Abstract: A low-cost hurricane and earthquake resistant house structure includes a rounded shape external wall constructed of a plurality of circumferentially adjacent wall segments, each secured to an adjacent structural vertical stud secured to the ground via a shock absorber. Each wall segment includes a plurality of blocks located and secured on top of one another. A foundation groove receives at least a portion of a lowest block of each wall segment therein, and spaced from inside foundation walls. An aerodynamic roof is secured to the vertical studs, and a floor is mounted on shock absorbers on the ground and connected to the wall with a flexible material.

Abstract: A feet-propelled water vehicle including a buoyant body having a user-supporting platform attached to a rigid frame secured to a pair of pontoons. A pair of propelling paddles is attached to the rigid frame. Each propelling paddle defines a corresponding effectuating section and a corresponding blade section. The supporting platform defines flexible foot contacting regions for transferring the weight shifting action of an intended user to the effectuating sections of a corresponding propelling paddle. Each effectuating section allows the transformation of the force generated by the foot of the user into a corresponding pivotal movement of the paddle relative to the frame. The blade section attached to the effectuating section allows transformation of the pivotal movement of the paddle into a vehicle propelling force for propelling the vehicle across a body of water.

Abstract: An elongate hollow cylindrical member houses electronic circuitry and has disposed on its surface, on either end, a live electrode and a spaced common electrode. The electronic circuitry includes a difference amplifier, and electromyogram signals detected by the electrodes are applied to opposite polarity inputs of the difference amplifier. As the electromyogram signals are of substantially equal amplitude and phase, the electromyogram signals will be subtracted from each other in the difference amplifier to provide a substantially zero output due to electromyogram signals at the output of the difference amplifier. However, electrocardiograph signals, being of opposite phase, will be added in the difference amplifier so that the output of the difference amplifier is substantially due to only the electrocardiograph signal.

Abstract: The instrument consists of a hollow elongated cylindrical housing having a stimulator circuit and a receptor circuit disposed therein. Stimulator leads are connected to the stimulator circuit and receptor leads are connected to the receptor circuit. The housing includes a display means and a stimulator circuit activator switch. The stimulator leads are connected to stimulator electrodes mounted at a first position on the patient, and the receptor leads are connected to receptor electrodes mounted at a second position on the patient. The first position is spaced from the second position and the first and second positions are disposed along the path of a nerve of the patient. The suspected damaged portion of the nerve is between the first and second positions. The stimulator circuit activator switch is activated so that a stimulator pulse is applied, via the stimulator leads and the stimulator electrodes, to the nerve at the first position.

Abstract: A handle arrangement is disposed at the top end of the support and a base at the bottom end. The handle and the base are spaced from each other by a spacer, and the handle is disconnectably connectable to the spacer at one end while the base is disconnectably connectable to the spacer at the other end. The handle, spacer and base comprise tubular members.

Abstract: A foot receiving member has a spring member detachably attached to the bottom surface thereof. The spring member includes a top, arched, layer and a bottom, arched, layer and a strap disposed between the two arched layers. The arched layers are attached, at their ends, to a corresponding end of the strap in such a manner that the spring member will be automatically disassembled under the influence of an extraordinary lateral force.

Abstract: The invention relates to a sporting and exercising unit which includes a foot receiving member and a spring member attached to and disposed at the bottom of the foot receiving member. The spring member includes a spring-leaf-like portion which forms a closed loop and is shaped to permit backward and forward rocking of the user. The spring member may be oval shaped, circle shaped, or in the shape of a parallelogram. The foot receiving member is adjustable to receive different sizes of feet and legs by having opening flaps extending therealong and openings for receiving laces in the flaps whereby to adjust the sizes of these portions by adjusting the sizes of the openings and to adjustably close the openings.

Abstract: The invention relates to an electronic detection and transmission system known in the art as a money clip. Presently available such money clips are pressure sensitive and transmit initiating signals on detection of a decrease in pressure. Such systems have disadvantages, and the present system overcomes certain of the disadvantages by providing a system wherein detection is accomplished by a light sensitive means such as a phototransistor. In accordance with the invention, the electronic circuitry is contained in a housing having a top surface. The phototransistor is disposed below an opening in the top surface, which is preferably centered on the top surface. When the opening is uncovered, light will enter the opening and fall on the phototransistor to activate the phototransistor. The phototransistor is connected in circuit with a transmitter which will similarly be activated to transmit an initiating signal.
