Patent number: 10102242Abstract: A system, method, and computer program product are provided for handling bulk initial downloads of databases to mobile devices. Rather than straining the resources of a mobile device to recreate the database locally, a server can construct the database to the mobile device's requirements at the server by impersonating the mobile device. The server can then send the database, compressed and over an encrypted session, to the mobile device. The mobile device can then decrypt and uncompress the pages received, and then encrypt them using a local key for secure storage on a local storage device.Type: GrantFiled: October 18, 2011Date of Patent: October 16, 2018Assignee: SYBASE, INC.Inventors: Evan Ireland, Brett Donahue, Guo-ping Zhang, Xiong He

Patent number: 9797493Abstract: An actuator for adjusting a seat includes a motor, a gear-box, and an output member. The gear-box includes a casing accommodating a two stage gear train connecting the motor to the output member. The gear train has a first and second transmission mechanisms. The first transmission mechanism includes a worm on a shaft of the motor, and a worm wheel meshed with the worm. The second transmission mechanism is a movable teeth gear transmission mechanism and has an eccentric wheel that rotates with the worm wheel, an internally toothed ring gear fixed to the casing, a fluted disc with radial grooves formed in its outer periphery, and rollers mounted in the radial grooves. The eccentric wheel drives the rollers to mesh with the ring gear to rotate the fluted disc, to drive the output member.Type: GrantFiled: May 20, 2015Date of Patent: October 24, 2017Assignee: JOHNSON ELECTRIC S.A.Inventors: Jing Ning Ta, Xue Qian Xu, Guo Ping Zhang

Patent number: 9336291Abstract: A system, method, and computer program product are provided for executing a notification query derived from a download cursor for a business object to identify an updated subscription. The download cursor is run against the updated subscription to generate result rows. The result rows are sent to a client device in an import message. Additional systems, methods, and computer program products are provided for guaranteeing at-least-once delivery of a message.Type: GrantFiled: June 10, 2010Date of Patent: May 10, 2016Assignee: SYBASE, INC.Inventors: Evan Ireland, David Clegg, Michael Ho, Hemal Pandya, Guo-ping Zhang

Patent number: 9109677Abstract: The planetary gear train includes a first sun gear driven by the motor, a first ring gear, a first carrier, and a plurality of first planetary gears arranged at one side of the first carrier and meshing with the first sun gear and the first ring gear. The first sun gear, first planetary gears and first ring gear are helical gears so that meshing surface is increased. Helical teeth formed on an inner surface of the first ring gear mesh with the helical teeth of the first planetary gears. Therefore, the operation is stable and the noise is low. The planetary gears are made of plastic to further decrease the noise. The first ring gear is made by sintered powder metallurgy.Type: GrantFiled: April 17, 2013Date of Patent: August 18, 2015Assignee: JOHNSON ELECTRIC S.A.Inventors: Yue Wang, Xing Ju Yi, Guo Ping Zhang, Xiao Hui Wang, Hong Yu Ding, Jing Ning Ta, Dennis Francis Gorosin

Patent number: 8321392Abstract: A system, method, and computer program product are provided for invoking an operation to change a current data row of a table in a local database. As a result, a pending change data row is inserted in the table, distinguished by a primary key comprising a common key value and a pending change indicator. The pending change is then submitted for synchronization.Type: GrantFiled: June 10, 2010Date of Patent: November 27, 2012Assignee: Sybase, Inc.Inventors: Evan Ireland, David Clegg, Michael Ho, Hemal Pandya, Guo-ping Zhang

Patent number: 6907090Abstract: Methods and corresponding apparatus to recover data from a signal comprising groups of pulses generated in response to analog waveforms are described. Data recovery in accordance with the invention is based on parameters characterizing the groups of pulses. These parameters are the basis for mapping the groups of pulses to information symbols which collectively constitute the data to be recovered.Type: GrantFiled: March 13, 2001Date of Patent: June 14, 2005Assignee: The National University of SingaporeInventor: Guo Ping Zhang

Patent number: 4737713Abstract: An apparatus and method for processing a first electrical signal having a frequency interval I containing information, and increasing the signal-to-noise ratio thereof utilizes a mixer for shifting the frequencies of the first signal in the interval I to an interval I.sub.s. A plurality of filters, coupled in parallel, to the mixer pass, respectively, only frequencies in subintervals of I.sub.s, which are mutually disjoint. A second embodiment utilizes a plurality of mixers which shift, respectively, mutually disjoint subintervals of I such that their left end points are substantially equal. A plurality of filters, coupled, respectively, to the mixers, pass, respectively, only those frequencies in the shifted subintervals. Preferably, the frequency intervals passed by the filters in both embodiments are equal in bandwidth, and have no gaps therebetween.Type: GrantFiled: November 26, 1986Date of Patent: April 12, 1988Assignee: Fonar CorporationInventors: Gordon T.
