Patent number: 11207025Abstract: A wearable monitoring device can include an electronics module containing a printed circuit board (PCB) to which one or more sensors are coupled. The one or more sensors can include one or more contacting sensors and/or one or more non-contacting sensors. In some cases, the wearable monitoring device can include an onboard power supply (e.g., a battery) and a wireless communication antenna. The PCB can be constructed to specifically include the one or more sensors on a first side facing the skin of the user when the wearable monitoring device is being worn, allowing one or more processors, memory, and other components to be included on the opposite side facing away from the user. Certain components, such as the power supply and wireless communication antenna, can be spaced apart from the PCB and located opposite the PCB from the one or more sensors.Type: GrantFiled: January 28, 2021Date of Patent: December 28, 2021Assignee: ANEXA LABS LLCInventors: Ana Trapero Martin, Michael Daniel Vermeer, Mathew Asselin, Joel Steven Ironstone

Patent number: 11166635Abstract: A glucose monitoring system can make use of electrocardiograph (ECG) data and bioimpedance data acquired from a wearable device. The ECG data and bioimpedance data can each be processed to obtain a glucose level. These values can be processed together to obtain an adapted glucose value. In some cases, photoplethysmography data can also be used to assist in processing of the ECG data. The various types of data can be acquired from sensors on a wearable device. The wearable device can be removably coupled to a user's skin, such as via an adhesive substrate. In some cases, the wearable device can include a reusable electronics module that couples to replaceable electrodes on a replaceable adhesive substrate.Type: GrantFiled: January 28, 2021Date of Patent: November 9, 2021Assignee: ANEXA LABS LLCInventors: Ana Trapero Martin, Michael Daniel Vermeer, Mathew Asselin, Joel Steven Ironstone, Alexey Reykhert

Patent number: 11154204Abstract: A system for acquiring electrocardiograph (ECG) and bioimpedance (BI) data is disclosed. The system (an ECG/BI measurement system) can use as few as one or two pairs of electrodes, permitting wearable devices employing the ECG/BI measurement system to be made into smaller, more comfortable, and more inconspicuous formats, as well as decreasing potential failure points in the measurement of electrical signals conducted between the system and the user. The system can measure both ECG and BI data using at least one shared pair of electrodes. In some cases, ECG and BI data are separately extracted from a measured signal across a shared pair of electrodes, while another pair of electrodes is being driven with a supply current. In other cases, internal switching can automatically switch a pair of electrodes between ECG-measuring circuitry and BI-measuring circuitry, such as based on a clock signal or other trigger.Type: GrantFiled: January 28, 2021Date of Patent: October 26, 2021Assignee: ANEXA LABS LLCInventors: Ana Trapero Martin, Michael Daniel Vermeer, Mathew Asselin, Joel Steven Ironstone, Alexey Reykhert

Publication number: 20040243018Abstract: A system and method for diagnosing the possibility of disease in a body part is described. The system includes an electrode array containing a plurality of electrodes capable of being electrically coupled to the body part. A first measurement unit makes an electrode assessment measurement with the electrode array. An electrode assessment module determines whether the plurality of electrodes are suitably coupled to the body part based on the electrode assessment measurement. If there is suitable coupling, a second measurement unit makes a diagnosis measurement with the electrode array. An electrical property module obtains an electrical property of the body part, such as impedance, based on the diagnosis measurement. A diagnosis module diagnoses the possibility of disease based on the measured electrical property.Type: ApplicationFiled: November 28, 2003Publication date: December 2, 2004Applicant: Z-Tech (Canada) Inc.Inventors: Leslie William Organ, Kenneth Carless Smith, Joel Steven Ironstone
