Abstract: A system for near-surface geophysical subsurface imaging for detecting and characterizing subsurface heterogeneities comprises an instrument that outputs probing electromagnetic signals through a ground surface that interact and are affected by scattered signals of acoustic waves that travel through the ground surface and further senses vibrational modes of a subsurface below the ground surface; an imaging device that dynamically generates a time sequence of images of properties of the acoustic waves and maps elastic wave fields of the acoustic waves; and a processor that analyzes dynamic multi-wave data of the images to quantify spatial variations in the mechanical and viscoelastic properties of the subsurface.

Abstract: An oil drain receptacle attachment, integrated system and method of use for providing a closed, clean catch system for the requisition of used motor oil for recycling. The oil drain attachment itself is positioned between a flexible drain tube and a collection receptacle where the reversibly attachable oil drain attachment allows for securing of the flexible tubing to an opening of the receptacle, in operation, that is capable of initiating and ceasing flow, through an ‘on’ and ‘off’ functionality, in addition to intermediate, partial opening and closing positions, as well as providing ventilation that facilitates the exit of air with the introduction of used oil into a collection receptacle for transportation and disposal.

Abstract: An oil change drain valve includes a hollow valve body and a hollow body valve actuator arranged coaxial with the valve body. The valve body is adapted for insertion into an oil pan and houses a check ball and a spring arranged to urge the check ball into a closed position. The valve actuator is adapted for temporary insertion into a lower end of the valve body and includes a bayonet at its upper end. As the valve actuator moves toward the check ball, the bayonet contacts the ball and urges it into an open position. Oil flows through the valve body and actuator unimpeded by any mechanical or moving parts.

Abstract: A computer-implemented financial management system provides the trading of securities via a network using virtual currency. A server computer receives buy and sell orders for derivative financial instruments from a plurality of client computers. The server computer attempts to match the buy and sell orders and then generates a market price through the use of a virtual specialist program executed by the server computer. The virtual specialist program responds to an imbalance in the matching of the buy and sell orders. The virtual currency accumulated by HSX account holders as a result of successful trading may be converted to another currency, credited toward the cost of merchandise provided through a vendor's web site, etc.
