Abstract: A normally closed disc clamp system includes a housing with a rotating disc, a brake ring and a pressure-enhancing ring arranged therein. When only a first chamber is supplied with fluid, the fluid pushes the brake ring to release the rotating disc. When only a second chamber is fed with fluid, the fluid pushes the brake ring to keep the rotating disc in the braking state, and pushes the pressure-enhancing ring to compress an elastic unit. The energy generated by the compression of the elastic unit acts on the brake ring through the fluid, so that the brake ring achieves a double pressurization effect. If the action of the fluid fails, the brake ring can still provide a braking effect to the rotating disc through the elastic unit to improve operational safety. Further, the present invention further provides a rotating table using the normally closed disc clamp system.

Abstract: A method of inspecting power units applied to a plurality of power units is connected to a signal bus. The method is to disconnect the power unit having an output current from the signal bus, give a control command by a controller for raising the output current, measure the output current after the control command is given, and compare the measured output current with the target current value corresponding to the control command for determining an inspection result. The present disclosed example can effectively reduce inspection time and improve inspection accuracy.

The biodegradable metal alloy includes a magnesium-zinc-zirconium (Mg—Zn—Zr) alloy and a magnesium fluoride (MgF2) coating over the Mg—Zn—Zr alloy. The Mg—Zn—Zr alloy is a magnesium alloy containing 2.5-6.0 wt % zinc (Zn) and 0.42-0.80 wt % zirconium (Zr). Thereby the present biodegradable metal alloy not only provides sufficient fixation strength for anchoring detached tissue to hard tissue effectively but also promotes the bone growth and avoids metal/alloy artifacts in images.

Abstract: A power redundant system includes a switch module, a power-supplying module and a control unit. The switch module includes switch units. Each switch unit switches a power as an input power. The power-supplying module includes power-supplying units. Each power-supplying unit is connected to a switch unit correspondingly and converts the input power into an output power and supplies the output power to a load. The control unit controls the switch units to switch one of input sources of the power as the input power. If one of the switch units or power-supplying units is not operational, an electric power supplied by the power-supplying units connected to the remaining switch units correspondingly is greater than or equal to an electric power required by the load. When one of the input sources is abnormal, the control unit controls the switch units to switch to another input source.

Abstract: An apparatus includes a memory unit configured to store nonzero entries of a first array and nonzero entries of a second array based on a sparse matrix format; and an index module configured to select the common nonzero entries of the neurons and the corresponding weights. Since the values of the nonzero entries of the neurons and corresponding weights are selected and accessed, the data load and movement from the memory unit can be reduced to save power consumption. In addition, for a sparse neuronal network model with a large scale, through the operations of the index module, the computation regarding a great amount of zero entries can be scattered to improve overall computation speed of a neural network.

Abstract: A microelectromechanical probe has tail, head and body portions, and includes a pinpoint layer having a planarized top surface where a structural layer having first and second sides, a cutting face and a front terminal surface adjoining the first and second sides is disposed. The cutting face descends from the top surface of the structural layer toward the pinpoint layer to the front terminal surface. The front terminal surface extends from a front end of the cutting face to the top surface of the pinpoint layer. The pinpoint layer has a pinpoint protruding over the front terminal surface and located at the head portion. Within the head portion, the pinpoint layer is greater in hardness and less in electrical conductivity than the structural layer. The probe makes small probing marks, is highly recognizable in an automatic pinpoint recognition process, and can be conveniently installed.
