It provides a raw interface to data link layers, permitting raw link-layer packets to be sent and received. In addition, if the driver for the network interface supports promiscuous mode, it allows the interface to be put into that mode so that all packets on the network can be received, even those destined to other hosts. potters ace hardware livingston

WebMay 8, 2024 · EDOF imaging with Leica widefield optics (stereo, compound, or digital microscopes) is based on focus variation. The limited focus depth (depth of field) of the optics is exploited to determine sample height and depth information. WebThe EDOF IOL, or extended range of vision IOL, is a new technology in the treatment of presbyopia-correcting lenses. The basic optical principle is to create a single-elongated focal point to enhance the depth-of-focus, on the contrary to monofocal IOLs (in which light is focused on one single point) or MF IOLs (having 2 or 3 discrete points).

WebeBPF is an extended version of the Berkeley Packet Filter (BPF).
