  • Publication number: 20150077004
    Abstract: A bleeder circuit includes a first resistor, a thermistor, a transistor, a second resistor, and a diode section. The first resistor biases the transistor into an always-on status. The second resistor prevents current from flowing through the thermistor responsive to a voltage at the positive terminal being greater than a minimum forward voltage of a load. The thermistor increases in electrical resistance, limiting the current flowing therethrough and preventing damage to the load responsive to the load short-circuiting.

  • Patent number: 8901850
    Abstract: An adaptive anti-glare light system including a sensor, a color selection engine, a controller, and a plurality of light sources each configured to emit a source light. The sensor transmits a source color signal designating a reflected light characterized by a detected color and a discomfort glare rating. The color selection engine determines a dominant wavelength of the detected color, and a combination of the light sources that the controller may operate to emit a combined wavelength that matches the dominant wavelength of the detected color. A method of adapting light as a countermeasure to glare comprises receiving the detected color, determining a subset of the plurality of light sources that may be combined to form an adapted light that matches the detected color, and operating the light sources with a white light to emit the adapted light at or above a threshold discomfort glare level.
