US Classification:

607 32, 607 60

Abstract:

An implantable medical device (“IMD”) as described herein is configured to support concurrent multichannel data communication with one or more other devices within a body area network corresponding to a patient. The IMD, and possibly other devices within the body area network, can support the multichannel communication with any number of additional IMDs implanted within the body of the same patient.

US Classification:

252582, 342175, 343904, 333219

Abstract:

Composite material, devices incorporating the composite material and methods of forming the composite material are provided. The composite material includes interstitial material that has at least one of a select relative permittivity property value and a select relative permeability property value. The composite material further includes inclusion material within the interstitial material. The inclusion material has at least one of a select relative permeability property value and a select relative permittivity property value. The select relative permeability and permittivity property values of the interstitial and the inclusion materials are selected so that the effective intrinsic impedance of the interstitial and the inclusion material match the intrinsic impedance of air. Devices made from the composite include metamaterial and/or metamaterial-inspired (e.g. near-field LC-type parasitic) substrates and/or lenses, front-end protection, stealth absorbers, filters and mixers. Beyond the intrinsic, applications include miniature antenna and antenna arrays, directed energy weapons, EMI filters, RF and optical circuit components, among others.

International Classification:

H01F 38/14

US Classification:

307104

Abstract:

Techniques are described for wireless energy transmission and projecting magnetic fields over relatively long near-fields. In one example, a device for transmitting near-field energy comprises at least one source that generates a radiofrequency (RF) signal, an antenna that generates near-field signals from the RF signal, and a plurality of sub-wavelength sized elements that form a lens in communication with the antenna that captures the near-field signals, generates near-field energy, and re-directs the near-field energy toward an object in the near-field of the lens, where the sub-wavelength sized elements are disposed about the antenna.

International Classification:

H01Q 19/15
H01Q 1/24
H01Q 25/02

Abstract:

A radar system is used to implement a method. The method includes transmitting radar signals from a radar system located in an environment having reflective surfaces, receiving reflected signals via an antenna, deriving angular information as a function of the antenna configuration, and providing an output as a function of the received reflected signals and the derived angular information, wherein the output is representative of a characteristic of the environment. The antenna may be a patch antenna with patches having overlapping gain patterns or patches arranged as a leaky wave antenna to provide information in received signals from which angular information is derivable.

Abstract:

A resonant antenna for long-range wireless power transfer and communications. The antenna may be powered by a source at a frequency that is resonant for the antenna or harmonic(s) of the resonant frequency. The loop or antenna may be a wire laid out in a physically large network or constitute wiring of a building or other place. The antenna may be placed in a high index material, which results in the antenna to be a physically smaller size for the same electrical size. The antenna may be driven with an electrical power signal. Power may be picked up by another or secondary antenna from the source antenna at the resonant frequency or harmonic(s). Communications may also occur between the antennas. Because of a near-field effect, emanation of electromagnetic fields is primarily limited extensively to just between the antennas. A little stray electromagnetic field exists that others cannot easily intercept.
