Publication number: 20240129573Abstract: A processing system receives a user-generated media recording, and metadata associated with the user-generated feedback, from a first device. The user-generated media recording is a recording of the public end-user captured during a live media broadcast using a public-user interface on the first device. The metadata includes information linking the user-generated media recording to the live media broadcast. The system stores the user-generated media recording and the first metadata in one or more storage devices, and transmits a version of the user-generated media recording and at least a portion of the first metadata to a private-user interface on a second device. The private-user interface is configured to receive input from a private end-user selecting the version of the user-generated media recording for broadcast during the same live media broadcast during which the user-generated media recording was created.Type: ApplicationFiled: October 12, 2022Publication date: April 18, 2024Applicant: iHeartMedia Management Services, Inc.Inventors: Albert Curtis Mitchell, Michael Scott Woodruff, Adam Michael Roberts, Steven Douglas Wight, Siu Leung Chan, Jacob Earl Bolton, Stephen William Bain, Qian Chang, Davis Scott Harlan

Patent number: 10522426Abstract: This system and method minimize an effect of haze to signal-to-noise ratio and compensate for haze on the haze map. A first mask with a first aperture is disposed along the path of the light beam between a light source and a collector. A first actuator moves the first mask along a tangential direction. A second mask with a second aperture is disposed along the path of the light beam between the first mask and the collector. A second actuator moves the second mask along a radial direction perpendicular to the tangential direction. The first mask and the second mask are independently movable along the tangential direction and the radial direction using the first actuator and the second actuator.Type: GrantFiled: February 8, 2019Date of Patent: December 31, 2019Assignee: KLA-Tencor CorporationInventors: Hongxing Yuan, Dimitry Pokras, William VanHoomissen, Douglas Chan

Patent number: 10003476Abstract: In one embodiment, a source top-of-rack (ToR) switch may identify multiple destination ToR switches from a group of ToR switches to send data traffic to. The source ToR switch may be connected to the group of ToR switches via a base network. The system may determine whether each destination ToR switch is suitable for receiving data transmission via a point-to-multipoint wireless flyway. The two or more destination ToR switches that are determined to be suitable may be considered flyway candidate ToR switches. The system may establish the point-to-multipoint wireless flyway between the source ToR switch and the flyway candidate ToR switches. The system may then transmit the data traffic from the source ToR switch to each of the flyway candidate ToR switches via the point-to-multipoint wireless flyway.Type: GrantFiled: April 7, 2017Date of Patent: June 19, 2018Assignee: CISCO TECHNOLOGY, INC.Inventors: Douglas Chan, David R.

Patent number: 9661357Abstract: A user device may send a request for a data file to an access point. The user device may then receive, from the access point, data indicating that a segment of the data file has been previously cached in a local cache at the access point.

Patent number: 9344856Abstract: The trustworthiness of vehicle-to-vehicle (V2V) messages received from one or more associated vehicles in the vicinity of a subject vehicle is determined autonomously by a false signal detection system of the subject vehicle. Physical evidence relating to the associated vehicles is collected, and a statistical model is used to perform an analysis of the collected data. A V2V message is received by the system from a first one of the associated vehicles and a trustworthiness level of the message is determined in accordance with a correlation between the received V2V message and the result of the analyzed physical data relating to the first associated vehicle. The correlation may be a comparison of data contained in the received V2V message relative to a result of a stochastic analysis of the physical data. The received V2V message may be any V2V safety message including Emergency Electronic Brake Light (EEBL) messages.Type: GrantFiled: January 14, 2014Date of Patent: May 17, 2016Assignee: CISCO TECHNOLOGY, INC.Inventors: Tao Zhang, Douglas Chan, Helder Antunes

Patent number: 9332046Abstract: An edge server communicates with a client in a local network. The client displays a remote desktop image representative of a virtual desk image generated by a virtual desktop server (VDS). The edge server receives from the VDS a desktop image to be displayed on the remote desktop. The desktop image includes an incomplete window in which graphic media, such as video, is to be displayed. The edge server determines communication link conditions in the local network and a corresponding transmit data rate at which to transmit data to the client device and a suitable encoding rate at which the graphic media is encoded. The edge server downloads the graphic media from the content server, merges the downloaded graphic media into the incomplete area to produce a completed desktop image, and transmits the completed desktop image at the determined transmit data rate for display on the remote desktop.Type: GrantFiled: October 17, 2013Date of Patent: May 3, 2016Assignee: Cisco Technology, Inc.Inventors: Douglas Chan, Jiang Zhu, Hao Hu

Patent number: 9125214Abstract: Wider bandwidth transmissions are dynamically enabled in a wireless networking environment. During a transmit opportunity time interval for a wireless network device, a transmission is sent in a primary channel in a frequency band in which the primary channel and a secondary channel may be used simultaneously to send a wider bandwidth transmission. Activity is monitored in the secondary channel. A determination is made as to whether the secondary channel is free based on the monitoring. When it is determined that the secondary channel is free, the wider bandwidth transmission is sent in the primary and secondary channels.Type: GrantFiled: September 4, 2012Date of Patent: September 1, 2015Assignee: Cisco Technology, Inc.Inventors: Brian D. Hart, Douglas Chan, David Kloper

Patent number: 9094223Abstract: Techniques are provided for delivering data to a wireless client device in a wireless network via a plurality of access points as the wireless client device roams from one access point to another. A wireless client device receives data via a first wireless access point in the wireless network. An impending roam of a wireless client device is detected. A set of one or more candidate wireless access points other than the first wireless access point is determined to which the wireless client device may potentially roam. The one or more wireless access points in the set are assigned to a multicast group, and the traffic is sent to the multicast group. A message containing a synchronized context enables a new wireless access point to send data to the wireless client device from a point where the first wireless access point stopped sending data to the wireless client device.Type: GrantFiled: October 27, 2014Date of Patent: July 28, 2015Assignee: Cisco Technology, Inc.Inventors: Hui Liu, Douglas Chan, Tak Ming Pang
