Patent number: 9773037Abstract: Systems and methods for processing user requests for updating data in a CRM system. When a user requests to update data in the CRM system, it is determined if the requested data change involves a DCR-controlled field. If yes, the requested data change may be routed to the MDM system for validation first and the data change may not be used to update the CRM until the validation is successful. If the requested data change does not involve any DCR-controlled field, it may update the CRM immediately.Type: GrantFiled: May 1, 2015Date of Patent: September 26, 2017Assignee: VEEVA SYSTEMS INC.Inventors: Uri Reich, Pengfei Liu, Arno Sosna, Povilas Petkevicius, Edward Gee, David Wright, Jay H Hartley, Sadhana Jain, Abhay Pimprikar

Patent number: 6877692Abstract: The invention provides a propulsion system based on “thuniform” movement of a foil member to achieve desired directional movement of a vehicle such as an unmanned submarine type of vessel. A pair of foil members are mounted to the vehicle body for reciprocating oscillating movement towards and away from each other, creating forward movement due to the compression of a fluid medium between the foil members and the expulsion of the compressed fluid rearwardly of the foil members. Each foil member is mounted to a pivot shaft for limited rotational movement with respect to the vehicle body. Damping means are connected between each pivot shaft and its associated foil member so that during operation of the propulsion system damping torque will offset hydrodynamic loads imposed on the foil members by the fluid medium. The damping means will in turn control the pitch angle of the foil members during operation, meaning that a thrust is generated for rigid foil members when moving at zero forward speed.Type: GrantFiled: March 5, 2004Date of Patent: April 12, 2005Assignee: National Research Council of CanadaInventor: Pengfei Liu
