  • Publication number: 20240072203
    Abstract: A method for fabricating light emitting diode (LED) dice includes the steps of: providing a substrate, and forming a plurality of die sized semiconductor structures on the substrate. The method also includes the steps of providing a receiving plate having an elastomeric polymer layer, placing the substrate and the receiving plate in physical contact with an adhesive force applied by the elastomeric polymer layer, and performing a laser lift-off (LLO) process by directing a uniform laser beam through the substrate to the semiconductor layer at an interface with the substrate to lift off the semiconductor structures onto the elastomeric polymer layer. During the laser lift-off (LLO) process the elastomeric polymer layer functions as a shock absorber to reduce momentum transfer, and as an adhesive surface to hold the semiconductor structures in place on the receiving plate.

  • Publication number: 20240043849
    Abstract: Modified viral genomes are able to reduce induction of inflammatory and immune antiviral responses. This manifests itself in reduced NF-kB activity, increased viral transduction rates, and increased expression of transgenes. Viral genomes are modified by incorporating one or more oligonucleotide sequences which are able to bind to TLR9 but not induce activation of it. The oligonucleotide sequences may be synthetic, bacterial, human, or from any other source.

  • Patent number: 11796411
    Abstract: A sensor includes a housing having a accommodating room, a flexible plate provided in the accommodating room and moveable to induce a medium pressure change in the accommodating room, and a pressure sensing component for sensing the pressure change. The pressure sensing component and the flexible plate are assembled and moveable together. In the sensor of the present invention, after an external signal to be sensed is transmitted to the sensor, the flexible plate moves to induce air disturbances, and then the pressure sensing component receives a pressure change induced by the air disturbances and performs signal sensing. Compared with the conventional sound sensor, the sensor of the present invention provides no opening communicating with the external environment. Therefore, the impact of foreign objects, noise and other environmental factors on the sensor can be avoided, and the signal generated by the object not to be sensed can be effectively reduced.
