Abstract: A staggered keyboard for use with a portable device is provided. The staggered keyboard includes a plurality of keys arranged into a plurality of rows of keys. For each row of keys, the labeling of the keys is arranged in either a linear or an arced relationship depending upon the key layout, but the key centers are staggered from key to key along at least two distinct reference lines or arcs so that adjacent keys can be placed in overlapping and/or contiguous configurations thereby minimizing the size of the keyboard layout. By staggering the key centers while maintaining a familiar layout of the key labels, typing efficiency can be maintained while the overall size of the keyboard is reduced.

Abstract: A mobile electronic device having a keyboard has a cover plate acting as a dial keypad. The keypad has a push-through, hinge-spring design that activates only one of two keyboard keys underlying a dial key and allows backlighting transmissivity. A translucent material can be used to allow the keyboard key backlighting to be coupled through to a top dial key. The keypad creates an aesthetically balanced dial keypad arrangement over a QWERTY keyboard. A preferable mechanical implementation allows backlighting and has an offset contact and spring design to activate one of the two underlying keys. This activation simplifies the software implementation for executing the dial number since the signal is coming from one address rather than having to make a determination of whether it is coming from one or two addresses. Moreover, the resulting dial key press has a standard single click feel.

Abstract: The invention provides a device and method for providing backlight to a display in an electronic communication device. The device comprises: a lens to collecting ambient light from outside the device; a body to transmit the ambient light from the lens to a backlight system for the display for dispersion within the backlight system. The backlight system then provides the light as a backlight to the display. A reflector may be provided for the device. An internal shutter may also be provided to block light from escaping out of the lens.

Abstract: System and method for informing a user of functions or characters associated with keys on a mobile communications device includes a keyboard operable to input DTMF codes and a display screen operable to display information. The display screen is also operable to display a virtual representation of at least a portion of the keyboard. The virtual representation includes help information on one or more virtually represented keys of the keyboard. This help information informs a user of an associated telephone function or character of one or more keys that are virtually represented on the display.

Abstract: A wireless handheld communication device having a housing containing a display screen located above a physical keyboard. The keyboard includes a plurality of physical keys and corresponding indicia. Some of the keys are associated with alphabetic characters corresponding to a QWERTY array of letters A-Z and some are associated with numeric characters 0-9 corresponding to a telephone keypad arrangement. At least some of the keys associated with numeric characters are overlaid on the physical keys associated with alphabetic characters. A microprocessor is included that runs the device in at least a telephony mode, an email mode and at least one additional mode. The microprocessor displays a key-function map on the display screen indicative of enabled functions associated with particular physical keys of the keyboard which are different from any function signified by the indicia associated with the respective particular physical key.

Abstract: In a portable electronic device having a battery compartment and a removeable cover therefor, the battery compartment and cover are configured to accommodate batteries of at least two different sizes.

Abstract: A hand-held electronic device with a keyboard, thumbwheel, display and associated software is optimized for use of the device with the thumbs. The associated software has a plurality of features to optimize efficient use of the limited keyboard space and encourage the use of the device by thumb-based data entry through the thumbwheel and/or through a combination of minimal number of keystrokes. Software features include international character scrolling, and auto-capitalization. The keys on the device keyboard are optimally shaped and configured for thumb-based input.

Abstract: An improved handheld electronic device having a reduced keyboard provides facilitated language entry by making available to a user certain words that a user may reasonably be expected to enter. In some situations, certain words can be stored, for example, in a temporary dictionary for use in particular situations. For instance, the names of the recipients of an electronic message might be stored in a temporary dictionary for rapid retrieval when entering a salutation in the message. As another example, a number of the words in an existing electronic message may be stored in a temporary dictionary and made available to a user when replying to or forwarding the message since the existing message might include words that the user might reasonably be expected to type in the reply message or the forwarded message.
