Abstract: A hair treatment material applicator comprises a lid, a base, a hinge connecting the lid and base to allow pivotal movement of the lid and base with respect to each other from an open position to a closed position; and a bail pivotally mounted to the lid for pivotal movement from a use position above the lid to a latch position below the base holding the lid and base in the closed position. A compressible material, such as dense foam, is positioned in one of the lid and base; and a hair treatment material (such as highlighter, dye, bleach, protein treatment, etc.) is positioned in the other of the lid and base. The foam and material are positioned to allow strands of human hair to pass between them for uniform application of material to the strands. The hinge is an over-molded rubber hinge biasing the lid and base open.

Abstract: An enhanced interrupt controller is provided which is able to receive both hardware-generated and software-generated request signals. Data associated with each received interrupt or request signal is stored in a storage unit within the enhanced interrupt controller in an order which depends on the priority level of the data and, for data of the same level of priority, on the chronological order of receipt. The enhanced interrupt controller instructs the processor, with which it is in communication, to read the stored data from the controller in the stored order ensuring that data of higher priority is read before data of lower priority. A method of routing hardware-generated and software-generated signals from an enhanced interrupt controller to a processor is also disclosed.
