Abstract:
Determining whether a compression garment is worn by a wearer of the garment by analyzing a pressure signal waveform indicative of a fluid pressure in an inflatable and deflatable bladder of the compression garment. Variance detected in the pressure signal waveform during the analysis is indicative of a change in condition of the compression garment. In one aspect the change in condition is verified using confirmatory analysis. In another aspect, the variance is one of a pressure rise and a pressure impulse. In yet another aspect, the variance is an oscillating amplitude as a function of time representative of a pulse of the wearer.
Abstract:
An exoskeleton for applying force to at least one lower limb of a user includes a control system with a sensor interface for sensor signals; a power interface for transmitting control signals to the powered joint; a processor coupled to the sensor and the power interfaces; and a computer-readable medium storing a computer program executable on the processor with code sections for: estimating a configuration of a body of the user with respect to a gravity vector based on the sensor signals; computing a control torque for the powered joint that compensates gravitational dynamics of the user based on the configuration; calculating a gravitational energy gradient for the powered joint; attenuating the control torque based on the gravitational energy gradient; computing a final control torque based on the attenuated control torque, and configuring the control signals based on the attenuated control torque.
Abstract:
Many devices with “limbs” or “arms” are susceptible to damage when a user bends or twists a joint of the limb or arm beyond its design point or in a direction other than intended. This is common with children's toys. Accordingly, it would be beneficial to provide children with toys employing fluidic actuators that can be bent, twisted, deformed and yet recover subsequently allowing the intended motion to be performed. Further, it would be beneficial by providing devices that employ fluidic actuators, and hence are essentially non-mechanical, to provide users not only of toys but other devices with driving mechanisms that are not susceptible to wear-out such as, by stripping drive gears, etc., thereby increasing their reliability and reducing noise. Fluidic devices allow for high efficiency, high power to size ratio, low cost, limited or single moving part(s) and allow for mechanical springless designs as well as functional reduction by providing a piston which is both pump and vibrator.
Abstract:
In some embodiments, a kit may include systems allowing for clearing a biological airway. The kit may include an inner wearable system worn, during use, on a torso of a subject. The kit may include a plurality of engines which when activated apply an oscillation force to at least one treatment area of the subject. At least one of the plurality of engines may be releasably couplable to the inner wearable system. The oscillation force may be applied to at least one of the treatment areas of the subject such that the oscillation force mobilizes, during use, at least some secretions in an airway within the subject at least adjacent the treatment area. The kit may include an outer wearable system worn, during use, on a torso of a subject which when activated, adjusts the oscillation force. The kit may include one or more batteries and/or a control unit.
Abstract:
An adjustable foundation includes a base frame and an articulating frame movably supported by the base frame for longitudinal movement with respect to the base frame. A mattress platform is positioned on the articulating frame. A concealing assembly is positioned below the mattress platform and at least partially conceals the base frame. The concealing assembly is attached to the articulating frame for simultaneous longitudinal movement therewith.
Abstract:
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.
Abstract:
A device for use by an individual for sexual pleasure varying in form, i.e. shape, during its use and allowing for the user to select multiple variations of form either discretely or in combination and for these dynamic variations to be controllable simultaneously and interchangeably while being transparent to the normal use of the device, including the ability to insert, withdraw, rotate, and actuate the variable features manually or remotely. According to embodiments of the invention localized and global variations of devices are implemented using fluidics and electromagnetic pumps/valves wherein a fluid is employed such that controlling the pressure of the fluid results in the movement of an element within the device or the expansion/contraction of an element within the device.
Abstract:
Airbags each belonging to one of first and second control blocks are arranged below the thighs of an occupant seated on a seat seating surface (S). Specifically, the first and second control blocks are arranged such that the airbags belonging thereto are adjacent to one another in the seat width direction. Further, a seat device controls the airbags belonging to the first control block and the airbags belonging to the second control block to alternately expand and contract.
Abstract:
According to one aspect of the disclosure, a massage device for a vehicle seat is provided. The message device includes a linear series of inflatable massage cells which are to be arranged in succession below a cover of a backrest or a seat body of the vehicle seat, supply and venting lines to and from the massage cells. A compressed air pump is connected to the supply inventing lines. A valve arrangement is provided for the selective supply of massage cells with compressed air and for the selective venting of massage cells. A control unit is provided for controlling the compressed air pump and the valve arrangement, said control unit being arranged for carrying out massage functions by controlling the compressed air pump and the valve arrangement according to a predetermined sequence set individually by the user for the selective inflation and venting of massage cells in the linear series.
Abstract:
A support system includes a support frame and at least one modular leg assembly mounted to and supporting the support frame. The leg assembly includes a first leg member and a second leg member. The second leg member has a top-to-bottom length that is greater than the top-to-bottom length of the first leg member. The first and second leg members are connected individually or in combination to the support frame such that at least three leg heights are selectably provided. The leg members may each have a threaded connecting element extending therefrom for connecting the leg member to another leg member or to the support frame. The support system may be a mattress support frame. The at least one modular leg assembly may be a plurality of modular leg assemblies.
