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.

Temperature probe with food-embedded charging contacts

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.

Wireless temperature-measurement system

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.

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.

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.

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. Pressure transition times during pulsation cycles are varied at the beginning, middle and end of a milking interval to provide a faster rate of liner opening movement and/or larger diameter liner opening at the beginning of the milking interval to provide deeper teat penetration into the liner, an intermediate rate of liner opening movement and/or intermediate diameter liner opening during the middle of the milking interval, and a slower rate of liner opening movement and/or smaller diameter liner opening at the end of the milking interval to limit loss of adhesion between a less than full teat and the interior of the liner. The repetition rate of the waveshape may be varied to provide a plurality of pulsation cycles of variable duration, further reducing milking time. The pressure is further varied during both on portions and off portions of the pulsation cycle at a higher frequency than the repetition frequency of the pulsation cycle to stimulate milk flow.

Milking system with variable pressure source

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.
