摘要： A medical magnetometer (10) comprising one or more induction coils (2) for detecting a time varying magnetic field of a region of a subject's body, such as the heart. Each coil has a maximum outer diameter of 4 to 7 cm, and a configuration such that the ratio of the coil's length to its outer diameter is at least 0.5, and the ratio of the coil's inner diameter to its outer diameter is 0.5 or less. Each induction coil (2) is coupled to a respective detection circuit comprising a low impedance pre-ampiifier (3), a low pass filter (5), a notch filter (6) to remove line noise, and an averaging element (7). Each detection circuit produces an output signal (9) for use to analyse the time varying magnetic field of the region of the subject's body.

摘要： A method for allowing a first party and a second party to obtain shared secret information is provided. The method comprises the steps of: obtaining, by the first party, a sequence of values A=X+NA where X is a sequence of values and NA is a random sequence associated with the first party; obtaining, by the second party, a sequence of values B=X+NB where NB is a random sequence associated with the second party; performing, by the first and second parties, a data matching procedure to identify corresponding pairs of values, a, b, in respective sequences A and B that match, wherein sequences A and B are discrete-valued sequences equal to, derived from, or derived using, sequences A and B; wherein the shared secret information is equal to, or derived from, or derived using, the matching values in sequences A and B.
