Abstract:
In one embodiment, a computer system stores speech data for a plurality of speakers, where the speech data includes a plurality of feature vectors and, for each feature vector, an associated sub-phonetic class. The computer system then builds, based on the speech data, an artificial neural network (ANN) for modeling speech of a target speaker in the plurality of speakers, where the ANN is configured to discriminate between instances of sub-phonetic classes uttered by the target speaker and instances of sub-phonetic classes uttered by other speakers in the plurality of speakers.
Abstract:
A p-type polysilicon resistor formed in the inter-level dielectric layer contains an implanted diode. A positive voltage applied to the diode modulates the depletion region of the diode and changes the absolute resistance of the p-type polysilicon resistor. This modulation occurs not only horizontally, but also vertically. The fact that the tunable resistor is a p-type polysilicon resistor means that this structure can easily be integrated into the process since polysilicon is used as a gate material for basic CMOS processing.
Abstract:
An improved girt for building construction that provides structural stability and significantly reduces thermal bridging in facade and cladding wall assemblies. The girt is made of a reinforced, fire-resistant, thermoset resin that does not readily burn. The girt completely eliminates metal-to-metal connection points between internal building structures such as columns or posts and external wall panels, resulting in substantially reduced thermal bridging and U values.
Abstract:
Embodiments of the present invention improve content manipulation systems and methods using speech recognition. In one embodiment, the present invention includes a method comprising configuring a recognizer to recognize utterances in the presence of a background audio signal having particular audio characteristics. A composite signal comprising a first audio signal and a spoken utterance of a user is received by the recognizer, where the first audio signal comprises the particular audio characteristics used to configure the recognizer so that the recognizer is desensitized to the first audio signal. The spoke utterance is recognized in the presence of the first audio signal when the spoken utterance is one of the predetermined utterances. An operation is performed on the first audio signal.
Abstract:
A plate heat exchanger includes a set of plates and gaskets. Each one of the set gaskets is disposed between two adjacent plates of the set of plates. A gasket of the set of gaskets includes a base material, a fluorocarbon coating disposed on the base material; and an interface layer disposed between the base material and the fluorocarbon coating. The interface layer includes a material gradient transitioning from the base material to the fluorocarbon coating. The fluorocarbon coating is chemically bound to the base material.
Abstract:
The present invention provides a diffusion resistor that is formed in the substrate. A diffusion region is formed within the substrate that contains first and second contact regions extending downward from the surface of the substrate. Third and fourth contacts are also located within the diffusion region between the first and second contacts and define a conduction channel therebetween. This contact also extends downward from the surface of the substrate. These contacts are connected to metal layers. The first and second contacts form the two ends of the diffusion resistor; the third and fourth contacts connect to N+p− diodes such that application of a voltage to these contacts forms respective depletion regions within the diffusion region. The depletion regions change in size depending on the voltage applied to their respective contact, thereby changing the resistance of the depletion resistor.

The third contact forms a Schottky diode such that application of a voltage to this contact forms a depletion region within the diffusion region. The depletion region changes in size depending on the voltage applied to the third contact to change the resistance of the depletion resistor.
