    • Systems and methods for preventing water from freezing in a spa or hot tub featuring a spa pack having a pump, heater and controller connected to a spa power supply through a ground fault circuit interrupter. A sensor is used to monitor an operating condition of the spa pack that is initially electrically connected to the spa power supply in order to activate at least one freeze prevention device if the operating condition of the spa pack changes due to electrical disconnection from the spa power supply by the ground fault circuit interrupter. The freeze prevention device features a heater, a circulating pump or both, and keeps water in the tub and the piping associated therewith from freezing. A switching arrangement is provided for deactivating the system outside the winter season when freeze protection is not required.
    • 用于防止在温泉或热水浴缸中的水冻结的系统和方法,其具有通过接地故障断路器连接到水疗电源的泵,加热器和控制器的温泉包。 传感器用于监测最初电连接到水疗电源的水疗包的操作状态,以便如果由于与水疗电源断开而导致的温泉包的操作条件发生变化,则激活至少一个防冻装置 由接地故障电路断路器供电。 防冻装置具有加热器,循环泵或两者,并且将水保持在浴缸中,并且与其相关联的管道不会冻结。 提供了一种切换装置,用于在不需要防冻保护的情况下使冬季以外的系统停用。

    • Multi-media project editing methods and systems are described. In one embodiment, a project editing system comprises a multi-media editing application that is configured to enable a user to combine multiple different video clips into a video project. A bitmap processor coupled with the multi-media editing application receives a first bitmap that can be used to render a transition between video clips and automatically processes the first bitmap to provide a different transition between video clips. Processing of the first bitmap can include, without limitation, using the first bitmap to provide an entirely new and different second bitmap, or processing the first bitmap in a manner which renders a transition that is different from the transition defined by the first bitmap. In one embodiment, a user is able to enter one or more parameters, through a user interface (UI), with the parameters then being used to manipulate the first bitmap to provide the different transition. Processing of the first bitmap can include many different operations, among which can be included one or more of: stretching, shrinking, replication, and offsetting. In addition, the first bitmap can be processed to include, in the transition it defines, a border that is not otherwise defined by the first bitmap.
