Abstract: The present invention includes an apparatus and method for determining cell coverage in a region with reduced in-field propagation measurements comprising: obtaining geographical features of the region; predicting the number of measurements required to accurately characterize its path loss; determining the path loss prediction accuracy of wardriving and crowdsourcing by oversampling a suburban and a downtown region from cell measurements that comprise signal strength and global positioning system coordinates; and using statistical learning to build a relationship between these geographical features and the measurements required, thereby reducing the number of measurements needed to determine path loss accuracy.

Abstract: The present invention describes a speech enhancement method using microphone arrays and a new iterative technique for enhancing noisy speech signals under low signal-to-noise-ratio (SNR) environments. A first embodiment involves the processing of the observed noisy speech both in the spatial- and the temporal-domains to enhance the desired signal component speech and an iterative technique to compute the generalized eigenvectors of the multichannel data derived from the microphone array. The entire processing is done on the spatio-temporal correlation coefficient sequence of the observed data in order to avoid large matrix-vector multiplications. A further embodiment relates to a speech enhancement system that is composed of two stages. In the first stage, the noise component of the observed signal is whitened, and in the second stage a spatio-temporal power method is used to extract the most dominant speech component.

Abstract: An integrated circuit has a first scan cell segment, a second scan cell segment connected to one or more hidden content, and a scan cell circuit connected to the first scan cell segment and the second scan cell segment. The scan cell circuit alternatively provides access to the first scan cell segment and the second scan cell segment based on a state of the scan cell circuit.

Abstract: Various integrated circuits protect hidden content e.g., embedded instruments, keys, data, etc.) using scan cell circuit(s). For example, a first scan cell circuit is connected to the hidden content, and a second scan cell circuit is connected to the first scan cell circuit forming all or part of a serial data path. The first scan cell circuit provides access to the hidden content whenever the first scan cell circuit is in a first specified state and prevents access whenever the first scan cell circuit is in a different state. The first scan cell circuit does not interrupt the serial data path when the first scan cell circuit is in the different state. The second scan cell circuit changes an operational characteristic of the first scan cell circuit whenever the second scan cell circuit is in a second specified state. In some cases, the second scan cell circuit can be eliminated.

Abstract: Methods, apparatuses, and computer program products for squaring an operand include identifying a fixed-point value with a fixed word size and a substring size for substrings of the fixed-point value, wherein the fixed-point value comprises a binary bit string. A square of the fixed-point value can be determined using the fixed point value, the substring size, and least significant bits of the fixed-point value equal to the substring size.

Abstract: A system and method for providing multi-dimensional context-aware adaptation in vehicular networks is disclosed. The system comprises a collection module, a context resolving module, a parameter determination module and a distribution module. The collection module collects context data describing a context in a communication environment. The context resolving module resolves the context data to a matching historical context and determines one or more historical context groups associated with the matching historical context. The parameter determination module determines a subset of operating parameters from the one or more historical context groups. The distribution module distributes the subset of operating parameters to a network stack communication module.

Abstract: A system includes a camera and a projector for capturing spatial detail having resolution exceeding that afforded by the imaging optics, and recovering topographic information lost to the projective nature of imaging. The projector projects a spatial pattern onto the scene to be captured. The spatial patterns may include any pattern or combination of patterns that result in complex sinusoidal modulation. Spatial detail such as texture on the objects in the scene modulate the amplitude of the spatial pattern, and produce Moiré fringes that shifts previously unresolved spatial frequencies into the camera's optical passband. The images may be demodulated, and the demodulated components may be combined with the un-modulated components. The resulting image has spatial detail previously inaccessible to the camera owing to the band-limited nature of the camera optics. A spatial pattern may also be projected and received by the camera to estimate topographic information about the scene.

Based at least on the position or motion of the one or more points of the body during the movement, the processor calculates a first one or more curves indicative of a first force between a surface and at least a first portion of the body, and calculates a second one or more curves indicative of a second force between the surface and at least a second portion of the body. The processor further predicts a force applied to the surface by the body during the movement by combining the first and second one or more curves.

The second digital image captures a spatially shifted version of the first digital image. The first PTF and the second PTF are compared and a spatial shift of the second image to the first image is determined.
