Title: Silicon carbide field conrolled bipolar switch
Inventor: SINGH RANBIR
IPC: H01L21/337
Filed: 1998-03-20
Abstract: A field controlled bipolar switch having a bulk single crystal silicon carbide substrate of a first conductivity type having an upper surface and a lower surface. A first epitaxial layer of a second conductivity type silicon carbide is formed upon the upper surface of the substrate. A second epitaxial layer of the second conductivity type silicon carbide is formed on the first epitaxial layer of silicon carbide. A plurality of regions of a third conductivity type silicon carbide are formed in the second epitaxial layer to form a gate grid in the second epitaxial layer. A third epitaxial layer of the second conductivity type silicon carbide is formed on the second epitaxial layer and a fourth epitaxial layer of the second conductivity type silicon carbide is formed upon the third epitaxial layer. The fourth epitaxial layer has a higher carrier concentration than is present in the first, second and third epitaxial layers. A first ohmic contact is formed upon the fourth epitaxial layer and a second ohmic contact is formed on the lower surface of the substrate. An ohmic gate contact is connected to the gate grid for pinching off the flow of current between the first ohmic contact and the second ohmic contact when a bias is applied to the ohmic gate contact.

Title: Digital filter design method and apparatus for noise suppression by spectral substraction
Inventor: ERIKSSON ANDERS
IPC: G10L21/0208
Filed: 2000-08-23
Abstract: A digital filter design apparatus for noise suppression by spectral subtraction includes a first spectrum estimator for determining a high frequency resolution noisy speech power spectral density estimate from a noisy speech signal block. A second spectrum estimator determines a high frequency resolution background noise power spectral density estimate from a background noise signal block. Averaging units form a piece-wise constant noisy speech power spectral density estimate and a piece-wise constant background noise power spectral density estimate. These averaging units are controlled by devices for adapting the length of individual segments to the shape of the high frequency-resolution noisy speech power spectral density estimate and for using the same segmentation in both piecewise constant estimates. A piece-wise constant digital filter transfer function is determined using spectral subtraction-based on the piece-wise constant noisy speech power spectral density estimate and the piece-wise constant background noise power spectral density estimate.

Patent AU-7298587-A (AU)
Title: Guided earth boring tool
Inventor: MCDONALD WILLIAM J
IPC: E21B7/26
Filed: 1987-05-15
Abstract: Long utility holes, for gas lines, electrical conduit, communications conduit and the like, may be bored or pierced horizontally through the earth, particularly under obstacles, such as buildings, streets, highways, rivers, lakes, etc. Such holes may be bored by an underground drilling mole (17) (underground percussion drill) supported on a hollow drill rod (15) and supplied with compressed air through the rod to operate an air hammer which strikes an anvil having an external boring face, preferably constructed to apply an asymmetric boring force. The drill rod is operated by a drill rig on the surface or recessed in special pit for horizontal drilling and provides for addition of sections of pipe or hollow rod as the boring progresses. The asymmetric boring force causes the boring path to curve and, when straight line drilling is needed, the drill rod is rotated to counteract the asymmetric boring force. An alternative boring tool utilizes an expander supported on a solid or hollow drill rod and having a base end supported on and larger in diameter than the rod and tapering longitudinally forward therefrom. It may have a uniform extension protruding a short distance forward. The tool penetrates the earth upon longitudinal movement of the drill rod.
