Abstract: Circuits, methods, and systems are directed to controlling the amount and polarity of current to multiple loads with switches, where the loads share switching components. The loads may be thermoelectric elements, which heat o r cool based on the state of the switches. The switches may be run in a sing le mode during a duty cycle, or multiple successive modes during the duty cy cle to achieve full control of the loads.

Abstract translation: 电路，方法和系统旨在通过开关来控制到多个负载的电流的数量和极性，其中负载共享开关元件。 负载可以是基于开关状态的加热或冷却的热电元件。 开关可以在占空比期间以单一模式运行，或者在占空比期间以多个连续模式运行，以实现负载的完全控制。

Abstract: In one arrangement, a cartridge includes a cartridge body defining a holding compartment, first and second fractioning compartments, and a number of flow channels formed within the cartridge body. A predetermined quantity of fluid can be held in the holding compartment when the cartridge body is held in a first orientation, and can be poured from the holding compartment to the first fractioning compartment by rotating the cartridge body about a predefined rotation axis to a second orientation, spilling the fluid from the holding compartment to the first fractioning compartment through one of the flow channels. The first fractioning compartment is such that when the cartridge body is in the second orientation, not all of the fluid can be contained in the first fractioning compartment, and fluid that overflows the first fractioning compartment flows through a second flow channel to the second fractioning compartment.
