Abstract: There are described a system and a method of detecting the passage of persons or objects through an entry-exit (4) of a delimited space (2). The direction of passage is detected on the basis of the reception, by a portable electronic unit (40) with which the person or the object is equipped, of first and second electromagnetic signals (a, b) respectively transmitted in respective spatially separate and partially overlapping first and second communication regions (A, B) each crossing an entry-exit zone (32) defined by the entry-exit. The first and second electromagnetic signals are transmitted substantially in phase at the same frequency and each comprises an identical message portion (100), one of said first and second electromagnetic signals further comprising an additional message portion (150) identifying the corresponding communication region (A, B), transmission of the other of said first and second electromagnetic signals being interrupted during the transmission of said additional message portion.

Abstract: A pressure-type flow rate control apparatus controls the flow rate of fluid passing through an orifice to a target flow rate. The flow rate of a compressible fluid under non-critical conditions (sub-sonic) passing through the orifice is calculated by: Qc=KP2m(P1?P2)n so that the flow rate can be controlled to the target flow rate with high precision and speed. Also provided is an improved pressure-type flow rate control apparatus in which a pressure ratio P2/P1=r, obtained from an upstream pressure P1 and a downstream pressure P2 is constantly compared with a critical value r, and under critical conditions (r?rc), the flow rate is calculated by: Qc=KP1. Under non-critical conditions (r>rc), the flow rate is calculated by Qc=KP2m(P1?P2)n.

Abstract: The invention relates to an adjustment device (1) for an internal combustion engine, particularly for adjustment of shafts with adjusting members. Heretofore known open/close switches are relatively large and cost-intensive in their production. For this reason, an adjustment device (1) is proposed, in which a set of gears (5) simply comprising a worm (7) and a partial ring worm gear (8) wherein pin magnets are disposed on the partial ring worm gear. The pin magnets (11) work functionally together with a non-moving switch (16) disposed in a housing (2,3) when a signal is produced by means of the magnetic field of the magnets (11) passing by the switch (16), which stops motor (4) and, as the case may be, predetermines a direction change. Thus, a right/left movement of the motor (4), along with a timely turning off of the motor can be achieved with only one external control signal.

Abstract: This invention relates to the controlled two-dimensional structural transition of a dipole monolayer at a metal, semi-conducting or insulating interface. The dipole monolayer consists of objects/molecules with a permanent electric dipole moment. A transition between the structures of the molecular layer can be performed locally and reversibly by applying an electrical field and the structures/patterns can be reversibly switched many times between two different structures/states. Both of the two structures, the ordered and the disordered structures, are intrinsically stable without the presence of the switching electrical field. This controlled switch of the local layer structure can be used to change layer properties (i.e., mechanical, electrical, optical properties). The controlled reversible modifications of the dipole monolayer structures are usable as bit assignments in data storage applications for example.
