Abstract: A storage device includes two flash memories of different flash memory types, and respectively including multiple data blocks. Each data block corresponds to a physical and a logical block address. The storage device further includes a processing module including a controller, which is capable of accessing two mapping tables respectively corresponding to the two flash memories and respectively recording the physical block addresses and the logical block addresses that correspond to the data blocks of the two flash memories. The controller is configured to determine, upon receipt of a command that contains a target logical block address therein, a selected one of the flash memories according to the target logical block address, and to locate a selected one of the physical block addresses by searching one of the mapping tables that corresponds to the selected one of the flash memories with reference to the target logical block address.

Abstract: A multi-interface storage device used in a computer under power off status is disclosed and adapted for transmitting data and communicating with an external electronic device remotely. The multi-interface storage device used in the computer under power off status comprises a transmission interface, an internet interface, a storage unit for storing data and a processing unit. The transmission interface is connected with an electronic device inside the computer, and the internet interface is connected with the external electronic device. The processing unit is connected with the storage unit, the internet interface and the transmission interface for communicating with the external electronic device through the internet interface to enable the external electronic device to store and process the data stored in the storage unit under the power off status of the computer.

Abstract: A method for recording a speaker's voice and operations during a computer aided presentation is disclosed. The method records the speaker's voice to convert into a voice data packet (VDP) when a presentation file, such as a PowerPoint file, is being executed. Once the speaker's operation to the presentation file appears (e.g. skip) in the meantime, the VDP is finished and an operational data is recorded to convert into an operation data packet (ODP), which is arranged after the VDP, while the recording of voice continues and convert into another VDP after the ODP. The VDPs and ODPs are interlacedly and sequentially combined into a presentation record file, which can be synchronously executed with the presentation file for reproducing slides, voice and operations occurring in the then live presentation.

Abstract: A storage device equipped with NAND flash memory and method for storing information thereof includes a SLC processing structure to provide fast information access and improve processing performance and a MLC processing structure to increase data density of each storage unit and reduce the cost and size of each unit of information. The data storing method includes storing important information such as operating system programs, application programs and information that have been accessed frequently in the SLC processing structure, and storing ordinary information in the MLC processing structure to reduce the cost and size of each unit of information.

Abstract: A method, medium, and system reducing the computational complexity of a Simultaneous Localization And Mapping (SLAM) algorithm that can be applied to mobile robots. A system estimating the pose of a mobile robot with the aid of a particle filter using a plurality of particles includes a sensor which detects a variation in the pose of a mobile robot, a particle filter unit which determines the poses and weights of current particles by applying the detected pose variation to previous particles, and an evolution unit which updates the poses and weights of the current particles by applying an evolution algorithm to the poses and weights of the current particles.

Abstract: A damping structure for a rotor assembly includes holes defined in a rotor and in a side board respectively and damping elements inserted into the holes of the rotor to be located between the rotor and the side board. Each damping element is received in a corresponding to one of the holes of the rotor and the side board so as to absorb vibration from the rotor to the axle of the rotor assembly.

Abstract: A damping structure for a rotor assembly includes holes adapted to be defined in an outer periphery of the inner rotor and in an inner periphery of the outer rotor respectively and damping elements inserted into the gap between the inner rotor and the outer rotor. Each damping element is received in a corresponding to one of the holes of the inner rotor and the outer rotor so as to absorb vibration from the outer rotor.

Abstract: A collapsible table is provided. The collapsible table includes a feet unit having two horizontal rods, a plurality of feet each having an upper end pivotally connected to one end of the horizontal rod. Each foot is provided with a position limit ring and a slidable sleeve disposes thereabout. A guide rod is provided pivotally between a horizontal rod and each slidable sleeve. Each position limit ring has a projecting member, and each slidable sleeve has an engage member for engage the projecting member. The position limit rings stop the slidable sleeve upon spreading the feet unit. The slidable sleeve moves the guide rods to force the feet swing down or up during spreading or collapsing. The engagement of the engage members and the projecting members securely retains the feet unit in the spread position.

Abstract: A collapsible table includes mainly a feet unit consisting of two horizontal rods, a plurality of feet respectively having an upper end pivotally connected to one of two end of each horizontal rod Each foot has a position limit ring and a slidable sleeve fixed around each foot movably under the position limit ring. A guide rod is provided pivotally between the horizontal rod and each slidable sleeve. Each position limit ring has a projecting member, and each slidable sleeve has an engage member to engage the projecting member. The position limit rings stop the slidable sleeve in spreading the feet unit, and the slidable sleeve moves the guide rod to force the feet swing down or up in case of spreading or collapsing. Engagement of the projecting members and the engage members stabilizes the feet unit in the spread position.
