Patent number: 11196282Abstract: An emergency lighting assembly is provided having a housing with one or more adjustable lamp assemblies for aiming the light at selected areas. The lamp assembly is mounted in the housing by a ball and socket arrangement. The lamp assembly has a substantially spherical shape with a front section made of a heat conducting material and a rear section made of a plastic material. The front section has an opening on a front side having a lens and a base spaced from the front side supporting the light source. The light source in one embodiment is an LED which is coupled to the front section to conduct heat from the LED away from the LED and the housing. The rear section has an opening in the rear side that receives a fixed stop member to limit pivoting movement of the lamp assembly with respect to the housing. The rear section also includes a projection oriented to contact the stop member to limit rotation of the lamp assembly with respect to the housing.Type: GrantFiled: January 28, 2020Date of Patent: December 7, 2021Assignee: Hubbell IncorporatedInventors: Steven Holscher, Han Lei

Patent number: 9491386Abstract: A reset level in a pixel cell is boosted by switching ON a reset transistor of the pixel cell to charge the floating diffusion to a first reset level during a reset operation. A select transistor is switched from OFF to ON during the floating diffusion reset operation to discharge an output terminal of an amplifier transistor. The reset transistor is switched OFF after the output terminal of the amplifier transistor has been discharged in response to the switching ON of the select transistor. The output terminal of the amplifier transistor charges to a static level after being discharged. The floating diffusion coupled to the input terminal of the amplifier transistor follows the output terminal of the amplifier transistor across an amplifier capacitance coupled between the input terminal and the output terminal of the amplifier transistor to boost the reset level of the floating diffusion.Type: GrantFiled: December 3, 2014Date of Patent: November 8, 2016Assignee: OmniVision Technologies, Inc.Inventors: Qingfei Chen, Duli Mao, Han Lei Lock, Qingwei Shan

Patent number: 9380234Abstract: A reduced random telegraph signal (RTS)-noise CMOS image sensor includes a pixel and a correlated double sampling (CDS) circuit electrically connected to the pixel. The CDS circuit is characterized by a CDS period that includes a reference sample period and an image data sample period. The image sensor also includes a bitline, a bitline connection switch between the pixel and a readout circuit connected to the pixel, and a bitline switch controller. The bitline transmits a transfer gate signal as a bitline signal having a non-zero value during a first time period entirely between the reference sample period and the image data sample period. The bitline switch controller is electrically connected to and configured to control the bitline connection switch such that the bitline connection switch is closed during the entire CDS period except for a single continuous open period that includes the first time period.Type: GrantFiled: May 1, 2015Date of Patent: June 28, 2016Assignee: OmniVision Technologies, Inc.Inventors: Qingfei Chen, Qingwei Shan, Han Lei Lock

Patent number: 8865335Abstract: An electrochemical storage cell is disclosed that comprises a cathode sheet, an anode sheet, and a separator sheet between the cathode and anode sheets. A metal foil current collector extends from a longitudinal edge of the cathode sheet. A further metal foil current collector extends from a longitudinal edge of the anode sheet. The anode sheet, cathode sheet, and separator sheet are wound in a flattened coil shape to produce a core in which the metal foil current collector of the cathode sheet extends beyond the separator sheet at one end of the core and the metal current collector of the anode sheet extends beyond the separator sheet at an opposite end of the core. Overlying layers of the metal foil current collector of the cathode sheet are compressed together and placed in electrical communication with a positive terminal of the cell while overlying layers of the metal foil current collector of the anode sheet are compressed together and placed in electrical communication a negative terminal of the cell.Type: GrantFiled: December 22, 2008Date of Patent: October 21, 2014Assignee: BYD Co.
