2. Magic tee - Wikipedia

   en.wikipedia.org/wiki/Magic_Tee

   A magic tee (or magic T or hybrid tee) is a hybrid or 3 dB coupler used in microwave systems. [1] It is an alternative to the rat-race coupler . In contrast to the rat-race, the three-dimensional structure of the magic tee makes it less readily constructed in planar technologies such as microstrip or stripline .

3. HAWK beacon - Wikipedia

   en.wikipedia.org/wiki/HAWK_beacon

   Emergency-vehicle hybrid beacons, for emergency vehicle facilities (i.e. fire stations), use the same signal head design, and uses an alternating flashing red aspect to protect departing emergency vehicles. The only distinguishing part of the design is a different sign, R10-14, which is used with the signal. Unlike at a HAWK beacon, drivers are ...

4. Stingray phone tracker - Wikipedia

   en.wikipedia.org/wiki/Stingray_phone_tracker

   The Stingray acts as a cellular tower to send out signals to get the specific device to connect to it. Cell phones are programmed to connect with the cellular tower offering the best signal. When the phone and Stingray connect, the computer system determines the strength of the signal and thus the distance to the device.

5. Cross-device tracking - Wikipedia

   en.wikipedia.org/wiki/Cross-device_tracking

   Now, cross-device tracking has evolved into a new, radical form of surveillance technology which enables users to be tracked across multiple devices, including smartphones, TVs, and personal computers through the use of audio beacons, or inaudible sound, emitted by one device and recognized through the microphone of the other device, usually a ...

6. Power dividers and directional couplers - Wikipedia

   en.wikipedia.org/wiki/Power_dividers_and...

   Now any matched 4-port with isolated arms and equal power division is called a hybrid or hybrid coupler. Other types can have different phase relationships. If 90°, it is a 90° hybrid, if 180°, a 180° hybrid and so on. In this article hybrid coupler without qualification means a coupled-line hybrid. [26]

   HIDRA being assembled as of December 2014 (photo: Daniel Andruczyk) The Hybrid Illinois Device for Research and Applications (HIDRA) is a medium-sized toroidal magnetic fusion device housed in the Nuclear Radiation Laboratory and operated by the Center for Plasma-Material Interactions (CPMI) within the Department of Nuclear, Plasma and Radiological Engineering at the University of Illinois at ...

8. Hybrid integrated circuit - Wikipedia

   en.wikipedia.org/wiki/Hybrid_integrated_circuit

   An (orange-epoxy) encapsulated hybrid circuit on a printed circuit board (PCB).. A hybrid integrated circuit (HIC), hybrid microcircuit, hybrid circuit or simply hybrid is a miniaturized electronic circuit constructed of individual devices, such as semiconductor devices (e.g. transistors, diodes or monolithic ICs) and passive components (e.g. resistors, inductors, transformers, and capacitors ...

9. Hybrid Access Networks - Wikipedia

   en.wikipedia.org/wiki/Hybrid_Access_Networks

   The second deployment scenario is where the network operator provides a hybrid CPE router to each subscriber and installs a Hybrid Aggregation Gateway (HAG) inside its access networks. The Hybrid Aggregation Gateway plays an important role in balancing the packets sent by and destined to the hybrid CPE router over the two access networks.
