Sequestering of glycoprotein molecules and oligosaccharide moieties in lipo-glycoprotein membranes and micelles

Spontaneous formation of a coherent membrane at the interface between a non-polar liquid and an aqueous solution of glycoprotein can be used to separate proteins and carbohydrates from tissue fluid and other complex mixtures. When volatile hydrocarbons are used to induce membrane formation, evaporation of organic and aqueous solvents leaves behind a delicate film or powder. The method for extracting glycoprotein from solution and sequestering it in floating membranes can be used to study environmental conditions or to remove carbohydrates from proteins in the tissues of living organisms. This technique can also be used for detecting proteins in solutions.

Sub-symbol parallel interference cancellation

Reduction of multiple access interference, in one example for asynchronous CDMA systems using long codes. In one aspect, parallel interference cancellation (PIC) implements a decoupled estimate, preferably non-linear and applied at chip intervals. According to another aspect, interference is cancelled using a technique that estimates bits for a symbol by interpolating signature waveforms for users to a common sampling lattice of the received data. According to another aspect, multi-stage, hybrid multi-stage, and reconfigurable recursive multi-stage, multi-user detection architectures and corresponding processes are provided.

Programmable peripheral switch

A peripheral switch is electrically interposed between a peripheral device and a plurality of computing devices respectively coupled to host computer ports. The peripheral switch includes host computer port state sensing means for determining a state of each host computer port and providing a communication path to the peripheral device from a host computer port at a state indicative of a server computer being coupled thereto. The peripheral switch further includes local handshaking means for simulating communications from a server computer to peripheral device if none of host computer ports are determined to be coupled to a server computer.

Method and system for finding similar records in mixed free-text and structured data

A technique for data mining where the available data contains both structured as well as unstructured (free-text) data. Performing separate analysis on these different sources of data does not fully exploit the available information (e.g. clustering records without regard to narratives can match reports of total electrical failure with human factors problems). The application describes one approach to combining the information available from all of these different types of data together to get a single “similarity” score. The importance of picking tools appropriate to the types of data in hand is also stressed.

Multi-rate spectrum analyzer with adjustable time frequency

A multi-rate spectral analyzer receives a data sequence through a tapped delay line (510) onto a plurality of filter channels, each of which includes a first decimator (520), a polyphase filter (530), and a second decimator (540). Each filter channel is coupled to a transform processor (550) which modulates the frequency response of the polyphase filters to a plurality of identical bandpass filters spaced evenly at intervals. The transform processor (550) outputs a plurality of time series representative of the frequency component for each of the corresponding filter channels. By choosing a prototype filter order to be much larger than the number of filter channels, the effects of aliasing in the output are greatly reduced. The reduction in aliasing further allows, by prudent selection of the two decimators, for fractional temporal overlap to be implemented in the spectral estimates.
