Abstract: An interactive surface computer with a switchable diffuser layer is described. The switchable layer has two states: a transparent state and a diffusing state. When it is in its diffusing state, a digital image is displayed and when the layer is in its transparent state, an image can be captured through the layer. In an embodiment, a projector is used to project the digital image onto the layer in its diffusing state and optical sensors are used for touch detection.

Abstract: Methods and devices for providing a user input to a device through sensing of user-applied forces are described. A user applies forces to a rigid body as if to deform it and these applied forces are detected by force sensors in or on the rigid body. The resultant force on the rigid body is determined from the sensor data and this resultant force is used to identify a user input. In an embodiment, the user input may be a user input to a software program running on the device. In an embodiment the rigid body is the rigid case of a computing device which includes a display and which is running the software program.

Abstract: Computerized methods and systems for controlling a peripheral device based, at least in part, upon remote user instructions are provided. Upon receiving a communication from the peripheral device (e.g., using a USB port), a computing device recognizes the peripheral device. Next, a command manifest is automatically generated that includes one or more commands that correspond to at least one controllable function of the peripheral device. In addition, the command manifest may be communicated to a remote-user device configured to present the commands to the remote user, typically, by displaying a representation of the commands at a user interface associated therewith. A transmission that includes content indicating one or more of the commands may be received from the remote-user device. Consequently, commands are determined from content and transferred to the peripheral device, which performs the corresponding controllable functions.

Abstract: A method for tracking a moving platform (MP) wherein the MP uses an on-board navigation system (NS). Data provided by the navigation system on board the moving platform (MP) is merged with data obtained using a tracking system that tracks the MP from another location. A typical navigation system on board the moving platforms is an inertial navigation system (INS). State data of one or more MP is sent to a processing facility and state data of one or more electromagnetic tracking (EMT) is collected by one or more processing facility. The collected states data from the sources are processed, using the one or more processing facilities for calculating tracking data are used to direct one or more antennas for MP tracking. The state data from one or more MP's are sent using a communications channel.

Abstract: A printer, scanner device and methods for using same are described herein. A printer device may include a dedicated input that, when actuated, generates and sends a request to a computer for known data or a predetermined print job, e.g., schedule information from a personal information management (PIM) application. A scanner device may include another dedicated input that, when actuated, automatically scans a document fed to the device by the user and sends the scanned image to IM (or other) software on a computer, bypassing the need to manipulate the scanned image using scanner software. The device may be used with printed metapaper, which includes a barcode or other indicia identifying the metapaper and corresponds to a stored template image of the metapaper. When the metapaper is rescanned, the scan can be compared to the stored template information to identify changes and synchronize the changes with the IM software.

Abstract: The photodiode cell (1) includes at least one photosensitive area (3), made in a silicon semiconductor substrate (2), for receiving light, particularly coherent light, and a passivation layer and a dielectric layer (4). The passivation layer is composed of at least a first silicon oxide layer (5) and a second nitride layer (6), made on the photosensitive area. The second nitride layer is made with a thickness within a determined margin, so as to be situated in a zone with the most constant possible light reflectivity independently of the thickness of the first layer. An etch (7) can be performed on one portion of the dielectric layer (4) or on the first layer (5) corresponding to half of the reception surface of the photosensitive area in order to obtain a reflectivity percentage mean of the light to be sensed by the photodiode cell.

Abstract: New methods of generating optimal inversion pulses and adiabatic pulses in magnetic resonance imaging are disclosed. Trajectories, maximum sweep rates, and velocity profiles are used in defining an optimal pulse, over support regions. Adiabatic pulses are optimized by using the trajectory as a constraint of optimization, but selecting trajectories with velocity profiles, without using the adiabatic condition as a constraint for optimizing the velocity profile. A method or inverting MR spins substantially, independently of the pulse duration, by selecting a transition width between 1.4 and 1.9 and dividing that width by the pulse duration is disclosed; and A new method of inverting adiabatic, MR, amplitude modulated spins, with a trajectory defined by sin .alpha./cos .alpha., where .alpha.<0.9 and at least 50% of the trajectory is outside, in a z-x rotating frame of reference that rotates at the instantaneous frequency of the RF pulse is also taught.
