摘要： A signalling system is provided which can be used to update the prices of goods which are electronically displayed on supermarket shelves (1). The signalling system comprises a first signalling device having an input terminal for receiving electrical message data received from a central computer system (5), a spread spectrum encoder for encoding the received message data and an electroacoustic converter (11) for converting the encoded data into corresponding acoustic signals and for transmitting the acoustic signals into a transmission medium. The signalling system also comprises a second signalling device (3) having means for receiving acoustic signals from said transmission medium and for converting the received acoustic signals into corrresponding electrical signals, a spread spectrum decoder for decoding the received signals and a message regenerator for regenerating the message data transmitted by the first signalling device from the signals output by the decoder.

摘要： Double-stranded nucleic acid is denatured to form single strands by brief contact with a tetrafluoroethylene-perfluoro-2-(fluorosulphonylethoxy) propylvinyl ether, e.g. NAFION. This may be a preliminary step in a hybridisation assay or a nucleic acid amplification.

摘要： Intracellular material is released from bacterial, yeast, plant, animal, insect or human cells by the application of a low voltage such as 1 to 10 V to a suspension containing the cells. The conditions may be selected such that DNA released from the cells is electrochemically denatured so as to be available for use in an amplification procedure.

摘要： A magnetostrictive element, which may be of rectangular shape, is positioned next to a hard magnetic biasing element field patterns recorded therein which bias the magnetostrictive element to resonate at selected frequencies, particularly harmonics of the fundamental frequency, in response to an alternating interrogating magnetic field at the same frequencies. Data may thus be encoded by selecting the frequencies at which the element will resonate. In addition to resonance at different harmonics, resonance in different modes, particularly longitudinal, transverse or flexural modes may be produced. The device may be applied to article identity systems, such as security systems but also has many other applications.

摘要： In an apparatus for indicating the angular position of a rotatable member, a drive coil (51) is provided with its axis corresponding to the axis of rotation of the rotatable member. A coil (65) is wound around the rotatable member, and a capacitor (66) is provided in the coil (65) to form an LC resonant circuit. The coil (65) on the rotatable member is wound so that application of an alternating magnetic field to the drive coil (51) induces a resonance in the LC circuit which is constant for all angular positions of the rotatable member. Pick-up coils (53, 55) are provided such that the planes of these coils and the drive coil (51) are orthogonal. The resonance of the LC circuit produces signals in the output coils (53, 55) which depend upon the angular position of the rotatable member. The signals may be processed to determine that angular position, and the processing is simplified with this arrangement of output coils since the signals produced therein are quadrature signals.

摘要： A magnetic flow meter (20) includes a cylindricaL vessel (34) within which electrodes (42) are placed directly opposite each other about a magnetically permeable core (44). In that way, two flow channels are obtained in the vessel. A common magnetic field is applied across both flow channels. The magnetic flow meter (20) is used in conjunction with a controller (100) which monitors amplitude modulated signals representative of applied magnetic field and induced electric field. These amplitude modulated signals are passed to Sigma-Delta modulators, which directly digitise the amplitude modulated AC signals into digital pulses. The controller is capable of monitoring reverse flow through the meter, and to store results until forward flow resumes. Moreover, the controller generates a driving signal for coils (64) which generates a magnetic field, the coil being placed in conjunction with a capacitor (416) which causes resonance. This reduces power consumption by the coil in driving the meter.

摘要： There is described a process for generating a number representative of an analogue data source in which during enrolment a distinctive characteristic of the analogue data source is measured to obtain physical data. Part of the physical data is used to generate a physical value which is representative of the analogue source. An error correction algorithm is applied to the physical value to generate error correction data, which is then transformed, using another part of the physical data, to generate transform data. During subsequent regeneration of the physical value, the distinctive characteristic is re-measured to generate a new set of physical data, and a physical value is generated using the same part of the physical data as was used during enrolment. Error correction data is then generated by transforming the transform data, using an inverse transform to that used during enrolment, using the same part of the physical data as was used to transform the error correction data during enrolment. The regenerated error correction data is then used by the error correction algorithm to correct errors in the physical value representative of the analogue source. By using part of the physical data set to transform the error correction data and then storing the resulting transform data, the security of the original physical data is improved.

摘要： A check weighing system is provided which can check weigh samples (1) on a production line. The check weighing system comprises a magnet (13) for creating a static magnetic field over an interrogation zone for creating a net magnetisation within a sample (1) located within the interrogation zone and an RF coil for applying an alternating magnetic field over the interrogation zone for causing excitation of the sample (1) within the interrogation zone according to the principles of NMR. The check weighing system also comprises a sensor for sensing the energy emitted as the sample relaxes back to an equilibrium state after excitation as the samples pass through the interrogation zone on a conveyor belt (9) forming part of the production line. The sensed signal from the sample (1) is then compared with calibration data which is obtained for at least one similar sample of known mass, which calibration data relates the mass of the similar sample to the corresponding signal output by the sensor, to provide the indication of the mass of the sample.

摘要： There is disclosed a vehicle (1) for travelling over snow or the like and comprising a straight runner means (19) and one or more curved runners (21, 23, 25) convex towards the straight runner means. When the vehicle is level it travels on the straight runner means in a straight line. By rolling the vehicle to one side, one of the curved runners engages the snow and the vehicle performs a carving turn whose radius is determined by the radius of the runner. Different turn radii are selectable by altering the roll angle of the vehicle. Embodiments are described for use on snow and ice and a wheeled version for use on hard surfaces is also disclosed.
