A navigation device having a small navigation sensor pixel array capable of ultra high speed imaging is proposed. A first image and a second image of a plurality of images are selected according to a predetermined difference between the corresponding acquisition times of the first image and the second image. The first image and the second image are compared to determine an amount of overlap between the first image and the second image. The predetermined difference is adjusted for subsequent image comparisons according to the amount of overlap between the first image and the second image.

Reduction of silicon die size for a navigational sensor using ultra high frame rate acquisition

Disclosed are various embodiments of temperature-compensated relaxation oscillator circuits that may be fabricated using conventional CMOS manufacturing techniques. The relaxation oscillator circuits described herein exhibit superior low temperature coefficient performance characteristics, and do not require the use of expensive off-chip high precision resistors to effect temperature compensation. Positive and negative temperature coefficient resistors arranged in a resistor array offset one another to provide temperature compensation in the relaxation oscillator circuit.

Temperature compensation circuit and method

An electronic flash, imaging device and method for producing a flash of light having a wavelength spectrum in the visible wavelength range and the infrared wavelength range uses a fluorescent material to convert at least some of the original light emitted from one or more light sources of the electronic flash to longer wavelength light to produce the flash of light. The light sources may be configured to generate light having a peak wavelength in an ultraviolet-and-visible wavelength range. The fluorescent material may include any combination of red, green, blue and yellow phosphors.

Electronic flash, imaging device and method for producing a flash of light having a wavelength spectrum in the visible range and the infrared range using a fluorescent material

A device and method for providing illuminating light utilizes quantum dots to convert at least some of the original light emitted from a light source of the device to longer wavelength light to change the color characteristics of the illuminating light. The quantum dots may be included in the light source, a light panel and/or an optional interface medium of the device.

Device and method for providing illuminating light using quantum dots

A light emitting device in which a primary light generator, such as a light emitting diode (LED) or laser diode, is operable to emit a primary light that is received by a body of wavelength converting material. A portion of the primary light is absorbed by the body of wavelength converting material and is emitted as secondary light. The wavelength converting material contains phosphor nano-particles and larger phosphor particles. The phosphor nano-particles prevent transmission of primary light while the larger phosphor particles provide efficient light conversion.

Light source with wavelength converting material

A device and method for emitting output light utilizes both quantum dots and non-quantum fluorescent material to convert at least some of the original light emitted from a light source of the device to longer wavelength light to change the color characteristics of the output light. The device can be used to produce broad-spectrum color light, such as white light.
