Integrated resonating gyro accelerometer in a semiconductor substrate

US Patent 7,929,143
April 19, 2011
An integrated interferometric gyroscope and accelerometer device. An example device includes a cantilever beam, a package having a post connected to one end of the beam, a piezoresistor driver, a piezoresistor sensor, and a semiconductor interferometric optical gyro. The piezoresistor driver is incorporated within the beam at a first area proximate to the post. The driver electro-thermally resonates the beam. The piezoresistor sensor is incorporated within the beam at the first area. The sensor piezoresitively senses a signal that relates to an acceleration force out-of-plane of the beam. The semiconductor interferometric optical gyro is also incorporated within the beam at a second area of the beam. The gyro senses rotational motion about an axis approximately equivalent to the acceleration force out-of-plane of the beam. The gyro includes a waveguide, a laser source and a light detector. The beam is formed from a semiconductor substrate.

Systems and methods for communication to a gimbal mounted device

US Patent 7,928,895
April 19, 2011
A system and method wirelessly communicates signals between a device on a gimbal and a stationary transceiver. An exemplary system has a gimbal with a moveable portion, a device affixed to the moveable portion, a gimbal transceiver coupled to the moveable portion, and a stationary transceiver, wherein the gimbal transceiver and the stationary transceiver are configured to communicate with each other using a wireless signal.

Integrated position light overlap baffles

US Patent 7,918,592
April 5, 2011
A position light including a base that is configured to attach to an aircraft. The base having an extruded overlap baffle. A first LED is coupled to the base underneath the overlap baffle. A circuit card is also coupled to the base and is extended over the first LED toward the over flap baffle. A second LED coupled to a circuit card. The extended overlap baffle and the extended circuit card block visible light emitting from the first LED.

Method and system for automatically preserving persistent storage

US Patent 7,917,717
March 29, 2011
Computer-based methods, techniques, and systems for automatically protecting a storage device from unwanted alterations are provided. Example embodiments provide a Disk Access Redirection System, which includes a Redirection Driver, an Available Space Table (“AST”), a Protected Space Redirection Table (“PSRT”), and optionally an Unprotected Space Table (“UST”). The Redirection Driver is installed and registered with the computer operating system so that it can intercept storage device access requests (such as a disk read/write). When a storage access request for a read or write is sent, the request is intercepted by the Redirection Driver, transparent to the code that invokes the storage access request. The Redirection Driver uses the AST, PSRT, and optionally the UST, to allocate available storage space for redirected write requests, redirect write requests for protected areas of the storage device, and redirect read requests when the read request specifies a storage location that has been previously redirected.

Apparatus for remotely controlling computers

US Patent 7,917,235
March 29, 2011
An apparatus for remotely operating a computer using a combination of voice commands and finger movements. The apparatus includes a microphone and a plurality of control elements in the form of touch-sensitive touchpads and/or motion-sensitive elements that are used to operate the computer and to move an on-screen cursor. At least one touchpad is used to selectively switch between a command-mode of operation in which the computer interprets spoken words as commands for operating the computer and any software applications being used, and a text-mode of operation in which the computer interprets spoken words literally as text to be inserted into a software application. The apparatus is ergonomically designed to enable it to be easily worn and to enable a user to operate a computer from a standing, sitting or reclining position. The apparatus can be used to operate a computer for traditional computing purposes such as word processing or browsing the Internet, or for other purposes such as operating electronic devices such as a television and/or other household appliances. The apparatus eliminates the need for a keyboard and a mouse to operate a computer. In addition, the apparatus can be used as a telephone.

System and method of teaching and learning mathematics

US Patent 7,914,287
March 29, 2011
Numero Cubes and the Whole Number System are disclosed. In one embodiment, the system may comprise cubes, pegs, magnets, dividers, shafts, and a number placement panel. The shafts may comprise individual marks representing the base ten number system. The system may provide a method of learning mathematics through a cognitively authentic learning experience in constructing and building numbers.

System and method for positioning in configured environments

US Patent 7,916,074
March 29, 2011
The present invention relates to a system and method for providing location determination in a configured environment in which Global Navigation Satellite System Signals may not be available. In this regard, local beacon systems generate spread spectrum CDMA signals that are received by spectral compression units that derive physically meaningful observations without a requirement for correlation of the intercepted energy by means of the known spreading codes. The invention can coexist with communication assets already in place, and the design allows for self calibration, which simplifies installation and usage. The invention has utility in applications in which GNSS signals are unavailable or limited, for example, in warehouse inventory management, in search and rescue operations and in asset tracking in indoor environments.

Predicted path selection system and method for hazard coding in selectively constrained aircraft con

US Patent 7,912,594
March 22, 2011
A surveillance system detects potential hazards and alerts the pilot to them. The alerts can be modified to indicate proximity to the predicted path of the aircraft. An autopilot receives instructions from a flight management system (FMS) regarding a planned path and is subject to constraints preempting the planned path. The surveillance system selects which of the planned and a constrained path will be followed for alerting and hazard coding purposes. Means are disclosed to determine when the constrained path will be followed by evaluating the current position of an aircraft, the planned path, and the constraint data.

Sharing account information and a phone number between personal mobile phone and an in-vehicle embed

US Patent 7,912,512
March 22, 2011
A phone embedded within a vehicle for automatically using a service plan of a proximate personal mobile phone. The embedded phone includes an internal communication component that detects the presence of the personal mobile phone, and receives a mobile subscriber identification number from the detected phone. The embedded phone also includes an external communication component that sends the received mobile subscriber identification number to a wireless network authority, and receives an authentication request to the personal mobile phone via the embedded phone. The internal communication component sends the authentication request to the personal mobile phone. The personal mobile phone generates an authentication signal, and the external communication component sends the authentication signal to the wireless network authority.
