Title: Voice activity detector
Inventor: FIRAS JABLOUN
IPC: G10L25/78
Filed: 2005-05-09
Abstract: A voice activity detection method comprising the steps of (a) Estimating in a noise power estimator the noise power within a signal having a speech component and a noise component, and (b) Calculating a likelihood ratio for the presence of speech in the signal from the estimated power of noise signals from step (a) and a complex Gaussian statistical model. The advantage of this technique is that it does not require a previously calculated noise power estimate (obtained from a previously calculated likelihood ratio) and therefore any errors are not re-iterated in a feedback loop and consequently do not increase.

Title: An optical mouse with an optical element which has at least one electrically conductive surface
Inventor: VOOK DIETRICH W
IPC: G06F3/03
Filed: 2005-05-25
Abstract: A motion sensor for an optical mouse (1, fig. 1) which sensor has: an optical element (7, fig. 1) having at least one electrically conductive surface 210. This eclectically conductive surface 210 may be plastics containing a conductive polymer, such as polythiophene. Alternatively, electrically conductive surface may be a coated surface layer 210 that for example contains indium tin oxide.

Title: Semiconductor device and method for generating sense signal
Inventor: NAKAI TSUTOMU
IPC: G11C16/28
Filed: 2004-07-30
Abstract: A semiconductor device comprising a first cascode circuit including a first current mirror for amplifying a reference current flowing through the data line of a reference cell and a second current mirror generating a first potential by the reference current; and a second cascode circuit including a third current mirror for amplifying a core cell current flowing through the data line of a core cell and a transistor receiving a reference current value from the second current mirror as a gate voltage and generating a second potential from the difference between the core cell current and the reference current. Since a second potential is generated from the difference between the core cell current and the reference current, the second potential can be generated over the full range of the power supply potential and the ground potential. Consequently, the amplitude range of the power supply voltage can be used effectively and even a very small current margin can be sensed.
