In accordance with various aspects of the disclosure, devices and methods are disclosed that include measuring, at a transmitter, a reflected power level corresponding to a specific transmit power level, and setting the transmit power to an operational level. At the transmitter, a new operational level of the transmit power may be determined, for example, by selecting at least one trial transmit power level, and based on reflected power levels measured corresponding to the operational level and the at least one trial level of the transmit power, either maintaining the operational level as the new operational level, or determining the at least one trial level as the new operational level. The operational transmit power level may correspond to a lowest reflected power level, or a highest rate of change of the reflected power level with respect to the transmit power level.

Techniques are provided for enhancing electrical properties of semiconductor structures. At a semiconductor structure, a heterojunction interface is provided between two dissimilar materials such that a two-dimensional electron gas (2DEG) region is present in the vicinity of the heterojunction. Energy is added to the semiconductor structure such that electrons that are present in the 2DEG region are promoted from below the Fermi level to energy states sufficiently high that the electrons can escape the structure. Electrons are emitted from the semiconductor structure in response to adding the energy such that electrons escape the surface of the semiconductor structure.

Various embodiments of the invention may use a radio frequency identification (RFID) tag with a writable non-volatile storage element to receive and store configuration parameters for a device connected to the RFID tag, even if the device itself is powered off. Upon power-up and startup of the device, the device may read the configuration parameters from the RFID tag and install them for its subsequent operation. Some embodiments may work in the opposite direction, by allowing the powered device to write its configuration data into the RFID tag's storage element, whose contents may subsequently be transmitted by the RFID tag to an RFID reader, even if the device is unpowered at the time of transmission.

In various embodiments of the invention, a power-harvesting termination circuit may be used to 1) match the impedance of a signal line being terminated, and 2) recover a portion of electrical power from a signal on the signal line and provide the recovered power as an electrical voltage to be used to power other circuits. The power may be harvested at either the receiving device or at the transmitting device.
摘要:
A micro-electromechanical system (MEMS) switch comprises a trench formed in a substrate. A free moving conductive mass may be formed within the cavity. When the switch is moved or otherwise acted upon my an inertial force to conductive mass makes contact with a pair of electrodes partially covering the trench thus turning the switch on.
