Abstract: This invention of an apparatus and a method for detecting luminescence from biological systems in response to magnetic fields measures the amount of light emitted when impressing a magnetic field on a living thing, a tissue or cells separated from a living thing to evaluate the effect of magnetic fields on biological systems. The apparatus of this invention consists of a dark box which shields a biological sample from external light, a magnetic field generator which is arranged adjacent to the biological sample to impress a magnetic field on it, and a photodetector which detects the light emitted from the biological sample exposed to the magnetic field from the said magnetic generator.

Abstract: An apparatus for controlling QoS of an ATM includes a first processing unit converting received AAL5-type traffic into AAL2-type traffic, and after that, serving real-time AAL2-type traffic with priority; and a second processing unit converting received AAL2-type traffic into AAL5-type traffic, and after that, serving real-time AAL5-type traffic with priority. Therefore, when a transmission link failure or traffic congestion is generated, real-time service traffic and non-real-time service traffic is segmented, and the real-time service sensitive for time delay is processed with priority and non-real-time service is delayed a little, thereby a limited bandwidth can be used effectively.

Abstract: A method of converting AAL2 cells that includes an original user data set into AAL5 cells and another method of converting AAL5 cells that includes an original user data set into AAL2 cells are disclosed. In the method of converting AAL2 cells, the length of the data subset included in each AAL5 cell generated is stored in a memory. Therefore, it is not necessary to store all the payloads of generated cells. When a last CPS packet is extracted, a total length of the original user data can be found using a set of lengths stored in the memory. As a result, the present invention requires only a small memory space, and any unnecessary delay problem is eliminated.

Abstract: The present invention relates to an AAL switch for multicast and a switching method for performing a flexible multicast connection. An AAL2 switch for multicast and a switching method for performing a flexible multicast connection can be used in applications like video conference and video on demand. An AAL2 switch can include a plurality of receiver circuits that convert an AAL2 packet into a CPS packet by demultiplexing, a plurality of storing devices that store a CPS packet separated from the AAL2 packet, and a plurality of transmitter circuits that periodically search the plurality of storing device and convert the searched CPS packet into an outgoing AAL2 packet by multiplexing. The transmitter circuits can transmit the outgoing AAL2 packet.

Abstract: A device for moving a radiator grille in automobiles is disclosed. In the device, a plurality of temperature sensors are placed in back of a radiator. The radiator grille has a plurality of directional control fins which are rotatable within a predetermined rotating angle by a fin moving means. The fin moving means is operated under the control of a control unit. The control unit outputs a control signal to the fin moving means in response to temperature signals from the sensors. The fin moving means rapidly moves the directional control fins under the control of the control unit in accordance with a temperature difference on the back surface of the radiator, thus controlling the flowing direction of air guided to the radiator. The radiator grille moving device of this invention improves the cooling effect of the radiator and improves durability of the parts, such as, an engine, arranged in back of the radiator.
