摘要： Methods and systems for testing an integrated circuit during an assembly process are described. The integrated circuit is received from inventory. The integrated circuit is placed in a socket on a first circuit board for system-level testing. The system-level testing is performed prior to placement and permanent attachment of the integrated circuit onto a second circuit board. Provided the integrated circuit passes the system-level testing, the placement and permanent attachment of the integrated circuit to the second circuit board is the next step following the system-level testing in the assembly process.

摘要： A method and system for controlling downshifting in an automated mechanical transmission system (10) utilized on a vehicle. When an automatic power downshift from a currently engaged ratio (GR) is required, the engine acceleration (EA) is monitored and compared with an engine free acceleration (EFA) to detect a false Neutral condition and to take appropriate action accordingly. Alternatively, a false Neutral condition is detected when the Absolute Value of the rotational speed of the output shaft (OS) times the currently engaged gear ratio (GR) minus the rotational speed of the input shaft (IS) is less than a predetermined value (ABS((OS*GR)−IS)).

摘要： The present invention provides the complete genomic sequence of a novel human coronavirus, coined as human coronavirus-HKU1 (“HCoV-HKU1”), isolated in Hong Kong. The virus belongs to the order Nidovirales of the family Coronaviridae, being a single-stranded RNA virus of positive polarity. Futher study on nasopharyngeal aspirates from patients with community-acquired pnbeumonia has revealed that there are two genotypes, genotype A and genotype B, for this virus. In addition to the genomic sequences of these two genotypes, the invention provides the deduced amino acid sequences of the complete genome of the CoV-HKU1. The nucleotide sequences and deduced amino acid sequences of the HCoV-HKU1 are useful in preventing, diagnosing and/or treating the infection by HCoV-HKU1. Furthermore, the invention provides immunogenic and vaccine preparations using recombinant and chimeric forms as well as subunits of the HCoV-HKU1 based on the nucleotide sequences and deduced amino acid sequences of the HCoV-HKU1.
