An illumination module can comprise a circuit board, a semiconductor-based light source
mounted to the circuit board, an encasing mounted to the circuit board, and one or more …

A spherical background object that is substantially centered around a head of a user and
has a predetermined radius is set in a virtual space. Icons are dispersedly disposed in the …

(57) ABSTRACT A relative position based eye tracking system includes a light source to
illuminate a portion of the eye and an optical sensor to capture a sequence of samples of the …

(57) ABSTRACT A device for treating living tissue with a magnetic field. The device includes
one or more coil applicators; and a generator configured to drive a stimulation coil that is …

A depth camera assembly (DCA) determines distances between the DCA and objects in a
local area within a field of view of the DCA. The DCA projects a series of sinusoidal patterns …

(57) ABSTRACT A method of tracking movement of an eye of a user includes directing a
light beam at the eye. The eye may reflect a portion of the light beam. The method further …
