摘要： A downhole crystal-based clock that is substantially insensitive to the factors that cause frequency deviation. The clock may be maintained at a predetermined temperature using a temperature sensing device and a heating device, where the predetermined temperature corresponds to the temperature at which the crystal experiences only slight frequency deviation as a function of temperature. A microprocessor may monitor the clock and compensate for long-term aging effects of the crystal according to a predetermined algorithm. The predetermined algorithm may represent long-term aging effects of the crystal which were derived by comparing the crystal clock to a more accurate clock (e.g., an atomic clock) prior to placing the clock downhole. In this manner, the crystal-based clock may be substantially free from the factors that cause frequency, and therefore time variations.
摘要翻译：基于井下晶体的时钟，对引起频率偏差的因素基本不敏感。可以使用温度感测装置和加热装置将时钟保持在预定温度，其中预定温度对应于晶体仅作为温度的函数的轻微的频率偏差的温度。微处理器可以监视时钟并根据预定算法补偿晶体的长期老化效应。预定算法可以表示通过在将时钟放置在井下之前将晶体时钟与更准确的时钟（例如，原子钟）进行比较而导出的晶体的长期老化效应。以这种方式，基于晶体的时钟可以基本上没有引起频率的因素，并且因此也是时间变化的因素。

摘要： In some embodiments, an apparatus and a system, as well as a method and an article may operate to move fluid from at least one fluid container into a flow line so as to cause the fluid to contact at least one surface having a condition affecting sensor information provided by a sensor. Additional activities may include adjusting operation of a fluid transport mechanism based on the sensor information and baseline information, to continue moving the fluid and change the condition until the fluid is depleted from the at least one fluid container or the sensor information conforms to the baseline information to a selected degree. Additional apparatus, systems, and methods are disclosed.

摘要： In an acoustic logging system utilizing one or more acoustic sources, each with a specified radiation pattern around a source orientation, an acoustic signal is transmitted into a formation with a source oriented in a first source orientation. An acoustic waveform is received in response with a receiver oriented in a first direction. The slowness of the formation in the first direction is calculated using the received acoustic waveform.
