Abstract:
A method of enhancing detection signal for measurement of nucleic acid sequences includes providing a T- or L-primary probe having a target-binding segment and an enhancer linker segment; and hybridizing the primary probe with a target sequence of interest; providing a first enhancement probe having a first annealing segment complementary to the enhancer linker segment, a second annealing segment and a chemical label; hybridizing the first enhancement probe to the primary probe; providing a second enhancement probe having a first annealing segment complementary to the second annealing segment of the first enhancement probe, a second annealing segment complementary to the first annealing segment of the first enhancement probe, and the same chemical label; hybridizing the first and second enhancement probes, thereby multiple first and second enhancement probes annealing with each other forming a staggered chain extending from the primary probe; and detecting the chemical labels in the final complex.
Abstract:
A system and method for selectively setting an optical navigation resolution utilizes a comparison of a comparison displacement value to a threshold value to set the optical navigation resolution to an effective resolution selected from a plurality of effective resolutions. The comparison displacement value is based on at least one of a first displacement value in a first direction and a second displacement value in a second direction, which were derived for estimating motion.

A motherboard (100) in accordance with a preferred embodiment includes an audio connection area (10) defining a first jack layout (12). The first jack layout integrates second and third jack layouts for two audio connectors of different specifications, so that jacks (121, 122) of the first jack layout can selectively connect with the audio connectors.
Abstract:
A method and apparatus for activating and dissociating gases involves generating an activated gas with a plasma located in a chamber. A downstream gas input is positioned relative to an output of the chamber to enable the activated gas to facilitate dissociation of a downstream gas introduced by the gas input, wherein the dissociated downstream gas does not substantially interact with an interior surface of the chamber.

Abstract:
A SS7 signalling router receives SS7 signalling regarding narrowband calls to be routed over the ATM network. When the SS7 router receives signalling from the SS7 network, it does not process the signalling, but reads the originator point code (OPC) and forwards the signalling via the ATM network to the ATM switch which is attached to the originator of the message. An interworking function (IWF) at the ATM switch processes the SS7 signalling by generating the appropriate ATM signalling to set up a circuit between the originating ATM switch and the destination ATM switch. The IWF at the originating ATM switch also processes the SS7 signalling by returning it to the SS7 router with the destination point code (DPC) of the PSTN switch coupled to the destination ATM switch. When the SS7 router receives an SS7 signalling message from an ATM switch, it forwards it to the SS7 network where it is sent to the DPC. The IWF at each ATM switch is preferably distributed among several processors including a signalling VSM controller (an SVSM), a plurality of VSM controllers and an ISUP controller. SS7 SUs enter the SVSM controller which separates MSUs from FISUs and LSSUs. The MSUs are sent to the ISUP controller which interrogates the CIC of the IAM messages and forwards the IAM information to the appropriate VSM controller for narrowband to broadband conversion.
Abstract:
The surface of a doped semiconductor wafer is heated locally by means of a pump beam whose intensity is modulated at a first frequency. The heated area is sampled by a probe beam whose intensity is modulated at a second frequency. After the probe beam has been modulated (reflected or transmitted) at the first frequency by the wafer, the modulated probe beam is detected at a frequency equal to the difference between the harmonics of the first and second frequencies to determine dose of the dopants in the wafer. Such or similar type of instrument for measuring dose may be combined with an ellipsometer, reflectometer or polarimeter for measuring dose as well as thickness(es) and/or indices of refraction in a combined instrument for measuring the same sample.
Abstract:
The present invention provides a method and apparatus for preferential PVD conductor fill in an integrated circuit structure. The present invention utilizes a high density plasma for sputter deposition of a conductive layer on a patterned substrate, and a pulsed DC power source capacitively coupled to the substrate to generate an ion current at the surface of the substrate. The ion current prevents sticking of the deposited material to the field areas of the patterned substrate, or etches deposited material from the field areas to eliminate crowning or cusping problems associated with deposition of a conductive material in a trench, hole or via formed on the substrate.
