  • Patent number: 6387636
    Abstract: A method of fabricating an array of biopolymers provides a shield for biochemical reactions and biochemical reactants and is particularly useful for those reactions and reactants that are susceptible to reaction with a component of the ambient environment during the fabrication of the array. The method is applicable to the conventional fabrication and synthesis methods used to fabricate a biopolymer array, such as in situ synthesis of biopolymers on an array and the attachment of pre-synthesized biopolymers on to an array. The method comprises applying a non-miscible fluid (NMF) to the array surface where the biopolymers are being synthesized or attached. The NMF is inert and insoluble with the biochemical reactants and other ancillary materials in solution used in conventional synthesis or attachment of biopolymers.

  • Patent number: 6387736
    Abstract: A structure and a method for providing structural stability at an interface between two poorly adhering layers in a semiconductor device involve providing anchoring channels in one of the poorly adhering layers through which the other poorly adhering layer can be anchored to a third layer. Specifically, the structure and method are applicable to a three-layer stack having a top layer of amorphous silicon, a middle layer of titanium nitride, and a bottom layer of oxide. In order to reduce susceptibility to delamination between the amorphous silicon layer and the titanium nitride layer, the anchoring channels are created in the titanium nitride layer to allow the amorphous silicon to attach to the oxide layer. Because the amorphous silicon layer and the oxide layer exhibit good adhesion between each other, delamination between the amorphous silicon layer and the titanium nitride layer is minimized.

  • Patent number: 6389202
    Abstract: In the fiber and in any fiber (F), a reflecting surface (F1) is created that is generically tilted with respect to the main propagation path (T1) of the optical radiation in said fiber, so as to originate by reflection an additional propagation path (T2) that is generically deflected with respect to said main propagation path (T1). In a mounting support (2) common to the fiber (F) and the related opto-electronic component (O), a groove is made along an external face (2a) so as to accomodate the optical fiber (F) in a tight condition. The groove (3) is then covered through a laminar cover, that is transparent to the radiation and has a flat surface (4a). The fiber (F) is inserted into said groove in order that said deflected propagation path (T2) passes through said cover (4) of material transparent to the radiation, and the opto-electronic component (O) is mounted on said cover (4) in alignment with said deflected propagation path (T2).

  • Patent number: 6389365
    Abstract: A method for operating a spectrum analyzer to provide a marker that follows a peak from sweep to sweep in a spectrum display. The method operates on first and second measured spectrums. The first measured spectrum includes a plot of the signal amplitude against frequency during a first time interval in which the marker has been assigned to a peak at a first frequency and first amplitude. The present invention assigns the marker to a peak in the second spectrum measured during a subsequent time interval in which the marker is to be assigned. Initially, a first frequency range is defined in the second measured spectrum centered on the first frequency. The first frequency range is searched for candidate peaks having amplitudes within a first range centered on the first amplitude. If more than one such candidate peak is found by the search, the marker is assigned to the candidate peak closest to the first frequency.

  • Patent number: 6386050
    Abstract: A system and method for measuring flow rate within a fluid-bearing passageway include introducing heat fluctuations into the flow and then non-invasively monitoring the effects of the heat fluctuations propagating to or from one or more interrogation regions. In one embodiment, the non-invasive monitoring detects fluctuations in the refractive index of the flowing fluid as a result of variations in the temperature of the fluid. In another embodiment, electrical conductivity of the fluid is monitored. The heat fluctuations may be introduced using an optical heat generator, such as an infrared laser, or may be introduced using an electrical member, such as a heater coil. Determining the refractive index along the interrogation region may be achieved by monitoring characteristics on an interference pattern, but other optical arrangements may be utilized.

  • Patent number: 6384760
    Abstract: A multislope, continuously integrating analog-to-digital converter includes a first switch coupled to a first reference voltage, a second switch coupled to a second reference voltage, a third switch coupled to an input voltage, and an integrator operably coupled to the first, second, and third switches. The analog-to-digital converter utilizes a primary discharge current of opposite polarity to a secondary discharge current. The analog-to-digital converter has a high resolution due to a small reference voltage, and a high dynamic range due to a large reference voltage. The analog-to-digital converter can operate in either a conversion mode or a calibration mode. During the calibration mode, a calibration factor is calculated for use during the conversion mode. When applied to the conversion mode, the calibration factor corrects for errors in the conversion process.

  • Patent number: 6384697
    Abstract: A filter formed of acoustic resonators, where each resonator has its own cavity and a bottom electrode that spans the entirety of the cavity, so that the bottom electrode has an unsupported interior region surrounded by supported peripheral regions. In the preferred embodiment, the cavity is formed by etching a depression into the substrate, filling the depression with a sacrificial material, depositing the piezoelectric and electrode layers that define an FBAR or SBAR, and then removing the sacrificial material from the depression. Also in the preferred embodiment, the sacrificial material is removed via release holes that are limited to the periphery of the depression. Preferably, the bottom electrode is the only electrode that spans the cavity, thereby limiting the formation of parasitic FBARs or SBARs. In one embodiment, the bottom electrode includes a serpentine edge that leaves a portion of one side of the cavity free of overlap by the bottom electrode, so that a top electrode may overlap this portion.

  • Patent number: 6378757
    Abstract: Edge mounting flexible media to a rigid PC board construction can be achieved by various methods. In any method used, there is a desire to create solderable pads on the edge of the rigid PC board. In accordance with the invention, the solderable pads are created by edge plating the PC Board or by a sliced via method. Depending on the type of flexible transmission line used, the construction will differ accordingly. For terminating flexible circuit media, the flex pads are laid out in such a way that the pads are etched in a configuration that matches up with the edge pads on the rigid PC Board. Solder past is then applied to the pads on the flex. The rigid PC Board is fixtured at a right angle to the flex and run through the reflow oven.

  • Patent number: 6380819
    Abstract: A tuning method for filters having multiple coupled resonators isolates the characteristics of each resonator, enabling a specified filter response to be achieved by adjusting the resonators according to response criteria. A target frequency response is defined for the filter and a target time domain response is computed based on the target frequency response. From the time domain response, a gating function is generated for each of the resonators. A stimulus signal is provided to the filter and the response to the stimulus signal is measured. The gating functions are then applied to isolate the characteristics of each resonator. Each resonator is adjusted according to response criteria chosen to achieve a specified filter response when the response criteria are satisfied.
