Title: Assistance system for crossing pedestrian of pedestrian crossing
Inventor: KANEKO TOMOYUKI
IPC: G08G1/01
Filed: 2000-12-06
Abstract: PROBLEM TO BE SOLVED: To pay vehicle-driver's attention by generating a secure alarm when a pedestrian crosses a pedestrian crossing having no traffic signal, to keep the crossing pedestrian on his or her guard by not informing the crossing pedestrian of the alarm contents, and to enable the pedestrian to cross the pedestrian crossing safely at low cost. SOLUTION: When the crossing pedestrian enters a crossing pedestrian detection area 18a in order to cross the pedestrian crossing 16 having no traffic signal, a pedestrian detection sensor 18 detects the presence of the crossing pedestrian and sends a detection signal to a controller, so that notice lamps 28, 30, 32, etc., arranged nearby the pedestrian crossing 16 are controlled to illuminate. The projection lights from the notice lamps can not be recognized by the crossing pedestrian because of the structure, but can be recognized from passing vehicles, so that driver's attention can be attracted while the crossing pedestrian is kept on his or her guard. Consequently, the pedestrian is made to cross the pedestrian crossing having no traffic signal safely at low cost and the pedestrian is not kept waiting for longer than a necessary time.

Title: Collimator controlling method, x-ray ct equipment, ratio arithmetic method and bit number adjuster
Inventor: BESSHO KOJI
IPC: A61B6/03
Filed: 2000-12-07
Abstract: PROBLEM TO BE SOLVED: To control a collimator so that the width of an X-ray beam entering the respective detector string of a multi X-ray detector may become a prescribed ratio. SOLUTION: Data XA and XB outputted from a reference channel are measured, respectively, a value Y decided by the ratio of the data XA and XB is calculated and the position of the collimator is moved so that the value Y may be '0'. When a maximum value in the data XA and XB is expressed by the first bit to the K-th bit and is K>8 when the data XA and XB are 24 bits and the number of the bits of an arithmetic unit for calculating the value Y is 8 bits, the (K-7)-th bit of all the data to the K-th bit is taken out to calculate the value Y. In the case of K<=8, the first bit of all the data to the eighth bit is taken out to calculate the value Y. Consequently, a time for processing can be reduced. An inexpensive processor of the reduced number of bits can be used.
