Abstract: A tilting board for a human being operated includes an operation plate, a base plate rotationally connected to the operation plate, a sliding rail fixed on the base plate, and an adjustment member. The sliding rail is fixed on the base plate and defines a plurality of pairs of opposite slots. One end of the adjustment member abuts against the operation plate and the other end of the adjustment member is positioned between one of the pairs of opposite slots. The degree of incline of the tilting board can be changed by moving the adjustment member from the pair of opposite slots to another one of the pairs of opposite slots.

Abstract: A rotary platform device is for supporting and rotating an assembly. The rotary platform device includes a rotary platform and a casing. The rotary platform extends up from the casing. The casing accommodates a driving device, a coupling member, and a linkage bar. The driving device provides linear motion, which is translated by the linkage bar to rotary motion applied to the rotary platform.

Abstract: A level compensation device for compensating an angle formed between a lifting mechanism and a pressing device which is horizontally placed on a product is provided. The level compensation device includes a base to be horizontally placed on the pressing device, and a rotatable plate rotatably connected to the base. The rotatable plate is driven by an external force to rotate relative to the base until an angle formed between the rotatable plate and the base is equal to the angle formed between the lifting mechanism and the pressing device.

Abstract: A modeling system and modeling method based on a logical relation, including an operation task integrating module, a task interpreter, a graph layout correcting module, a graph wiring correcting module and a database model increment correcting module, wherein the database model increment correcting module includes a graph increment calculating unit and a model increment calculating unit. The system, through description of the logical relation and based on support of the automatic wiring technology, realizes the graph-model integrated generation of a new grid model of the power system which is based on the description of the logical relation; the grid model is completely defined and modified on “one net”, which is different from the original way that the power system model is established on countless net graphs, thereby helping the grid operation manager to accurately and rapidly establish and modify the grid model of the full system.

Abstract: An apparatus includes a computer chassis and a motherboard. The motherboard defines a mounting aperture and a securing hole. The mounting aperture includes a large hole and a small hole communicating with the large hole. The computer chassis includes a bottom plate which defines a screw hole therein. A first convex projection is formed on the bottom plate. A hollow pillar is formed on the first convex projection. The pillar defines a through hole extending through the pillar and the first convex projection. A blind rivet is mounted in the through hole. The blind rivet includes a cap located above the pillar. The cap has an area larger than the small hole. The motherboard is slidable between a first position and a second position. In the first position the motherboard is located on the first convex projection, the pillar extends in the large hole of the motherboard and the cap is positioned above the motherboard.

Abstract: An electronic device enclosure includes a bottom plate, a mounting member mounted to the bottom plate, and a resilient member attached to the mounting member. At least one bridge protrudes from the bottom plate. A gap is defined between the bridge and the bottom plate, and a protrusion is formed in the bottom plate. The mounting member includes a positioning tab capable of inserting into the gap along a first direction. At least one securing tab protrudes from a free end of the resilient member towards the bottom plate. The securing tab is capable of engaging with the protrusion of the bottom plate to prevent the position tab from removing from the gap along a second direction opposite to the first direction.

Abstract: A retaining apparatus for locking a disk drive within a bracket is disclosed. The retaining apparatus includes a latch member and a securing member. The latch member includes a securing portion and a locking portion capable of locking the disk drive in the bracket. A resisting piece is formed on the securing member to resist against the latch member to move towards the bracket to block the disk drive from moving out of the bracket.

Abstract: A data storage assembly includes a bracket, a data storage device, a driving member and a locking member. The bracket includes a sidewall. The data storage device is moveably received in the bracket along a first direction parallel to the sidewall. The driving member is moveable along the first direction and includes a driving portion. The locking member includes a resisting portion corresponding to the driving portion of the driving member. The driving portion is capable of urging the resisting portion to move the locking member along a second direction perpendicular to the first direction. The storage device is secured in the bracket in a locking position along a first direction by the locking member.
