Abstract: A non-volatile multi-bit storage device that includes a phase change material doped with n-type or p-type semiconductor impurities, a first set of electrodes ohmically coupled to the phase change material, a second set of electrodes configured to apply an electric field across the phase change material. To program the non-volatile multi-bit storage device, an electrical field is applied to the phase change material as crystal annealing cool down is performed. Application of the electric field during the crystal annealing cool down forms a rectified current path through the phase change material.

Abstract: Techniques of self-checkout alerts based on packaging detection. A given bag type of a bag selected at a self-checkout kiosk is identified out of a bag types available from a bag dispenser associated with the self-checkout kiosk, the bag being an empty bag. A weight range of the empty bag is identified based on the given bag type. An allowed weight range of a combination of the empty bag and a desired item is determined based on the weight range of the empty bag, a weight of the desired item as measured by a terminal scale, and at least one of a measurement tolerance of the terminal scale and a measurement tolerance of a platform scale. A loss prevention alert is generated, and a transaction at the self-checkout kiosk is paused, upon determining that the allowed weight range is exceeded.

Abstract: Techniques for self-checkout alert reduction based on packaging detection. A deflection in a first bag reservoir associated with a self-checkout kiosk is determined. The first bag reservoir is positioned adjacent to a packing area and includes a first type of bags. The self-checkout kiosk includes a terminal scale and further includes a platform scale in the packing area. That an empty bag is retrieved from the first bag reservoir is determined based on the deflection in the first bag reservoir. A bag type and a weight range are identified for the empty bag. An allowed weight range of a combination of the empty bag and a desired item is then determined. Presence of the empty bag on the platform scale is prevented from causing a loss prevention alert to be generated when the desired item has been placed in the empty bag on the platform scale.

Abstract: The present disclosure provides improved packaging detection at self-checkout kiosks by identifying a given bag type for a bag selected at a self-checkout kiosk out of a plurality of bag types available from a bag dispenser associated with the self-checkout kiosk; identifying a weight range for the given bag type; in response to determining that the bag has been moved to a packing area of the self-checkout kiosk, comparing a first weight in the packing area from before the bag was moved to the packing area with a second weight in the packing area that includes the bag; and in response to a difference between the first weight and the second weight falling outside of the weight range, generating a loss prevention alert and pausing a transaction at the self-checkout kiosk.

Abstract: A method and system for enabling reliable verification of items being purchased using a self checkout system. The self checkout system is equipped with a verification mark dispenser and verification mark detectors that respectively dispenses a mark on an item as the item is being scanned for purchasing and then verifies, by detecting the mark on the item, that the item being bagged (or passed through the tunnel) is the same item that was scanned. When a customer scans an item for purchase, and if purchase transaction is successful, a mark (made of a non-reactive but detectable material or ink) is placed on the exterior packaging of the item. When the item is placed in the tunnel, the detector, sensitive to the activation of the specific marking and located at or in the tunnel, detects the marking on the item. If the activated marking is not detected by the detector, an alert condition is triggered.

Abstract: A method and system for providing a touch interface on a display are described. The method and system include providing an emitter on a first side of the display and providing a detector on a second side of the display. The emitter provides an electromagnetic signal to the display. The electromagnetic signal has a path from the emitter to the detector through the display in the absence of a user's touch such that the electromagnetic signal is detected by the detector in the absence of the user's touch. The path includes at least one total internal reflection in the display. The emitter and the detector are configured such that the user's touch at any of the at least one total internal reflection alters the path such that a portion of the electromagnetic signal does not reach the detector.

Abstract: An improved resistive touch panel is disclosed. The improved resistive touch panel includes a first plurality of stripes of a resistive coating on a front sheet running in a first direction and a second plurality of stripes of a resistive coating on a back sheet running in a second direction. The overlapping regions between the first and second plurality of stripes are scanned by a controller circuit to detect voltage drops at these regions. Because the overlapping regions are independent of each other, the controller circuit is able to detect the individual regions involved in the touch area. In this manner, the controller circuit is able to determine between small and large areas of contact by detecting adjacent contact areas.
