Abstract: A display fixture that is enabled with location tracking systems to locate customers in a retail or trade environment and provide a more holistic experience for the customer that works through, rather than in competition, with the customer's mobile device. An App on a customer's mobile device enables location tracking systems on the mobile device such as GPS, WiFI tracking, Bluetooth Low Energy (BLE), in order to locate the customer within a retail or trade environment while the App is operational. Display fixtures are equipped with beacon devices to aid in the identification of the location of the customer mobile device relative to the display fixture. Proximity of the customer device may cause the App to deliver an experience to the customer via the mobile device and/or trigger a response in the display fixture itself.

Abstract: A coupling network for electromagnetic pulsed testing arrangements includes three stacks of toroidal ferrite cores. Two of the stacks are of identical diameter, the third stack has a diameter approximately equal to the combined diameters of the first two stacks. A copper tube looped through the central aperture of the first two stacks forms a primary winding. An insulated wire looped twice through the first two apertures forms a secondary winding of a 1:2 step-up transformer. The winding is extended through the aperture of the third stack. The third stack is operable to permit the laying in of a cable connected to a device under test. The cable forms the secondary of an isolation transformer.

Abstract: The disclosure relates to an assembly of stamped and formed parts for a coaxial connector with RF shielding ensured by a unitary ferrule intimately surrounding open seams in the stamped and formed parts. Also the disclosure relates to a blank which may be formed into a coaxial connector part having large diametrical transitions which ordinarily introduce RF attenuation but for the intimately surrounding unitary ferrule.
