Systems and methods are provided for controlling infrared radiation (IR) sources of a sauna including tuning IR wavelength-ranges and radiated power-levels of IR sources, and directing IR to locations on a user's body. In one illustrative embodiment, a sauna may be provided having adjustable IR emitters to emit IR at any wavelength resulting in a desirable radiation treatment for the sauna user. In another illustrative embodiment, a method is provided for tuning IR emitters in a sauna.

A flow sensor system for ventilation treatment comprises a flow conduit configured to allow gas flow between a first region and a second region, the flow conduit defining a lumen for the gas flow; a flow restrictor disposed within the lumen of the flow conduit between the first region and the second region; a first absolute pressure sensor disposed adjacent to the first region of the flow conduit and configured to measure a pressure of the gas flow at the first region of the flow conduit; and a second absolute pressure sensor disposed adjacent to the second region of the flow conduit and configured to measure pressure of the gas flow at the second region of the flow conduit.

Methods for treating fluid overload in a subject comprise shifting fluids directly and non-invasively from an interstitial compartment of the subject to skin of the subject through controlled local sweating. Methods of the invention allow for removal of excess fluid from the interstitial compartment of the subject and treat fluid overload in the subject. Sweat stimulation systems comprise a chamber and first and second relative humidity sensors. The chamber is sized to fit around a body part of a subject, comprises an inlet and an outlet, and is configured such that air flows through the chamber from the inlet to the outlet. The first relative humidity sensor is operably located inside the inlet, and the second relative humidity sensor is operably located proximate the outlet.

A spa is provided including a frame, a shell mounted to the frame defining a basin for holding water, at least one sensor for monitoring a spa component or water condition, a communications interface including a cellular transceiver, and a battery for providing power to the at least one sensor and to the communications interface when the spa is not connected to a power source. The spa also includes a controller in electrical communication with the at least one sensor and the communications interface. The controller is configured to, while the spa is not connected to the power source, receive information from the at least one sensor, process the received information, and cause the communications interface to wirelessly transmit the processed information to a remote source or central server.

An apparatus, system, and method involving controlling a spa system having a basin are provided. In one embodiment, the apparatus or system includes an electronics control portion and smart embedded software for receiving inputs from an operator of the spa system and for generating signals in response to inputs received from the operator. In addition, the apparatus or system includes a fluid mixing portion that receives the fluid from a supply and outputs the received fluid into the basin of the spa system. Moreover, the electronics control portion reads a temperature of the fluid in the fluid mixing portion and displays it to the control keypad. In another embodiment, the system includes a pump having a contactless, water sensor for dispensing water or air to a setting and for use with a disposable liner. The pump includes a jet assembly, a motor assembly, and a contactless, water sensor.

A method for treating chest wall injuries, including rib fractures, flail chest injuries or surgical incisions. The method comprising creating a localized airtight compartment external to the chest wall and fully covering the area of injury, varying the pressure within the compartment, and providing dynamic real-time counter forces that act reciprocal to the intrathoracic pressure changes that occur during ventilation. In a preferred embodiment, the apparatus has the capability of sensing the patient's chest wall motion created by ventilation, a pressure control component capable of varying the pressure within the airtight compartment such that it opposes pressure changes within the chest. The apparatus would be particularly useful in preventing the paradoxical movement of flail chest injuries. The method would also lessen pain experienced by patients with thoracic injuries such as rib fractures and post operative suffering.

The movement inducing device includes a plurality of air bags, each being provided with a contacting portion configured to contact with a user and induce a movement of an intended skeletal muscle of the user; a drive mechanism configured to expand and compress the air bags by adjusting supply and discharge of air to and from each air bag and a control unit provided with a drive control unit configured to control driving of the drive mechanism to make the intended skeletal muscle of the user perform at least one of an isotonic muscle activity, an isometric muscle activity and an isokinetic muscle activity.

Systems and methods for a wearable exoskeleton include an inflatable actuator with a reduced operation volume for faster operation. The inflatable actuator may include a first paddle connectable to the human body, a second paddle connectable to the human body, and an inflatable fabric coupled between the first paddle and the second paddle. In response to the inflatable fabric being filled with compressed air, the rigidity of the inflatable fabric increases, causing the angle between the first paddle and the second paddle to change to provide an assistive force for a movement of the human body. A portable pneumatic source is provided for quickly supplying a compressed air to the inflatable actuator. The portable pneumatic source may include a double acting piston and a cylinder defining a first chamber and a second chamber, and a valve assembly, for compressing air at both the upstroke and downstroke of the piston.

A medical emergency equipment including a load-bearing frame defining at least one supporting surface for a patient's back, at least one of a defibrillator and a device/unit/component for cardiac massage associated with the frame, a circuit configured for the extracorporeal circulation associated with the frame and operatively connected to the at least one of a defibrillator.

Systems and methods for providing network connectivity and remote monitoring, optimization, and control of pool/spa equipment are provided. “Internet-of-Things” (IoT) functionality is provided for pool and spa equipment in a flexible and cost-effective manner. Network connectivity and remote monitoring/control of pool and spa equipment is provided by various components such as a network communication and local control subsystem installed in pool/spa equipment, and other components. Also disclosed are various control processes (“pool logic”) which can be embodied as software code installed in any of the various embodiments of the present disclosure.
