Abstract: An image projection device, such as a pico projector or LCD projector, includes image projection circuitry configured to generate a light beam having a power. The image projection circuitry projects the light beam onto and focuses the light beam on a projection surface located an imaging distance from the image projection circuitry. A time-of-flight sensor is configured to sense the imaging distance between the image projection circuitry and the projection surface and to generate an imaging distance signal indicating the sensed imaging distance. Control circuitry is coupled to the image projection circuitry and to the time-of-flight sensor and is configured to adjust the power and the focus of the light beam based upon the imaging distance signal.

Abstract: A semiconductor packaging unit mounts onto a board by solder joints. The unit includes, disposed along one axis, a semiconductor component having on a rear face protruding electrical connection lugs designed to be soldered onto the board and an external cage surrounding the component and having a rear edge designed to be soldered onto the board and a front part through which a front part of the component passes. The component and the cage are designed to axially slide with respect to one another in such a manner as to be brought into their soldering position with respect to the board and having complementary holding parts coming into contact and designed to hold them with respect to one another when they are axially removed from the soldering position and to free them with respect to one another when they are at the soldering position.
