Abstract: Apparatus and method for measuring the weight of an object such as a letter, magazine or parcel, while the object is in motion, without using a weighing scale. The apparatus and method disclosed make use of moving, preferably vertically-oriented transport belts driven by a constant velocity, closed-loop feedback system which includes an electric motor. An object to be weighed is engaged and lifted upwards by the moving belts, increasing the load on the motor as a function of the weight of the object. The increased motor current evoked by the lifted object can be processed to extract the object's weight.

Abstract: A control system for a bi-directional shuttlecar having a loading end and a discharge end. A conveyor extends along the shuttlecar from the loading end to the discharge end, and a pressure sensing transducer is located at the loading end and an independent pressure sensing transducer is located at the discharge end. The pressure sensing transducers are connected in an electric circuit with programmable logic controller which also includes a drive motor for the conveyor and a controller for the drive motor. The weight of mined material supported on the conveyor at the loading end of the vehicle is sensed by the pressure sensing transducer at the loading end and creates a signal for transmission to the programmable logic controller to start the movement of the conveyor and the weight of the mined material at the discharge end of the vehicle is sensed by the pressure transducer at the discharge end and creates a signal for transmission to the programmable logic controller to stop the movement of the conveyor.

Abstract: An object of the present invention is to accurately measure a carrying weight of a vehicle on the basis of a force applied to suspension cylinders and allow an operator to accurately recognize the weight. A first force applied to a front wheel suspension cylinder of a vehicle carrying a load can be obtained on the basis of detection values of pressure sensors (2a, 3a, 2b, 3b), and a second force applied to a rear wheel suspension cylinder can be obtained on the basis of detection values of pressure sensors (2c, 3c, 2d, 3d). An inclination O of the vehicle in the longitudinal direction is detected by an inclinometer (8), and the first and the second force are corrected in accordance with this inclination O. Further, the first and the second force are corrected in accordance with the magnitudes of the first and the second force to thereby obtain the weights of the vehicles on the front wheel side and the rear wheel side.

Abstract: The invention is a load cell for the measurement of force, independent of displacement, created by means such as weight, acceleration, pressure, and the like. The load cell has a beam structure with beams positioned parallel to each other in at least one plane. Generally, these parallel beams are attached to a stationary base and have sensing means attached between the two beams. In operation, deflection of one beam creates a response in the sensing means due to the relative action or deflection in the second beam.

Abstract: There is disclosed a thermal printer system having a multiple channel laser print head which focuses closely spaced spots of laser light energy onto a dye donor element which moves at constant velocity relatively past the print head. These laser light spots respectively print multiple lines of an image a swath at a time by heat transfer of pixels or subpixels of dye from the dye donor element to a receiver element. A light source (such as an arc lamp) applies to the dye donor element one or more precisely positioned spots of light energy which elevate the temperature of the dye donor element substantially uniformly within a zone coincidently with and closely surrounding the laser light spots. The shape, the position and the power absorbed within the zone from the light source are carefully controlled. Thus the temperature within this zone is held to a substantially uniform value slightly below the vaporization temperature of the dye to be transferred from the dye donor element.

Abstract: An ink jet printing device has a drop generator for producing continuous streams of ink drops from at least one orifice and further has stimulation control electronics for maintaining desired stimulation conditions in response to a feedback from the drop generator. First and second feedback transducers measure the stimulation amplitude in the drop generator and generate feedback output signals in response to the stimulation. The feedback output signals are approximately equal in magnitude and opposite in sign to each other when the stimulation amplitude in the drop generator is a desired stimulation mode. An amplifier, whose inputs are the feedback output signals, provides an amplifier output signal to the stimulation control electronics which is the difference between the two feedback output signals.

Abstract: A mobile apparatus and method for weighing bales on an electronic scale in a field. Fixedly supported on the rear end of a mobile crop baler are two load cells from which is pivotably suspended the inboard end of a bale-receiving-structure. The outboard end of the bale-receiving-structure is adjustably supported by a tether from at least one other load cell fixed to a rearwardly extended portion of the baler which allows the outboard end to swing upwardly as the underside of the bale-receiving-structure encounters berms in the field thereby preventing damage to the electronic scale components. The weight of each bale produced by the baler is digitally readout in the baler cabin where, by comparison to a predetermined weight, real time adjustments are automatically or manually made to adjust bale weight to the predetermined weight, thereby achieving greater weighing accuracy and enhanced overall output from the field. The scale may be used on original equipment balers or made to retrofit existing balers.

Abstract: An in bed infant scale for use with an infant care center and which may be slid underneath the infant platform of the infant care center while the infant is positioned within the center and which causes little disruption to the infant. The infant scale is thus movable from infant care center to infant care center conveniently. The infant scale is easily slid into the infant care center and raises the infant platform on which the infant is positioned such that the infant platform is raised off of its position on its supporting frame and becomes fully supported on the infant scale. Thus the infant scale can weigh the infant platform and the infant resting on that infant platform.
