Remote System Status Monitoring And Software Recovery On Wireless Bridges

View page
US Patent:
7248831, Jul 24, 2007
Filed:
Mar 15, 2004
Appl. No.:
10/801971
Inventors:
Metin Ismail Taskin - Mountain View CA, US
David S. Stephenson - San Jose CA, US
David P. Bokaie - Pleasanton CA, US
Lazar Lvovsky - Concord CA, US
Tae Kyoon Jang - San Jose CA, US
Assignee:
Cisco Technology, Inc. - San Jose CA
International Classification:
H04B 3/36
US Classification:
455 8, 455 9, 455420
Abstract:
Disclosed are methods and apparatus for an inside bridge component to monitor the status of an outside unit (ODU) of a wireless bridge and to then handle a faulty ODU and/or faulty cable continuity with the ODU. A mechanism is provided for determining whether the inside component is coupled to a valid ODU prior to the inside component powering up the ODU. Mechanisms are also provided for the inside component to initiate a configuration or software recovery in the ODU. After a valid ODU is powered up, mechanisms are also provided for monitoring the cable continuity between the inside component and the ODU and removing the power from the ODU when the cable continuity is out of specification.

Method And Apparatus For Generating Bipolar Pulses In A Local Area Network

US Patent:
46203109, Oct 28, 1986
Filed:
Mar 11, 1985
Appl. No.:
6/710491
Inventors:
Lazar Lvovsky - Walnut Creek CA
V. Bruce Hunt - Menlo Park CA
Assignee:
Metapath Inc. - Foster City CA
International Classification:
H03L 318
H04B 2549
US Classification:
375 17
Abstract:
A method and apparatus for generating bipolar pulses in a local area network is disclosed comprising a transmitter. In the transmitter there is provided a pair of transistors which are coupled together in a resistor network. A capacitor is provided for coupling the transistors and resistor network to a transmission line. In operation, the output impedance of the transmitter is low when either of the transistors is conducting and high when neither of the transistors is conducting. To generate Alternate Mark Inversion pulses, both transistors are turned on. Thereafter, and in response to a signal corresponding to a logical 1, one of the transistors is turned off and then turned on for generating a positive pulse on the transmission line. Upon the occurrence of a subsequent control signal corresponding to the next logical 1, the other of the transistors is turned off and then on for producing a negative pulse on the transmission line. By alternately turning the transistors on and off upon the occurrence of control signals corresponding to each logical 1, Alternate Mark Inversion pulses are produced on the transmission line.

US Patent:
51596830, Oct 27, 1992
Filed:
Sep 8, 1989
Appl. No.:
7/405041
Inventors:
Lazar Lvovsky - Concord CA
Alexander S. Lushtak - San Francisco CA
Assignee:
Western Digital Corporation - Irvine CA
International Classification:
G05F 314
US Classification:
395500
Abstract:
An automatic monitor sensing graphics controller for use with a computer and a display monitor. The display monitor has a specific capability. The controller, mounted within the computer, comprises a plurality of signal lines, a buffer device connected to both the signal lines and the computer, a connector device connected to both the signal lines and the display monitor, and an automatic monitor sensing unit connected to the signal lines for sensing and determining the capability of the display monitor.
