US Patent:

20190339806, Nov 7, 2019

Filed:

Jul 15, 2019

Appl. No.:

16/512020

Inventors:

- Dallas TX, US
Steve Kummerl - Carrollton TX, US
Mark Stephen Toth - Murphy TX, US
Alok Lohia - Dallas TX, US
Terry Lee Sculley - Lewisville TX, US
Seung Bae Lee - Dallas TX, US
Scott Robert Summerfelt - Garland TX, US

International Classification:

G06F 3/041

Abstract:

An integrated force sensing element includes a piezoelectric sensor formed in an integrated circuit (IC) chip and a strain gauge at least partially overlying the piezoelectric sensor, where the piezoelectric sensor is able to flex. A human-machine interface using the integrated force sensing element is also disclosed and may include a conditioning circuit, temperature gauge, FRAM and a processor core.

Srinath Ramaswamy - Murphy TX, US

International Classification:

H04B 1/10

Abstract:

Reduced noise and power with rapid settling time and increased performance in multi-modal analog multiplexed data acquisition systems. An example apparatus arrangement includes a circuit input configured to receive a plurality of analog input signals; an analog to digital converter circuit configured to output a digital representation of an analog voltage; a selection circuit configured to select one of the analog input signals received at the circuit input; a buffer coupled to receive the selected one of the analog input signals; a filter coupled to the buffer and configured to perform a high bandwidth sample operation and a low bandwidth sample operation and having a filter output, responsive to a control signal; and a sampling capacitor coupled to the filter to sample the filter output, and having an output coupled to the analog to digital converter. Methods and additional apparatus arrangements are disclosed.

International Classification:

A61B 5/024
A61B 5/00

Abstract:

The circuitry of an optical receiver reduces the ambient DC component and the pleth DC component to leave a pleth signal with substantially only a pleth AC component. The circuitry also provides gain control and can provide transmit power control to change the range of the pleth AC component to occupy a desired input range of an analog-to-digital converter.
