The time-counting unit is used for generating a time-counting signal. The sensing unit is used for sensing the environmental status and generating a sensing signal. The displaying unit is used for displaying an image data. The processing unit controls the sensing unit and the displaying unit. The processing unit further uses a power control unit to control the power supply according to the time-counting signal and the sensing signal so that the digital photo frame operates in a normal mode. After the processing unit does not receive the sensing signal within a pre-determined period counted by the time-counting signal, the processing unit controls the power supply so that the digital photo frame operates in a power saving mode. Hereby, the goal of power saving is achieved.

摘要： The present invention provides an improved design of the signal switch, wherein the signal switch comprises at least one combinational logic such as a chip, a plurality of hosts and at least one set of input control device such as a keyboard and a mouse. The chip can further comprise one or more virtual keyboard controller and a plurality of hubs and a multiplexer. The multiplexer of the present invention is utilized to detect and interpret signals. The present invention utilizes the combinational logic design of the chips and the multiplexer to provide a signal switch that can share multi-upstream devices but less downstream ports, only one set of keyboard and mouse is required. Multiplexing downstream devices among multiple hubs, which are dedicated to upstream hosts, help reducing the whole enumeration process of time. The signal switch of the present invention provides an improved design by replacing the central processing units (CPU) of a conventional design of signal switch with the combinational logics such as chips in order to increase the speed of the enumeration, as a result, the enumerating time is thus reduced.

摘要： The present invention discloses a computer peripheral apparatus. The computer peripheral apparatus includes an USB hub, at least one build-in card reader, and a controller. Each build-in card reader is electrically connected to one built-in downstream port of the USB hub. The controller connects to the USB hub and the build-in card reader to monitor the connection requirement of the build-in card reader. When the controller determines the build-in card reader does not need to be kept connected, the controller sets the status of its corresponding built-in downstream port as a “first status,” which defines the corresponding built-in downstream port is not connected. Thus, the computer system is informed that the built-in downstream port is not connected. Therefore, if there are no USB devices connecting to other downstream ports of the USB hub, the entire computer peripheral apparatus can enter into hibernation mode, thereby lowering the power consumption
