Abstract: A steer-by-wire control system adapted for use with a material handling vehicle such as a forklift includes a controller programmed to receive input indicative of a desired direction of travel of the material handling vehicle and to control an actuator coupled with the steered wheels of the material handling vehicle to change the direction of travel of the vehicle and synchronize the direction of travel with a position of a steering wheel of the material handling vehicle.

Abstract: A system for controlling a turbine valve is provided. The system includes a hydraulic pilot valve section being moveable in a first direction and a second direction; a main hydraulic valve section being moveable in a first direction to close the turbine valve and a second direction to open the turbine valve; a position demand indicating a desired position of the turbine valve; a first feedback indicating an actual position of the hydraulic pilot valve section; and aa second feedback indicating an actual position of the main hydraulic valve section. The system also includes a pilot valve error; a main valve error; a turbine valve error; and a pilot valve adjustment moving the hydraulic pilot valve section in response to the turbine valve error. The turbine valve error is repeatedly determined and the pilot valve adjustment repeatedly moves the hydraulic pilot valve section to minimize the turbine valve error.

Abstract: A standoff chemical detection system that includes a source and detector are provided. The source includes: a controller, memory communicatively connected to the controller, optical sources each constructed to operate over different wavelength ranges, and a power supply. The controller controls the plurality of optical sources to emit respective infrared beams towards a target detection area in a sequential order. The detector includes: an image sensor and a controller that is communicatively connected to the image sensor. Memory and the notification device are also communicatively connected to the controller. The image sensor receives attenuated infrared beams emitted by the optical sources sequentially and at least partially attenuated by chemicals in the target detection area. The controller is constructed to calculate stimulus value signals from the recorded image data and determine whether a hazard chemical is located within the target detection area based on the calculated stimulus value signals.

Abstract: A chemical-detecting apparatus includes an array of sensors. Each sensor of the array of sensors is oriented skyward in operation. Each sensor includes a chemical receiver including a plurality of infrared color vision filters cooperating to detect a plurality of infrared color vision signatures. The plurality of infrared color vision signatures respectively correspond to a plurality of chemicals.

Abstract: Methods and apparatuses for detecting cancerous tissue are provided. A target area comprising suspected tissue is illuminated with infrared light. Reflected light from the target area is received and filtered by a plurality of infrared optical filters with overlapping pass-bands. The filtered reflected light from each of the plurality of optical infrared filters is directed onto at least one optical sensor, and data generated by the at least one optical sensor and corresponding to the filtered reflected light from each of the plurality of optical infrared filters is provided to a controller. The controller calculates a vector corresponding to the target area from the data, and compares that vector to a plurality of vectors respectively corresponding to different types of cancerous tissue. The controller determines based on a result of the comparison whether the target area includes at least one type of cancerous tissue.
