  • Automatic wiper-controlled vehicle headlamps
    Patent number: 5519257
    Abstract: A method for automatically controlling headlamps in response to windshield wiper controls is provided. A microcontroller senses the voltage levels of signals from a windshield wiper switch and a headlamp switch. If the microcontroller senses that the vehicle operator has turned on the windshield wiper switch, the microcontroller turns on the headlamps of a vehicle unless the windshield wipers are in intermittent mode or the operator of the vehicle has turned off the headlamps within a predetermined period of time.

  • Process for making silk fibroin fibers
    Patent number: 5252285
    Abstract: The present invention relates to a process for spinning silk fibers. The process involves dissolving silk fibroin in an aqueous salt solution, removing the salt from the solution, followed by removal of the water to form a regenerated silk material. The silk material is then dissolved in hexafluoroisopropanol to form a fiber-spinnable solution.
