  • Patent number: 11616377
    Abstract: 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 which bypasses said energy storage device; an inductor provided between the positive terminal and the output of the switching network; and a controller arranged to monitor the voltage across the inductor and arranged to control a duty cycle of the switching circuit based on the magnitudes of voltage changes detected across the inductor. By monitoring and analysing the magnitude of voltage changes across the inductor, the controller determines the states of charge of other series connected smart cells without any communication between cells.

  • Patent number: 11592241
    Abstract: Apparatus and methods for jet impingement cooling are provided. In one arrangement, a fluid channelling structure engages against a target surface to define a flow volume. Fluid is jetted onto the target surface from inlets and is removed via outlets. Flow directing features form a plurality of channels with no straight paths between inlets and outlets. A time averaged flow direction of fluid in contact with each flow directing feature is more nearly perpendicular to a direction of jetting of the fluid from a nearest inlet than parallel to the direction of jetting One or more pairs of the inlets and outlets are such that a majority of fluid jetted onto the target surface from the inlet of the pair will be removed from the flow volume through the outlet of the same pair.

  • Patent number: 11580432
    Abstract: System monitors and methods of monitoring a system are disclosed. In one arrangement a system monitor predicts a future state of a system. A data receiving unit receives system data representing a set of one or more measurements performed on the system. A first statistical model is fitted to the system data. The first statistical model is compared to each of a plurality of dictionary entries in a database. Each dictionary entry comprises a second statistical model. The second statistical model is of the same general class as the first statistical model and obtained by fitting the second statistical model to data representing a set of one or more previous measurements performed on a system of the same type as the system being monitored and having a known subsequent state. A prediction of a future state of the system being monitored is output based on the comparison. The first statistical model and the second statistical model are each a stochastic process or approximation to a stochastic process.

  • Patent number: 11543377
    Abstract: A probe comprises a resistive element configured to be brought into thermal contact with an entity to be sensed. A measurement system applies a plurality of heating pulses to the resistive element by driving an electrical current through the resistive in element and measures an electrical response of the resistive element to the heating pulses in order to determine information about either or both of the composition and state of the entity. The measurement system generates an output signal using the measured electrical response, wherein the output signal is generated by progressively offsetting the measured electrical response such that, in the event of an average temperature of the resistive element changing between different heating pulses due to a drift in the average temperature of a portion of the entity being sensed, a variance over the plurality of heating pulses of a value of the output signal at a predetermined common reference point within each heating pulse is reduced.

  • Patent number: 11490815
    Abstract: Described herein are methods and systems for extracting or determining subject motion from multi-channel electrical coupling in imaging of the subject, in particular in magnetic resonance (MR) imaging of the subject. The motion can be of a region of interest of the subject (such as an organ or specific tissue). Changes in the position of the subject and the subjects organs can be monitored by measuring how external coils, such as RF coils, couple to the subject and to one another and change the scattering of the RF coils, for example scattering of RF pulses transmitted by the coils. Changes in position influence this coupling and the scattering and can be detrimental to the quality of the imaging The present methods and systems address and overcome this problem.
