摘要:
The invention is a system for selecting and previewing a configuration for a wall module before a download of the configuration to the wall module. The configuration may be selected from a set of standard applications or it may be a customized standard application. The configuration may instead be a new application. The configuration may be changed, such as screen segment selection, during a preview of it. A memory usage meter may indicate how much memory is used relative to the amount available in the wall module for the configuration. Also the system may have an autobind to a controller feature for time parameters. New application or customized standard application configurations may be saved to a library for future use.

A post phase-inverter master volume regulator for use in combination with a tube-type musical amplifier having a phase-inverter tube. The signals at both sides of the phase-inverter tube's DC voltage plate are extracted from the amplifier for processing by the master volume regulator. In one embodiment, such signals are extracted by inserting a male/female tube base between the amplifier's phase-inverter tube and its socket. The two voltage plate signals are then transmitted through a multiconductor umbilical to an exterior enclosure. Each signal is connected to ground through its respective user adjustable rheostat, permitting the user to simultaneously change the inverter-tube's two voltage signals (and vary the amplifier's volume). The regulator may also include circuitry adapted to provide a bass-boost, and/or a high frequency cutoff. Sometimes, first and second volume controls may be provided to permit a user to quickly change between two volume settings. In another embodiment, a dual-ganged pot, for controlling the volume, would be mounted directly in the tube base, thereby eliminating the need for an umbilical and an exterior enclosure.

The stator yoke comprises a magnetic material. The machine further includes a shaft rotatably mounted in the stator yoke, the shaft comprising a non-magnetic material. The machine further includes a rotor assembly rotationally engaged with the shaft. The rotor assembly includes a rotor disk extending between the armature coils, the rotor disk having an inner portion and an outer portion. The outer portion of the rotor disk includes a number of circumferentially-spaced, magnetic poles. The rotor disk is coupled to the shaft for rotation about the shaft and generation of a rotating permeance wave. The stationary superconducting field coil is disposed between the stator yoke and the rotor disk, and the stationary superconducting field coil is configured as a stationary magneto-motive force (MMF) source for the rotating permeance wave produced by the rotor assembly to produce a rotating magnetic field.

A machine includes a rotatable rotor assembly having a number of salient poles. The machine further includes a stationary stator assembly having concentric inner and outer stators, at least one stationary superconducting field coil and at least one stator coil. The stationary superconducting field coil is disposed between the inner and outer stators and is mounted on at least one of the inner and outer stators. The stationary superconducting field coil and the salient poles are configured relative to each other, such that when the rotor assembly is rotated relative to the stator assembly around a predetermined axis, a rotating magnetic field is produced with an airgap flux direction substantially along the predetermined axis. The interaction between the stationary superconducting field coil and the rotating poles provides the only source of a time varying magnetic flux supplied to the stator coil.
