    摘要: A method of performing a multiplication operation in the optical domain using a device (100) comprising: an optical waveguide (101), and a modulating element (102) that is optically coupled to the optical waveguide (101), the modulating element (102) modifying a transmission, reflection or absorption characteristic of the waveguide (101) dependant on its state, wherein the state of the modulating element (102) is adjustable by a write signal (103). The method comprises: encoding a first value to the write signal (103), using the write signal (103) to map the first value to a state of the modulating element (102); encoding a second value to a read signal (104); producing an output signal intensity as the transmitted or reflected read signal, wherein the product of the first value and the second value is encoded in the output signal intensity.

    摘要: A system for diagnosing a heart condition comprises an imaging system (102) arranged to acquire two images of the heart at respective points in the cardiac cycle, and locating means, which may be manually operated or automatic, for locating a series of pairs of points on the images. Each pair of points indicates the respective positions of a single part of the heart in the two images. The system further comprises a processor (108) arranged to calculate from the positions of said pairs of points a value of at least one parameter of the deformation of the heart. It may further be arranged to compare the value of the at least one parameter with reference data to generate a diagnostic output.

    摘要: A smart cell, comprising: a positive terminal; a negative terminal; a switching circuit which is arranged to select between a first switching state in which an energy storage device is connected between the positive terminal and the negative terminal and a second switching state in which bypasses said energy storage device; and an inductor provided between the positive terminal and the negative terminal. The inductor provides a means by which to monitor current changes in the rest of the circuit. The inductor can thus be used to detect current changes as seen by the smart cell and this sensed information can be used to control the smart cell, e.g. to control an energy source (energy storage device) that forms part of the smart cell. As the inductor is part of the smart cell, it forms part of a decentralized controller strategy to regulate the state of charge of cells within a larger system. For example, it may form part of a decentralized controller strategy to regulate the state of charge of serially connected cells of varying capacities.
