Abstract: The present disclosure relates to a shared transfer switching system with built in relay testing ability, for transferring power received by a load from a preferred AC power source to an alternate AC power source, or transferring power being received by the load from the alternate AC power source to the preferred AC power source. The system selectively controls various ones of the relays used to apply power from either the preferred or alternate power sources to the load, such that the relays are switched from open to closed states at controlled times, while voltage measurements are made at select locations between the relays. The system can identify which specific ones of a plurality of relays associated with each of the preferred and alternate power sources has properly opened and closed, and thus verify that all of the relays needed to switch between the preferred and alternate power sources are operating properly.

Abstract: This disclosure provides isolated antibodies, for example, monoclonal antibodies, that specifically bind to the C-C Motif Chemokine Receptor 8 (CCR8) expressed on the surface of a cell and mediate depletion of the CCR8-expressing cell by anti-body-dependent cellular cytotoxicity (ADCC). The disclosure provides methods for treating a subject afflicted with a cancer comprising administering to the subject a therapeutically effective amount of an anti-CCR8 antibody as monotherapy or in combination with an anti-cancer agent such as an immune checkpoint inhibitor, for example, an anti-PD-1 or anti-PD-L1 antibody.

Abstract: A printed circuit board may have embedded strain gauges. A strain gauge may be formed from a metal trace on a polymer substrate. The metal trace may form a variable strain gauge resistor that is incorporated into a bridge circuit for a strain gauge. The printed circuit may have a rigid printed circuit layer with a recess that receives the polymer substrate. Metal pads on the polymer substrate may be coupled to respective ends of the variable strain gauge resistor. The rigid printed circuit substrate with the recess may be laminated between additional rigid printed circuit layers. Vias may be formed through the additional rigid printed circuit layers to contact the metal pads. Embedded strain gauges may be used in gathering strain data when strain is imparted to a printed circuit during use of the printed circuit in an electronic device or during testing.

Abstract: A method of plugging a pipeline includes the steps of welding onto the exterior of the pipeline (10) first (12) and second (14) spaced apart collars, each having a sealing face (26,26A) in a plane perpendicular the pipeline (10) axis. A containment housing (34,36) is affixed by welding to the collars (12,14) to fully encompass a section of the pipeline (10) between the collars (12,14). A tapping (60) machine is then removably attached to an open top of the containment housing (34). Using the tapping machine (60) a short length of the pipeline (10) is cut and removed from between the collars (12,14) leaving two open exposed pipe ends (78,80). First and second seal elements (92,94) are positioned between the collars (12,14), Each having a forward sealing face. The seal elements (92,94) are forced apart from each other into sealing engagement with the collar sealing faces thereby closing the open, exposed ends (78,80) of the pipe (10).
