Abstract:
A seat-load measuring device for measuring a weight of a passenger and an object sitting on a car seat includes a load sensor disposed under the seat for electrically sending load data, a first data processing unit having a predetermined response time, a second data processing unit having a slower response time than that of the first data processing unit, a detecting device for detecting a change in the load data, and a switching device electrically connected to the detecting device. The first and the second data processing unit switch between the first and the second data processing unit to process the load data from the load sensor.
Abstract:
A seat load measuring apparatus that can provide an accurate load output even when one or more sensors are exerted with a load in excess of its measurable load is provided. In a first instance, the output of each load sensor is read at Step S11. Subsequently, at step S12, whether or not there is any sensor whereof the output is in excess of the predetermined value is determined. If no output of these sensors is in excess of the predetermined value, it is regarded as normal, and the seat weight is obtained by summation of the outputs of the sensors at Step S13. When the output of any sensor exceeds the predetermined value, it is determined that an offset load is exerted thereon and thus the output of the sensor in question cannot be trusted. Therefore, the seat weight obtained immediately before the output of any of the sensors exceeds the predetermined value is regarded as the seat weight.
Abstract:
To provide a seat load measuring device which is capable of reducing production cost and assembly cost and which makes it possible to measure the weight of the person on the seat more accurately. The device measures the load of a seat of a passenger vehicle (including the load of an object placed on the seat), wherein the load of the seat is received at three positions, the load being put together in a load cell and transmitted through a transmission mechanism, load measurement being performed by a load cell or a load measurement plate.
Abstract:
A vehicle collision damage reduction system is provided. The system works by detecting the relative speed between the vehicle and an object, such as another vehicle. A danger level is calculated based on parameters such as speed and distance to the object; the danger level could be at an “emergency level” or at some lower level. Based on the danger level, different corrective measures and the degree of the corrective measures can be adjusted to attempt to minimize occupant injury. For example, the airbag can be adjusted to better protect the occupant, a pre-tensioner can be activated at a certain level, and the inclination of a child restraint seat may be adjusted as well.
Abstract:
To provide a seat weight measuring apparatus capable of estimating with higher precision the weight and the center of gravity of a passenger on the seat and with reduced cost, a seat weight measuring apparatus is provided. The seat weight measuring apparatus comprises a load cell, a connecting mechanism, which connects a seat and the seat fixing portion of the vehicle body, and a transmitting mechanism which transmits the action of the seat weight on the connecting mechanism to the load cell. In the transmitting mechanism and the connecting mechanism, arms are pivotally supported by horizontal pivots so that the arms can pivot about the pivots. Actions according to the pivotal movements of the arms are transmitted to a load cell. Loads on the front side portion and the rear-side portion of the seat are each measured by one center load cell.

A moisture curable composition excellent in transparency, operating efficiency and storage stability, and is suitable for use as an adhesive and a sealing material is provided. The moisture curable composition produced by blending 100 parts by weight of a mixture (A) and 2 parts by weight to 300 parts by weight of amorphous powder (B). The mixture (A) comprises (1) a copolymer having reactive silicon groups which can be cross-linked by hydrolysis, whose molecular chain substantially consists of (i) alkylacrylate and/or alkylmethacrylate monomeric units having an alkyl group with 1 to 8 carbon atoms, and (ii) alkylacrylate and/or alkylmethacrylate monomeric units having an alkyl group with 10 or more carbon atoms, and (2) a polymer substantially consisting of oxyalkylene including reactive silicon groups which can be cross-linked by hydrolysis. The amorphous powder (B) has a grain diameter ranging from 0.01 &mgr;m to 300 &mgr;m.
Abstract:
A seat weight measuring apparatus that simplifies the circuit configuration of the load sensors to reduce the circuit costs and which, when the load sensors fail, immediately detects the failure of the load sensors, thereby improving the reliability. In the case where four load sensors are arranged at four locations, for example front and rear on both sides, of the bottom of the automotive seat, the seat weight measuring apparatus includes two pairs of load sensors, a detection circuit for detecting a difference between outputs from the two antiphase-connected pairs of load sensors, and a seat weight calculator for calculating the weight of the automotive seat based on an output from the detection circuit. This can simplify the circuit configuration and eliminate problems of circuit costs and reliability.
Abstract:
A stairway lift is provided on the treads of a stairway along a sidewall. A guide of the lift is provided on the treads along the sidewall so that a space is formed between the sidewall and the guide. The guide has a first side that faces the sidewall, a first rail provided on the first side, a chain rack on the first side that extends along the sidewall and a second side that faces away from the sidewall. A mobile body is supported by the first rail in the space formed between the sidewall and the guide. The mobile body has a drive sprocket engageable with the chain rack and an electric motor coupled with the drive sprocket for rotatively driving the drive sprocket. A carrier is provided for carrying a person or object to be moved along the stairway. A coupling arrangement couples the mobile body and the carrier so that the carrier is removably supported by the mobile body on the second side of the guide and guided for travel by the guide. The carrier can thus ascend and descend the stairway together with the mobile body.
Abstract:
In an image forming apparatus for forming a static latent image using ions as a medium, an ion generation formed by stacking a plurality of line electrodes, a plurality of finger electrodes, and a screen electrode with dielectric layers being sandwiched therebetween is arranged to oppose a dielectric drum on which the electrostatic latent image is to be formed. A static induction transistor for switching an RF high-voltage signal at a high speed is connected to each line electrode of the ion generator. Each static induction transistor is also connected to a DC high-voltage power source via a coil. When each static induction transistor is driven at a high frequency by a source drive circuit, an RF high voltage is applied to a corresponding line electrode. A voltage is supplied to a parallel resonator constituted by the coil and a line electrode capacitance to start resonance, thereby obtaining an output for ion generation.
Abstract:
In a method of manufacturing an optical waveguide by the use of a substrate which has a first ion of a first refractive index and primary and secondary surfaces, an optical passage is formed in the substrate by diffusing through the primary surface a second ionizable species of a second refractive index greater than the first refractive index. A diffusion-accelerator layer is deposited on the secondary surface to accelerate diffusion of secondary ions resulting from the second ionizable species. To this end, the diffusion-accelerator layer is composed of an additional ionizable species which is formed into additional ions able to react with the first ions. Such reaction of the additional ions with the first ions lends itself to reduce the amount of the first ions in the substrate and to promote diffusion of the second ions into the substrate.
