Granted: 1998-08-11
Abstract: Weight of a person in bed is detected by a piezo-electric element 13 without contacting to the body, and time measurement is reset and started newly by a timer, every time when a detected output exceeds a predetermined set value.  When the measurement time of the timer exceeds a set time predetermined, it is judged that the body has fallen asleep on the bedding.  Meanwhile, absence or presence in bed and rough body movement are judged by detecting the  fine body movement propagated by the functioning of heart and breathing of the body, and in case the presence in bed is judged the time measurement operation is started by the timer, and by judging the absence and rough body movement the time measurement is reset.  It is judged that the body on the bedding has fallen asleep when the measurement time of the timer exceeds a set time predetermined.

Granted: 2002-12-31
Abstract: A method of and system for paging mobile stations within a cellular telecommunication system wherein the allocation of control channel paging capacity is optimized. Each page request for a mobile station received by the system is classified into a predesignated group based upon the characteristics of the request, such as the degree of certainty with which the location of the mobile is known and the origin of the page request. In accordance with the predesignated group to which the page request is assigned, each page request is assigned a paging extent designation to be associated with one or more page attempts and representing the geographic area within the system to which each page attempt is to be broadcast. A paging priority is then assigned to each page attempt based upon the previously assigned group characteristics and paging patterns. Each page attempt is executed within the system according to its designated priority.
