Abstract: An apparatus for use in a host system to control a storage device is provided. The apparatus includes a power-loss detection module, a power-loss handling command buffer and a storage host controller. The power-loss detection module is configured to determine whether a power-loss event occurs according to a level of a supply voltage. The power-loss handling command buffer is configured to store one or more power-loss protection commands. The storage host controller is coupled to the power-loss detection module and the power-loss handling command buffer and configured to execute the one or more power-loss protection commands in the power-loss handling command buffer in response to the power-loss event, thereby to perform one or more specific operations on the storage device.

Abstract: A support device for kneel-down work comprises two spaced support members each support member comprising an end plate and an extension member including an end securely connected to the end plate. A knee plate comprises an end pivotally connected to the other end of the extension member of each support member. A seat frame comprises a seat and two parallel connecting plates respectively extending from a side of the seat. Each connecting plate is pivotally connected to an associated one of the end plates.
