Abstract: Disclosed are compositions, methods, systems, and kits for the detection of markers of interest, which may allow for sequential multiplexing. In some cases, the methods comprise sequential staining of biological samples with detection sets and removal of bound detection agents which may allow for sequential staining with additional detection agents.

Abstract: A pet waste grasping device including a telescopic assembly, a claw assembly, a light assembly and a bag assembly is disclosed. The pet waste grasping device is a pet waste scooper for collecting of pet waste without the need for a user to come in direct contact with the pet waste. The pet waste grasping device include an elongated shaft having a handle and a trigger-like actuator at the proximal end of the shaft, wherein the distal end of the shaft supports an illumination device that projects light downward and a series of extendable fingers which retract and expand when the trigger-like actuator is manipulated to release a bag with pet waste therein. The extendable fingers support the bag which is preferably a plastic bag that is placed over the extendable fingers manually.

Abstract: Systems and methods are provided for delivering power from a first energy source to a second energy source. An electrical system for delivering power from a first energy source to a second energy source comprises an interface configured to be coupled to the second energy source, a switching element coupled between the first energy source and the interface, and a processing system coupled to the switching element and the interface. The processing system is configured to identify a connection event based on an electrical characteristic of the interface that is indicative of the interface being coupled to the second energy source and operate the switching element to provide a path for current from the first energy source in response to identifying the connection event.

Abstract: The present invention compact creel using the OETO method that accommodates an increased number of packages in a relatively small footprint while providing a straight in-line delivery path in which fiber bends and changes in direction are minimized. In addition, the present invention is a system, apparatus and method for tension control in a fiber feeding system that provides a fast and reliable method for feeding high tack elastomeric thread or fiber from a package to a manufacturing process. Furthermore, the present invention provides a method and apparatus for changing packages on a creel without interrupting the manufacturing process. In particular, the compact creel of the present invention provides for continuous operation of unwinding and fiber delivery by allowing a standby package to be loaded on the same mandrel as an active package that is presently being unwound.

Abstract: A system, apparatus and method for tension control in a thread feeding system that provides a fast and reliable method for feeding high tack elastomeric thread or fiber from a package to a thread processing system. A drive and tension control apparatus at least one of increments, maintains or decrements the speed of a driven take-off roll when the tension is out of a predetermined range of operation. A tension controller devices measures tension and determines whether the average tension for the moving threads is out-of-range relative to the predetermined tension values for the threads. Alarms and other indicators may also be used to determine the threads are at least one of broken, not moving and out-of-range for tension control.

Abstract: The invention provides an over-end take off device (OETO) for unwinding elastomeric fiber. The invention further provides a method for unwinding elastomeric fiber for downstream processing.

Abstract: An over-end takeoff device (OETO) and a method for unwinding elastomeric fiber from a package are provided. The OETO includes a fiber guide spaced apart from the fiber package and disposed at an acute angle between 0° and 30° to the rotational axis of the package.
