    Abstract: A gripping device is equipped with an abutment member that is annexed on a region of a gripping portion that abuts on a work. The abutment member is equipped with an inner bag that is made of a material having elasticity, a particulate matter with which the inner bag is filled, and an outer bag that covers the inner bag. The particulate matter is hardened while being deformed into a shape matching a contour of the work by increasing a ratio of a volume of the particulate matter to an inner volume of the inner bag with the work gripped by the gripping portion. A reverse face of the outer bag and a surface of the inner bag have a light-emitting portion therebetween. Thus, a rupture created in the outer bag can be detected, and the breakage of the inner bag can be obviated.

  • Patent number: 9314933
    Abstract: A robot having an overall structure inspired by the Octopus vulgaris is described. The robot has soft arms joined in a radial manner to a central support. The soft arms have the capability of lengthening, shortening and wrapping around in a coil-shape manner. The extremely simple movements and coordination of the soft arms are effective because of the interaction between the single actions. For example during locomotion, while some arms act as a support for stability, the others provide for thrusting allowing the robot to advance. Once near the target, some arms provide for stability whereas the others can bend so as to wrap around and transport external entities.

    Abstract: A method for easing child birth and, more particularly, to a device for practicing the method for easing child birth and, most particularly, to a device for easing child birth controlled by the individual giving birth to the child. The device mechanically replaces a “manual” contact, which can be applied to the pelvis of a woman in labor, for the purpose of aiding the expulsion of the baby, and reduce the pain and discomfort associated with this process. The device mechanically compresses the ilium portion of the pelvis medially and posteriorly, simultaneously. The pressure applied by the device is under full control of the patient, so that pressure is applied slowly and progressively to a point of maximum comfort. The pressure is decreased immediately upon demand by the patient. The duration of the application of compression corresponds with the length of the contraction period for the woman.

The medical instrument may also includes a movable plate which is pressed against the support member when the bladder is inflated to secure the instrument to the support member. The medical instrument may further include a bulb located adjacent to the instrument handle that is squeezed to pump air into the bladder to cause it to expand against or constrict around the support member to secure the instrument to the support member.

  • Patent number: 6179357
    Abstract: This apparatus is a tongs-like, load-lifting device for automatically loading and unloading objects and liquids, comprising two elongated numbers pivoted at a selected distance from the apparatus' top with a main pivot pin. Its lower portions are essentially vertical, and may have perforations, to hold in place either a retrieved object or liquids, when pivoted, hemispheric buckets are included. Two hammerheads, mounted at ends of horizontal bars, located on apparatus' upper portions, are provided with magnets to either attract or repel each other. One head may have an electromagnet and the other a permanent magnet, or both heads may have electromagnets. The bottoms of apparatus' lower portions have pivoted extensions to help support the load. The two extensions are held up by either springs or stretchable bands, so their ends would not injure a person. The extensions are pushed down by the person or the object entering the apparatus.
