Abstract: The invention relates to an internal combustion engine, comprising an intake path, a crankcase, an exhaust gas path and a crankcase ventilation means, wherein the crankcase ventilation means is open, closed or separate. The internal combustion engine according to the invention comprises an intake path, a crankcase, an exhaust gas path and an open crankcase ventilation means, wherein the open crankcase ventilation means comprises a first line and a second line, wherein the first line is designed to connect the exhaust gas path to the crankcase in order to guide exhaust gas out of the exhaust gas path to the crankcase, and wherein the second line is designed to connect the crankcase to the exhaust gas path in order to discharge exhaust gas and leakage gases located in the crankcase from the crankcase and to feed them to the exhaust gas path.

Abstract: A computerized system for managing a parking lot includes: a beacon in one-way, or location sensor in two-way, communication with a smart device for locating the smart device without it having to determine its own location, a vehicle sensor for sensing the presence of a vehicle, and a computer-implemented server operable to determine from the beacon's identification or receive from the location sensor the location of the smart device. The server authorizes entry or exit of the vehicle when a smart device status indicates acceptance, and the smart device and the vehicle are both at a same appropriate location. The server updates the smart device status after a payment transaction. Entry or exit may be authorized by opening a barrier, displaying an authorization message, communicating a message to the smart device, and/or not issuing a non-authorization alert. The server may receive reservations, and may communicate lot occupancy to third-party systems.

Abstract: A radiation detector (100) adapted for detecting leakage currents is disclosed and comprises a direct conversion material (101) for converting incident radiation, at least one first electrode (108) and a plurality of second electrodes (103) connected to surfaces of the direct conversion material (101) for collecting each generated charges upon application of an electric field, at least one current measurement device (201), and a plurality of signal processing chains (210, 220, 230). Each signal processing chain comprises a readout unit (215, 216, 217, 218, 219) for discriminating between energy values with respect to the incident radiation, and a switching element (214) for sending signals on a first signal path (2141) electrically connecting one of the plurality of second electrodes with the readout unit, or on a second signal path electrically connecting the one of the plurality of second electrodes with an input to one of the at least one current measurement devices.
