  • Patent number: 10499022
    Abstract: Disclosed herein is a MEMS device including a fixed structure, a mobile structure, and deformable structures extending therebetween. The deformable structures have first ends anchored along X and Y axes of the fixed structure, and have second ends anchored offset from the X and Y axes of the fixed structure. The deformable structures are shaped so as to curve from their anchoring points along the mobile structure back toward the mobile structure, to extend along the perimeter of the mobile structure, and to then curve away from the mobile structure and toward their anchoring points along the fixed structure. Each deformable structure has two piezoelectric elements that extend along the length of that deformable structure, with one piezoelectric element having a greater length than the other piezoelectric element.

  • Patent number: 10484217
    Abstract: An occurrence of a first set of n periods of a frequency-shift-keying (FSK)-modulated waveform is counted, where n is an integer number. The n periods of the FSK-modulated waveform in the first set have a first time duration. An occurrence of a second set of n periods of the waveform is counted. The n periods of the waveform in the second set have a second time duration. The first time duration is determined based on the counting of the first set of n periods. The second time duration is determined based on the counting of the second set of n periods. A difference between the first time duration and the second time duration is compared to a threshold. Changes in frequency of the waveform are detected based on the comparing of the difference between the first time duration and the second time duration to the threshold.

  • Patent number: 10483238
    Abstract: An integrated circuit package with improved reliability and methods for creating the same are disclosed. More specifically, integrated circuit packages are created using one or more sacrificial layers that provide support for ink printed wires prior to package processing, but are removed during package processing. Once each of the sacrificial layers is removed, molding compound is placed around each ink printed wire, which may have a substantially rectangular cross section that can vary in dimension along a length of a given wire. While substantially surrounding each wire in and of itself improves reliability, removing non-conductive paste, fillets, or other adhesive materials also minimizes adhesion issues between the molding compound and those materials, which increases the bond of the molding compound to the package and its components. The net result is a more reliable integrated circuit package that is less susceptible to internal cracking and wire damage.
