摘要： Methods of using water-soluble hydrophobically modified polymers to treat intervals of a subterranean formation having variable permeabilities. An exemplary embodiment provides a method of treating an interval of a subterranean formation having a permeability that varies. The method comprises contacting the interval with a water-soluble hydrophobically modified polymer capable of selectively reducing the effective permeability of the interval to water without a comparable reduction of the effective permeability of the interval to hydrocarbons. The hydrophobically modified polymer modifies the interval to have a more uniform permeability without substantially preventing the flow of fluids through the interval. The method further comprises introducing a treatment fluid into the interval. The more uniform permeability of the interval allows for a more uniform treatment of the interval by the treatment fluid than would be allowed without treatment of the interval with the hydrophobically modified polymer.

摘要： A system and method for simultaneously receiving first and second ensembles. The first ensemble includes a first signal from a first satellite, a first signal from a second satellite and a first signal from a terrestrial repeater. Likewise, the second ensemble includes a second signal from the first satellite, a second signal from the second satellite and a second signal from the terrestrial repeater. The inventive receiver further includes a mechanism for selectively outputting signals transmitted within the first and second ensembles. In the illustrative embodiment, the first signal from the second satellite is identical to the first signal from the first satellite. Similarly, the first signal from the terrestrial repeater is identical to the first signal from the first satellite.

摘要： Two playing pieces each include a body portion, a shield having at least two hinged segments attached to the body portion, a first control mechanism operable to select one of the hinged segments as a blocked segment, a projecting element attached to the body portion and having a raised position and at least two lowered positions, and a second control mechanism operable to select one of the lowered positions as an active position. The two playing pieces can be placed on a track structure at opposite respective ends for movement towards each other along respective paths of movement. In one possible outcome, the projecting element of one of the playing pieces strikes the blocked segment of the shield of the other playing piece and in another outcome the projecting element strikes an unblocked segment of the shield of the other playing piece.

摘要： In a time division, multiple access system, a base station (102) transmits an isochronous beacon (404, 422) at the start of each frame (400), conveying control and timing information. Following the isochronous beacon (404), isochronous time slots (414, 416, 418, 420) are dynamically allocated for communication of isochronous data. After communication of the isochronous data, the remainder of the frame (400) before the next isochronous beacon (422) is used for transmission of packets of asynchronous data. This technique gives priority to the isochronous data, which is real time, while also maximizing the bandwidth allocated for asynchronous data. A single transmitter circuit (124, 158) and receiver circuit (122, 156) at each station are used for communication of both isochronous data and asynchronous data.

摘要： A data processor (20) which flexibly encrypts data within different address ranges includes an encryption determination circuit (50) to monitor an address conducted on an internal address bus (22) and when the address is within certain predefined ranges, perform encryption or decryption of address and/or data. For example the encryption determination circuit (50) may be used to selectively enable a data encryption-decryption circuit (60). When the data encryption-decryption circuit (60) is disabled, data conducted on an internal data bus (23) becomes "cleartext", i.e., non-encrypted. In one embodiment, the data encryption-decryption is performed in partial dependence on the address itself, and the address conducted to the external address bus is itself selectively encrypted as well.

摘要： A surgical suture retainer retains the suture in an epitrochoidal, or hourglass configuration. One embodiment includes an insert member mounted to one of several foldable connected panels of the suture retainer. The insert member preferably has first and second wings which fold over to form a suture retaining pocket. The suture is held in a looped configuration having an hourglass shape. Another embodiment employs tabs cut from one of the panels to retain the suture in the hourglass shape. Yet another embodiment employs a cover sheet bonded to a base panel, wherein bonding areas are located to maintain the suture loop in an hourglass shape.
