Patent number: 10256621Abstract: A circuit interrupter that includes a passive integration channel structured to receive an output signal from a di/dt current sensor and generate a first signal output based on the output signal, and an active integration channel structured to receive the output signal from the di/dt current sensor and generate a second signal output based on the output signal that is proportional to the primary current received by the di/dt current sensor. Circuit protection functionality is provided based on the first signal output responsive to the primary current being determined to be greater than a threshold level, current metering and circuit protection functionality is provided based on the second signal output responsive to the primary current being determined to be less than or equal to the threshold level, and a seed current value is provided to the active integrator based on the first signal output.Type: GrantFiled: June 15, 2017Date of Patent: April 9, 2019Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Theodore James Miller, Daniel A.

Publication number: 20060093613Abstract: The present invention relates to a recombinant soluble T cell receptor. The T cell receptor (TCR) is refolded and comprises a recombinant TCR ? or ? chain extracellular domain having a first heterologous C-terminal dimerization peptide; and a recombinant TCR ? or ? chain extracellular domain having a second C-terminal dimerization peptide which is specifically heterodimerized with the first dimerization peptide to form a heterodimerization domain, which may be a coiled coil domain. The invention also provides nucleic acid sequences encoding the recombinant TCR and a method for producing the recombinant TCR. The TCR may be labelled with a detectable label so as to enable the detection of specific MHC-peptide complexes. Alternatively, it can be linked to a therapeutic agent such as a cytotoxic agent or an immunostimulating agent so as to deliver such an agent to the site of a specific MHC-peptide complex.Type: ApplicationFiled: June 27, 2005Publication date: May 4, 2006Applicant: AVIDEX LIMITEDInventors: Bent Jakobsen, John Bell, George Gao, Benjamin Willcox, Jonathan Boulter
