  • Patent number: 5737231
    Abstract: An improved metering unit is described which samples a power-related waveform and simultaneously captures its analog signal parameters for temperature and all phases of voltage and current, providing a more accurate and clearer waveform sample that effectively detects harmonics problems and does not require signal interpolation methods. The improved metering unit comprises signal conditioning circuitry interfacing with the power line for sensing temperature and all desired phases of voltage and current parameters of the waveform. The metering unit further comprises a processor having a timer output. The timer output controls track and hold circuitry and an A/D converter. The timer output places the track and hold circuitry in the hold mode to simultaneously capture temperature and all the desired phases of voltage and current of the waveform, and, at the same time, the timer output triggers the A/D converter to convert the captured analog signal parameters into digital sample values.

  • Patent number: 5687504
    Abstract: A manufactured seed is disclosed which comprises a plant embryo preferably encapsulated, or at least in contact with, a hydrated oxygenated gel. The gel can be oxygenated by passing oxygen gas through a gel solution before curing the gel or by exposing the gel to oxygen gas after curing. The gel is preferably oxygenated by adding to an uncured gel solution a suitably stabilized emulsion of a perfluorocarbon compound or a silicone oil, which compounds are capable of absorbing large amounts of oxygen, and are non-toxic and inert. The seed analog can further comprise an outer shell at least partially surrounding the gel and embryo, thereby forming a capsule. The outer shell preferably is shaped to aid the radical of a germinating embryo in protrusively rupturing the capsule, thereby facilitating successful germination and minimizing incidence of seedling malformation. Other shell materials are selected to provide requisite rigidity to the capsule while imparting minimal restriction to successful germination.

  • Patent number: 5672394
    Abstract: A method of preparing electrodes is now described, which electrodes have enhanced adhesion of subsequently applied coatings combined with excellent coating service life. In the method, a substrate metal, such as a valve metal as represented by titanium, is provided with a highly desirable rough surface characteristic for subsequent coating application. This can be achieved by various operations including etching to ensure a roughened surface morphology. In subsequent operations, a barrier layer is provided on the surface of enhanced morphology. This may be achieved by operations including heating, as well as including thermal decomposition of a layer precursor. Subsequent coatings provide enhanced lifetime even in the most rugged commercial environments.

  • Patent number: 5666762
    Abstract: The present invention provides manufactured seeds comprising totipotent plant tissue and a hydrated gel, preferably surrounded by a protective seed coat. The cotyledons of the germinating totipotent plant tissue can be enclosed in a shoot restraint that is resistant to penetration by the growing cotyledons. The manufactured seeds can be prepared for long-term storage, e.g., by sparging the hydrated gel with a respiration-limiting gas before, during, or after assembly of the manufactured seed. The seed is then preferably stored in an atmosphere containing levels of a respiration-limiting gas sufficient to keep respiration of the totipotent plant tissue at reduced levels.

  • Patent number: 5545262
    Abstract: A metal surface is now described having enhanced adhesion of subsequently applied coatings. The substrate metal of the article, such as a valve metal as represented by titanium, is provided with a highly desirable surface characteristic for subsequent coating application. This can be initiated by selection of a metal of desirable metallurgy and heat history, including prior heat treatment to provide surface grain boundaries which may be most readily etched. In subsequent etching operation, the surface is made to exhibit well defined, three dimensional grains with deep grain boundaries. Subsequently applied coatings, by penetrating into the etched intergranular valleys, are desirably locked onto the metal substrate surface and provide enhanced lifetime even in rugged commercial environments.

  • Patent number: 5544304
    Abstract: The present invention provides a method and apparatus for reducing the overhead required in conventional fault tolerant processing by redundant processors. Commands are received and queued by both the active and standby units but are processed only by the active unit. Short messages, each including a command identifier, are transmitted from the active unit to the standby unit. In addition, periodic handshaking signals are exchanged between the two units. In the event the active unit fails, the standby unit is automatically brought on-line to process the unprocessed commands and transmit responses to the command source. When the failed unit is restored, it can become the standby unit.
