摘要:
An apparatus comprising a rack having one or more shelves, a plurality of electronics circuit boards and heat conduits and a cooler. Each board is held by one of the one or more shelves, some of the boards having a localized heat source thereon. Each heat conduit forms a heat conducting path over and adjacent to a particular one of the boards from a region adjacent to the heat source thereon to a connection zone, the zone being remote from the heat source. The cooler is located on a side of the rack and coupled to the zones such that heat is transferable from the paths to the cooler. The cooler is configured to flow a cooling fluid therein to cool localized thermal interfaces at the cooler, each interface being adjacent to and at a corresponding one of the zones.

An apparatus includes a reservoir to hold a volume of liquid, a port to inject a flow of gas into a lower portion of the reservoir, and a structure to transform the flow of gas into one or more streams of bubbles in said liquid. The reservoir has a port for injecting the gas into a lower region of the volume of liquid and has a top opening to release the injected gas therefrom. The apparatus includes one or more active electronic or optical devices located in the reservoir or located physically adjacent and in thermal contact with the reservoir such that the volume of the liquid is able to absorb part of heat produced by the one of more electronic or optical devices.

Hot fill and retort stable containers can be made by blowmolding parisons made with polyalkylene terephthalate and a sufficient amount of nucleating agent under conditions that include heated molds, directional cooling air on container stress areas from vents formed into a push rod that is extended into the molded container while still in the heated mold, and an adequate residence time to grow the desired degree of crystallinity.

A communication device locates a preferable wireless service provider in a multi-service provider environment using a frequency band search schedule. Initially, the communications device registers with a less preferred service provider in a first frequency band. While remaining registered with the less preferred service provider, the device examines several frequency bands in the order specified by the frequency band search schedule. A frequency band is examined by dividing the frequency band into many sub-bands, and by locating the strongest signal above a threshold within the sub-band being examined. The examination continues until a second frequency band having a more preferred service provider is located. The communication device then registers with the more preferred service provider. The category of service provider may be identified and displayed on the communication device.

摘要:
This device employs a visible laser module that will typically be a laser diode with an output beam mechanically aligned to the GoPro camera lens and its FOV (Field of View). This device is small and lightweight and can either be built into any part of the GoPro assembly or can be attached to part of the camera assembly. The housing includes the laser module, On/Off switch, batteries, tilt switch, and the required electrical interconnections.

The present invention relates generally to constructs and their use in gene expression or gene regulation assays. More particularly, the present invention provides expression vectors and/or reporter vectors providing kinetics of protein expression with improved temporal correlation to promoter activity. Even more particularly, the invention provides expression vectors comprising a transcribable polynucleotide which comprises a sequence of nucleotides encoding a RNA element that modulates the stability of a transcript corresponding to the transcribable polynucleotide. The present invention provides, inter alia, novel vectors, useful for identifying and analysing cis- and trans-acting regulatory sequences/factors as well as vectors and genetically modified cell lines or organisms that are particularly useful for drug screening and drug discovery.
