Patent number: 7254366Abstract: A system and method communicate signals between a portable unit and a communications system. The portable device communicates with a base unit using inductive coupling. The base unit is further connected to a wider communication system such as a telephone network. Multiple, orthogonally arranged transducers are used in the base unit to provide a more complete magnetic field and to prevent mutual inductance nulls which are otherwise present in a magnetic field. The use of short-range inductive coupling minimizes the power requirements and limits interference with other sources. The inductive coupling may also be used to recharge a battery in the portable device.Type: GrantFiled: March 18, 2005Date of Patent: August 7, 2007Assignee: Aura Communications, Inc.Inventors: Vincent Palermo, Patrick J. Cobler, Neal R. Butler

Patent number: 6819762Abstract: An ear mounted speaker assembly provides improved internal and external stability of a “in-the-ear” headset. A housing containing a speaker further contains an extender, audio portion and electrical compartment. The extender is adapted to rest in the intertragic notch of the ear. The audio portion is mounted to the extender and is of greater width than the extender. The audio portion is adapted to be positioned within the lower concha behind the tragus and antitragus of the ear. The compressible retainer extends from the surface of the housing and presses against the upper concha of the ear. The strut extends from the lower surface of the housing below the extender and extends downward outside the intertragic notch and presses against skin to stabilize the speaker assembly within the ear. Compressible retainers may be interchangeable and may come in a kit containing a plurality of interchangeable compressible retainers of a variety of shapes.Type: GrantFiled: September 10, 2001Date of Patent: November 16, 2004Assignee: Aura Communications, Inc.Inventors: Andrew R. Jones, Andrew G. Ziegler, Charles M. Marshall, Timothy E. White

Publication number: 20020160722Abstract: One aspect of the present invention is generally directed towards a system and method of tuning a transducer for transmitting and receiving a wireless signal. In an illustrative embodiment, a single transducer is coupled to a first or second circuit for either transmitting or receiving, respectively. Generally, electrical characteristics of the first circuit are adjusted to increase a magnetic field generated by the transducer. Conversely, electrical characteristics of the second circuit are adjusted to increase a signal generated by the transducer for receiving a magnetic field. Accordingly, a single transducer device can be tuned for either transmitting or receiving a corresponding wireless signal.Type: ApplicationFiled: December 3, 2001Publication date: October 31, 2002Applicant: Aura Communications, Inc.Inventors: Domenic F. Terranova, Vincent Palermo

Publication number: 20020132585Abstract: Contents of one or more received messages can be analyzed to determine whether a transceiver device generating the inductive field has already been programmed with a unique communication code. If not, bidirectional communications can be established to program the transceiver device with a unique communication code over an inductive link. Orientation or position of a transceiver device can be used to initiate a process for programming a communication code. Generally, the communication code can define a unique relationship between two or more transceiver devices.Type: ApplicationFiled: March 15, 2002Publication date: September 19, 2002Applicant: Aura Communications, Inc.Inventors: Vincent Palermo, Charles M.

Patent number: 5982764Abstract: A magnetic induction time-multiplexed two-way short-range wireless communications system, and related method, includes a first portable unit and a second portable unit. The first portable unit receives first unit input signals and provides first unit output signals. Also, the first portable unit includes a first unit transducer system for generating a first inductive field based upon the first unit input signals during a first time slot and for converting a second inductive field into the first unit output signals during a second time slot. The second portable unit receives second unit input signals and provides second unit output signals. Also, the second portable unit includes a second unit transducer system for generating the second inductive field based upon the second unit input signals during the second time slot and for converting the first inductive field into the second unit output signals during the first time slot.Type: GrantFiled: April 23, 1997Date of Patent: November 9, 1999Assignee: Aura Communications, Inc.Inventors: Vincent Palermo, Patrick J.

Patent number: 5912925Abstract: A magnetic communication system includes a transmitter have a single coil transducer, and a receiver having a three orthogonally oriented coil transducers. The signal processing circuitry in the receiver adjusts the phases of the signals received by the three transducers to produce signals which are in-phase. The signals are then summed to provide an output signal from the receiver. The processing circuitry adjusts the phases of the incoming signals either serially or in parallel. Transmissions from the receiver to the transmitter are also phase adjusted in accordance with the same adjustments used in reception.Type: GrantFiled: August 13, 1996Date of Patent: June 15, 1999Assignee: Aura Communications, Inc.Inventors: Vincent Palermo, Patrick J.
