Some embodiments provide a system for charging devices. The system includes a master device and a slave device. Some embodiments provide a method for charging devices in a system that includes a slave device and a master device. The slave device includes (1) an antenna to receive a radio frequency (RF) beam and (2) a power generation module connected to the antenna that converts RF energy received by the slave antenna to power. The master device includes (1) a directional antenna to direct RF power to the antenna of the slave device and (2) a module that provides power to the directional antenna of the master device.

Methods and systems are provided for achieving delivery of power wirelessly using a highly beam-formed array of radio frequency (RF) transmitters as a source and a spatially beam-formed array of receivers that collect the impinged RF power and feed a multistage RF to direct current (RF-DC) conversion circuit that, for example, increases output voltage by doubling the voltage at each stage, while power delivery remains constant. One or more embodiments may provide energy wirelessly and—unlike conventional systems where the power flux density may be too low for applications where an energy density (specific energy) on the order of several mega-Joules per kilogram (MJ/Kg) is desired—may provide sufficient power flux density for many practical applications.

A look-up table assists a source of logic of an apparatus in determining the power requirements of an unknown battery-powered device, so that a configurable power supply adjusts its output to provide the correct power to the device. The functions of the look-up table, in conjunction with generic templates and update-able historical information, if available, are substantially based on determining a “power signature” of the device. As a secondary function, the look-up table enables detection of battery charging activity and, when necessary, provides various means of disabling charging operations. More than one look-up table is available, and a look-up table can be located at any inter-connected device, apparatus, or power source. Inter-device communications further enhance the functionality of the look-up table, especially for collaborative data-acquisition.

A handheld computing device is disclosed. The handheld computing device includes an enclosure having structural walls formed from a ceramic material that is radio-transparent.

Provided is a electric power transmitting apparatus (300) that has sub-electric power transmission mode, and main electric power transmission mode for transmitting power larger than that transmitted in the sub-electric power transmission mode. A power transmitting unit (310) transmits power in a wireless manner. A electric power transmission control unit (320) controls, in sub-electric power transmission mode, power to be transmitted by means of the power transmitting unit (310) and transmission timing of the electric power transmission such that at least power that the electric power receiving apparatus needs to transmit power request notification is transmitted at random intervals. A electric power transmission control unit (320) performs switching to the main electric power transmission mode, in the cases where a communication unit (350) acquired the power request notification transmitted from the electric power receiving apparatus.

A ground fault detector and interrupter for a photovoltaic (PV) energy conversion system, method and apparatus are disclosed. In an exemplary embodiment, the system includes first and second inputs adapted to couple to a first and second rails of a PV array. An inverter is configured to convert DC power generated from the PV array to AC power. A ground fault detector and interrupter, which is coupled to the first and second rails and to the inverter, is configured to detect ground fault conditions in the PV array and to decouple the PV array from the remaining portion of the PV energy conversion system upon such detection. A known signal is coupled to the input of the ground fault detector and interrupter, and then sensed at the output of the ground fault detector and interrupter to determine whether components of the ground fault detector and interrupter are operating properly.

A clamp includes a housing, a fixed gripper, a moveable gripper, a driven member, and an actuator. The housing includes first and second tracks. The fixed gripper is coupled to the housing. The driven member is configured to slide within the first and second tracks of the housing. The moveable gripper is operatively coupled to the driven member. The actuator is configured to move the driven member towards a first position to thereby move the moveable gripper towards the fixed gripper. The actuator is further configured to move the driven member towards a second position to thereby move the moveable gripper away from the fixed gripper.

The invention relates to an intensive assembling cabinet for large semiconductor equipment. The intensive assembling cabinet comprises a cabinet frame, an outer shell which is wrapped on the periphery of the cabinet frame, and an internal frame arranged in the cabinet frame. The internal frame divides the cabinet frame into a first radiating channel placed on the upper side, a power supply part and a control cabinet, wherein the power supply part and the control cabinet are placed on the lower side and are distributed left and right. The power supply part is connected with the control cabinet through a cable, the power supply part is placed in a stacking mode, and a maintenance space is reserved between the power supply part and the control cabinet. The control cabinet is in a self-rotating mode. According to the intensive assembling cabinet for the large semiconductor equipment, the front face and the back face of the power supply part are maintained through organization layout and the reserved maintenance space, and the rotating function of the control cabinet in the self-rotating mode is used for maintaining the front face and the back face of the control cabinet. The first radiating channel is used for pumping and draining the heat of the power supply part and the control cabinet. Meanwhile, space units for radiating, maintaining and cable placing are merged, and therefore intensive assembling is achieved.

An SFP module includes a housing (1) and an ejector (70). An ejector seat (111) is formed in the housing for receiving the ejector. A triangular latch (114) is formed on the housing behind the ejector seat. The ejector includes a push bar (79) exposed forward of a front end (17) of the housing, and a tongue board (74). Two ejecting protrusions (741) are formed at a rear end of the tongue board, corresponding to a spring tab (611) of an SFP cage (6). The spring tab defines a retaining hole (613) for retaining the latch of the housing. When the SFP module is withdrawn from the cage, the push bar is pressed until the protrusions of the ejector have released the spring tab from the latch of the housing. The SFP module is then ejected from the cage by conventional spring means located in a rear of the cage.
