Publication number: 20220366348Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for determining true utilization based on productive behaviors of operators in a digital environment. One of the methods includes automatically determining productivity for each of multiple users of an organization. Timing data for a user is received that indicates available work time for the user. Interaction data is received for the user for interactions by the user during the available work time for the user. Productivity rules for an organization of the user are received that define productivity of interactions by users of the organization. Productivity of interactions of the user is determined based on the interaction data and the productivity rules. True utilization for the user is determined based on the productivity of the interactions and the timing data. Action data is generated based on the determined true utilization action is taken based on the action data.Type: ApplicationFiled: May 13, 2021Publication date: November 17, 2022Inventors: Alec DeFilippo, Samuel Lessin, Ben Vishny, Andrew Staub, Evan Lloyd

Patent number: 11499941Abstract: A flexible eddy current probe for non-destructive testing of a metallic object may include one or more plus-point coils and a flexible printed circuit having first and second parallel sides, third and fourth parallel sides, and a number of adjacent strips. The strips have first and second ends that are contiguous with the first and second parallel sides, respectively. Each of the strips may contain a pair of coils oriented along the length of the strip, a first coil being proximate to the first end and a second coil being proximate to the second end, and each of the coils is configured to excite an eddy current in the metal object or to sense an eddy current. Each of the strips may also be independently flexible from one another. The eddy current sensor array is configured to be scanned over the metal object.Type: GrantFiled: December 11, 2019Date of Patent: November 15, 2022Assignee: Zetec, Inc.Inventors: Steve Timm, Evan Lloyd, Tom O'Dell, Bill Ziegenhagen, Evans Nguyen

Publication number: 20220318319Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for determining focus events. One of the methods includes determining time spent by a user. A sequence of events occurring in multiple software services being accessed by a user is tracked. The sequence of events includes one or more events from each case of a group of cases handled by the user. Using information extracted from one or more interactions of the user with at least one service, focus events are determined that identify which case in the group of cases is being worked on by the user at various points in time, each focus event having a focus event duration. Using the extracted information, each focus event of the focus events is assigned to a particular case. A total period of time spent by the user on the particular case is determined based on a sum of focus events durations for the focus events assigned to the particular case.Type: ApplicationFiled: March 31, 2021Publication date: October 6, 2022Inventors: Ben Vishny, Evan Lloyd, Samuel Lessin

Patent number: 10695322Abstract: New antimicrobials targeting L,D-transpeptidases, non-classical cysteine peptidases, have been developed and their unique chemical structures identified. Carbapenems and penems of the present invention are unique among ?-lactams as they acylate and inhibit L,D-transpeptidases, which likely results in their superior antimicrobial potency. These new antimicrobial agents can be used alone, or in combination with other classic antimicrobial agents that target D,D transpeptidases, when treating bacterial infections.Type: GrantFiled: January 26, 2017Date of Patent: June 30, 2020Assignees: The Johns Hopkins University, Rutgers, The State University of New JerseyInventors: Gyanu Lamichhane, Craig A.
