Abstract: A low-power transmission system for periodically transmitted data communicates the periodic data as an interval between two transmitted anchor symbols when the transmitter and associated circuitry are shut down. Meaningful power savings for short data words is obtained by use of a star topology allowing elimination of the receiver power consumption. Multi-bit anchor symbols provide improved error detection and the separation of simultaneous transmission from multiple transmitters by a single receiver.

Abstract: An optical coherence tomography system for ophthalmic use identifies tissue by selected laser heating of that tissue at reduced power levels decreasing background noise to boost signal-to-noise ratio allowing detection of minute changes in thermal expansion caused by that heating at clinically acceptable levels.

Abstract: Medical foods containing glycomacroprotein and additional supplemented amounts of arginine, leucine, and optionally other amino acids, such as tyrosine, are disclosed. The medical foods can be used to provide the complete protein requirements for patients having metabolic disorders such as phenylketonuria.

Abstract: A mutant strain of the bacterium Clostridium botulinum having an inactivated botulinal neurotoxin gene is disclosed. The mutant strain contains an artificially created and inserted modified intron vector between nucleotides 580 and 581 of the sense strand of the gene. The mutant strain can be used in microbiological challenge testing of foods and food processing methods.

Abstract: A capacitive touch sensor is provided, The capacitive touch sensor includes a plate having an upper surface and lying in a plate plane. A generally planar, first electrode is spaced from the plate along an axis generally perpendicular to the upper surface of the plate. The first electrode movable with respect to the plate in response to a force. A plurality of second electrodes are interconnected to the plate and circumferentially spaced about the axis. Each of the plurality of the second electrodes has a corresponding differential capacitance with the first electrode. The differential capacitances between the first electrode and the plurality of second electrodes vary in the response to the movement of the first electrode.

Abstract: The present invention provides N-benzyl-3-sulfonamidopyrrolidines and related compounds, as well as pharmaceutical compositions and sanitizing compositions containing the same. The compounds and compositions are useful as antibiotic agents. Methods for making and using the compounds and compositions are also described.

Abstract: A method of differentiating embryonic stem cells into neural and motor cells is disclosed. In one embodiment, the invention comprises culturing a population of cells comprising a majority of cells that are characterized by an early rosette morphology and are Sox1?/Pax6+ in the presence of FGF2, FGF4, FGF8, FGF 9, or RA wherein the cells are characterized by an neural tube-like rosette morphology and are Pax6+/Sox1+.
