Abstract: A motor controller executes an axis module for each of multiple motors coupled to a shared load. A first control module passes at least one state variable to a second control module without experiencing communication delays between the axis modules. In order to decouple interaction between axes, the first control module determines the desired state variable at a periodic update rate and stores the desired state variable in memory. The first control module provides an indication to the second control module that the desired state variable is available. Within the same period at which the desired state variable is determined, the second control module receives the indication that the desired state variable is available and reads the state variable from the memory of the controller. The second control module executes using the desired state variable to reduce coupling between the two control modules.

Abstract: A bow sight mounting system including a forward sight assembly used with conjunction with a rearward sight assembly adjustably mounted to a base plate, each component considered modular. The forward sight assembly, interchangeable with identical parts in the rearward sight assembly, includes two pin sight assemblies, two sight mounting brackets and two moveable connecting bars terminating in a base mounting plate. The base mounting plate is symmetrical with the ability to mount on a left-hand or right-hand bow. The moveable connecting bars extends perpendicular to the bow frame and base mounting plate and locates the sight mounting bracket in position to be inline with the bowstring. The forward pin sight assembly containing a vertical pin works with conjunction with the rearward pin sight assembly containing two vertical pins. The rearward vertical pins are positioned as such to create an open gap alignable with the forward pin and the target.

Abstract: A dock seal, such as a header, side seal or draft pad mounted alongside a doorway of a loading dock, comprises a compressible foam core that includes a plurality of slits of insignificant thickness, wherein the slits can be strategically arranged and sized to adjust the seal's compression characteristics at different areas of the seal. In some cases, the slits extend only partially into the foam core so that the core remains intact as a unitary piece.

Abstract: A loading dock shelter having a resilient and flexible seal assembly is provided for forming a substantially air-tight seal between the dock opening and the truck. The seal assembly comprises a support or panel member which is adapted to attach to the loading dock frame and to support a seal member. The seal member has a substantially hook-shaped cross-section adapted to hookably engage the incoming truck and is capable of resiliently flexing between a hook-shaped cross-section in the disengaged position and a substantially straight cross-section in the sealing position in response to the truck. The hook-shaped cross section permits the seal member to sealably engage the interior wall of the truck, and, in the alternative, will seal against the peripheral edge of the truck, or the exterior wall of the truck depending on the size and position of the truck.

Abstract: A centering device and method includes a sensor for sensing the center of a bore preformed in a workpiece, and a remote output unit for outputting the positional signal generated by the sensor. The sensor in held within a spindle of a machine tool and includes a stylus which contacts the inner surface of the bore, a local oscillator and modulator and an RF oscillator and antenna. The stylus oscillates a linear proximity sensor. The proximity sensor outputs a proportional DC voltage which is input to a voltage controlled oscillator (VCO) which outputs a square-wave with a frequency which is a function of the stylus position. The RF oscillator and antenna includes a radio transmitter and antenna and receives the square-wave output of the VCO, converts the square-wave to a modulated RF signal and transmits the modulated RF signal to the remote output unit. The remote output unit includes an RF receiver and demodulator, and a signal processor and output and display.

Abstract: A vehicle anti-theft system for an automotive vehicle positions the driver seat of the vehicle in an undriveable position. The system includes a seat having a seat back and a seat base both of which have a fore and aft position. A first motor is operatively coupled to the seat back for moving the seat back between the fore and aft position. A second motor is operatively coupled to the seat base for moving the seat base between the fore and aft position. An input device generates an activation signal. A controller is connected to the first motor, the second motor, the input device and a power source. The controller upon receiving the activation signal connects the power source to the first motor and second motor whereby the first motor moves the seat back to the fore position and the second motor moves the seat base to the fore position.
