  • Publication number: 20240158632
    Abstract: A resin composition is provided, which includes a novel low dielectric resin, a SBS resin, a cross-linking agent, a PPE resin, a halogen-free flame retardant, a spherical silica, and a siloxane coupling agent. The novel low dielectric resin is a maleimide resin. With the formula, the resin composition may improve resin fluidity and glass transition temperature (Tg) while maintaining low dielectric, thereby enhancing the overall processability.

  • Publication number: 20240162108
    Abstract: A knockdown heat sink structure includes a carrier body with a high-temperature section in contact with at least one heat source. A non-high-temperature section of the carrier body has a first radiating fin assembly, while a higher second radiating fin assembly is on the high-temperature section. The second radiating fin assembly has a first part higher than the height of the first radiating fin assembly, and a second part that outward spreads and extends from a top end of the first part and covers the first assembly without touching it, creating a spacing flow way. Therefore, the structure increases the heat dissipation area for the high-temperature section, allowing for faster heat dissipation.

  • Patent number: 11983522
    Abstract: A computing device receives one or more idle state conditions that indicate an idle device state for a class of devices associated with the computing device. The computing device receives an over the air (OTA) update of a firmware of the computing device, where the OTA update is to be applied by the computing device responsive to detecting the idle device state of the computing device. The computing device identifies a device state of the computing device and determines whether the device state satisfies the one or more idle state conditions. Responsive to determining that the first device state of the computing device satisfies the one or more idle state conditions, the computing device applies the OTA update of the firmware to the computing device.

  • Publication number: 20240152032
    Abstract: A dynamic aperture module includes a blade set and a driving portion. The blade set includes a plurality of blades, which are disposed around an optical axis to form a light through hole and rotatable for adjusting the light through hole. The driving portion includes a rotating element, at least one magnet and at least one coil. The rotating element corresponds to the blades and is configured to drive the blades to rotate, so that a dimension of the light through hole is variable. The magnet includes four polarities. The polarities of the magnet are relatively distributed along a direction surrounding the optical axis and a direction parallel to the optical axis, respectively. The coil corresponds to the magnet, and one of the magnet and the coil is disposed on the rotating element. The magnet and the coil are disposed along the direction parallel to the optical axis.
