Abstract: A control device for a first lighting load on a vehicle or trailer features an input connected to a lighting circuit through which a different second lighting load is operated, thus placing the controller in parallel relation with the lighting circuit, and a power output connected to the first lighting load on the vehicle or trailer. The controller is configured to detect from the input, a signal change sequence in the lighting circuit that comprises an initial high-to-low signal downstep, and a subsequent low-to-high signal upstep completed within a limited time window triggered by the initial high-to-low signal downstep. In response to detection of this signal change sequence, the controller energizes the first lighting load. If the second lighting load is the vehicle headlights, for example, a user can turn on the first lighting load by momentarily flipping the headlight switch off, and then quickly back on again.

Abstract: A method is provided for controllably delivering an additive fluid into a host fluid in a target system at a desired volumetric flow rate. The method comprises: providing a binary supply injector connected in an additive fluid delivery system between a pressurized supply of the additive fluid and the target system. The binary supply injector is controllable between an ON state which permits flow of the additive fluid therethrough and an OFF state which prevents flow of the additive fluid therethrough. The method involves iteratively repeating: estimating a volumetric flow rate of the additive fluid between the pressurized supply and the target system; and if the estimated volumetric flow rate of the additive fluid is greater than the desired volumetric flow rate, controlling the supply injector to its OFF state; or if the estimated volumetric flow rate of the additive fluid is less than the desired volumetric flow rate, controlling the supply injector to its ON state.

Abstract: Provided herein is a composite metal pipe fitting comprising a substantially cylindrical metal body and a metal disk securely fitted in a cross-sectional position inside the body. Also provided herein is a method comprising fashioning a cylindrical metal body to comprise a first inside diameter and second inside diameter; fixing a metal disk having a hole against the first inside diameter in a cross-sectional position of the cylindrical metal body; and from the body and disk, forming a pipe fitting having an intersecting pipe receiving configuration at a proximal end and a coaxial pipe receiving configuration at a distal end of the body.

Abstract: Provided is an HPV E6, E7 mRNA assay, referenced herein as the “In Cell HPV Assay,” that is capable of sensitive and specific detection of normal cervical cells undergoing malignant transformation as well as abnormal cervical cells with pre-malignant or malignant lesions. The In Cell HPV Assay identifies HPV E6, E7 mRNA via in situ hybridization with oligonucleotides specific for HPV E6, E7 mRNA and quantitates the HPV E6, E7 mRNA via flow cytometry. The In Cell HPV Assay can be carried out in less than three hours directly from liquid-based cervical (“LBC”) cytology specimens. The In Cell HPV Assay provides an efficient and highly sensitive alternative to the Pap smear for determining abnormal cervical cytology.

Abstract: In one aspect, the present invention provides an in situ process of simultaneously detecting a specific predetermined nucleic acid sequence and a specific predetermined cellular antigen in the same cell. In accordance with that process, the antigen is labeled with a biotin- or DNP-tagged antibody that specifically immunoreacts with the antigen, the specific nucleic acid sequences in the cell are amplified, the amplified nucleic acid sequences are labeled with a fluorescently-tagged nucleic acid probe that specifically hybridizes to the amplified nucleic acid sequences, and the labeled nucleic acid sequences and labeled cellular antigen are detected.

Abstract: The field of this invention is the detection and isolation of specific amplified DNA sequences by flow cytometry. More particularly, this invention relates to the detection of these specific amplified DNA sequences in cells so as to allow quantitation of viral burden of patients infected with a virus. The method is particularly adapted to detection of HIV-1 proviral DNA sequences and the assessment of activity of the virus in a cell.

Abstract: An information processing system includes a processor responsive to instructions for performing operations. The processor includes instruction queue for fetching and storing instructions in advance of execution and the system is responsive to certain of the instructions for causing execution of a corresponding sequence of instructions. A prefetch monitor includes circuitry for detecting instructions which may result in the execution of a corresponding sequence of instructions. The prefetch monitor further includes an instruction substitution circuit which is responsive to the detecting circuitry for inhibiting the reading of following instructions from a memory to the processor and is responsive to instruction fetching operation of the processor for reading null instructions to the processor.
