  • Patent number: 11899172
    Abstract: An imaging optical lens assembly includes five lens elements, which are, in order from an object side to an image side along an optical path, a first lens element, a second lens element, a third lens element, a fourth lens element and a fifth lens element. Each of the five lens elements has an object-side surface towards the object side and an image-side surface towards the image side. The third lens element has positive refractive power. At least one of the object-side surface and the image-side surface of at least one of the five lens elements includes at least one critical point in an off-axis region thereof.

  • Publication number: 20080126599
    Abstract: An iSCSI target apparatus is disclosed. The iSCSI target apparatus includes a buffer device, a network interface, and a host storage hardware. The buffer device is for buffering at least a packet. The network interface is coupled to the buffer device for accessing the buffer device to transfer the packet between the network interface and the buffer device. The host storage hardware is coupled to the buffer device for accessing the buffer device to transfer the packet between the host storage hardware and the buffer device. Movement of the packet in the iSCSI target apparatus only occurs between the network interface and the buffer device and between the host storage hardware and the buffer device.
