Powered chairs, assemblies for use in the powered chairs, and components for use in the assemblies are provided. Electrical systems for use in the powered chairs, and components for use in the electrical systems are provided. Control systems and methods for operating powered chairs are also provided. Any given chair may be locally and/or remotely controlled.

A device and method are provided for therapy and treatment of biological tissue such as muscle, tendon, and ligament tissue, by use of a device and method in which therapeutic vibrational frequency resonance patterns are transmitted to tissues of a patient. The resonance frequencies originate from many resonance domains, including vitamins, minerals, herbs, amino acids, and fatty acids. Each domain includes therapeutic frequency resonance patterns. These resonance patterns may be passively excited and transmitted to a patient to enhance tissue function, to decrease the normal rehabilitation time of damaged tissue, and provide therapeutic benefits for muscle tissue dysfunction. Therapeutic frequency resonance patterns may also be actively excited by a delivery mechanism that uses electromagnetic or mechanical waves to interact with the device. The actively excited device transmits the therapeutic frequency resonance patterns to the patients for similar enhancements and therapeutic benefits.

The disclosure generally relates to an adjustable bed, in particular incorporating improved power management systems. In various embodiments, an adjustable bed can include a wirelessly chargeable remote control unit, one or more pulse width modulator units to provide DC power at a variety of voltages appropriate for varied peripheral electrical components of the bed, and/or a battery backup unit providing power to the bed in addition to a mains power input. The various power management systems can reduce wire clutter for peripheral electrical components, permit a wider range of peripheral electrical components to be driven by a single power supply, provide for adjustable bed operation in the absence of mains power supply, and reduce power consumption in different operation modes.

An automatic massage apparatus may include a main body, a massaging unit, at least two first belts and at least two second belts. The main body has a guiding rail that is hollow to provide a space for a driving unit of the massaging unit, and a long groove is formed on both sides of the guiding rail. The massaging unit has a driving unit that has a driving shaft extending towards both sides of the driving unit. Both ends of the driving shaft have a plurality of wheels disposed against the rail of the main body, and these wheels are appropriately spaced. Both sides of the massaging unit have at least one compartment and a second compartment. One end of the first belt is secured on the first end of the positioning unit, and the other end is wrapping the driving shaft in the first compartment.

A multimodal wearable band uses mechanical vibrations to stimulate sensory neurons in the wrist or ankle to reduce the severity of tremors, rigidity, involuntary muscle contractions, and bradykinesia caused by neurological movement disorders and to free users from freezing induced by movement disorders. The device uses sensors to provide output used by a processing unit to determine a stimulation pattern for the user and to determine when stimulation is necessary, and then uses one or more transducers to correspondingly stimulate the user’s neurological pathways to lessen the severity of the user’s symptoms. The device can also be adapted to integrate with third party devices.

The present disclosure pertains to a system configured to determine one or more parameters of chest wall oscillation therapy for a subject. The system includes a wearable garment configured to provide percussion to one or more parts of a lung of a subject. The wearable garment includes: percussion excitation elements configured to produce the percussion; and sensors configured to generate output signals conveying information related to a response of the one or more parts of the lung to the percussion. The system includes a control unit configured to determine frequency and energy density information for the sounds made by the one or more parts of the lungs caused by the percussion, the frequency and energy density information determined based on the output signals; and determine the one or more parameters of the chest wall oscillation therapy based on the frequency and energy density information.

A massage device for use in a seat including at least one massage head, which is configured to provide a massage function in at least one sub-region of a seat, and a sensor device, which is configured to detect a contact of the seat by a user in the at least one sub-region of the seat. The massage device is configured to actuate the massage head at least in part depending on a sensor signal which is generated by the sensor device and which indicates a contact by the user in the at least one sub-region of the seat.

Air cushion assembly for a seat, such as a vehicle seat, comprising at least an air cushion and an air supply system for variably pressurizing the air cushions of the air cushion assembly with air. A respective supply line comprising a shut-off valve leads from the air supply system to each air cushion, where a pulsation module is provided and configured to act upon each air cushion with a pulsation. The pulsation module comprises a pneumatic element which is connected in a pressure-equalized manner to at least one supply line, and an actuating element for transmitting a mechanical motion to the pneumatic element for changing the volume of the pneumatic element in order to generate a pulsation.

A therapeutic device for treating conditions of a user's nasal cavities, sinuses, and/or ear canals includes a housing which the user may hold to apply the therapeutic device to the user, the housing including an inlet that allows air to enter the therapeutic device. An acoustic vibrator located within the housing provides an acoustic vibration to the user, and a power supply located within the housing provides power to the acoustic vibrator. A mask is connected to the housing and includes a nasal interface that is appliable around the nose of the user. A valve of the mask opens to allow the user to breathe through the inlet and closes to prevent the user from exhaling through the inlet. The mask further includes a diaphragm and a nasal cavity in which a user's nostrils are located when the nasal interface is applied to the user.

A gastrointestinal stimulation devices including a random stimulation delivery mechanism(s), configured to provide stimuli to a bodily tissue in a vicinity of the stimulation capsule, the provided random stimuli being characterized by a stimulation parameter, and a control circuitry in communication with said physical stimulation delivery mechanism, and configured to set and alter the stimulation parameter non-systematically, thereby altering the characterization of the stimuli provided to the bodily tissue. The algorithm may be patient tailored, and may have a learning machinery which responds to data being received from the patient.
