Diabetes prediction using glucose measurements and machine learning

Diabetes prediction using glucose measurements and machine learning is described. In one or more implementations, the observation analysis platform includes a machine learning model trained using historical glucose measurements and historical outcome data of a user population to predict a diabetes classification for an individual user. The historical glucose measurements of the user population may be provided by glucose monitoring devices worn by users of the user population, while the historical outcome data includes one or more diagnostic measurements obtained from sources independent of the glucose monitoring devices. Once trained, the machine learning model predicts a diabetes classification for a user based on glucose measurements collected by a wearable glucose monitoring device during an observation period spanning multiple days. The predicted diabetes classification may then be output, such as by generating one or more notifications or user interfaces based on the classification.

During printing operation, the drive in each case of one plate cylinder/transfer cylinder pair can be disconnected from the main drive supplied via the back pressure cylinder and can be connected to an auxiliary drive. The invention is characterised in that the printing unit cylinders (11, 12, 13, 15, 16) are in an essentially vertically extending installation position, and both the printing unit cylinders (12, 13) of an upper printing unit (14) and the printing unit cylinders (15, 16) of a lower printing unit (17) can be disengaged together in each case from the back pressure cylinder (11). <IMAGE>

Sensor controlled system, vehicle and method

The invention relates to a sensor controlled system for a vehicle and a method, in particular to a sensor controlled system and method for assisting ramp approach. It is the object of the invention to eliminate the disadvantages of the current load ramp approach systems and to provide a system, a vehicle and a method that facilitates loading ramp approaches and loading/unloading procedures. Disclosed is a sensor controlled system, comprising: a ramp docking sensor mountable to a vehicle's rear end and configured to fulfill the functions required for assisting docking of a vehicle to a loading ramp, wherein the ramp docking sensor is further configured to determine a vertical distance of the ramp docking sensor relative to a ground level and to determine a vertical distance between the ground level and a loading ramp sill of the loading ramp. In this system, the ramp docking sensor can also be utilized for height-detection of a cargo hold floor with respect to a ground level without requiring specified sensors for height adjustments.

Formation of lining layers in the cathode shells of aluminium electrolytic reduction cells

The invention relates to non-ferrous metallurgy and the electrolytic production of aluminium, and can be used for lining the cathode assembly of an electrolytic cell. The present method consists in laying materials while simultaneously distributing same over the surface of a base and levelling them at a height measured from the plane of the top edge of the shell of the cathode assembly of the electrolytic cell by gradually moving a device for installing unformed lining materials along the longitudinal axis of the cathode of the aluminium electrolytic cell. Said device is configured in the form of a bridge equipped with a mechanical drive for movement. The bridge has guides on which a frame is mounted for vertical movement, said frame having cassettes provided with gates with a mechanical drive. The technical result is reduced labour costs, healthier working conditions for operatives, and better quality installation of the base of an electrolytic cell.

Ice-cube maker and drink chiller using Peltier effect - uses semiconductor string with DC passing through to cool plate on which rests an ice-cube tray and bottles of drink

The ice-cube maker and drink chiller uses the Peltier effect to give refrigeration with no moving parts, silent operation and precise temp. control. A rectifier circuit provides the direct current which is passed through a series of semiconductor junctions to produce heating at one end and cooling at the other. A small fan extracts the heat from the hot end. The semiconductors are mounted so the cold end is fixed to an upward facing plate, while the hot end is fixed to a large finned heatsink. Provision is made for an ice-cube tray (7) to rest on the plate and also for bottles (4) and glasses (5) to be inserted in suitable holes in the insulating outer case (2). The air from the hot end of the semiconductors is drawn away by a motor driven fan and exits from the case through the ventilation slots (14) provided.
