Patent number: 8042407Abstract: Tension monitoring is described using a sensor which may exhibit an offset for which compensation may be provided to produce a zero voltage amplified output or to increase dynamic range. An arrangement determines whether a power reset is responsive to a battery bounce such that an initially-measured system start-up parameter can be retained. The start-up parameter is automatically saved at start-up if the power reset is responsive to a start-up from a shut-down condition. The start-up parameter may be a zero tension amplified output responsive to the sensor offset at zero tension. Protection of a tension data set is provided such that no opportunity for altering the data set is presented prior to transfer of the data set. A housing configuration forms part of an electrical power circuit for providing electrical power to an electronics package from a battery.Type: GrantFiled: July 13, 2010Date of Patent: October 25, 2011Assignee: Merlin Technology, Inc.Inventors: Albert W.

Patent number: 7968292Abstract: Compositions and methods for the rapid and sensitive detection of a carbapenemase in a sample is provided. The compositions include novel primer and probe compositions for use in detecting the presence of this enzyme in a sample, particularly using PCR methods. These primers and probe sets can be used in amplification methods (such as PCR, particularly quantitative PCR) and packaged into kits for use in amplification methods for the purpose of detecting carbapenemase in a test sample, particularly a patient sample, particularly a direct sample. Thus, in one embodiment, the present invention provides for novel oligonucleotide primers set forth in SEQ ID NOs:1, 2, 4, 5, 7, 8, 14, 15, 17, 18, and 20, and the novel oligonucleotide probe sequences set forth in SEQ ID NOs:3, 6, 9, 16, and 19. These sequences can be used in a method of detecting carbapenemase in a sample.Type: GrantFiled: April 7, 2008Date of Patent: June 28, 2011Assignee: Becton, Dickinson and CompanyInventors: Craig C.
