Abstract: An omnidirectional antenna includes one or more dipole radiators (20). Each dipole radiator comprises a first (24) and second cylindrical radiating element (32). Each radiating element (24, 32) includes an end plate (26, 34) for mounting the radiating element coaxially on a tubular mast (22). The cylindrical radiating elements (24, 32), end plates (26, 34) and tubular mast (22) are all DC connected. A feed line (40) is provided which may extend through the center of the mast (22) and exit at an opening (34A) for connection to a secondary feed line. The secondary feed line is connected to an end of one of the cylindrical radiating elements of each pair of elements for each dipole radiator. The feed line (40) is connected to the end of the cylindrical radiating element (24) opposite the end plate (26). The configuration of the dipole radiators is such that the radiator functions as an RF choke for the adjacent radiators. An additional single cylindrical element can be provided at the end of a plurality of dipole radiators to provide RF choking for the immediately adjacent dipole radiator. A plurality of main feed lines may be included to extend through the center of the mast with corresponding openings for connection to secondary feed lines.

Abstract: The invention relates to a mould closing device for an injection moulding machine, having at least one injection mould, a first injection mould half being displaceable on a first fixed platen and a second injection mould half being displaceable on a mould support plate which can be moved on at least two tie bars between the first fixed platen and a second fixed platen, displacing being carried out by means of at least one long-stroke driving cylinder/piston mechanism for rapid opening and closing of the injection mould halves concerned and the injection mould halves concerned being closable under high pressure by means of short-stroke pressure pad mechanism, and having coupling bars which can be moved radially with respect to the longitudinal axis of the pressing ram of the pressure pad mechanism. 
<??>In order to simplify the design of the mould closing device and to improve it to the extent that the cycle times of the injection operations and the energies to be expended during closing and opening of the injection mould halves are minimised, it is proposed that the cylinder of the pressure pad mechanism is arranged at or in the second fixed platen and the ram of the pressure pad mechanism is an annular piston having at least one clearance in its inner skirt, and that in the piston cavity there is a rod mounted axially movably, which is firmly connected to the movable mould support plate and has coupling bars which can swing radially in and out of the clearance(s).

Both sides of the partition support a plurality of edgewise connectors, stacked one over the other, for accepting the plug-in expansion circuit boards. The vertical partition connectors are electrically connected to the permanently mounted connector such that when the carrier is in position within the housing all of the mated expansion boards are electrically operable and connected to the existing system.

Abstract: A current-to-frequency converter 12′ (Figure 3) for use with an accelerometer 10 comprises a storage capacitor 13 which receives the accelerometer current and develops a charging voltage, reset charging means 25 which delivers timed charges to offset the voltage by predetermined amount and voltage sensing means 14′ which senses the charging voltage reaching positive or negative thresholds in order to initiate a reset and offsetting the voltage. The polarity of charging voltage at which reset is triggered determines that polarity threshold as being half the magnitude of the offset voltage but the opposite polarity threshold of greater magnitude so that the voltage on the reset capacitor avoids it. If the acceleration current direction changes altering the charging voltage polarity the first reset at this high magnitude threshold existing for that polarity causes it to adopt the lower magnitude of half the reset offset voltage for subsequent resets and the opposite polarity adopt a threshold of the greater magnitude.

Abstract: An image-coding system reduces image data redundancies and perceptual irrelevancies through progressive sub-band coding. The image is separated into plurality of sub-bands ((0,0) to (3,3)). From this sub-band information, a perceptual metric, based on the properties of the sub-band filters, quantizer error distribution, and properties of the human visual system, is determined (28) which provides the maximum amount of coding noise that may be introduced to each pixel in every sub-band without causing perceptible degradation of the coded image. This perceptual metric is used to adjust the quantizer (25) used in encoding each sub-band signal. In addition, redundancy in the output of the quantizer is reduced using a multidimensional Huffman compression scheme (27).

Abstract: A method of traffic monitoring is described which comprises forming at least first and second scene images of a scene in which traffic may be present, the images being formed at instants of time separated by a time interval. At least one of the first and second scene images is processed to form an edge image representing the occurrence of edges in the scene, and a determination is made on the basis of the edge image of the presence or absence, and spatial location, of traffic in the scene. A difference image is formed in which each pixel represents the difference between the intensity of the pixels of the first and second scene images at the corresponding point in the image, and a determination is made from the distribution of pixels of different intensities in the difference image of the presence or absence of movement in the scene.
