    摘要: A local telephone/radio paging system includes a local paging system, a telephone, and a memory for indicating which telephone numbers are within the local area. When a telephone number is dialed, if the person dialed does not answer, the telephone switching equipment checks the memory to determine whether the dialed number is within the local paging area. If so, a local paging transmitter is activated, paging the person assigned to the unanswered phone. Such a paging transmitter may be included in each phone, or a single central local transmitter may be employed. The paging receivers desirably include alphanumeric displays and indicate the number of the telephone that originated the unanswered call, so that the person carrying the paging receiver may call back immediately.

    摘要: A system and method to autodial a telephone number, employing (1) an electronic wristwatch which includes means for receiving radio paging messages and a memory for storing a database of predetermined multidigit telephone numbers and (2) a collapsible compact telephone handset, which does not have a dialing key pad. The electronic wristwatch and the handset includes short range transceivers so that a data communication link can be established between the electronic wristwatch and the handset. Circuitry is provided to transmit telephone numbers stored in or received by the electronic wristwatch to the telephone handset and to automatically dial such telephone numbers.

    摘要: A wide area paging system is disclosed in which paging messages input to the system in one local area can be broadcast to a receiver in any other local area without necessarily broadcasting the message in all areas. A local area clearinghouse in each area stores resident subscriber data including current location and receiver serial number. This data is used to transfer messages over a data network to the correct clearing-house. The system uses a TDM data protocol. The data is encoded and transmitted at a very high rate (e.g., 19,000 baud) in short packets (256 bits/13 milliseconds) via stereo FM sidebands. Receivers are assigned to receive sequentially numbered time slots matching a portion of their address. The addresses of intended receivers are included in the data packets. Battery-powered receivers are deactivated between packets and reactivated in accordance with the sequential time slot number scheme to receive an incoming packet. Messages longer than a packet are segmented and transmitted in two or more packets, linked together by data contained in the packets. A watch pager used in the system employs a wristband antenna which electromagnetically couples to the user's body. The watch pager displays time, telephone numbers and icons representing common types of paging messages.

    摘要: A method and apparatus for transmitting paging and absolute time information to, and receiving such information at, a remote portable electronic timepiece and pager unit during a short time slot assigned to the pager unit is disclosed. In the pager unit, an oscillator is coupled to a timer which produces a time display. These functions are constantly powered. The timer periodically causes power to be supplied to a receiver and message decoding components of the pager unit during a short time slot in which transmitted data is to be received. The receiver detects and reconstitutes a transmitted signal. The transmitted signal is processed through a decoder which extracts paging and time update data. If the paging data includes the pager unit's ID number, the unit indicates that a page has been received. The time update data extracted from the transmitted signal is used to synchronize a timer in the pager unit. The timer provides an accurate time indication for the watch function. The same timer additionally determines when power is supplied to the pager unit's receiver and message decoder components so that they will be powered during the short time slot.
