Publication number: 20240078571Abstract: Methods and systems for analyzing vehicle operation data associated with a temporary or periodic usage of a vehicle by a driver. In aspects, the vehicle operation data may be analyzed to assess a performance of the driver during operation of the vehicle. Based on the performance of the driver, the driver may qualify for a reward.Type: ApplicationFiled: October 31, 2023Publication date: March 7, 2024Inventors: Kerry Lynne Cote, Nicholas R.

Patent number: 10091013Abstract: A local router stores a content distribution map that specifies a plurality of permitted multicast groups. The local router receives communications from user devices on an access-network side of the local router. Those received communications identify multicast groups for which user devices wish to receive data. The local router ascertains if those identified multicast groups are permitted multicast groups specified by the stored content distribution map. For multicast groups ascertained to be permitted multicast groups, the local router sends communications across a network-side interface requesting membership in those multicast groups. The local router may then receive data for those multicast groups and forward that data to user devices. For multicast groups identified in user device communications ascertained not to be permitted multicast groups, the local router sends no communications across the network-side interface requesting membership.Type: GrantFiled: May 24, 2017Date of Patent: October 2, 2018Assignee: Comcast Cable Communications, LLCInventor: Brian E. Field

Patent number: 9769028Abstract: Methods and systems are disclosed for receiving data from each of a plurality of components in a network, the components being arranged as a plurality of multicast trees, the data from each of the components indicating a structure of a portion of the network and at least one attribute associated with the respective component. The disclosure further provides for determining, based on the data, a structure of at least some of the multicast trees, receiving search criteria, and determining which of the multicast trees meet the search criteria.Type: GrantFiled: September 9, 2015Date of Patent: September 19, 2017Assignee: Comcast Cable Communications, LLCInventors: Brian E.

Patent number: 9398263Abstract: A first device communicates with subscriber devices in an access network. A communication is sent from a subscriber device to the first device requesting that the subscriber device be permitted to join a multicast group associated with data for a desired content. After determining that the subscriber device is authorized to receive that content, the first device sends one or more multicast signaling communications to a second device. The multicast signaling communications instruct the second device to join the requested multicast group and provide an identifier associated with that multicast group. After joining the multicast group and receiving content data packets of that group, the second device encapsulates those received packets in frames according to an access network media access control (MAC) protocol and forwards the MAC frames to the subscriber device. The MAC frames include the identifier provided to the second device by the first device.Type: GrantFiled: July 24, 2012Date of Patent: July 19, 2016Assignee: Comcast Cable Communications, LLCInventor: Brian E.

Patent number: 9130830Abstract: A method for detecting errors on an audio/video (A/V) data stream in a data service network includes providing multicast components operably coupled to each other via respective links for transmitting the A/V data stream to a user and for defining at least one multicast tree. The method further includes generating a state information signal indicative of a number of errors on the A/V data stream for at least one of the links and at least one of the plurality of multicast components. The method further includes determining the cumulative number of errors on the A/V data stream that are indicative of the number of errors for the at least one of the links and the at least one of the plurality of multicast components in the multicast tree in response to the state information signal.Type: GrantFiled: August 6, 2012Date of Patent: September 8, 2015Assignee: Comcast Cable Holdings, LLCInventor: Brian E.
