| 20090044023 | CONTROL DEVICE WITH AN INTEGRATED USER INTERFACE - A control device for controlling operation of a controlled apparatus is disclosed. The control device may include a sensor configured to acquire a first biometric signal, a second biometric signal, and a third biometric signal. A difference between the first biometric signal and the second biometric signal may be utilized to determine movement of a controlled object. The controlled object may pertain to the operation of the controlled apparatus. At least one of the first biometric signal, the second biometric signal, and the third biometric signal may be utilized to initiate performance of a first function of the controlled apparatus. Further, one or more of the first biometric signal, the second biometric signal, and the third biometric signal may be utilized to determine an identification of a user. | 02-12-2009 |
| 20100057946 | TYPE A USB RECEPTACLE WITH PLUG DETECTION - A modified Series A universal serial bus (USB) receptacle connector is equipped with the functionality to allow the electronic system in which it resides to be configured either as a host device or a peripheral device. The modified USB Series A receptacle connector, according to one embodiment of the invention may include a mechanism such as an additional pin or a mechanical switch to detect the presence of a standard USB Series A plug being inserted into it. Upon detection of a plug, an algorithm may allow the system to determine whether it is to act as a host device or a peripheral device and to determine which device supplies power. | 03-04-2010 |
| 20100079468 | COMPUTER SYSTEMS AND METHODS WITH PROJECTED DISPLAY - Computer systems and methods may provide a projection display as a primary visual output. In particular, a computer system may include an integrated projector output. Such a computer system may be substantially or even entirely externally wire-free. Methods of image processing may involve a computer system with an integrated projector output. Such methods may involve using raw presentation data for image processing, including adjustment and/or correction for brightness, color and/or geometry artifacts generated from aspects of the projection surface (such as geometry, texture, color or the like), the surroundings (such as ambient light), the relation of the computer system (or integrated projector output) to the projection surface (such as distance, orientation or the like), and/or the relation of a user/viewer to the projection surface (such as viewing angle, distance or the like). | 04-01-2010 |

| 20100061659 | METHOD AND APPARATUS FOR DEPTH SENSING KEYSTONING - A method for depth sensing keystoning. The method of depth sensing keystoning may include an optical system and electrical devices. The method of depth sensing keystoning may correct for image distortion using depth measurements. | 03-11-2010 |
| 20100302169 | KEYBOARD WITH INCREASED CONTROL OF BACKLIT KEYS - Methods and apparatuses are disclosed that provide increased control of backlit keys for a keyboard. Some embodiments may include controllers within the keyboard that are capable of dynamically programming illumination of the keyboard based upon interaction, where each key of the keyboard may be individually programmed in a dynamic manner. For example, a spell checking function may be executing on a computer system, and as the user types various words, the keyboard may dynamically program the illumination of keyboard controllers such that the next letter of the word being typed is illuminated by the keyboard. Also, different keyboard illumination schemes may be generated based upon mouse movements by the user and/or based upon which application is currently executing. | 12-02-2010 |
| 20100306683 | USER INTERFACE BEHAVIORS FOR INPUT DEVICE WITH INDIVIDUALLY CONTROLLED ILLUMINATED INPUT ELEMENTS - Methods and apparatuses are disclosed that provide user interface behaviors for input devices with individually controlled illuminated input elements. Some embodiments may include receiving a request for input device lighting from a program, determining illumination information for light sources coupled to input elements of an input device based on the request, and dynamically controlling illumination of the light sources based on the illumination information. The illumination information may include brightness, color, and/or duration. The input device may constitute a keyboard with individually controlled illuminated keys. In some embodiments, the illumination may present information related to the program, functionality of input elements, and/or notifications. The request for input device lighting from the program may be based on input selections received from the input device such as illuminating keys on a keyboard that are possible next letters in a word being typed or keys associated with a pressed command key. | 12-02-2010 |
| 20110167289 | BATTERY DISCONNECTION FOR SECURE ASSEMBLY OF COMPUTER SYSTEMS - The disclosed embodiments provide a system that configures a battery for a computer system. During operation, the system disconnects the battery by simulating a fault condition using a safety circuit of the battery. The fault condition may be simulated to facilitate safe assembly of a computer system containing the battery. After assembly is complete, the system enables use of the battery in the computer system by applying external power to the computer system, which resets the safety circuit and reconnects the battery. | 07-07-2011 |
| 20110167290 | CONTROLLING POWER RECEIVED THROUGH MULTIPLE BUS INTERFACES IN A PORTABLE COMPUTING DEVICE - The disclosed embodiments provide a system that enables a portable computing device to receive power through multiple bus interfaces at the same time. When the system senses that a first power source is plugged into a first bus interface in the portable computing device, the system determines whether the first power source is a host or a power adapter. Next, based upon whether the first power source is a host or a power adapter, the system uses a first power manager coupled to the first bus interface to limit a first input current received from the first power source to power the computing device. The system also provides the maximum charging current to a rechargeable battery for the portable computing device by chaining together a second bus interface whether power is present on the second bus interface or not. | 07-07-2011 |

| 20100248064 | THREE DIMENSIONAL SINGLE-CHAMBER FUEL CELLS - The present invention relates to single chamber fuel cells and systems and methods associated with the same. Architectures and materials that allow for high performance, enhanced fuel utilization, mechanical robustness, and mechanical flexibility are described. In some embodiments, multiple fuel cell units are arranged in a single chamber and may be, in some cases, connected to each other (e.g., connected in series, connected in parallel, etc.). Each fuel cell unit can be defined as one or more anode(s), one or more cathode(s), and an electrolyte able to maintain electrical separation between the anode(s) and cathode(s). The multiple fuel cell units are arranged in stacks in some cases. In one set of embodiments, the stacks of fuel cell units can be shaped and/or arranged to enhance the mixing of fuel and oxidant, thus improving distribution of reactants in the reaction zone. For example, the stacks of fuel cells may be arranged as fins within the fuel cell chamber. In addition, the stacks of fuel cells may be porous in some instances. In addition, the stacks of fuel cell units may be arranged to enhance other fluid flow parameters (e.g., residence time, reactant distribution, etc.). In some cases, the enhanced fluid flow may lead to increased fuel utilization and system efficiency. | 09-30-2010 |
