A brake operating device in which an operation of a brake pedal can be detected easily by a simple structure is provided. The brake operating devicecomprises: a pusherconnected to a brake pedal; a hydraulic systemin which fluid is held between the pusherand a pushing elementto transmit a thrust force of the pusherto the pushing element; a first elastic mechanismthat establishes an elastic force to isolate the pusheraway from the pushing element; a cylinderholding the pusherwhile restricting a withdrawal limit of the pusherin a direction away from the pushing element; and a second elastic mechanismthat is arranged at a position to push the cylinder, and that establishes an elastic force against the elastic force in the direction to isolate the pusheraway from the pushing element

Brake operating device

A pedal stepping force detector includes a rod, a case having a bottomed-cylindrical shape and extending along a longitudinal direction of the rod, a strain body housed in a bottom portion of the case, an operating body that is housed in the case so that the operating body is in contact with the strain body, and an elastic member that is compressed in association with an operation of the rod and thus causes biasing force to act on the operating body

Pedal stepping force detector

A storage unit for an occupant detection system detecting an occupant based on a magnitude correlation between a detection load value obtained by a load sensor and a threshold value, the storage unit includes a first ROM storing either one of the threshold value and a threshold value specific information for identifying the threshold value, the first ROM being rewritable and a second ROM storing information except for either one of the threshold value and the threshold value specific information, a rewriting of the second ROM being more difficult than a rewriting of the first ROM.

Storage unit for occupant detection system

A terminal control system is provided that has a main control device, a plurality of terminal devices controlled by the main control device, and communication lines for connecting the main control device and each of the terminal devices so as to allow bidirectional communication, wherein the configuration is simple, communication time is short, and highly reliable bidirectional communication is possible. The terminal control system comprises a main control device, a plurality of terminal devicescontrolled by the main control device, and communication linesfor connecting the main control device and each of the terminal devices so as to allow bidirectional communication, wherein control data is simultaneously and collectively sent from the main control deviceto a plurality of the terminal devices, and terminal data for each of the terminal devices is independently sent from each of the terminal devicesto the main control device

Terminal control system

An information request portion receives an information request signal transmitted to an information response portion at its own receiving port. The information request portion comprises at least either of a power supply system anomaly determination portion or a ground anomaly determination portion. The power supply system anomaly determination portion determines a short-circuit between a signal line and a power supply system in a case where the information request signal received at the receiving port is always fixed to a H (high) level. The ground anomaly determination portion determines a short-circuit between a signal line and a ground in a case where the information request signal received at the receiving port is always fixed to a L (Low) level. Consequently, the anomaly region of the signal line connecting the information request portion and the information response portion in such a manner that bidirectional digital communications are possible or the cause of the anomaly is specified.

Communication anomaly detecting device, and passenger detecting device

An occupant load sensor of a seat for a vehicle includes a metal-made bracket fixed to a strain member and having an attachment portion extending in a lateral direction from the strain member, an amplifier substrate for amplifying a signal transmitted by the strain gauge. One surface of the amplifier substrate is covered by the attachment portion of the metal-made bracket and the other surface thereof is covered by a metal-foil ground pattern. The occupant load sensor further includes a resin-made amplifier case fixed to the attachment portion of the metal-made bracket and arranged in parallel to the strain member. The resin-made amplifier case houses therein the amplifier substrate.

A load detecting device includes a plurality of load sensors which are disposed in a matrix shape and correcting means for setting at least one of the plural load sensors as a standard load sensor and for correcting level of output values of each load sensors to level of output value of the standard load sensor on the basis of the output values of each load sensors.

Load detecting device for a vehicular seat

In a passenger weight measuring apparatus, each of bend parts of front and rear brackets for supporting a seat to a vehicle main body side becomes bent and deformed in response to the load applied by the weight of the passenger sit in the seat. A load sensor on each the bend part detects the load based on the bend deformation and outputs a voltage signal of magnitude responsive to the load to a signal processor. The processor generates a load detection signal clamped in the voltage range corresponding to a preset passenger weight load range from the voltage signal and outputs the load detection signal to an output terminal. When the detected load is a collision load set in a load region out of the load range, the processor outputs an abnormal load detection signal different from the load detection signal to the same output terminal.

Passenger weight measuring apparatus

A printed circuit board having electrical components connected thereto in spaced relation is coated with a resin material by immersion in a container of resin material. The flow of resin between the electrical devices and the circuit board is facilitated by the provision of holes through the circuit board in alignment with each electrical component so that the formation of blow-holes is prevented.
