Patent number: 11622270Abstract: Physical-layer authentication based on the channel response over a wireless medium are described. In a first authentication scheme, a count is kept of how many significant multipath taps remain empty or occupied from one channel estimate to the next for authentication purposes. In a second authentication scheme, which does not require an alternative means of initial authentication, the presence of a multipath component based on a reported position of a transmitter and the side knowledge of planar reflectors in the environment may be leveraged for authentication purposes.Type: GrantFiled: May 20, 2021Date of Patent: April 4, 2023Assignee: The Government of the United States of America, as represented by the Secretary of the NavyInventors: Scott Frederick Lord, John David-Dickson Roth, Murali Tummala, John Colin McEachen

Publication number: 20220276168Abstract: An apparatus (100) for optically characterizing a textile sample (106) comprises a presentation subsystem (102) comprising a viewing window (108). A radiation subsystem (114) comprises a radiation source (120) for directing a first, ultraviolet radiation (122) and a second, visible radiation (123) toward the sample (106), and causing the sample (106) to produce a fluorescent radiation (124) and a reflected radiation (125). A sensing subsystem (126) comprises an imager (130) for capturing the fluorescent radiation (124) and the reflected radiation (125) in an array of pixels (408). A control subsystem (132) comprises a processor (136) for controlling the presentation subsystem (102), the radiation subsystem (114), and the sensing subsystem (126), and for creating a fluorescent and reflected radiation image (400) containing both spectral information and spatial information in regard to the fluorescent radiation (124) and the reflected radiation (125).Type: ApplicationFiled: November 6, 2019Publication date: September 1, 2022Applicant: Uster Technologies AGInventors: Peyman Dehkordi, Kent A.

Publication number: 20200265539Abstract: An off-duty scheduling system for police officers automatically generates a list of qualified available officers. Filtering eliminates, from the candidate pool, officers lacking requisite training or credentials, officers who have reached or exceeded off-duty work limits, and inactive officers. Multi-level sorting arranges the candidate pool in order of priority based upon specified criteria, such as, time from last off-duty assignment and seniority. Officers are invited to perform the job, until the job is fully staffed. Start and end of job performance are tracked and reported, with payments made automatically upon completion.Type: ApplicationFiled: February 20, 2019Publication date: August 20, 2020Applicant: Off Duty Force, LLCInventors: Rockwell Allen Morris, David Dickson, John Dean

Patent number: 10748184Abstract: Systems, methods, apparatuses and computer-readable media for receiving data associated with a plurality of users, such as a group of employees receiving benefits from an employer. The plurality of users may have a primary insurance provider. Insurance information associated with one or more covered services or claims submitted may be received from the primary insurance provider and matched to the plurality of users to identify a portion (or any) of the users who have submitted a claim or received covered services. In some arrangements, a determination may be made as to whether the identified users have supplemental coverage. If so, a notification may be transmitted to the user indicating eligibility for coverage.Type: GrantFiled: June 11, 2014Date of Patent: August 18, 2020Assignee: Allstate Insurance CompanyInventors: K Pearl Harrison, David Dickson
