摘要:
A digital wiring device including a user interface panel, a digital display, and a paddle including a transparent portion to reveal the digital display and an opaque portion to cover the user interface panel. The paddle rotates from a first closed position to a second open position. A digital “schedule-at-a-glance” may be provided so that a user can quickly assess a schedule of events. The digital wiring device may include a back light to illuminate the digital display. The paddle may be operatively associated with the back light. A battery may provide an electrical current to power the digital wiring device in a battery backup mode, and the back light may be disabled based on the mode. The user interface panel may be used to schedule events or otherwise configure the digital wiring device.

A supplemental control system for a materials handling vehicle comprises a wearable control device, and a corresponding receiver on the materials handling vehicle. The wearable control device is donned by an operator interacting with the materials handling vehicle, and comprises a wireless transmitter and a travel control communicably coupled to the wireless transmitter. Actuation of the travel control causes the wireless transmitter to transmit a first type signal designating a request to advance the vehicle in a first direction. The receiver is supported by the vehicle for receiving transmissions from the wireless transmitter. A traction control of the vehicle is responsive to a receipt of the first type signal by the receiver to cause the vehicle to advance.

A trainable transceiver for learning and transmitting an activation signal that includes an RF carrier frequency modulated with a code for remotely actuating a device, such as a garage door opener. The trainable transceiver preferably includes a controller, a signal generator, and a dynamically tunable antenna having a variable impedance that may be selectively controlled in accordance with a detector circuit signal. The detector circuit provides a measurement of the transmission power and is also used to vary the applied transmission power of the transceiver in response to operating and environmental parameters.

A multiphase inductive power supply wirelessly transmits power in multiple phases. A primary circuit energizes multiple tank circuits in an out of phase relationship. A secondary circuit receives the power and recombines the power. The amount of energy in each phase is reduced compared to transferring the same amount of power using a single phase inductive power supply.

A method of associating a transmitter and a receiver in a supplemental remote control system for materials handling vehicles includes initiating a power on sequence to enable a vehicle for operation, the vehicle having a receiver for receiving wirelessly transmitted travel commands, and pairing and synchronizing the receiver and a corresponding vehicle controller to a select one of a plurality of wireless remote control devices. Pairing mode confidence signals are received at the vehicle receiver, wherein each pairing mode confidence signal provides a transmitter identification that uniquely identifies a corresponding wireless remote control device within range of the receiver. A known transmitter identification code associated with the select wireless remote control device is matched with a corresponding one of the pairing mode confidence signals received by the receiver, and the matched wireless remote control device is synchronized to the receiver and the controller of the vehicle for communication therebetween.

A method and system relates to locating or otherwise generating positional information for an object, such as but not limited generating positional coordinates for an object attached to an athlete engaging in an athletic event. The positional coordinates may be processed with other telemetry and biometrical information to provide real-time performance metrics while the athlete engages in the athletic event.
