Methods are provided for controlling a powered lower limb device. A stance phase control method is disclosed in which the required joint torque is determined based on the difference between two joint angles, such as the knee joint and the ankle joint. A swing control method is also disclosed that employs feedback-based minimum jerk trajectory control. A joint assembly for use in a modular lower limb device is also provided. The joint assembly includes a reconfigurable slider-crank mechanism that is configurable to provide a plurality of different ranges of rotational travel, rotational speeds, and torques, for customization according to different anatomical joints. The joint assembly may include a compact coupling device for coupling a ball screw of the slider-crank mechanism to an output shaft of a motor. When employed to form a modular orthosis, the joint assembly may be adapted for self-alignment as its length adjustment method during setup.

Systems and methods for treating Peyronie's disease, including systems for generating acoustic shock waves within an enclosed negative pressure chamber to fragment or otherwise modify plaque in a patient's penile shaft.

A method of operating a modular exoskeleton system, the method comprising: monitoring for one or more actuator units being operably coupled to or removed from the modular exoskeleton system, the modular exoskeleton system comprising at least a first actuator unit configured to be operably coupled and removed from the modular exoskeleton system; determining that the first actuator unit has been operably coupled to the modular exoskeleton system; determining the first actuator unit has been associated with a first body portion of the user; determining a first new operating configuration based at least in part on the determination that the first actuator unit has been operably coupled to the modular exoskeleton system and the determination that the first actuator unit has been associated with the first body portion of the user; and setting the first new operating configuration for the modular exoskeleton system.

An exoskeleton system comprising: a power system that powers the exoskeleton system, the power system including one or more battery slots, and a modular battery set that includes one or more battery units that are modular such that any of the one or more battery units can be readily and quickly removed and coupled within any of the one or more battery slots to provide power to the exoskeleton system.

A system for controlling blood pressure includes a wearable interface having an internal contact surface, the wearable interface configured to at least partially encircle a first portion of a first limb of a subject, a sensing module carried by the wearable interface and configured to determine at least a change in blood pressure of the first limb of the subject, and an energy application module carried by the wearable interface and configured to apply energy of two or more types to the first limb of the subject.

A computer implemented method of semi-supervised intent recognition for an exoskeleton system. In one aspect, the method includes, in response to a state transition intention input, changing the exoskeleton system from operating in a first mode with sensitivity to detecting state transitions at a first sensitivity level to operating in a second mode with sensitivity to detecting state transitions at a second sensitivity level that is more sensitive than the first sensitivity level; identifying a state transition while operating in the second mode and using the second sensitivity level; and facilitating the identified state transition by actuating the exoskeleton system.

A sexual stimulation device includes a housing, a suction nozzle, a motor, an eccentric rod, and a connecting rod. The motor drives the eccentric rod to rotate. The eccentric rod drives the connecting rod to swing left and right to enable a stimulation member to swing left and right. The stimulation member swings left and right to squeeze the air in a space in the suction nozzle to generate an air vortex. The force generated by the air vortex is to perform 360° massage and stimulation on the female erogenous zone. It effectively enhances the user's experience, and it is easier for the user to have an orgasm.

A health-regain device includes a driving portion, a health portion disposed on one side of the driving portion, and a control module communicably connected to the driving portion, wherein the control module controls the driving portion driving the health portion in rhythmic reciprocating motion.

A time saving sit on cardio pulmonary resuscitation device and method wherein the said device for providing cpr is adopted with an arrangement to seat a person and enable the start of cpr within five minutes of a heart attack affecting a patient, comprising of a reciprocating resuscitation force applicator where a counter force to the reactive force arising on applying compression force for resuscitation, said counter force being provided by the weight of a person sitting on the seating means and a belt based drive conveyance means forming a loop from top of a enclosure box allowing cpr without latching. A very clearly understandable, unambiguous, two step method of sitting on the device placed around the patient body, no confusion, no decision steps, no mental thinking on what to do. The device takes care of most decisions automatically.

An air pump device for a massage device includes a recognition device to acquire a type of the massage device via a wireless communication with an identification device of the massage device, and a controller to set an operation pattern based on the type of the massage device. The controller controls a pump connectable to an inflatable bladder of the massage device, based on the operation pattern.
