摘要： An automotive seat includes optical sensors for determining a load on the seat, such as a person. The sensors may be used with a computer and computer software to analyze data from the sensors in determining a weight of the load, and the sensors may also be used to determine a shape of the load. From the weight and shape of the load, the computer may decide whether the load is suitable for safe deployment of an automatic restraining device, such as an airbag.

摘要： For measuring the weight of a load of a load-carrier of at least one vehicle, which load-carrier is supported by at least one spring unit on a mobile substructure of the vehicle, weighing apparatus is provided with means for measuring the elastic deformation of the spring unit or units under the load. The measuring means includes a reference object mounted on the load-carrier. To avoid vulnerable equipment on the vehicle and to improve information obtained, the measuring means includes electrical observation means for non-contact observation of the position of the reference object. The electrical observation means being free of the vehicle.

摘要： An optical detector for a weight measuring system senses the relative movement between a frame and a load support of a scale assembly. The detector includes a transducer subassembly which carries a plurality of photodetectors positioned at the end of a light path which is modulated by a pair of optical gratings. One of the gratings is fixed relative to the scale frame, and the other is mounted to the load support assembly in alignment with the fixed grating. Placement of a load upon the scale deflects the load support to provide an optical signal including a cyclic pattern of light to dark transitions which is detected by the photodetectors. Optical compensation for nonlinearities in scale load support deflection which are inherent with the scale assembly is provided by generating an optical signal which indicates displacement different from the vertical component of deflection. Such compensation is provided by establishing a predetermined grating angle relative to a horizontal plane.

摘要： A system for processing cyclic signal pairs generated by an optical transducer to provide an accurate measurement of the displacement of one member with respect to a reference is suitable for determining weight by measuring spring scale tare deflection. The system includes a pair of comparator Schmitt trigger circuits for shaping pulse waveform signals. The pulse signals are processed by fully clocked digital circuits including edge discriminators to generate multiple count pulses which are processed by combination logic for direction determination. Further processing includes sign determination (positive-negative) and zero identification circuits to provide up and down pulses which are filtered and fed to up/down counter stages. Counter stage information is decoded for feedback control and processing logic indication. The zero identification circuit facilitates an unambiguous zero reference indication by skipping one count at zero to provide a display sign change indication on either side of zero prior to incrementing display counts to better define true zero as an edge or line between successive displays rather than as a zone. In an alternate embodiment, zero transition indicators are provided by feeding the count pulses directly to an updown counter and utilizing the most significant counter bit to invert the counter outputs upon a transition through actual zero.

摘要： A weighing scale includes an optoelectronic system having apparatus for generating a moire fringe pattern and for detecting the moving of the pattern in accordance with scale tare deflection. One of a pair of ruled parallel grating sets is fixed with respect to the scale frame while the other is mounted for movement with the tare and close to and in a plane parallel with the fixed set. When a beam of light is projected through both grating sets in a transmissive mode towards a photodetector array the grating interference modulates the light beam into parallel moire fringes. Upon placement of a load on the scale, deflection of the tare results in movement of successive fringes across the photodetectors resulting in the sequential generation of weight indicative signals. The photodetectors are arrayed on and secured to a movable carrier which is adjustably positionable so that the effective spacings between the photodetectors corresponds to the spacings and proper phase angle required between said fringes.

摘要： Weighing apparatus for grading articles such as eggs and the like according to their weight. The apparatus comprises a tray, and a pair of leaf springs for mounting the tray for up and down movement and operatively connected to the tray and a support member, and being deflectable generally downwardly relative to the support member a first distance responsive to article weight. A stop is provided for allowing downward deflection of the tray relative to the support only to a second distance, which is normally less than the first distance. An out-of-round cam or the like changes the relative position of the stop and the support member so that the second distance approaches the first distance, and electrical contacts, photoelectric apparatus, or the like, are provided to sense when the second distance is substantially equal to the first distance.

摘要： A parallelogram linkage transmits the displacement of the weighing platform to a bridging arm from which the movable member of a precision displacement measuring device is suspended. This movable member is guided in a linear path in a fixed member in which adjustable screws are provided on each side of the movable member to reduce the play of the movable member in its linear path to a minimum, without introducing any appreciable amount of friction. The movable and fixed members each carry a grating and a photoelectric detector produces pulses in response to relative movement of the gratings which are counted and displayed electronically.
