| 20090162077 | Precision timing pulse width communications systems and methods - Systems and methods are described for pulse communications using precision timing. A method includes digitally pulse coding a data stream; and modulating a carrier signal using the digitally pulse coded data stream. | 06-25-2009 |
| 20090201982 | Precision timing pulse width communications methodology - Systems and methods are described for pulse communications using precision timing. A method includes digitally pulse coding a data stream; and modulating a carrier signal using the digitally pulse coded data stream. | 08-13-2009 |
| 20090250020 | Reciprocating combustion engine - Methods and apparatus are described for a reciprocating combustion engine. A method includes operating a dual-piston engine including introducing a gas into a pair of combustion chambers; introducing a fuel into the pair of combustion chambers; compressing the gas; combusting the gas and the fuel; and exhausting combusted gases. Each of the pistons drives a reciprocating crankshaft that protrudes through a cylinder wall and cooperatively rotate a pair of rotors by engaging substantially sinusoidal cam tracks on the rotors. An apparatus includes a cam driven, concentric drive rotary-valve dual-piston engine. | 10-08-2009 |

| 20090102457 | Automated Test Equipment Interface - An automated test equipment interface system, e.g., for attaching a handler to a test head, includes a device interface board assembly. The device interface board assembly includes a stiffener frame having a frame body that is configured for attachment to a test head, alignment brackets connected to the frame body, and cam followers connected to the alignment brackets. The system also includes a docking device. The docking device includes a docking plate that is configured for attachment to a handler, pull-down ramps connected to the docking plate and movable between a retracted position and an extended position, an actuator operable to initiate movement of the pull-down ramps, and a coupling that translates movement of the actuator to corresponding movements of the pull-down ramps. The pull-down ramps can include cam surfaces that are configured to engage the cam followers of the device interface board assembly during movement between the retracted and extended positions to pull the device interface board assembly towards the docking plate. | 04-23-2009 |

| 20080249604 | APPARATUS AND METHOD FOR MEDICAL PROCEDURES WITHIN A SPINE - Devices and methods for performing a procedure within a spine are disclosed herein. In one embodiment, a method includes inserting an expandable member into an interior of a bone-related structure. The expandable member defines a first and second lumen. A medium is delivered through the first lumen and into the interior of the expandable member while within the interior of the bone-related structure. A filler material is delivered through the second lumen and into a cavity within the interior of the bone-related structure while the expandable member is disposed therein. An apparatus can include an expandable member that defines a first lumen in fluid communication with an interior volume of the expandable member, and a second lumen in fluid communication with an opening of the expandable member. The second lumen is configured to communicate a filler material through the opening and into an interior cavity of a bone-related structure. | 10-09-2008 |
