摘要： A compression type refrigeration system including at least one frosting evaporator positioned to refrigerate air. The evaporator has a liquid refrigerant inlet to which is connected an expansion valve. The evaporator also has a hot gas inlet; a liquid line supplies liquid to the expansion valve; a branch in the liquid line controlled by a solenoid valve connects to the hot gas inlet. The condensing unit, which includes compressor, condenser, receiver and re-evaporator, are valve-controlled so that during refrigeration, discharge gas from the compressor flows through the condenser, receiver, liquid line and expansion valve seriatim, but during defrost, gas from the compressor bypasses the condenser and flows instead from the compressor through the receiver, liquid line and hot gas inlet of the evaporator seriatim.

摘要： A golf cart control and monitoring apparatus, includes a signal transmitter, at least one antenna, a signal receiving and processing device, and an event log device. The signal transmitter transmits a plurality of electromagnetic signals, each signal being representative of a position with respect to a restricted area of a golf course. The signal receiving and processing device receives the electromagnetic signals radiating from the antenna and provides output signals representative of the location of the cart with respect to the restricted area, where at least one of these output signals is representative of the golf cart being located in the restricted area. The event log device is responsive to the signal receiving and processing device and generates historical log of how long and how many times the golf cart was located within golf course restricted areas. In another embodiment, a plurality of ranging signals are transmitted from a number of antennas located at known location on the golf course and the signals receiving and processing device includes a microprocessor for determining the location of the cart with respect to the restricted area based on these ranging signals.

摘要： A golf cart control and monitoring apparatus, includes two antennas spaced from each other, two transmitters, two receivers, two alarms, an event counter, a time accumulator and a display for the events counted and the time accumulated. The two antennas are each disposed about a golf course restricted area and one antenna is disposed outside of the other. One transmitter transmits a first electromagnetic signal from one antenna which signal is received by the first receiver. The second transmitter transmits a second electromagnetic signal from the other antenna, which signal is received by the second receiver. The first alarm generates an alarm indicating that a golf cart is approaching a restricted area of a golf course in response to the first output from the first receiver. The second alarm generates another alarm, distinct from the first alarm, and an external alarm indicating that a golf cart has entered the restricted area in response to the second output from the second receiver. The event counter counts the number of times a golf cart enters into restricted areas and the time accumulator determines the cumulative amount of time the golf cart has been located in the restricted areas, wherein the accumulator begins to accumulate data upon receipt of the second output and stops data accumulation upon loss of the second output and receipt of the first output.

摘要： A golf cart control and monitoring system, includes a signal transmitter, at least one antenna, a receiving and processing apparatus, and an event log device. The signal transmitter transmits a plurality of electromagnetic digitally modulated signals. The receiving and processing apparatus receives the electromagnetic signals radiating from each antenna and processes the signals to determine the position of the cart with respect to each antenna and correspondingly with respect to the prespecified feature. A control signal is outputted therefrom representative of the location of the cart. The event log device is responsive to the control signals and generates historical log of how long and how many times the golf cart is located within course restricted areas. In another embodiment, digital signals are radiated from antennas proximate designated start areas, designated stop areas and designated intermediate cart travel positions to track time of play and to provide displays of same to a cart operator. The receiving and processing apparatus includes a memory to store the event device historical log and playtime information for later retrieval by course representatives.
