摘要： Apparatus is provided to limit the current drawn from a power supply output connected to furnish power to a docking station or electronic device, when a fault connects the output to ground or other docking connection. The power supply is disconnected when such fault is present during power-up. In one embodiment, the apparatus controllably limits current delivered to a docking station and a mobile device connected thereto. The apparatus includes a switch device located along a current path extending between the power supply and docking station, to regulate current flow. A current limiting entity operates the switch device to prevent current flow, when the fault affects the circuit, and current through the path exceeds a pre-specified threshold level. The pre-specified current threshold level can be less than the current level provided to the docking station and mobile device without said fault. A disabling component de-activates the current limiting entity, when current is flowing to the charging station but the current is unaffected by the fault.

摘要： 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, the purchase transaction is processed and, if the item is successfully purchased (i.e., transaction confirmed), 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 indicating that an un-purchased product is being placed in the customer's sack.

摘要： A method for reducing the impedance of a reference path in a printed circuit board includes forming a printed circuit board having a plurality of conductive layers including first, second, third, and fourth layers. The printed circuit board includes two or more vias interconnecting two or more of the conductive layers. A first via is part of a signal path configured to carry a signal from the first layer to the second layer. A second via is part of a reference path configured to carry said signal from a third layer to a fourth conductive layer. The method further includes embedding an electrical component, such as a capacitor, in the second via between two of the conductive layers.
