Title: Method and device for converting thermal energy into mechanical energy
Inventor: HAUER THOMAS
IPC: F01K27/00
Filed: 2008-08-21
Abstract: When converting thermal energy into mechanical energy by means of a working medium which contains a mixture of at least two materials having different boiling points and condensation points, is fed to a condenser (8), and is condensed therein, the problem is that the condensation pressure in the condenser increases and the efficiency for generating the mechanical energy thus decreases because the mixture of materials is separated into a liquid phase and a vapor phase upstream of the condenser. In order to prevent this from happening, according to the invention, the liquid phase of the working medium is mixed with the vapor phase of the working medium before or while the working medium is condensed in the condenser (8), thus once again creating a homogeneous mixture of materials which condenses at a lower pressure than the separated working medium, thereby preventing loss of efficiency. The invention preferably applies to the use of thermal energy from low-temperature sources such as geothermal fluids, industrial waste heat, or waste heat from internal combustion engines.

Title: Robust two microphone noise suppression system
Inventor: ZUREK ROBERT A
IPC: H04B1/10
Filed: 2008-10-01
Abstract: A system, method, and apparatus for separating speech signal from a noisy acoustic environment. The separation process may include directional filtering, blind source separation, and dual input spectral subtraction noise suppressor. The input channels may include two omnidirectional microphones whose output is processed using phase delay filtering to form speech and noise beamforms. Further, the beamforms may be frequency corrected. The omnidirectional microphones generate one channel that is substantially only noise, and another channel that is a combination of noise and speech. A blind source separation algorithm augments the directional separation through statistical techniques. The noise signal and speech signal are then used to set process characteristics at a dual input noise spectral subtraction suppressor (DINS) to efficiently reduce or eliminate the noise component. In this way, the noise is effectively removed from the combination signal to generate a good qualify speech signal.
