Abstract: A wireless computer data network includes several untethered mobile units that make ad-hoc data connections with an Internet-connected base station using the IEEE-802.11a standard. Each unit includes a radio transceiver fully integrated on a single semiconductor chip. The receiver portion is a double-conversion superheterodyne type, and shares the same intermediate and local oscillator frequencies with a two-stage up-conversion transmitter. Two on-chip synthesizers that each include a voltage-controlled oscillator and phase-locked loop can be operated independently for each conversion stage, or operated in offset mode. External reference frequencies can be injected for voltage-controlled oscillator and phase-locked loop testing, chip characterization, and automatic compensation modeling. Each mobile and base unit can be outfitted with transmit/receive antenna transfer switches, RF-power amplifiers, and low-noise receiver amplifiers to increase operating range.

Abstract: A method, apparatus and system are described for seamlessly sharing I/O devices amongst multiple virtual machines (“VMs”) on a host computer. Specifically, according to one embodiment of the invention, the virtual machine manager (“VMM”) on the host cycles access to the I/O devices amongst the VMs according to a round robin or other such allocation scheme. In order to provide direct access to the devices, the VMM may save the device state pertaining to the currently active VM, store the state in a memory region allocated to the currently active VM, retrieve a device state for a new VM from its memory region and restore the device using the retrieved device state, thus providing the illusion that each VM has direct, full-speed, exclusive access to the I/O device.

Abstract: Systems and methods for object or pattern detection that use a nonlinear support vector (SV) machine are described. In the illustrated and described embodiment, objects or patterns comprising faces are detected. The decision surface is approximated in terms of a reduced set of expansion vectors. In order to determine the presence of a face, the kernelized inner product of the expansion vectors with the input pattern are sequentially evaluated and summed, such that if at any point the pattern can be rejected as not comprising a face, no more expansion vectors are used. The sequential application of the expansion vectors produces a substantial saving in computational time.

Abstract: A manufacturing apparatus, for moving sliders for opening and closing mating zipper elements along the mating zipper elements, includes a roller and a projection. The roller rotates about an axis substantially perpendicular with a path of a film including the mating zipper elements and contacts the film as the film moves in the film path at a speed equal to the speed of rotation of the roller. The projection rotates about an axis at a speed different than the rotational speed of the roller, with the projection rotating into proximity to the moving film along predetermined lengths of the film so as to be contactable with sliders mounted thereon. The projection comes into contact with sliders positioned along the mating zipper elements of the predetermined lengths of film and pushes those sliders along the mating zipper elements to respective registered positions.

Abstract: The import address table of a software module is verified in order to prevent detouring attacks. A determination is made regarding which entries in the IAT must be verified; all of the entries may be verified or some subset of the entries that are critical may be verified. For each external function, the external module containing the external function is loaded, if it is not already loaded. The function address in the exported function table is found. That address is compared to the address for the function in the IAT. Additionally, the external module, in one embodiment, is verified to ensure that it has not been modified. For a delay load IAT, a similar procedure is followed; however the delay load IAT may be periodically checked to ensure that the delay load IAT entries are either valid (indicating that the external function has been bound) or in their initial state (indicating that no binding has yet occurred).

Abstract: Systems and methods provide a user the ability to select three-dimensional virtual objects in a three-dimensional modeling environment using two-dimensional representations of the objects. In broad overview, the invention involves a multidimensional degree of freedom haptic interface that controls a three-dimensional cursor. A user employs the cursor to select an arbitrary point on a three-dimensional virtual object of interest. Through the application of a mathematical transformation, the system displays the cursor at the location of the selected point on the object. The user can manipulate the object by operating the haptic interface. The systems and methods provide the user with the possibility of editing the selected virtual object. In one embodiment, editing includes sculpting the object. When the user releases the object after manipulation is completed, the cursor is relocated to the position the cursor would have had had the manipulations been applied to the cursor directly.
