Abstract: The present invention relates to character input methods for miniaturized electronic devices having a reduced user input interface, wherein the methods use the unequally distributed frequencies of words and numbers in a dictionary or a file to predict the most likely user input. The invention pertains to a method for entering a word into a user interface of an electronic device, wherein the characters of the word can be selected from a character set stored in the electronic device. The method comprises generating and displaying a character subset, the generating of a character subset for browsing of a character set which includes at least one character, wherein the character subset includes characters from among which, according to an inference logic, the next character for the word is most probably selected, and displaying the character subset on a display of the electronic device for browsing and selecting the next character.

Abstract: A charging circuit for charging accumulators, in the case of which current measurement is carried out in the line to the accumulator in order to monitor the charging process. In order that it unnecessary to carry out any internal voltage doubling to produce a reference voltage, a small constant current is taken from the output current in order to produce the reference voltage. At the start of the charging process or in order to reproduce a normal, controlled charging after a short-circuit, a circuit element is present which ensures that a small constant current always flows to produce the reference voltage.
