Publication number: 20240106747Abstract: In association with a virtual area, a first network connection is established with a first network node present in the virtual area and a second network connection is established with a second network node present in the virtual area. Based on stream routing instructions, a stream router is created between the first network node and the second network node. The stream router includes a directed graph of processing elements operable to receive network data, process the received network data, and output the processed network data. On the first network connection, an input data stream derived from output data generated by the first network node is received in association with the virtual area. The input data stream is processed through the stream router to produce an output data stream. On the second network connection, the output data stream is sent to the second network node.Type: ApplicationFiled: December 7, 2023Publication date: March 28, 2024Applicant: Sococo, LLCInventors: Robert J. Butler, Joseph Altmaier, David Van Wie

Patent number: 11936499Abstract: Apparatus and methods of managing a virtual area based on communicant capabilities are described. The communicant capabilities are updated based on rules in response to events in the virtual area. An action by one communicant can affect the capabilities of another communicant. Communicant capabilities can be stored in respective server-side proxies and the virtual area can be managed without transmitting any of the capabilities to the communicants' client network nodes. Capability-based permissions checks can be performed against communicant capabilities with wildcarded attribute fields.Type: GrantFiled: July 6, 2021Date of Patent: March 19, 2024Assignee: Sococo, Inc.Inventors: Robert J. Butler, Matthew Leacock, David Van Wie, Paul J. Brody, F. Randall Farmer

Publication number: 20160191188Abstract: A local interconnection carries one or more local interconnect optical channels between optical nodes at a site. The optical nodes include reconfigurable optical add-drop multiplexers (ROADMs). The local interconnect optical channels are switched by the ROADMs in the optical nodes for transmission over the local interconnection. In addition, modules within an optical node are operable to communicate using an LI optical channel that is switched over a local interconnection by a ROADM of the optical node.Type: ApplicationFiled: December 31, 2014Publication date: June 30, 2016Applicant: ALCATEL-LUCENT USA INC.Inventor: David J.

Publication number: 20160182152Abstract: A method includes determining a first subset of a set of optical channels, wherein each channel of the first subset has a bit error ratio (BER) greater than each channel of a remaining subset of the channels. A second subset of the set of optical channels is determined, wherein each channel of the second subset has a BER less than each channel of the remaining subset of the channels. Input power level (P) and/or dispersion compensation (D) of one or more of the channels of the first subset is adjusted, thereby reducing an aggregate BER of the first subset. P and/or D of one or more of the channels of the second subset is adjusted, thereby increasing an aggregate BER of the second subset. A reduction of an aggregate BER of the set of optical channels results from the adjusting of the first and second subsets.Type: ApplicationFiled: December 22, 2014Publication date: June 23, 2016Inventors: Lev Sofman, David J.

Patent number: 8336432Abstract: A safety system for a rotary saw or other dangerous machine tools features a flesh-sensing circuit (14, 19), located on a safety guard (16) surrounding a dangerous machine part, which generates an electronic signal to trigger emergency stopping of the machine before the operator can contact the dangerous machine part. The stopping means preferably employs DC injection, winding current direction reversal and/or electromagnetic motor braking, in the event of detection of operator contact with the safety guarding device. The system is adapted to be used both with newly-manufactured machine tools and by retrofitting onto previously-manufactured machine tools, by in-the-field modifications.Type: GrantFiled: September 24, 2011Date of Patent: December 25, 2012Inventor: David J Butler

Patent number: 7221869Abstract: A system for identifying transmission rates of an optical signal transmitted in an optical communication network includes a signal converter for converting a sample of the optical signal to an electrical signal. A frequency analyzer analyzes the electrical signal to determine energy levels of the signal at predetermined frequencies. The detected energy levels are stored in a first memory device. A second memory device stores known energy levels at predetermined frequencies for a plurality of known optical transmission standards. A comparator receives the detected energy levels stored in the first memory device and compares this information to the known transmission standards stored in the second memory device in order to identify the data transmission standard of the optical signal.Type: GrantFiled: June 19, 2002Date of Patent: May 22, 2007Assignee: Alcatel LucentInventors: Robert Burford, David J.
