  • Patent number: 12290372
    Abstract: A system and method is operable to automatically determine the amplitude and latency of one or more evoked potential (EP) or event-related potential (ERP) from electroencephalography (EEG) data. The EEG data from an EEG scan is separated into one or more epochs containing the desired EP or ERP waveforms. Epochs corresponding to the same type of EP or ERP such as N100, P300, and N400 are averaged automatically. The averaged epochs are automatically filtered in the time-frequency domain using an automatically selected filtering mask associated with the type of EP or ERP. A corresponding peak is automatically identified from the filtered epoch, in which the amplitude and latency is automatically measured.

  • Patent number: 12259576
    Abstract: Depositing a side slab structure on a cladding layer before etching a supporting dielectric prevents tapering of a silicon waveguide during etching of the supporting dielectric and a substrate. For example, the side slab structure may be deposited over the silicon waveguide and the cladding layer after etching the cladding layer. As a result, when an electronic device is integrated ex situ on the substrate, wave intensity and/or total internal reflection is improved, which improves an efficiency of the electronic device.
