  • 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.

  • Publication number: 20240086633
    Abstract: A method for generating and outputting a message is implemented using an electronic device the stores a computer program product and a text database. The text database includes a main message template, a template text that includes a placeholder, and a word group that includes a plurality of preset words for replacing the placeholder. The method includes: in response to receipt of a command for execution of the computer program product, displaying an editing interface including the main message template; in response to receipt of user operation of a selection of the main message template, displaying the template text; in response to receipt of user operation of a selection of one of the preset words via the user interface, generating an edited text by replacing the placeholder with the one of the preset words in the template text; and outputting the edited text as a message.

  • Patent number: 9823123
    Abstract: A system for controlling excess bias of a single photon avalanche photo diode (SPAD) is provided. The system includes a power supply, a SPAD, a control circuit and a load. The power supply generates a supply voltage. The SPAD has a first terminal receiving the supply voltage and a second terminal generating an output voltage signal. The control circuit is connected to the second terminal of the SPAD. The load has a first terminal connected to the second terminal of the SPAD, and a second terminal connected to the control circuit for receiving a reset level. The control circuit is capable of monitoring a swing of the output voltage level and generating the reset level in response to the excess bias level and the swing of the output voltage level.
