Patent number: 10397490Abstract: This application discloses an electronic device (e.g., a camera) that operates at two distinct modes and includes a camera lens configured to capture visual data of a field of view, a plurality of light sources, and a light source driver. The light sources are configurable to a plurality of light source subsets to illuminate the field of view. At least two of the light source subsets include distinct light source members and are configured to illuminate different regions of the field of view. The light source driver is configured to drive the light sources with two distinct drive voltages at two distinct modes. In a first mode, the light sources are electrically coupled to each other and driven by a first drive voltage. In the second mode, one of the light source subsets is selected and driven by a second drive voltage that is lower than the first dive voltage.Type: GrantFiled: February 5, 2019Date of Patent: August 27, 2019Assignee: GOOGLE LLCInventors: Arvind Dorai, Anders Nelson, Brian Jonathan Conner

Patent number: 10218916Abstract: This application discloses a camera including a camera lens, a plurality of light sources and bypass circuit. The camera lens is configured to capture visual data of a field of view, and the light sources are configured to illuminate the field of view. The bypass circuit is coupled to the light sources, and configured to group the light sources into a plurality of light source subsets. At least two of the light source subsets include distinct light source members to illuminate different regions of the field of view of the camera. The camera includes a first mode in which the light sources are electrically coupled in series to form a string and driven by a boosted drive voltage, and a second mode in which one of the light source subsets is selected and driven by a regular drive voltage that is lower than the boosted drive voltage.Type: GrantFiled: January 5, 2018Date of Patent: February 26, 2019Assignee: GOOGLE LLCInventors: Arvind Dorai, Anders Nelson, Brian Jonathan Conner

Patent number: 9866760Abstract: This application discloses a lighting emitting diode (LED) illumination system that operates at least in a boost mode and a bypass mode. The LED illumination system includes a plurality of LEDs and bypass elements. Each bypass element is coupled in parallel with one or more LEDs, and configured to bypass them selectively in the bypass mode. A boost converter is configured to drive the LEDs. The boost converter includes a boost controller that is configured to enable the boost mode in response to a boost enable signal. In the boost mode, the boost controller is electrically coupled to control the boost converter to drive the LEDs by a boosted drive voltage, and in the bypass mode, the boost controller is deactivated to allow the boost converter to drive a subset of the LEDs by a regular drive voltage that is substantially lower than the boosted drive voltage.Type: GrantFiled: January 10, 2017Date of Patent: January 9, 2018Assignee: GOOGLE INC.Inventors: Arvind Dorai, Anders Nelson, Brian Jonathan Conner
