Cuboid-shaped secondary packaging for pharmaceutical blisters- or tubes, has inspection window which allows pharmaceutical products to be visually inspected during dispensing
Device for operating e.g. LED, of car, has controller including indicator with indicator value, where characteristic data of controller is conveyed to control unit, during initialization of control unit depends on indicator value
Hot gas engine for use in passenger car, has pistons, where volumetric processing is determined by longitudinal dimensions of stages and/or spaces and volumetric processing of stages is determined by area ratios of pistons
Electricity generation device for use in wave power plant, has retention system operated by movement of floating elements attached with generators, where movement of floating elements is transferred through connecting rod and rockers
Pump i.e. bicycle hand pump, for pumping air with high pressure/small volume and low pressure/large volume, has piston pushing air into pipe from valve terminal and pumping air at high pressure/small volume
Electric motor operated kitchen machine for cooking, refining and steaming food, has bolt elements engaged in rear grip formed at cover plate or stirring jar, where movement of bolt elements is effected by actuator arranged outside of jar
Electrical installation device e.g. switch, for e.g. actuators, installed in building, has active surface comprising arrangement deviating from rectangular characteristics with respect to main surface of carrier
Safety element for increasing falsification protection of e.g. banknotes, has thermoacoustic vibration generator, which is attached on safety document and outputs vibration energy during coupling electrical power
Writing and working area, particularly mini-office for residential areas, has shape of cube in folded position, where upper plate comprises six equal quadratic surfaces
Method for manufacturing printing stencil with substrate side and squeegee side from stencil body using ablation laser, involves introducing recess into stencil body of substrate side, and representing print pattern by through hole
Manipulator, particularly robotic palletizer, hinged bracket robot or linear actuator for machine tool, has moving manipulator element, and drive disposed on moving element of manipulator
Spoke-shaped rotary drive for use as motor for producing rotational torque around drive shaft, has driving weights rotated around axis so as to produce excess rotational torque around axle, where axle and axis intersect in space
Press composite for use as component of pump utilized to supply e.g. lubrication oil to combustion engine of motor car, has mixtures arranged in respective surfaces of joining parts, and containing hard material particle in carrier mass
Method for finding object by automatically movable device such as suction device or scavenging device, involves transporting or arranging object independent of device
Method for optimization of light dark dynamics of optical device e.g. video/film photo camera, involves controlling different lightness of single image or several image sequences by different extinction of optical device
