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: A cleaning grinding head structure includes a main body, a connecting member connected with the main body, a stop ring mounted between the main body and the connecting member, and an operation member mounted on the connecting member. The main body has a first end provided with a fitting section and a second end provided with a connecting section. The main body has a mounting section arranged on the connecting section. The mounting section is provided with a plurality of slots. The connecting member has a first end provided with a locking section and a second end provided with a driving section. The locking section is provided with a mounting recess mounted on the connecting section. The mounting recess has a periphery provided with a plurality of ribs inserted into the slots of the main body.

Abstract: A hammering set has a rotating portion including a sidewall, two end walls connected to the sidewall, and at least one pivot portion in an accommodating space of the rotating portion. Two corresponding holes are disposed on the sidewall and communicating with the accommodating space. A shaft hole is disposed on one the end wall, a connecting portion is disposed on the other end wall for a rotating shaft. A hammering block has a through hole and a pivoting part on the pivoting portion and only swingable about the pivoting portion. A transmission shaft penetrates the shaft hole and the through hole, is rotatably disposed in the rotating portion, and is intermittently actuatable by each hammering block. A sealing assembly is provided on the rotating portion, at least seals the holes and is sealed between an inner wall of the shaft hole and the transmission shaft.

Abstract: A pneumatic sanding machine includes a body, a pneumatic motor assembly mounted in the body and a control valve detachably mounted in the body to change the path of compressed air that actuates the sanding machine. The control valve includes a first portion selectively closing one of different air passages in the body at a time, a second portion and a neck portion interconnecting the first portion with the second portion. Thus, a dust bag or a vacuum cleaner can be connected to the sanding machine to collect dust or sanding debris so that the sanding machine provides three different ways of dust collection, one of which is not to deal with the powder, the second is to collect the powder into a dust bag, and the third is to vacuum the powder into a vacuum cleaner.

Abstract: A mechanism for installing a video capture device comprises a video capture device, a wireless audio-video transmission, a case, and a lens protective cover. The case contains the video capture device. The lens protective cover has hooking pieces for being lodged in a lens hole on the case. The case is installed within a stuffed puppet behind an eye hole; and the lens protective cover is brought to outer side of the eye hole to have its hook pieces pass through the eye hole and get lodged thereon. This achieves a simple and stable attachment of a video capture device to a stuffed puppet.

Abstract: A electromagnetic wave preventing cover of an mobile phone handset is covered to a casing of a handset and is connected to the antenna seat hole of the handset, so that the transmitting antenna of the mobile phone handset for emitting electromagnetic radiation is far away from the brain, and thus, the harm of the electromagnetic wave to the brain is reduced. A cover has a space for enclosing the mobile phone handset, and has a slot at the front surface of the cover for extending the communicating covering plate of the handset, and the cover has an opening for receiving the handset into the cover. A terminal serves to insert into the antenna seat hole of the mobile phone handset. An antenna is adhered to the outer surface of the communicating covering plate of the handset. A micro-wave shield coaxial cable is fixed within the cover and has an end connected to the terminal and another end connected to the planar antenna.
