Abstract: A method of characterizing a subterranean formation using a plurality of seismic acquisitions includes obtaining a first seismic acquisition of the subterranean formation, wherein the first seismic acquisition is a baseline survey. Injecting a gas fluid into the subterranean formation, wherein the gas fluid at least partially fills a portion of a fracture network of the subterranean formation. Obtaining a second seismic acquisition of the subterranean formation. Calculating a time-lapse difference in the plurality of seismic acquisitions.

Abstract: A remote control system (10) for a locomotive (16) includes a sensor (e.g. 15) on-board the locomotive for providing locomotive information. The system also includes a transmitter (13) for transmitting the locomotive information from the locomotive to an operator control unit (OCU) (12) off-board the locomotive. A graphical display (24) is associated with the OCU for displaying the locomotive information in a graphical format to an operator of the OCU. A locomotive control unit (LCU) (14) in communication with the OCU is operable to control the locomotive in response to a manipulation of the OCU by the operator.

Abstract: A method and system for providing advertisement services to a user of pre-paid telephony services includes communicating a PIN via a telephone link to a voice response unit, using a PIN-based index of pre-recorded services to generate a valid access request and matching the PIN link to an existing pre-recorded audio service. The person accessing the voice response unit can control telephonic access to the server or merchant who is offering the service or advertisement via telephone keypad instructions transmitted to the voice response unit and passed on to the data management server. The pre-recorded audio services may be, e.g., stored on a server as digital audio source, several control data fields including the PIN range associated with that message, a field for a dial-to number to the Audio Services Provider/Owner and fields to contain accounting numbers.

Abstract: A portable solar module cart is provided which comprises a platform, a pair of wheels attached to opposite sides of the platform, a pair of support struts attached to opposite sides of the platform and movable relative to the platform between a first retracted position in which they lie substantially parallel to the platform and a second erected position in which they extend at a selected angle to the platform so that a DC power source can be disposed on and supported by the platform, a solar panel pivotally mounted to the struts, the solar panel being movable on its pivot when the struts are in their erected position so as to be in a perpendicular relationship with an imaginary line connecting the sun and the solar panel, whereby to maximize the solar energy collected by the panel, and means for locking the solar panel in any selected position on its pivot.

Abstract: A one-piece table base of molded plastic includes at least three hollow upright legs extending outwardly from each other from a central portion. Each leg has at least one side wall. Each side wall has first and second wall portions which are offset from each other and joined together by a first upwardly arching ridge. An upper flange extends from upper portions of the legs for attachment to a table top.

Abstract: A rotatable seat with a sealed rotating member for use in a prison.
