Abstract: A multiple motion toy includes a stand and a body assembly overlying the stand. The body assembly includes a turning member connected to the stand. The turning member is rotatable relative to the stand about a substantially vertical rotation axis. A pivot member is connected to the turning member such that the pivot member is tiltable relative to the turning member about a pivot axis. The pivot axis extends transversely to the rotation axis. A neck member is connected to the pivot member such that the neck member is linearly reciprocable along a bobbing axis. The bobbing axis extends transversely to the pivot axis. A drive system is operative to rotate the turning member about the rotation axis, tilt the pivot member about the pivot axis, and reciprocate the neck member linearly along the bobbing axis. The pivot axis is reoriented as the turning member rotates whereby the pivot and bobbing axes are varied relative to the stand.

Abstract: A ballast for a gas discharge lamp includes a detection circuit which detects an operating state of the lamp in which the lamp current for the column discharge of one polarity is different from the lamp current for the column discharge of the other polarity by detecting the DC component of the voltage across the discharge lamp. The detection circuit includes (i) a device coupled such that a DC voltage is imposed there across when the lamp current is different for the column discharge according to one polarity verses the other polarity, and (ii) a sensing circuit for sensing the DC voltage across the device. The device may be a capacitive device, and in a particularly inexpensive implementation, is a DC blocking capacitor or a ballast capacitor. The sense circuit senses when the DC voltage across the device exceeds a threshold value, which may corresponds to fully-rectified state of the lamp or more favorably, to a lesser state of imbalance.

Abstract: A dimming ballast system wherein the light output of the lamp is controlled by a remote source. The ballast output voltage is regulated by a voltage control feedback loop, the dimming function being achieved by varying the set point of the control loop. The remote control signal, coded by interrupting the current flow to the ballast for a short period, is processed digitally by a microcomputer which generates information to vary the control set point. Circuit means are provided to control the filament voltage of the fluorescent lamps such that as the lamps are dimmed down, the filament voltage is maintained or slightly increased, thus prolonging lamp life and stabilizing the lamp light output.
