| 20080206113 | Hydrogen Generating Fuel Cell Cartridges - A gas-generating apparatus ( | 08-28-2008 |
| 20080233457 | Fuel Supply with Improved Connecting Valve - Disclosed herein are connecting valves with an interchangeability feature ( | 09-25-2008 |
| 20090130507 | Hydrogen Generating Fuel Cell Cartridges - A gas-generating apparatus includes a reaction chamber having a first reactant, a reservoir having an optional second reactant, and a self-regulated flow control device. The self-regulated flow control device stops the flow of reactant from the reservoir to the reaction chamber when the pressure of the reaction chamber reaches a predetermined level. Methods of operating the gas-generated apparatus and the self-regulated flow control device, including the cycling of a shut-off valve of the gas-generated apparatus and the cycling of the self-regulated flow control device are also described. | 05-21-2009 |
| 20090205727 | Fuel Cartridge with Connecting Valve - A shut-off valve or connecting valve capable of connecting a fuel supply to a fuel cell is disclosed. The valve comprises a first valve component and a second valve component. Each valve component has an outer housing and a biased slidable member disposed inside the housing forming an internal seal. During the connection process, the two valve components establish an inter-component seal. Afterward, in one suitable embodiment the slidable member moves inward and opens the internal seal in the valve component to establish a flow path. In another embodiment, the slidable member moves inward and exposes a first filler and the first filler abuts a second filler in the other valve component to establish a flow path. In other embodiments, at least one valve component is sized and dimensioned to limit access to the internal seal. | 08-20-2009 |
| 20100099009 | VALVES FOR FUEL CARTRIDGES - Valves for connecting fuel supplies are disclosed. The fuel supplies can be a pressurized or non-pressurized cartridge that can be used with any fuel cells. The valves may include valves that vent gas from the cartridge and allow byproducts produced by the fuel cell to be transported to the fuel cartridge, and valves that connect the fuel supplies to the fuel cells | 04-22-2010 |
| 20100112400 | Fuel Cell Supply Including Information Storage Device and Control System - The present invention is directed to a fuel cell system with various features for optimal operations of an electronic device, a battery charger or a fuel refilling device. The fuel cell system includes an information storage device associated with the fuel supply, pump and/or refilling device. The information storage device can be any electronic storage device including, but not limited to, an EEPROM or a PLA. The information storage device can include encrypted information. The information storage device can include software code for confirming the identification of the cartridge before operation of the electronic device and/or refilling device. The information storage device can include instructions for a hot swap operation to shut down properly when the fuel supply is ejected while the electronic device is in operation. The present invention is also directed to system architecture for a fuel cell system that utilizes information storage devices. The system architecture may have flow regulators, which include a regulating valve. | 05-06-2010 |
| 20100151361 | Fuel Cartridges for Fuel Cells and Methods for Making Same - Fuel supplies for fuel cells are disclosed. The fuel supplies can be a pressurized or non-pressurized cartridge that can be used with any fuel cells, including but not limited to, direct methanol fuel cell or reformer fuel cell. In one aspect, a fuel supply may contain a reaction chamber to convert fuel to hydrogen. The fuel supplies may also contain a pump. The fuel supply may have a valve connecting the fuel to the fuel cell, and a vent to vent gas from the fuel supply. Methods for forming various fuel supplies are also disclosed. | 06-17-2010 |
| 20100223840 | Hydrogen Generating Fuel Cell Cartridges - A gas-generating apparatus includes a cartridge including a reservoir having a first reactant and a reaction chamber, and a receiver that can include a flow control device. The receiver is adapted to receive the cartridge and to transport the first reactant to the reaction chamber after connection with the cartridge. The flow control device is adapted to stop the transport of reactant when the pressure in the reaction chamber reaches a predetermined pressure. | 09-09-2010 |
| 20110123889 | Fuel Cell Supply Including Information Storage Device and Control System - The present invention is directed to a fuel cell system with various features for optimal operations of an electronic device, a battery charger or a fuel refilling device. The fuel cell system includes an information storage device associated with the fuel supply, pump and/or refitting device. The information storage device can be any electronic storage device including, but not limited to, an EEPROM or a PLA. The information storage device can include encrypted information. The information storage device can include software code for confirming the identification of the cartridge before operation of the electronic device and/or refilling device. The information storage device can include instructions for a hot swap operation to shut down property when the fuel supply is ejected while the electronic device is in operation. The present invention is also directed to system architecture for a fuel cell system that utilizes information storage devices. The system architecture may have flow regulators, which include a regulating valve. | 05-26-2011 |
| 20110164919 | CONNECTING ASSEMBLY FOR TOOLS AND HANDLES - A connecting assembly is provided that includes a tool receiving portion, a handle receiving portion, a tightening member, a first open region, and a second open region. The handle receiving portion has a first engaging portion, a clamping portion with a first cam, and a longitudinal axis. The tightening member has a second cam and a second engaging portion. The second engaging portion is engagable with the first engaging portion so that the tightening member moves to cause the first and second cams to interact with one another biasing the clamping portion in a desired direction. The first open region is defined at the first engaging portion, while the second open region is defined at the clamping portion so that the open regions are in fluid communication with one another. | 07-07-2011 |
