Abstract: A method, computer program product, and system are disclosed for facilitating access by a first person to a secure region that is at least partly defined by an access control device. The method acquires, using at least one visual sensor, first image information including the first person and the access control device. The method identifies the first person using image analysis performed on the first image information. The method further identifies a first behavior of the first person relative to the access control device. Upon determining the first behavior corresponds to a predefined visual access behavior indicating that the first person is in the process of manually operating the access control device, and that the security level of the first person satisfies a predetermined threshold security level associated with the access control device, the method permits the first person to physically access the secure region.

Abstract: A method, computer program product, and system are disclosed for facilitating access by a first person to a secure region within an environment having a plurality of items, wherein the secure region is at least partly defined by an access control device. The method acquires, using at least one visual sensor disposed within the environment, first image information including the first person and the access control device. The method identifies the first person using image analysis performed on the first image information. Further, the method identifies, using image analysis a first behavior of the first person relative to the access control device. Upon determining the first behavior corresponds to a predefined visual access behavior, and the security level of the first person satisfies a predetermined threshold security level associated with the access control device, deactivating a security element to permit the first person to physically access the secure region.

Abstract: A method, a data processing system, and a computer program product identify blockages in a heat sink of a data processing system. An electromagnetic emitter and an electromagnetic detector are positioned on opposite sides of the heat sink. An intensity of a stream of electromagnetic radiation directed from the electromagnetic emitter is measured by the electromagnetic detector. Based on the measured intensity of the stream of electromagnetic radiation as measured by the electromagnetic detector, a blockage level of the heat sink is determined. If the blockage level of the heat sink exceeds a blockage threshold, an alert is generated.

Abstract: A circuit is attached in parallel to a universal serial bus interface of a data processing system. A capacitor in the circuit is charged by receiving power from a power pin of the universal serial bus interface while the data processing system is not in a reduced power state. A vibration sensor is unpowered while the data processing system is not in a reduced power state. The vibration sensor is disconnected from a data pin of the universal serial bus interface while the data processing system is not in a reduced power state. When the data processing system enters a reduced power state, the capacitor provides power to the vibration sensor. When a vibration is detected by the vibration sensor, a switch connects the vibration sensor to the data pin of the universal serial bus interface, providing a wake up signal to the data processing system.

Abstract: A computer implemented method and computer program product for detecting and communicating boot failures in a client device. A Dynamic Host Control Protocol server is configured to monitor Dynamic Host Control Protocol communications from one or more client devices, wherein the client devices are configured to boot from local media. A boot request is received from a client device in response to a failure of the client device to boot from the local media. Responsive to receiving the boot request, a determination is made that a boot failure has occurred on the client device.

Abstract: Systems and methods are disclosed for tracking items in a shopping cart using radio frequency identification. In one embodiment, a first set of items is positioned in a first item zone alongside an aisle. An electronic tag reader is capable of remotely reading identification tags on the items into an electronic record of shopping cart contents when the identification tags are within a readable range from the electronic tag reader. An energy field generator such as an electromagnetic field generator generates a first electromagnetic field extending from a location within the readable range of at least some of the items in the first item zone to a location outside the readable range of any of the items in the first item zone.

Abstract: A computer implemented method for managing power usage in a data processing system. Power usage by a set of input/output devices attached to the data processing system is monitored. If it is determined that the power usage requires a change in power consumption by a processing unit, the clock speed of the processing unit is changed to change the power consumption by the processing unit.
