Abstract: A needleless injection device includes an initiator valve controlling flow of compressed gas into a reservoir. A poppet valve connecting to the reservoir has a gas pressure regulation end to regulate flow from the initiator valve into the reservoir. A clamp piston is driven forward by gas pressure from the reservoir and causes jaws to clamp onto a plunger extending into an ampule. The poppet valve opens when reservoir pressure reaches the cracking pressure of the poppet valve. Gas from the reservoir rushes through the poppet valve into a drive chamber and forces a drive piston, containing the clamp piston and jaws, forward causing the plunger to slide into the ampule. A jet of injectant is discharged from the nozzle of the ampule and penetrates through the patient's skin. An improved method of needleless injection uses a specific pressure profile, ampule nozzle diameter, patient, injection site, and injectant parameters.

Abstract: Method for generating an FDM signal with a high channel number for transmission purposes in radio and television distribution systems. The channel signals which are sampled at a uniform sampling rate and digitised are respectively frequency-converted in interpolating digital frequency converters with an increase in the sampling rate and are combined to form the FDM signal. The frequency-converted signals are signals which have complex values and are combined by means of a complex adder and subjected to frequency conversion in a second stage by means of filters having coefficients with complex values, the sampling rate being further raised, and are converted into real signals which are combined to form the FDM signal by means of a real adder. The method is characterised in that for the purpose of separating the individual channel signals or channel bundle signals from the FDM signal, the method steps applied to condition said signal are subjected to a Hermite transposition and applied. Use in a radio and television distribution system, in particular in the case of optical fibres, which permits a high channel number and a local exchange of programmes in conjunction with high flexibility and reconfigurability at arbitrary points by means of inexpensive single-channel bandpass filters. <IMAGE>

Abstract: This invention relates to a method for the detection of rare events which are events occurring at a frequency of less than one in 10⁴. It is particularly useful in detecting events at frequencies of one in 10⁵ and one in 10⁶. The method employs one or more first markers that are specific for the rare event particle each of which are labelled with a dye having an emission wavelength distinguishable from the other(s). The method further employs one or more second markers that are specific for a majority of the remainder of the particles present in the cell sample but are negative for the rare event particle. The second markers all are labelled with the same dye. The second markers are collectively referred to as the exclusion color. By analyzing the particles for the presence of the first marker(s) and the absence of the second markers, rare events can be detected.
