  • Publication number: 20200229710
    Abstract: Motion activity data is collected from at least one sensor. An initial motion activity classifier function is applied to the motion activity data to produce an initial motion activity posteriorgram. Pre-processing and segmenting the motion activity data into windows produces segmented motion activity data from which sensor specific features are extracted. An updated motion activity classifier function is generated from the extracted sensor specific features. Subsequent motion activity data is also collected from the at least one sensor, and the updated motion activity classifier function is applied to the subsequent motion activity data to produce an updated motion activity posteriorgram.

  • Publication number: 20200235660
    Abstract: A charge pump circuit generates a charge pump output signal at a first node and is enabled by a control signal. A diode has an anode coupled to the first node and a cathode coupled to a second node. A current mirror arrangement sources a first current to the second node and sinks a second current from a third node. A comparator causes the control signal to direct the charge pump circuit to generate the charge pump output signal as having a voltage that ramps upwardly in magnitude (but negative in sign) if the voltage at the second node is greater than the voltage at the third node, and causes the control signal to direct the charge pump circuit to cease the ramping of the voltage of the charge pump output signal if the voltage at the second node is at least equal to the voltage at the third node.

  • Publication number: 20200235659
    Abstract: A charge pump circuit generates a charge pump output signal at a first node and is enabled by a charge pump control signal. A diode has first and second terminals coupled to first and second nodes. A comparator has an inverting input coupled to the second node and a non-inverting input coupled to a third node, and causes generation of the charge pump control signal. A first current mirror produces a first current at the second node, and a second current mirror produces a second current (equal in magnitude to the first current) at the third node. The first terminal and second terminals may be a cathode and an anode. The first current mirror may be a current sink sinking a first current from the second node. The second current mirror may be current source sourcing a second current (equal in magnitude to the first current) to the third node.

  • Publication number: 20200235702
    Abstract: A clock signal is generated with an oscillator. A crystal oscillator core within the oscillator circuit is switched on to produce first and second oscillation signals that are approximately opposite in phase. When a difference between a voltage of the first oscillation signal and a voltage of the second oscillation signal exceeds an upper threshold range, the crystal oscillator core is switched off. When the difference between the voltage of the first oscillation signal and the voltage of the second oscillation signal falls below the upper threshold range, the crystal oscillator core is switched back on. This operation is repeated so as to produce the clock signal.

    Abstract: A rotary element is equipped with a pattern representing a reflected binary code on at least three bits. A detection circuit is configured to sense the pattern and deliver an incident signal encoded in reflected binary code on at least three bits. The incident signal is converted by a transcoding circuit into an intermediate signal encoded in reflected binary code on two bits. A decoding stage decodes the intermediate signal and outputs at least one clock signal representing the amount of rotation of the rotary element and a direction signal representing the direction of rotation. A processing circuit determines the movement of the rotary element, and has at least one general purpose timer designed to receive the at least one clock signal and direction signal.
