Disclosed is a food waste treatment device, and more particularly a food waste treatment device with a minimal volume and a simple structure for agitating, crushing and drying food waste without giving off offensive odors and then discharging the disposed waste with a reduced volume. Thus, the food waste treatment device may be installed even in a narrow space, easily handled, and adapted to dispo...

Reflectance based methods and devices are provided for determining the concentration of an analyte in a fluid sample. In practicing the subject methods, a fluid sample is applied to a matrix impregnated with a signal producing system. The signal producing system produces a detectable product in an amount proportional to the amount of analyte in the sample. A surface of the matrix is then illuminat...

An apparatus for measuring recrystallisation in a frozen sample includes a sample holder (5) which includes a recess (7) for receiving a sample receptacle (9). A cooling mechanism alters the temperature of the sample while it is in the sample holder. A light source (15) directs a beam of light at the sample in the sample holder via a light path (13), and a detector (17) detects the intensity of tr...

This invention is directed to a plastic composite comprising color images printed onto a polyethylene terephthalate (PET) substrate using thermal transfer (TT) printing technology. The PET layer is then bonded to a second PET layer using a thermally activated adhesive, preferably ethylene vinyl acetate copolymer (EVA). The bonded PET layers are then disposed between two layers of plasticized PVB, ...

An electrochemical assay includes a method for determining with great accuracy the time at which an applied sample bridges a gap between the electrodes of an electrochemical cell. The method involves applying a constant small current across the gap, while monitoring the potential difference between the electrodes. The time at which the sample bridges the gap is marked by a sharp drop in the potent...

The cleaner has a cleaner body (110) including a programmed control unit that executes a cleaning operation as per predefined values. A driving unit is driven according to a control signal from the control unit. A dust suction unit captures and collects dust by a vacuum motor. A cleaning unit (200) with a rotating moist fabric (210), is detachably fixed at a lower surface of the body.;

The robot cleaner has a body with a drive part and a suction member and a bumper (200) attached to the cleaner body by a support structure (240), when a collision occurs between an obstacle and the cleaner the bumper moves towards the cleaner body to absorb the shock and protect the body. In response to the movement a sensor (300) is turned on and affects the controller in order to change the dire...

The method involves calculating a characteristic value of movement of a vehicle (1) along a predefined plot of a trip according to speed of actual displacement and the plot. A function e.g. security function such as anti-accident function, of the vehicle is activated based on the value. The anti-accident function is activated under a regulation form reducing the speed of displacement. - The method...

Systems and methods for identifying foreign objects and debris (FOD) and defects during fabrication of a composite structure. The system includes at least one light source positioned to emit light that illuminates a portio n of the composite structure with bright field illumination and that also illuminates another portion of the composite structure with dark field illumination. The bright field i...
