Abstract: An acute kidney injury predicting system and a method thereof are proposed. A processor reads the data to be tested, the detection data, the machine learning algorithm and the risk probability comparison table from a main memory. The processor trains the detection data according to the machine learning algorithm to generate an acute kidney injury prediction model, and inputs the data to be tested into the acute kidney injury prediction model to generate an acute kidney injury characteristic risk probability and a data sequence table. The data sequence table lists the data to be tested in sequence according to a proportion of each of the data to be tested in the acute kidney injury characteristics. The processor selects one of the medical treatment data from the risk probability comparison table according to the acute kidney injury characteristic risk probability.

Abstract: There is provided a smoke detector including a first light source, a second light source surface, a light sensor and a processor. The light sensor receives reflected light when the first light source and the second light source emit light, and generates a first detection signal corresponding to light emission of the first light source and a second detection signal corresponding to light emission of the second light source. The processor distinguishes smoke and floating particles according to a similarity between the first detection signal and the second detection signal.

Abstract: An electrostatic discharge protection apparatus is described. A multi-hole conductive layer is placed between a multi-hole structure and an electronic element of an electronic device. The multi-hole electric conductive layer contacts a conductive layer on the inside surface of a case of the electronic device. It dissipates the electric charges accumulated on the multi-hole structure because of a lack of the conductive layer, and thus prevents the accumulated electric charges from discharging to damage the electronic element.

Abstract: An electrostatic discharge protection apparatus for a circuit board is described. The electrostatic discharge protection apparatus has a nonconductive layer and a conductive layer. The conductive layer is used to dissipate electric charges accumulated on the pointed ends of the circuit board, and thus improves the electrostatic discharge protection ability of the circuit board.

Abstract: A device for actuating a punch includes a base for supporting the punch and an arm adjustably secured on the base. A barrel is secured to the arm for slidably receiving a shaft, and a lever is pivotally secured to the barrel and coupled to the shaft for moving the shaft to actuate on the punch with an increased torque. A spring is engaged with the shaft for biasing the shaft away from the punch. A seat is secured on the base and includes a bore for slidably receiving the lower portion of the arm. A latch may adjustably secure the arm to the seat according to the size of the punch.

Abstract: A punch includes a mold piece disposed on a plate, and a barrel secured on the plate with an arm. A shaft is slidably received in the barrel and includes a punch rod secured to the bottom end. A lever has one end pivotally coupled to the barrel and has a middle portion secured to the shaft for moving the shaft and thus the punch rod downward to actuate on the mold piece. A housing includes a hub having one or more guide rails extended inward of the hub to engage with the punch rod and to guide the punch rod to move relative to the housing.

Abstract: A punch includes a socket disposed on a plate, a barrel supported above the plate, a shaft slidably received in the barrel and a mold piece detachably secured to the shaft. One or more levers have one end pivotally secured to the barrel and have a middle portion coupled to the shaft for moving the shaft and the mold piece downward to actuate on the socket. The mold piece is detachably secured to the shaft with a threaded ferrule. The punch includes one or more mold pieces and sockets of various shapes which may be replaced with each other.

Abstract: A mold-pressing device including a seat body formed with a horizontal fissure at one end and a vertical chamber communicated with the fissure. A mold block is disposed in the chamber. One face of the mold block is disposed with a solid die, while the other face of the mold block is disposed with a channel passing through the mold block. A pressing lever is pivotally disposed in the channel of the mold block. A housing covers the seat body and is formed with a window for a pressing section of the pressing lever to extend therethrough. In use, a paper or a sheet is pushed into the fissure of the seat body and then the pressing section of the pressing lever is depressed, whereby a protuberance of the pressing lever is moved downward to force the mold block downward with the die punching the paper or the sheet placed in the fissure. Therefore, a product with a shape as that of the die is formed.

Abstract: A non-sparking rotatable switch apparatus for a multi-speed fan includes stationary contacts positioned at two different levels relative to a plane of rotation of the switch. The rotatable portion of the switch apparatus includes upwardly extending contact sheets, some of which extend only to the lower level at which contacts are positioned and at least one of which extends to the higher level at which contacts are positioned. The higher level upwardly extending contact sheets have different widths than the lower level sheets, thereby changing the timing at which the upwardly extending contact sheets engage the respective contacts.
