Filed:

Oct 16, 2000

Appl. No.:

09/688590

Inventors:

John D. Cashman - Boxborough MA

International Classification:

G06F 1500

US Classification:

712277, 712209, 712 36

Abstract:

A programmable data communications device is provided to process multiple streams of data according to multiple protocols. The device is equipped with a co-processor including multiple, programmable processors allowing data to be operated on by multiple protocols. The programmable processors within the co-processor include extended instruction sets including instructions providing the operations of zero stuffing, CRC computation, partial compare, conditional move, and trie traversal. These instructions allow the processor(s) of the co-processor to more efficiently execute programs implementing data communications protocols. Since each processor is programmable, protocols standards which change may be accommodated. A network device equipped with the co-processor can handle multiple simultaneous streams of data and can implement multiple protocols on each data stream. The protocols can execute within the co-processor either independently of each other, or in conjunction with each other.

International Classification:

G06F 1300

US Classification:

709200

Abstract:

A modem for processing telephone calls includes a line interface for coupling the modem to a telephone line and a computer interface for coupling the modem to a host computer. A processor in the modem between the line interface and the computer interface receives signals running between the telephone line and the host computer. Both the signal processing session and the control processing session required to process the signals are implemented on the single processor.

International Classification:

H04L 1216

US Classification:

370259

Abstract:

An apparatus for processing telephone calls is connected between a primary rate ISDN (PRI) telephone line and a host computer. Telephone call data is transferred between the host computer and remote analog, basic rate ISDN (BRI) and/or PRI remote sites. The apparatus includes a digital signal processor that can run multiple signal processing sessions simultaneously and a control processor that can run multiple control processing sessions simultaneously. The apparatus can therefore process multiple telephone calls of one or more types simultaneously.

International Classification:

A61B 17/70
A61B 90/00

Abstract:

A device configured to provide a faster and more accurate measurement of depths of holes for placement of bone screws and fastener for bone implant fixation procedures. The device includes a combination of a bone probe for physical examination of a hole drilled in a bone and a depth gauge member for determining a depth of the hole and providing digital measurement of the depth via a display on the instrument and/or via a wireless exchange of measurement data to a remote computing device, such as a tablet or smartphone.
