    • A communications device, such as a mobile telephone, fixed line telephone, computer with network access, or any other similar device which is equipped to communicate using network and/or telephony protocols, is provided, wherein before a call or other communications sessions is set up and made, a determination of the present time at the intended recipient of the call or session is made. In some embodiments, this determination of the time at the intended recipient's location is displayed to a user of the calling device to allow the user to decide whether to proceed with a call to the intended recipient. In other embodiments the determined time is compared with a set of one or more predetermined time bands during which calls to a recipient should not be made. Depending on the results of the comparison, the operation of the communications device is altered, for example, in one embodiment the call is not made, and the user preferably informed. In another embodiment, the user (caller) is advised that the call is being made at an inappropriate time for the intended recipient, and prompted to indicate whether the call should proceed. With such techniques, the problems noted above of unwanted calls being set up unnecessarily can be addressed.

    • 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.

    • A method of autocalibrating a quantum key distribution (QKD) system (200) is disclosed. The QKD system includes a laser ((202) that generates photon signals in response to a laser gating signal (S0) from a controller (248). The method includes first performing a laser gate scan (304) to establish the optimum arrival time (TMAX) of the laser gating signal corresponding to an optimum—e.g., a maximum number of photon counts (NMAX)—from a single-photon detector (SPD) unit (216) in the QKD system when exchanging photon signals between encoding stations (Alice and Bob) of the QKD system. Once the optimal laser gating signal arrival time (TMAX) is determined, the laser gate scan is terminated and a laser gate dither process (308) is initiated. The laser dither involves varying the arrival time (T) of the laser gating signal around the optimum value of the arrival time TMAX. The laser gate dither provides minor adjustments to the laser gating signal arrival time to ensure that the SPD unit produces an optimum (e.g., maximum) number of photon counts.

    • A method of autocalibrating the timing of the laser (202) in a quantum key distribution (QKD) system (200) is disclosed. Laser (202) generates photon signals (204) in response to a laser gating signal (S0) from a controller (248). The method includes first performing a laser gate scan (304) to establish the optimum arrival time (TMIN) of the laser gating signal corresponding to an optimum (e.g., minimum) bit-error rate BER (e.g., BERMIN) when exchanging photon signals between encoding stations (Alice and Bob) of the QKD system. Once the optimum laser gating signal arrival time (TMIN) is determined, the laser gate scan is terminated (306) and a laser gate dither process (308) is initiated. The laser gate dither involves varying the arrival time (T) of the laser gating signal around the optimum value of the arrival time TMIN. The laser gate dither provides minor adjustments to the laser gating signal arrival time to ensure that the system operates at or near the optimum BER.
    • 公开了一种在量子密钥分配(QKD)系统(200)中自动校准激光器(202)的定时的方法。 响应于来自控制器(248)的激光门控信号(S0),激光器(202)产生光子信号(204)。 该方法包括首先执行激光门扫描(304)以建立对应于最佳(例如最小)比特误码率BER的激光门控信号的最佳到达时间(T MIN)。 当在QKD系统的编码站(Alice和Bob)之间交换光子信号时,BER BER最小。 一旦确定了最佳的激光门控信号到达时间(T MIN),终止激光门扫描(306),并启动激光门抖动处理(308)。 激光门抖动涉及将激光门控信号的到达时间(T)变化到达到达时间T MIN MIN的最佳值。 激光门抖动对激光门控信号到达时间进行了微小调整,以确保系统在最佳BER或接近最佳BER时工作。

    • 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.
