Abstract: Object It is to provide a measured vital data preserving and providing system for healthcare, making it unnecessary to have an independent data base which requires a lot of time and a lot of cost for its preparation, and on the other hand, enabling to construct a unique website for healthcare in a short time and at a low cost. Means for Achieving the Object A data providing side server 30 comprises a measured vital data DB50 composed of measured vital data records including user's IDs and user's measured vital data, and an API library 60 for processing the measured vital data DB50.

Abstract: An optical sensor includes a light transmitter for transmitting pulsed light signals and a light receiver for receiving them. In order to suppress the effects of interfering noise light, the light signals are transmitted according to a specified pattern including pulses in packages separated from each other by a specified interval, the pulses within each of the packages following one another with a specified carrier frequency. Groups each including two or more such pulse packages may be employed. The light receiver converts a received light signal into an electrical signal and directly thereafter passes the electrical signal through a bandpass filter with a pass band including this carrier frequency.

Abstract: A control unit (38) provided on each of a plurality of operating units for integrating the whole of such an operating unit group that operating units performing a certain operation plurally aggregate and making the same perform regularly operation control includes a signal transmission part (33 and 34) and a signal receiving part (35 and 36) for communicating with the adjacent operating unit, and a connection determination part (37) determining whether or not it is located on a predetermined start position forming a start point of integrated control in the operating unit group on the basis of relative positional relation obtained as a result of performing a communicating operation for deciding the operating unit as a master operating unit when determined as located on the start position while deciding it as a dependently operating slave operating unit when determined as not located on the start position.

Abstract: A device for measuring the speed of an object. The device includes a spatial filter scheme to provide quick-response photodetectors and an efficient use of light. The device projects light onto the object by a light source 1, and the light reflected by the object is received by a lens. This light passes through aperture stop 4 and strikes prism array 7, where it is split alternately into two paths at a fixed pitch with respect to the optical axis. The two split beams are received respectively by two photodetectors. The speed of the object moving relative to the measuring device can be calculated based on the data collected by photodetectors.

Abstract: A raindrop sensor of the present invention including light emitting part which emits a strip-shaped light; light receiving part which receives the strip-shaped light emitted from the light emitting means; and detecting device which detects a raindrop based on the amount of the light received by the light receiving device. The raindrop sensor of the present invention is applied to a wiper apparatus of a vehicle. The wiper apparatus includes a wiper for wiping a windshield of the vehicle, and a control unit for instructing a given wiper operation to the wiper in accordance with a given output signals from the raindrop sensor, the wiper being driven in accordance with the instruction from the control unit. Also, the wiper apparatus using the raindrop sensor is applied to a vehicle.

Abstract: Light is projected upon a road surface (LD) from a light source (11) for illuminating the road surface. Diffuse reflected light from the road surface (LD) is received by light sensors (31A, 31B) through a spatial filter, and the resulting light-reception signals are applied to a differential amplifier circuit (51). A center-frequency component corresponding to the spatial frequency of the spatial filter is extracted by a tracking band-pass filter (52), and the intensity (Da) thereof is detected by an amplitude detector circuit (54). Low-frequency component intensity (Db) corresponding to a spatial frequency lower than the spatial frequency of the spatial filter is detected by a tracking low-pass filter (55) and an amplitude detector circuit (56). The condition of the road surface is judged to be snow, gravel or asphalt in a discriminating circuit (60) based upon the center-frequency component intensity (Da) and the low-frequency component intensity (Db).
