Abstract: An answer totaling and analyzing apparatus according to the present invention possesses an auxiliary light-projecting and receiving unit relaying a light-emitting and reception between a center unit and answer units, in addition to the center unit and the answer units exchanging signals by optical pulses. The center unit assigns answer periods of the respective answer units by answer command signals for the plural answer units. The respective answer units can reply answers for questions with a very small number of pulses by using a method in which contents of the answer are represented by a time position of an optical pulse transmission in the answer period assigned to the answer unit. The center unit discriminates the answer signals from the respective answer units by this communication method and detects the answer and totalizes and analyzes the answer.

Abstract: This invention is concerned with an apparatus for totaling and analyzing replies for totaling and analyzing replies to presented questions at meetings and conferences. The purpose is make setting and removing easier expand its use by changing known apparatus for totaling and analyzing replies to wireless diminishing wired connection between replying unit and center apparatus. In this invention, each of replying units has its identification code, and a space transmitting infrared light is used for communications between replying units and a center apparatus. Replying signals from the replying units are sent at each replying period designated to each replying unit by the identification code obeying a command signal from the center apparatus. The center apparatus recognizes the code of the replying unit, which sent signals for received replying signals from the timing of the signal and uses for totaling and analyzing.

Abstract: In a course guidance system for use in an automobile, for example, which includes an electronic display, a map, a direction sensor, a speed sensor and the like for deriving the present location of the car and plotting it on the display, the invention provides a course guidance system for a car which causes a linear and/or rotational movement of the driving locus displayed on the display when the map is changed or reset so that the present position can be easily located on the map.

Abstract: A course guidance system includes a direction sensor and a speed sensor both fitted to a moving body, a display mounted in the moving body and a map displayed in a manner corresponding to the display surface of the display and in which the present position of the moving body is derived by the direction sensor and the speed sensor and is plotted on the display in a manner corresponding to the map.

Abstract: A structure for mounting a seat belt anchor for a vehicle with a sliding door includes a reinforcement member disposed within a vehicle side frame and adapted to receive a curved end of a guide rail from which the sliding door is slidably suspended. The reinforcement member is secured to the side frame with a fastener bolt. An anchor of the seat belt is also secured to the side frame with a fastener bolt also used to secure the reinforcement member. The reinforcement member provides the side frame with sufficient structural strength to resist bending moment applied via the seat belt.
