Patent number: 9918613Abstract: An observation object is imaged under irradiation with oxygen saturation level measurement light to obtain a first image signal, and the observation object is imaged under irradiation with white light to obtain a second image signal. A normal light image is produced from the second image signal. An oxygen saturation level is calculated from the first and second image signals. The calculated oxygen saturation level is imaged in an oxygen saturation image. By superimposing the normal light image on the oxygen saturation image, an emphasized oxygen saturation image is produced. In the emphasized oxygen saturation image, an abnormal area in which a calculation result of the oxygen saturation level is likely to be abnormal is emphasized by its brightness. The produced emphasized oxygen saturation image is displayed on a display device.Type: GrantFiled: February 4, 2014Date of Patent: March 20, 2018Assignee: FUJIFILM CorporationInventors: Takaaki Saito, Hiroshi Yamaguchi, Takayuki Iida

Patent number: 9916507Abstract: A network device determines an exposure time associated with an image sensor coupled to a spacecraft for capturing an image of a target object orbiting the Earth. The network device computes a maximum relative angular velocity associated with the target object based on the exposure time and a dimension of a pixel of the image sensor. The network device identifies a first pointing direction of the image sensor for initiating a search for the target object. The network device generates a first angular velocity probability distribution map for the target object and divides the first angular velocity probability distribution map into a first set of angular velocity regions (AVRs). The network device selects a first AVR from the first set of AVRs for scanning by the image sensor and generates a search schedule that includes a first entry for informing the spacecraft to scan the first AVR.Type: GrantFiled: November 13, 2015Date of Patent: March 13, 2018Assignee: RKF Engineering Solutions LLCInventors: Jeffrey Freedman, Erik Halvorson

Patent number: 9892188Abstract: Innovations for category-prefixed data batching (“CPDB”) of entropy-coded data or other payload data for coded media data, as well as innovations for corresponding recovery of the entropy-coded data (or other payload data) formatted with CPDB. The CPDB can be used in conjunction with coding/decoding for video content, image content, audio content or another type of content. For example, after receiving coded media data in multiple categories from encoding units, a formatting tool formats payload data with CPDB, generating a batch prefix for a batch of the CPDB-formatted payload data. The batch prefix includes a category identifier and a data quantity indicator. The formatting tool outputs the CPDB-formatted payload data to a bitstream. At the decoder side, a formatting tool receives the CPDB-formatted payload data in a bitstream, recovers the payload data from the CPDB-formatted payload data, and outputs the payload data (e.g., to decoding units).Type: GrantFiled: November 8, 2012Date of Patent: February 13, 2018Assignee: Microsoft Technology Licensing, LLCInventors: Gary J. Sullivan, Leon Bottou, Sandeep Kanumuri, Yongjun Wu
