Title: Method and apparatus for controlling the output voltage of an ac electrical system
Inventor: KONISHI HIROO
IPC: G05F1/70
Filed: 1992-06-11
Granted: 1996-07-30
Abstract: The present invention relates to an AC system having, for example, a voltage source, an inductance and a load has connected thereto an apparatus for controlling the phase and amplitude of the voltage of the system.  The instantaneous current and voltage in the AC electrical system are measured and power measurements derived therefrom.  The power measurements may be instantaneous real and imaginary power, instantaneous active and reactive power, or active and reactive power averaged over less than one cycle.  The power measurements are then used to derive phase related control values, on the basis of which control signals are generated to a converter.  The action of the converter in accordance with the control signals thus controls the amplitude and phase of the voltage.  By use of power measurements, it is not necessary to measure the phase of the voltage of the AC system.

Title: Constant gap document feeder and method of operation thereof
Inventor: GUTHMUELLER RODNEY
IPC: B65H43/00
Filed: 1991-03-21
Granted: 1999-06-15
Abstract: A controller (25) ensures a desired constant gap between a trailing edge of a first document and a leading edge of a subsequent document. The controller (25) decreases the speed of a feeder transport (22) upon the detection of a leading edge of a first document at an entrance to a take-away transport (24). The controller (25) then linearly increases the speed of the feed transport (22) along a speed ramp (R) until a trailing edge of the first document is detected. Upon the detection of the trailing edge of the first document, the controller (25) sets the speed of the feeder transport (22) to a constant value (S4). Thereafter the controller (25) detects a leading edge of the subsequent document.  The controller (25) determines the magnitude of an initial gap (I) between the trailing edge of the first document and the leading edge of the subsequent document.

Title: Apparatus and method using compressed codes for scheduling broadcast information recording
Inventor: YUEN HENRY C
IPC: G11B31/00
Filed: 1992-12-11
Granted: 2007-07-31
Abstract: Digital compressed codes, asso-ciated with advertisements enable a user to selectively record additional informa-tion, which would be broadcast on a television channel at a later time. The advertisement could be print advertise-ment or broadcast advertisement on tele-vision or radio. The user enters the digi-tal code (I code) (652) associated with an advertisement into a unit with a de-coding means (14) which automatically converts the code into CTL (Channel, time and length). The unit within a twen-ty-four-hour-period activates a VCR  (14) to record information on the televi-sion channel (18) at the right time for the proper length of time. The decoded channel, time and length information can be communicated directly to a VCR  (14), and used by the VCR (14) directly to automatically activate the VCR (14) to record a given television information broadcast corresponding to the communicated channel, time and length. Alternately, the channel, time and length information can be decoded directly in a remote control unit (80) and only start record, stop record and channel selection commands (16) sent to the VCR (14) at the appropriate times.  Algorithms for decoding the I codes (652) can be a function of time to ensure security of the decoding method. A method is included for use of the I codes (652) with cable chan-nels.
