  • Publication number: 20250082252
    Abstract: The current innovation pertains to the medical data processing domain and introduces a method for formulating an iNPH prediction model using a new/old stimulus BCI paradigm. The process involves conducting new/old stimulus BCI paradigm experiments on a target population both before and after the Lumbar Tap Test, obtaining electroencephalogram (EEG) signal data. After preprocessing the EEG signal data, the model extracts features related to new and old stimulus event-related potentials before and after the test, specifically focusing on P600 amplitude features. The iNPH prediction model is then trained based on these event-related potential features. This innovation facilitates quantifying cognitive function improvement, aiding physicians in prompt iNPH diagnosis and enabling timely and effective patient treatment.

  • Publication number: 20100280676
    Abstract: Connecting a load device to a power supply is described. A connection to a load device is detected on a communication link, where the load device is in a first power state. In response to detecting the connection to the load device, a bias power source is enabled to supply bias power on the communication link to the load device. Power information of the load device is received over the communication link. Power is supplied to the load device, based on the power information, to place the load device in a second power state.
