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.

A load sensor compares generated values of load signals to predicted values of the load signals. Where an error between a generated value and a predicted value is less than a threshold, a value of zero is transmitted by the load sensor to an external systems, in an encoded stream of bits, and the error are used to calculate a predicated value of a next load signal, such that insubstantial changes in loading resulting in small errors are not transmitted to the external system. Where an error between the generated value and the predicted value exceeds the threshold, however, a value representative of the error is transmitted to the external system, in an encoded stream of bits. The external system processes the stream of bits to calculate the error, to determine that an item has been placed on a storage system or removed therefrom, or to identify the item.

Compressing load signal transmissions

Modular storage systems include load sensors disposed beneath or in association with platforms. The load sensors are pulse-sampled for signals corresponding to loads at time intervals, rather than continuously, in order to conserve electrical power. An item associated with a transaction is identified based on a change in the loads, as determined from the pulse-sampled signals. The platforms are aligned at horizontal or non-horizontal angles, and photovoltaic power sources with banks of photovoltaic cells are mounted to front edges of the platforms. When a user reaches over one of the photovoltaic cells to access an item on a platform, a level of power or voltage generated by the photovoltaic cell is diminished. The item closest to the photovoltaic cell having the diminished power or voltage, or a customer that accessed the item, may be identified accordingly.

Modular storage systems

An apparatus includes a platform or other accessory that is supported by one or more transducer assemblies using piezoelectric transducers. In one implementation, a saddle structure provides mechanical support to a platform while transferring force from a load onto a portion to which a pair of piezoelectric transducers are affixed. As a load on the saddle changes, the resulting change in strain on the portion produces signals from the piezoelectric transducers. In another implementation a beam provides mechanical support to a platform or other accessory. A pair of piezoelectric transducers are affixed near a strain concentrator, such as a hole in the beam, produce signals indicative of a change in load on the beam.

Piezoelectric weight sensing apparatus

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.

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.

Position sensing weight measuring device

An apparatus includes a platform or other accessory that is supported by one or more piezoelectric transducers. As items are placed on or removed from the accessory, the piezoelectric transducer generates an electric charge that is representative of a change in weight. An amplifier receives the charge and provides output voltage that can be sampled to determine a weight value. In one implementation the platform may be supported by a transducer assembly comprising a frame and a pair of piezoelectric transducers on opposite sides of the frame. Signals from the pair may be used to compensate for environmental effects on the assembly, such as changes in temperature. The piezoelectric transducers and associated circuitry are extremely energy efficient, consuming little electrical power during operation.

This disclosure describes, in part, systems for tracking the removal of shopping bags or other items from a dispenser. Folded shopping bags are stacked in a holder so that a front shopping bag can be removed by pulling it along an axis that is parallel to the length and/or width dimension of the shopping bag. A motion sensor is positioned to sense movement of the front shopping bag as it is removed. Control logic monitors and/or analyzes data or other signals from the motion sensor and determines whether movement of at least a threshold distance has occurred. If movement of at least the threshold distance has occurred, the control logic concludes that a shopping bag has been removed and generates a corresponding event notice. Other system components may respond to the event notice by applying a charge for the removed shopping bag or by performing other actions.

Cable housing assemblies include frames and cable carriers slidably mounted to channels provided at edges of the frames. The cable carriers may house or support male or female connectors to the cables, which may be power or communications cables (e.g., Ethernet cables) that extend from the connectors within the cable carriers into the channels, and through voids within the frames to power sources or communications systems. The cable carriers are releasably inserted into channels at edges of the frames, and permitted to slide in either direction (e.g., up or down) to various positions within such channels, in order to make power or communications services available at such positions. When installed in association with a shelving unit, e.g., between a backerboard and shelves, the cable carriers may be used to provide power or communications services available to such shelves provided at any height within the shelving unit.
