  • Patent number: 8329502
    Abstract: Method of applying a conformal coating to a highly structured substrate and devices made by the disclosed methods are disclosed. An example method includes the deposition of a substantially contiguous layer of a material upon a highly structured surface within a deposition process chamber. The highly structured surface may be associated with a substrate or another layer deposited on a substrate. The method includes depositing a material having an amorphous structure on the highly structured surface at a deposition pressure of equal to or less than about 3 mTorr. The method may also include removing a portion of the amorphous material deposited on selected surfaces and depositing additional amorphous material on the highly structured surface.

  • Publication number: 20120233940
    Abstract: A photovoltaic panel cartridge for mounting a plurality of photovoltaic panels and method of its construction are described. The photovoltaic panel cartridge is formed from a unitary frame with internal beams and struts for stability. The photovoltaic panels are inserted into channels within the frame, struts, and/or the internal beams in order to be mounted to the photovoltaic panel cartridge and secured to mounting regions on a different one of the frame, struts, and/or internal beams. The photovoltaic panel cartridge is configured to be stacked upon similarly configured photovoltaic panel cartridges for ease in transport and to reduce damage to the photovoltaic panels during transport. The photovoltaic panel cartridge may be slidably mounted to rails of a support structure.

  • Publication number: 20120056634
    Abstract: A method of sensing corrosion of a pipe covered by a layer of insulation comprises positioning a CUI sensor radially adjacent an outer surface of the pipe. The CUI sensor comprises a non-conductive base having a first end and a second end opposite the first end. In addition, the CUI sensor comprises a first test circuit mounted to the base. The first test circuit includes a first conductor, a second conductor, and a first testing element extending between the first conductor and the second conductor. Further, the method comprises exposing the first testing element to the same environment as the outer surface of the pipe. Still further, the method comprises determining whether the first testing element has corroded through. Moreover, the method comprises assessing whether corrosion of the pipe has occurred based on the determination of whether the first testing element has corroded through.

  • Publication number: 20070079117
    Abstract: The present invention provides a computer implemented method, system, and computer program product for selective encryption of a data transmission. A data transmission is received. When the data transmission is received, the data transmission is unmarshaled. When the transmission is unmarshaled, objects and a set of sensitive fields within the data transmission are identified by referencing a metadata database. Only the set of sensitive fields within the data transmission are encrypted to form a partially encrypted data transmission. The partially encrypted data transmission is marshaled to form a marshaled data transmission. The marshaled data transmission is transmitted to a recipient.

  • Patent number: 7097310
    Abstract: A ceiling-mounted projection system has a projector mounted above the ceiling, and a periscope assembly that can be moved by a motor along a vertical axis between a raised position in which the periscope assembly is retracted into the ceiling and a lowered position in which the lower portion of the periscope assembly extends below the ceiling. An upper mirror is mounted on the upper portion of the periscope assembly and aligned to reflect images from the projector in a downward direction when the periscope assembly is in the lowered position. A lower mirror is mounted on the lower portion of the periscope assembly and aligned to reflect the images from the upper mirror onto a viewing surface when the periscope assembly is in the lowered position.

  • Publication number: 20060107754
    Abstract: A protection apparatus for a load cell having a constrained end portion and a movable end portion and a load detection apparatus incorporating the same are provided. The protection apparatus includes a housing having a longitudinal axis with a first end and a second end, a pivot disposed through the housing and located in a plane perpendicular to the longitudinal axis of the housing, and a sensor mount pivotally disposed on the pivot. The protection apparatus through its pivot transfers away from the load cell forces that are not aligned with a direction in which the load cell operates. The sensor mount has a first end and a second end, the first end of the sensor mount is disposed in the first end of the housing between a first position and a second position defined by the housing. The second end is configured for attachment to the movable end portion of the load cell. At least one spring is disposed in the second end of the housing for constraining the constrained end portion of the load cell.

  • Publication number: 20050188913
    Abstract: A crystalline material sufficiently pure for use in pharmaceuticals may be made by forming a saturated solution of the material, changing the temperature of the solution so it becomes supersaturated, and subjecting the solution to irradiation by high intensity ultrasound, the frequency of the ultrasound being scanned over a range of frequencies. For example the ultrasound may be varied between 19.5 and 20.5 kHz, and this variation may be sinusoidal. Preferably the ultrasound is provided only briefly, say for less than 5 s, before allowing the solution to cool gradually without further irradiation. The ultrasound may be applied using a vessel with an array of ultrasonic transducers attached to a wall, so each transducer radiates no more than 3 W/cm2 yet the power dissipation within the vessel is between 25 and 150 W/litre. This method can reduce the metastable zone width to less than 10 K. It is applicable in particular to aspartame.

  • Patent number: 5172217
    Abstract: The apparatus and method transforms composite video signals according to NTSC, PAL, or SECAM standards into a symmetrical form in which the chroma component is phase locked to the instantaneous horizontal frequency to provide a fixed chroma phase to horizontal position alignment of video samples for efficient spatial manipulation thereof while preserving the storage efficiency of the single signal composite video format. The horizontally phase-locked symmetrical composite video signal may be transformed back to original asymmetrical chroma-reference based phase modulation for conventional display of the video signals.

  • Patent number: 4233952
    Abstract: A hand catapult for throwing flying discs such as a Frisbee.TM. or a Flying Saucer.TM. is constructed with a yoke pivotally connected to a handle for a movement through an angle of not more than about 45 degrees to each side of the center line of the device. The yoke comprises an inner circumferentially channeled semicircular portion conforming to and adapted to receive the disc and having a long complementarily channeled arm projecting tangentially from one terminus of the semicircular portion and a short complementarily channeled arm projecting from the other terminus of the semicircular portion. The yoke is constructed of semirigid plastic material and the short arm extends beyond the semicircular portion a distance just sufficient to offer a slight resistance to the insertion and withdrawal of the disc in the channeled semicircular portion. The device is biased to the uncocked position and is provided with a pressure-releasable device for holding the yoke in the cocked position against said bias device.
