A low attenuation surface wave transmission line system for launching surface waves on a bare and unconditioned conductor, such as are found in abundance in the power transmission lines of the existing power grids. The conductors within the power grid typically lack dielectric and special conditioning. Accordingly, the present invention includes a first launcher, preferably including a mode converter and an adapter, for receiving an incident wave of electromagnetic energy and propagating a surface wave longitudinally on the power lines. The system includes at least one other launcher, and more likely a number of other launchers, spaced apart from one another along the constellation of transmission lines. The system and associated electric fields along any given conductor are radially and longitudinally symmetrical.

A system and method for supplying power to a load and for controlling the power factor presented to the power line. Output voltage is controlled by a digital, outer, control loop, and inner, analog, control loop causes the input current to be substantially proportional to the input voltage at any particular point in the power line cycle. Thus, the system presents a load to the power line that appears to be purely resistive. The use of an analog multiplier is not required, nor is sampling of input voltage. Limiting of inrush current provides for brown-out protection and soft-start.

A central processing unit (CPU) having a built-in dynamic random-access memory (DRAM) with exclusive access to the DRAM when the CPU performs an interlock access to the DRAM. A memory controller prevents the DRAM from being externally accessed while the CPU is performing the interlock access. When the memory controller receives an external request for accessing the DRAM during a time when the CPU is performing an interlock access to the DRAM, the memory controller outputs a response signal indicating that external access to the DRAM is excluded or inhibited. The request signal can be a hold request signal for requesting a bus right or can be a chip select signal. The response signal can be a hold acknowledge signal or a data complete signal. The memory controller can be switched to and from first and second lock modes, where hold request and hold acknowledge signals are used during the first lock mode and chip select and data complete signals are used in the second lock mode.

An identification system, e.g. for tagging goods in a retail store, has at least one interrogator and a number of transponders for attaching to goods. Each transponder responds to an interrogation signal from the interrogator by returning a response signal containing information stored in the transponder. The transponder can be switched, by means of a mode switching signal from the interrogator, into a reduced power mode in which the power level of the response signal is reduced from its normal level. The reduced power mode may for example be selected when the goods have been paid for, to ensure that the transponder does not trigger an anti-theft gate, which can detect only the normal power level. The transponder can, however, still be read by an interrogator capable of detecting the reduced power level, e.g. at a customer services desk.

Systems, methods, and apparatuses are disclosed for determining dead-times in switched-mode DC-DC converters with synchronous rectifiers or other complementary switching devices. In one embodiment, for example, a controller for a DC-DC converter determines dead-times for switching devices of a synchronous rectifier or other complementary switching device of the converter in which a dead-time is derived from an output voltage or current that is already sensed and used in the output regulation of the converter. In another embodiment, a controller is provided for controlling a switched-mode DC-DC converter comprising a pair of power switches. The controller comprises an input, a reference generator, a comparator, a compensator, a dead-time sub-controller, and a modulator. In another embodiment, the controller may adjust the dead-times during the operation of the converter to adjust periodically and/or in response to changes in operating conditions. In addition, methods of determining dead-times of control signals for a switched-mode DC-DC converter comprising a pair of power switches and of controlling a DC-DC converter are also disclosed.

A wireless LAN device for lessening failure in switching from infrastructure mode to ad-hoc mode. A radio wave coverage storage stores coverage information about coverage of radio waves amongst access points. A terminal information storage stores terminal information about terminals associated with the access points. A packet receiver receives, via the access points, a packet transmitted from any of the terminals in infrastructure mode. An access point acquisition unit looks up the terminal information storage, based on terminal information about originating and destination terminals contained in the packet, to identify access points with which the terminals are associated. A radio wave coverage decision unit looks up the radio wave coverage storage to determine whether the identified access points are within each other's coverage of radio waves. A communication mode switch switches the communication mode of the originating and destination terminals to ad-hoc mode in accordance with the determination result.
