Abstract: A system and method receive a first beam pattern from an optical source that includes optical beams transmitted towards a target. The system and method measure a first vertical angle between at least two of the optical beams along a first axis relative to the FMCW LIDAR system. The system and method calculate a second beam pattern based on the first vertical angle and a pivot point. The second beam pattern produces a second vertical angle between the two optical beams. The system and method adjust one or more components from a first position that forms the first beam pattern to a second position that forms the second beam pattern for transmission towards the target. The system and method receive one or more return optical beams from the target, based on the second beam pattern, to produce a plurality of points to form the point cloud.

Abstract: Aspects of the present disclosure provide light detection and ranging (LIDAR) systems and methods for changing or adjusting field of view (FOV) during operation. Changing the FOV may include transmitting an optical beam toward a target, and forming the FOV using the optical beam via a first rotating reflector and a second rotating reflector. The first rotating reflector may include a galvo mirror in control of the vertical FOV, and the second rotating reflector may include a rotating polygon mirror in control of and providing for the horizontal FOV. The FOV may be adjusted in the vertical direction by actuating the first rotating reflector along a vertical direction using a first actuator. The first actuator may determine the actuation based on an orientation of the LIDAR system (e.g., a difference between an initial orientation measured after installation and a baseline orientation referencing a horizontal orientation).

Abstract: A light detection and ranging (LIDAR) system that includes an optical processing system to transmit an optical beam and receive a return signal responsive to transmission of the optical beam. The system also includes a 1D scanning mirror to reflect the optical beam from the optical processing system to a plurality of multifaceted mirrors. The system also includes a first multifaceted mirror and a second multifaceted mirror coupled to the first multifaceted mirror in a stacked configuration. The 1D scanning mirror is controllable to direct the optical beam to the first multifaceted mirror to generate a first scan pattern and to the second multifaceted mirror to generate a second scan pattern.

Abstract: A system and method include receiving a first beam pattern from an optical source that comprises a plurality of optical beams transmitted towards a target causing different spaces to form between each optical beam. The system and method include measuring a vertical angle between at least two of the optical beams along a first axis and calculating a second beam pattern based on the vertical angle and a pivot point that causes the optical beams to be transmitted towards the target with substantially uniform spacing. The system and method include adjusting, at the pivot point, one or more components to form the second beam pattern to adjust the plurality of different spaces to the substantially uniform spacing for transmission towards the target. The system and method include receiving return optical beams from the target to produce a plurality of points to form the point cloud.

Abstract: Embodiments of the invention include a microphone assembly having a microphone soldered on a bottom side of a bottom ported microphone flex circuit carrier, and a rigid coupler soldered on the top side of the carrier, opposite to the microphone. The coupler is inserted into and sealed to a microphone boot made out of a soft material. The top of the boot may be sealed to an electronic audio device into which the assembly is integrated. Acoustic openings through the housing, boot, coupler and carrier allow acoustic signals to reach the microphone. However, the seals between the housing, boot, coupler, carrier and microphone provide sound isolation, as well as a moisture and dust seal between the ambient and the inside of the electronic device. Such seals may include rings, grooves, threads, O-rings between the boot and coupler; or a reinforcing ring around the soft material of the boot.

Abstract: A portable electronic device having an outer case having a substantially planar face in which a microphone associated acoustic port is formed. The device also has a micro-electro-mechanical system (MEMS) microphone positioned within the outer case, the MEMS microphone having a diaphragm facing the microphone associated acoustic port. An acoustic mesh is positioned between the front face of the outer case and the diaphragm, the acoustic mesh having a non-linear acoustic resistance so as to minimize an effect of an incoming air burst on the diaphragm. Other embodiments are also described and claimed.
