Abstract: A brine tank salt level detection apparatus is disclosed. The apparatus includes a housing secured to a lid of a brine tank, where the housing supports an infrared emitter and an infrared sensor. The apparatus is configured to emit an infrared signal, receive an infrared signal, and determine whether a salt level in the brine tank is below a predetermined level using, at least in part, the receipt of the infrared signal. A method for determining a salt level in a brine tank is also disclosed. The method can include emitting an outgoing infrared signal, receiving an incoming infrared signal, determining whether the salt level is below a predetermined level based at least in part on the receipt of the incoming infrared signal, and when the salt level is below a predetermined level, alerting a user of the low salt level in the brine tank.

Abstract: Described herein is technology for, among other things, controlling a pump submersed in a liquid, where the pump includes a plurality of capacitive sensors. The capacitive sensors include a first capacitive sensor and a second capacitive sensor disposed above the first capacitive sensor. The technology involves sensing liquid levels with the capacitive sensors, activating the pump after the second capacitive sensor detects the liquid in a normal mode of operation, deactivating the pump after the first capacitive sensor no longer detects the liquid in the normal mode of operation, detecting a failure of one or more capacitive sensors, and adjusting the operation of the pump to compensate for the failure of the one or more capacitive sensors.

Abstract: A tire-cleaning device for a wheelchair or other wheeled device, such as a scooter, which includes a pair of rotatably-mounted rollers positioned to support at least one wheel of the wheelchair. A rotatably-mounted cleaning brush is positioned between the rollers. The rollers are activated in a direction opposite that to the brush such that the rollers and brush rotate in opposite directions causing the brush to rotate in a direction opposite the tire of the rotating wheel of the wheelchair in order to effect the best cleaning mode. Cleaning fluid is drawn to the tire of the wheelchair by the rotating brush.
