Embodiments of methods and apparatuses for removing ghosts from a signal such as a communications signal received over a channel where the output symbol pattern is used for selecting correction factors for correcting the received symbols. The correction factor is added to the sampled symbols and the sampled symbol is compared with a selected one of a plurality of thresholds based upon the closeness of the various thresholds to a sequence of the corrected symbol values. That comparison forms the ...

A concept for providing navigation information is described. The concept includes a process for providing navigation information including deriving a destination for a first vehicle and determining a present location of the first vehicle. The process also includes computing maneuvering information from the destination and present location and adapting an image of a ghost vehicle in conformance with the maneuvering information.

A ghost canceller includes a ghost canceling circuit having a transversal filter for receiving a television input signal and a tap gain holding circuit for holding tap gains of the filter, a ghost detector, and a means for writing tap gain data into the tap gain data holding circuit in response to the ghost detector to permit a ghost component in an output signal of the ghost canceling circuit to be canceled out. In order to prevent the disturbance of a TV screen due to a transient response whic...

An apparatus and a method for storing diagnostic software on a data storage device provides one or more ghost partitions overlapping a user partition on a data storage device. During a factory download of the application software as well as the diagnostics software, the apparatus creates a user partition and one or more overlapping ghost partitions. Next, it determines a minimum and maximum partition size for the ghost partition(s) and allocates the ghost partition size(s) appropriately. The app...

A ghost canceller includes a ghost cancelling circuit, waveform memories, a CPU, a training signal generating circuit, and a ghost variation detection circuit. By taking in GCR signals from the waveform memories into the CPU, synchronous addition and field sequence processing are effected, and they are transferred to the training signal generating circuit. The input video signal is changed over to the training signal to cancel ghosts, and when ghost variations are is not detected by the ghost va...

A ghost canceller which operates at IF and utilizes a storage mode heterojunction acoustic charge transport device (SM-HACT). The signal delay provided by the SM-HACT is increased by the operation of barrier electrodes which delay the movement of charge packets across the device, thereby eliminating the need for additional digital equalization. The tap weights of the SM-HACT are determined by the operation of a fixed correlator which responds to ghosts in a predetermined training waveform.

A ghost canceller for the cancellation of a ghost signal from a complex electrical signal including a desired signal component as well as the ghost is provided wherein an electronically variable delay line of the charge transfer type is incorporated in a negative feedback loop. Bucket-brigade and charge-coupled devices may be employed with associated variable frequency clock oscillators to provide remotely variable delay times in an easily implemented structure.

A foot ghost ender comprised of a rounded steel shell having a front, a back, a left sidewall, a right sidewall, an open top, a closed bottom, an inner surface, and an outer surface. An aperture is formed in the right sidewall. An extension is integral with the open top. The extension has an open circular top. A plurality of tanning lamps are secured to the inner surface of the rounded steel shell. An adjustable foot rest is secured to the inner surface of the rounded steel shell. The device als...

A ghost cancelling system has a transversal filter connected to a video signal source to produce a ghost cancelling signal, composed with a video signal from the video signal source by use of a composer. A circuit is provided for detecting a ghost level during a predetermined period, including a masking pulse forming circuit and a detecting circuit for detecting a reference time point, a circuit for forming a standard waveform from the output of the detecting circuit, a circuit for subtracting t...

A ghost signal cancellation system for cancelling ghost signals caused, for example, by reflection in a transmission line of television signals transmitted from a television transmitting station. This system is particularly suited for incorporation in a television receiver to improve the picture quality of a reproduced picture.
