    Abstract: An interface system for interfacing a standard telephone set with a radio transceiver as part of a telephone network is provided. The radio transceiver may be a conventional cellular-type transceiver or other transceiver having typical control inputs and outputs similar to that provided by cellular transceivers. The interface system converts tone-dial or pulse-dial inputs from the telephone into a serial data stream for storage in the transceiver. The interface system automatically determines when the last numeral or digit is dialed and provides a send signal to the transceiver when such determination is made. The system responds to incoming call signals, such as alert signals, from the transceiver and rings the telephone accordingly. The system similates ring and dial-tone type signals under conditions typical of standard telephone set usage.

    Abstract: An automobile antenna system includes a loop antenna disposed along a marginal edge portion of the vehicle body of an automobile for detecting broadcast waves flowing on the vehicle body. A high-frequency pickup which includes the loop antenna is rigidly clamped between a pair of brackets which are secured to the vehicle body through a vehicle body connecting piece. Accordingly, the loop antenna and the end portion of the vehicle body connecting piece on which broadcast waves are concentrated are accurately positioned relative to each other.

    Abstract: An integrated cargo transportation security system is provided for a fleet of enclosed cargo transportation containers. Each container includes a subsystem including a door sensor for sensing access door opening and closure, a module unit including a connecting frame for a removable module and cabling leading to the door sensor. The identically appearing removable modules are configurable as active and passive. Each locks into the unit. The system includes a central data collection and processing facility for processing cargo trip data collected by at least one active module during a cargo trip of the container into a roadmap indicating travel route of the container during the trip and the time and location of significant event such as unauthorized opening of the cargo door. The module unit having an active module includes a self contained power supply, a location detector for detecting present location of said container, a clock, a central processor for generating a sequence of status numbers indicative of accumulated location, time and door status, and a memory for storing the sequence during the trip. The system further includes means for transferring the status number sequence to the central data collection and processing facility. A radio link may be provided to connect the container module to the central data facility in real time, and may be operated by authorized personnel at the container to signal predetermined conditions to the central facility.

    Abstract: A user connected by telephone to a central telephone exchange can inform an automatic switching communications device directly of his own telephone number by dialing on his telephone set, which determines the corresponding address and all other possible characteristics from an on-line directory. The available taxis are entered in a stand-by memory. The taxis in first place in the stand-by memory is provided with the assigned address by the switching communications device via radio. The total area serviced by the device for the switching communications exchange of the taxis, can be partitioned into individual sectors, whereby each sector then corresponds to its own stand-by memory. Therefore, a very quick and efficient switching communications exchange is possible without a large expenditure for personnel.

    Abstract: A telephone interconnect system for a two-way radio communications system is disclosed. A telephone patch interconnect unit accepts dialed digits from a telephone line, encodes them into a data packet, and couples the data packet to a fixed transceiver for transmission to remote units. A remote unit with a digit sequence identification matching the received and decoded dialed digit activates an alert. A remote unit may generate and store digits corresponding to a desired telephone number. The digits are subsequently encoded into a data packet and transmitted to the telephone patch interconnect unit. The interconnect unit accepts, acknowledges and decodes the data packet and couples the resulting digits to the telephone line.

    Abstract: An improved miniature antenna is disclosed which provides an electrically short radiation pattern by providing shielding of selected portions of a current carrying conductor forming a loop antenna. The shielding is provided so that the shielded portion of the loop antenna does not cancel the radiation from an unshielded radiating portion of the antenna, thereby producing a uniform radiation pattern. A plurality of the current carrying elements formed by the shielded and unshielded portions may be coupled in a series and parallel relationship to provide optimum impedance matching at the frequency of operation of a transmitter or receiver.
