Abstract: A readable and rewriteable card blank for use with a hand-held electronics device having a card reading and writing interface for aggregation of and management of personal electronic data sets is provided including a readable and rewriteable media disposed on a credit card form factor, a first touch enabled display, internal micro-circuitry such as an embedded smart chip, a proximity sensing capability characterized in that the personal electronic data sets are read into the card form factor selectively or collectively via a personal electronics device enabled as a smart phone for use in electronic transacting or fulfillment of electronic identification queries.

Abstract: An illuminated keyboard has at least one key carried by a support structure and operable to close an electrical contact on being depressed from above, the at least one key having a translucent top surface, a hollow space under the translucent top surface, and an opening into the hollow space other than through the top surface, and an electroluminescent illuminator comprising a region of electroluminescent material enabled to be inserted into the hollow space through the opening.

Abstract: A wireless headphone device has a first elongate portion having first and second opposite ends with an attachment interface at the first end, the first portion comprising an on-board power supply and a transceiver with functional circuitry, and a second elongate portion coupled pivotally to the first portion at the second end, and having an ear bud and a microphone at an end away from the pivotal coupling. The functional circuitry enables receiving and playing of audio from an MP3 player through the ear bud, and use as speaker and microphone for a wirelessly coupled telephone.
