  • Patent number: 5561701
    Abstract: A global radio paging system in which a plurality of radio frequency carriers having the same frequency are synchronously modulated in a plurality of base stations corresponding in number to the radio frequency carriers with the same digital paging signal and transmitted, respectively. A paging controller which receives paging calls through a public switched telephone network stores preliminarily the maximum value of a sum of a paging request signal transmission time in a transmission line and a time required to process the paging request signal in each of the base stations and a high precision time signal is produced on the basis of a reference signal from a GPS (Global Positioning System) satellite. A transmission time assigning code is attached to the paging request signal, which assigns a time instance which is delayed from a current time determined by the high precision time signal by the maximum value of the sum of the transmission time and the processing tame as a transmission start time.

  • Patent number: 5430437
    Abstract: In a pager receiver for receiving first through N-th pager signals successively at a first predetermined period (T1) and comprising a battery saving switch and a receiving circuit connected to the switch and enabled while the switch is in an on state, a controller puts the switch in the on state repeatedly at a second predetermined period (T2) to make the receiving circuit receive at least a portion of a preamble signal (PA) and whole of a synchronization (SS) and an address (AS) signals of the first pager signal (RS1) and detect an address signal end of the first pager signal. The controller keeps the switch in the on state to make the receiving circuit receive at least a part of the preamble signal and whole of the synchronization and the address signals of each of the second (RS2) through the N-th pager signals and detect the address signal end of each of the second through the N-th pager signals.

  • Patent number: 5291192
    Abstract: This improved paging system not only detects an omission of a message reception, but also acquires an unreceived message. When a normal paging request call is made from a public telephone network, the paging control unit adds to the received request a message counter including the called subscriber's number and then transmits an encoded paging signal which includes the received request. Further, a control unit stores the message data in a storage unit corresponding to a value of the counter of the called subscriber's number. The called pager detects an omission of a message reception through the received message counter value by comparing it with the message counter value of the last received message signal. A displayed message indicates an omission as well as the value of the omitted message. Thus, a call can be made through a public telephone network to request a repeated transmission.

  • Patent number: 5042083
    Abstract: A single-frequency signal communications system such as a paging network includes plural communication groups, each of which includes one master station and plural slave stations. The master stations of at least adjacent groups are within each others' reception zones. To avoid signal collision problems, each master station refrains from initiating transmission of a data signal unitl it has failed to detect the carrier signal of any other master station for a time period T. The designated slave station acknowledges receipt of the data signal by transmitting an acknowledgment signal within a period t after receiving the data signal. The time period T is greater than the time period t in order to avoid master station-slave station signal collision problems.

  • Patent number: 4783654
    Abstract: A radio paging system for transmitting address signals and messages, as well as information common to a plurality of receivers, and a receiver applicable to such a system. The radio paging system includes: an encoder which produces a first code, followed by a string of address codes each of which is followed by message codes, and a second code followed by a string of information codes, a transmitter for transmitting a string of codes produced by the encoder; and a receiver which upon detection of the first code produces an alert signal and displays the message codes when the address code agrees with an address code stored in memory, and which, upon detection of the second code, displays the information codes which follow.

  • Patent number: 4758834
    Abstract: A pager receiver for a radio calling signal carrying a call number and/or a message comprises a processing unit for producing a drive and an information signal to produce ordinary tone or tones related to the call number and to provide ordinary visual displays representative of the message, respectively. A processed signal is produced by the processing unit to provide extraordinary tones peculiar to a message-absent call, a message-present call, and a repeat call for repeatedly displaying a prior message. The processed signal also appears to provide extraordinary visual displays unique to the message-absent call. When the pager receiver has a plurality of preassigned call numbers, the processed signal is produced to provide such extraordinary displays inherent to each of the respective preassigned call numbers. In addition to the extraordinary displays of the preassigned call number, a plurality of messages are successively stored in a memory in a predetermined order to be successively displayed one by one.

  • Patent number: 4753824
    Abstract: A fluid dispensing system comprises an automatic hot melt fluid adhesive dispensing gun block for dispensing the adhesive onto a surface rotatably connected to a working arm of a programmable working machine. A nozzle is attached to the gun block and communicates through a rotatable spindle on the gun block and a hose with a source of fluid. The gun block is rotatable about an axis extending perpendicularly through the nozzle and to the surface onto which fluid is dispensed. Fluid is dispensed from the nozzle in a direction parallel to the surface. The gun block is rotatable such that the nozzle can maintain a uniform orientation to the dispensed fluid regardless of the relative direction of motion between the gun block and the surface receiving the fluid. Methods of using the fluid dispensing system are disclosed.

  • Patent number: 4720710
    Abstract: A testable pager including a receiver for demodulating a sequence of signals, and a manually operated switch. A controller receives the outputs of the receiver and the switch. The controller thereby switches on a power supply for the receiver for a set period after the start of the signal sequence. When the sequence includes a test code, the power supply stays on and a first test is performed. Actuations of the switch cause further tests to be made.

  • Patent number: 4682148
    Abstract: A radio paging receiver for receiving a carrier wave modulated paging signal which includes a preamble, an address code and a message, is composed of at least a receiver section, a waveform shaping circuit, a memory section, a control section, a speaker with driving sectionto sound an alert signal and a display section. The memory section stores a predetermined number of received messages, which are counted as they are received by a counter in the control section. The display section under the control of the control section, produces a three part display, the first part being an indication of the age of the displayed message relative to the other messages stored in memory, the second part the call type, when a dual call service is implemented, and the last part one of the messages stored in memory. If a message is being displayed as a new message is received, the previous message continues to be displayed, while the new message is stored in memory if memory space is available.
