  • Patent number: 11979980
    Abstract: A first and second patterned circuit layer are formed on a first surface and a second surface of a base material. A first adhesive layer is formed on the first patterned circuit layer. A portion of the first surface is exposed by the first patterned circuit layer. The metal reflection layer covers the first insulation layer and a reflectance thereof is greater than or equal to 85%, there is no conductive material between the first patterned circuit layer and the metal reflection layer, and the first adhesive layer is disposed between the first patterned circuit layer and the first insulation layer. A transparent adhesive layer and a protection layer are formed on the metal reflection layer. The transparent adhesive layer is disposed between the metal reflection layer and the protection layer. The protection layer comprises a transparent polymer. The light transmittance is greater than or equal to 80%.

  • Publication number: 20240138709
    Abstract: A care system monitoring method for sensing the movement state of a bedridden person is provided. The care system monitoring method includes the following stages. Initial-state information is sensed. A first warning signal is issued to remind the caregiver to perform a movement action on the bedridden person when the time that the bedridden person has been in the initial state exceeds the threshold period. First-state information (which is information that is collected when the bedridden person is in the first state) is sensed after completing the movement action. It is determined whether the bedridden person was moved correctly according to the initial-state information and the first-state information. The first-state information is reset as the initial-state information if it is determined that the bedridden person has been moved correctly. A second warning signal is issued if it is determined that the bedridden person has been moved incorrectly.

  • Publication number: 20240123479
    Abstract: A recycling apparatus for a solar cell module includes a platform for supporting and positioning the solar cell module, and at least one milling device disposed on the platform and having a milling member configured to contact a back plate of the solar cell module, and a casing defining a chip-receiving space and having an air inlet and a suction port communicating with the chip-receiving space. A drive device is connected to the at least one milling device for driving the at least one milling device to move around and mill the solar cell module through the milling member.

  • Patent number: 11937370
    Abstract: A base material is provided. A first patterned circuit layer and a second patterned circuit layer are formed on a first surface and a second surface of the base material. A first insulation layer and a metal reflection layer are provided on the first patterned circuit layer and a portion of the first surface exposed by the first patterned circuit layer, wherein the metal reflection layer covers the first insulation layer, and a reflectance of the metal reflection layer is substantially greater than or equal to 85%, there is no conductive material between the first patterned circuit layer and the metal reflection layer. A first ink layer is formed on the first insulation layer before the metal reflection layer is formed.
