  • Patent number: 5972188
    Abstract: An apparatus and method for loading samples into a gel of an electrophoretic gel system (EGS). The preferred sample loader includes a membrane having a net negative charge, net neutral charge or no charge (preferably nitrocellulose or nylon) which releasably retains the samples such that the samples are actively released when the membrane is inserted into the gel of an EGS. In one preferred embodiment, the sample loader includes a substrate having a plurality of sample loading areas extending therefrom. In an alternative embodiment, the membrane is substantially thick and serves as its own substrate. In another embodiment, sample inhibiting agents such as hydrophobic ink are formed through the membrane to inhibit the diffusion of samples between sample loading areas. Each sample loading area includes an affixed membrane. In use, one or more samples to be subjected to electrophoretic action are applied to the membrane before the membrane is inserted into a previously polymerized gel.

  • Patent number: 5862391
    Abstract: The power management control system comprises a computer having standard RS485 interface cards and adapters installed in its I/O slots defining multiple industry standard Modbus RTU networks. The computer contains software for monitoring and controlling selected aspects of power usage/consumption, as described in more detail hereinafter. The Modbus RTU protocol is a well known industry standard. Devices with a Modbus RTU interface can be connected directly to the Modbus and other devices which communicate on the Commnet protocol require a Modbus concentrator. The Modbus concentrator provides an interface between the Modbus RTU protocol and the Commnet protocol, whereby these other devices can communicate through the Modbus concentrator over the Modbus. Alternatively, standard Ethernet interface cards and adapters are installed in the computer's I/O slots defining multiple standard Ethernet TCP/IP networks.

  • Patent number: 5825498
    Abstract: Disclosed is a process for analyzing the surface characteristics of opaque materials. The method comprises in one embodiment the use of a UV reflectometer to build a calibration matrix of data from a set of control samples and correlating a desired surface characteristic such as roughness or surface area to the set of reflectances of the control samples. The UV reflectometer is then used to measure the reflectances of a test sample of unknown surface characteristics. Reflectances are taken at a variety of wavelengths, preferably between about 250 nanometers to about 400 nanometers. These reflectances are then compared against the reflectances of the calibration matrix in order to correlate the closest data in the calibration matrix. By so doing, a variety of information is thereby concluded, due to the broad spectrum of wavelengths used.

  • Patent number: 5783804
    Abstract: A nondestructive product level calibration method which is based on reflectance of intensity of UV and visible light that is measured from the top surface of a semiconductor wafer in a RTP closed loop process control environment in which the temperature of the wafer is regulated as a function of reflectivity of radiation at a preselected wavelength from the top surface of the wafer. In the method, sheet resistance of the wafer is measured as a function of the intensity of the UV and IR light directed at the wafer over a predetermined temperature and time range. Then, the reflectance intensity off wafer is measured to develop a model of the top surface. The reflectance model will indicate a wavelength where the reflectance is the greatest. Next, the wafer is subjected to UV radiation at the most sensitive wavelength and the reflectance is plotted against intensity of heat treatment.

  • Patent number: 5764155
    Abstract: A dynamic data exchange (DDE) server which allows external programs to access power management data is presented. The DDE server provides a mnemonic cross reference between register items and standardized, alphanumeric parameter names. This mnemonic interface allows the user to retrieve data from a device without knowledge of the actual device register item number. Also, the DDE server automatically performs time synchronizing for all supported devices and provides a consistent waveform and event interface. The DDE server is optimized for either the Modbus RTU or Ethernet protocol. The DDE server includes toolkit functions which are used to maintain DDE communication and protocol timers and to maintain active topic and item lists. The DDE server acts as a link between a client requesting device data and a field device which can provide the data. The DDE server communicates to the field device through communication ports and to the client via DDE message link.
