US Patent:

6470390, Oct 22, 2002

Filed:

Jun 29, 1999

Appl. No.:

09/342864

Inventors:

William E Westfield - Atherton CA

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

G06F 1300

US Classification:

709227, 370438, 370439, 703 23

Abstract:

A method and apparatus establishes a connection for a communication session between two remote devices, then negotiates an additional connection. One of the connections is used to communicate data, not commands, allowing that connection to be more efficient because each remote device does not have to scan it for commands in the information it receives.

Appl. No.:

09/880236

Inventors:

William Chops Westfield - Atherton CA

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H04N 714

US Classification:

348 1412, 348 1413, 348 1408

Abstract:

Systems and methods for providing digital video teleconferencing over a network that allows a user to view the event in a manner more closely approximating live viewing are provided, while not requiring excessive use of bandwidth. Low resolution and high resolution of a videoconference event are obtained, preferably by using two cameras at the event. A whole eye view is sent to clients at low resolution. A user at the client can select one or more areas of interest to him (âattention windowsâ). High resolution data from the attention window(s) selected by each user is sent to the respective client. The client displays the whole eye view and the attention window data.

Appl. No.:

09/803424

Inventors:

William Westfield - Atherton CA, US

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H04Q007/20

US Classification:

4554564, 4554042, 455457

Abstract:

In an IP-based cellular wireless communication system, systems and methods for spatially controlling cellular phone usage are provided. Entry of a cellular phone device into an area of restricted phone access (“quiet zone”) is detected and an IP message identifying the phone sent to a central facility. In one embodiment, an IP message is sent to the phone causing it to change behavior, for example turning off the volume on the ringer. Alternatively, the central facility can process an incoming call for a phone that is determined to be in a quiet zone to reduce intrusion in the quiet zone; for example, it can send the call to a phone mailbox or give the caller a busy signal.

Appl. No.:

12/231158

Inventors:

William Westfield - Atherton CA, US

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H04W 24/00

US Classification:

4554564, 4554042, 455457, 455433, 455411, 4554561

Abstract:

In one embodiment, a device in an IP-based cellular wireless communication system includes a monitoring arrangement and a sender arrangement. The monitoring arrangement arranged to detect a location of a cellular phone device with respect to an area of restricted access. The location of the cellular phone device with respect to the area of restricted access is detected in part by determining when a preset period of time has elapsed. The sender is arranged to send a first message including information associated with the cellular phone device when the location of the cellular phone device with respect to the area of restricted access is detected. A method for operating the device is also disclosed.

Appl. No.:

10/150273

Inventors:

William Westfield - Atherton CA, US

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

G06F 15/173
G06F 15/16

US Classification:

709230, 709223, 709224

Abstract:

Systems and methods for providing a highly useful partial implementation of a network protocol using limited processing and memory resources are provided. This allows network nodes embedded in simple devices such as light switches, thermostats, etc. to be reached using conventional open standard network protocols such as TCP/IP. A representative application is remotely adjusting a house thermostat by accessing a web page.
