Abstract: The present invention discloses a multiphase ceramic material with a giant dielectric constant, wherein the multiphase ceramic material has a general formula of AxBnxTi1?(n+1)xO2; wherein A is at least one selected from the group consisting of Nb, Ta, V, Mo, and Sb, B is at least one selected from the group consisting of In, Ga, Al, Co, Cr, Sc, Fe (III), and a trivalent rare-earth cation; n is a molar ratio of B to A, 1<n?5, 0<x?0.1. The multiphase ceramic material possesses outstanding properties including a giant dielectric constant, a low dielectric loss, and excellent frequency- and temperature-stability. In particular, it exhibits a high insulation resistivity of higher than 1011?·cm and a high breakdown voltage, which implies it can be applied in high-energy storage devices and supercapacitors. This invention also provides a method to synthesize the multiphase ceramic material.

Abstract: Various embodiments, methods, and systems for erasure coding with overlapped local reconstruction codes, are provided. An erasure coding scheme can be defined based on Overlapped Local Reconstruction Codes (OLRC) that achieve high storage efficiency by providing fault tolerance properties that optimize reconstruction for common cases of failures while maintaining the reconstruction costs for uncommon case of failures. In operation, a data chunk is divided into data fragments. The data fragments correspond to zones. A plurality of parity fragments is computed using the data fragments. A parity fragment is computed using a subset of the data fragments. The plurality of parity fragments are assigned to the zones comprising the data fragments, where the data fragments and the plurality of parity fragments define overlapped local construction codes having a plurality of local groups. An unavailable data fragment is recoverable from at least two local groups from the plurality of local groups.

Abstract: Approaches for securing a persistent storage medium of a computer system. A computer system is instructed to transition from a sleep state to a working state. In response, a storage medium access module obtains, from a user of the computer system, an authentication credential required to access a persistent storage medium of the computer system. Upon successful validation of the authentication credential, the storage medium access module causes the computer system to transition from the sleep state to the working state. Upon being unable to successfully validate the authentication credential, the storage medium access module causing the computer system to remain in the sleep state.

Abstract: An electronic apparatus is designed for interacting with an external device. The external device stores data like photos, document and/or data streams. The electronic apparatus includes a transmission interface, a detector and a processing circuit. The detector detects whether the external device is within a predetermined distance from the electronic apparatus, e.g. direct contact or within a distance. Besides, the external device is not wire connected with the electronic apparatus. The processing circuit automatically performs a data connection with the external device when the detector detects the external device within the predetermined distance.

Abstract: A hardness adjustable platform for supporting a conveyor belt of a treadmill includes a platform body having internal spaces, and a plurality of elastic fillers moveably and respectively disposed in the internal spaces of the platform body for providing a cushion effect. The fillers are moveable relative to the platform body by an external force and divide the platform body into first and second regions having different hardness. As a result, the runner who uses the treadmill equipped with the aforesaid platform may adjust the positions of the fillers according to his/her physical condition and running speed to change the hardness distribution of the platform so as to enhance his/her running efficiency and reduce the risk of exercise injury.

Abstract: A platform for supporting a conveyor belt of a treadmill includes a wooden plate, a reinforcement plate above the wooden plate, and a shock-absorbing plate sandwiched between the wooden plate and the reinforcement plate. The shock-absorbing plate has a surface facing the wooden plate base, and a plurality of cushions protruding from the surface and stopping against the wooden plate for providing good elastic support force and cushion effect.

Abstract: A folding treadmill positioning structure includes a base frame, a treadmill platform, a first linkage connected between the base frame and the treadmill platform at the front side and defining a retaining portion, and a positioning device set, which includes a constraint member movably arranged on the rear side of the treadmill platform, a retaining member pivotally mounted on the front side of the treadmill and a connection member connecting the constraint member and the retaining member. When the treadmill platform is moved to the received position, the retaining member is forced into engagement with the retaining portion, locking the treadmill platform in the received position.

Abstract: A foot cushion adjustment mechanism includes a base frame having a mounting portion, a cushion member having a through hole defining a first opening and a locating member disposed in the through hole, and an adjustment device having a body portion inserted through the locating member and a first end portion inserted through the first opening and pivotally coupled to the mounting portion. Biasing the adjustment device causes the cushion member to be moved linearly relative to the base member to adjust the distance between the cushion member and the base member.

Abstract: A folding treadmill includes a base frame provided with a stop member, a treadbase pivotally connected to the base frame and selectively set between a horizontal operative position and a vertical non-operative position, and a positioning structure. The positioning structure includes a stop member forced out of the treadbase by a spring member for stopping against the stop member of the base frame so as to hold the treadbase in the non-operative position, a control block operable to move a pull slider to pull the stop member of the positioning structure away from the stop member of the base frame through a link for enabling the treadbase to be turned from the non-operative position to the operative position.

Abstract: A method of forming a shallow trench isolation structure is provided. A substrate having a pad oxide layer and a first insulating layer formed thereon is provided. A first trench with a small size and a second trench with a large size are formed in the substrate. A first dielectric layer and a second insulating layer are formed on the substrate sequentially. The second insulating layer is defined to form a dummy pattern to occupy a part of the second trench. A second dielectric layer is formed on the first dielectric layer and to fill into the remaining space of the second trench. A CMP process is performed to complete the shallow trench isolation trench structure.

Abstract: A method of manufacturing a cylindrical shaped capacitor includes the steps of providing a substrate that already has a polysilicon plug and a word line formed thereon, and then forming an insulation layer and a first dielectric layer over the substrate. Thereafter, the first dielectric layer is patterned to form an opening. Then, a first conductive layer and a second dielectric layer are deposited in sequence over the first dielectric layer and the opening. Next, the first conductive layer and the second dielectric layer are etched back to form spacers on the sidewalls of the opening. Subsequently, etching is carried out down through the opening using the sidewall spacers as a mask until the polysilicon plug is exposed. After that, a second conductive layer is formed over entire substrate, and then the second conductive layer is etched back so that only a portion of the second conductive layer and the first conductive layer remain.
