Patent number: 11047821Abstract: Accurately measuring bio-impedance is important for sensing properties of the body. Unfortunately, contact impedances can significantly degrade the accuracy of bio-impedance measurements. To address this issue, circuitry for implementing a four-wire impedance measurement can be configured to make multiple current measurements.

Patent number: 10736558Abstract: The present invention relates to methods for assessing swallowing motor function in a subject. The methods rely on obtaining intraluminal impedance and pressure measurements from the pharynx and/or esophagus of the subject during clearance of a bolus from the mouth and/or throat of the subject. The intraluminal impedance and pressure measurements are combined to derive a value for one or more pressure-flow variables in the pharynx and/or the esophagus of the subject. The value of the one or more pressure-flow variables is compared to a predetermined pharyngeal and/or esophageal reference value for the one or more pressure-flow variables in order to provide an assessment of swallowing motor function in the subject.Type: GrantFiled: April 14, 2017Date of Patent: August 11, 2020Inventors: Taher Imad Omari, Nathalie Rommel

Patent number: 10733266Abstract: Methods of selection of health related applications and treatment and diagnosis using health related applications are provided herein. Methods include selection of a first set of health related apps by a physician for use in treatment or diagnosis of a health condition, selection of an app from the first set by the patient with a first portable device. In one aspect, the applications are provided and managed by a service providers and include regulated health related apps. In some methods, the system communications with an insurer so as to indicate to a patient an insurance related attribute associated with each app to facilitate selection by the patient. In another aspect, methods include communication of health data elements obtained with the first portable device to the health service provider for tracking or analysis and subsequent communication between any of the first portable device and the service provider, insurer and physician.Type: GrantFiled: February 3, 2016Date of Patent: August 4, 2020Assignee: Apple Inc.Inventor: Todd K.

Patent number: 10702205Abstract: Apparatus and methods are described for setting rehabilitation goals for a patient, measuring patient movements, storing the movement data for later transfer to a computer, displaying progress indicators and inspirational messages based on progress towards goals, reporting movement, skin temperature and swelling data to a caregiver so that they monitor compliance and be aware of potential infection. The invention consolidates data from motion, temperature and swelling sensors placed on the patient with data received directly from the patient in response to questions displayed on a tablet computer screen, to create one or more representative values indicating the patient's current status. These representative values may include the patient's degree of compliance with their prescribed exercise and icing regimen; their degree of wellness based on their self-reported pain scale and sensed temperature and limb swelling; and their current level of physical activity as detected by the motion sensors.Type: GrantFiled: July 4, 2018Date of Patent: July 7, 2020Assignee: Claris Healthcare Inc.Inventors: Paul Sharman, Geof Auchinleck

Patent number: 10702184Abstract: Various examples are directed to a measurement system for measuring an electrical property of skin comprising an excitation circuit, a receiver circuit, and a sequencer circuit. The excitation circuit may generate a periodic excitation signal that, when provided to the skin, generates a response signal in the skin indicative of the electrical property. The sequencer circuit may be configured to activate the excitation circuit to provide the excitation signal to the skin. While the excitation circuit is activated to provide the excitation signal to the skin, the sequencer circuit may activate the receiver circuit to execute a first sample cycle to generate a first plurality of samples of the response signal. A first value for the electrical property of the skin may be determined based at least in part on the first plurality of samples of the response signal.Type: GrantFiled: June 7, 2017Date of Patent: July 7, 2020Assignee: Analog Devices International Unlimited CompanyInventors: Liam Riordan, José Carlos Conchell Añó, Tony Shi, Guangyang Qu, Hanqing Wang
