Abstract

A keypad has a substrate carrying an array of sense elements arranged to change state in response to keypad operation, a flexible cover disposed above the substrate and having an exposed surface defining an array of independent key regions, with combination key regions defined in interstices between adjacent independent key regions, and an array of discrete snap elements extending between the cover and the substrate and spacing the cover from the substrate.

Claims

42 AMENDED CLAIMS
[received by the International Bureau on 13 August 2002 (13.08.02); original claims 45 and 58 amended; remaining claims unchanged (4 pages)] 37. The telephone of claim 36 wherein the electronic circuit is further adapted to, in response to said additional input, initiate a telephone call using the telephone number.
38. The telephone of any of claims 34 through 37 wherein the electronic circuit is adapted to register numerical output according to the numerals associated with the numerical key regions.
39. A method of dialing a telephone, the method comprising entering a desired sequence of alphanumeric characters including at least one alpha character, the telephone generating a corresponding sequence of numerals by transposing the alpha character into one of the numerals 2 through 9 according to standard telephone keypad letter-number correspondence,
40. The method of claim 39 further including instructing the telephone to generate the corresponding sequence of numerals after the alphanumeric sequence has been entered.
41 , The method of claim 39 or claim 40 wherein the desired sequence of alphanumeric characters is entered on a keypad including at least 24 individual key regions, each key region corresponding to a different alphabet letter.
42. The method of any of claims 39 through 41 wherein the desired sequence of alphanumeric characters is in the form of a pronounceable utterance and entered by pronouncing the utterance.
43. The method of any of claims 39 through 42 wherein the sequence of alphanumeric characters includes a series of alpha characters.
44. The method of claim 43 wherein the series of alpha characters spells a pronounceable text.
