Abstract: Various systems and methods determine a distance, magnitude, and azimuthal angle describing the location of an anomaly within a geologic formation. For example, a method involves identifying an electrical characteristic (e.g., resistivity or conductivity) at each of several sensors in a measurement- while-drilling (MWD) tool. Based on the electrical characteristic, information identifying a formation property of the anomaly is generated. The information includes at least one magnitude and at least one distance. Information information identifying an azimuthal angle is also generated based upon the electrical characteristic. The azimuthal angle relates a position of the anomalous formation to a position of a first sensor in the MWD tool.

Title: Management and delivery of profile data
Inventor: MICHAEL WALTER F
IPC: H04N7/173
Filed: 2010-02-09
Abstract: Aspects of the invention relate to systems and methods for securely retaining profile data and the use of such data for the targeted delivery of content. In one embodiment, a unique profile that represents the user location and is keyed to profile attributes selected from both a first set of data collected from the user location and the second set of profile data collected from an external source, is generated. The key does not allow a third party to identify the end-user location or a user associated with the end-user location. Electronic content transmitted to end-user locations may be encoded such that it may only be accessed by an authorized user and/or on a specific electronic device at the user location. A graphical user interface may be utilized to allow a third-party to provide selection criteria for determining user locations to receive targeted content. Further aspects of the invention relate to an electronic device configured to present targeted content to a user at a user location.

Inventor: REICHENBACH-KLINKE ROLAND
IPC: E21B33/13
Filed: 2009-11-07
Abstract: A process is proposed for blocking underground formations in the extraction of fossil oil and/or gas, a first step involving introducing water-absorbing particles into liquid-bearing and porous rock formations, said particles being water-swellable, crosslinked and water-insoluble polymers, said particles in the water-bearing rock formation finally preventing liquid flow through the rock layers by water absorption. This process is characterized in that the absorbing particles comprise a superabsorbent polymer with anionic and/or cationic properties and a retarded swelling action. This process, which can also be carried out in saline formation waters, is notable in that the swelling of the superabsorbents used begins no earlier than after five minutes and in that the superabsorbents are obtainable by four proposed process variants and any combination thereof. This process, which does not need a carrier liquid, is notable for its simplicity and especially the controllable retardation of the swelling action under the specific conditions of underground rock formations.

Abstract: The intent of this automated net deployment system (see Drawing 9) for subway trains is to both to mitigate the collision impact to suicide jumpers to be survivable using a trigger net system -- strung between take-up spools on either side of the front of train, mounted on dynamically adjusting air shock absorber struts -- which instantly deploys a catcher net when impacted if the train is in motion, that safely scoops the jumper up, thus protecting them from ricocheting into other obstructions or under the wheels. This system quickly retracts onto the train face when not needed, in order to free the coupling hitch for duty as required.
