A storage-and-forward apparatus accommodates a plurality of private lines and a plurality of public lines. The storage-and-forward apparatus includes an exchange for carrying out a connection and a disconnection between each of the private lines and each of the second lines, and an image memory for storing image information transmitted via each of the private lines from a facsimile. The storage-and-forward apparatus directly relays image information transmitted via each of the private lines from...

An intraluminal imaging catheter system for viewing segments of vessels downstream of the catheter itself is provided. The catheter system incorporates an ultrasonic transducer pivotally mounted adjacent the catheter's distal end. A flexible drive means disposed within a flexible tubular member adapted for insertion into the vessel causes the transducer to pivot back and forth to scan a segment of the vessel. Optionally, the forward viewing catheter system of the present invention may be combine...

A Forward Feed Neural Network is disclosed using data flow techniques on a data flow microprocessor. As a result of this invention, a neural network is provided that has the capacity of "learning" to distinguish among patterns of data which may differ recognizably from idealized cases, and is able to perform pattern recognition faster while utilizing less memory and fewer clock cycles than neural networks implemented on sequential processors. This implementation is simpler and faster because of ...

In a feed forward amplifier (100), a main amplifier (125) is coupled between an input (102) at which an input signal is received and an output (173) at which an output signal is provided. The output signal is an amplification of the input signal. A sample of the output signal is compared (144) with a sample of the input signal to produce a difference signal indicative of distortions introduced by the main amplifier (125). An error amplifier (165) provides a distortion signal which is an amplific...

The present invention relates to a forward/backward counting device intended for providing an absolute address of N bits in binary code, the address enabling the position of an object to be deduced from two signals leaving a non-absolute position coder linked to the object. A device generates a first partial address expressed in code which differs from the binary code. A microprocessor is linked to the device and enables the first partial address to be transformed into an absolute address. The i...

A tumble forward seat having mounting brackets that are rigidly attachable to a motor vehicle body and which establish a pivot axis for the seat frame. The brackets are releasably attached to a pair of front mounting pins in the vehicle body floor to hold the brackets stationary in the vehicle. The seat assembly frame then pivots about the mounting brackets from a generally horizontal use position to a tumble forward stowed position to increase the cargo capacity of the vehicle. When rotated for...

A store and hold communications system for storing data files and associated notification messages created at a plurality of first locations. The data files and associated notification messages are automatically and selectively transmitted and stored in remote data stores at a remote location. The remote data stores are associated with a plurality of second locations. Facsimile copies of the notification messages are automatically sent to selected second locations corresponding to the intended r...

In a feed forward amplifier, an RF amplifier is supplied with an input RF signal at an input terminal for amplifying the same; a distortion extraction loop supplied with the input RF signal and further with the output RF signal from the RF amplifier is for extracting non-linear distortion components formed in the output RF signal as a result of amplification in the RF amplifier; a variable phase shifter is provided in the distortion extraction loop for varying a phase of the input RF signal; a v...

There is disclosed an improved lawnmowing and edging apparatus wherein a generally conventional gasoline powered push mower or walk-behind mower is provided with an edger mounted on the front of the deck of the mower slightly outside of the track of one of the front wheels, the edger having a high speed rotating blade which lies in a vertical plane and which can be raised to an inoperative position or lowered to an operative position. The edger is provided with a very simple belt and pulley driv...

The present invention is a feed forward circuit and method for reducing distortion added to an output signal of the feed forward by its amplifiers without increasing the time delay in the main circuit path of the feed forward circuit. This is accomplished using a pre-distortion circuit to introduce a pre-distortion signal to the input signal of a correction amplifier. The pre-distortion signal is being used to cancel a distortion signal that will be introduced by the correction amplifier. The pr...
