Abstract: A communications device such as a personal identity card is in the form of a badge or label worn on the outside of the wearer's clothing. The badge includes a first layer of a transparent material having an inner surface that is contoured with a retroreflecting repeating pattern. A second layer also of a transparent material has an inner surface with a reciprocating retroreflecting pattern. Sandwiched between the two layers is a layer of liquid crystal material the refractive index of which can be varied through the application of an electric field. When the refractive index of the layer is close to that of the first and second layers, incident radiation passes through the device with little scattering. However, as the refractive index of the layer is varied by application of an electric field, incident radiation is retroreflected from the contoured interface of the first layer with the layer. The communications device is capable of retroreflecting incident radiation and modulating the radiation, by altering the refractive index of the layer, so that the reflected beam is capable of delivering information to a receiver. In this way information can be delivered in a non-contact environment using a device that requires very little power to operate.

Abstract: A connecting rod assembly for rocking piston compressors, diaphragm compressors and vacuum pumps is provided where the overall height of the connecting rod assembly is dependent only upon the overall height of the connecting rod structure and is not dependent upon the thickness of the diaphragm or the thickness of the retainer plate. The connecting rod includes a disk portion for supporting an annular diaphragm in the case of a diaphragm pump or a cup in the case of a rocking piston compressor or a vacuum pump. The connecting rod also includes a distal end section that extends upward through the annular diaphragm and through an annular retainer plate. The diaphragm or cup is sandwiched between the annular retainer plate and the disk portion of the connecting rod. The overall height of the assembly is determined by the distance between the end face of the disk portion of the connecting rod and the crank end of the connecting rod. The annular retainer plate bottoms out on the disk portion of the connecting rod and therefore does not contribute any height variability to the assembly. Because the diaphragm or cup is trapped below the annular retainer plate, the diaphragm does not contribute any height variability to the assembly as well.

Abstract: An improved repeater adds on to each mobile transceiver of a radio wave communication system for selectively controlling rebroadcasts to an associated portable station. Novel circuitry within each associated repeater eliminates rebroadcast interference among local units, while keeping retransmission delay at an optimized minimum.At turn on, detector circuitry senses if a nearby repeater is broadcasting. In response thereto, programmable delay circuitry is activated to a high incremental state. Where no repeater broadcast is sensed, a program signal is transmitted which increments all nearby repeaters to their next higher delay state. On reception of a signal to be rebroadcast, the repeater whose delay circuitry is in the lowest incremental state initiates rebroadcast, thereby inhibiting the remaining units.A special feature of the programmable delay circuitry is that each repeater is automatically assigned a unique incremental delay time whereby repeater prioritization is positively established. Rebroadcast delay time is kept to a minimum as the system assures that one repeater is at the lowest delay priority.BACKGROUND OF THE INVENTIONThe present invention relates generally to radio wave communication systems of the type employing a base station, a plurality of portable stations and a plurality of mobile repeating stations, and more particularly to improved means for, and a method of, assigning a rebroadcast priority to the repeaters in such systems in a mamnner to minimize undesireable interference.Mobile ratio wave communication systems normally comprise a base station and a plurality of mobile stations, each of which is typically located with an automotive vehicle. In many applications, such as police work, it is important for the user to maintain communication with the base station or other mobile transceivers upon leaving his mobile vehicle. To resolve this problem various repeater add-on systems have been proposed. Generally, such systems interconnect with the mobile transceiver whereby the audio signal from the transceiver is reprocessed through a second transmitter and broadcast on a second frequency to a portable transceiver. Likewise, signals from the portable transceiver are received in a second receiver and applied to the mobile transceiver where they are broadcast back out on the mobile-base station frequency.A problem with such repeater systems occurs when a plurality of mobile transceivers are in the same locale. In this situation each repeater will attempt to rebroadcast base station, mobile, or portable transmissions. Simultaneous broadcasts by nearby repeaters results in interference creating loss of intelligibility of the transmitted signals. One solution to the interference problem is to operate the various repeaters and their respective portable transceivers on different frequencies. However, this anticipates a complicated and cumbersome system.A second solution, known in the art, contemplates a random sampling technique. Accordingly, a random sampling generator is to be included in each repeater in the communications system. Once a signal to be retransmitted is received the first repeater whose random sampling generator creates an enable pulse following the received signal transmits a lockout to any other repeaters and proceeds to repeat the incoming information. This system has several undesirable drawbacks. First there is a considerable delay time introduced by the sampling function. This delay is in addition to the normal attack times of a transmiter or receiver. The increased delay time might be as long as the disable period of a random sampling generator. Further, there remains a significant probability of interference among transceiver units using the random sampling method. Finally, if the sampling generators are identical and enable pulses occur at similar times in two or more units there is the possibility that the pulses may tend to remain in synchronism and interference would occur on each transmission. The only means to break the interference would be waiting until the enable pulses drift out of synchronization or to shut off one of the offending repeaters.OBJECTS OF THE INVENTIONIt is an object of the present invention, therefore, to provide a repeating system which eliminates interference between nearby repeator units.It is a further object of the present invention to provide a repeating system as described above which initiates rebroadcasts with a minimum delay time.A further object of the present invention is to provide a repeating system as described above which is fully automatic in operation.Briefly, according to the invention, a radio wave communication system comprises a base station and mobile stations broadcasting signals at a first frequency, a portable station receiving signals broadcast at a second frequency, and a plurality of repeaters receiving signals broadcast at a first frequency and rebroadcasting said signals at the second frequency. Each repeater comprises delay circuitry delaying rebroadcasts for a programmed time period; a detector sensing for signals broadcast at the second frequency during the delay period and including means inhibiting repeater rebroadcast in response to a received detect signal; and means for programming the time delay.The programmed delay circuitry includes a clock, a counter, and comparator means instituting rebroadcast at a predetermined count. The counter outputs a high count in its first mode and an initial count in its second mode. Further, the counter is adapted to increment its count output in a first polarity responsive to received program signals, and in a second polarity in response to input clock pulses. On reception of a signal to be rebroadcast, the clock initiates and begins counting down the counter. The first repeater to be incremented to its lowest state is the first to satisfy the comparator whereby retransmission occurs locking out the remaining repeaters.Repeater programming occurs when a portable unit is removed from the repeater mobile transceiver. At this time the repeater senses whether or not a transmission is occurring on the second frequency, acting to transmit a program signal incrementing all nearby repeaters to the next higher counter state in the absence of a second signal, and otherwise incrementing its own counter to a higher state if a detected signal is present. Thus, generally, the last repeater to enter an area will be the one in the lowest incremental state, hence the one to repeat all transmissions. Should the repeater in the lowest counter state leave the area, a remaining repeater in the second highest priority will rebroadcast after its time delay, and reset its own counter to the lowest state whereby minimum time delay is established for subsequent transmissions.
