Shock absorbers for footwear are provided. The shock absorbers are units utilizing a shock absorbing spring system, and project like cleats from recesses in the soles of footwear. The shock absorbers serve to minimize impact shock in the normal use of footwear. The shock absorbers do this by compressing as weight is applied to the shoe, to the point that the shock absorbers may become flush with the bottom of the shoe's sole on normal impact if desired. When weight is released from the shoe (for...

A device for stimulating the soles of a person's feet comprises a plastic holder having a central recess. A multiplicity of spherical plastic bearings of different sizes are supported within the recess in a loosely-packed layer. A dampening medium such as a gel surrounds the bearings to dampen their movement. A plastic film overlays the bearings and conforms to the shape of the underlying bearings when stepped on by the feet. A user simply stands on the plastic film and rocks thereby displacing ...

A satellite communication system for sending high resolution medically related images from a remote location to a central location for diagnostics, consisting of at least one remote transmitting and receiving station and a central diagnostic station adapted to provide an image based on a standard digital format such as Digital Imaging and Communications in Medicine (DICOM), and the Extended Transmission Control Protocol to transmit medically related images with a transmission efficiency of at le...

An electromagnetic relay is provided with an electromagnet system with a U-shaped core yoke and an essentially flat armature, which form a working air gap on a longitudinal side underneath the coil winding. One yoke limb lies immediately on the coil winding, so that the make motion of the armature is towards the coil. In this way, a relatively large contact room is formed underneath the yoke limb and a movable contact spring extends approximately parallel under the armature. The contact spring i...

An electromagnetic relay includes a winding, a magnetic core disposed within the winding, and an armature mounted for movement at a first end of the winding. At least one movable circuit contact is operably associated with the armature and movable with respect to at least one stationary contact mounted in the relay responsive to motion of the armature. An end plate is mounted at an opposing end of the winding and an insulating sheet is folded about a portion of the winding. The insulating sheet ...

This invention provides a simple and inexpensive vibrator. Upper and lower linked arms are used to hold equal weights attached at the ends of the arms. The arms are attached to collars which spin. A bent axle is used to cause displacement of the upper collar with a resultant shortening of the effective radius of rotation of one of the weights at a determined position in the circle of rotation. This shortening of the effective radius of rotation imparts a vibratory motion to the vibrator.

An arc welding process for welding a circumferential surface of a fixed pipe etc. by shielding a work part with a shield gas is provided. It is welded by a flat arc formed in a flat sectional view by simultaneously ejecting a gas from nozzles (19) to the arc formed between a welding torch (10) and a product for welding by placing a pair of the gas nozzle (19) for ejecting the gas at the end of the welding torch (10).

The vibration device according to the invention includes a compensating device influenced by compensating masses for exciting forces caused by the vibrationary movement, the compensating masses respectively being arranged as partial masses on a hollow shaft, being coaxial with respect to one another, and including a displacing rod in their center by means of which the partial masses of the compensating weights can be displaced in the same manner as the eccentric determining the vibrational movem...

The present invention relates to a method of performing surgery on a spinal column utilizing a posterior spinal system including components designed to be affixed to the spinal column of a person to correct for various lateral and sagittal deformities. The method includes the use of a pair of smooth surfaced rods mounted in spaced relation to one another on the spinal column in conjunction with various fixation devices such as clamps with hook bodies, hooks, screws with hook bodies and couplers....

A data logging system and method in which an implantable medical device transmits logged data to an external data logging device with low energy potential signals. The implantable device generates potential signals modulated with digitally encoded data by operating a current source to cause corresponding electrical potentials that can be sensed at the skin surface by the external data logging device. The data logging device then demodulates the sensed potentials to derive the digital data and st...
