20110138883	INJECTOR FLOW MEASUREMENT FOR FUEL CELL APPLICATIONS - A method for determining the amount of fuel flow from a high pressure gas tank to the anode side of a fuel cell stack through pulsed injector. The anode sub-system pressure is measured just before the injector pulse and just after injector pulse and a difference between the pressures is determined. The difference between the pressures, the volume of the anode sub-system, the ideal gas constant, the anode sub-system temperature, the fuel consumed from the reaction in the fuel cell stack during the injection event and the fuel cross-over through membranes in the fuel cells of the fuel cell stack are used to determine the amount of hydrogen gas injected by the injector.	06-16-2011

20110143234	INJECTOR CONTROL FOR FUEL CELL SYSTEM - A fuel cell system that employs an injector/ejector for providing fresh hydrogen and anode recirculation gas to the anode side of a fuel cell stack. The injector/ejector is operated with a variable frequency so that the injector open time at low stack current densities is long enough to allow a pressure drop to be provided in the anode flow channels to push out water that may have accumulated therein. In one embodiment, the injector/ejector control provides a minimum pulse width per cycle and a maximum frequency so that as the stack current density decreases below a certain value the frequency decreases from the maximum frequency to maintain the pulse width constant at the minimum pulse width.	06-16-2011

20090033632	INTEGRATED TOUCH PAD AND PEN-BASED TABLET INPUT SYSTEM - Integrated touch pad and pen-based tablet input devices and systems are described herein. At least some illustrative embodiments include an input device that includes a touch pad that detects when a surface of the touch pad is contacted by a finger of a user (the surface of the touch pad defining a first x-y plane), and a pen-based tablet comprising a sensing array, wherein the sensing array detects when a stylus associated with the sensing array is proximate to the sensing array (the sensing array defining a second x-y plane that is beneath the first x-y plane). The touch pad is mounted above and proximate to the sensing array, such that the sensing array detects when the stylus is proximate to the surface of the touch pad.	02-05-2009
20110069640	Wireless Access Point - An electronic assembly includes a power supply, a wireless access point, and wired network connectivity. Power for the wireless access point may come from the power supply, or alternatively, from power through the wired network. The power supply can also provide removable power to a portable information device. The wireless access point may optionally be configured to communicate wirelessly only with one particular wireless client.	03-24-2011
20110109557	Automatic Enablement And Disablement Of A Cursor Mover - A computer system includes a keyboard having at least one cursor mover, and at least one sensor. The sensor can detect whether a hand is near the sensor. When the sensor fails to detect a hand near the sensor, at least one cursor mover is enabled.	05-12-2011
20110151973	Portable Computer With Multiple Graphics Displays - A portable computer comprises a base and a display lid hingeably coupled to the base. The display lid comprises a front surface and first and second graphics displays mounted in the display lid and viewable from the front surface. The second graphics display is smaller than the first display. Other portable computers include the second graphics display in the base rather than in the display lid.	06-23-2011
