Title: Radio terminal
Inventor: WATANABE MITSUHIRO
IPC: H04W40/34
Filed: 2001-11-15
Abstract: PROBLEM TO BE SOLVED: To obtain a radio terminal capable of retrieving an optimum route necessary for communication in a short time of period, in a local network such as an and hoc network. SOLUTION: Respective radio terminals 111 to 118 constituting the local network set a bit error rate and a transfer speed between radio terminals adjacent to each other and calculate a route weighting value about a link between radio terminals, respectively on the basis of the set bit error rate and transfer speed. If a certain radio terminal sets a route to communicate with another radio terminal, the certain radio terminal issues a route retrieval command with a route weighting value as reference to notify the adjacent terminal of the route weighting value. The adjacent terminal propagates a route retrieval command in a similar manner, and however, the adjacent terminal sequentially adds route weighting values at this time.  The opposite radio terminal for communication determines an optimum route from added route weighting values and returns the optimum route to the starting point side.

Title: Method and circuit for driving electrooptic device and electrooptic device and electronic equipment
Inventor: IIZAKA HIDETO
IPC: G09G3/20
Filed: 2001-11-30
Abstract: PROBLEM TO BE SOLVED: To increase remarkably the number of gradations without increasing the number of sub-fields in one field. SOLUTION: In this electrooptic device, the control unit of display is made to be a control unit which drives pixels by dividing one field into a plurality of sub-fields on a time base. The response speed of liquid crystal is slow and the saturation response time is longer than a sub-field period. As a result, even when an ON voltage is applied to the liquid crystal, for example, only in one prescribed sub-field, transmissivity of the liquid crystal does not reach 100%. Namely, in the transitional period of the transmissivity of the liquid crystal, it is possible to control finely the change of the transmissivity in one sub-field. Thus, display in multiple gradations is possible on the device since the number of gradation can be remarkably increased as compared with the number of sub-fields in one filed.
