摘要： A fiber optic cable for use in a downhole environment is disclosed. The fiber optic cable includes a tube having an interior region; an optical fiber disposed in the interior region of the tube; a gas in the interior region; and a gel in the interior region, wherein the gel is configured to reduce stress on the optical fiber in the presence of the gas at a temperature substantially near the flashpoint of the gel. One or more seals can be used to seal the gel and the inert gas in the interior region. In various aspects, the fiber optic cable can be used in a downhole environment.

摘要： An intermediate code and electronic device therefore uses a method for character entry that has the steps of entering a first character code into a memory buffer (320, 360, 390), entering an intermediate code into the memory buffer (310, 350, 380), entering a second character code into the memory buffer (332, 378), changing the intermediate code to one or more character codes (333, 336, 365, 375, 393, 396), and using a display engine to display one or more characters represented by the first character code, the one or more character codes, and the second character code. These intermediate codes are useful for reduced keypads where certain characters, such as ligatures, are difficult to access from the keypad.
