Patent number: 10716086Abstract: A device receives reference data from reference receivers associated with base stations, and synchronizes the reference data to a reference time to generate synchronized reference data for the reference receivers. The device processes the synchronized reference data to determine location error information associated with one or more of the reference receivers, and receives information indicating that a user device, located at an observed location, connects to a particular base station of the base stations. The device determines a location correction for the observed location, or an actual location of the user device, based on particular location error information for a particular reference receiver, of the reference receivers, associated with the particular base station, and causes information identifying the location correction or information identifying the actual location of the user device to be provided to the user device.Type: GrantFiled: August 31, 2017Date of Patent: July 14, 2020Assignee: Verizon Patent and Licensing Inc.Inventors: Christopher N. Del Regno, Jean M. McManus, Matthew W. Turlington, Mohammed M. Rahman

Patent number: 10592935Abstract: An event recording is received. The event is associated with an event entity and occurs over an event duration at an event location. A tag is received responsive to user interaction with a communication device. The tag is associated with at least one of the particular entity associated with the event entity, a particular time period associated with the event duration, and a particular location associated with the event location. Additional information associated with the event recording is received, and the tag is matched with at least a portion of the event recording based on at least one of the particular entity, the particular time period, and the particular location associated with the received tag. The portion of the event recording matching the received tag is presented for review along with the received additional information associated with the event recording.Type: GrantFiled: September 30, 2014Date of Patent: March 17, 2020Assignee: AT&T Intellectual Property I, L.P.Inventors: Luis Albisu, Joseph Bentfield

Patent number: 10439799Abstract: Indirect fire protocol according to several embodiments of the present invention can include the initial step establishing a grid and locating a forward observer (FO) and a firing unit (FU) in the grid. The FO can estimate the bearing and range to a High Value Target (HVT) within the grid, and can homomorphically encrypting said HVT estimated position data. FO can then transmit the encrypted HVT estimated position data over cloud network architecture to a Fire Direction Center (FDC), using the FDC's Keypublic. The FDC can outsource the calculation of an absolute position of said HVT in said grid to non-secure internet cloud architecture, but with encrypted HVT estimation data and the FO position data in the grid (which the FDC knows). Once calculated, the HVT encrypted absolute position data can be decrypted, and then transmitted from FDC to a FU, using the FU's Keypublic.Type: GrantFiled: August 17, 2017Date of Patent: October 8, 2019Assignee: United States of America as represented by Secretary of the NavyInventors: Mamadou H.

Patent number: 10241844Abstract: First and second circuits in an integrated circuit that generate local hot spots are activated at different times in order to reduce heat generation within each of the first and second circuits. The first and second circuits in the integrated circuit have the same circuit architecture. The first circuit processes data during a first time period, and heat generation is reduced in the second circuit during the first time period. A data path of the data is then switched from the first circuit to the second circuit. The second circuit then processes the data during a second time period after the first time period, and heat generation is reduced in the first circuit during the second time period. The data path of the data is then switched from the second circuit back to the first circuit. The first circuit then processes the data again.Type: GrantFiled: May 11, 2017Date of Patent: March 26, 2019Assignee: Intel CorporationInventors: David Mendel, Rajiv Kane
