Abstract: A video switching and control system is described that provides compatibility with conventional analog cameras while also accepting network IP type cameras. The system offers reduced control latency, improved recording efficiency, and more flexible display features with greatly improved performance and update rates.The system offers greatly reduced wiring and installation complexity thus improving reliability. The architecture is scalable and expandable in either the analog camera count or the IP camera count. The system integrates these two camera technologies so that the camera source or recorder is transparent to the user. Each user can control all video sources, analog, IP, or recorded, from one keyboard and one or more monitors at each work station.The unique all digital solution provides digital reliability and broadcast quality performance. The solution is significantly smaller and substantially lower cost the previous solutions, and offers higher monitor output capacity without the need for expensive down framing approaches currently used in the industry.

Abstract: A multi-channel filtering system for use with a transceiver includes a front-end multi-pole, multi-throw switch, a back-end multi-pole, multi-throw switch, and a plurality of filters. The front-end switch includes a receive pole, a transmit pole, and a plurality of switch throws. The back-end switch also includes a receive pole, a transmit pole, and a plurality of switch throws. Each of the plurality of filters has first and second ports, each first port coupled to one of the switch throws of the front-end switch, and each second port coupled to one of the switch throws of the back-end switch. Using this configuration, filters of differing bandwidths can be switched in during signal reception and/or transmission, thereby tailoring the communication rate to the particular conditions.

Abstract: Coaxial cables each having a cylindrical electrically conductive outer shield and a central conductive wire insulated from the shield are conductively coupled through a connector to coplanar conductors on a dielectric substrate. The conductors converge toward an opening in the substrate. The coplanar conductors alternately are ground and signal conductors. Each coaxial cable shield is conductively coupled to two ground conductors and the cable wire is conductively coupled to the signal conductor between the two ground conductors. At the substrate opening the ground and signal conductors are conductively coupled to planar stripline waveguide ground and signal blades, respectively. Ground blades between the signal blades are a factor in controlling the signal blade impedance and provide isolation between the signal blades. Each blade is perpendicular to the substrate and has a pitch angle such that the blade extends through the opening below the substrate. A wire or needle probe is conductively coupled to the blade distal end. The needle end is adapted to contact a conductive pad on an IC (integrated circuit) chip. The coplanar conductors and stripline blades are configured to maintain substantially constant characteristic impedance in the signal conductors and their respective blades and to isolate signals in the signal conductors and blades from one another.

Abstract: A quadrature ring oscillator for high clock-rate applications is disclosed. A quadrature LC ring oscillator may use two stages of LC oscillators and variable mixers to provide consistent oscillation even at high clock rates. One stage of the quadrature ring oscillator comprises a first resonating element having an input and an output, and a first variable summer having L and P inputs and an output, with its L input being connected to the output of the first resonating element. The output of the first variable summer is connected to the input of the first resonating element The first variable summer may generate its output at a first phase by combining the L and P inputs. A second stage of the LC ring oscillator comprises a second resonating element, which has an input and an output, with its output being connected to the P input of the first variable summer. An inverter is used to produce an inverted signal of the output of the first resonating element. This stage also comprises a second variable summer having L and P inputs and an output, with its output connected to the input of the second resonating element. The P input of this second variable summer is connected to the inverted signal from the inverter and the L input is connected to the output of the second resonating element. The second variable summer may generate its output at a second phase by combining its L and P inputs.
