摘要:
An array is formed with a protective cover on a substrate. The protective cover is patterned to produce an array of openings to the substrate. Desired material is deposited on the substrate through the openings. The protective cover may then be removed. In one embodiment, the protective cover is a conformal polymer, such as di-para-xylylene. It may be removed by mechanical peeling. The material may be biological material such as DNA. The protective cover may be used to prevent non-specific hybridization in inter-spot regions by performing hybridization with the cover still in place. Hybridization that occurs in such regions between the spots may be removed with removal of the protective cover.

A high power RF IC capable of impeding parasitic current loss and method of manufacturing the same. First a step of semiconductor front-side processing for the high power RF components that includes inductive components is performed. Afterwards, the backside of semiconductor base is polished to a certain thickness, and then lithography and etching processes is employed for forming a backside trench contact window. A backside deposition for oxide insulation layer can be performed so that the oxide insulation layer can be located in the semiconductor base right under the inductive components for impeding the parasitic current loss generated by the inductive components in the semiconductor base due to electromagnetic induction. Therefore, performance of the inductive components operating in high frequency can be improved.

A system and method for controlling access to parameter blocks of a sound processor. According to the method and system disclosed herein, the present invention includes a host, a sound processor coupled to the host, and at least two copies of a parameter block associated with the sound data. The sound processor can access a first copy of the at least two copies while the host is accessing a second copy of the at least two copies. As a result, parameter blocks are freely updated by the host processor and freely read by the sound processor without conflict and without performance loss.

The invention provides methods and compositions for normalizing and amplifying RNA populations. The methods generally comprise the steps of copying message RNA (mRNA) to form first single-stranded (ss) cDNA; converting the first ss-cDNA to first double-stranded (ds) cDNA; linearly amplifying the first ds-cDNA to form first amplified RNA (aRNA); tagging the 3′ end of the first aRNA with a known sequence to form 3′-tagged first aRNA; copying the 3′-tagged first aRNA to form second ss-cDNA; and normalizing the mRNA and/or the first aRNA.

An exemplary embodiment relates to a method of pinhole decoration and detection. The method can include providing a material layer above an amorphous carbon layer where the material layer has a pinhole, providing a film over the material layer where the film has a substantially planar surface except above the pinhole, and detecting the pinhole by detecting a non-planar location on the substantially planar surface of the film.

Nucleic acids are made by converting a primed single-stranded DNA to a double-stranded DNA by a method comprising the step contacting the single-stranded DNA with a DNA polymerase having 5′ exonuclease activity under conditions whereby the DNA polymerase converts the-single stranded DNA to the double-stranded DNA, wherein the single-stranded DNA is primed with oligonucleotide primer comprising a sequence complementary to the 3′ end of the single-stranded DNA, and at least one of the 5′ end of the primer and the single-stranded DNA comprises an RNA polymerase promoter joined to an upstream (5′) flanking moiety which protects the promoter from the 5′ exonuclease activity of the DNA polymerase.

A hip exerciser includes a main stand, a front bracket and a rear bracket both pivotally connected to the main stand, at least one resilient member mounted between the front bracket and the rear bracket, a supporting bracket securely mounted on the main stand, a seat pivotally connected to the front bracket, and a backrest pivotally connected to the rear bracket. The hip exerciser further includes an extendable stand moveably extending from the main stand and controlled by a knob. Two shaft are pivotally connected with the extendable stand and two pedals are pivotally connected to free ends of the shaft. When a user sits on the seat and leans on the backrest to pivot the backrest, the front bracket and the rear bracket are also pivoted thus extending the resilient member to provide a resistance force, whereby hips of the user are exercised.
摘要:
A process for manufacturing easily portable and multi-layered adhesive tape roll is described. The flat piece of easily portable and multi-layered adhesive tape is formed by compressing the adhesive tape roll having circular shape or other shapes. The adhesive tape roll is compressed and cohered during the compressing step. A stiff interfacial layer, for example, having adhesion by adhering two innermost adhesive surfaces, by providing a stronger adhesion material, by inserting a stiff and solid material, or a stiff and solid material coated with a strong adhesion material, is applied to the symmetry plane of the adhesive tape during the compressing step. The preferential material of the high adhesion material is a cyanoacrylate adhesive or an epoxy adhesive.
摘要:
For data transmission in a digital mobile communication system, in a mobile communication system employing a so-called multi-channel access technique, one or more traffic channels may be allocated to a mobile station for data transfer, in accordance with the data transfer rate required by the application using the mobile station. Minimum and maximum requirements are determined for the data transfer rate of the user data. The mobile communication network dynamically adjusts the channel configuration assignment to the mobile station for the data call, so as to consist of one or more traffic channels, within the limits of the minimum and maximum requirements of the data transfer rate, depending on the changing allocation state of the resources of the mobile communication network.
