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

Publication number: 20220080925Abstract: 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: ApplicationFiled: November 22, 2021Publication date: March 17, 2022Inventors: Atul Maharshi, Pablo A.

Publication number: 20220028101Abstract: 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: ApplicationFiled: July 21, 2021Publication date: January 27, 2022Inventors: Atul Maharshi, Pablo A Anigstein, Rajiv Laroia

Patent number: 10159006Abstract: A wireless communications system supports wireless connections between base station sector attachment points and wireless terminals. Individual wireless connections correspond to one of a downlink-macrodiversity mode of operation and a downlink non-macrodiversity mode of operation. A wireless terminal has, for each of its current connections, a base station assigned dedicated control channel for communicating uplink control information reports. The uplink control information reports include downlink signal-to-noise ratio reports based on measured received pilot channel signals. If a connection corresponds to a macrodiversity mode of operation, a reporting format for the SNR report is used which reports (i) an SNR value and (ii) an indication as to whether or not the connection is considered a preferred connection by the wireless terminal. If a connection corresponds to a non-macrodiversity mode of operation, a reporting format for the SNR report is used which reports an SNR value.Type: GrantFiled: July 29, 2015Date of Patent: December 18, 2018Assignee: QUALCOMM IncorporatedInventors: Arnab Das, Pablo Anigstein, Murari Srinivasan, Junyi Li

Patent number: 8995466Abstract: A base station uses a common link layer controller for multiple physical attachment points to facilitate concurrent wireless connections between different sector physical attachment points and a wireless terminal using the same link layer link. A wireless terminal maintains multiple simultaneous wireless connections for the same link layer link. A packet of user data is fragmented into a plurality of grouping of MAC frames, thus a packet portion can be communicated over a connection. A single packet is sometimes communicated with different portions conveyed over different wireless connections. Automatic repeat request, using the common link layer controller, allows for retransmission of a packet portion over a different connection than it was initially transmitted over. A wireless terminal sends connection request messages including lists of link layer identifiers associated with the wireless terminal. A base station responds with an indication of whether logical link state was already present.Type: GrantFiled: December 22, 2005Date of Patent: March 31, 2015Assignee: QUALCOMM IncorporatedInventors: Pablo Anigstein, Murari Srinivasan, Sathyadev Venkata Uppala, Rakesh Champalal Dugad, Arnab Das, Vladimir Parizhsky, Rajiv Laroia
