almost all grinding machines, ease of installation, compact and modular construction, ability to balance a wheel while on a machine, virtual elimination of wheel vibration, automatic monitoring of balancing, display in a variety of languages and in metric units of measurement, instrument grade calibration, short balance process, measurement of both displacement and/or velocity and minimal operator maintenance. The SB-5500 also offers the capability of fully integrating its operation and output within any grinding machine’s CNC operating system by the use of its IVIS (Intelligent Visualization) software.
Benefits of using the SBS system include improved quality of finished parts, elimination of grinding gap time in the grind cycle resulting in increased efficiency and part throughput, ease of product adaptation, monitoring and correction of part crash, minimal downtime, complete and ready installation, elimination of static balancing, longer life of the grinding wheel, diamond dressings and spindle bearings, the ability to balance within 0.02 microns and its adaptability to all types of machines.

Precision grinding is necessary in major manufacturing areas including the automotive industry (gear trains, camshafts, crankshafts, valves), bearings (roller and tapered types), ceramics (precision shaping), electric motors (shafts), pumps (shafts and turbines), aircraft (engine parts such as turbine blades), and general manufacturing. Precision grinding has an established worldwide presence in all industrialized countries and is expanding as a method of material removal and part processing.

Within the Measurement Segment, the Company designs, manufactures and sells laser and white light sensors for distance, dimensional and area measurement for a wide variety of commercial applications, laser-based microroughness measurement products for the semiconductor wafer and hard disk drive industries and for other industrial applications, laser-based surface analysis and measurement products for a variety of scientific applications, and ultrasonic measurement products that accurately measure the fill levels of tanks holding propane, diesel and other tank-based liquids and transmit that data via satellite to a secure web site for display.

Laser and White Light Sensors

These products include lasers utilizing both triangulation and time-of-flight methods of measurement, and confocal chromatic white light sensors that are used in a wide range of industrial applications including manufacturing, lumber production, steel casting, glass and paper production, medical imaging, crane control and micron-level part and surface inspection and are sold under the Acuity brand. Presently, there are 12 products offered under the Acuity brand: The AccuRange (AR)1000, AR2000, AR2500 and AR3000 distance measurement sensors, the AR700, AR500 and AR200 series of triangulating laser displacement sensors, the AR CCS Prima and the AR CCS Initial chromatic confocal sensors, the AccuProfile (AP) 400 and AP820 and the Aquity (AQ) 6 2D laser line scanners. The Company designs, manufactures and sells the AR200 and AR700 and distributes the AR500, AR1000, AR2000, AR2500, AR3000, AR CCS Prima, AR CCS Initial, AP400, AP820 and the AQ6, primarily into North America.

The AR1000, AR2000, AR2500 and AR3000 distance measurement lasers utilize pulsed time of flight measurement principles to accurately measure distances of up to 30 meters (up to 300 meters with retro-reflective tape) with the AR1000, up to 100 meters (500 meters with retro-reflective tape) with the AR2000, up to 50 meters (500 meters with retro-reflective tape) with the AR2500 and up to 300 meters (3000 meters with retro-reflective tape) with the AR3000. These products are highly versatile, being able to measure distances both indoors and outdoors. Applications include, but are not limited to, load confirmation, alignment, lumber positioning, crane monitoring, fill level measurement, velocity measurement and laser altimeter.

The AR700 is a triangulation laser displacement sensor that provides superior performance in terms of accuracy, repeatability, and sample speed. The AR700 boasts output speeds up to 9400 Hz and resolutions as a micron. The laser will output 9400 distance readings in a single second. The unit is also very compact, measuring approximately 80% smaller than its predecessor, the AR600. Model variations permit applications up to 50 inches in range. Applications include high speed road profiling, product dimensional or thickness measurement, rubber thickness measurement, lumber or plywood thickness measurement, carton dimensioning and product positioning.

The AR500 is a compact triangulation laser displacement sensor that provides accurate measurements (+/- 0.15% linearity) at high speeds (standard to 9400 Hz, high speed option up to 56K Hz). The same compact enclosure houses models with ranges from 5 to 1000 millimeters. Sensor options include blue laser diodes, faster speeds and cooling jackets. Applications include radiating surfaces and high speed applications such as road texture, ballistics and high speed event monitoring.
The AR200 line is the Company’s most compact series of triangulating laser displacement sensors. Five models cover metric measurement ranges from 6 to 100 millimeters. All models boast a 1/500 accuracy rating for measurements within twelve microns. All models are standard with analog, limit switch and serial outputs. The AR200 sensors, much like the longer-range AR700 sensors, project a beam of visible laser light that creates a spot on the target surface. Reflected light from the surface is viewed from an angle by a line scan camera and the target’s distance is computed from the image pixel data. The AR200-6M, -12M, -25M, -50M, and -100M have ranges in millimeters that match their model number. The AR200 displacement sensor cannot be overloaded and measures accurately even when a mirror reflects the entire light beam back to the detector.

The AR CCS Prima white light confocal-chromatic displacement sensor is the most precise measurement system from Acuity. Using a novel optical principle of measuring the reflected light’s component wavelengths, these confocal sensors measure distance and position to within nanometers. These compact probes can measure to opaque, shiny or even transparent surfaces. Unlike the other Acuity distance sensors, the Prima Confocal systems are comprised of an optical measurement “pen” and a separate controller. This controller houses all of the electronics, light source, etc. Only emitted white light and reflected signals are passed between the pen and the controller via a thin fiber-optic transmission cable. The Confocal-Chromatic Sensors (CCS) are offered in a variety of measurement ranges and standoff distances, each with a corresponding resolution. The shortest-range models resolve to 5 nanometers of height change.

The AR CCS Initial confocal sensor is an extremely precise point sensor for measuring displacement and thickness. Each system includes a controller unit, a fiber optic cable, a measuring probe and all necessary cables and software. The CCS Initial measures distance and topography of varied targets, including silicon, polished metals, glass, contoured lenses, polymers, semiconductor masks and natural materials. The technology in the CCS Initial supports nanometer-scale resolutions and the system comes in five different measurement models that range from 0.4 to 12.0 mm.

The AP400 series line sensors are entry-level two-dimensional CMOS digital sensors for industrial surface dimensioning and measurement applications. The scanner quickly and accurately generates low noise 2D profile scans of objects, surface or scenes. The sensor has an onboard processor and memory and comes with AcuityView image analysis software. Typical applications include weld gap tracking and weld bead profiling, positional control of objects and surfaces, tire profiling, wheel profiling, surface profiling, 3D profile generation and dimensional measurement.

The AP820 is a two-dimensional laser line scanner that measures surface height profiles by projecting a beam of visible laser light that creates a line on a targeted surface. The AP820 is a highly accurate sensor for industrial surface dimensional and measurement applications. The scanner quickly and accurately generates low-noise 2D or 3D profile scans of objects, surfaces or scenes. The sensor automatically adjusts laser power and detector exposure to compensate for varying surface conditions. Typical scanner applications include weld gap tracking and weld bead profiling, positional control of objects and surfaces, tire profiling, wheel profiling, surface profiling, 3D profile generation and dimensional measurement.

The new AQ6 laser line sensor offers higher speed and higher resolution, with models from 0.3 megapixels to over 12 megapixels. The AQ6 uses the latest in new high density CMOS camera design with new Gigabit Ethernet communications and the newly released GeniCam high speed vision protocols. This allows the customer to increase the resolution on the target and reduce the amount of sensors needed for larger parts. The new outputs also will allow for a faster and less expensive integration of the sensor into the customer’s application. Applications include pipe and tube manufacturers, large laser line applications for flaw detection and high accuracy scans of difficult targets. The AQ6 also lends itself to custom OEM applications with laser lines of over 80 inches in length. Currently there are nine AQ6 models available.

Surface Roughness Measurement Products
These products use a patented technology using laser light scatterometry to perform rapid, accurate, repeatable, non-destructive and non-contact surface measurement tests that quantify surface micro-roughness. The technology is extremely precise, measuring surface roughness at the molecular (sub-Angstrom) level. Products are sold to manufacturers of hard disk drives, semiconductors, silicon wafers and optical products and industries involved in fabrication processes that require precise and reliable measurements.

Computer hard disk drives require exact manufacturing control and a narrow tolerance band for acceptable roughness, with surface roughness outside that narrow band resulting in a reduction in data density or storage capacity. The Company’s technology simultaneously measures disk surface roughness in two directions, radially, when the read/write head is moving to another disk sector, and circumferentially, when the read/write head is processing information on the disk. The two separate roughness levels are required for proper head operation. The Company believes the precise measurement methods provided by its products are not possible through any other cost-effective measurement means.

The Company’s product for the disk industry is the TMS (Texture Measurement System) 2000-RC, an accurate non-contact texture measurement system. The product (used on aluminum substrates) is currently used worldwide by most major disk drive manufacturers, providing fast, accurate and repeatable microroughness measurements while quadrupling production throughput when compared to other testing devices. Surface roughness can be measured to levels below 0.5 Angstroms. An Angstrom (Å) is a unit of measure equal to 1 hundred-millionth of a centimeter (the point of a needle is one million Å in diameter).

Remote Tank Monitoring Products
The Company’s Xact Tank Monitoring System provides remote fill level monitoring of propane, diesel and other tank-based liquids for tanks, large or small, anywhere in the world. Accessing accurate fill level information is essential to effectively manage inventory, improve delivery efficiency, reduce operating costs and increase profitability, and justify capital expenditures. The Xact system utilizes an ultrasonic sensor that is applied externally to the tank to calculate the fill level inside the tank with great accuracy (+/- 2% for large tanks, +/-1% for small tanks). The Xact system can also be installed to measure the fill levels of bobtail and transport trucks. For smaller tanks that are difficult to access or where the precise accuracy provided by the ultrasonic sensor is not as important, Xact also offers a sensor that is affixed to the dial of a preinstalled float gauge (known as a “gauge reader”) which detects the fill level that is reported by the gauge. Float gauges have a typical accuracy of +/- 8% to 12%. Tank fill data is then transmitted via the Globalstar® satellite network to a secure website for display. There is no reliance on phone land lines or cellular networks and therefore no dropped data. The use of satellite telemetry permits monitoring of any tank anywhere in the world. With the Xact system, minimum or maximum alarm or fill levels can be set to automatically notify operators by email anytime a particular tank reading exceeds thresholds or needs refilling. The Xact system can be used to monitor tanks as small as 125 gallons (473 liters) and as large as 90,000 gallons (340,686 liters). With Xact, operators can obtain timely and accurate readings of inventory levels and tank refill requirements instantly.

There are three main components to the Xact Tank Monitoring System:

Tank Sensor
The Xact ultrasonic sensor incorporates patented technology and is externally mounted to the bottom of the tank. The sensor produces a small electrical pulse, or a “ping,” that travels through the tank’s steel shell, which is reflected off the bottom surface of the liquid stored in the tank in the form of an echo that is detected by the sensor. The time of flight between the “ping” and the echo, which is measured in milliseconds, is then calculated to determine, based upon additional data regarding tank size and shape, the volume of liquid the tank contains. This information is then remotely transmitted via a satellite radio transmitter. For smaller tanks that are difficult to access or where the precise accuracy provided by the ultrasonic sensor is not as important, Xact also offers a sensor that is affixed to the dial of a preinstalled float gauge (known as a “gauge reader”).The gauge reader detects the fill level that is reported by the gauge and transmits that data by satellite in the same manner as the ultrasonic sensor. Float gauges have a typical accuracy range of +/- 8% to 12%.

Satellite Radio Transmitter
The Xact radio transmitter is placed on the top of the tank and is connected by cable to the tank sensor or gauge reader. The satellite transmitter transmits the tank data using the GlobalStar® satellite network to a GlobalStar® ground station and then to the Xact secure website where the tank data is displayed or is automatically directed to a customer’s automated inventory or delivery management system.

Xact Website
The Xact website is a secured location providing controlled access to the tank data for each customer’s various tank locations. The tank fill level data and geometry of the tank are used to calculate and display the precise fill level at predetermined measurement times along with additional information such as temperature, battery status, GPS coordinates and map location, fill levels that trigger email notification and the list of email recipients. In addition to the data being displayed on the website, the data can also be automatically directed to a customer’s automated inventory or delivery management system for full automation of the delivery process. Operators can now obtain highly accurate readings and tank information from even the most remote tanks conveniently and cost-effectively using their desktop computer, laptop, tablet or smart phone.


Similar to the Balancer Segment, the Measurement Segment uses a variety of methods to market and sell its products. First, sales and marketing managers direct the overall worldwide marketing efforts for surface measurement, laser and white light sensor and remote tank monitoring products. Second, both a marketing manager and a sales manager direct the overall worldwide marketing and sales efforts for distance measurement and dimensional sizing products. Third, the Company uses distributors for international markets for the promotion and sale of surface measurement products in China, Taiwan, Japan and Korea. The Xact product line utilizes two business development personnel, in addition to distributors for selected markets. All Measurement Segment products are assembled in the Portland, Oregon facility and shipped worldwide directly to customers.
