  • Publication number: 20240088307
    Abstract: A semiconductor package is provided. The semiconductor package includes a heat dissipation substrate including a first conductive through-via embedded therein; a sensor die disposed on the heat dissipation substrate; an insulating encapsulant laterally encapsulating the sensor die; a second conductive through-via penetrating through the insulating encapsulant; and a first redistribution structure and a second redistribution structure disposed on opposite sides of the heat dissipation substrate. The second conductive through-via is in contact with the first conductive through-via. The sensor die is located between the second redistribution structure and the heat dissipation substrate. The second redistribution structure has a window allowing a sensing region of the sensor die receiving light. The first redistribution structure is electrically connected to the sensor die through the first conductive through-via, the second conductive through-via and the second redistribution structure.

  • Patent number: 11616627
    Abstract: A communication system, a data transmission method thereof, and a user device thereof are provided. The data transmission method includes the following steps. A first transmitting Radio Link Control (Tx RLC) entity of a first base station transmits a first Protocol Data Unit (PDU) to a first receiving Radio Link Control (Rx RLC) entity of a user equipment via a first leg. A second Tx RLC entity of a second base station transmits a second PDU to a second Rx RLC entity of the user equipment via a second leg. If the first Rx RLC entity successfully receives the first PDU or the second Rx RLC entity successfully receives the second PDU, the first Rx RLC entity and the second RLC entity return Acknowledgement (ACK) messages.

  • Patent number: 7159283
    Abstract: A locking device for a panel is provided for a single board computer for fixing onto the chassis of an industrial personal computer. The locking device includes a handle, a locking element, a first spring, a seat and a second spring. The handle has a concave groove at the front-end thereof for receiving the locking element. The first spring is placed in an inner of the locking element for abutting against an inner portion of the handle. The pin penetrates through the seat and the handle and fixes them together. The second spring is mounted on the pin and has an end hooked to the locking element. The locking element has a pressing portion. When the pressing portion is pressed, the handle and the locking element move back together through the pin as an axis.
