Patent CA-2155529-A1 (CA)
Title: Imaging apparatus and method for determining range from focus and focus information
Inventor: KRISHNAN ARUN
IPC: G06T1/00
Filed: 1994-02-10
Abstract: A camera having an image plane (AC) which is adjustable with respect to the op-tical axis (OA) is used to determine range information from focus. This imaging ge-ometry eliminates the usual focusing need of image plane movement by replacing the two standard mechanical actions of focusing and panning by panning alone. Range estimation or generation of a focused image of a scene can therefore be performed substantially at the speed of panning.

Patent CA-2162199-A1 (CA)
Title: Acoustic-assisted image processing
Inventor: CHEN HOMER H
IPC: G10L15/00
Filed: 1995-11-06
Abstract: Acoustic-assisted image processing is achieved, in accordance with the invention, by a novel method and apparatus in which an audio signal is sampled at an audio-domain sampling rate; a first viseme sequence is generated at a first rate in response to the sampled audio signal, the first rate corresponding to an audio-domain sampling rate; the first viseme sequence is transformed into a second viseme sequence at second rate using a predetermined set of transformation criteria, the second rate corresponding to a video-domain frame rate; and an image is processed in response to the second viseme sequence. In an illustrative example of the invention, a video image of a face of a human speaker is animated using a three-dimensional wire-frame facial model upon which a surface texture is mapped. The three-dimensional wire-frame facial model is structurally deformed in response to a rate-transformed viseme sequence extracted from a speech signal so that the mouth region of the video image moves in correspondence with the speech. Advantageously, the animation is accomplished in real time, works with any speaker, and has no limitations on vocabulary, nor requires any special action on the part of the speaker.

Title: Microcatheter-less coil delivery device
Inventor: SAMSON GENE
IPC: A61B17/12
Filed: 1995-11-10
Abstract: This invention is a surgical device and a method of using it.  It is a combination in which at least one vasoocclusive device, such as a coil, is placed directly on a core wire.  The vasoocclusive coil (or coils) may be press-fit onto the core wire but are slidably removable using a pusher on the proximal end of the core wire.  The core wire may also function as a guidewire by inclusion of a radiopaque, shapeable tip. This assembly may be used without an infusion or micro-catheter in the cerebral vasculature, although a guiding catheter is often used to direct the assembly to the region of the neck after introduction from an external access point.

Title: Method for measuring speech masking properties
Inventor: SHOHAM YAIR
IPC: G10L19/02
Filed: 1995-12-15
Abstract: A method measures the masking properties of subband components of a signal and determines a noise level vector for the signal. In the preferred embodiment, a signal is separated to yield a set of subband signal components. Bandpass noise components are also generated. For each combination of bandpass noise and subband signal component, the value of the noise-to-signal ratio that meets a specified masking criterion is determined. The values from the combinations are stored. Then, a noise level vector for any other signal can be determined by filtering the signal into a set of components, accessing the stored values and combining the values to yield a measure of the masking properties of the other signal.

Abstract: A contactless interface for transfer of data between a semiconductor music chip and a solid state audio player Data is transferred between the chip and audio player by way of a capacitive interface. The interface comprises a set of conductive plates or electrodes with outer dielectric surfaces on both the music chip and the audio player. Corresponding capacitive plates on the music chip and audio player facilitate data communication by forming a series of capacitors once the music chip is inserted within the audio player so that the capacitive plates of each device are aligned and in close proximity with one another. In accordance with one aspect of the invention a set of four capacitive plates is included on both the music chip and the audio player forming four capacitors. In this arrangement, two plates on each device are utilized to transmit data and two plates are utilized to receive data. The data is serially transferred between devices in a differential scheme utilizing differential receive and drive amplifiers. The differential data transfer minimizes transmission errors and makes the audio player less susceptible to noise. Contacts are also provided as part of the interface for transfer of power, ground and clock signals from the audio player to the music chip.

Abstract: Galvanized steel stock is prepared for the application of a top coating by roughening the surface prior to the application of the top coating. The zinc surface is roughened with the zinc pellets. By using zinc pellets, the treated surface is essentially free of oxidation sites which would later form the basis for corrosion. Both the roughening of the zinc layer of the galvanized steel and the application of the top coating are effected while the zinc coating is still malleable.
