Abstract: A self-power air refresher system includes an air refresher apparatus and a plant microbial fuel cell (PMFC). The air refresher apparatus includes a fan, a filter located on an air-outlet path of the fan, and an energy storage device connected to the fan. The PMFC is disposed on the air-outlet path and includes soil contained in a container, a plant planted in the soil, and a first and second electrodes. The interaction between roots of the plant and microorganisms near the roots generates electrons, and the electrons are transmitted to the energy storage device through the first and second electrodes installed in the soil so as to enable the energy storage device to supply power to the fan. The air that has passed through the filter enters the soil of the PMFC, and is filtered by the plant and then discharged from the container.

The sensing system comprises a plurality of sensors and a host. The sensors are used to respectively sense the movement of the sensing points to generate a plurality of corresponding multi-dimensional coordinate values.

The calculating unit derives movement traces of the sensing points under at least one of dynamic-movement modes according to a specific second static pattern dedicated to the object under detection and multi-dimensional messages corresponding to the sensing points, and further generates a specific mobile pattern corresponding to the object.

Abstract: A 3D model component comparing system and method thereof are provided. The 3D model component comparing system includes a model-capturing unit, a processing unit, and a message-prompting unit. The model-capturing unit obtains a first model and a second model in a model design interface. The processing unit compares a plurality of components of the first model and a plurality of components of the second model to obtain a plurality of components which have different names, and analyzes them to determine whether the plurality of components which have different names have identical component data correspondingly or not. The message-prompting unit outputs a renaming prompting message if the plurality of components, which have different names, have identical component data correspondingly. Thus the design error rate is reduced.

Abstract: A movement-orbit sensing system is provided for collecting movement-orbits of sensing points of an object under detection, which comprises sensors, a host a comparison unit, and a determination unit. The sensors are used for outputting sensed signals and multi-dimensional coordinate value. The host comprises units for generating a multi-dimensional coordinate signal and sensed values, and a movement-obit architecture unit is used for architecting the movement-orbit of each sensing point according to the multi-dimensional coordinate signal and sensed values. The comparison unit is used for comparing the movement-orbit of the object under detection with a standard movement-orbit information, thereby obtaining an offset value. The determination unit is used for determining whether the offset value is greater than a preset value. If the offset value is greater than the preset value, the movement-orbit of at least one of the sensing points is determined to be erroneous.

The 3D model component comparing system includes a model-capturing unit, a processing unit, and a message-prompting unit. The model-capturing unit obtains a first model and a second model in a model design interface. The processing unit determines whether a plurality of component data of a plurality of components in components, which have the same component names, between the first model and the second model are all accordingly identical. The message-prompting unit outputs a renaming prompting message if the plurality of component data of the plurality of components in the components which have the same component names between the first model and the second model are not all accordingly identical. Thus design error rate is reduced.

Abstract: A programmable CAD system suited for preventing interference between components and a chassis, and a method thereof are provided. The method comprises the following steps of: automatically obtaining a protruding length of a pin tail of a component outwardly protruded from a circuit board, by a first arithmetic unit; obtaining a distance, between a chassis and a surface of the circuit board corresponding to a location where the component is disposed, from a component information unit, obtaining an interference value according to the protruding length and the distance, by a second arithmetic unit; and determining whether the interference value is greater than zero, by a determine unit. If the interference value is greater than zero, the component is determined to be interfering with the chassis; and if not, the component is determined not to be interfering with the chassis.

The 3D model component comparing system includes a capturing unit, a setting unit, a processing unit and a prompting unit. The capturing unit acquires a first model and a second model.

The prompting unit outputs a prompting message if the coordinate values of the plurality of components, which have the same component names, between the first model and the second model are not identical. Thus design error rate is reduced.

A circuit board is obtained, wherein the circuit board has set a first height limit, and parts of the coordinate areas have set a plurality of second height limits respectively. The second height limits are lower than the first height limit. A Keep-out area is established according to the second height limits of the coordinate areas and the first height limit.

Thus, users can immediately check whether interference or clashed in space occurs between the circuit board and the substrate-boarded space.
