A therapeutic hand exerciser includes a resilient core and a fabric exterior lining. The core is soft, pliable and smooth when squeezed. The soft smooth feel of a segmented polyurethane fabric, such as LYCRA.RTM., also provides a more pleasurable feel than a rubber cover. The addition of the thermo plastic urethane (TPU) lining prevents the core material from passing through the fabric cover.

Hand, knee and elbow orthosis each have a deformable semi-rigid stiffener having two end plates joined by a narrow midportion and contained between thin foam sheets to make an insert. A launderable cover of terry cloth fabric with permanently attached straps and a zippered opening fully envelops the insert. The hand orthosis has symmetrical left and right thumb extenders for ambidextrous application. The elbow and knee orthosis are symmetrical in length and width for convenient application insen...

A deformable member can be used in a well tool for use in downhole oil/gas wells. In one embodiment, a deformable member is described which is deformable between undeformed and deformed positions, and comprises a generally hollow cylindrical body defining a wall. The wall includes three circumferential lines of weakness in the form of grooves, with two grooves provided in an outer surface of the member wall and the other groove provided in an inner surface. The member is deformed outwardly by fo...

A deformable mirror includes a deformable section in which, a reflecting surface is formed, a fixing section which fixes an outer periphery of the deformable section, a GND electrode which is formed on the deformable section, a drive electrode which is provided facing the GND electrode, and a driving-signal source which deforms the deformable section by an electric voltage applied between the GND electrode and the drive electrode. The deformable mirror is sealed such that a pressure inside to be...

This invention relates to a hybrid deformable mirror. A deformable mirror is provided comprising a reflective surface provided on a substrate and a layer of deformable material attached to the substrate that is operable to deform the mirror and wherein the substrate is supported by an actuator that is operable to deform the mirror.

A thin reflecting disk tightly bears on one edge of a case for defining a closed volume, means being provided in the latter for producing a negative pressure, and the bottom of the case is provided with supports arranged in parallel rows of three supoprts, a small beam being advantageously interposed between the disk and each row of supports when this mirror is used for focusing a laser beam, it is possible, by simply regulating the supports, to modify the shape of the disk so as to, e.g. obtain...

A deformable mirror, especially for the compensation of the influences of atmospheric interferences on the propagation or spreading of high energy laser beams, which incorporates a plurality of electrically actuatable actuators or adjusting elements engaging behind the mirror surface of the mirror. The actuators or adjusting elements is pressed against the rear side of a mirror plate, and is connected therewith along jacket or sheathing surfaces. Thereby, it is possible to achieve an almost poin...

Deformable wall which is manufactured preferably from reinforced plastic includes least one closed cavity (2) and is arranged in the interior of the wall (1). A device (6) to change the cavity pressure is provided. The cavity pressure is decreased or increased to deform the wall (1).

Hand, knee and elbow orthosis each have a deformable semi-rigid stiffener having two end plates joined by a narrow midportion and contained between thin foam sheets to make an insert. A launderable cover of terry cloth fabric with permanently attached straps and a zippered opening fully envelops the insert. The hand orthosis has symmetrical left and right thumb supports for ambidextrous application. A finger separator may be attached and adjustably positioned on the hand orthosis. The elbow and ...

The present invention relates to an improved deformable splint which is adapted for engagement with the hand of a user. In its broadest context, the present invention includes a wire which is surrounded by a cover of resilient material. As such, the splint can be deformed into any number of various shapes to enable it to be employed upon the hand of the user in a number of different configurations. The splint further includes a number of VELCRO.TM. straps which are employed in securing the splin...
