Abstract:
In one embodiment, there is a fault interrupter device comprising at least one sensor comprising at least one first transformer having at least one outer region forming an outer periphery and at least one inner hollow region. There is also at least one second transformer that is disposed in the inner hollow region of the at least one first transformer. The transformers can be substantially circular in configuration, and more particularly, ring shaped. In another embodiment there is a rotatable latch which is used to selectively connect and disconnect a set of separable contacts to selectively disconnect power from the line side to the load side. The rotatable latch is in one embodiment coupled to a reset button. In at least one embodiment there is a slider which is configured to selectively prevent the manual tripping of the device.
Abstract:
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.

The wireless communication between the transceiver and the cellular phone utilizes a Bluetooth communications protocol.
Abstract:
A system and method for detecting light fixture failure and for enhancing energy efficient operation of multiple light fixtures. The system includes multiple light control modules and a gateway. The light control modules alert the gateway of a bulb or ballast failure based on light fixture power consumption. The light control module can indicate a sudden failure, a slow failure, a striating failure, a stuck relay failure and a start-up failure. The light control modules can include a photo-sensor and an occupancy sensor for measuring brightness and occupancy, respectively, in the vicinity of one or more light fixtures. The gateway can distribute operating instructions to the light control modules based on changes in the ambient temperature and based on the power consumption of nearby light fixtures.

Abstract:
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.
