  • Patent number: 6583369
    Abstract: A scale with a transiently visible display includes: an enclosure having an upper surface; a measurement device disposed in the enclosure; and a display coupled to the measurement device and attached to the enclosure beneath the upper surface, the display displaying a measurement value only when the display is an active state. Activation of the measurement device places the display in the active state whereas deactivation removes the display from the active state. The enclosure obscures the display from visibility when the display is not in the active state. Optionally, the scale may include a facade beneath the upper surface and a shutter adjacent the facade and covering the display, the shutter being coupled to the measurement device. The shutter opens to reveal the display during activation. The enclosure obscures the facade and the shutter from recognition when the measurement device is not in the active state.

  • Patent number: 6180892
    Abstract: An improved mixing scale, such as a paint mixing scale, includes a base which supports a scale pan in a substantially horizontal position. The scale pan supports a receiver container for holding the contents of that which is to be weighed. The mixing scale also includes a backing member which extends upwardly from the base and includes an output display near a top end of the member for presenting the measurement values produced by the scale. Proximate to the output display is a visual flow monitoring device, such as a reflector. Placement of the reflector proximate to the output display allows a user of the mixing scale to monitor the measurement value presentation and the flow of an additive being delivered into the receiver container simultaneously, or at the very least without requiring a physical shift in position by the user which might otherwise disrupt the delivery operation.

  • Patent number: 5167289
    Abstract: An air spring load monitoring system provides a vehicle operator with an on-board visual display of the load distribution imposed on each axle from front to rear of a truck and trailer, and displays differential loads imposed from side to side across each axle as a result of local overloading caused by unequal load distribution. Pneumatic transducers produce analog output signals proportional to the internal air pressure of each air spring as an accurate indicator of payload distribution. Load data is presented by load display groups in which visual display elements are positioned in spaced relation along a scale representative of a predetermined air spring load range. The visual display elements of each group are positioned in side by side relation for visual comparison to each other and to the scale. Each visual display element is representative of a predetermined load range increment.

  • Patent number: 4852674
    Abstract: In the field of off-highway trucks, overloading and disproportionate load placement lead to undesirable vehicle stresses. The present invention pertains to an apparatus for displaying the distribution of the load, in an off-highway truck, to both the truck operator and the loader operator. The information is conveyed to the operators using displays having varying color ranges generally indicative of the load in portions of the dump body of the truck. Using this tool the truck operator attains optimum positioning of the truck prior to and during the loading cycle, while the loader operator directs loads to portions of the dump body having lower displayed loads.

  • Patent number: 4582152
    Abstract: The specification discloses a balance for measuring a load. This balance uses an electronic or optical transducer and a parallelogram support for the load to be weighed. The parallelogram linkage uses one or more torsion bars to resiliently support the load, wherein the deflection of the parallelogram is proportional to the weight of the load. When used with a capacitance transducer, the parallelogram linkage also enables the capacitor plates to remain parallel to one another as the parallelogram is loading, thereby producing a signal that can be electronically processed to provide a liner digital read out signal on indication of weight. Electronic data processing means as provided to calculate and display on indication of weight and/or volume. An optional opitcal indicator means is also disclosed to provide an optical reading of the weight of the load.

  • Patent number: 4554988
    Abstract: When a measuring instrument normally displaying digital values by selective energization of a multi-segment display is used to furnish only qualitative information as to the relationship of the measured value to a reference value or values, the result is indicated only by the position on the display of a horizontal line. Since the change in position is limited by the position of the top and bottom segments constituting the digital display, the read-out of these conventional scales is difficult, particularly when carried out from different angles. To eliminate this problem, a reference mark or marks are supplied. The position of the weight dependent marks relative to the reference mark is clear, eliminating read-out errors. The reference mark may be a permanent mark on a transparent sheet mounted in front of the display. Alternatively, the reference marks can be created by activation of segments in places of the display not required for generating the weight dependent marks.
