Abstract: A spring has a fixed end and a free end. A specific portion of the free end is elevated from the fixed end, and a load measuring device that measures the load on the spring is arranged so as to make a physical contact with the free end. An elevation is measured from the fixed end of a specific portion of the load measuring device where the free end and the load measuring device make the physical contact with each other. It is determined whether the elevation measured is equal to a specific elevation and the load on the spring is measured with the load measuring device when the elevation measured is equal to a specific elevation.

Abstract: There can be obtained a handlebar stem ensuring that a speed indicator provides a readily observable indication and in addition thereto capable of achieving a reduction in size and weight. A handlebar stem attaching a bicycle's handlebar includes a rod attaching the handlebar stem to the bicycle; a speed indicator receiving a signal from a speed sensor to display speed; and an indicator housing located at a front protrusion extending in a forward direction to traverse the rod to house the speed indicator, the indicator housing, as seen along the rod, overlapping or being adjacent to the rod.

Abstract: An occupant weight sensor (1) for placement between a frame (7) fixed to the chassis of a vehicle and a second frame (8) supporting a vehicle seat has a sense element having a first body (12, 22, 28, 34, 50, 62, 64, 68, 84) formed with a planar sense surface on which are mounted piezoresistors electrically connected in a Wheatstone bridge configuration. A post (12a, 22c, 28c, 34e, 50b, 62a, 64a, 68b, 84g) extends outwardly from the first body for attachment to the first frame. A second body is formed with a force transfer portion (14a, 24g, 30d, 36b, 52a, 70a, 94a) permanently attached to the first body along an outer periphery circumscribing the sense surface. The piezoresistors are electrically connected to conditioning electronics received in a chamber formed between the two bodies. The effects of parasitic loads on the sense element are minimized by selected placement of the piezoresistors on the sense surface.

Abstract: A seat weight measuring apparatus includes a base frame and a sensor portion which is mounted on the base frame and configured to detect a load applied to a vehicle seat. The sensor portion includes a sensor plate provided with a plurality of measuring gauges, and the sensor plate is supported by and fixed to a column disposed on the base frame. The seat weight measuring apparatus has a heat transmission route through which heat transmitted to the column is directly transmitted from the column to the sensor plate. Further, the seat weight measuring apparatus includes, between the sensor plate and the column, a heat transmission bypass through which heat transmitted to the column is transmitted to the sensor plate to bypass the heat transmission route.

Abstract: A printed circuit board (PCB) having an integrated strain gage. In one embodiment, a PCB includes a component footprint suitable for mounting an electronic component. A strain gage is integrated into the PCB in a location under the component footprint. The strain gage includes at least one electrical conductor that is accessible for resistance measurements.

Abstract: This invention relates to a mobile measurement system of three-dimensional structure comprises a measuring equipment 5 to measure three-dimensional structure of an object for measurement and a barrow 4 for moving measurement which the equipment 5 is mounted. The measuring equipment 5 has a digital camera 5a, a slit floodlight 5b, and a three-dimensional structure calculating device that calculates and outputs three-dimensional structure of the object by using a light plane range-finding method from the each position and direction of the floodlight and the camera and the picture that is taken by the camera.

Abstract: A removable twisting measuring device for various hand tools comprises a cover removably installed on a rod body of a hand tool; a strain gauge installed at one end of the cover contacting the rod body of the hand tool; the strain gauge having a deformation due to a twisting force; a display device having a transfer element; resistance variation due to the deformation of the strain gauge being transferred to the display device so as to derive the twisting force which is then displayed on the display device. The display device can be installed to another removable covers. Moreover, outlooks of the covers are matched to the hand tool. The cover is made from one of aluminum alloys and deformable materials. The display device has a screen and a calibrating button.
