The fan is adapted to generate airflow. The airflow is divided into a first airflow and a second airflow entering the first flow path and the second flow path, respectively. Thereby, the cooling device is capable of matching the heat dissipation requirements of the light sources and reducing the noise generated by the cooling device by using only one fan.

Abstract: A memory access method for parallel computing, which is applied in the case that n (n?2) parallel threads invoke the same original execution module, comprises the following steps: S1) determining the number k of mirror execution modules needed to be created based on the number n of threads, wherein n?1?k?1; S2) determining the mapping policy F between the n threads and the execution modules including the original execution module and the k mirror execution modules; S3) creating k mirror execution modules, and allocating the individual private memory pool; S4) executing the n parallel threads, and making each thread invoke the execution module according to the mapping policy F, wherein each execution module only accesses its private memory pool; S5) deleting the created mirror execution modules after finishing the thread operation, and releasing the resources.

Abstract: An operating condition adjusting system includes a shipping container, plural computer cabinets, an airflow-guiding device, a controlling unit and a first sensor. The shipping container includes a first gate and a second gate. The plural computer cabinets are accommodated within the shipping container. A first airflow is introduced into the computer cabinets to remove a portion of heat of the computer cabinets, and a second airflow is exhausted from the computer cabinets. The airflow-guiding device is used for guiding the first airflow to flow toward the computer cabinets. The controlling unit is used for controlling the first gate and the second gate. The first sensor is electrically connected with the controlling unit for detecting a first temperature of an external environment. By comparing the first temperature with a second temperature, the first gate and the second gate are opened or closed under control of the controlling unit.

Abstract: A wireless input device, such as a pointing device, includes an opening on its body, and a power-supply module. The module has a carrier at one side that can accommodate at least one battery, and is arranged such that the power-supply module can be directly inserted into the opening to power the pointing device. When the insertion is completed, a cover at the other side of the module can constitute a smooth outline of the body. By the structure mentioned above, a user can replace the battery easily.

Abstract: A noble metal catalyst supported on boron nitride (BN) is used for the deep oxidation of organic compounds. The superior activity of the catalyst provides an extreme low light-off temperature and a short induction period at the deep oxidation reaction of organic compounds in air stream. The catalyst outperforms the traditional oxide-supported Pt catalysts with respect to the life and activity. The specific surface area of BN ranges from 1 to 100 m2/g, and the loading of the noble metal is in the range of 0.1 to 5.0 wt %. The noble metal can be selected from a group consisting of platinum (Pt), palladium (Pd), rhodium (Rh), Ruthenium (Ru) and a mixture thereof.
