摘要: A downhole tool, such as a packer or liner hanger, has a mandrel on which slips are disposed for engaging a surrounding tubular downhole. When the tool is being run in or out of the hole, at least one magnetic component magnetically retains the slip adjacent the mandrel so the slip can be held away from the surrounding tubular. When the tool is set downhole, the initial magnetic retention can be broken, and the slips can be moved away from the mandrel to engage the surface of the surrounding tubular.

摘要: A method for enhancing the security of a quantum key distribution (QKD) system having QKD stations Alice and Bob. The method includes encrypting key bits generated by a true random number generator (TRNG) and sent to a polarization or phase modulator to encode weak optical pulses as qubits to be shared between Alice and Bob. Key bit encryption is achieved by using a shared password and a stream cipher. Bob obtains at least a subset of the original key bits used by Alice by utilizing the same stream cipher and the shared password.

摘要: A heater for a liquid has a combustion chamber, a jacket for the liquid extending about the combustion chamber and a burner head assembly connected to the combustion chamber. The burner head assembly includes a housing having a burner mounted thereon and a hollow interior. A control module and a fan are mounted in the hollow interior, the fan being connected to an electric motor. A compressor and a fuel pump are mounted on the housing and are operatively connected to the electric motor. The control module may include controls for exercising components of the heater prior to combustion, thereby verifying operation of these components. Preferably there is a speed control for the motor, such as a closed loop speed control which regulates motor speed and accordingly output of the heater. Preferably there is a backup system using a lookup table in the event that the closed loop speed control fails. Also preferably there is provision for monitoring flame sensor functionality by providing an indicator light which mirrors operation of the flame sensor. The heater may have a selective soft start for the coolant pump which operates only when required so as to reduce unnecessary chatter on the motor relay. A system is also provided for distinguishing true overcurrent faults from overcurrents arising from voltage changes during starting of the vehicle engine. Reignition algorithms are provided to restart the burner in the event of flame sputters caused, for example, by fuel bubbles, but shut off the heater in the event that the fuel is truly cut off.

摘要: A code library, or “language interface pack” library, is provided that can be integrated into a video game to detect new localizations of the video game dynamically, and to locate and load the most appropriate localized resources depending on user preferences and available localized game content. If no localized content is available in the preferred language, a fallback system ensures that the game always receives the location of existing game content in another language.

摘要: In a quantum key distribution (QKD) system, a method of autocalibrating the gating of a single-photon detector (SPD) unit is disclosed. The method includes exchanging photon signals (P1, P2) to establish a bit-error rate (BER). The method also includes performing a detector gate signal timing scan (314) that varies the signal arrival time (T) to establish an optimum arrival time (TMIN) corresponding to an optimum (e.g., minimum) BER. Detector gate signal timing dithering is then performed (318). This involves varying the detector gate signal arrival times about the optimum arrival time to ensure that the QKD system operates at or near an optimum BER.

摘要: A method of improving the security of a QKD system is disclosed. The QKD system exchanges qubits between QKD stations, wherein the brief period of time surrounding the expected arrival time of a qubit at a modulator in a QKD station defines a gating interval. The method includes randomly activating the modulator in a QKD station both within the gating interval and outside of the gating interval, while recording those modulations made during the gating interval. Such continuous or near-continuous modulation prevents an eavesdropper from assuming that the modulations correspond directly to the modulation of a qubit. Thus, an eavesdropper (Eve) has the additional and daunting task of determining which modulations correspond to actual qubit modulations before she can begin to extract any information from detected modulation states of the modulator.
