The (LED or-and Laser) light source for bulb or light device such as garden light that has at least one of or more than one optics-lens, and light device has one top cover having shape of flat or ½ ball, ⅔ ball, sphere, dome shape for top cover. Foe laser light source incorporate with flat top protective lens and laser film or grating film to enlarge or created plurality of image, lighted patterns. For LED light source can has project assembly which is a built-in or add-on or assembled inside of said light device. Further can incorporated flexible bendable arms to change position, direction, orientation of (LED or-and Laser) light beam. The said Light device also can offer near-by and far-away illumination, or-and lighted image, pattern projection with desired light effects by rotating optic-lens or LED(s). It also can get desired effects while LED(s) controlled by IC or circuitry making LED(s) for color changing or on-off on desired time, duration, cycles. The light device further can have more than one function selected from USB charger, power failure, RF remote control, Infra-red controller, blue-tooth, wifi, internet, App software, motion sensor and wireless with multiple-way communication. Also, light device may have rechargeable circuit, batteries or rechargeable battery, USB ports for the (LED or-and Laser)-bulb be charged or supply other device current.

An electronic apparatus includes an authenticator configured to identify registered finger information that coincides with detected finger information by matching the detected finger information with the plurality of registered finger information in a predetermined order, an executor configured to execute a function corresponding to the registered finger information identified by the authenticator, a user identifier configured to identify the actual user among the plurality of registered users by acquiring user identification information representing the actual user or by performing a determination process configured to determine the actual user, and a controller configured to change the predetermined order according to the actual user identified by the user identifier.

A computational pixel imaging device that includes an array of pixel integrated circuits for event-based detection and imaging. Each pixel may include a digital counter that accumulates a digital number, which indicates whether a change is detected by the pixel. The counter may count in one direction for a portion of an exposure and count in an opposite direction for another portion of the exposure. The imaging device may be configured to collect and transmit key frames at a lower rate, and collect and transmit delta or event frames at a higher rate. The key frames may include a full image of a scene, captured by the pixel array. The delta frames may include sparse data, captured by pixels that have detected meaningful changes in received light intensity. High speed, low transmission bandwidth motion image video can be reconstructed using the key frames and the delta frames.

In some examples, a computing device can include a processor resource and a non-transitory memory resource storing machine-readable instructions stored thereon that, when executed, cause the processor resource to: instruct an imaging device to capture an input image, determine image properties of the input image, activate a portion of a plurality of light sources based on a physical location of the plurality of light sources and the determined image properties of the input image, and instruct the imaging device to capture an output image when the portion of the plurality of light sources are activated.
