Abstract: A security network includes a distributed computing network that has redundant data paths. A plurality of addressable security feed transmitting devices each transmit a data feed over one or more of the redundant data paths. The data feed is representative of the area being monitored by the security feed transmitting device. One or more security feed receiving devices access the data feed from each addressable security feed transmitting device.

Abstract: In the secured pen holder of U.S. Pat. No. 6,167,596, a first resilient engagement between cover and base provides an indication of the replacement state in which the pen assembly can be replaced. A second resilient engagement between cover and base provides an indication of the use position in which the pen is held within the holder for use. A third resilient engagement between transport and base provides an indication that the transport is resiliently held in place at a position when the transport wall holds the pen tether and stop in place during the use state.

Abstract: An induction motor system, including a housing, a stator supported by the housing and having a plurality of stator winding conductors positioned about an axis of rotation, and a rotor mounted in the housing for rotation about the axis of rotation, is provided with an integral electronic controller for dynamically and programmably controlling the currents supplied to individual conductors of the stator winding. The stator winding conductors are connected in common at one end and are individually connected to a switching circuit at the other end. The switching circuit supplies positive or negative current pulses through selected conductors. Pulse width modulated signals generated by the controller simulate sine wave energizing signals to provide various operating configurations. By programmed variation of the fundamental frequency, pole configuration, phasing and power level, the rotating speed, starting, acceleration, torque, reversing, dynamic braking and efficiency are dynamically controlled.
