    Abstract: A motion conversion system is described. The motion conversion system comprises a first torsional member operative for rotating in a first direction. A second torsional member is offset a distance from the first torsional member, wherein the second torsional member is operative for rotating in a direction opposite from the first direction. And, a lateral member has a lower surface connected to the first and second torsional members. Wherein, translational movement of the lateral member results from rotational movement of the first and second torsional members.

  • Patent number: 8175838
    Abstract: In a running test, vehicle wheels are mounted on rollers. Each roller receives torque corresponding to the running resistance, which is a value corresponding to the running resistance applied to the vehicle on actual ground. The actual friction coefficient between the wheels and the rollers is calculated. The running resistance is corrected such that the actual friction coefficient becomes equal to the friction coefficient on actual ground that is calculated based on the slip ratio of the wheels with respect to the rollers. This approximates the running resistance applied to the vehicle by the rollers to the running resistance applied to the vehicle on actual ground as the torque is applied to the rollers in correspondence with the corrected running resistance. This prevents the drive force produced by the vehicle in the running test from becoming different than the drive force that is produced when running on actual ground.

  • Publication number: 20110019373
    Abstract: The invention relates to an arrangement for sensing ambient conditions in electric equipment. These conditions may include verification of the user, the location of the equipment and various properties of the environment. The invention is preferably applied in mobile terminals. One idea of the invention is to provide a sensor arrangement with a substrate (663) that forms at least part of a sensor, and also serves as a substrate for other sensors (695-698). The substrate is preferably flexible so that it can be formed in a shape which is follows the shape of the device cover. The invention also describes a way to create two- or three-dimensional electrode structures that can be used to optimize the performance of the sensor. When the surface structure is designed to follow the shape of a finger, a very small pressure is required when sliding the finger along the sensor surface. This way the use of the sensor is ergonomic and the measurement is made very reliable.

    Abstract: An automotive vehicle has road wheels that are coupled to suspension uprights of the vehicle through wheel ends that have the capacity to monitor lateral loads that act on the road wheels at tire patches where the road wheels contact a road surface. Each wheel end offsets displacements that would be produced within the wheel end by vertical loads with displacements that would be produced by moments induced by the vertical loads, so that the remaining displacements within the wheel end reflect essentially lateral loads exerted at the tire patch. The wheel end contains a sensor and a target that the sensor monitors to detect the presence and magnitude of the displacements and hence the magnitude and direction of the lateral force at the tire patch. The sensor may also monitor angular velocity, angular position, and temperature.

  • Patent number: 7026946
    Abstract: Method and apparatus for identifying and categorizing the weight and characteristics of the occupant currently occupying a vehicle seat. The method for identifying and categorizing the occupant or object involves measuring the deflection of the upper surface of the seat cushion at several points and therefore the weight distribution of the occupant. The system contains multiple weight sensors arrayed for detecting the distribution of the load causing the seat deflection. The system also includes a sensor to measure ambient temperature, preferably for temperature compensation due to the effects extreme temperatures may have on the compression properties of the seat cushion material and the weight sensors. A system processor interprets the data acquired by the sensors, and utilizes an algorithm and weight tables to simulate a neural network in providing an output a control signal indicative of the categorization of the occupant or object.

  • Patent number: 6945126
    Abstract: A rotation sensor functioning as both a rotation-angle sensor and a torque sensor is provided which, when applied to a steering sensor for an automobile, for example, permits reduction in the number of components and thus in the weight of the automobile and contributes to conservation of global environment. The rotation sensor has slip rings covered with conductive synthetic resin having small coefficient of friction, allowing the contact pressure of brushes disposed in sliding contact with the slip rings to be kept low and the life duration of the slip rings to be prolonged. Further, no metal powder is produced when the brushes slide on the respective slip rings, and it is therefore possible to prevent the formation of unwanted insulating film.

  • Patent number: 6938500
    Abstract: An apparatus and method for testing a spindle are provided. The apparatus includes a rotational load device and a linear load device. The rotational load device is connected to the spindle via a shaft and configured to rotationally load the spindle. The linear load device is configured to apply a predetermined linear load on the shaft, so that the linear load is at least partially transmitted to the spindle. The spindle can be subjected to various linear and rotational loads to determine the effectiveness of the spindle, and the performance of the spindle can be measured.

  • Patent number: 6937143
    Abstract: The present invention relates to a vehicle passenger detecting apparatus capable of detecting an unoccupied-seat state through the use of existing signals in a vehicle and correcting an unoccupied-seat reference value with a simple configuration. In a case in which an ignition key switch and a buckle switch are in off conditions and a load detecting value, which is the sum of measurement data from load sensors in these conditions, falls below a predetermined unoccupied-seat load value, an occupied-seat reference value serving as a load measurement standard for detection of a state of a vehicle passenger is corrected using the load detection value. This eliminates the influence of vibrations stemming from engine revolutions and electrical noises and enables the reference value to be corrected using a stabler load detection value.

  • Patent number: 6915708
    Abstract: A device for detecting force acting on a vehicle wheel, is mounted in a vehicle and includes a disc wheel, and a vehicle body having a hub as a retaining body that rotatably retains the vehicle wheel integrally with the disc wheel and in which the disc wheel is mounted on the same axis as the vehicle wheel. The device includes a detector mounted between the disc wheel and the retaining body to receive force that is transmitted between the disc wheel and the retaining body, and which detects force acting on the vehicle wheel. With this device, it is possible to detect force acting on the vehicle wheel without being restricted by either the disc wheel or the hub. Accordingly, this device facilitates highly accurate detection of force acting on the vehicle wheel by optimizing the arrangement, structure, and shape and the like of parts.
