Abstract: An electromagnetic field signal communications system (100) is based on a specially configured sending transducer (30), having electrical conductors (32) wound onto a generally circular core (33) including an air gap (34) from which its electromagnetic fields (40) are generated when excited with input electrical audio or data (20) signals. The transducer (30) transmits by projecting these electromagnetic fields (40) onto adjacent signal receiving transducers (51/56) that transform the electromagnetic field (40) into proportional electrical signals. The electromagnetic fields (40) are transformed by a receiving transducer (51) located in an adjacent hearing aid device (50) such that input audio electrical input signals, which are processed by circuitry (53), bypass the hearing aid microphone (52) and are routed to the eardrum speaker (55).

Abstract: A multi-article storage carrier is based upon a sheet of flexible material comprising a plurality of compartments on one side for containing the articles, the sheet being folded at least once in each direction to form the carrier and enclose the articles securely. Securing and carrying means such as straps are provided on the surface of the sheet opposite the compartments so that they are exposed for use when the carrier is folded and/or rolled for carrying.

Abstract: An electromagnetic field signal communications system (200) is based on a pair of specially configured and positioned transducers (230a/230b), having electrical conductors (232) wound onto generally toroidal or C-shaped cores (233). The positioned cores include an air gap (234) from which its electromagnetic fields (40) are generated when excited with input electrical data (221a/221b) signals or sensed by induction via their corresponding electromagnetic flux fields. The pair of transducers (230a/230b) are ideally suited for unidirectional or bidirectional electromagnetic communications between electronic devices of distinct types. Data (221a/221b) transfer is facilitated via precisely positioning and aligning the transducer air gaps (235/235). Embodiments of systems teaching the use of portable hand held devices (210) in communications with a computer (260) and digital cameras or printers (265) are presented.
