    摘要： A system may generate from a first value, based on rounding information, a first security key that matches a second security key whenever the first value and a second value from which the second security key is generated differ by less than a non-zero predetermined amount. The second security key may be generated from the second value rounded to a multiple of a rounding interval that is nearest to the second value. The rounding information may include a rounding direction indication. The rounding direction indication may indicate the direction in which the second value is rounded to the multiple of the rounding interval nearest to the second value.

    摘要翻译： 无论何时产生第二安全密钥的第一值和第二值都相差小于非零预定量，系统可以基于舍入信息从第一值生成与第二安全密钥相匹配的第一安全密钥 。 第二安全密钥可以从舍入到最接近第二值的舍入间隔的倍数的第二值生成。 舍入信息可以包括舍入方向指示。 四舍五入方向指示可以指示第二值四舍五入到最接近第二值的舍入间隔的倍数的方向。

    摘要： In one embodiment, a clock on a network device is initialized, and then a first timing message is received at the network device from a reference device having a first timestamp indicating when the first timing message was transmitted from the reference device. The network device may then determine and store a one-way delay from the first timestamp to a first time at which the first timing message was received at the network device. In response to restarting the clock, the network device may receive a second timing message from the reference device having a second timestamp indicating when the second timing message was transmitted from the reference device. The network device may then calibrate the clock such that a second time at which the network device received the second timing message is the second timestamp plus the stored one-way delay.

    摘要： Disclosed is a radiation detector which includes at least one photoconductive detector and a modulator, which modulates in an on-off manner radiation passing to the photoconductive detector from a radiation source. A bias source is connected to one terminal of the photoconductive detector. A first amplifier is connected to the other terminal of the photoconductive detector, and a second amplifier receives an output of the first amplifier. A first phase detector detects the phase of modulation of the radiation source by the modulator and generates a reference signal relating thereto. A switch in the second amplifier changes, in response to the reference signal generated by the first phase detector, the second amplifier between an inverting state and a non-inverting state as the modulator changes the phase of modulation of the radiation.
