Abstract: A page receiver is provided a list of alternative paging channels to which it can tune if the paging channel presently being received becomes unreliable. This list, and other lists used by paging receivers in the other geographical areas, are disseminated by linked paging transmitters that broadcast identical paging signals throughtout a large geographical area. When a paging receiver finds a channel carrying paging data, it identifies which of the plurality of transmitted lists is appropriate for its use by finding the list that references the channel to which the receiver is presently tuned. The channels referenced in the identified list are then stored in a memory and may be tuned if the existing paging signal is lost. Data is desirably transmitted with the local channel lists to permit each paging receiver to locate the list relevant to its geographical area without examining each of the transmitted lists.

Abstract: A paging system where messages are numbered before they are transmitted. The paging receivers in the system compare both the number and the text information in each message which is received to the message number and the text information in the most recently received previous message. The comparison is used to determine if the same message was previously received and if the any messages were missed. The receiver includes an icon which is turned on to indicate if a message has been received. The icon is set to a blinking state if a message is received and if there is a break is the sequence of message numbers indicating that a message has been missed.

Abstract: The present invention provides a pager system which integrates a plurality of transmitters which operate at different frequencies. Some of the transmitters transmit paging messages using FM subcarrier signals (termed FM-SCA signals) and some transmit messages using a modulated carrier (termed RCC signals). The receiver includes two front ends. One front end receives and demodulates FM-SCA signals and one front end receives and demodulates RCC signals. Each paging message is transmitted on both FM-SCA transmitters and on RCC transmitters. The signals on each of the transmitters are slightly off set in time. When an assigned time slot occurs, one receiver turns on and attempts to receive a message, if it does not receive an appropriate signal, it tunes to another station that is in a stored list of stations. If the next station has an RCC flag associated therewith the RCC receiver rather than the FM-SCA receiver is operated. The entire process is controlled by a microprocessor which is a part of the system.

Abstract: 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 clearinghouse. 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.

Abstract: A radio paging network transmits non-paging data, such as facsimile images, to lap top computer receivers by formatting the data into a series of packets and interleaving these packets, on a space available basis, into the paging signal.

Abstract: 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.

Abstract: A paging system transmits consecutively numbered page messages to receivers. Receivers detect missing page messages by interrogation of received page message numbers, and a missing page message is indicated by a gap in received page message numbers. However, page messages may be separated by long time intervals and a gap in received message numbers can not be detected until a subsequent page message is received. To more immediately detect a missing page message, a sequence message generated by the paging system provides a last transmitted page message number to receivers during otherwise unused portions of the transmission bandwidth. The receivers can thereby detect missing page messages without waiting until receiving a subsequent page message and without depleting the transmission bandwidth resource.

Abstract: A paging system using synchronized transmission protocol and remote pagers active during monitor intervals to receive data transmitted during corresponding message intervals is provided with adaptive on-off radio receiver control for reducing monitor interval duration to conserve battery power and for centering message intervals within corresponding monitor intervals to increase message reliability. The adaptive on-off control is a function of a recent history of timing errors and thereby accounts for environmental conditions.

Abstract: 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.

Abstract: A paging system and method utilize a trunk interface module which is capable of recognizing unique identification numbers, which comprise the telephone number which a caller dials to reach a particular paging receiver. The relative-digit-independent truck interface module is located between the telephone company central switch and the computer in the central clearing house and is capable of recognizing and relaying a set of at least seven digits, which comprise the unique receiver's identification number, wherein the values of the digit and the identification number are completely random, i.e., the digits are not necessarily representative of telephone numbers/identification numbers, in a particular telephone exchange. The system also includes a separate inward dialing portion which does not use the interface module and which requires the manual entry of receiver identification numbers.

Abstract: An electronic circuit, such as the type which may be found in a watch pager receiver, which contains both analog and digital circuitry, includes harmonic noise minimization circuitry. The minimization circuitry is constructed using standard cell designs which are optimized for particular clock operations. Select circuit components are optimized to produce minimal harmonics, to operate at the predetermined frequency and include resistance means to provide an output of a second known level which is characterized by an optimized output signal having a ramped wave configuration. The optimized output signal is of adequate strength to provide an input to a downstream component.

Abstract: The present invention provides a technique and system for modifying the modulation of the 66.5 kHz subcarrier in such a way that its spectrum will not overlap that required by the 57 kHz subcarrier, while at the same time maintaining compatibility with existing subcarrier receivers. A special signal is created whose spectral shape is asymmetrical with respect to the 66.5 kHz subcarrier. In the frequency domain, the lowest frequency part of the symmetrical spectrum is cut off, flipped about the carrier frequency and then added to the highest frequency part of the spectrum. This technique and system takes advantage of the fact that the receiver, with which the system is designed to operate, uses a sampling process which products frequency aliasing.

Abstract: The infiltration of an impurity, such as phosphorus or boron, from a lower layer or interconnect into a higher layer or interconnect can be prevented without sacrificing the established high resistance characteristics of a formed high resistance region in the latter through the employment of a thin nitride film of an appropriate material and thickness positioned at the interface between the lower layer and the high resistance region. This technique minimizes any detrimental shortening of the high resistance region formed in such a layer or interconnect making it suitable for increased density and higher levels of integration of semiconductor devices.

Abstract: A wristwatch paging receiver is provided with an antenna matching network that automatically retunes the network at the beginning of a listening interval. During the retuning operation, a control signal is applied to a variable tuning element in the matching network, such as a varactor diode, and is swept from a minimum value to a maximum value. This sweeping is desirably performed in discrete voltage steps that correspond to unit increments of varactor capacitance. A feedback signal from the receiver, such as an AGC signal, is monitored during this operation to note which varactor bias signal yields the maximum AGC signal. After the sweep is concluded, the apparatus applies to the varactor the bias voltage that yielded the maximum AGC signal during the sweeping operation. This bias voltage is maintained through the end of the listening interval. At the beginning of the next listening interval, the process may be repeated.
