20100022285 | APPARATUS AND METHOD FOR RETROFITTING A BROAD RANGE OF MOBILE DEVICES TO RECEIVE WIRELESS POWER - Apparatus and method for retrofitting a mobile electronic device, which has an input power receptacle located on its side, to receive power from a power delivery pad that has a flat power delivery surface. A connector assembly is connectable to the mobile electronic device by plugging a connector into the input power receptacle of the device. A power receiver assembly connects pivotally and electrically to the connector assembly by magnetism. The power receiver assembly is pivotal to position a power receiver hub, which is at a fixed distance from the connector assembly, over an axis of the mobile device, where an anchor comprising magnetic material or a mechanical attachment apparatus is adhered to the surface of the mobile device, and the hub is attached to the anchor by magnetism also, so that it is simply and easily detachable and re-attachable. The connector is adjustable in the connector assembly to position the power receiver assembly flush with the surface of the mobile device. Alternate connector assemblies with differently configured connectors are attachable magnetically or mechanically to the power receiver assembly. | 01-28-2010 |
20100055928 | CONNECTOR FOR PROVIDING POWER TO A MOBILE ELECTRONIC DEVICE - It is sometimes advantageous to provide power to the mobile electronic device while using the mobile electronic device. The present connector transfers power from a power source to the mobile electronic device via an element module, a cable, and a plug of the connector. The connector enables the user to: a) interface the element module with the mobile electronic device; and, b) interface the plug with a power source (wall transformer, automobile power jack, aircraft power jack, etc.). | 03-04-2010 |
20100102789 | SWITCH-MODE POWER SUPPLY METHOD AND APPARATUS USING SWITCH-NODE FEEDBACK - Example switch mode power supplies, including buck converters, with indirect, switch-mode feedback for pulse width modulation and duty cycle control are described and shown. Non-idealities are corrected with several example compensation methods and apparatus, including current sense and corresponding voltage adjustment. | 04-29-2010 |
20100156197 | APPARATUS AND METHOD FOR RECEIVING POWER WIRE-FREE WITH IN-LINE CONTACTS FROM A POWER PAD - A linear contact array comprising three contacts is provided for wire-free electric power extraction from a power delivery pad for mobile electronic devices. The linear contact array is configured to assure effective contact for power transfer from the power delivery pad and the mobile electronic device anywhere on the power delivery surface for a range of angular orientations of the linear array in relation to the power delivery surface. | 06-24-2010 |
20110148041 | SYSTEMS AND METHODS FOR PROVIDING ELECTRIC POWER TO MOBILE AND ARBITRARILY POSITIONED DEVICES - Various contact systems and methods for manufacturing and using such are disclosed herein. Examples of the contact systems include a surface with one set of pads biased at a first voltage level, and another set of pads biased at a second voltage level. Such a contact system can be used, for example, to transfer power to an electromechanical device disposed thereon. In one particular example, the electromechanical device can include a power storage element and two or more couplings. When one of the couplings contacts a pad biased at the first voltage level, and another of the couplings contacts a pad biased at the second voltage level, a circuit is completed where some derivative of the differential between the first voltage level and the second voltage level is placed across the power storage element. Completion of the circuit causes the power storage element to charge. Power can be drawn from the power storage element to operate the electromechanical device. | 06-23-2011 |
20110165821 | METHOD AND APPARATUS FOR PRODUCING AMBULATORY MOTION - Apparatus for ambulatory motion includes an exit slot of non-zero width and a bar or leg of non-zero and non-uniform width extending through the slot and connected to a crank constrains the bar or leg in a manner that produces nearly rectilinear motion of a distal end of the bar or leg when a proximal end of the bar or leg is connected to a crank and the crank is rotated. | 07-07-2011 |
20110210617 | POWER TRANSMISSION ACROSS A SUBSTANTIALLY PLANAR INTERFACE BY MAGNETIC INDUCTION AND GEOMETRICALLY-COMPLIMENTARY MAGNETIC FIELD STRUCTURES - Geometrically complimentary magnetic field structures are adapted for efficient power transfer by induction from a planar power delivery surface to a power receiving device. Planar surface electro-magnetic coil pole areas for power delivery and receiver coil assemblies as well as several would coil apparatus and configurations are included. | 09-01-2011 |
20110309771 | PROPORTIONAL REMOTE CONTROL - Disclosed is a proportional controller that utilizes a deflected metal cantilever that provides a progressive change in capacitance for a given deflection that is used to generate a proportional control signal. In addition, a efficient step-up converter | 12-22-2011 |
20120080958 | RELIABLE CONTACT AND SAFE SYSTEM AND METHOD FOR PROVIDING POWER TO AN ELECTRONIC DEVICE - An electronic system which includes a power delivery surface that delivers electrical power to an electrical or electronic device. The power delivery surface may be powered by any electrical power source, including, but not limited to: wall electrical outlet, solar power system, battery, vehicle cigarette lighter system, direct connection to electrical generator device, and any other electrical power source. The power delivery surface delivers power to the electronic device wirelessly. The power delivery surface may deliver power via a plurality of contacts on the electrical device conducting electricity from the power delivery surface. The electrical device may be mobile device. Each contact may be shaped to improve power delivery reliability. The power delivery surface may further include circuitry to protect against accidental electrocutions. | 04-05-2012 |
