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.

A system includes an electronic module containing an electronic component and a connector in communication with the electronic component, and a housing defining a chamber and having an opening providing access to the chamber to receive the electronic module. The housing has an interface for removable electronic connection to the connector of the module when the module is received in the chamber, and the housing further has a magnet connected to the housing. The module includes a sensor configured to sense the magnet when the module is received in the chamber, and the module is configured to deactivate the connector when the sensor does not sense the magnet and to activate the connector when the sensor does sense the magnet. The sensor may be a Hall effect sensor and/or the connector may be configured for connection to a USB port in various configurations.

A system includes one or more sensors to detect activities of a mobile object; and a processor coupled to the sensor and the wireless transceiver to classify sequences of motions into groups of similar postures each represented by a model and to apply the models to identify an activity of the object.

An apparatus for protecting a power tool user includes a glove or other garment having at least one sensor that monitors proximity to the power tool. Glove embodiments can include finger and/or thumb proximity sensors, and/or sensors that detect hand position, finger and/or wrist joint angle, vibration, and/or acceleration. Sensing targets can be retroactively installed on the power tool, and can define warning and/or danger zones. Sensing can be via magnetic, electromagnetic, capacitive, eddy current, and/or range finding means. Sizes of warning and/or target areas can be controlled by selecting targets from a plurality of targets of various detection ranges. Protective responses can vary according to different sensed events, and can include audible, visual, and/or tactile alerts, and/or interruption of power to the tool. Embodiments can record proximity and/or status data during a work session for review, training, and certification purposes. A controller can be physically cooperative with the garment.

A probe system includes a finger-mountable housing having a distal end and a proximal receptacle end. The proximal receptacle end defines an opening to receive a finger. The probe system also includes a probe assembly disposed on or within the finger-mountable housing and having at least a first sensor. The first sensor is positioned to measure a physical characteristic of a first tissue when the finger-mountable housing and probe assembly are inserted in a rectum of the patient.

Various embodiments relate to apparatuses and methods of using light transmission thought living tissue, such as a finger, to detect the flexure of a joint. Light is introduced into the tissue at one point, passes through the tissue, and exits the tissue at a second point where a sensor receives the light as it exits the tissue. Transmission of light through living tissue such as a finger can be affected by movement of the finger. As the finger flexes and, for example, the joints of the finger change angle, the characteristics of the light exiting the tissue, such as the intensity of the light, can change. These changes in characteristics can be used as an indirect means of determining the flexure of the joint.

Various systems are disclosed herein for detecting, monitoring, evaluating, and characterizing pain. They systems include a number of connected components, such as a provider device, a body-mapping system, a patient device, a user device, a referred pain device and/or a rectal probe device. Accordingly, the systems allow providers to track location-specific pain intensity for any number of patients over time in order to generate reports and determine treatment recommendations for such patients.

A glove is described to simultaneously, non-invasively, and continuously, over a period of time, monitor physiological parameters (e.g., blood pressure, blood glucose, oxygen saturation level, electrical activity of the heart, and/or heart rate) of a patient. A computing server that is either communicatively coupled to the glove or is a part of the glove uses the monitored physiological parameters to determine whether the patient has a physiological condition (e.g., hypotension, hypertension, hypoglycemia, hyperglycemia, hypoxia, hyperoxia, arrhythmia, a strong form of tachycardia, a mild form of tachycardia, and/or bradycardia). Related apparatuses, systems, methods, techniques and articles are also described.

A training system, kit, and method including a weighted wearable equipment, e.g. gloves, having a sensor (e.g. accelerometers, gyroscopes, photoelectric sensors, position sensors, tilt sensors, pressure sensors, temperature sensors, blood pressure sensors, heart rate monitors, and SpO2 sensors) and including a weight enhancement (e.g. weight bodies in closed pockets); a non-weighted wearable equipment of the same type as the weighted wearable equipment, the non-weighted wearable equipment having a sensor and. not including a weight enhancement; and a training application in functional communication with each of the weighted wearable equipment and the non-weighted wearable equipment and having a data processor that includes instructions for: analyzing data received from the sensor of each of the weighted wearable equipment and the non-weighted wearable equipment and generating predictive information derived from exercise training data from the sensors.

A system for providing a magnetic resonance treatment may include components that provide the system with an ability to treat pain and relieve symptoms of the subject. In another embodiment, a method of providing a magnetic resonance treatment includes components that provide the system with an ability to treat pain, relieve symptoms, provide relaxation, and improve the overall comfort and well-being of the subject.
