Patent number: 9095268Abstract: The described embodiments relate generally to methods, systems and devices for sleep stage determination using frontal electrodes. Certain embodiments relate to a system for sleep stage determination comprising a sensing unit and a processing unit. The sensing unit is positioned over a forehead area of a patient and has first, second and third electrodes for positioning at locations on or adjacent the forehead area for detecting electrical potentials of a human head. The processing unit is coupled to the sensing unit for receiving biological signals corresponding to the detected electrical potentials and processing the biological signals to determine a sleep stage of the patient. The processing of the biological signals is based on a plurality of rules.Type: GrantFiled: July 9, 2012Date of Patent: August 4, 2015Assignee: Natus Medical IncorporatedInventors: Ronald Leon Kurtz, Jianping Wu, Aaron Phillip Weinroth

Patent number: 8805527Abstract: Embodiments of the invention relate to a wireless physiological monitoring system. The system includes at least one wireless sensor and a monitoring device which are linked to one another of a wireless fashion for measuring physiological signals of a patient. The at least one wireless sensor is located on the patient and may comprise a wireless surface electrode assembly or a wireless needle assembly. The system may also comprise a wireless stimulator synchronized with the wireless sensor for performing certain diagnostic tests, such as nerve conduction velocity tests, for example. The wireless sensor preferably includes active, reference and common conductors. The common conductor can be used to measure the common mode voltage of the patient in the vicinity of the testing, and this voltage can then be subtracted from the measured active and reference voltages.Type: GrantFiled: December 10, 2008Date of Patent: August 12, 2014Assignee: Natus Medical IncorporatedInventors: John Robert Mumford, Ronald Leon Kurtz

Patent number: 7575005Abstract: Embodiments of the invention relate to a mask assembly for use in treatment systems for treating obstructive sleep apnea using continuous positive air pressure (CPAP). The mask assembly comprises a mask or nasal interface for supplying gas to the nose of a wearer of the mask assembly. The mask assembly also comprises a strap or harness attached to the mask for securing the mask assembly to the wearer and sensors located on the mask assembly for measuring physiological signals of the wearer. These physiological signals are communicated to a monitoring unit which, in association with a CPAP device, serves to determine the efficacy of the CPAP treatment and to vary operational parameters of the treatment.Type: GrantFiled: May 18, 2005Date of Patent: August 18, 2009Assignee: Excel-Tech Ltd.Inventors: John Robert Mumford, Ronald Leon Kurtz, Jianping Wu

Publication number: 20090105577Abstract: Embodiments relate to devices for detecting electrical potentials corresponding to biological signals. The device comprises a flexible member for positioning over a forehead area of a human head and first, second and third electrodes located on the flexible member. The first electrode is located in a projecting portion of the flexible member to be positioned adjacent a nasion area of the head. The second electrode is to be positioned over a first lateral forehead area. The third electrode is to be positioned over a second lateral forehead area opposite the first lateral forehead area.Type: ApplicationFiled: November 17, 2008Publication date: April 23, 2009Inventors: Jianping Wu, Ronald Leon Kurtz

Patent number: 7283866Abstract: Embodiments of the invention generally relate to needles having more than one electrode and which are particularly suited for use in electromyography. One embodiment relates to a tripolar needle having three concentric electrodes. The tripolar needle is formed by providing a needle blank having first and second concentric electrodes and forming a third concentric electrode around the needle blank. The tripolar needle has an outer diameter which is substantially constant along the shaft of the needle, except at the tip, where the needle is sharpened.Type: GrantFiled: May 17, 2005Date of Patent: October 16, 2007Assignee: Hatch LtdInventors: John Robert Mumford, Ronald Leon Kurtz
