Abstract: A visible light communication system identifies the location of a mobile device using light intensities corrected by mobile device orientation. This location can be used to generate a dynamic cluster of visible light transmitters about the mobile device providing improved “handoff” between transmitters and reduced shadowing.

Abstract: A computer architecture for graph processing employs a high-bandwidth memory closely coupled to independent processing elements for searching through a graph using a first set of processing elements operating simultaneously to determine neighbors to a current frontier and second processing elements operating simultaneously to determine a next frontier, this process being repeated to search through graph nodes.

Abstract: A computer architecture for graph-traversal provides a processor for bottom-up sequencing through the graph data according to vertex degree. This ordered sequencing reduces redundant edge checks. In one embodiment, vertex adjacency data describing the graph may be allocated among different memory structures in the memory hierarchy to provide faster access to vertex data associated with vertices of higher degree reducing data access time. The adjacency data also may be coded to provide higher compression in memory of vertex data having high vertex degree.

Abstract: A neural network processor architecture provides decompression circuitry that can exploit patterns of data in kernel weights of a convolutional neural net as flattened to a vector, the compression allowing reduced kernel data storage costs including on-chip-storage.

Abstract: A virtual touchscreen for mobile devices provides a touchscreen area displaced to a side of the display to eliminate problems of a finger blocking the display during normal touchscreen operation. The virtual touchscreen may be monitored by a sensor system looking edgewise from a housing of the mobile device employing as few as two displaced photodetectors and a correspondingly oriented light source constrained to sensitivity within a narrow fan-shaped light-sensing plane. Extraction of the spatial location of a finger touch within this touchscreen area may be performed by a model of reflected light signals of a finger in different locations calibrated to environmental parameters of finger reflectivity and background reflectivity by a simple calibration process.

Abstract: A computer architecture provides for multiple processing elements arranged in logical rows and columns to share local memory associated with each column and row. This sharing of memory on a row and column basis provides for efficient matrix operations such as matrix multiplications such as can be used in a variety of processing algorithms to reduce dataflow between external memory and the local memories and/or to reduce the size of necessary local memories for efficient processing.
