Abstract: A system configured to connect users based on shared characteristics is disclosed. Each user has a profile including one or more profile tag matching preferences and at least one profile tag. The location of the system users are monitored, which allows the system to determine when system users are coming into proximity with each other. The system analyzes a user-defined location for the presence of other system users. If other system users are present in the user-defined location, the system compares the user's profile tags and profile tag matching preferences to those of the other system users in the user-defined location to determine if any two or more system users are a match. When the system determines that any two or more system users in a user-defined area are a match, the user is alerted of the match.

Abstract: The present invention relates to an economical, high resolution non-destructive method to remotely image rock mass and subsoil features. More specifically, the invention relates to a method measuring the properties of subsoil structure by first creating at least two boreholes in the area to be examined. At least one electromagnetic radiation transmitter is placed in one borehole and at least one receiver is placed in a second at least one other borehole. The transmitter produces a continuous constant signal of about 100 Hz or greater, which traverses the plane between the transmitter and receiver. After measuring simultaneously both the amplitude and phase of the received electromagnetic signal, the signal information is processed using a linear approximation algorithm. Upon comparison of the processed data, with standard data for nearby geological formations, it is possible to accurately determine both the dielectric constant and the conductivity of the subsoil in the plane.
