Abstract: A remote controller for use with cable or satellite provided TV program signals in which an original “over the air” TV station's real channel assignment (such as channel 38) may be instead translated to a virtual channel (such as channel 14) by the cable or satellite service provider. The viewer may enter the TV station's real channel value and the remote controller automatically converts it to the virtual channel value prior to sending it as command to the controlled device, such as a TV-set, cable box or satellite receiver. Similarly, “over the air” TV station channel numbers which have not been intermediately translated (such as 4, 5, 12, etc.) may be entered by the viewer and directly sent to the controlled device. Additionally, single digit entries may be automatically prefixed with a leading ∅ to reduce likelihood for an entry error by the user.

Abstract: Portable remote controller for accessory television devices for program channel selection and other operating functions. A single uniquely identified keybutton enables the viewer to remotely reset a televisor's video input to an “unused” channel such as channel 3. After a reset, the remote controller's functions revert to whatever device was previously selected. A variation provides that intentional pressing of a a “device selection” button, such as a CBL “cable box select” button, for a few seconds implements the input reset mode to automatically urge a specific video input selection. Another variation senses an extent of a TV or other device's “select” keybutton action. A partial depression of the TV keybutton may merely initiate the usual device selection function. By further depressing the TV keybutton a preceptive wireless signal is automatically sent to remotely affirm the appropriate video input selection.

Abstract: An alternating current induction motor having a tapped RUN winding for developing different levels of stator field excitation which induces rotational torque into a rotor having an output member that drives various levels of mechanical load. Instant motor loading is sensed as a change in power factor or subsynchronous slip speed and the level of RUN winding excitation, together with the resulting magnetic field strength, is immediately changed to compensate for the sensed load changes. The change in RUN winding excitation is brought about by having a RUN winding the full extent of which may be coupled with a.c. power to produce magnetic field strength and resulting output member torque at least sufficient to operate the motor under minimum load conditions, and at least one tapped portion of the RUN winding which may be alternatively coupled with the a.c.

Abstract: An energy efficient electric motor is provided with a supplementary run winding arrangement which operates in conjunction with the motor's main run winding to produce a combined magnetic field with sufficient strength to operate the motor under full load. Less than full load operation obtains increased efficiency through a reduction of power flow to the supplementary run winding arrangement, which brings about a significant reduction in stator core structure (eddy current) losses and winding (resistance) losses. A controller may predetermine the normal amount of magnetic field strength necessary during each portion of the motor's usual operating cycle and variously modulate the instant level of power coupled with the supplementary run winding arrangment.
