The present invention discloses a novel, user-wearable system for monitoring the oxygen concentration, or oxygenation trend, in the tissue of a subject undergoing aerobic stress. The system comprises a lightweight detector, worn against the skin surface of the subject, at the site being monitored. The system further includes wearable power pack and display means for displaying information indicative of the metabolic condition of the region being monitored. The detector preferably employs a continuous wave spectrophotometer having one or more sources of electromagnetic radiation with wavelengths between about 760 and 800 nanometers directed into the tissue of the subject. The detector utilizes photon migration to detect the portion of the transmitted radiation arriving at an adjacent skin region. The present invention also discloses methods for displaying the aerobic metabolic condition of a subject.

The invention is a method for detecting and measuring T-cell receptor (TCR) repertoires from mammalian lymphocytes. The method is based on the use of the multiple sets of unique primers to amplify 22 regions of the TCR Vβ region and thereby detect clonal expansions related to antigen stimulation of the immune system. Kits containing sets of primers and specialized analytical statistical software for use in determining clonal expansion in humans and mice are disclosed. The reliability, efficiency and short assay time in using the method is well suited to monitoring immune response to vaccination and therapeutic treatments for immune disorders.

Techniques disclosed herein provide for assisted context determination through the use of one or more servers remote to a mobile device. The one or more servers can receive location and/or other information from the mobile device and select, from a list of possible activities, a smaller list of activities a mobile device user is likely engaged in. The one or more servers can return the smaller list to the mobile device, which can use the smaller list to make a faster context determination. In creating the smaller list, the one or more servers can utilize information regarding a region in which the mobile device is located, which can be updated and modified using information received from mobile devices. Furthermore, the one or more servers can gather and share information from nearby mobile devices, enabling a mobile device to use information from nearby mobile devices to facilitate a context determination.

An apparatus and method for locating mobile terminals is disclosed. A base station transmits a radio signal to mobile terminals located in a specific area, and generates- auxiliary location information for locating mobile terminals from a radio signal received from the terminals.

A modem, or a communication system, in its transmission section, has signal-formatting circuitry followed by circuitry for insertion of a sequence of pilot symbols into a sequence of data symbols outputted by the formatting circuitry. Placement of the insertion circuitry after the formatting circuitry permits a variety of formatting options without effecting the sequence of pilot symbols that serves as a time reference useful in detection of a signal transmitted by the modem. The reception section of the modem is equipped correspondingly to process a received composite signal of data symbols having a prescribed format and a sequence of pilot symbols. The reception section extracts the sequence of pilot symbols from the composite signal, and employs the pilot symbols to develop a time base for operation of circuitry for decoding the format of the received composite signal to extract data from the composite signal.

An efficient determination of a click distance value is made for each document in a corpus of documents from data included in a locally-stored inverted index. The click distance is measurement of the number clicks or user navigations from a first document on the network to another document. Specialized words are included in the locally-stored inverted index. The specialized words relate source documents to a set of target documents. A click distance is assigned to a source document when an inverted index is queried for the corresponding set of target documents according to a query that passes in one of the specialized words. The process is repeated for each document in the corpus of documents.
