Respiration Motion Detection and Health State Assesment System

A wearable platform embodied in a belt or flattened patch-like central body shaped to conform to the abdomen provides physiological monitoring of soldiers during field operations or trauma victims at accident sites and makes health state assessments. The platform includes sensors for heart rate, body motion, respiration rate and intensity, and temperature and further contains a microprocessor and short range transmitter. The respiration sensor uses conductive ink in a novel manner. A small square of the ink is coated on an arched structure so that flexing of the arch either to increase or decrease its radius of curvature modifies the resistance of the structure. This is utilized to set the unstressed resistance of the arch structure and to allow a greater range of resistance values capable of measuring distortions in different deformations of the arch. The respiration sensor supplements the motion information provided by an accelerometer sensor.

Real-time multicast peer-to-peer video streaming platform

A peer-to-peer platform makes use of a streaming agent running at each peer. The streaming agent causes a peer to receive chunks of content from different neighboring peers, store some of the chunks in a local cache, and distribute those cached chunks to neighboring peers. Delivering next generation broadcasts (e.g., as streams of live audio and digital media) of any size utilizing the Internet is achieved. Users can view a live or prerecorded stream of a broadcast through an integrated media player, or can replay a broadcast through an integrated, intelligent archiving service. Use of the platform reduces bandwidth demands on live streaming and archiving services to a level where it is sustainable within a profitable business model to offer the services for at most a negligible fee.

The invention also indicates preferred methods for specific compression and decompression of particular data formats such as digital video, 3D textures and image data using a combination of novel lossy and lossless compression algorithms in block or span addressable formats. To improve latency and reduce performance degradations normally associated with compression and decompression techniques, the MemoryF / X Technology encompasses multiple novel techniques such as: 1) parallel lossless compression / decompression; 2) selectable compression modes such as lossless, lossy or no compression; 3) priority compression mode; 4) data cache techniques; 5) variable compression block sizes; 6) compression reordering; and 7) unique address translation, attribute, and address caches. The parallel compression and decompression algorithm allows high-speed parallel compression and high speed parallel decompression operation.

Late reverberation-based synthesis of auditory scenes

A scheme for stereo and multi-channel synthesis of inter-channel correlation (ICC) (normalized cross-correlation) cues for parametric stereo and multi-channel coding. The scheme synthesizes ICC cues such that they approximate those of the original. For that purpose, diffuse audio channels are generated and mixed with the transmitted combined (e.g., sum) signal(s). The diffuse audio channels are preferably generated using relatively long filters with exponentially decaying Gaussian impulse responses. Such impulse responses generate diffuse sound similar to late reverberation. An alternative implementation for reduced computational complexity is proposed, where inter-channel level difference (ICLD), inter-channel time difference (ICTD), and ICC synthesis are all carried out in the domain of a single short-time Fourier transform (STFT), including the filtering for diffuse sound generation.

Real time video game uses emulation of streaming over the internet in a broadcast event

In a broadcast application on a client-server network the streaming is emulated of animation data over the Internet to a large number of clients. The animation is considered a sequence of states. State information is sent to the clients instead of the graphics data itself. The clients generate the animation data itself under control of the state information. The server and clients communicate using a shared object protocol. Thus, streaming is accomplished as well as a broadcast without running into severe network bandwidth problems. This approach is used to map a real life event, e.g., a motor race, onto a virtual environment in order to let the user participate in a virtual race against the real life professionals, the dynamics of the virtual environment being determined by the state changes sent to the user.

System and method for performing compound vector operations

A processor particularly useful in multimedia applications such as image processing is based on a stream programming model and has a tiered storage architecture to minimize global bandwidth requirements. The processor has a stream register file through which the processor's functional units transfer streams to execute processor operations. Load and store instructions transfer streams between the stream register file and a stream memory; send and receive instructions transfer streams between stream register files of different processors; and operate instructions pass streams between the stream register file and computational kernels. Each of the computational kernels is capable of performing compound vector operations. A compound vector operation performs a sequence of arithmetic operations on data read from the stream register file, i.e., a global storage resource, and generates a result that is written back to the stream register file. Each function or compound vector operation is specified by an instruction sequence that specifies the arithmetic operations and data movements that are performed each cycle to carry out the compound operation. This sequence can, for example, be specified using microcode.
