20160049733 | Method and Apparatus for Orthogonal-Mode Junction Coupling - An orthogonal mode transducer including: an elongated waveguide conduit for projecting orthogonal polarisation transmissions, the conduit having a proximal emission source end and a distal mouth end having an aperture for signal transmission; and the elongated conduit including a first and a second pairs of diametrically opposed axial ridges, with the first and second pairs being substantially orthogonal to one another, and the first pair of diametrically opposed axial ridges having an asymmetric narrowing of the gap between the ridges towards the proximal emission source relative to the second pair of diametrically opposed axial ridges. The axial ridge increases in circumferential thickness towards the distal end of the conduit. The asymmetric narrowing is provisioned substantially at the proximal emission source end only with the gap between the first pair and the second pair of ridges being substantially the same at the distal mouth end of the conduit. | 02-18-2016 |

20110038349 | Multiple Simultaneous Wireless Connections In A Wireless Local Area Network - Multiple simultaneous associations with Wireless Access Points (WAPs) may be formed by a given wireless client to enable handoffs between the WAPs to be accelerated and, optionally, to enable both WAPs to provide simultaneous wireless services to the wireless client. Upon forming a primary association with one WAP the wireless client scans for beacon signals from other WAPs. Upon detecting another WAP, the wireless client transmits a Request To Send (RTS) message to the new WAP indicating the identity of the primary WAP. The wireless client may also identify the new WAP to the primary WAP using a RTS message. The primary and secondary WAPs exchange information so that, in the event of a handoff, the required information has already been shared with the new WAP. Optionally, the several WAPs may provide simultaneous service to the wireless client. | 02-17-2011 |
