Abstract: A wireless rechargeable temperature probe for food, the probe having an elongate body, a proximal end portion and a distal end portion, the distal end portion having a temperature sensor therein and including a probe tip and a food-embedded portion, wherein the distal end portion includes two electrical-charging contacts electrically-isolated from one another, the electrical-charging contacts both being embedded within the food during use in order to prevent difficult cleaning.

Abstract: A wireless temperature-measurement system comprising (a) one or more temperature probes each including one or more energy-storage capacitors which supply the electrical energy for operation of the probe(s) and (b) a probe-charging station having circuitry configured to supply electric charge to the energy-storage capacitors prior to the temperature probes being positioned to measure temperature.

Abstract: A wireless, proximity-based security system for securing or tracking a valuable object. The system includes a base station and a plurality of security fobs. The security fobs are tracked via an ultra-wideband transceiver relative to an outer perimeter. An administrator fob pairs each of the security fobs with the base station. An audible alarm emits from base and/or the fobs when the location of the security fob is detected to be beyond the outer perimeter. A haptic alarm emits from fob when the location of the security fob is detected to be beyond a sub-perimeter.

Abstract: Actuation sensor apparatus configured to removably attach to a liquid dispenser, the apparatus comprising (a) an electronic circuit including a dispense sensor and a wireless transmitter and (b) a power supply for the electronic circuit, whereby, when dispenser actuation occurs, an identification code unique to the apparatus is wirelessly transmitted to a receiver. In a preferred embodiment, the dispense sensor is a magnetic sensor and the apparatus further includes an actuator arm having a magnet, and the actuator arm is configured to move with respect to the magnetic sensor during actuation.

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.

Abstract: An adjustable leg includes a foot assembly, a leg assembly, a tube assembly and a rod assembly. The foot assembly is coupled to the leg assembly. The rod assembly is rotatably coupled to the tube assembly. The rod assembly is threaded through an aperture in the leg assembly and the tube assembly. The rotation of the rod assembly adjusts the overall length of the adjustable leg. Engagement of the leg assembly with the inside of the tube assembly prevents the rotation of the tube assembly when the rod assembly is rotated.

Abstract: A milk meter (22) has a measuring chamber (40) with an inlet (42) receiving milk from a mammal's teat (24), a discharge chamber (48) having an inlet (50) from the measuring chamber and an outlet (52) discharging the milk to a collection tank (32), a central vertically reciprocal plunger valve (46) opening and closing the outlet of the measuring chamber and communication vacuum from the discharge chamber through the plunger to the measuring chamber, and a level sensing float (56) in the measuring chamber and circumscribing the plunger valve and vertically reciprocal therealong.

Abstract: A milking system uses a variable pressure source and varies the pressure supplied to the pulsation chamber along a controllably variable pressure curve of selectable waveshape. Pulsation cycles are shortened by shortening the transition time between pressure levels providing on and off portions of the pulsation cycle. The pulsation chamber is sequenced through different pressure change rates, all during the transition.

Abstract: A portable self-contained milk flow indicator is provided for dairy barn applications. The milk flow indicator consists of a milk sensing device, a timing and switching circuit, indicators of the condition of milk flow, and a rechargeable battery, all sealed in a self-contained portable unit which can be used at any point in the milk line of a conventional dairy barn milking operation. The indicator is also provided with a battery charger which can be mounted on the wash manifold of a dairy barn milk house so that when the indicator is placed on the wash manifold for cleaning the battery, housed in the indicator, will automatically be recharged.
