    Abstract: A packaged microchip has a base, a die with a mounting surface, and an electrically inactive interposer between the base and the die. The interposer has a first side with at least one recess that extends no more than part-way through the interposer from the first side. Accordingly, the recess defines a top portion (of the first side) with a top area. The die mounting surface, which is coupled with the interposer, correspondingly has a die area. The top area of the interposer preferably is less than the die area.

    Abstract: A MEMS device has a substrate with a structure surface and an opposing exterior surface, microstructure formed on the structure surface of the substrate, and a cap coupled with the substrate to form a hermetically sealed interior chamber containing the microstructure. The substrate forms a trench extending from, and being open to, the opposing exterior surface to produce a sensor region and a second region. Specifically, the second region is radially outward of the sensor region. The MEMS device also has a spring integrally formed at least in part within the trench to mechanically connect the sensor region and the second region, and other structure integral with the substrate. The spring or the other structure at least in part hermetically seal the interior chamber.

    Abstract: A two-axis microelectromechanical systems (MEMS) gyroscope having four proof masses disposed in respective quadrants of a plane is described. The quad proof mass gyroscope may comprise an inner coupler passing between a first and a third proof mass and between a second and a fourth proof mass, and coupling the four proof masses with one another. The quad proof mass gyroscope may further comprising a first outer coupler coupling the first and the second proof masses and a second outer coupler coupling the third and the fourth proof masses. The outer couplers may have masses configured to balance the center of masses of the four proof masses, and may have elastic constants matching the elastic constant of the inner coupler. The quad gyroscope may further comprise a plurality of sense capacitors configured to sense angular rates.

    Abstract: This disclosure describes techniques for operating a lidar device. The techniques include emitting light resulting in a plurality of non-parallel laser beam waves; directing the plurality of non-parallel laser beam waves towards a laser beam scanner; reflecting the non-parallel plurality of beam waves by the laser beam scanner towards a collimator device; collimating, with the collimator device, the plurality of non-parallel laser beam waves reflected by the laser beam scanner into a corresponding plurality of parallel plane waves; and directing the plurality of plane waves from the collimator device towards a field of interest.
