Abstract: A multi-source elevation data fusion method including: inputting acquired optical elevation data into a trained optical elevation error prediction model to output an optical elevation error value and an optical elevation error weight map; inputting acquired radar elevation data into a trained radar elevation error prediction model to output a radar elevation error value and a radar elevation error weight map; correcting the optical elevation data based on the optical elevation error value to obtain optical elevation data to be fused; correcting the radar elevation data based on the radar elevation error value to obtain radar elevation data to be fused; performing weighted fusion on the optical elevation data to be fused and the radar elevation data to be fused based on the optical elevation error weight map and the radar elevation error weight map to obtain fused elevation data. This method efficiently enhances the accuracy of fused elevation data.

Abstract: A carrier of a camera module to receive glue for fixing a lens structure thereon comprises a glue dispensing area, the glue dispensing area comprises a bonding area and a groove extending outwards from the bonding area, the groove is directly adjacent to the bonding area to receive glue overflowing from the glue dispensing area. The groove prevents glue dispensed in the bonding area from overflowing towards, or entering, the center of the carrier and improves the production quality of the camera module. The application also discloses a camera module including the above camera carrier.

Abstract: A heat dissipating base for a light-emitting element sufficient to dissipate generated heat without additional means of dissipating includes a first base plate and a second base plate formed on the first base plate. The first base plate includes first sidewalls. The second base plate includes second sidewalls. The first base plate defines a first groove, the first groove passes through one first sidewall to form a first cutout. The second base plate defines a second groove, the second groove passes through one second sidewall to form a second cutout. The first cutout and the second cutout correspond to each other and cooperatively form a heat dissipating opening. The first groove and the second groove correspond to each other and cooperatively form a channel for dissipating heat. A light emitting device having such heat dissipating base is also provided.

Abstract: An apparatus for digital-to-analog conversion and the method thereof is disclosed, wherein the complete scale-tuned levels of more bits may be presented with an output of less bits. The apparatus comprises a timing controller, a scale-tuned circuit and a digital-to-analog converter. The timing controller receives an a-bit grayscale value, and outputs a selection signal and a b-bit control signal, wherein a, b are both positive integers and a>b>=1. The selection signal has two states: if the grayscale value is less than or equal to 2a?2c, wherein c is equal to a?b, the selection signal is in a first state; and if the grayscale value is equal to 2a?2c+n, wherein n is an integer and 0<n<2c, the selection signal has a probability of n/2c to be in a second state, and has a probability of 1?n/2c to be in the first state.
