摘要:
A method of probing a plurality of analyzer molecules distributed about a detection platform is disclosed. The method includes contacting a test sample to the plurality of analyzer molecules, scanning the plurality of analyzer molecules at a rate relating to a carrier frequency signal, and detecting the presence or absence of a biological molecule based at least in part upon the presence or absence of a signal substantially at a sideband of the carrier frequency signal. A molecule detection platform including a substrate and a plurality of targets positioned about the substrate is also disclosed. Specific analyzer molecules adapted to bind a specific analyte are immobilized about a first set of the targets. Nonspecific analyzer molecules are immobilized about a second set of the targets. The targets positioned about the substrate along at least a segment of a scanning pathway alternate between at least one of the first set and at least one of the second set. A method including providing a substrate for supporting biological analyzer molecules the substrate including at least one scanning pathway is also disclosed. The scanning pathway includes a plurality of scanning targets. Specific biological analyzer molecules adapted to detect a specific target analyte are distributed about a first set of the targets which alternate in groups of at least one with a second set of the targets the second set of the targets not including the specific biological analyzer molecules.

An antenna device is provided, which includes a first antenna unit and a second antenna unit. The first antenna unit includes a first radiation module, a power divider/combiner network connected to the first radiation module, and a feeder interface connected to the power divider/combiner network. The feeder interface is connected to a radio remote unit (RRU) or a macro base station through a feeder. The second antenna unit includes a second radiation module, a transceiver array connected to the second radiation module, a baseband processing unit (BPU) connected to the transceiver array, and an optical fiber interface connected to the BPU. The optical fiber interface is connected to a baseband unit (BBU) through an optical fiber. Therefore, after the existing passive antenna is replaced by the provided antenna device, the RRU or macro base station in the original network can still be used, which reduces waste of resources.

A method for providing a magnetic recording transducer is disclosed. The method includes providing a first pole having front and rear portions and a back gap on the rear portion. The method also includes providing an insulator on the first pole. The method includes providing a write gap and providing a portion of a second pole on at least the write gap. A portion of the write gap resides on the front portion of the first pole. A portion of the insulator covers a portion of the first pole between the portion of the second pole and the back gap. The method also includes providing a mask that covers the back gap and exposes the portion of the second pole and the insulator. The method also includes performing a pole trim that can substantially remove the portion of the insulator covering the remaining portion of the first pole.

The system includes a plurality of Mobile Stations (MSs); at least one distributed antenna having the ability to perform simultaneous communications with the plurality of MSs; and a base station connected to the at least one distributed antenna through optical fibers for performing communications and handovers with the multiple MSs.
摘要:
Method and apparatus for use with a probe beam and detector for detecting the presence of a target analyte in a sample. The apparatus includes a substrate; and a biolayer located on the substrate designed to react to target analyte when the sample is deposited on the biolayer. The substrate can be selected to substantially minimize reflectance by the substrate while substantially maintaining scattering by the target analyte. The substrate can be designed so waves reflected by the substrate are substantially in quadrature with waves scattered by target analyte; or so waves reflected by the substrate and scattered by target analyte interfere in the far field and directly create intensity modulation detectable by the detector. The biolayer can include a plurality of spots, and the spots can be grouped into unit cells having specific antibodies and non-specific antibodies for reacting with target analyte.
