Patent EP-0703662-A2 (EP)
Inventor: WEAVER BRYAN ALEXANDER
IPC: H03F3/24
Filed: 1991-06-04
Abstract: A power amplifier for a plate load of an AM, RF transmitter includes plural switching stages each powered by a DC source. Each stage is switched from non-sourced to saturation in response to the amplitude of a source exceeding a threshold amplitude for the stage; each stage has a different threshold. The thresholds and source are arranged so that responses derived between output terminals of the stages change between zero and predetermined amplitudes as the source amplitude changes relative to the thresholds of the different stages. The responses of the different stages are summed. A triangular wave having a small constant maximum amplitude relative to the source maximum value effectively changes the threshold of each stage. From time to time the thresholds of different stages are changed so that at different times different stages are in non-sourced and conducting for the same amplitude of the modulating source, while providing the same summed response for the same amplitude of the modulating source.

Filed: 1996-06-10
Abstract: The method involves transmitting data which is encoded by multi-component coding. Important bits or bit sequences are selected from an information sequence. The remaining component coders receive the bit sequences until an uneven error protection level is achieved. The selection algorithm for the important bits can be changed according to different commands. The selected bits or bit sequences are transmitted via interleaving devices. Single parity check codes can be used as further component codes. A variable number of coder symbols is generated from the code sequences and inserted into the code stream according to variable conditions, e.g. quality of the transmission channel.

Abstract: There is described a recording method of a digital magnetic recording medium for a copyright protection and a variable speed playback when a user records a digital broadcasting program by a digital video cassette recorder (DVCR) or variable speed playback of a rental tape while performing a copyright protection function, a video track of a video tape is separated into a scrambling data region where scrambling data is recorded and a descrambling region where descrambling information for descrambing the scrambling data is recorded to record the video data on the corresponding region. When this method is adopted with a proper copyright protection system, the copyright of the program provider can be protected, and the lowering of the performance is also minimized during the user's variable speed playback of the video tape to which the copyright protection function is adopted, thereby satisfying both the program provider and the user.

A bit line contact 20 occurs at the apex of the moat and storage node contacts 22, 24 occur at the ends of legs 40, 42 extending from the apex. The wavy bit lines have alternating crests 32, 36 and troughs 34, 38. The bit lines are arranged over the moats with the troughs of each bit line overlying and contacting the apexes of each moat and the crests avoiding any moat. The crests and troughs of the bit lines are offset from one another. In a half-pitch pattern, the troughs of one bit line lie adjacent to the crests of the next bit line. The moats are concave between the legs and the angle between the legs is between about 140 and 170 degrees. The angle between the crests and troughs of the bit lines is between about 110 and 160 degrees. In one embodiment, the central portion 70 between the areas surrounding the storage node contacts is about 10% wider than the areas surrounding the storage node contacts.

Abstract: The invention relates to methods for the identification of metastatic sequences. Cells from a cell line or an animal tissue are treated to form a cell line predisposed to metastasis. Treated cells are implanted in an animal of a primary site and incubated for a period of time sufficient for the cells to proliferate and develop metastases at secondary sites. Expressed sequences from cells at the primary and secondary sites are amplified by differential display polymerase chain reaction and compared. Differentially expressed sequences are identical and can be cloned and sequenced. These sequences can be used as probes in the diagnosis of metastatic disorders, as probes to isolate metastatic sequences and as a therapeutic agent.

Abstract: The invention is related to a method for converting a series of drawing instructions suitable for assigning pixel values corresponding to said drawing instructions to pixels positioned in an image arranged in rows and columns of pixels, to a series of runlengths and corresponding pixel values. A runlength hereby represents the number of successive pixels with mutual identical pixel values while the series of runlengths and pixel values is arranged according to a first order as determined by successive pixel positions. First the runlengths of the pixel values as generated by the drawing instructions are determined in a second order which is different from the first order. Consequently, the insert positions of said determined runlengths are determined on the basis of pixel positions which are corresponding with said determined runlengths. On the basis of these insert positions, said deteremined runlengths are inserted in the series of runlengths according to an prescription for inserting whereby runlengths in the series which have positions in common with said runlengths to be inserted, are modified in dependance on the said runlengths and pixel values to be inserted.

Abstract: The present invention provides a system and method for compressing a data sequence comprising a plurality of records, each record having a plurality of fields and each field being arranged to contain a data item. The system comprises: comparison means which, for a current field within a current record other than the first record in the data sequence, is arranged to compare the data item in the current field with the data item in the corresponding field of a preceding record; and match indication means, responsive to a signal from the comparison means indicating that the data item matches the data item in the corresponding field, for replacing the current field data item by a token indicating the match. The comparison means is arranged to repetitively perform the comparison process on a predetermined number of fields in a plurality of records of the data sequence. Preferably the system is incorporated within a server computer, the server being arranged to output the data records of the data sequence as compressed by the system for transfer over a network to a client computer. 
     The technique of the present invention is a very quick algorithm, taking very little resource. It does not prevent the use of more traditional compression techniques, and is simple. Further, it recognises the field structure of the data and uses this as a method to achieve good compression. Its algorithm is not affected by the host computer architecture nor that of the transport layers. Additionally, it can reduce the CPU resources required at the client side, thereby improving performance above and beyond the data reductions.

Abstract: A combination dilatation and drug delivery device
includes a flexible catheter (18,90), a drug delivery
sheath (20,92) mounted to a distal end region of the
catheter and a dilatation balloon (24) or other
dilatation device (104) mounted to the catheter and
contained within a compartment (52,100) formed by the
sheath. The sheath is radially expandable by supplying a
liquid therapeutic agent to the compartment under a
moderate pressure. The dilatation balloon is expandable
by providing a dilatation fluid to the balloon under a
much higher pressure. The sheath can be formed of a
highly elastic material or can be made quite thin, and in
either case is mounted independently of the dilatation
device. Thus when radially expanded, the sheath is moved
into a conforming contact with surrounding vascular
tissue. The conforming contact protects tissue and the
therapeutic agent from exposure to blood, and more
effectively confines the therapeutic agent to the
intended treatment area. The sheath either is naturally
porous or is provided with multiple pores, whereby the
therapeutic agent perfuses through the sheath into the
surrounding tissue.
