  • Publication number: 20250199103
    Abstract: A computer-implemented method and system for performing magnetic resonance diffusion weighted imaging of an object includes generating, via a processor, a diffusion weighted imaging sequence where all diffusion gradients are allocated into N groups such that all imaging slices are acquired for all the diffusion gradients corresponding to a group of the N groups back-to-back in An*TR, wherein N is two or larger, wherein An is a number of diffusion gradients of each group of the N groups and TR is repetition time, and wherein in each TR every diffusion gradient of the group of the N groups is applied at least once. The computer-implemented method and system also includes acquiring, via the processor, imaging slices for multiple groups of the N groups utilizing the diffusion weighted imaging sequence during a scan of the object utilizing a magnetic resonance imaging scanner.

  • Patent number: 10247795
    Abstract: A method that includes deriving a first power spectral density function of a signal input to a ripple cancellation filter; deriving a second power spectral density function of a signal concurrently output from the ripple cancellation filter; frequency shaping the first power spectral density according to a spectral rejection image of the ripple cancellation filter to obtain a test power spectral density; and indicating a degraded performance of the ripple cancellation filter in the event that the test and second power spectral density functions fail to match within pre-determined criteria.

  • Patent number: 10185141
    Abstract: The present disclosure presents techniques to facilitate improving operation of an electrical system, which includes a bus structure that cascades multiple electrical devices. The bus structure includes a first outer conductive layer implemented as a positive layer; a second outer conductive layer implemented as a negative layer; a first intermediate conductive layer neighboring the first outer conductive layer; a second intermediate conductive layer neighboring the second outer conductive layer; and a third intermediate conductive layer neighboring the second intermediate conductive layer, in which the third intermediate conductive layer is implemented as an inter-device layer that facilitates electrically coupling at least two of the electrical devices in series.

  • Patent number: 10141909
    Abstract: An apparatus includes a self-coupled transformer, a first band stop filter and a tank circuit connected in series with the first band stop filter between first and second windings of the self-coupled transformer. An inductor of the tank circuit acts as an out-of-phase third winding of the self-coupled transformer.

  • Patent number: 10132852
    Abstract: An apparatus that includes a power amplifier; a load that is operatively connected to be electrically driven from the power amplifier; and an impedance monitor that is configured to in real-time identify a favorable segment within an output waveform of the power amplifier, model the baseline power spectral density of a load driven by the power amplifier during the identified segment of the output waveform, sample an empirical power spectral density of the load during the identified segment of the output waveform, and indicate a load fault in the event that the empirical power spectral density deviates from the baseline power spectral density beyond at least one pre-determined error criteria.

  • Publication number: 20070251083
    Abstract: The present subject matter includes method and apparatus for an insulating layer applied to a battery to effectively increase the insulated separation between the anode and cathode contact surfaces of the battery. This increase in effective separation between anode and cathode decreases the probability that moisture applied to the battery will cause substantial ohmic conductivity between the anode and the cathode. Consequently, fewer batteries will be prematurely depleted or destroyed by moisture and fewer devices holding those batteries will need repair. The present subject matter serves to prevent or eliminate discharge of corrosive battery chemicals due to moisture and operating in wet environments. The life of batteries and devices using the present subject matter is thus extended. Additional method and apparatus can be found in the specification and as provided by the attached claims and their equivalents.
