Abstract: Selectable receiver addressing is used to control how messages are output from different receivers. Users selectively enable and disable personal addresses in the receiver. The receiver polls time slots where the data for enabled addresses may be transmitted. Enabled addresses are compared with transmitted receiver addresses. If the transmitted address matches one of the enabled receiver addresses, the message is output to the receiver user. If the transmitted address does not match the receiver address, the message is not processed and, accordingly, the receiver operator is not disturbed.

Abstract: A wireless telecommunications system is disclosed that provides both telecommunications service and navigational assistance to travelers. In particular, the present invention addresses three common navigation problems.

Abstract: A communication system, method, and multiple master and slave transceivers having automatic addressing and collision avoidance. A master transceiver is programmed with its address by a user through a host. After being turned on, a slave transceiver acquires its address as the address of the first message it receives from a master transceiver. The master and the slave transceivers then communicate in each direction and ignore other messages by using that address until the slave transceiver is turned off. When the slave transceiver is turned on again, it acquires a new address of the address of the first new message it receives from a master transceiver, not necessarily the same master transceiver. The transceivers communicate with a signal having an on-condition having different lengths for representing different symbols.

Abstract: A wireless selective-call receiver makes use of detection or absence of any to-and-fro movement of the receiver indicating that the receiver has been left somewhere thereby improving the security function of the receiver. When a motion detector detects no continuous shaky movement of the receiver, the message received by the receiver is stored in memory. A controller comprises a first control section which operates in a no movement condition, a second control section which operates in a moving condition, and a switching means for switching from the first control section to the second control section and vice versa. In the absence of the to-and-fro movement of the receiver (for example, the receiver is put away from the owner's body to be left on the desk), any access through a button inputting console and external interface except inputting a password is rejected. The message received is stored in memory, and not given on display, thereby preventing pieces of private information from leaking.

Abstract: The message transmitter transmits a re-calling identification signal with a message, and a receiver identifies this signal. Thereby the message transmitter can indicate selectively the re-calling of the receiver. If the message is not confirmed, the receiver performs re-calling according to a previously set time interval with a second sound pattern different from the normal sound pattern for indicating that this message is an unconfirmed message until the message is confirmed. The receiver continues to perform the calling operation periodically until the receiver holder cancels the re-calling. Meanwhile the message is confirmed by switch operation with a third sound pattern of three short sounds which are not noisy.

Abstract: A receiver, and a method for operating the receiver, for a station in a wireless local area network using a common wireless communication channel and employing a CSMA/CA (carrier sense multiple access with collision avoidance) protocol includes various modes. In normal mode, the receiver follows typical states in order to detect a message and demodulate data from the message properly. Meanwhile, a process implements a message-in-message (MIM) mode when an energy increase above a specified level is detected. While in the MIM mode, if a carrier is detected, the energy increase is caused by a new message; otherwise, the energy increase is caused by an interfering station. If the carrier is detected, the receiver begins retraining so that it can start receiving the new message as soon as the first message ends. If no carrier is detected, the receiver waits a specified time to detect a carrier or for the end of the first message, after which the receiver returns to the beginning of the normal mode.

Abstract: A central station and each base station have a timer indicating time instants coincident with each other. A common transmission start time instant is provided from the central station to each base station so as to match the transmission start time instant to start transmission of the signal frame in each station. The central station makes the call requests of different bit rates contained in one signal frame and broadcasts to each station the transmission start time instant for the signal frame, the order of the call requests within the signal frame, and bit rate switch timings. When the transmission start time instant arrives, the base station reproduces call signals from the call requests in accordance with the designated order. Reproducing clock pulses are switched with reference to the bit rate switch timings sent from the central station. Thus, each station can transmit the call signals of the different bit rates in one signal frame with their phases coincident with each other.

Abstract: When a transmit station pages a pager which has the paging area of that transmit station as its local area, it pages using an address which is unique in that area. When a pager with another local area has moved into this paging area and is paged, it is paged using the area identification number of its local area and the address of its receiver. Each pager can therefore be paged in any given paging area without having to be given a separate address for each paging area.

Abstract: Pager data is transmitted at different subcarrier frequencies on different FM broadcast channels. The subcarrier frequency of the pager data is selected to avoid conflicts with signals transmitted from other systems. The pager receiver decodes data at any one of the multiple subcarrier frequencies according to the active subcarrier used on the currently tuned broadcast channel. In one embodiment, the subcarrier frequency of the pager data is contained in control packets of a time division multiplexed data frame. The receiver decodes the control packets to determine which broadcast frequencies and associated subcarrier frequencies contain potential pager signals. The receiver accordingly searches the identified broadcast frequency and automatically reconfigures a circuit demodulator to decode data packets at the identified subcarrier frequencies.
