Patent number: 10327653Abstract: A method and apparatus for monitoring heart rate. The method includes receiving a digital heart monitoring signal, determining the integrity of said signal with a “hand detect” signal that confirms electrical connection to the subject, dividing the digital heart monitoring signal into at least one frame, generating a folded correlation value for the center sample in the at least one frame, identify the number of peaks folded correlation values based on amplitude and distance parameters of the digital heart monitoring signal in the at least one frame, removing false peaks and collecting peaks corresponding to a length of time, determining the heart rate based on the identified peaks wherein the identified peaks relate to a minimum distance between valid heart beat peaks based on a heart rate estimate, computing the weighted average of heart rate value based on the number of previous heart rate values.Type: GrantFiled: November 6, 2017Date of Patent: June 25, 2019Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Steven T. Dunbar, Sourabh Ravindran

Patent number: 7746804Abstract: A wireless communications network which provides directed transmissions between components of the network is provided. The components within the wireless communications include a master apparatus, a plurality of remote devices, and a plurality of repeaters. The components within the wireless communications network communicate using messages which have a control field and at least one information field. Information within the control field is used by components to make determinations for retransmitting the message, or transmitting a predefined response to the message, such as a signal strength response. The components within the network use the messages to make a determination of a communications target, which may be used as a primary contact for transmitting information, automatically, and may repeat the determination at predetermined intervals.Type: GrantFiled: September 13, 2006Date of Patent: June 29, 2010Assignee: Inovonics CorporationInventors: Neal Shurmantine, Daryl Burkhard, Steven T. Dunbar, Donald J. Hume, Nathan Koonce, Steve Koonce, Preston Pierce
