The present invention furthermore relates to a system (110) for assessing hearing ability of a subject (20).

Configurations are disclosed for a health system to be used in various healthcare applications, e.g., for patient diagnostics, monitoring, and/or therapy. The health system may comprise a light generation module to transmit light or an image to a user, one or more sensors to detect a physiological parameter of the user's body, including their eyes, and processing circuitry to analyze an input received in response to the presented images to determine one or more health conditions or defects.

A system for detecting bioelectrical signals of a user comprising: a set of sensors configured to detect bioelectrical signals from the user, each sensor in the set of sensors configured to provide non-polarizable contact at the body of the user; an electronics subsystem comprising a power module configured to distribute power to the system and a signal processing module configured to receive signals from the set of sensors; a set of sensor interfaces coupling the set of sensors to the electronics subsystem and configured to facilitate noise isolation within the system; and a housing coupled to the electronics subsystem, wherein the housing facilitates coupling of the system to a head region of the user.

A device for exploring the visual system, comprising portable viewing equipment having at least one viewing screen configured to be placed facing at least one eye of a person. The viewing equipment comprises sealing lips surrounding the viewing screens and having a free edge intended to be applied against the skin of the person, this free edge comprising at least one electrode for measuring the electrical potential. The device also comprises at least one free electrode for measuring the electrical potential, which free electrode is linked by a connecting wire to a connector carried by the viewing equipment, between one of the viewing screens and the free edge of the sealing lips surrounding this screen.

Hat, helmet, and other headgear apparatus includes dry electrophysiological electrodes and, optionally, other physiological and/or environmental sensors to measure signals such as ECG from the head of a subject. Methods of use of such apparatus to provide fitness, health, or other measured or derived, estimated, or predicted metrics are also disclosed.

The provided systems, methods and devices describe lightweight, wireless tissue monitoring devices that are capable of establishing conformal contact due to the flexibility or bendability of the device. The described systems and devices are useful, for example, for skin-mounted intraoperative monitoring of nerve-muscle activity. The present systems and methods are versatile and may be used for a variety of tissues (e.g. skin, organs, muscles, nerves, etc.) to measure a variety of different parameterps (e.g. electric signals, electric potentials, electromyography, movement, vibration, acoustic signals, response to various stimuli, etc.).

A system includes a controllable device configured to provide a premises related service in an area. The system includes a neural device to be positioned with respect to a part of a body of a user and circuitry to process nerve signals detected in real-time. The system also includes a processor in communication with the circuitry, a memory and instructions stored in the memory for execution by the processor. Data stored in the memory associates each of some number of predetermined sets of nerve signals with a control instruction. Execution of the instructions configures the processor to use the stored data to analyze the real-time detected nerve signals to determine when real-time detected nerve signals correspond to one of the predetermined sets of nerve signals and generate a control data signal based on the associated control instruction to cause a controller to control an operation of the controllable device.

A portable polysomnography apparatus comprises a unitary flexible structured pillow that is embedded with accelerometers for data collection. The polysomnography apparatus is advantageously sized and shaped to cause the sleeping subject to properly orient the embedded accelerometers for optimal data collection while the subject is asleep. A portable polysomnography system comprises a structured pillow with embedded sensors that are in wireless communication with a companion data collection device that records data from the embedded sensors. In an alternative embodiment, a system may include a structured pillow with an internal pocket into which a single device including embedded sensors and data recording capabilities is inserted.
