Patent number: 10534074Abstract: Disclosed herein are techniques for light beam scanning in a light detection and ranging (LIDAR) system. The LIDAR system includes a beam shaping subsystem configured to generate an illumination pattern elongated in a first direction, and a scanning subsystem configured to direct the elongated illumination pattern towards a plurality of positions along a second direction different from the first direction. The LIDAR system further includes a sensor configured to generate a detection signal in response to detecting light reflected by a target object illuminated by the elongated illumination pattern, and a processor configured to determine a characteristic of the target object based on the detection signal.Type: GrantFiled: August 31, 2016Date of Patent: January 14, 2020Assignee: QUALCOMM IncorporatedInventors: Volodimir Slobodyanyuk, Matthew Grob, John Wyrwas, Karim Arabi, Rajesh Pankaj, Evgeni Gousev, Sajith Balraj

Publication number: 20080013511Abstract: A mobile user terminal 402 accesses a packet data network 450 through one or more of several network access points 404-412. One or more control points 432-440 determines which network access point or points the user terminal is to access. Control may be retained in the current control point, or transferred to another control point, whenever it is convenient. There are preferably several routers, each having an associated home agent 418-420 which determines which foreign agents need to be accessed on behalf of each user terminal. There are several foreign agents 422-430, which forward packets received from a user terminal's home agent to the control point currently controlling communications with the user terminal.Type: ApplicationFiled: July 23, 2007Publication date: January 17, 2008Inventors: Paul Bender, Matthew Grob, Robert Kimball, Gadi Karmi

Publication number: 20070223528Abstract: In a system including a resource which is shared among a number of users, it is difficult to distribute the available capacity of the resources fairly among the users and still maximize resource utilization. Additionally, it is desirable to allow at least some of the control over usage rates to remain with the users, while at the same time avoiding situations where the resource is overloaded. A system and method are disclosed wherein usage rates are selected from among a set of available rates according to a set of persistence vectors.Type: ApplicationFiled: June 1, 2007Publication date: September 27, 2007Applicant: QUALCOMM INCORPORATEDInventors: Gadi Karmi, Matthew Grob, Paul Bender

Publication number: 20070139267Abstract: Embodiments disclosed herein relate to methods and systems for providing improved position-location (e.g., time-of-arrival) measurement and enhanced position location in wireless communication systems. In an embodiment, an access point may replace information (e.g., data) transmission by a “known” transmission (or “reference transmission”) at a predetermined time known to access terminals in the corresponding sectors. The access terminals may use the received reference transmission to perform a position-location measurement, and report back the measured information. The access point may also send a reference transmission on demand, e.g., in response to a request from an access terminal in need for a location-based service.Type: ApplicationFiled: December 20, 2005Publication date: June 21, 2007Inventors: Peter Black, Matthew Grob

Publication number: 20070105584Abstract: A communication system that allows a soft handoff to be completed, even when the communications link between the active base station and the mobile station deteriorates before the mobile station has received the handoff direction message. The mobile station maintains a list of base stations that the mobile station is in communication with, referred to as an “Active Set”. In addition, the mobile station maintains another list of base stations that are proximate to the base stations in the active set. This list is referred to as the “Neighbor Set”. In accordance with the disclosed method and apparatus, the mobile station places a base station in the active set upon including the base station in a pilot strength measurement message (PSMM). The mobile station monitors transmissions from all of the base stations on the active set to receive a handoff direction message (HDM).Type: ApplicationFiled: January 3, 2007Publication date: May 10, 2007Applicant: QUALCOMM INCORPORATEDInventors: Matthew Grob, Roberto Padovani, Paul Bender, Gadi Karmi, Robert Kimball, Greg Hoagland

Publication number: 20070066320Abstract: In a data communication system capable of variable rate transmission, high rate packet data transmission improves utilization of the forward link and decreases the transmission delay. Data transmission on the forward link is time multiplexed and the base station transmits at the highest data rate supported by the forward link at each time slot to one mobile station. The data rate is determined by the largest C/I measurement of the forward link signals as measured at the mobile station. Upon determination of a data packet received in error, the mobile station transmits a NACK message back to the base station. The NACK message results in retransmission of the data packet received in error. The data packets can be transmitted out of sequence by the use of sequence number to identify each data unit within the data packets.Type: ApplicationFiled: September 29, 2006Publication date: March 22, 2007Inventors: Roberto Padovani, Paul Bender, Peter Black, Matthew Grob, Jurg Hinderling, Nagabhushana Sindhushayana, Charles Wheatley

Publication number: 20070042781Abstract: Embodiments disclosed herein relate to methods and systems for server selection during feedback channel impairment in wireless communications. The feedback channel may be provided by a data rate control (DRC) channel, transmitted from an access terminal to an access network relating the selected serving sector (DRC cover) and the desired data rate (DRC rate) for transmission on forward link. During DRC cover erasure (e.g., due to channel impairment), a data source control (DSC) channel may be used as complimentary information to assist the DRC erasure mapping decision at the access network.Type: ApplicationFiled: August 16, 2006Publication date: February 22, 2007Inventors: Mehmet Yavuz, Sarut Vanichpun, Yeliz Tokgoz, Matthew Grob, Peter Black
