Abstract: A power supply circuit (106) for a switching voltage regulator (108) connectable to a load (110) is described. In order to manage a power consumption of the switching voltage regulator (108) and in particular to minimize a power consumption of the switching voltage regulator when being operative, the power supply circuit (106) is configured for selectively supplying the switching voltage regulator (108) with one of a first input voltage and a second input voltage in response to a control signal indicative of an operative state of the load (110) such that the switching voltage regulator (108) is switched between a working state in response to the first input voltage and a standby state in response to the second input voltage.

Abstract: A method of securely routing data traffic between communication networks. In an integrated security device, a host router supports a virtual router that peers with VRF (virtual routing and forwarding) instances associated with participating networks on the host router. Each VRF instance preferably runs its own dynamic routing protocol and determines when received data traffic may be directly forwarded from one network to another and when it must be forwarded to an OE (offload engine) for enforcement of security policies or NAT (network address translation) processing.

Abstract: The invention relates to a method for automatic lamp adjustment in a microscope without beam homogenizers in the illuminating beam path and a microscope equipped for the application of the method. According to the invention, the light power in the illuminating beam path is integrally measured with a detector behind the pupil plane of the microscope objective or behind the pupil plane of the illuminating beam path and the lamp is so adjusted relative to the illuminating beam path that the light power, which is detected by the detector, is a maximum. In a microscope, which is suitable for an automated lamp adjustment, for example, after an exchange of the lamp according to the method of the invention, motorized drives are provided for adjusting the lamp. These drives are driven sequentially by an evaluation and control computer until a maximum light power is detected with a detector.

Abstract: A power supply particularly suitable for high-speed optical data transmission employs readily available components to achieve desired voltage tolerances. More specifically, a voltage signal supplied to a load is converted into a digital signal and provided to a processor that derives a digital correction signal from the digital signal. The digital correction signal is then converted to an analog correction signal and is used by a feedback control circuit in the power supply to regulate the output voltage.

Abstract: A confocal microscope has a motorized scanning table for moving the sample perpendicularly to the optical axis of the microscope. The object is illuminated simultaneously at many places by means of a light source array. The light reflected or scattered at the object is detected by means of a diaphragm array, which is conjugate to the object and to the light source array. A sensor array is provided as a detector and makes a displacement of charges possible between individual positions in the scanning direction. The sensor is a so-called TDI sensor. The displacement of the charges is synchronized with the motion of the object corresponding to the motion of the image points in the plane of the sensor array. The image data can thereby be recorded during the motion of the object, so that even large object fields can be sensed in a short time with high lateral resolution.

Abstract: The automatically acting injecting projectile, which may be fired from a rifle or handgun for anesthesia or drug treatment of animals, consists of a casing (9) on one end of which there is a plastic extension (10) and on the other a hollow needle (5). Gas propellant may be filled into pressure chamber (15) of the casing through a check valve (1) and channel (12). Upon impact of the injecting projectile in the body of the animal deformable projectile brake (7) is pushed back and jams on a stopping cone (6). At the same time outlet (5a) of hollow needle (5) is cleared by the moving sliding sleeve (8). Thus, piston (2) may be driven by the gas propellant, thereby injecting the drug contained in drug chamber (14) and the hollow needle into the surrounding tissue of the animal through outlet (5a).Charging with the drug before firing is carried out by puncturing a silicon caoutchouc seal (3) with a hypodermic needle through a puncture opening (4) in casing (9), and then injecting the drug into drug chamber (14).
