    摘要: In an optical fiber FDM system, the carriers are derived from the output of a high quality Master Oscillator, which output at frequency f.sub.0 is applied to a Raman Nath modulator (RNM1) whose other input is a frequency f.sub.0 this gives as its outputs (assuming a five channel system) f.sub.0 -2f, f.sub.0 -f, f.sub.0, f.sub.0 +f and f.sub.0 +2f. These are modulated by modulators (CM1, to CM5) with the signals to be sent, and the modulation results combined in a combiner CB for transmission to a remote station. The oscillator output is also sent to the remote stations where it is frequency-shifted by a Bragg modulator (BM) and the resultant similarly dealt with by a Raman Nath device (RNM2) to give five frequencies which are used to demodulate the channels. In an alternative the channel frequencies are switchable.

    摘要: A data transmission system, for interconnecting a number of relatively closely-spaced user nodes, e.g. data terminals in a computer system, uses a passive bus terminated at each end by resistive terminations (T), which bus interconnects a number of system nodes (N). The nodes are identical and there is no central control to the system. To maintain synchronism between the nodes, there is a clock/sync. pulse circuit (CSS) connected to the mid-point of the bus. This enables the use of a bit rate of twice what would be possible if the source were connected to one end of the bus due to the reduced clock pulse skew effect.

    摘要: A time division multiplex system which has a total bandwidth of 64Kbit/s and has this bandwidth split up into 80 channels each of 800 bits/sec. Three speech channels are provided, each using 20 of these channels, 12 channels are used to provide a 9.6Kbit/s data channel, 4 are used to provide for 50-110 baud start-stop channels and another 4 are used to provide a 3.2Kbit/s signalling channel.To provide fast sync, a sync pattern consisting of two sync words and a channel number is sent at the same time on all of the channels, and the receiving side monitors for the 19th channel. When it finds what is coming in at the time, it first achieves bytes alignment between the received byte stream and the local byte stream, then it checks the respective channel numbers. The difference between them gives an offset which is used to adjust the demultiplexing logic.

    摘要: A needle-less injector device for delivering a dose of fluid intradermally, subcutaneously or intramuscularly to an animal or human. The device includes an inner housing having opposed ends. A syringe is disposed in one end of the inner housing. The syringe includes a nozzle for delivering a dose of fluid held within the syringe. A plunger is movably disposed within the syringe. A spring powered hammer is movably disposed within the inner housing. The hammer cooperates with the plunger to drive the dose of medicament from the nozzle. An injection delivery spring for powering the hammer is positioned and compressed between the other end of the inner housing and the spring powered hammer. An outer housing slideably supports the inner housing. A skin tensioning spring is mounted between the inner housing and the outer housing, the skin tensioning spring biasing the nozzle of the syringe against the animal or human. A trigger mechanism is disposed in the outer housing, the trigger mechanism cooperating with the spring powered hammer to release the injection delivery spring, wherein the size of the injection delivery spring and the length of the hammer dictate the amount of dose delivered and whether the dose is delivered intradermally, subcutaneously or intramuscularly to an animal or human.

The inner housing supporting a vial that includes a nozzle for delivering a fluid held within the vial. A spring powered ram that is adapted for pushing a seal and plunger is mounted within inner housing. A skin tensioning spring mounted between the inner housing and the outer housing is used for pushing the leading end of the inner housing away from the outer housing. A trigger that cooperates with the spring-powered ram is used to release the ram from the cocked position only when the inner housing is in a firing position.
