  • Publication number: 20190299743
    Abstract: An occupant detection system may detect a state of an occupant in a vehicle compartment. The occupant detection system may photograph the vehicle compartment and generate an image. The occupant detection system may change an attitude in order to change a position of an imaging region within the vehicle compartment. The occupant detection system may estimate the attitude based on information included in the image and control an operation based on the estimated attitude. The sensor may be provided by an infrared temperature sensor. The image may be provided by a thermal image showing a temperature distribution of the vehicle compartment. The occupant detection system may store a correspondence relationship between a position of a specific temperature boundary included in the thermal image and the attitude. The occupant detection system may estimate the attitude based on the correspondence relationship.

  • Publication number: 20190267916
    Abstract: An actuator that comprises a deformable material, an energy input part, and a characteristics change detection unit. The deformable material is configured with a polymer fiber and, by deforming in response to energy input from the outside, outputs motive power. The energy input part inputs energy to the deformable material. The characteristics change detection unit detects when the deformation characteristic of the deformable material has changed. The actuator also comprises a drive control unit that, by controlling the above-described energy, controls the output of the deformable material. When the characteristic change detection unit detects a change in the deformation characteristic, the drive control unit controls the energy in accordance with the change in the deformation characteristic.

  • Publication number: 20190214924
    Abstract: An actuator device includes an actuator member, a drive subject, a drive device, and a tension applicator. The actuator member is configured to be deformed in response to application of energy to the actuator member from an outside of the actuator member. The drive subject is coupled to the actuator member. The drive device is configured to apply the energy to the actuator member and thereby displace the drive subject in a deforming direction of the actuator member. The tension applicator is configured to apply the actuator member a tension, which enables correction of a tension change generated by at least one of elongation and contraction of the actuator member that is induced by natural deformation of the actuator member.

  • Patent number: 7881037
    Abstract: An air bag device of the present invention includes squibs and a capacitor, an electric discharge circuit as well as a backup power supply, a voltage stabilizer and ignition circuits. The voltage stabilizer converts the voltage of the backup power supply to the predetermined target voltage, and the converted voltage is supplied for the ignition circuit. The capacitor removes a noise emitted by the ignition circuit. The electric discharge circuit discharges electricity accumulated in the capacitor right after the supply of an ignition current from the ignition circuit has ended. In this manner, a voltage rise of the capacitor occurring after the end of the supply of the ignition current can be resolved immediately, thereby enabling a supply of a stable ignition current for the squibs.

  • Patent number: 7579880
    Abstract: A drive circuit is provided for driving a voltage-driven semiconductor element by producing a drive signal depending upon an input signal. The drive circuit comprises an output stage and a current-suppressing circuit. The output stage includes two semiconductor elements connected in series. The voltage-driven semiconductor element is connected to a common connection point of the two semiconductor elements. The current-suppressing circuit controls one of the two semiconductor elements to provide an output current flowing through either one of the two semiconductor elements if a voltage applied to the voltage-driven semiconductor element reaches a limit level, which is in excess of a level for conducting the voltage-driven semiconductor element by a predetermined voltage.

  • Patent number: 7176669
    Abstract: In a frequency modulation type switching regulator for producing an output voltage to a load, an error amplifier produces an error voltage indicative of a difference between the output voltage and a reference voltage. A switching device is turned on and off at a switching frequency corresponding to the error voltage. A voltage-frequency modulation circuit monitors an operation condition of the load. The modulation circuit generates a varying voltage, which varies around the error voltage, when the monitored operation condition is substantially unchanged. The switching frequency is switched to another frequency corresponding to the varying voltage, so that noise level may be reduced.

  • Patent number: 7167153
    Abstract: When power is turned on, dummy output information stored in a non-volatile memory is issued to the digital signal processing circuit. In a dummy data processing block, and in a line memory holding data in the horizontal direction, dummy data inputted from outside is inserted into a one-line video data processed at an input signal processing block, based on the dummy output information. In this way, the video data is revised into data that is appropriate for each display, based on the dummy output information. Then the one-line video data including the dummy data is inputted into the output signal processing block, and is latched by the output signal processing block, and outputted to each of the data drivers as a data driver output signal, at the same time.

    Abstract: A semiconductor integrated circuit device for a power source capable of being expanded to cope with an increase or decrease in the load includes an outer transistor attached to the outer side of an IC, and a transistor incorporated thereon simultaneously operated to enhance the current output capability of a linear regulator when a load is great. A control circuit controls the transistor to produce a constant voltage, and controls the outer transistor to control the current ratio of the current flowing into the transistor and the current flowing into the outer transistor. An over-current detecting circuit detects, at one time, the collector currents of the transistors flowing into the output line, and executes an over-current protection control based on the detected values.

An input signal and an output signal are coupled to one side and to the other side of a current mirror circuit. The input signal is sample-held by a differential circuit adapted to cause the current to flow a desired current to the current mirror circuit and to perform switching of the current mirror circuit and sample clocks entered to the differential circuit. The sample-holding operation is feasible even with a lower voltage source.
