  • Patent number: 7362609
    Abstract: A one-transistor (1T) NVRAM cell that utilizes silicon carbide (SiC) to provide both isolation of non equilibrium charge, and fast and non destructive charging/discharging. To enable sensing of controlled resistance (and many memory levels) rather than capacitance, the cell incorporates a memory transistor that can be implemented in either silicon or Sic. The 1T cell has diode isolation to enable implementation of the architectures used in the present flash memories, and in particular the NOR and the NAND arrays. The 1T cell with diode isolation is not limited to SiC diodes. The fabrication method includes the step of forming a nitrided silicon oxide gate on the Sic substrate and subsequently carrying out the ion implantation and then finishing the formation of a self aligned MOSFET.

  • Patent number: 6218378
    Abstract: A method of treatment or inhibition of tumors including the steps of: (i) exchanging one or more of the eight phenyl substituents in the compound [M(dppe)2]+ where M is selected from Au(I), Ag(I) and Cu(I) by 2, 3, or 4 pyridyl substituents to provide a compound having anti-tumor activity and an octanol/water partition coefficient between 0.01 and 25.5; and (ii) administering said compound to a subject requiring treatment which compound has selective toxicity to cancer cells including cisplatin resistant human carcinoma cell lines.

  • Patent number: 6034638
    Abstract: In one embodiment, an antenna has four equally spaced monopole elements mounted in a symmetric array on the outer surface of a solid cylinder structure. The cylinder has a high dielectric constant, and extends from a conductive ground plane. The monopole elements can be switched by switching elements so that one or more is active, with the others acting as parasitic directors/reflectors being connected commonly to ground or left in an open circuit condition to be effectively transparent.

  • Patent number: 5688647
    Abstract: A method detects whether an individual is predisposed to obesity. The method includes the steps of (i) obtaining a sample containing human genomic DNA from the individual; (ii) detecting whether the genomic DNA in the sample has a 7 AT tandem repeat in exon 18 of the low density lipoprotein receptor gene on one or both chromosomes; and (iii) correlating the absence of the 7 AT tandem repeat on the chromosome or chromosomes with a predisposition to obesity in the individual.

  • Patent number: 5284749
    Abstract: Assay for detection of a form of diamine oxidase which is present only in amniotic fluid and, more especially, for detection of amniotic membrane rupture by detection of the amniotic fluid diamine oxidase. The assay includes the steps of detecting the amniotic fluid diamine oxidase and distinguishing that from another form of diamine oxidase found in serum. The assay may be carried out on a sample of vaginal fluid from a pregnant female wherein the sample is subjected to the assay to detect the leakage or presence of amniotic fluid diamine oxidase. Purified forms of amniotic fluid diamine oxidase and serum diamine oxidase which is different from amniotic fluid diamine oxidase and found in serum are also described, together with a method of purifying both forms of diamine oxidase.

  • Patent number: 5227485
    Abstract: The A21 receptor extracelluar site and the A2 receptor extracellular site of adenosine analogues are structurally different and that binding orientations of adenosine or adenosine analogues are different at these sites and this may be used to determine their structure. Novel pyrimidine compounds are described.

  • Patent number: 4682118
    Abstract: A PSK and phase modulation transmission system has a modulator and a demodulator. The modulator has a carrier frequency generator (21) coupled to a voltage controlled phase shifter (22). The modulation of the signal in the shifter (22) is controlled by modulation voltage generator (23). A transmitter (24) receives the output from the shifter (22) and transmits the modulated signal. The demodulator (30) includes a receiver section (31) for receiving the signal transmitted by the transmitter (24). The receiver (31) is coupled to a modified phase locked loop comprising a phase detector (32), a low pass filter (33), a sample and a hold circuit (34) and a voltage controlled oscillator (35). A lock control circuit (36) receives either the output from the receiver (31) or the output from the filter (33) to produce a lock in pulse from changes in the received signal or changes in the demodulated signal at the filter (33) for controlling the sample and hold circuit (34).
