Abstract: A speed control system for sorters (e.g. sliding shoe sorters) comprises a sensor for measuring a sorter current speed of a sorter and a speed controller for setting peripheral conveyor commanded speeds for peripheral conveyors in communication with the sorter. During acceleration or deceleration of the sorter (e.g., in response to start or stop events of the sorter, or from one operating speed to another operating speed), the speed controller sets the peripheral conveyor commanded speeds to match or track the sorter current speed in order to ramp up or ramp down speeds of the peripheral conveyors with that of the sorter, which accelerates or decelerates more slowly than the peripheral conveyors. The speed controller may control the speed of different types of peripheral conveyors (e.g., upstream, intermediate, downstream) in various ways based on the type of the peripheral conveyors and/or based on user-configurable exception settings.

Abstract: The present invention relates to using a self calibrating and recalibrating 230, 925 optical sensors piston rod displacement. Self calibration enables field calibration of uncalibrated 230, 925 optical sensors. During operation, recalibration enables detecting and correcting for wear and damage of the 200 piston rod and/or 230, 925 optical sensors. 210 Calibration positions on the surface of the 200 piston rod are imaged by 230 optical sensors using laser or darkfield lenses designed for optical computer mice. Natural surface patterns can be used in locations where 210 calibration positions are required, which reduces or eliminates the need for marked 210 calibration positions. Marked 210 calibration positions are spatially unique encoded sequences used to determine the piston rod absolute position. Storing only the significant features of 210 calibration positions saves significant memory.

Abstract: A user, such as an employee of an institution, may travel overseas where data or devices may be compromised. Described herein is a system and method for receiving travel data for the user from a travel data source and receiving a list of countries with a high level of security threats where data security may be an issue. Based on the travel data for the user and the list of countries with a high level of security threats, it may be determined whether the user is entering a country with a high level of security threats. If so, one or more user devices associated with the user may be determined, and data security scans of the devices may be generated before, during, and/or after travel. Data security issues may be determined based on a comparison of the scans. A report of the issues may optionally be generated.

The longitudinal channels are in fluid communication with a plurality of flow control gates, such that a first number of flow control gates are in fluid communication with a first longitudinal channel and a second number of flow control gates are in fluid communication with a second longitudinal channel. The first number of flow control gates may define a crest height that is lower, along a vertical direction, than a crest height defined by the second number of flow control gates. The flow control gates may define a crest length proximate a crest of the flow control gate and a nappe length defined proximate a first height above the crest. The nappe length may be greater than the crest length. The aerator may have a plurality of low head baffles.

Abstract: A lighting device can include a substrate, two or more light-emitting elements formed over the substrate, an affixing layer fixing the two or more light-emitting elements in place, and a transparent conductive layer in electrical contact with the light-emitting elements. The substrate and the transparent conductive layer sandwich the affixing layer with the light-emitting elements in place. The affixing layer is an electrically insulating material. The affixing layer is doped with a photo active or photochromic material. In a first mode when the light-emitting elements are energized, the photo active or photochromic material of the affixing layer is excited by the light-emitting elements. In a second mode when the light-emitting elements are de-energized, the affixing layer produces a persistent luminescence.

Abstract: Described is a belt used in conjunction with road wheels device and method of supporting weight of hybrid tire tracking-laying vehicles more safely and efficiently at highway speeds. The supporting device includes belts 004, road tires 002, track tires 003, tensioning tires 015, and supporting frame and axles. The road tires 002 are located outside beside the belt 004 with a larger diameter than the belt 004. The outside road tires work to laterally guide the belt 004 and to prevent the rubber belt 004 from track-throwing. The tensioning tires 015 running inside the belt 004 along the wheel runways 027, are guided by the belt guide horns 020. In this proposed device, the belt 004 can remain sufficiently taut to prevent the guide horns 020 from slipping over the track tires 003 and road tires 002. The designed hybrid belt with tires can remove debris such as mud and sand, and prevent track-throwing even during turning maneuvers.

Abstract: A fluid linkage allows for coordinated movement of mechanical components separated by a distance. In applications where accurate coordination is required, a mechanism called a limit-switch valve (180) is activated at specific actuator positions. The limit-switch valves are able to detect fluid loss in the fluid linkage between the actuators and compensate for this fluid loss. A volume displacement servomechanism is created by connecting pressure actuators (360, 361) of a fluid control valve (120) to a control actuator (133). A basic position feedback servomechanism is created by connecting pressure actuators (362, 363) of a fluid control valve (150) to a control actuator (135) and a feedback actuator (145). The fluid control valve (150) controls the servomotor actuator (146) to which the feedback actuator (145) is attached. A position tactile feedback servomechanism allows an operator to perceive the load on the servomotor actuator (146) by its reflection on the control actuator (135).
