  • Patent number: 11967652
    Abstract: A sensor package structure includes a substrate, a sensor chip and a ring-shaped solder mask frame those are disposed on the substrate, a ring-shaped support disposed on a top side of the annular solder mask frame, and a light permeable member that is disposed on the ring-shaped support. The sensor chip is electrically coupled to the substrate. A top surface of the sensor chip has a sensing region, and the sensing region is spaced apart from an outer lateral side of the sensor chip by a distance less than 300 ?m. The ring-shaped solder mask frame surrounds and contacts the outer lateral side of the sensor chip. The light permeable member, the ring-shaped support, and the sensor chip jointly define an enclosed space.

  • Patent number: 11829544
    Abstract: An electronic device includes a cover plate assembly, a frameless display panel assembly, and an adhesive layer. The cover plate assembly has a first major surface. A peripheral region of the first major surface has a first area. The frameless display panel assembly is disposed below the cover plate assembly and has a second major surface. A peripheral region of the second major surface has a second area smaller than the first area. The adhesive layer is disposed between the peripheral region of the first major surface and the peripheral region of the second major surface. The adhesive layer is a frame-shaped and elastic colloid. The adhesive layer, the cover plate assembly, and the frameless display panel assembly together form a closed space after being pressed together, and the closed space has a spacing smaller than 200 microns.

  • Patent number: 7971043
    Abstract: An electronic system includes a pipeline having a first number of pipeline stages coupled in series, a pipeline control unit, and a logic engine, wherein each pipeline stage in the pipeline is for outputting data to a next pipeline stage at each cycle of a clock signal. The pipeline control unit is for changing the first number of pipeline stages in the pipeline to a second number of pipeline stages. The logic engine is for performing operations of the electronic system in a first mode by utilizing the pipeline having the first number of pipeline stages and for performing operations of the electronic system in a second mode by utilizing the pipeline having the second number of pipeline stages. A frequency control unit and a voltage control unit, coupled to the pipeline and the logic engine, respectively adjust the frequency and voltage of the electronic system accordingly.

  • Patent number: 7822999
    Abstract: A computer system and a method for controlling a processor thereof are provided. A processor management unit (PMU) is programmed by the processor itself or by another processor according to a change of the operating condition of the processor. Then, a notification signal is sent to the PMU by the processor when the processor is entering a standby mode. Upon receiving the notification signal, the PMU adjusts the operating condition of the processor according to the change. Finally, a completion signal is sent by the PMU to the processor after the change of the operating condition of the processor is stabilized. Therefore, the unpredictable behavior caused by premature awakening of the processor during the adjustment of the operating condition can be avoided.

  • Publication number: 20070094664
    Abstract: A first thread processor of a multi-thread processor system is operable to execute a first process, and a second thread processor of the multi-thread processor system is operable to execute a second process. A control register is operable to store priority information that is individually associated with at least one of the first thread processor and the second thread processor. The priority information identifies a prioritization of the first thread processor and/or a restriction on the second thread processor in a use of a shared hardware resource during execution of at least one of the first process and the second process.
