Patent number: 9316735Abstract: A proximity detector may include an array of single photon avalanche diodes (SPADs) and an illumination source. Illumination from the illumination source may be reflected by a target to the array of single photon avalanche diodes. The SPADs may be operable to detect events. A number of events detected may be dependent on a level of illumination incident on the SPADs. The proximity detector may then determine a quality metric and calculate an output when the quality metric is at a predetermined level. A related method may include regulating the quality of the data on which such a proximity detector apparatus calculates its output.Type: GrantFiled: December 9, 2013Date of Patent: April 19, 2016Assignee: STMICROELECTRONICS (RESEARCH & DEVELOPMENT) LIMITEDInventor: David Patrick Baxter

Patent number: 8922682Abstract: An electronic device includes an array of daisy chained image sensors, with each image sensor including a pixel array. A host is coupled to an image sensor at an end of the array and is configured to insert identification codes. The identification codes include embedded data values to thereby indicate specific parts of the image data, and a set of identification codes comprising a first identification code to identify a start of a data stream and a second identification code to identify an end of the data stream.Type: GrantFiled: November 13, 2013Date of Patent: December 30, 2014Assignee: STMicroelectronics (Research & Development) LimitedInventors: Jeffrey Raynor, Patrick Baxter

Patent number: 8120689Abstract: Data is encoded on an image sensor that has a plurality of pixels including one or more bio-sensing pixels and one or more data encoding pixels. The method includes applying a covering material selectively to the data encoding pixels depending on the data to be encoded, the covering material having a detectable difference in opacity relative to having no covering material present. The method includes reading the data encoding pixels, in the presence of light, and decoding data according to a pre-determined scheme depending on the presence of the covering material on the data encoding pixel. As bio-reagents are typically applied after manufacture of the image sensor, the image sensor can have information encoded for electronic detection subsequent to manufacture.Type: GrantFiled: April 29, 2009Date of Patent: February 21, 2012Assignee: STMicroelectronics (Research & Development) LimitedInventors: Jeffrey Raynor, Patrick Baxter
