Abstract: Columnar multi-axis microelectromechanical systems (MEMS) devices (such as gyroscopes) balanced against undesired linear and angular vibration are described herein. In some embodiments, the columnar MEMS device may comprise at least two multiple-mass columns, each having at least three proof masses and being configured to sense rotation about a respective axis. The motion and mass of the proof masses may be controlled to achieve linear and rotational balancing of the MEMS device. The columnar MEMS device may further comprise one or more modular drive structures disposed alongside each multiple-mass column to facilitate displacement of the proof masses of a respective column. The MEMS devices described herein may be used to sense roll, yaw, and pitch angular rates.

Abstract: Aspects of the present disclosure include isolating a target scene object from multiple images of a time-of-flight (TOF) sensor. Multiple images from a TOF sensor can be transformed into multiple three-dimensional (3D) point clouds. In each of the multiple 3D point clouds, one or more large planes having a minimal threshold size can be identified. A common 3D point cloud can be generated by aligning rotated and translated point clouds corresponding to at least a portion of the multiple 3D point clouds. The common 3D point cloud can be rotated and translated to have one of one or more large planes identified as a ground plane within a common coordinate system of the common 3D point cloud, and a target object can be isolated.

Abstract: Aspects described herein relate to estimating mean arterial pressure (MAP) of a living being. The estimating may include obtaining pulsatile arterial blood pressure (pABP) waveform, obtaining arterial blood flow (ABF) waveform, identifying a set of segments of the pABP waveform in steady state, identifying a set of segments of the ABF waveform in steady state, and estimating the MAP based on the identified segment of the pABP waveform in steady state and the identified segment of the ABF waveform in steady state

Abstract: Herein disclosed are systems and circuitry for protecting against overdrive and electrostatic discharge. For example, protection circuitry may include field effect transistors to discharge overdrive outside of an operational voltage range of a circuit in some embodiments to prevent damage to the circuit. Further, the protection circuitry may utilize diode features inherent in the field effect transistors to protect against electrostatic discharge in some embodiments. The circuitry may be implemented in radio frequency sampling analog-to-digital converters and can provide for single-ended signal input and/or output for the analog-to-digital converters.
