Publication number: 20230351625Abstract: A method for forming a point cloud corresponding to the topography of an imaged environment involves acquiring an image of the environment with a camera having a WFOV lens mounted on a vehicle; changing the camera pose by an adjustment greater than a threshold; and acquiring another image of the environment with the camera at the changed pose. The images are mapped onto respective surfaces to form respective mapped images, defined by the same nonplanar geometry. One of the mapped images is divided into blocks of pixels. For each block, a depth map is formed by performing a search through the other mapped image to evaluate a disparity in the position of the location of the block of pixels in each of the mapped images. The depth map is converted into a partial point cloud corresponding to the local topography of the environment surrounding the vehicle as it moves through the environment.Type: ApplicationFiled: December 8, 2020Publication date: November 2, 2023Applicant: Connaught Electronics Ltd.Inventors: Ciaran Hughes, Pantelis Ermilios, Matthias Lenk, Sunil Chandra

Patent number: 7729689Abstract: A mobile wireless device, such as a mobile wireless phone, is adapted based on a user's current abstracted contextual situation, where the context of a user is determined using devices enabled with near-field communication technology. Dynamic information of a user of a mobile device, such as the identity of his or her current environment, is determined using near-field communication, such as radio-frequency identification (RFID) tags. Static information regarding the user is also determined, where such static information can include the user's preferences regarding how the mobile device should adapt to certain environments. An abstracted contextual situation of the user is synthesized based on this dynamic and static information. One or more adaptation directives for the mobile device of the user are determined based on the user's abstracted contextual situation.Type: GrantFiled: July 13, 2006Date of Patent: June 1, 2010Assignee: International Business Machines CorporationInventors: Dipanjan Chakraborty, Sudha Krishnamurthy, Sumit Mittal, Sunil Chandra, Pankaj Kankar, Ashish Verma

Patent number: 7669074Abstract: Embodiments herein provide a fault-handling scheme based on forward recovery for cooperative workflow environments. The fault handling scheme relies on the correct placement of transaction scopes and their associated fault and compensation handlers for maintaining correct application semantics, a fault propagation scheme for forwarding faults to a workflow component that has the corresponding fault handler, and a distributed mechanism for collecting data of completed workflow components to facilitate recovering from faults. The fault handling scheme makes use of control flow messages to facilitate compensation of nested transaction scopes (residing in different components). The workflow components are also modified with additional code for aiding with fault propagation and fault recovery.Type: GrantFiled: August 19, 2008Date of Patent: February 23, 2010Assignee: International Business Machines CorporationInventors: Girish B.
