Abstract:

A dual-mode projection apparatus has a projection module for projecting an image onto a projection surface. An image sensor module captures images of the projection surface and determines spatial and temporal characteristics of a visible light spot superimposed on the projection surface. A communications module transmits the spatial and temporal characteristics of the visible light spot to a remote device for remote control of the device based on the spatial and temporal characteristics of the visible light spot.

International Classification:

G06F 15/16

US Classification:

709232, 709233

Abstract:

An ISP-friendly rate allocation system and method that reduces network traffic across ISP boundaries in a peer-to-peer (P2P) network, Embodiments of the system and method continuously solve a global optimization problem and dictate accordingly how much bandwidth is allocated on each connection. Embodiments of the system and method minimize load on a server in communication with the P2P network, minimize ISP-unfriendly traffic while keeping the minimum server load unaffected, and maximize peer prefetching. Two different techniques are used to compute rate allocation, including a utility function optimization technique and a minimum cost flow formulation technique. The utility function optimization technique constructs a utility function and optimizes that utility function. The minimum cost flow formulation technique generates a minimum cost flow formulation using a bipartite graph have a vertices set and an edges set. A distributed minimum cost flow formulation is solved using Lagrangian multipliers.

US Classification:

345157, 345158, 353 30

Abstract:

A light pointer apparatus has a light source module for projecting a light beam onto a surface. The light pointer apparatus also has an image sensor module and a transmitter module. The image sensor module detects a position in the surface of a visible light spot generated by the projected light beam striking the surface. The transmitter module transmits the position of the visible light spot to a remote device for remote control of a device.

International Classification:

G06F 3/042

US Classification:

345175, 178 1809

Abstract:

Optical position input systems and methods determine positions of at least one pointing objects within an active touch area. At least three imager modules form images of at least one pointing objects within the active touch area. A processor computes a position of each of the at least one pointing object based upon the images formed by the at least three imager modules.

International Classification:

H01L 21/00

US Classification:

438 29, 257E21548

Abstract:

A photon collector has a reflecting metal layer to increase photon collection efficiency in a solid state imaging sensor. The reflecting metal layer reflects incident light internally to a photosensor. A plurality of photon collectors is formed in a wafer substrate over an array of photosensors. The photon collector is formed in an opening in an insulating layer provided over each photosensor.

International Classification:

H04L 12/56

US Classification:

370390

Abstract:

Described is a distributed peer-assisted multicast content delivery system (e.g., a multiparty conferencing application) that uses an adaptive link rate control protocol to discover and adapt to an arbitrary topology quickly and converge to efficient link rate allocations allowed by an underlying network. Link rates are regularly obtained and used to determine trees for sending packets to other nodes. Network coding is used to implement data multicast so that mixtures (i.e., linear combinations) of the packets are transmitted in the network. The redundant packets may be differentiated from non-redundant (“innovative”) packets such that network conditions may be measured by link innovation and/or session innovation.
