Abstract: Described herein is an accelerometer that can be sensitive to acceleration, but not anchor motion due to sources other than acceleration. The accelerometer can employ a set of electrodes and/or transducers that can register motion of the proof mass and support structure and employ and output-cancelling mechanism so that the accelerometer can distinguish between acceleration and anchor motion due to sources other than acceleration. For example, the effects of anchor motion can be cancelled from an output signal of the accelerometer so that the accelerometer exhibits sensitivity to only acceleration.

Abstract: Systems and methods for human hand gesture recognition through a training mode and a recognition mode are disclosed. In the training mode, a user can move a handheld device with a hand gesture intended to represent a command. Sensors within the handheld device can record raw data, which can be processed to obtain a set of values corresponding to a set of discrete features, which is stored in a database and associated with the intended command. The process is repeated for various hand gestures representing different commands. In the recognition mode, the user can move the handheld device with a hand gesture. A computer system can compare a set of values corresponding to a set of discrete features derived from the hand gesture with the sets of values stored in the database, select a command with the closest match and displays and/or executes the command.

Abstract translation: 这里描述的是加速度计，其可以对加速度敏感，但是不是由于加速度以外的源而是锚定运动。 加速度计可以使用一组电极和/或换能器，其可以记录检测质量块和支撑结构的运动并采用和输出消除机构，使得加速度计能够区分由加速度以外的源而导致的加速度和锚运动。 例如，可以从加速度计的输出信号中消除锚定运动的影响，使得加速度计仅对加速度表现出灵敏度。
