Patent number: 12135418Abstract: A wiper is controlled to sweep a surface area, e.g., a portion of a windshield, in front of a camera, e.g., a camera mounted inside a vehicle. An image captured from the camera after the wiper completes, e.g., immediately completes, the sweep of the surface area in front of the camera is used in generating a depth map. In some embodiments a first wiper is controlled to clear a surface area in front of a first camera while a second wiper is controlled to clear a surface area in front of second camera at the same time, and the first and second cameras are synchronized to initiate image capture at the same time, capturing images through recently cleared area, and the captured images are used to generate a depth map. A vehicle control operation, e.g., a direction, braking or speed control operation is performed based on the depth map.Type: GrantFiled: November 22, 2021Date of Patent: November 5, 2024Assignee: Deere & CompanyInventors: Atul Maharshi, Pablo A Anigstein, Rajiv Laroia

Patent number: 12067740Abstract: Methods and apparatus for processing images captured by cameras for use in stereo depth determinations are described and/or for using depth information generated by processing such images is described. Images are captured using a reference camera and at least one additional camera. Filtering is implemented as part of a patch matching process to reduce the risk of erroneous matches, e.g., due to image blur in one image but not another. The filtering may be, and sometimes is, implemented on a patch basis. A candidate patch is generated by filtering a portion of an image captured by a camera, e.g., a second camera by performing a sharpening or blurring operation to a portion of the image to generate a candidate patch. The amount of blurring or sharpening that is applied to generate the candidate patch depends, in some embodiments, on the relative difference between the candidate patch and the reference patch.Type: GrantFiled: July 21, 2021Date of Patent: August 20, 2024Assignee: Deere & CompanyInventors: Atul Maharshi, Pablo A Anigstein, Rajiv Laroia

Patent number: 11537027Abstract: Methods and apparatus for using a controllable filter, e.g., an liquid crystal panel, in front of a camera are described. The filter is controlled based on the luminosity of object in a scene being captured by the camera to reduce or eliminate luminosity related image defects such as flaring, blooming or ghosting. Multiple cameras and filters can be used to capture multiple images as part of a depth determination processes where pixel values captured by cameras at different locations are matched to determine the depth, e.g., distance from the camera or camera system to object in the environment. Pixel values are normalized in some embodiments based on the amount of filtering applied to a sensor region and sensor exposure time. The filtering allows for regional sensor exposure control at an individual camera even though the overall exposure time of the pixel sensors may be and often will be the same.Type: GrantFiled: January 19, 2020Date of Patent: December 27, 2022Assignee: Blue River Technology Inc.Inventors: Atul Maharshi, Pablo A Anigstein, Rajiv Laroia

Patent number: 9014069Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in connection with selection of a communication mode based on traffic type information. In one example, a network entity (e.g., a WiFi router, Picocell, Fentocell, an eNB, etc.) is equipped to obtain traffic type information for content to be transmitted by a network entity, determine a communication mode to use for transmission of the content based on the traffic type information, and transmit the content using the determined communication mode. In an aspect, the traffic type information may indicate that the content is a best effort traffic type, a latency sensitive traffic type, or no traffic type is available.Type: GrantFiled: November 7, 2012Date of Patent: April 21, 2015Assignee: QUALCOMM IncorporatedInventors: Shailesh Patil, Hua Wang, Juergen Cezanne, Pablo A.

Patent number: 8812676Abstract: A method, an apparatus, and a computer program product are provided in which signals are received on each of a plurality of resources and an energy of each of the signals of a set of the plurality of resources is determined. In addition, a resource is determined based on a probability for each of the resources in a subset of the set. The probability for selecting a resource with a lower determined energy is less than one and greater than the probability for selecting a resource with a higher determined energy. Furthermore, a signal is transmitted on the selected resource.Type: GrantFiled: September 3, 2010Date of Patent: August 19, 2014Assignee: QUALCOMM IncorporatedInventors: Shailesh Patil, Thomas Richardson, Xinzhou Wu, Junyi Li, Saurabh Tavildar, Pablo A.

Publication number: 20110085611Abstract: A multi-mode base station includes a transmit standby mode and an active mode. Transmit standby mode of base station operation is a low power/low interference level of operation as compared to active mode. In transmit standby mode at least some of the synchronization signaling such as pilot tone signaling is reduced in power level and/or rate with respect to the active mode. In transmit standby mode, the base station has no active state registered wireless terminals being serviced but may have some sleep state registered wireless terminals being serviced. Mode transitions from active to transmit standby may be in response to: a detected period of inactivity, scheduling information, base station mode change signals, and/or detected wireless terminal state transition. Mode transitions from transmit standby to active may be in response to: scheduling information, access signals, wake-up signals, hand-off signals, wireless terminal state change signals, and/or base station mode change signals.Type: ApplicationFiled: July 9, 2010Publication date: April 14, 2011Applicant: QUALCOMM INCORPORATEDInventors: Rajiv Laroia, Pablo A.

Publication number: 20100015983Abstract: Methods and apparatus for indicating parameter change points with respect to multiple connections (wireless links) by transmitting a single message, e.g., over one of the connections, is described. A base station corresponding to at least one connection, considers the approximate timing relationship between the connections, selects one of the connections, selects an intended parameter switching point for that connection, determines a symbol time offset from the selected switching point such that the other intended switching points of other wireless links can be unambiguously interpreted by the wireless terminal from information indicating the offset with respect to the selected link, and communicates information indicating the offset and the wireless link to which said offset applies. A wireless terminal receives the information, identifies a time referenced with respect the timing structure of the identified wireless link and then determines individual parameter switching points for the other wireless links.Type: ApplicationFiled: June 19, 2009Publication date: January 21, 2010Applicant: QUALCOMM IncorporatedInventor: Pablo A.
