Abstract: A device is disclosed including a security module to generate and update cryptographic keys to establish a secure relationship between the device and one or more station devices in a wireless video area network (WVAN) and a domain manager to maintain a list of the station devices that are authorized to operate in the WVAN.

Abstract: A radio frequency (RF) transmitter has a plurality of digitally controlled phased array antennas coupled to and controlled by the processor to transmit data. The processor is to enable one or more antennas to be turned off during a use of the apparatus to reduce a power consumption of the apparatus.

Abstract: A device is disclosed having a first radio component to enable the device to communicate with devices in a first wireless network via a first wireless communication protocol and a second radio component to enable the device to communicate with devices in a second wireless network via a second wireless communication protocol.

Abstract: A synthetic magnetodielectric composite material for absorbing electromagnetic radiation has a sheet of fabric having first and second surfaces. The fabric is formed of an insulating material. Magnetically permeable thread is disposed within the fabric. The magnetically permeable thread comprises a material having a permeability substantially greater than the permeability of free space. The fabric is impregnated with resin. The magnetically permeable thread is configured to provide predetermined permittivity and permeability within a selected frequency range, so as to provide desired absorption/transmission of electromagnetic radiation.

Abstract: A composite electromagnetic absorber provides increased EMR absorption while being thinner and/or lighter than prior art EMR absorbers. To accomplish this, synthetic dielectric materials are combined with either synthetic magnetic materials or magnetically lossy materials in such a way that the permittivity and permeability of the composite material are substantially matched over the desired range of frequency. The match in the permittivity and permeability allows the majority of the electromagnetic fields to enter the material where the electric and magnetic loss components absorb the electromagnetic energy.

Abstract: A multilayer-multiconductor microstrip circuit having reduced dimensions and minimal pulse distortion and crosstalk for high-speed, high-density digital application is created utilizing a microstrip having a plurality of substrates, each having a preselected dielectric constant of a magnitude which, combined with the height of each substrate, produces effective dielectric constants of the independent propagating nodes which are substantially equal.
