  • Publication number: 20240134167
    Abstract: An optical path folding element includes a main body, a light absorption film layer and a matte structure. The main body has optical surface including an incident surface, a reflective surface and an emitting surface. A light enters into the optical folding element through the incident surface. The reflective surface reflects the light so as to change a traveling direction thereof. The light exits the optical folding element through the emitting surface. The light absorbing film layer is configured to reduce reflectance and provided adjacent to at least part of the optical surface, and the light absorbing film layer is in physical contact with the main body. The matte structure is disposed adjacent to at least part of the optical surface. The matte structure provides an undulating profile on a surface of the optical path folding element, and the matte structure is formed in one-piece with the main body.

  • Publication number: 20180338746
    Abstract: The disclosure is directed to a power management method and an ultrasound apparatus using the same. The ultrasound apparatus includes an ultrasound probe, an TRX circuit, a position sensor, and a processor. In the disclosure, power is supplied to the ultrasound apparatus, and an ultrasound scanning is performed. During the ultrasound scanning, position information of the ultrasound probe is being continuously detected by the position sensor. Whether the ultrasound probe is in a static state during the ultrasound scanning is determined. When determined that the ultrasound probe is in the static state during the ultrasound scanning, a power saving mode is entered, such that the ultrasound scanning is stopped. Within the power saving mode, the position information is continuously detected. Whether the ultrasound probe is still in the static state under the power saving mode is determined.

  • Patent number: 9908844
    Abstract: Epoxy/MMT composite material and a crosslinking method for epoxy/MMT composite material with second order nonlinear optical properties are introduced. Chromophore-containing intercalating agents are applied to modify montmorillonites (MMTs) to form organoclays by an ion-exchange process, wherein the chrmophores are neatly packed on exfoliated epoxy/organoclay nanocomposites. As a result, optical nonlinearity, i.e. the Pockels effect is observed for the nanocomposites without resorting to the poling process due to self-assembly process. Furthermore, a series of epoxy/MMT nanocomposites comprising thermally reversible furan-norbornene Diels-Alder adducts are prepared to establish a crosslinking feature. Self-alignment behavior, electro-optical (EO) coefficient and temporal stability of the epoxy/MMT nanocomposites are improved by the Diels-Alders crosslinking.
