Abstract: A device including an array of electrodes generates one or more electrical signals from a user, extracts one or more noise signals, and generates one or more de-noised electrical signals upon processing the electrical signal(s) with the noise signal(s). The array of electrodes is coupled to a surface of the device, where the device also includes force sensors in mechanical communication with the surface for detecting user weight and other forces. The device can be configured to generate electrical signals from different subportions of the array of electrodes and to extract noise signals from different subportions of the array of electrodes, where the subportion(s) for electrical signal generation may or may not overlap with the subportion(s) of electrodes for noise signal extraction.

Abstract: A device for simultaneously acquiring electrocardiogram (ECG) signals, impedance plethysmogram (IPG) signals, ballistocardiogram (BCG) signals, and weight measurements through feet of a user. The device includes an electrically-conductive surface for contacting feet of the user and supporting weight of the user during use. The device also includes one or more force sensors for detecting forces and force variations across the electrically-conductive surface, electronics for processing electrical signals generated and/or detected from the electrically conductive surface, signals from the set of force sensors, and a base containing the electronics. The base is structurally coupled to the electrically-conductive surface by a set of conductive fasteners that transmit signals from the electrically-conductive surface to the electronics. The device can also include an integrated display for providing health insights to the user.

Abstract: Collectively, the electrical signal(s) and the force-associated signal(s) generated by sensors of the device are processed by a computing subsystem with electronics and architecture configured for sensor fusion and extraction of composite features indicative of cardiovascular health states. In one or more embodiments, the device generates electrocardiogram (ECG) signals, impedance plethysmogram (IPG) signals, ballistocardiogram (BCG) signals, and weight measurements through an interface with feet of a user. Computing subsystem components fuse the ECG, IPG, and BCG data to efficiently generate analyses of cardiovascular health of the user, in relation to various parameters related to temporal components of cardiac phases, force and volume-associated parameters, and other relevant parameters. The parameters are regularly collected and analyzed to monitor user cardiovascular health and trigger preventative health interventions.

Abstract: A device for measuring a biological signal, including a cardiovascular signal. The device includes a force sensor positioned to measures a biological signal as a varying force exerted on the device and/or electrical signal sensors that cooperate with each other to measure a biological signal as an electrical signal sensed from the user. The device includes a processor that receives the biological signal, determines, from the biological signal, one or more biological parameters, and generates output representative of the one or more biological parameters.

Abstract: Embodiments of the invention provide a facility for measuring critical CPR parameters during first aid training. Specifically, the device provides a manikin housing for the insertion of a consumer electronic device such as phone, music player, personal assistant, game controller or other device with necessary sensory for the measurement of the CPR parameters. Tactile buttons, touch sensitive displays and embedded accelerometers in these devices may be used to accurately measure CPR parameters. In certain embodiments, parameters may be measured using a game console controller and the feedback may be displayed on a television in the form of a video game.
