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: A method is provided for wireless communication between a wireless remote control device comprising a peripheral device and a controller on a materials handling vehicle comprising a central device. The method may comprise: polling via a plurality of connection event requests, by the central device, communicated with the peripheral device with which the central device is paired, the peripheral device comprising one or more activatable switches. Based on the status of one or more activatable switches, the peripheral device sending reply messages to at least a portion of the plurality of connection requests in accordance with at least one communication operating mode of the peripheral device, wherein each reply message is indicative of the status of the one or more activatable switches. Calculating, by the central device, a number of missed messages.

Abstract: Testing operational characteristics of a remote control device associated with a materials handling vehicle can include waiting for receipt of a first input indicative that a first button of the remote control device has been pressed, wherein the first button comprises a travel button of the remote control device. The testing may further comprise waiting for receipt, subsequent to receiving the first input, of a second input indicative that at least a second button of the remote control device has been pressed, wherein the second button relates to a first auxiliary vehicle function. The testing still further comprises determining whether or not a predetermined button pressing sequence is successful based at least in part on receiving or not receiving the first and second inputs; and optionally driving a display on the vehicle to provide a visual indication that the button pressing sequence is successful or not successful based on the determination.

Abstract: Using integrated circuits, such as field programmable gate arrays, it is possible to transfer data to common off the shelf storage devices at high speeds which would normally be associated with special purpose hardware created for a particular application. Such high speed storage can include prefetching data to be stored from a memory element into a cache, and translating the commands which will be used in accomplishing the transfer into a standard format, such as peripheral component interconnect express.

Abstract: The embodiment of the invention disclosed herein is directed to a record selector mechanism which includes a plurality of spaced-apart records to be individually selected and played by a transducer. The plurality of spaced-apart records are secured by coupling means to a common support shaft element and simultaneously rotated at playing speed. A transducer member is secured to a transport mechanism to be positioned adjacent the record to be played. The transport mechanism includes means for urging the transducer in either one of two directions so as to engage a selected one of diametrically opposed record surfaces which are rotating. A slide pointer is mounted at the exterior of the housing and movable along a linear path and adjacent spaced-apart indicia. The indicia identifies the records within the phonograph system and the pointer is used to select the desired record. The slide mechanism includes an actuator to be manipulated when the slide is adjacent indicia corresponding to the desired record.
