There is described a keyboard including user-operable alpha-numeric keys. One or more identification devices associated with the user-operable keys are included in the keyboard. When placed in proximity to the keyboard, the one or more identification devices selectively communicate with a digital apparatus in response to user-actuation of the user-operable keys. The keyboard comprises a flexible substrate for enabling the keyboard to be folded into a non-deployed inactive state, and unfolded into a deployed active state for communicating with the digital apparatus. When in proximity thereto, the keyboard communicates with the apparatus by way of near-field magnetic and/or electrostatic coupling. The keyboard includes an intermediate resonant circuit for interfacing between the one or more identification devices and the digital apparatus; the resonant circuit includes a component spatially disposed to overlay a first region onto the digital apparatus in use, and to overlay a second region coupled to the one or more identification devices in use for coupling signals therebetween. The keyboard is especially useful for mobile telephones and personal digital assistants (PDAs) for rendering data entry easier.
A keyboard (100) including a plurality of user-operable alpha-numeric keys (240), said keyboard (100) including one or more identification devices (220) associated with said user-operable keys (240), and wherein said one or more identification devices (220) are operable to selectively communicate with a digital apparatus (10) placed in proximity of the keyboard (100) in response to user-actuation (250) of one or more of said user-operable keys (240),
A keyboard (10) as claimed in any one of the preceding claims, wherein said first region (130) is disposed substantially centrally in said keyboard (100) when deployed in its active unfolded state.
A keyboard (10) as claimed in any one of the preceding claims, said keyboard (100) having its keys (240) selectively spatially disposed to assist with one or more of:
A keyboard (10) as claimed in any one of the preceding claims, said keyboard (100) including a source of power (300) therein, said source of power (300) being coupled in operation to energize said one or more identification devices (220) in an event that insufficient power is couplable from said digital apparatus (10) via said intermediate resonant circuit (140, 150;
A keyboard (100) including a plurality of user-operable alpha-numeric keys (240), said keyboard (100) including one or more identification devices (220) associated with said user-operable keys (240), and wherein said one or more identification devices (220) are operable to selectively communicate with a digital apparatus (10) placed in proximity of the keyboard (100) in response to user-actuation (250) of one or more of said user operable keys (240),
A method of coupling a keyboard (100) including a plurality of user-operable alpha-numeric keys (240) in communication with a digital apparatus (10) placed in proximity of said the keyboard (100), said keyboard (100) including one or more identification devices (220) associated with said user-operable keys (240), said one or more identification devices (220) being operable to selectively communicate with said digital apparatus (10) in response to user-actuation (250) of one or more of said user operable keys (240),
