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.

Respiratory-based biofeedback devices, systems, and methods are provided. A respiratory biofeedback method includes producing a respiratory signal in response to a user's respiratory activity, generating an audio output signal that includes a modified version of the respiratory signal, and converting the audio output signal into sound waves output to the user to provide biofeedback. The sound waves can be output to the user in real time response to the user's respiratory activity. A microphone can be used to generate the respiratory signal. The generated audio output signal can includes the respiratory signal modified to increase a volume level of a portion of the respiratory signal where the volume level exceeds a specified volume level.

Presented herein are techniques that can be used to track/monitor the health/well-being of an individual, such as person of an implantable medical prosthesis system, in a manner that protects the individual's privacy. In particular, a system in accordance with embodiments presented herein comprises one or more sensors configured to detect signals that may comprise one or more of external acoustic sounds and/or body noises (i.e., sounds originating from within the body of the person). The outputs from one or more sensors are analyzed to identify and categorize the individual's body noises present in the detected signals. The body noises are categorized in terms of the person's current/real-time activity.

A kit for dispensing disposable stethoscope covers and other instrument covers is provided. The kit may include a cartridge and a dispenser for automatic touch-free dispensing of disposable stethoscope covers. The kit further includes a first spool having a roll of backing member with disposable stethoscope covers disposed thereon and a second spool for receiving the spent backing member after a disposable stethoscope cover has been removed, self-contained within the cartridge. The cartridge is inserted within the dispenser so that a user may insert a stethoscope head through a window of the dispenser to attach to a disposable stethoscope cover. Alternatively, the cartridge or cassette may be comprised of disposable instrument covers so that a user may insert the instrument near or through the window of the dispenser for application of the instrument cover directly to the instrument. The kit may further include a proximity sensor for detecting a user.

An electronic skin is manufactured by disposing an oxide thin film transistor (TFT), a pressure sensor, and a temperature sensor on a flexible substrate. The pressure sensor and the temperature sensor are respectively located on two sides of the flexible substrate. The oxide TFT includes a first TFT and a second TFT. The pressure sensor is configured to drive the first TFT, and the temperature sensor is configured to drive the second TFT. The method for preparing the electronic skin is to form an oxide TFT, a pressure sensor, and a temperature sensor by means of etching and deposition on a flexible substrate whose double sides are covered with conductive materials. The electronic skin provided in the present invention may simultaneously measure pressure and temperatures, and has a simple structure, a low working voltage, small power consumption, high sensitivity, and small interference between sensor signals.

Embodiments described herein include sensors and sensor systems having probe-off detection features. For example, sensors and physiological monitors described herein include hardware and/or software capable of providing an indication of the integrity of the connection between the sensor and the patient. In various embodiments, the physiological monitor is configured to output an indication of a probe-off condition for an acoustic sensor (or other type of sensor). For example, in an embodiment, a signal from an acoustic sensor is compared with a signal from a second sensor to determine a probe-off condition.

Detecting chronotropic incompetence includes determining, using a processor, a baseline cardiac health measure for a user based upon an estimate of activity level for the user, validating, using the processor, the estimate of activity level for the user with a validation factor determined from sensor data and determining, using the processor, a cardiac health measure for the user from the sensor data. A signal indicating chronotropic incompetence for the user can be provided by the processor based upon a comparison of the cardiac health measure for the user with the baseline cardiac health measure.

Evaluating an implanted hearing prosthesis, including operating the implanted hearing prosthesis, capturing sound generated by a transducer of the prosthesis during said operation, and comparing the captured sound to a sound model.

A warming device for perioperative use includes a clinical garment and a convective thermal blanket supported on an inside surface of the clinical garment. A mechanism may be provided to releasably attach the thermal blanket to the clinical garment.

The subject matter is a patient supporting device for supporting a patient during a medical treatment, in particular a dialysis treatment, and a treatment apparatus with such a patient supporting device, and a corresponding method for controlling and/or regulating a medical treatment device, in particular a dialysis device, using such a patient supporting device.
