Abstract: A remote control system, set forth by way of example and not limitation, includes a remote control device including one or more controls operative to develop at button control signals in response to activation by a user. An interface device is responsive to the button control signals and is operative to provide device control signals via a wired connection to an electronic display device. The device control signals are operative to control an application running on an electronic display device.

Abstract: In some implementations, a gasket, set forth by way of example and not limitation, includes a housing having a plurality of openings operative to receive a plurality of prongs of a power connector for an appliance. At least one sensor is operative to sense at least one characteristic of an environment. A transmitter is operative to transmit one or more signals derived from the at least one sensed characteristic, where the transmitted signals are capable of being received by a receiving device. A power circuit is operative to provide power from the electric current to the at least one sensor and the transmitter.

Abstract: In an embodiment, set forth by way of example and not limitation, a power line surge protector circuit includes a first input node, a second input node, a first output node and a second output node; a semiconductor shunt having an avalanche breakdown potential, the shunt being coupled between the first input node and the second input node, whereby a voltage potential between the first input node and the second input node which is in excess of the avalanche breakdown potential shunts current between the first input node and the second input node; and a resettable circuit breaker coupled between the first input node and the shunt.

Abstract: Radio-tagged components are used a welding operation to form a welded product. Pedigree/quality control is monitored by tagging welding wire with a first radio transceiver storing information about the wire; providing a second radio transceiver at the welding apparatus, providing a third radio transceiver associated with the at the human operator, logging information about the wire, the operator, and the characteristics of the weld, and maintaining the logged information at a location remote from the welder along with a time stamp and a means of authenticating the maintained log. The first, second and third transceivers operate at a frequency below 1 megahertz, preferably below 300 KHz. A similar radio tag with product pedigree information may also be affixed to the welded product.

Abstract: An RFID tag in a receptacle is active and includes a microprocessor, a data storage device operable to store a selected code (e.g. an ID code to identify said object or said product), the object including a display for displaying the aforesaid selected code upon a signal from the microprocessor and an energy storage device (e.g. a lithium ion battery), operable to energize the microprocessor, the display, and the transmitter. The tag has an antenna having a dimension thereof that is substantially as large as to a maximum dimension of receptacle.

Abstract: A retention clip for retaining a compact flash drive on a PC board includes a flash drive contact portion. The flash drive contact portion includes first and second leg portions extending in an outward direction from the flash drive contact portion. The first leg portion includes a first foot portion extending at an angle from the first leg portion to allow the first foot portion to be inserted into a first opening formed in the PC board. The second leg portion includes a second foot portion extending outward from and parallel to the second leg portion to allow the second foot portion to be inserted in a second opening formed in the PC board. The flash drive contact portion secures the compact flash drive in a fixed position.
