Patent number: 8614632Abstract: This device, by its organization and operation, processes sound, usually music. It provides output voltages, for driving lights, which is proportionally representative of input sound levels. Range of sound perception of the human ear exceeds the range of perception of the human eye. It is necessary to adjust the sound level by compression and Automatic Gain Control, particularly by compression, to accommodate the eyes. A requirement to have the output drive voltage drive the lights is to have a linear response to the compressed audio signal. This requirement is met with an output drive circuit which, has a linear response to the compressed signal. This is achieved with a linear firing circuit when providing output voltage using SCR's or Triacs. In a straightforward variation of the output circuit to improve the power factor, the linear response is maintained by modulating the output with transistors instead of using SCR's or Triacs.Type: GrantFiled: November 2, 2010Date of Patent: December 24, 2013Inventors: Kenneth A Wells, Victor W Hatch

Patent number: 8248467Abstract: In one aspect, the present disclosure relates to a method of detecting information transmitted by a light source in a complementary metal-oxide-semiconductor (CMOS) image sensor by detecting a frequency of light pulses produced by the light source. In some embodiments, the method includes capturing on the CMOS image sensor with a rolling shutter an image in which different portions of the CMOS image sensor are exposed at different points in time; detecting visible distortions that include alternating stripes in the image; measuring a width of the alternating stripes present in the image; and selecting a symbol based on the width of the alternating stripes present in the image to recover information encoded in the frequency of light pulses produced by the light source captured in the image.Type: GrantFiled: March 16, 2012Date of Patent: August 21, 2012Assignee: ByteLight, Inc.Inventors: Aaron Ganick, Daniel Ryan

Patent number: 8228182Abstract: A self-testing notification appliance includes a notification emitter, a verification circuit, and a controller. The notification emitter is operable to output light or light and sound based on a control signal. The verification circuit includes a notification sensor to detect the light or light and sound and generate a verification signal. The controller sends the control signal to the notification emitter and receives information based on the verification signal from the verification circuit. The self-testing notification appliance may be part of a network including a fire control panel and a plurality of additional self-testing notification appliances. The self-testing notification appliances may be assigned addresses on the network.Type: GrantFiled: June 11, 2009Date of Patent: July 24, 2012Assignee: SimplexGrinnell LPInventors: Todd F. Orsini, Anthony J. Capowski, Michael A. Furtado

Patent number: 8085163Abstract: A system that varies the brilliance of light bulbs in accordance with modulated audio signals. The audio signals are first compressed and then passed through a comparator. The comparator has two inputs, one of which is the aforesaid compressed audio signals. The other input is a control input which receives a second voltage in the form of a series of impulses. The compressed audio signals pass through the comparator if and when their voltage is higher than that of said second voltage.Type: GrantFiled: September 20, 2007Date of Patent: December 27, 2011Inventors: Kenneth A. Wells, Victor W. Hatch

Patent number: 8072342Abstract: An overcurrent protection circuit connected between a voltage input and a voltage output of an electronic device to protect against excessive current is disclosed. The overcurrent protection circuit includes first to fifth resistors, a relay comprising a coil and a normally closed switch, a pnp transistor, and a break-over element. When a current between the voltage input and the voltage output is greater or equal to a rated current of the electronic device, the npn transistor is turned on, while the coil is powered on to control the switch to be opened, therefore the voltage output cannot output voltage, which can protect against excessive current damaging the electronic device.Type: GrantFiled: September 16, 2009Date of Patent: December 6, 2011Assignees: Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventor: Yong-Zhao Huang

Patent number: 8004420Abstract: A security lighting system and method are intended to dispel and/or affect unwanted humans or animals by providing lighting that varies with a suitable switching frequency, such as between 5 and 70 Hz. The lighting of a light source of the system may be varied by a control unit as to intensity, color, pattern etc., with a preferred switching frequency being between about 15 and 20 Hz for humans. A proximity detector may be provided to activate the system when an unwanted presence is detected. Such varying lighting causes feelings of physical and psychological discomfort, which have found to be effective in chasing away animals and dispelling or disorienting humans.Type: GrantFiled: June 1, 2006Date of Patent: August 23, 2011Assignee: Koninklijke Philips Electronics N.V.Inventors: Wilhelmus Frederik Laurens Maria Hoeben, Ronald Edwin Lavooi, Petrus Johannes Mathijs Van Der Burgt
