Abstract: A radio frequency identification (RFID) tag reading system having a phased antenna array accurately locates RFID tags in a controlled area, by steering an interrogating beam over the controlled area to interrogate the tags and generate return modulated RF signals. A primary receiver steers a primary receive beam at a primary steering angle that is fixed during each tag interrogation. A primary demodulator demodulates and reconstructs the received return modulated signals. A secondary receiver, independently of the primary receiver, steers a secondary receive beam at a plurality of secondary steering angles. A secondary correlator/demodulator demodulates the combined return modulated signals, and utilizes the reconstructed signal reconstructed by the primary demodulator at each of the secondary steering angles. Both the primary and the secondary receivers cooperate to accurately locate the same tag.

Preferably, the non-rotationally symmetrical optics includes a cylindrical lens having an aspherical profile along the one direction, and a planar profile along the other of the directions.

Abstract: An imaging lens assembly captures return light through a window of a vertical slot scanner from a target located in a range of working distances along an optical axis away from the window, and projects the captured return light onto an array of a solid-state imager. The imaging lens assembly is optically modified for non-uniform magnification within, and for increasing resolution at an outer peripheral region of, a field of view of the array, in an imaging plane generally perpendicular to the optical axis. The magnification is at least partly increased in the imaging plane with increasing radial distance away from the optical axis, to enable reading of the target when tilted relative to the optical axis and located at the outer peripheral region of the field of view.

Abstract: The present disclosure provides systems and methods for detecting attacks against authentication mechanisms that generate Transport Layer Security (TLS) tunnels using a server public key. Such attacks can include misconfigured wireless local area network (WLAN) clients that fail to authenticate the server public key prior to creating the TLS tunnels and exchanging credentials. In an exemplary embodiment, an intrusion detection system (IDS) or intrusion prevention system (IPS) is aware of the server public key and monitors for authentication handshakes to detect invalid keys.
