Abstract: A platform is supported at four corners by four half-bridge load cells. Adjacent load cells are oppositely polarized. During operation, analog output from a pair of oppositely polarized half-bridge load cells is provided to an instrument amplifier. Analog output from the instrument amplifier is provided to an analog to digital converter to provide digital data. The digital data is then used to determine weight data indicative of a weight as measured by the pair of half-bridge load cells at that time. A set of switching elements, such as a quad bilateral switch controlled by a microcontroller, rapidly switch between pairs of oppositely polarized load cells. The weight data may be used to determine an overall weight change on the platform, such as a pick or a place of an item. Weight data from the four pairs of load cells may be used to determine a change in center of gravity.

Abstract: An apparatus comprising an array of electrical conductors connected to circuitry that determines data indicative of objects at particular locations based on capacitance at junctions of conductors in the array. The apparatus comprises a first set of conductors arranged on a first substrate and a second set of conductors arranged on a second substrate to form an array. The first and second substrates are separated by an air gap within which the electrical conductors are positioned. Each conductor may be independently addressable, having a proximal end connected to readout electronics and a distal end that is not. The apparatus may be cut, at the ends distal to where the conductors connect to the circuitry, to fit a desired location, such as on a store shelf, while remaining operational.

Abstract: An impulse strip including a plurality of clips, hooks or other features for attaching items to the impulse strip also includes a plurality of switches associated with each of the clips, hooks or other features. The switches are in communication with illuminators or other indicators that are arranged in an array. When an item is loaded onto the strip, or removed from the strip, a switch may be opened or closed, causing one of the illuminators in the array to be activated or deactivated accordingly. An image captured of the illuminators is processed to determine which of the illuminators is activated and which is deactivated, and an inventory level of the strip may be determined based on the statuses of the respective illuminators corresponding to the clips, the hooks or the other features of the impulse strip.
