Abstract: Various hard hat fan systems are provided. In a certain embodiment, fan system includes an impact absorbing layer with a channel that defines a recessed surface which extends into the impact absorbing layer away from an inner surface of a shell of a hard hat. Together, the inner surface of the shell and the recessed surface define a duct configured to provide fluid communication between an inlet of the channel and an air vent positioned along the channel. In another embodiment, fan system includes a mounting bracket with first and second cam levers which may be actuated into a locked position, and first and second channels. When in the locked position, the first and second cam levers bias the edges of a mounting ridge of the shell against the first and second channels of the mounting bracket such that the mounting bracket is retained on the shell.

Abstract: In one aspect, an apparatus is provided for a conveyor belt system. The apparatus includes a conveyor belt cleaner having an elongate support and a pair of mounts configured to position the elongate support to extend across a conveyor belt. The apparatus includes a cleaner blade configured to be operatively mounted to the elongate support and engage a conveyor belt. The apparatus further includes a sensor configured to detect at least one characteristic of the elongate support as the elongate support vibrates during conveyor belt operation. A processor of the apparatus is configured to use the at least one characteristic of the elongate support to predict at least one property of the cleaner blade.

Abstract: An elongated spine extends vertically within a refrigerated cabinet, freezer cabinet, or doors and includes ductwork for the transmission of fluids within the spine as well as operating power and/or electrical control or data signals. The spine includes a mounting channel having inwardly extending edges. Modules mate with the spine for the physical mounting of the modules at any desired location within the continuously extending channel and are provided with a flange which fits within the spine and mounts the module in a cantilevered fashion to the refrigerator. Such construction facilitates the distribution of fluids, such as hot or cold air within the refrigerator, and the manufacturing of a refrigerator by providing a readily attached spine and allowing modular construction of a refrigerator with infinite adjustability for the user.

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.

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.
