Patent number: 8721555Abstract: Photoplethysmography (PPG) is obtained using one red (e.g., 660 nm) and one infrared (e.g., 880 to 940 nm) light emitting diode with a single photo diode in combination with a pressure transducer thereby allowing both CVP and SpO2 to be measured simultaneously. The system also includes sensors capable of measuring position, angle and/or movement of the sensor or patient. Once the PPG signal is acquired, high pass adaptive and/or notch filtering can be used with one element of the filter from the red and infrared signals used to measure the arterial changes needed to compute SpO2 and the other element of the signal can be used to measure CVP changes.Type: GrantFiled: February 18, 2010Date of Patent: May 13, 2014Assignee: Watermark Medical, Inc.Inventors: Philip R. Westbrook, Daniel J. Levendowski, Timothy Zavora, Djordje Popovic, Milenko Cvetinovic, Chris Berka

Patent number: 7297119Abstract: In a technique for collecting and analyzing physiological signals to detect sleep apnea, a small light-weight physiological monitoring system, affixed to a patient's forehead, detects and records the pulse, oximetry, snoring sounds, and head position of a patient to detect a respiratory event, such as sleep apnea. The physiological monitoring system may contain several sensors including a pulse oximeter to detect oximetry and pulse rate, a microphone to detect snoring sounds, and a position sensor to detect head position. The physiological monitoring system also can contain a memory to store or record the signals monitored by the mentioned sensors and a power source. The physiological monitoring system may be held in place by a single elastic strap, thereby enabling a patient to use the system without the assistance of trained technicians.Type: GrantFiled: August 25, 2004Date of Patent: November 20, 2007Assignee: Ares Medical, Inc.Inventors: Philip R.

Patent number: 6985034Abstract: The main difference between the boost bridge amplifier according to this invention and state of the art class D amplifiers is in the connection of a load between a power supply and a switching bridge which is supplied from a bridge capacitor. The switching bridge operation is controlled by the pulse-width modulated control signals. Thereby, it is possible to completely eliminate both input and output filters, which are required in state of the art class D amplifiers. It is also possible to achieve several times higher power at the load, due to the additional switching bridge supply from the bridge capacitor. Conducted and radiated EMI noise is significantly reduced in comparison with state of the art class D amplifiers. This embodiment provides a low price, small size and low EMI noise level.Type: GrantFiled: June 7, 2000Date of Patent: January 10, 2006Inventors: Milan Prokin, Milenko Cvetinovic

Patent number: 6646507Abstract: The main difference between the power booster amplifier according to this invention and state of the art class D amplifiers is in the connection of a load between a power supply and a switching half bridge which is supplied from a bridge capacitor. The switching half bridge operation is controlled by pulse-width modulated control signals. Thereby, it is possible to completely eliminate both input and output filters which are required in state of the art class D amplifiers. It is also possible to achieve several times higher power at the load due to the additional supply from the bridge capacitor for the switching half bridge. The conducted and radiated EMI noise is significantly reduced in comparison with state of the art class D amplifiers. This embodiment provides a low price, small size and low EMI noise level.Type: GrantFiled: May 22, 2002Date of Patent: November 11, 2003Inventors: Milan Prokin, Milenko Cvetinovic
