Abstract: A heat dissipation module and a dynamic random access memory device are provided. The heat dissipation module includes a main body, a fan, and an electrical connection component. The main body is fixedly disposed on a substrate of a memory component that includes a dynamic random access memory. The main body includes a receiving through-hole, a plurality of guide through-holes, and a plurality of exhaust through-holes. The fan is fixedly disposed on the main body and configured to allow air outside the substrate to enter the substrate through the receiving through-hole and the guide through-holes, and the air entering the substrate through the receiving through-hole and the guide through-holes is discharged outwardly through the exhaust through-holes. The electrical connection component is configured for an external power supply module to supply power to the fan.

Abstract: Disclosed is an indexing device. A first sensing unit, a second sensing unit, and a control unit are primarily disposed in the indexing device. The control unit couples to the first sensing unit and the second sensing unit. The control unit receives a first move detection signal outputted by the first sensing unit, and receives a second move detection signal from the second sensing unit. The variance of the first move detection signal and/or the second move detection signal is referred to compute a cursor control signal. Further, the first sensing unit or the second sensing unit is slidably disposed in the device's casing. This movable sensing unit allows the cursor control correlated to the moving indexing device more accurate, more stable and/or faster responsive to the user's operation.

Abstract: A mouse with multiple operation modes comprises a plurality of sensing modules with the same or different characteristics, for generating at least a movement record according to a movement status of the mouse on a reference surface; a switching module, for providing a user to select an operation mode; and a controlling module, connected to the switching module, determining the movement record provided by at least one of the plurality of sensing modules to be the source of the cursor controlling signal according to the operation mode selected by the user. When the mouse has a plurality of sensing modules with different characteristics, the mouse can be more accurate, more stable, or faster for fitting in with different requirements such as high speed, accurately, or stability. Accordingly, it is more convenient for the user to use the mouse.

Abstract: A power supply device enabling an interactive display control that can transfer the electricity data, the rotation speed data and the temperature data generated by the power supply to an interactive display module is disclosed. In addition, the interactive display module may implement prompt adjustment to output voltage and fan rotation speed in the power supply by minimal human operations.
