Abstract: A laser projector comprising at least one source for laser beams, a mirror mechanism adapted to reflect laser beams is disclosed, for providing a plurality of projected frames wherein each of the plurality of projected frames is generated by laser beams scanning an image both in the horizontal direction and in the vertical direction, wherein at least two frames from among the plurality of projected frames are generated by using laser beams each of which having at least one different projecting parameter than the other frame, and wherein the projecting parameter is a member selected from a group consisting of: a frame's starting point for the beam's scanning, a frame's starting scanning time, picture information and horizontal and/or vertical cycle times.

Abstract: A MEMS apparatus is provided for scanning an optical beam which comprises: a. at least one mirror operative to perform am oscillation motion to a pre-defined rotation angle around a mirror rotation axis; b. a sound sensing means; and c. a conversion means operative to convert sound vibrations detected by the sound sensing means into one or more electrical signals, and wherein the sound sensing means is located at the vicinity of the at least one mirror whereby the movement of the at least one mirror sensed by the sound sensing means and converted by the conversion means into the one or more electrical signals characterizing the oscillating motion of the at least one mirror.

Abstract: A method for monitoring movement of at least one moving mirror in a MEMS device comprising one or more moving mirrors, and wherein the monitoring is based upon capacitance changes over time in the MEMS device. The method comprises the steps of: if the at least one moving mirror is an in-plain mirror, then: a. providing DC voltage to the MEMS device in addition to a driving voltage required for the movement of that at least one moving mirror; b. measuring current proportional to capacitance changes associated with the movement of the at least one moving mirror; and c. monitoring the movement of the at least one moving mirror based on the measured current. If the at least one moving mirror is a staggered mirror, then: d. measuring a current associated with the movement of the at least one moving mirror; e. identifying a plurality of ripples associated with capacitance changes in the MEMS device over time, in the measured current; and f.

Abstract: An efficient vehicle remote control system for controlling vehicle sub-systems, devices and accessories. The system includes a connector device (110) connected to the vehicle central computer through a vehicle bus such as CAN bus. The system further includes remote control device (109, 111, 112) communicating with the connector device, through which various accessories installed in the vehicle are operatively controlled.
