摘要:
A method and sensing apparatus for elevators that detects an intrusion into a volume defined relative to a path across an opening. The sensing apparatus has a closure member for the opening that can be controllably displaced to define a gap in the opening. A first group of at least two emitters of electromagnetic signals located on either the closure member or a boundary member are directed into the volume and a second group of at least two receivers for electromagnetic signals located on the opposite side of the gap to the emitters. The method causes at least one of the emitters to emit a primary beam along a first axis into the volume, allows at least one of the receivers to receive a secondary beam of radiation, and enables one or more of the receivers to provide an output signal into the network.

摘要:
A system and method for validating adherence of an UII identifier code to one of several prescribed DOD codes by means of a programmed series of tests. First the code is tested for a prescribed header and a last character message. If one or the other is not found, the process stops and an error message is displayed. Field separator characters are identified that divide the message into fields. If the header, end of message character, and field separator are found and tested successfully, the program proceeds, and searches for an identifier of one of the DOD prescribed semantic formats. The semantic format identifier is extracted and tested. If valid, the process proceeds. If not, an error message is displayed. In proceeding, each field is stored, and the data from each field is extracted in accordance with the format identifier that had been extracted.
摘要:
Chimeric human-bovine respiratory syncytial virus (RSV) are infectious and attenuated in humans and other mammals and useful in vaccine formulations for eliciting an anti-RSV immune response. Also provided are isolated polynucleotide molecules and vectors incorporating a chimeric RSV genome or antigenome which includes a partial or complete human or bovine RSV “background” genome or antigenome combined or integrated with one or more heterologous gene(s) or genome segment(s) of a different RSV strain. Chimeric human-bovine RSV of the invention include a partial or complete “background” RSV genome or antigenome derived from or patterned after a human or bovine RSV strain or subgroup virus combined with one or more heterologous gene(s) or genome segment(s) of a different RSV strain or subgroup virus to form the human-bovine chimeric RSV genome or antigenome. In preferred aspects of the invention, chimeric RSV incorporate a partial or complete bovine RSV background genome or antigenome combined with one or more heterologous gene(s) or genome segment(s) from a human RSV. Genes of interest include any of the NS1, NS2, N, P, M, SH, M2(ORF1), M2(ORF2), L, F or G genes or a genome segment including a protein or portion thereof. A variety of additional mutations and nucleotide modifications are provided within the human-bovine chimeric RSV of the invention to yield desired phenotypic and structural effects.

Recombinant respiratory syncytial virus (RSV) having the position of genes shifted within the genome or antigenome of the recombinant virus are infectious and attenuated in humans and other mammals. Gene shifted RSV are constructed by insertion, deletion or rearrangement of genes or genome segments within the recombinant genome or antigenome and are useful in vaccine formulations for eliciting an anti-RSV immune response. Also provided are isolated polynucleotide molecules and vectors incorporating a recombinant RSV genome or antigenome wherein a gene or gene segment is shifted to a more promoter-proximal or promoter-distal position within the genome or antigenome compared to a wild type position of the gene in the RSV gene map. Shifting the position of genes in this manner provides for a selected increase or decrease in expression of the gene, depending on the nature and degree of the positional shift. In one embodiment, RSV glycoproteins are upregulated by shifting one or more glycoprotein-encoding genes to a more promoter-proximal position. Genes of interest for manipulation to create gene position-shifted RSV include any of the NS1, NS2, N, P, M, SH, M2(ORF1), M2(ORF2), L, F or G genes or a genome segment that may be part of a gene or extragenic. A variety of additional mutations and nucleotide modifications are provided within the gene position-shifted RSV of the invention to yield desired phenotypic and structural effects.
摘要:
Recombinant respiratory syncytial virus (RSV) are provided which express one or more immune modulatory molecules. The recombinant virus is modified by addition or substitution of a polynucleotide sequence encoding the immune modulatory molecule, which is preferably a cytokine. Introduction of the cytokine increase, decrease, or otherwise enhances aspects of viral biology and/or host immune responses to RSV to facilitate vaccine use of the virus. Cytokines for use within the invention include but are not limited to interleukin 2 (IL-2), interleukin 4 (IL-4), interleukin 5 (IL-5), interleukin 6 (IL-6), or interleukin 18 (IL-18), tumor necrosis factor (TNF) alpha, interferon gamma (IFN), and granulocyte-macrophage colony stimulating factor (GM-CSF). The polynucleotide or immune modulatory molecule is preferably added or substituted into the recombinant viral genome or antigenome, typically at an intergenic or other non-coding site, as a separate gene but may be otherwise expressed, for example as a fusion protein.
摘要:
A cursor control system for use with a data terminal having a display consists of a radiation source and associated radiation sensor. Either the source or sensor is fixed with respect to the display while the other is moveable and may be fixed to the user's head. The system translates the motion of the user's head into a directional signal for controlling cursor position on the screen.
摘要:
A drier information system is provided including display means relating to a given region of the system which means serves, at least while a drying cycle is in operation, to provide a visual display indicating at least one of the following parameters: the extent of the region; a boundary of the region; direction or example of manipulation of a pair of hands or other article while in the region to provide for a preferred drying sequence. The visual display can represent the parameters as a two dimensional array within or adjacent the region. Alternatively the visual display can represent the parameters as a virtual or actual three dimensional array within or adjacent the region.
摘要:
A Connector comprising a rigid base member covered by a resilient layer base member further comprising a contact member formed of a head portion and a stem portion, whereby the head portion is arranged to project from the outer surface of the resilient layer and the stem portion is located within the base member and the resilient layer, the stem portion being held in position by a retaining member. Preferably, the resilient layer is formed of an elsatomer material which extends around the periphery of the connector.
