Abstract: A method is provided for Bluetooth Low Energy (BLE) communication between a remote control device comprising a peripheral BLE device and a controller on a materials handling vehicle comprising a central BLE device. The method comprises: polling via a plurality of connection requests, by the central BLE device, communicated with the peripheral BLE device with which the central BLE device is paired. The peripheral BLE device comprising one or more activatable switches. Based on the status of the one or more activatable switches, the peripheral BLE device sending reply messages to at least a portion of the plurality of connection requests in accordance with at least one of a first or a second communication operating mode. When operating in the first communication operating mode, the peripheral BLE device replies to only a portion of the plurality of connection requests, wherein each reply message is indicative of the status of the one or more activatable switches.

Abstract: According to the embodiments described herein, system and methods for determining relative pose of materials handling vehicles in an industrial environment may include utilizing UWB antenna array systems respective mounted on the materials handling vehicles to send mutually received information to determine the relative pose between the vehicles, determining one or more fields of each materials handling vehicle, and determining one or more overlapping fields between the materials handling vehicles based on the determined one or more fields and the relative pose. A vehicle control may be implemented based on the determined relative pose and the overlapping fields as a field enforcement, such as a control action to avoid collision between the vehicles.

Abstract: Techniques are disclosed for reducing the time required to read and write data to memory. Data reads and/or writes can be delayed when error correction code (ECC) bits, which are used to detect and/or correct data corruption, are written to memory. Writing ECC bits can take longer in some instances than writing data bits because an ECC write may involve a read/modify/write operation, as opposed to just simply writing the bits to memory. Some latencies associated with writing ECC bits can be hidden by interleaving ECC writes with data writes. However, if insufficient data writes are available for interleaving, hiding such latencies become difficult. Thus, various techniques are disclosed, for example, where ECC writes are deferred until a sufficient number of data writes become available for interleaving. By interleaving ECC writes, the disclosed techniques decrease the overall time required to read and write data to memory.

Abstract: A chainable Power over Ethernet Node (CPEN) is provided according to the invention. The CPEN contains an electronic circuit and control method to pass power, communications, or both power and communications to subsequent chainable nodes or other devices. The invention allows one cable run to serve a plurality of chainable nodes thus greatly reducing the amount of cable required. The invention enables redundant connections in both power and communications to network nodes to prevent failure in case of cable or node fault. The chainable node has 2 or more ports, all of which are interchangeable. Any port can respond to PoE Powered Device (PD) classification and receive power. Any port can act as a Power Supplying Equipment (PSE) to enable power to subsequent nodes. The ports can support standards compliant PoE detection, classification, and operation, and can support non-standard variations.

Abstract: A system is provided for use in an industrial loading dock wherein the location of an industrial vehicle is detected and tracked in real-time, and one or more safety zones are created such that a computer or microcontroller triggers a response in the industrial vehicle upon the vehicle's entry into each such zone. The system includes a plurality of anchor radio transceivers positioned in proximity to a workspace. Each anchor radio transceiver is positioned in a known location such that the plurality of anchor radio transceivers form a fixed array of anchor radio transceivers. At least one mobile radio transceiver associated with a mobile industrial vehicle is also provided. The mobile radio transceiver is configured to exchange data packets of information with one or more of the plurality of anchor radio transceivers. A computer is provided that is in communication with the fixed array of radio transceivers.

The switching shaft has a transversely running cutout for mounting the rotary contact link, which protrudes on both sides out of the switching shaft. The rotary contact link is connected, via at least one spring element, to the switching shaft for applying a contact force in the closed position and for the rotary contact link to remain in the open position.

Abstract: The electric trim saw is unique because of the way it cuts. The electric motor is mounted on a two way slide, the slides allow the saw to follow the exact contour of any piece of trim (Baseboard, Chair rail Etc.) the guide tip has a fine point with a tiny ball bearing kind of like a ball point pen. This tip is on the same plane as the cutting bit therefore the bit cuts the board on the base plate with the exact same contour as the scrap piece in the clamp. The clamp holds the scrap piece in line and in place while the cuts are being made.
