    Abstract: A camera including a spherically curved photosensor and a lens system. Effective focal length f of the lens system is within about 20% of the radius of curvature of the photosensor. An image is formed by the lens system at a spherically curved image plane that substantially matches the concave surface of the photosensor. The camera is diffraction-limited with small spot size, allowing small pixels to be used in the photosensor. F/number may be 1.8 or less. The spherically curved image plane formed by the lens system at the photosensor follows f*θ image height law. Chief rays of the lens system are substantially normal to the concave surface of the photosensor. Total axial length of the camera may be 2.0 mm or less. The camera may be implemented in a small package size while still capturing sharp, high-resolution images, making the camera suitable for use in small devices.

    Abstract: Embodiments described include a system comprising a position sensing device (PSD) and a light source. The light source is configured to, by passing one or more light beams through the PSD, cause one or more electrical currents to flow through the PSD. The system further comprises a processor, configured to (i) in response to the electrical currents, ascertain an amount of power that is delivered by the light source, and (ii) in response to the amount of power exceeding a threshold amount of power, inhibit the light source from further operation. Other embodiments are also described.

    Abstract: One embodiment may take the form of a method of operating a computing device to provide presence based functionality. The method may include operating the computing device in a reduced power state and collecting a first set of data from a first sensor. Based on the first set of data, the computing device determines if an object is within a threshold distance of the computing device and, if the object is within the threshold distance, the device activates a secondary sensor to collect a second set of data. Based on the second set of data, the device determines if the object is a person. If the object is a person, the device determines a position of the person relative to the computing device and executes a change of state in the computing device based on the position of the person relative to the computing device. If the object is not a person, the computing device remains in a reduced power state.

    Abstract: An electro-optical device includes a laser light source, which is configured to emit at least one beam of light. A beam steering device is configured to transmit and scan the at least one beam across a target scene. In an array of sensing elements, each sensing element is configured to output a signal indicative of incidence of photons on the sensing element. Light collection optics are configured to image the target scene scanned by the transmitted beam onto the array, wherein the beam steering device scans the at least one beam across the target scene with a spot size and scan resolution that are smaller than a pitch of the sensing elements. Circuitry is coupled to actuate the sensing elements only in a selected region of the array and to sweep the selected region over the array in synchronization with scanning of the at least one beam.
