A compact and cost-effective infrared IFF alert system for small arm based on fiber-optical (FO) technology, comprising an optical interrogator and an optical transponder, is provided. The interrogator attached to a small arm, such as a rifle, includes a FO laser diode and FO receiver, which are connected to FO graded-index lens attached to sight of the small arm via a single-mode optic fiber, an electronic unit positioned in any convenient place of the small arm, and an alarm LED attached to the sight together with the lens. The transponder, which “a friendly target”—a soldier—is equipped with, contains a set of transmitter-receiver unit and an electronic unit that are mounted on a harness attached to soldier's helmet. This IFF system, when a friendly soldier is targeted, starts visual alarm signal for the shooter and sound signal for the “friendly target” so preventing “friendly fire”.

A vehicle operation assist system includes an assist yaw rate calculator which calculates a necessary moving amount to avoid an obstacle based on a detection result of the obstacle by a radar device, and a vehicle movement controller controls lateral movement of the vehicle based on the calculated moving amount. When an avoiding operation detector determines initiation of an obstacle avoiding operation by the driver, the vehicle movement controller operates a braking device to control the lateral movement of the vehicle, so that the obstacle can be reliably avoided. When a restoring operation detector determines initiation of a restoring operation, the vehicle movement controller operates a power steering device to control the lateral movement of the vehicle, so that delay in the steering operation by the driver, and excessive restoring operation of the steering handle to compensate for the delay are suppressed, thus stabilizing vehicle behavior. A vehicle operation assisting system capable of properly assisting in both an obstacle avoiding operation and a restoring operation by a driver is thereby provided.

It is possible to reliably avoid a problem that radiation irradiation does not stop even when an accumulated radiation dose reaches a target radiation dose. An AEC unit starts monitoring an integrated value of a radiation dose detection signal from a detection pixel and an output of an irradiation continuation signal at the same time, and continuously transmits the irradiation continuation signal in a predetermined period while the integrated value does not reach a threshold value. When the integrated value reaches the threshold value, the output of the irradiation continuation signal is stopped. The irradiation continuation signal is transmitted to an irradiation signal I/F of a radiation source control device through an irradiation signal I/F by wireless. The radiation source control device stops X-ray irradiation by an X-ray source when the irradiation signal I/F does not receive the irradiation continuation signal.

The sliding casing can be automatically positioned and locked in two directions; This design guarantees during processing the syringe after it is used, the pinhead is always protected by the sliding casing; The present invention also has a reliable function of auto-locking; Therefore, once the syringe is used, the plunger has been locked in the syringe barrel and can not be pulled out any longer; Any attempt to use the syringe again will cause the plunger broken and the syringe damaged, thus ensuring a one-time use.

In a radio communication system, a beam is formed between subscriber stations and a base station which has an antenna device with several antenna elements. The antenna elements emit a downlink signal based on respective weighing with coefficients of a weighting vector. A plurality of weighting vectors are determined at the subscriber station in an initialization phase and transmitted to the base station. In a subsequent working phase, the subscriber station selects a dominant weighting vector from the weighting vectors and transmits a designation of the selected weighting vector to the base station.

Single crystal composed of silicon with a section having a diameter that remains constant, are pulled by a method wherein the single crystal is pulled with a predefined pulling rate v_p having the units [mm/min]; and the diameter of the single crystal in the section having a diameter that remains constant is regulated to the predefined diameter by regulating the heating power of a first heating source which supplies heat to the single crystal and to a region of the melt that adjoins the single crystal and is arranged above the melt, such that diameter fluctuations are corrected with a period duration T that is not longer than (2·18 mm)/v_p.

An engine control apparatus and related control method for an engine are disclosed wherein cylinder discrimination is executed based on a crank signal and a cam signal under a normal signal mode. If a failure occurs in either the crank signal or the cam signal, the cylinder discrimination is executed based on a normal one of the crank signal and the cam signal. A starter device is driven to crank up the engine until judgment is made that the engine enters a running state. A duration time for the starter device to be driven is measured and if the duration time reaches a limit time, the driving state of the starter device is interrupted. When either the crank signal or the cam signal encounters the failure, the limit time is set to a longer time than a preset time for the normal signal mode.

When a congested state is detected with respect to a traffic processor, the ATM multiplexer performs a line changeover process so that at least a part of communication traffic to be processed by the traffic processing apparatus is processed by another traffic processing apparatus. This arrangement makes it possible to continue communication without causing a system down or call generation/reception limitation, even when traffic exceeds the maximum traffic which can be processed by the radio network system, thereby causing congestion.

For producing methanol from a synthesis gas containing hydrogen and carbon oxides the synthesis gas is passed through a first, preferably water-cooled reactor in which a part of the carbon oxides is catalytically converted to methanol, and the resulting mixture containing synthesis gas and methanol vapor is supplied to a second, preferably gas-cooled reactor in which a further part of the carbon oxides is converted to methanol. The mixture withdrawn from the first reactor is guided through a gas/gas heat exchanger in which the mixture is cooled to a temperature below its dew point. Subsequently, methanol is separated from the gas stream in a methanol separator and withdrawn, while the remaining gas stream is supplied to the second reactor.
