    Abstract: A method for assisting a driver to drive a vehicle in a safer manner includes capturing images of road in front of the vehicle, and identifying a traffic sign in the images. A first image frame is captured at a first time and a second image frame is captured at a later second time when the images do comprise the traffic sign. A change in size or other apparent change of the traffic sign from the first image frame to the second image frame is determined, and conformity or non-conformity with a predetermined rule is then determined. The traffic sign can be analyzed and recognized to trigger the vehicle to perform an action accordingly when conformity is found. A device providing assistance with driving is also provided.

  • Publication number: 20190329029
    Abstract: A flexible thin film metal oxide electrode fabrication methods and devices are provided and illustrated with thin film polyimide electrode formation and IrOx chemical bath deposition. Growth factors of the deposited film such as film thickness, deposition rate and quality of crystallites can be controlled by varying the solution pH, temperature and component concentrations of the bath. The methods allow for selective deposition of IrOx on a flexible substrate (e.g. polyimide electrode) where the IrOx will only coat onto an exposed metal area but not the entire device surface. This feature enables the bath process to coat the IrOx onto every individual electrode in one batch, and to ensure electrical isolation between channels. The ability to perform selective deposition, pads for external connections will not have IrOx coverage that would otherwise interfere with a soldering/bumping process.

  • Patent number: 10097390
    Abstract: An implantable wireless device for transmitting data includes an external control device and an internal processing device. The external control device receives digital data and an alternating current carrier signal and uses the alternating current carrier signal to modulate the digital data into a phase shift keying modulation signal. The digital data have a plurality of time points that binary data change. The internal processing device includes a phase-lock loop (PLL)-based phase shift keying demodulator. The PLL-based phase shift keying demodulator obtains a ripple voltage signal according to the phase shift keying modulation signal. The ripple voltage signal decreases from a fixed voltage value at each of the plurality of time points and then increases to the fixed voltage value. The PLL-based phase shift keying demodulator demodulates the ripple voltage signal into the digital data.
