    Abstract: Disclosed is a method of manufacturing an organic semiconductor thin film, including preparing semiconductor ink containing a solvent, a low-molecular-weight organic semiconductor and a high-molecular-weight organic semiconductor and forming an organic semiconductor thin film vertically phase-separated by applying the semiconductor ink on a substrate through a bar-coating process using a bar. In the bar-coating process of the invention, the semiconductor ink blend is used, and the gap between the substrate and the bar is adjusted, thus controlling vertical phase separation. Also, the speed of the bar, the gap of which is adjusted, is regulated, thus controlling crystal growth, whereby the uniformity of the thin film is improved and thus a high-quality organic semiconductor crystalline thin film having a large area can be manufactured in a continuous process.

  • Dynamic fishing lure system and method
    Patent number: 10588299
    Abstract: A fishing lure representing a typical fish is formed from plastic or polymer. Embedded therein is provided a dynamic motion actuator utilized to attract fish by the continuous or random motion effected thereby. The device is powered by an onboard battery connected to a vibrational motor. A control circuit detects the water activation of the fishing lure and enables the motor and a lighting system for a predetermined sequence of activation and deactivation. An auxiliary control circuit senses connection of a USB to barrel connector power wire through a charging dock mounted in the frame of the fishing lure. Checking both a charging state and the number of times the device has been charged, the auxiliary control circuit enables a steady state light for signaling charging and a flashing light if the number of charges is above a certain level by using a counter.
