  • Patent number: 11950491
    Abstract: A semiconductor mixed material comprises an electron donor, a first electron acceptor and a second electron acceptor. The first electron donor is a conjugated polymer. The energy gap of the first electron acceptor is less than 1.4 eV. At least one of the molecular stackability, ?-?*stackability, and crystallinity of the second electron acceptor is smaller than the first electron acceptor. The electron donor system is configured to be a matrix to blend the first electron acceptor and the second electron acceptor. The present invention also provides an organic electronic device including the semiconductor mixed material.

  • Patent number: 9142671
    Abstract: The invention provides a lateral double-diffused metal oxide semiconductor (LDMOS). The pre-metal dielectric layer (PMD) of the LDMOS is a silicon rich content material. Additionally, the inter-layer dielectric layer (ILD), inter-metal dielectric layer (IMD), or protective layer of the LDMOS may be formed of a silicon rich content material.

  • Patent number: 9045139
    Abstract: An intuitive eco-driving assistance system is mounted on a vehicle and has an input module, a control module and an output module. The control module is electrically connected to the input module and the output module. The output module acquires images ahead of the vehicle and speed signals for the control module to recognize a speed limit, traffic lights and a speed and distance of any obstacle on the images. Furthermore, according to the driving limits of the road and actual vehicle speed, the output module prompts for an eco-driving instruction and the speed limit meeting the road condition visually or audibly. Accordingly, the issue of conventional vehicles being structurally complicated and costly for conserving energy, only passively prompting fuel consumption, and consuming more fuel can be solved without requiring any additional and complicated system.
