A patient support for supporting a patient includes an inflatable mattress defining a support surface and a pneumatic system for inflating the inflatable mattress. The pneumatic system includes a pressurized reservoir for holding pressurized air and selectively releases pressurized air from the reservoir to the mattress.

In some embodiments, a system and/or method may include an inner wearable harness worn, during use, on a torso of a subject which includes a flexible vest. The system may include a plurality of engines, each of which are contained in a flexible container, which when activated apply an oscillation force. The system may include a positioning system which allows positioning the flexible container such that the oscillation force is applied to at least one treatment area of the subject. The oscillation force may mobilize, during use, at least some secretions in an airway within the subject substantially adjacent the treatment area. The system may include an outer harness worn, during use, on a torso of a subject. The outer wearable harness, when activated, adjusts the oscillation force applied by at least some of the activated plurality of engines to the treatment area by providing a compressive force.

Devices and methods for assisting and guiding a person with visual and/or hearing impairment. In various embodiments there is a computer-guided, motorized walking stick. Preferably, at least one wheel at the distal end of the stick, and in contact with the ground, can be steered or pivoted over a range of angles, and thus establish a desired direction. In yet other embodiments there are one or more powered wheels that further drive the walking stick in the desired direction. Various algorithms are disclosed for providing instructions to the computer controller by way of various input devices. Still further embodiments include various types of sensors that provide data to the computer with regards to objects proximate to the walking stick.

An assist system includes a fist belt worn on an upper body part of a user, a second belt worn on a knee of the user, a wire, a motor coupled with a first end of the wire and disposed on the first or second belt, a drive controller that controls drive of the motor, a gyro sensor that is disposed on the second belt and that measures an angular velocity about a direction perpendicular to the direction of the wire, and a controller. When the angular velocity is greater than or equal to a first threshold with a first tension being applied to the wire using the motor, the controller outputs first information. A second end of the wire is coupled with the second belt when the motor is disposed on the first belt but coupled with the first belt when the motor is disposed on the second belt.

A skin cleanser includes a surface, such as a silicone surface, with at least one textured portion for transmitting vibrational tapping to the skin. The skin cleanser includes at least one oscillating motor fist generating the tapping motion to the skin. The textured portion includes touch-points or a wave that transmit the tapping motion to skin in contact with the textured portions. The touch-points may include thicker and thinner formations of the touch-points to provide firmer or stiller vibrations to the skin. The touch-points are within about 0.5 to 2.5 nun in diameter. One configuration includes multiple oscillating motors configured to provide different vibration frequencies at around 50-300 Hertz and operable simultaneously.

Described here are devices, systems, and methods for treating one or more conditions (such as dry eye) or improving ocular health by providing stimulation to nasal or sinus tissue. Generally, the devices may be handheld or implantable. In some variations, the handheld devices may have a stimulator body and a stimulator probe having one or more nasal insertion prongs. When the devices and systems are used to treat dry eye, nasal or sinus tissue may be stimulated to increase tear production, reduce the symptoms of dry eye, and/or improve ocular surface health.

A skin cleanser includes a surface, such as a silicone surface, with at least one textured portion for transmitting vibrational tapping to the skin. The skin cleanser includes at least one oscillating motor for generating the tapping motion to the skin. The textured portion includes touch-points or a wave that transmit the tapping motion to skin in contact with the textured portions. The touch-points may include thicker and thinner formations of the touch-points to provide firmer or softer vibrations to the skin. The touch-points are within about 0.5 to 2.5 mm in diameter. One configuration includes multiple oscillating motors configured to provide different vibration frequencies at around 50-300 Hertz and operable simultaneously.

In some embodiments, a system may include an inner wearable harness including a flexible vest. The system may include at least one engine which when activated apply an oscillation force. The at least one engine is positioned after the vest has been positioned on the subject on different areas of the inner wearable harness to allow selective placement of engines on and/or adjacent areas of the subject's chest such that the oscillation force is applied to at least one treatment area. The oscillation force may mobilize, during use, at least some secretions in an airway within the subject substantially adjacent the treatment area. The system may include a flexible and elastic outer harness worn, during use, on a torso of a subject which when activated provides a compressive force to adjust the oscillation force applied by at least some of the at least one engine to the treatment area.

A method for providing electrical current treatment by an apparatus having a first electrode, a second electrode, and a processor is provided. The method includes delivering an electric current through an object in contact with the first electrode and the second electrode; controlling, by the processor, the electric current delivered by the first electrode and the second electrode to have a specific waveform; and providing a notification at a predetermined time to notify a user to move the apparatus.

Provide is an air massage device including a plurality of air bags; an air pump 31 for supplying air into each of the air bags; solenoid valves 32 for switching on-off of air supply into each of the air bags; and a control part for changing an electric input value into the air pump 31 and an amount of the supplied air into each of the air bags per unit time to open and close each of the solenoid valves 32 so as to correspond to this change of the amount of the supplied air.
