  • Patent number: 11990493
    Abstract: An image sensor device is provided. The image sensor device includes a semiconductor substrate having a front surface, a back surface opposite to the front surface, and a light-sensing region close to the front surface. The image sensor device includes an insulating layer covering the back surface and extending into the semiconductor substrate. The protection layer has a first refractive index, and the first refractive index is less than a second refractive index of the semiconductor substrate and greater than a third refractive index of the insulating layer, and the protection layer conformally and continuously covers the back surface and extends into the semiconductor substrate. The image sensor device includes a reflective structure surrounded by insulating layer in the semiconductor substrate.

  • Patent number: 11474964
    Abstract: A configurable input/output device includes a plurality of input/output terminals, a routing module, and a first universal input/output channel. The input/output terminals are connected a plurality of field devices. The input/output terminals receive a plurality of input signals from the field devices, and output a plurality of output signals to the field devices. At least two of the input signals are different, at least two of the output signals are different, and at least two the field devices are different. The routing module is connected to the input/output terminals. The first universal input/output channel is connected to the routing module. The routing module controls connections between the first universal input/output channel and the input/output terminals. The routing module also controls the transceiving sequence for the input signals and the output signals.

  • Patent number: 10734177
    Abstract: The present disclosure illustrates an electromagnetic relay device and a control method thereof. In the electromagnetic relay device, a control circuit respectively provides driving power to switch on the two electromagnetic relay units disposed adjacent to each other, and then provides the first holding power and the second holding power, lower than the driving power, to the two electromagnetic relay units after the two electromagnetic relay units are switched on, thereby maintaining the two electromagnetic relay units in the switched-on status. When the electromagnetic relay unit receiving the second holding power is tripped because of the environmental factor, the electromagnetic relay unit receiving the second holding power generates and outputs the trip feedback signal to the control circuit, so that the control circuit increases the first holding power upon receipt of the trip feedback signal. The second holding power is lower than or equal to the first holding power.

  • Publication number: 20080104439
    Abstract: In a real time clock having a register, a preinstalled central processing unit issues a control instruction to hold a time stamp of an external register in the real time clock and then reads the time stamp of the external register, if a server or a control end needs to read the time stamp of the real time clock. The real time clock having a register is comprised of a timing generator for generating a time stamp that is stored in the external register and a controller for controlling the timing generator and the external register. The preinstalled central processing unit can read the time stamp stored in the external register, so as to accurately read the time of issuing a read command given by the central processing unit, regardless of whether or not the preinstalled central processing unit is situated in a busy state of executing other programs.
