Plural Distinct Load Holders With Common Evaluator Patents (Class 177/199)
  • Patent number: 10976824
    Abstract: A reluctance haptic engine for an electronic device includes a core, an attractor, and one or more flexible support members. The core and/or the attractor may be coupled to an input structure, such as a button cap, trackpad cover, touchscreen cover, or the like. In an unactuated configuration, flexible support members maintain a gap between the core and the attractor. An electrical current may be applied to one or more conduction loops of the core to actuate the reluctance haptic engine and provide a haptic output by moving the input structure. The electrical current may cause a magnetic flux that results in a reluctance force that pulls the attractor and the core together and causes the input structure to move (e.g., translate, rotate, oscillate, vibrate, or deform) to produce a haptic output.

    Abstract: Shelves or other fixtures may be used to hold items at a facility. Load cells at the shelf may be used to acquire weight data indicative of changes as items are added or removed from the shelf. The shelves may be part of a fixture that includes a door that results in air movement with respect to the shelves when opened or closed. This air movement may produce weight data that is erroneously indicative of an event, such as a pick or place, even when no actual event has taken place. Weight data from load cells of a shelf may be analyzed to determine a trajectory associated with changes in the weight data over time. A portion of the space may be designated as being associated with invalid weight data. If the trajectory avoids this portion of the space, the weight data may be deemed valid.

    Abstract: Weighing scale apparatuses (devices and systems) and methods are implemented using a variety of biometric-based devices and methods. According to one such implementation, a weighing scale uses a base unit to integrate a support structure, a display, and circuitry to measure and determine the physiological parameters of the user, including a user-weight metric. The support structure includes a platform region that utilizes sensor circuitry to collect physiological data from the user, which is then processed by user-targeted circuitry to determine the physiological parameters (e.g., weight and heart-related measurements) of the user. Such parameters are then associated with the user and saved to a data-access circuit, and also forwarded to a display which communicates the physiological parameters among other information to the user through the platform region; the display encompassing substantially all of the platform region, including the region(s) upon which the user would stand for weight measurements.

  • Patent number: 7406927
    Abstract: A system for weighing a plurality of quadruped animals is for use in a pen confining the animals. The pen has at least first and second segregated spaces with a first one-way chute allowing animal passage from the second space to the first space. A weighing station is located within a passage having an entrance and an exit, and that allows animal passage from the first area to the second area. The weighing station includes a weighing platform within the passage over which an animal must pass when passing from the first to the second space. The weighing platform has inlet and exit scales that support the weighing platform adjacent to inlet and exit ends thereof, and provides inlet and exit weight signals. A controller receives the inlet and exit weight signals and uses them in an iterative process to determine the presence of a single animal on the weighing platform. Once that determination is made, the sum of the inlet and exit weight values is very likely to accurately provide the animal weight.

  • Patent number: 7361851
    Abstract: A weighing apparatus comprises a plurality of load cells and a load platform, supported by the load cells. The apparatus includes means associated with each load cell to supply a digital representation of the load on each load cell. The load cells are connected together to form a communication network. In the network, a digital representation of the load on each load cell is generated, and a correction coefficient of the digital representation for each cell is determined. The correction coefficient is stored in each respective load cell, and again of each load cell is varied according to its correction coefficient to generate a correct digital representation of the load for each load cell.

  • Patent number: 7253366
    Abstract: A system for monitoring a patient on a hospital bed includes load cells and a controller for detecting patient movement on, exit from, and impending exit from the hospital bed, including movement across or outside a virtual boundary or region located on the bed. The controller is configured to detect changes in the distribution of patient weight among the load cells. The controller is also configured to accommodate the installation or removal of medical equipment or other tare weights on the bed, head incline adjustment, and bed frame deformation or other changes in the system causing redistribution of weight among the load cells, while minimizing false alarms. A caregiver may select between various patient monitoring modes and remotely monitor patient movement relative to a reference load cell distribution, impending patient exit from the bed and patient exit from the bed.

  • Patent number: 7244896
    Abstract: In a multipoint scale for weighing a load applied to a placement section by a plurality of weight sensor units, the weight sensor unit includes a weight sensor having a strain-sensitive part; a first flexible elastic member for receiving the load applied to the placement section; a load transmission part for transmitting the load from the first flexible elastic member to a power point of the weight sensor; a load support part for supporting a fulcrum of the weight sensor; and a second flexible elastic member for receiving the load applied to the load support part and for maintaining a direction of the load applied to the strain-sensitive part of the weight sensor to be vertical in accordance with a deflection of the first flexible elastic member. Torsion of the weight sensor is avoided by reducing the effect of deflection of the placement section on transmission of the load to the weight sensor.
