A system includes a remote control device that is useable by an operator interacting with a materials handling vehicle. The remote control device includes a wireless communication system including a wireless transmitter and a rechargeable power source. The system further comprises: a receiver at the vehicle for receiving transmissions from the wireless transmitter; a controller at the vehicle that is communicably coupled to the receiver, the controller being responsive to receipt of transmissions from the remote control device; and a charging station at the vehicle, the charging station for charging the rechargeable power source of the remote control device.

On-board charging station for a remote control device

A remote control device that is paired with a first vehicle, such that the remote control device wirelessly communicates with the first vehicle, is paired with a second vehicle via a pairing process. The pairing process is initiated by physically contacting a component of the remote control device with an element of the second vehicle. The pairing process also unpairs the remote control device from the first vehicle, such that the remote control device no longer wirelessly communicates with the first vehicle, and the remote control device wirelessly communicates with the second vehicle.

Pairing a remote control device to a vehicle

The specification discloses a monitor, a system, and a method for monitoring the electrolyte level in a cell of a multi-cell battery. The system may be powered by leads attached across any one or more cells of the battery. The system includes an electrically conductive probe, having its own wire, that may be installed in any battery cell. The probe is current sampled to provide one or more signals used to determine if the probe is in physical contact with the electrolyte (indicating acceptable electrolyte level). The probe may be sampled as a cathode and as an anode. The probe may be sampled using PWM (pulse width modulation). The probe may be sampled using current limiting.

Battery electrolyte level monitor, system, and method

A liquid level sensor for a liquid electrolyte battery is provided. The liquid level sensor includes a probe having a reference electrode and an electrode array. The electrode array includes a plurality of electrodes that are serially disposed in a lengthwise direction of the probe. The reference electrode is capacitively coupled to each electrode within the electrode array, such that the probe provides a capacitance that varies when the probe is immersed in a liquid level that varies in relation to the probe. The liquid level sensor can alert a user of the need to refill the battery or alert a user of the need to refill the battery in the near future. The liquid level sensor can include a series of LEDs that selectively illuminate to indicate each such condition to the user.
