A method in a portable electronic device (100) including inputting a first word component, for example, a letter or stroke, displaying a first candidate list having at least a first completion candidate including the first word component, inputting a second word component, displaying a second candidate list having a second completion candidate, the second completion candidate including the first and second word components, and de-prioritizing the first completion candidate of the first candidate list relative to at least one other candidate of the second candidate list.
摘要:
A method and apparatus for entering text including tone marks and integral diacritics, such as Vietnamese, uses a compact keypad (110). The compact keypad has letters in alphabetical sequence, including letters with integral diacritics (142, 143, 146, 148) in the same order as they arrive in the Vietnamese alphabet series. The five tone marks (154,155,157,158,159) are positioned on five separate keys (124, 125, 127, 128, 129) of the compact keypad (110). The apparatus has an associated method (300) where a processor determines if a previous keypress represents a neutral vowel (350) and modifies the neutral vowel with a tone mark 360 if a current keypress has an associated tone mark.

A numeric keypad (100) for entering ideographic characters is provided. The numeric keypad (100) comprises a first set of input keys (102) corresponding to numerals 1, 2, 3, 4, and 5, and a second set of input keys (104) corresponding to numeral 6, 7, 8, 9, and 0. Each of the first set of input keys (102) has a predefined single character stroke, which complies with the GB18031 standard. The second set of input keys (104) is assigned a first particular sequence of the predefined single character strokes and a second particular sequence of the predefined single character strokes different from the first particular sequence of the predefined single character strokes.

Systems, program product, and methods for monitoring linearity of a down-hole pumping system assembly during deployment within a bore of a casing of a well positioned to extract hydrocarbons from a subterranean reservoir and selecting an optimal operational position for the down-hole pumping system assembly within the bore of the casing, are provided. Various embodiments of the systems allow an operator to ensure that a motor and pump of a down-hole pumping system assembly are installed in an optimal position in a well by ensuring alignment across the pump stages casing and motor casing. The alignment and linearity of the pump and motor can be crucial to run life of the pump and/or motor.
摘要:
An apparatus for estimating a property includes a hollow core tube and an input light guide disposed at least partially within hollow core tube. The apparatus also includes a second gap disposed within the hollow core tube and separated from the input light guide by an air gap width. The second gap is formed of a first solid material and has a second gap width. The apparatus also includes a third gap disposed at least partially within the hollow core tube and being further from the input light guide than the second gap. The third gap is formed of a second solid material and has a third gap width.
摘要:
A system for measuring downhole parameters is disclosed. The system includes: a carrier configured to be disposed in a borehole in an earth formation; at least one optical fiber sensor in operable communication with the carrier; a measurement assembly including an electromagnetic signal source configured to transmit a first interrogation signal into the optical fiber sensor and a detector configured to receive a reflected signal indicative of a downhole parameter in response to the interrogation signal; and a processor configured to automatically receive scattered signals from the optical fiber sensor, generate distributed scattering data indicative of a condition of the optical fiber sensor and analyze changes in the distributed scattering data to identify changes in the condition of the optical fiber sensor.
