Abstract: Detachable auxiliary power systems are disclosed. In some embodiments, the power system comprises a housing with a cavity, and a detachable portion configured to be received into the cavity. The detachable portion includes a power source such as a rechargeable battery, and may include additional electrical circuits to manage the charge and discharge of the battery. The housing includes a cable for electrically connecting the housing to an external electrical system, such as a vehicle electrical system. When the detachable portion is inserted into the housing, it is electrically connected to the cable, and so able to be charged from the external electrical system, and selectively provide power from the power source to the external electrical system, such as for jump-starting a vehicle.

Abstract: A hair color delivery system includes a flexible bottle, a dispensing cap having a tapered nozzle, an asymmetric bi-directional valve assembly, and a dispensing tube. The valve assembly comprises a platform, and a pair of valves, comprising tapered extensions through which fluid may be expelled from the bottle and ambient air may enter the bottle. The valves are offset from each other so that they are not co-axial or rotationally symmetric. The delivery system enables a method of substantially continuous delivery of a fluid chemical, yielding a hair treatment that it is easy and safe to use in which the tapered nozzle stays fully charged with product as air can be admitted to a dispensing bottle through a different valve than that used for dispensing.
