  • Patent number: 11414658
    Abstract: A tracer particle is provided. The tracer particle includes: a core structure; a nucleic acid molecule immobilized on the core structure; and a shell layer covering the core structure and the nucleic acid molecule; wherein the core structure has a first porosity, the shell layer has a second porosity, and the first porosity is greater than the second porosity.

  • Publication number: 20210078089
    Abstract: A post 22D may be disposed between holders 22H. Post 22D preferably does not extend from panel 22 as much as holders 22H. Post 22D may have a protrusion 22DD. Pushstick 70 may also have a detent or protrusion 70D extending therefrom. Preferably protrusion 70D moves past protrusion 22DD as pushstick 70 is moved along posts 22HP. Protrusions 70D and 22DD may contact, preventing pushstick 70 from moving along panel 22. Persons skilled in the art will recognize that protrusions 70D and/or 22DD may engage notches in panel 22 and/or pushstick 70, respectively. Persons skilled in the art will recognize that the interaction of protrusions 70D and/or 22DD can be used instead or in conjunction with the friction-based retaining arrangement, i.e., where friction is created between narrow area 71N and post 22HH, discussed above. Holders 22H and/or post 22D are preferably integrally molded with panel 22. Accordingly, pushstick 70 may be held unto the panel 22 without requiring any additional parts.

  • Publication number: 20150078609
    Abstract: A vent structure for electro-acoustic product includes a plastic member shaped like a tube and defining an opening, and a ventilation layer bonded to the plastic member using an insert molding technique and fully covered over the opening. Thus, the ventilation layer of the vent structure is more moisture-heat resistant in the environment and will not drop from the plastic member easily.

  • Patent number: 7400373
    Abstract: A liquid crystal display (LCD) panel has a structure in which one of the thin film transistor (TFT) substrate and the color filter (CF) substrate has an indented pattern surface to contact or surround the end of the spacer, such that the friction between the spacers and indented pattern surface can be reduced, thus shifting of spacer to a wrong position can be avoided. A method of manufacturing such LCD panel is also disclosed.
