20110304482 | ABSOLUTE OPTICAL ENCODER WITH LONG RANGE INTENSITY MODULATION ON SCALE - An encoder configuration comprises a dual-modulation scale track pattern that provides a first intensity modulation component for producing periodic signals, and a second intensity modulation component for producing a long-range absolute signal. The dual-modulation scale track pattern increases the range-to-resolution ratio of the encoder without the use of additional scale tracks that would increase the width of the encoder components. The long-range signal may be encoded in the dual-modulation scale track pattern either by varying certain dimensions of pattern elements included in the scale track or by superimposing a layer including an optical density variation along on the track on pattern elements of similar areas. In either case, the net offset and/or amplitude levels of the associated signals are modified along the scale track. These modified offset and/or amplitude levels provide the basis for the long-range absolute signal. | 2011-12-15 |
20110304483 | Method and apparatus for text data input with an alphanumeric keypad for an electronic device - An alphanumeric keyboard is provided which includes a 3×4 key button configuration and five function keys. The 3×4, 12 key button and five function keys configuration provides optimal space for the user to conveniently press the desired keys for inputting text into a portable electronic device. The alphanumeric keypad minimizes the number of key presses to input a text message by organizing the alphabet in the order that the characters are most frequently used. To reduce the number of repeated key presses the keys designated by numerals 2-8 each display two alphabet characters, and keys 9, 0, *, and # each display three alphabet characters. The keypad offers two methods of text input via portable communication devices: 1) the conventional multi-tap method of text input; 2) the Alpha mode method. | 2011-12-15 |
20110304484 | LIGHT GUIDE HAVING A CAPACITIVE SENSING GRID AND RELATED METHODOLOGY - An electronic device may include a keypad having a plurality of predefined key areas and a light guide that may be used to illuminate the key areas. The light guide may include a capacitive sensing grid to sense user contact relative to the keypad. | 2011-12-15 |
20110304485 | Legend Highlighting - A method for manufacturing keycap includes applying a first coating layer on a surface of a keycap layer, applying a second coating layer on top of the first coating layer, etching at least a portion of the first coating layer to a first depth to form a first etched area, and etching at least a portion of the first etched area to a second depth to form a second etched area. | 2011-12-15 |
20110304486 | SOLAR KEYBOARD AND ELECTRONIC DEVICE USING THE SAME - A solar keyboard includes a base, a touch keyboard module and a solar cell. The touch keyboard module is disposed on the base and includes a transparent layer. The solar cell is selectively disposed over or below the transparent layer. An area of the solar cell is substantially equal to that of the touch keyboard module. Accordingly, the solar keyboard of the invention can absorb much more solar energy and then generate much more electric power. | 2011-12-15 |
