International Classification:

A61B 18/18

US Classification:

606 17

Abstract:

A catheter tip for delivering laser light energy to create lesions extending to a depth of several millimeters in tissue includes an elongated, flexible housing. A reflector is oriented longitudinally in a channel the housing. A side emitting optical fiber diffuser, extending the length of the reflector, is held at a fixed separation from the reflector. The reflector and the side emitting diffuser are configured and spaced to provide a convergent beam directed through the tissue under treatment. Reflector curvature may be circular or elliptical in cross section, or other selected shape. The diffuser and reflector relative positioning being selected to place the beam focal point (or image) at a predetermined lateral distance from the reflector preferably not closer than the far wall of the tissue under treatment. Temperature probes are provided to monitor the temperature gradient through the tissue thickness. Optionally cooling and/or irrigation fluid are provided. Optionally, the fiber terminates at a retro-reflector.

Appl. No.:

6/478970

Inventors:

Michael M. Levin - Agoura Hills CA

Assignee:

Cybernetic Data Products - Chatsworth CA

International Classification:

H04Q 900
H04J 312

US Classification:

34082552

Abstract:

A packet switching system includes encoding circuitry for generating and intermittently transmitting a plurality of data packets in serial bit stream format. Each data packet consists of a plurality of data words and one or more address words where each such word includes an initial constant value start bit, either a data byte or an address byte, and a steering bit which indicates whether the word is the last to occur address word in the packet. The address byte represents a dimensional identity common to all of the data words in the data packet. The system also includes decoding circuitry including a start bit decoder for sensing the presence of a start bit and a shift register having a number of storage locations equal to the total number of bits in the one or more address bytes, into which bits from the serial bit stream are serially shifted. A register control circuit enables the shift register to receive only the address or data byte bits. A steering bit circuit senses the occurrence of the steering bit and generates an output signal when the word being received is the last to occur address word.

Inventors:

Michael Levin - Miami FL

International Classification:

E04C 141

US Classification:

5230912

Abstract:

A curved block formwork element for use in forming structures such as curved cornices, lintels and window sills. The curved block formwork element comprises a substantially rectangular shaped block having two oppositely disposed side walls and two oppositely disposed end walls creating a hollow cavity inside, wherein a first of the side walls comprises a flat surface and a second of the side walls comprises a curved surface; means for vertically interlocking the block with a plurality of rectangular block formwork elements along a top and bottom surface of the block; and means for horizontally interlocking the blocks.

Appl. No.:

6/575030

Inventors:

Michael M. Levin - Agoura Hills CA

Assignee:

Cybernetic Data Products - Chatsworth CA

International Classification:

H04N 7093
H04N 708

US Classification:

358147

Abstract:

The decoder is capable of locating a data signal within any horizontal line of a video signal, thereby eliminating the necessity for keeping track of the line numbers. The pre-data portion is detected and the data portion is stored in the same register. DC level restoration of the video signal is performed periodically during digitizing. When the decoder is used to receive a data signal in the standard FCC waveform, the clock run in portion, normally used for synchronization in conventional decoders, is detected and the operating rate of the register is adjusted to the rate of the data portion for a number of clock signals equal to the number of data bits to capture the data portion. Once the data has been captured, further signals are prevented from entering the register for approximately one frame to permit the stored data to be retrieved.

International Classification:

H04L 29/06

Abstract:

Aspects of the present application relate to systems and methods for automated web-based filter tuning. The method can include receiving information characterizing a plurality of attributes of a web server and normalizing the received information. The method can include identifying a set of relevant tags to the web server via comparison of the normalized received information to data contained in a tag database, and forming a set of signatures relevant to the web server based at least in part on the set of relevant tags. The method can include receiving an administrator selection of at least some of the set of signatures, enabling the selected at least some of the set of signatures for filtering of received web requests.
