Patent for Analog Data Transmission Circuit via Bus
Summary
The USPTO has published a new patent application, US20260086970A1, for a low voltage drive circuit for transceiving analog data via a bus. The application was filed by SigmaSense, LLC. and assigned to inventors Richard Stuart Seger, JR., Daniel Keith Van Ostrand, Gerald Dale Morrison, and Timothy W. Markison.
What changed
The United States Patent and Trademark Office (USPTO) has published patent application US20260086970A1, titled "LOW VOLTAGE DRIVE CIRCUIT FOR TRANSCEIVING ANALOG DATA VIA A BUS AND METHODS FOR USE THEREWITH." The application, filed by SigmaSense, LLC., details a circuit that converts digital data into analog outbound data for transmission over a bus, and receives analog inbound data. The invention focuses on generating analog outbound data by combining a DC component with an oscillating component, where the oscillating component is derived from transmit digital data. The analog transmit signal represents outbound data through bus loading variances at a first frequency, and inbound data through variances at a second frequency.
This publication represents a new patent application and does not impose immediate compliance obligations on regulated entities. However, companies involved in developing or manufacturing data transmission circuits, particularly those dealing with analog signals over buses, should be aware of this filing. The assignee, SigmaSense, LLC., is the primary party of interest. Further developments, such as patent grant or licensing, may impact the technology landscape in this area.

Abstract
A low voltage drive circuit includes a transmit digital to analog circuit that converts transmit digital data into analog outbound data by: generating a DC component; generating a first oscillation at a first frequency; generating a second oscillation at the first frequency; and outputting the first oscillation or the second oscillation on a bit-by-bit basis in accordance with the transmit digital data to produce an oscillating component, wherein the DC component is combined with the oscillating component to produce the analog outbound data, and wherein the oscillating component and the DC component are combined to produce the analog outbound data. A drive sense circuit drives an analog transmit signal onto a bus, wherein the analog outbound data is represented within the analog transmit signal as variances in loading of the bus at the first frequency and wherein analog inbound data is represented within an analog receive signal as variances in loading of the bus at a second frequency.
