20160065576 | SYSTEM AND METHODS FOR LEVERAGING AN OBJECT CACHE TO MONITOR NETWORK TRAFFIC - According to non-limiting embodiments disclosed herein, the functionality of an object cache in a server can be extended to monitor and track web traffic, and in particular to perform rate accounting on selected web traffic. As the server communicates with clients (e.g., receiving HTTP requests and responding to those requests), the server can use its existing object cache storage and existing object cache services to monitor web traffic by recording how often a client makes a particular request in the object cache and/or other data about the requests. Preferably, the object cache is still used for conventional caching of objects, the object cache thus providing a dual role by storing both web objects and rate accounting data. | 03-03-2016 |

20100182206 | WIRELESS NETWORK DEVICE INCLUDING A POLARIZATION AND SPATIAL DIVERSITY ANTENNA SYSTEM - A wireless access gateway for communication of wave signals at radio frequencies within a frequency band, includes an access gateway enclosed in a housing including a bottom wall and a main circuit board overlying the bottom wall and having an upper surface substantially parallel to the bottom wall. The gateway is equipped with an antenna system including at least two antennas: a first linearly polarized antenna for propagating a first wave signal along a first polarization axis including a first radiating element extending along a first longitudinal axis lying on a first plane substantially parallel to the base plane, and a second linearly polarized antenna for propagating a second wave signal along a second polarization axis oriented perpendicularly to the first polarization axis, the second antenna including a second radiating element extending along a second longitudinal axis lying on a second plane oriented perpendicularly to the first plane. The first and second antennas are positioned relative to each other at a distance of at least λ/2, where λ is the wavelength corresponding to a radio frequency within the frequency band. | 07-22-2010 |

20100066464 | DELAY ELEMENT AND A CORRESPONDING METHOD - A differential delay element for use, e.g., in selectively delaying RF signals in telecommunication systems includes a first microstrip circuit and a second microstrip circuit arranged side-by-side in a facing relationship. The first microstrip circuit defines a first delayed travel path for a first signal from a first input port to a first output port and the second microstrip circuit defines a second delayed travel path for a second signal from a second input port to a second output port. A perturber is arranged between the first and second microstrip circuits, displaceable toward and away from the first and second microstrip circuits, so that when the distance of the perturber to one of the microstrip circuits increases, the distance of the perturber to the other of the microstrip circuits decreases and viceversa. The position of the perturber between the first and second microstrip circuits defines the differential delay, namely the difference (Δτ=τ1−τ2) between the times (τ1,τ2) experienced by the two signals in travelling their travel paths through the delay device. | 03-18-2010 |
