  • Patent number: 7397036
    Abstract: Apparatus and method for measuring the fluorescence of nanodrop liquid samples is described in which the sample is held by surface tension between two anvil surfaces. Each anvil surface has an embedded optical fiber with its end finished flush with the surface in the containment area wetted by the sample with the fiber in line. Sample excitation is provided from the side of the sample remote from the containment area. By selection of the fiber transmission numeric aperture the impact of exciting and ambient light on the measurement is minimized. A method of virtual filtering is taught in which any ambient or exciting light that does impinge on the measuring sensor is corrected by subtracting a scaled representation of the source from the measurement. The method and apparatus is capable of detecting 1 femptomole of sodium fluorescein in 1 microliter of TE buffer.

  • Publication number: 20070047088
    Abstract: A sensing method and apparatus using photonic band gap multilayered material. Photonic band gap multi-layers are formed from alternating layers of higher refractive index and lower refractive index materials, and may be deposited or disposed on a optically transparent substrate or a reflecting face of a prism. Light is directed into the prism, directed to the photonic band gap multilayer, and reflected out of the prism, where it is captured and analyzed. Various sensor configurations keep light wavelength or coupling angle fixed, while monitoring the change in the other parameter. Also disclosed is a microarray configuration with an array of probe spots placed on one surface of the multilayer, which is mounted on an x-y translation stage.

  • Publication number: 20060230423
    Abstract: An apparatus for calibrating test equipment at a CATV service organization or customer site includes a calibration unit for calibrating a signal level measurement circuit that is operable to generate signal level measurements for a set of broadband RF signals and an access monitor for enabling operation of the calibration unit in response to a token indicative of calibration credits being coupled to the access monitor. The access monitor may also include a port for receiving a token containing calibration credit data. The port may be a USB port, a smart card reader, or a keypad, for example. A memory fob received in the USB port may be interrogated for calibration credit data that are used to enable a calibration procedure and a smart card may be received in the smart card reader for similar purposes. The keypad may be used to enter a password and account data associated with the password may be read and evaluated to determine whether a requested calibration procedure may be performed.

  • Patent number: 6401731
    Abstract: The decontamination of PCB-containing transformers to obtain treated transformers containing less than 50 parts per million (ppm) polychlorinated biphenyls (PCB) can be achieved using a method wherein the transformer is initially drained of all PCBs; then the core/coil assembly is removed. The internal surfaces of the transformer are then cleaned using a solvent. Finally, a new core/coil assembly is installed. The method is simple and can be completed within a substantially shorter period of time than methods known in the art.
