A suction cup device includes a cup forming unit cooperating with a flat surface to create a volume-variable space, a liftable rod secured to a central portion of the cup forming unit, a bracing shell member having a force-transmitting surrounding wall in engagement with a peripheral portion of the cup forming unit, and a twistable cap member having a surrounding bottom wall in abutting against a circumferential abutment region of the bracing shell member and threadedly engaged with the liftable rod such that a manually twisted movement of the twistable cap member can result in axial movement of the rod so as to pull the central portion away from the flat surface to produce a reduced pressure in the volume-variable space and a biasing force to thereby ensuring fluid-tight engagement of the cup forming unit with the flat surface.

The invention is an improved yo-yo that features two side assemblies that sandwich a center axle onto which the yo-yo's tether may be secured. According to a first embodiment, each of the side assemblies preferably includes a releasable, disk-shaped rim piece. By replacing one set of replaceable rim pieces with another, a user can quickly and easily change the yo-yo's shape, look and / or functionality. To remove a rim piece, one first removes a lock ring that is secured to the rim piece and blocks a number of openings that lead to grooves in a center-located hub. Next, one employs a twisting movement of the rim piece to cause a number of tabs attached to the rim piece to slide in the hub's grooves until the tabs are aligned with the openings. The rim piece can then be disengaged from the yo-yo.

An exercise cycle and a method of using the exercise cycle, in which motion from the user's twisting of the torso and alternate pushing on hand grips are transmitted to the driving shaft for movement of the cycle. The exercise cycle comprises a frame, a front wheel, a first rear wheel, a second rear wheel, a seat, operator handles, hand grips, foot force plates, and a driving device. The driving device consists of a driving shaft, a force plate, pivotal arms, an elongate member, and a disk. The input of the user by torso twisting movement or pushing on handgrips will cause the cycle to move forward or backward.

The invention discloses a three-dimensional human body evaluation template, which comprises forward and backward swinging dials, inward and outward swinging dials, twisting movement dials, inward and outward wrist joint flexion movement dials, upward and downward ankle joint movement dials, elbow joint dials and forward and backward knee joint swinging dials, wherein the forward and backward swinging dials and the inward and outward swinging dials are arranged at shoulder joints and hip joints; the twisting movement dials and the inward and outward wrist joint flexion movement dials are arranged at wrist joints; the twisting movement dials and the upward and downward ankle joint movement dials are arranged at ankle joints; the elbow joint dials are arranged at elbow joints; and the forward and backward knee joint dials are arranged at knee joints. According to the template, angle measurement devices are arranged at human body joints, and are linked through pointers to read movement angles of the joints, and non-movement areas, practicable movement areas and comfortable movement areas of the dials are distinguished through red, yellow and green according to a human engineering standard, so that operating comfort can be directly identified, position evaluation and human body evaluation characteristics are combined, and the template is simple and convenient.

An exoskeleton structure includes a pelvis assembly, a first lower limb assembly, a second lower limb assembly and a back assembly. The exoskeleton structure includes pivot joints connecting each of the lower limb assemblies and the back assembly to the pelvis assembly and permitting movements of abduction or adduction of the lower limbs of the user, a relative movement of lateral inclination of the spine of the user with respect to the pelvis of the user, and a twisting movement of the spine.

The embodiment of the invention discloses a device for measuring conduit interventional force and torque in a cardiovascular interventional operation in real time. The device comprises an outer support, an inner shaft, force sensors, bolts and nylon fasteners, wherein each force sensor is adhered to the inner circumference of the outer support; the inner shaft is placed in the outer support with the force sensors; the outer wall of the inner shaft is in interference contact with each steel ball of each force sensor; male end and female end nylon fasteners suitable for winding a thumb or a forefinger are cut; holes are formed in at the bottom ends of the male end and female end nylon fasteners in a cutting way to enable the bolts to pass through; the bolts pass through a female end thread gluing, an inner shaft screw hole and a male end thread gluing and are screwed by using nuts; and the nylon fasteners are used to adapt to the sizes of different fingers of operators, so that the operator wears the device to clamp a conduit in the operation to ensure that the conduit does translation or twisting movement. By using the device, stress information in an operation process can be monitored, and the safety of the operation is improved; and by acquiring the operating force and the operating torque of an experienced physician, the device provides quantitative evaluation standards for a virtual training system of the cardiovascular interventional operation at the same time.

The invention discloses an implementation method of a virtual hula hoop based on an accelerometer. The implementation method comprises the following steps: acquiring acceleration data of movement of the hula hoop as training samples, carrying out filtering treatment on the training samples by adopting a kalman filter, and carrying out classification algorithm treatment by adopting a naive bayes classifier. When people doing exercise make waist twisting movements by wearing the virtual hula hoop on the waist, through the classification algorithm, whether the waist twisting strength and amplitude of the people achieve the movement level of the real hula hoop or not is judged, if so, the one circle of movement of the virtual hula hoop is recorded, and finally, the movement result is sent to a mobile phone terminal through Bluetooth equipment so that a user can conveniently check the result.
