Exemplary arrangements provide leg training devices suitable for high intensity training of hip flexors while simultaneously training the extensors of hip and knee joints. The exemplary leg training devices include foot fixings which are permanent vertically movable components of the device, each of which are configured to releasably engage a foot of a user in operative engagement therewith while limiting the movement of the foot relative to the foot fixings. Each of the foot fixings is operatively connected to a suitable mechanism that provides a resistance force to vertical movement of the foot fixing by the user's leg. In exemplary arrangements the resistance force may be selectively variable with regard to the magnitude and/or point of application so as to provide the desired training regimen.

A method for cardiopulmonary resuscitation (CPR) includes supplying an inflation gas at an operative pressure to an inflation actuated soft gripper device to change form from an undeployed state to a deployed grip state that accommodates and grips a human torso. The inflation actuated soft gripper device includes a first inflatable gripper arm having a first distal end and a second inflatable gripper arm having a second distal end. The first distal end and the second distal end approach one another from the undeployed state to the deployed grip state. The first and second distal ends are spaced apart from one another further in the undeployed state than in the deployed grip state. An actuator power and a CPR control signal are delivered to a CPR pressure application device to cyclically extend and retract a pressure applicator along an axis in alignment with a sternum of the human torso.

A sexual stimulation apparatus comprising a main body enclosing an internal motor, a first handle coupled to the main body, and is detachably coupled to a second handle, and a thrusting pole coupled longitudinally at one end to the main body and at other end to a phallic device attachment rod via an attachment point, wherein the thrusting pole is forced to move longitudinally with respect to the main body, towards the attachment point and thereby provides thrust to the phallic device attachment rod.

A system and method for controlling sexual stimulation devices using motion-sensing controllers. The system comprises a male sexual stimulation device and a motion sensing controller configured to control the operation of the reciprocating linear motion driver. In operation, natural motions of a user with the motion sensing controller result in corresponding motions of the male sexual stimulation device such as reciprocal linear motions and rotational motions.

An improvement to portable cardiopulmonary resuscitation (CPR), includes a first module hub housing, an inflation actuated soft gripper configured to receive an inflation gas in response, to change form to a deployed grip state that accommodates and grips a human torso. Improvements include the inflatable gripper not requiring lifting the patient. Improvements also include modularity for in-the-field reconfigurability, in which a second module hub housing attaches to the first module hub housing, carrying a CPR pressure applicator configured to receive an actuator power and control signal causing, concurrent with the deployed grip state, cyclic extension and retraction of a pressure applicator along an axis aligned with a sternum of the human torso.

A catheter that fits within a blood vessel wall includes electrodes aligned along a longitudinal axis of the catheter that produce unfocused shock waves that propagate radially toward the blood vessel wall for treatment.

In at least one aspect, there is provided a system for generating force about one or more joints including a soft exosuit having a plurality of anchor elements and at least one connection element disposed between the plurality of anchor elements. The system also includes at least one sensor to determine a force the at least one connection element or at least one of the plurality of anchor elements and to output signals relating to the force, at least one actuator configured to change a tension in the soft exosuit and at least one controller configured to receive the signals output from the at least one sensor and actuate the at least one actuator responsive to the received signals.

Disclosed are a sexual massage apparatus, an engine assembly, and a massage machine. The sexual massage apparatus includes: an engine assembly, including an outer shell and a first driving unit, wherein the outer shell has a hollow cavity defined therein, and the first driving unit is arranged in the hollow cavity; a massage machine, capable of being at least partly inserted into the hollow cavity of the engine assembly and being separated from the engine assembly, wherein the massage machine includes a first sexual stimulation unit, when the massage machine is at least partly inserted into the hollow cavity, the first sexual stimulation unit is controlled by the first driving unit, to apply a first sexual stimulation for a human body part, and the first sexual stimulation is a compression sexual stimulation generated along a radial direction for the human body part.

There is provided a technique by which posture changing can be given to an occupant while the forward shift of his/her hip portion is prevented. A seat for vehicle includes a seat cushion, and a seat back coupled to the seat cushion, and the seat back includes a posture changing mechanism having a back face supporting mechanism. There is provided a technique by which a fatigue reduction operation using the posture changing mechanism includes a) moving the back face supporting mechanism set to a position of a lumbar spine portion of an occupant from a first position state to a rear direction side and setting the back face supporting mechanism to a second position state, and b) thereafter, moving the back face supporting mechanism stepwise to a front direction side from the second position state to the first position state.

A reciprocating linear movement massaging apparatus, having a shell, a massaging assembly provided in the shell, a driving mechanism for driving the massaging assembly to perform reciprocating linear movement axially along the shell, and an electric control device for controlling the driving mechanism; the driving mechanism comprises a stator assembly and a mover assembly, an air gap is provided between the stator assembly and the mover assembly; the stator assembly comprises (an) annular coil(s) provided in the shell, the mover assembly comprises a plurality of magnets provided in the annular coil(s), the plurality of magnets enclose to be an annular magnet; the annular magnet is transmissively connected with the massaging assembly and the massaging assembly is located in an annular space enclosed by the annular magnet, and an open cavity is provided in the massaging assembly for receiving a human part to be massaged.
