Patent number: 10547793Abstract: A camera unit and method of control are described. The camera unit has a camera flash sub-unit configurable to emit flash light having an adjustable characteristic. A camera sensor sub-unit generates raw color data when exposed to light for processing into a digital image. The camera unit also includes a camera controller for coordinating operation of the camera flash sub-unit and the camera sensor sub-unit. The camera controller monitors one or more ambient light characteristics in a vicinity of the camera unit. Prior to receiving a command instructing the camera unit to generate the digital image, the camera controller repeatedly configures the camera flash sub-unit based on the monitored ambient light characteristics to adjust the characteristics of the emitted flash light. Once the camera controller receives the command, the camera sensor sub-unit is instructed to expose an image sensor using the pre-adjusted camera flash light to increase illumination.Type: GrantFiled: May 4, 2017Date of Patent: January 28, 2020Assignee: BlackBerry LimitedInventors: Qian Wang, Yun Seok Choi, Graham Charles Townsend, Sui Tong Tang

Patent number: 10223363Abstract: The controlling of access to a file system entity based on location of the requestor and operation expiry data of the file system entity. Operation expiry data and location data are associated with a file system entity (e.g., a file, a directory, a partition, or a disk) such that the file system entity and the operation expiry data and the location data are moved or copied atomically together. Upon receiving a request to perform an operation on the file system entity, the system identifies a location status of the requestor. The system then identifies expiry data that corresponds to the location status, and that is associated with the requested operation. The system then uses the identified expiry data to determine whether or not the requested file operation is to be permitted.Type: GrantFiled: October 30, 2014Date of Patent: March 5, 2019Assignee: Microsoft Technology Licensing, LLCInventors: Graham Charles Plumb, Warren Leslie Keyes
