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
