  • Patent number: 9363750
    Abstract: Access terminals are configured to decrease awake state durations (and conversely increase standby state durations) utilizing a preamble skip operation. According to one example, an access terminal may assign a finger of a receiver to receive a control channel transmission at a time after a beginning of a preamble of the control channel transmission, and before an initial boundary of a slot after a first slot of the control channel transmission, the preamble of the control channel transmission including information corresponding to a data rate of the control channel transmission. The access terminal may further be configured to decode the control channel transmission in accordance with a predicted data rate. Other aspects, embodiments, and features are also included.

  • Publication number: 20160096988
    Abstract: Pumpable process-fluid compositions comprise polyacrylamide, a non-metallic crosslinker and a pH-adjustment material. Such compositions have utility in the context of controlling lost circulation in subterranean wells. Upon entering at least one lost circulation zone, the compositions crosslink, thereby forming a barrier that minimizes or stops fluid flow from the wellbore into the lost circulation zone.

  • Patent number: 9284482
    Abstract: Compositions and methods are given for delayed breaking of viscoelastic surfactant gels inside formation pores, particularly for use in hydraulic fracturing. Breaking inside formation pores is accomplished without mechanical intervention or use of a second fluid. Acidic internal breakers such as sulfuric acid and nitric acid are used. The break may be accelerated, for example with a free radical propagating species, or retarded, for example with an oxygen scavenger.

  • Publication number: 20150234543
    Abstract: The present invention relates to communication technology and discloses an information processing method and an electronic device. The information processing method is applied in an electronic device. The touch display unit is capable of displaying at least one target object associated with the first application and displaying the first application in a small window or a full-screen window in response to the target object being touched. The full-screen window has a display area equal to an area where the touch display unit can accept a touch event and the small window has a display area smaller than the area where the touch display unit can accept a touch event. The small window is obtained by converting the full-screen window based on a first conversion parameter.

  • Publication number: 20150173093
    Abstract: Systems and methodologies are described that facilitate dynamically allocating demodulation resources of a wideband receiver to provide improved demodulation of simultaneously received signals. Signal-to-noise ratio (SNR) and/or packet error rate (PER) can be measured for the plurality of carriers to determine which demodulators related to the carriers require more resources than others to demodulate signals at a specified signal quality. Where the SNR of a related carrier is high and/or PER is low, the demodulator can require fewer resources than where the SNR of a related carrier is low and/or PER is high. In this regard, the resources are dynamically allocated among the demodulators and reallocated where SNR/PER changes and/or additional resources are made available.

  • Publication number: 20150071089
    Abstract: Access terminals are adapted to dynamically decrease awake state durations (and conversely increase sleep state durations) when operating in a slotted idle mode. According to one example, an access terminal can determine an offset corresponding to a time difference between the beginning of a preceding slot cycle and receipt of a first packet transmission. The access terminal can store information corresponding to the determined offset, and can employ the stored information to power on a receiver circuit after the beginning of a subsequent slot cycle by an amount of time corresponding to the determined offset. Other aspects, embodiments, and features are also included.

  • Patent number: 8916507
    Abstract: A wellbore treatment fluid is formed from an aqueous medium, a gas component, a viscosifying agent, and a surfactant. The surfactant is represented by the chemical formula: [R—(OCH2CH2)m—Oq—YOn]pX wherein R is a linear alkyl, branched alkyl, alkyl cycloaliphatic, or alkyl aryl group; O is an oxygen atom; Y is either a sulfur or phosphorus atom; m is 1 or more; n is a integer ranging from 1 to 3; p is a integer ranging from 1 to 4; q is a integer ranging from 0 to 1; and X is a cation. The fluid may be used in treating a subterranean formation penetrating by a wellbore by introducing the fluid into the wellbore. The fluid may be used in fracturing a subterranean formation penetrated by a wellbore by introducing the fluid into the formation at a pressure equal to or greater than the fracture initiation pressure.

  • Publication number: 20140076563
    Abstract: Compositions comprise polyacrylamide, a non-metallic crosslinker and a pH-adjustment material. Such compositions have utility in the context of remedial cementing, plug cementing in particular. The compositions may be pumped into a subterranean well, where they polymerize and form a support on which a cement plug may sit. The support may maintain the position of the cement plug in the wellbore and minimize cement-plug contamination.
