Abstract: A circuit board device includes a fixing member and a circuit board having a first hole. The fixing member includes abase having a second positioning portion and an opening, a first fixing component and a pillar structure having a first pillar body and a positioning pillar extending downward from the first pillar body and having a first positioning portion and a clamping portion. The clamping portion clamps the circuit board with the first pillar body when the first positioning portion is engaged with the first hole. The base is disposed in the first hole and abuts against the positioning pillar when the second positioning portion hooks the first hole and the opening is engaged with the positioning pillar. The first fixing component is detachably inserted into the pillar structure for clamping a first interface card with the first pillar body.

Abstract: A host casing of an electronic device includes a housing, a filler panel, and a disassembly and assembly structure. A front side of the housing has an opening. The dummy cover is disposed in the opening of the housing. The disassembly and assembly structure is disposed inside the housing. In a first state, the disassembly and assembly structure buckles with the dummy cover, thereby fixing the dummy cover. In a second state, the disassembly and assembly structure releases the dummy cover, and simultaneously pushes the dummy cover out of the opening. Therefore, the replacement action between the dummy cover and a pluggable device can be effectively simplified, so that maintenance personnel can easily assemble or disassemble the dummy cover without the assistance of additional tools.

Abstract: A server apparatus includes a casing having an opening and a fixing structure away from the opening, a tray mechanism and a server module. The tray mechanism includes a tray, a transmission member slidably disposed on the tray and having a slot, a link having an engaging structure and being slidably disposed through the slot, and a handle movably connected to the transmission member and pivoted to the tray. The server module is disposed on the tray. When the tray is disposed in the casing and the handle pivots to a mounting position, the transmission member slides relative to the tray to drive the link to pivot, so as to rotate the engaging structure to be engaged with the fixing structure.

Abstract: A method and device of achieving motion cycle time reduction that takes motor capabilities, load inertia and gravity into account and, at the same time, produces acceptable tool tip vibration upon stopping. This cycle time reduction is especially applicable to short motions of a robot where the entire motion consists of acceleration and deceleration and there is no constant velocity region. The method and device provide open loop limiting factors for axis jerk, acceleration and velocity, taking into account robot position, payload and inertia.
