A continuously variable speed controller comprises an operating unit, an operation detector coupled to the operating unit to detect a continuous variation of an action of the operating unit, an information processor electrically connected to the operation detector to obtain a corresponding motor speed variation quantity based on a detection result from the operation detector, and a motor controller electrically connected to the information processor to receive the motor speed variation quantity and adjust a speed of the motor continuously based on the motor speed variation quantity. As such, speed control becomes more intuitive, and can achieve stepless speed change, while no need to set the speed switch to occupy the control and detection ports, simplifying structure of the product.

A remotely controlled powered chair may include a support frame, a seat pivotally mounted on the support frame, an rotary actuator mounted between the support frame and the seat to drive the seat to move relative to the support frame, a backrest pivotally mounted on the seat, and a linear actuator mounted between the seat and the backrest to drive the backrest to move relative to the seat. Thus, the rotary actuator may be controlled by an electrically control device to drive the seat to pivot relative to the support frame reciprocally in a pendulum manner so that the seat is pivoted relative to the support frame automatically. In addition, the linear actuator may be controlled by the electrically control device to adjust the inclined angle of the backrest so as to provide a comfortable sensation to the user. A remotely controlled powered chair may include a base assembly. A chair frame is supported on the base assembly. An actuator mechanism may communicate with the base assembly and the chair frame, and is operable to actuate the chair frame between first and second positions.

Apparatuses and methods utilizing tactile transducers to create mechanical waves that travel through an individual's body to the kidneys to dislodge kidney stones. Embodiments include a structural member with at least one tactile transducer, an amplifier, and a controller. The tactile transducer(s) produce mechanical waves, and the structural member enables projection of the mechanical waves produced by the tactile transducer(s) toward at least one kidney to dislodge kidney stones. The amplifier is electronically coupled to the at least one tactile transducer, and the controller is electronically coupled to the amplifier and configured to determine the mechanical waves produced by the at least one tactile transducer.

This disclosure relates to device for providing continuous negative abdominal pressure (CNAP) which selectively recruits (inflates) the dorsal (spinal region) collapsed areas of the lung, while enabling the patient to remain in the supine (usual) position. The CNAP device includes a rigid frame configured to have a shape and size to envelop a patient's lower chest and abdominal area while in a supine position with the frame having opposed edges which sit on a surface on which the supine patient is resting. A series of panels are mounted in the frame such that the series of panels extend around the patient's lower chest and abdominal area. A flexible sheet wrapped around the outside of the panels and is long enough to extend up to the patient's upper chest and down to the patient's thighs and wide enough to envelop the supine patient's lower chest and abdominal area. Sealing members are to seal the flexible sheet over the frame and panels and around the patient's lower chest and pelvis, wherein a chamber is formed between the patient and said device when the patient is enveloped by the device. An air inlet coupling extends through one of the panels and is attachable to a suction source which is configured to generate negative pressure of between about −5 to about −10 cm H.sub.2O inside the chamber.

The invention relates to a motorized walker (1) comprising a frame (10) having a front portion (10a) and a rear portion (10b), a pair of wheels (11), with one wheel arranged to support the front portion of the frame, one of the wheels being coupled to a traveling motor (20), said motorized walker (1) being characterized in that: the frame (10) is equipped with two verticalization ramps (100) having a longitudinal axis forming an angle with an axis perpendicular to the ground, between 20° and 40°, each being associated with an electronic handle (200) movable in translation, it comprises at least one verticalization motor (30) arranged to allow movement of the electronic handles (200), and at least one of the electronic handles (200) comprises one or more sensors coupled to a control module (40) configured to control the verticalization motor (30) and the traveling motor (20).

The present disclosure provides a finger joint rehabilitation training device, which includes a control member, a data acquisition member, a gas circuit system, and a wearable training member. The wearable training member is provided with a pneumatic component that can expand and contract. The data acquisition member is configured for acquiring hand motion information of a first hand and transmitting the hand motion information to the control member. The hand motion information includes hand pressing information. The control member controls the gas circuit system to inflate the pneumatic component or to draw air from the pneumatic component according to the hand motion information, to make the wearable training member change between a flexion condition and a stretching condition, so as to realize a hand mirror training of a second hand. The hand pressing information is simple and convenient to acquire, which is convenient for the first hand to realize the flexion condition and the stretching condition, and the condition of the second hand is adjusted through the condition of the first hand, so that the wearable training member can be better adjusted, different hand training intensity requirements are met, and a better training effect is achieved.
