Abstract: A body-mountable device equipped with a light sensor is disclosed. The light sensor includes a photodiode that operates in either a photoconductive mode or a photovoltaic mode depending on whether the photodiode is reverse biased. A group of switches are arranged to selectively couple the photodiode to first and second voltage sources to configure the photodiode to operate in either mode. A controller selects a mode of operation of the photodiode and controls the switches to cause the photodiode to respond to incident light while operating in the selected mode. The controller then obtains a measurement from the photodiode indicative of the intensity of light received during an exposure interval. The light sensor can thus include a single photodiode and yet be used to alternately obtain measurements based on the photoconductive response of the photodiode or based on the photovoltaic response of the photodiode.

Abstract: A method of operating an avalanche photodiode includes providing an avalanche photodiode having a multiplication region capable of amplifying an electric current when subject to an electric field. The multiplication region, in operation, has a first ionization rate for electrons and a second, different, ionization rate for holes. The method also includes applying the electric field to the multiplication region, receiving a current output from the multiplication region, and varying the electric field in time, whereby a portion of the current output is suppressed.

Abstract: Disclosure is related to a sensing module and a Laser device using the sensing module. The sensing module is adapted to a Laser module. The sensing module essentially includes a beam splitter and a photo sensor. This beam splitter is disposed at an optical-axis path of laser beam. The splitter is used to split the laser beam into a transmissive beam and a reflective beam. The photo sensor however is disposed apart from the optical-axis path of the original laser beam. The photo sensor converts the sensed photo signals into electrical signals which are as feedback signals to the laser module.
