IPC: G10L19/14
Filed: 2007-06-19
Abstract: A vocoder and method transcodes Mixed Excitation Linear Prediction (MELP) encoded data for use at different speech frame rates. Input data is converte (100) into MELP parameters such as used by a first MELP vocoder. These parameters are buffered (102) and a time interpolation (104) is performed on the parameters with quantization to predict spaced points. An encoding function (106) is performed on the interpolated data as a block to produce a reduction in bit-rate as used by a second MELP vocoder at a different speech frame rate than the first MELP vocoder.

Title: Hybrid cycle rotary engine
Inventor: SHKOLNIK ALEXANDER C
IPC: F01C11/00
Filed: 2007-08-01
Abstract: An internal combustion engine includes in one aspect a source of a pressurized working medium and an expander. The expander has a housing and a piston, movably mounted within and with respect to the housing, to perform one of rotation and reciprocation, each complete rotation or reciprocation defining at least a part of a cycle of the engine. The expander also includes a septum, mounted within the housing and movable with respect to the housing and the piston so as to define in conjunction therewith, over first and second angular ranges of the cycle, a working chamber that is isolated from an intake port and an exhaust port. Combustion occurs at least over the first angular range of the cycle to provide heat to the working medium and so as to increase its pressure. The working chamber over a second angular range of the cycle expands in volume while the piston receives, from the working medium as a result of its increased pressure, a force relative to the housing that causes motion of the piston relative to the housing.

Inventor: KANAI TOMOMI
IPC: G01N27/12
Filed: 2007-06-21
Abstract: A hydrogen gas concentration sensor which comprises a base and hydrogen-detecting films which are adjacent to one another and formed on the base. These hydrogen-detecting films each comprises a thin film layer and a catalyst layer formed on the surface of the thin film layer. Upon contact with hydrogen gas, each catalyst layer reversibly hydrogenates the thin film based on photocatalysis to reversibly change the electrical resistance thereof. These thin film layers differ in resistance change sensitivity to hydrogen gas concentration changes and in hydrogen gas concentration determination range. Thus, the hydrogen gas concentration sensor determines the concentration of hydrogen gas with a thin film layer having a higher sensitivity when the hydrogen gas concentration is low and with a thin film layer having a wider determination range when the hydrogen gas concentration is high.
