  • Patent number: 6512748
    Abstract: A radio paging signal coding control scheme capable of improving the reception characteristic of the receiver by carrying out a coding control to determine logical channels for accommodating paging signals such that the transmission rate equivalently becomes as low as possible according to the paging signal traffic, without interrupting the paging signal coding processing while maintaining the combination of transmission rate and modulation scheme for frames, is disclosed. In the case of using prescribed transmission rate and N-valued modulation scheme, logical channels to be used for transmission of paging signals among a plurality of available logical channels are determined by setting priority orders among a plurality of available logical channels such that a number of states of modulated signals becomes less than N when paging signal traffic is small.

  • Patent number: 6301230
    Abstract: In a radio paging system wherein a user carrying a radio paging receiver is paged by means of radio waves, and the radio paging receiver sends back a response signal when it has received a paging signal addressed to itself, the response signal is sent back by means of direct sequence modulation using a code uniquely determined in accordance with the base station ID signal, which is different for each base station, and which has been inserted in the paging signal sequence transmitted from the base station, or in accordance with the order of each paging signal within the paging signal sequence. As a result, the response signal can be transmitted at low power from each radio paging receiver, and effective utilization can be made of frequency, regardless of an increase in the number of radio pagers.

  • Patent number: 5815139
    Abstract: The present invention concerns a relative manipulated variable input device which is capable of controlling the cursor movement in correspondence to the direction and amount of tilt of a control button and controlling the speed of the cursor movement in accordance with the force applied to the control button as well. Output data is generated using relative position data calculated from the difference between a pressed position and a reference position and a contact resistance value r.sub.p. The output data, which represents the direction and amount of tilt of the control button, is output in accordance with the force applied to the control button. The relative position data represents the direction and amount of tilt of the control button and the output data is produced based on the relative data. Hence, the cursor movement can be controlled by the direction and amount of tilt of the control button, and by changing the force exerted on the control button to change the contact resistance value r.sub.

  • Patent number: 5777560
    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.
