Patent number: 10461438Abstract: Systems, methods, and devices relating to an antenna element and to an antenna array. A three level antenna element provides wideband coverage as well as dual polarization. Each of the three levels is a substrate with a conductive patch with the bottom level being spaced apart from the ground plane. Each of the three levels is spaced apart from the other levels with the spacings being non-uniform. The antenna element may be slot coupled by way of a cross slot in the ground plane. The antenna element, when used in an antenna array, may be surrounded by a metallic fence to heighten isolation from other antenna elements.Type: GrantFiled: February 28, 2017Date of Patent: October 29, 2019Assignee: Communication Components Antenna Inc.Inventors: Lin-Ping Shen, Hua Wang, Willi Manfred Lotz, Minya M.

Patent number: 8320121Abstract: A computer system may include a chassis defining a front and a rear. The chassis may include a vertically oriented midplane disposed therein, the midplane including a plurality of front module slots for receiving front electronic modules from the front of the chassis, and a plurality of rear module slots for receiving rear electronic modules from the rear of the chassis. A cooling system may be provided within the chassis and may generate an upwardly-directed front air flow within the chassis directed at selected ones of the front electronic modules and an upwardly-directed rear air flow within the chassis directed at selected ones of the rear electronic modules. The front air flow is separate from and independent of the rear air flow. The selected front and rear electronic modules may be disposed in the chassis so as to separate the front air flow into a plurality of substantially equal front air streams and the rear air flow into a plurality of substantially equal rear air streams, respectively.Type: GrantFiled: October 11, 2010Date of Patent: November 27, 2012Assignee: Liquid Computing CorporationInventors: Sylvio Bisson, Willi Manfred Lotz

Patent number: 6683252Abstract: A latching device is provided for a circuit pack having a cable retainer carried upon the front of the operating lever of the device. The cable retainer is oriented for positional and directional control of cable by directing cable longitudinally of the faceplate of the circuit pack and away from the fronts of other circuit packs within a shelf. Also provided is a combination of a latching device and two groups of covers. The combination enables a single latching device to be used upon circuit packs requiring security and non security conditions within a shelf. It also enables removal of a faceplate held to a faceplate mounting with the circuit pack in the shelf. An orifice in an operating lever of the device is accessible with a cover of the first group mounted upon the operating lever, as orifices in these covers align themselves with the orifice in the operating lever.Type: GrantFiled: July 31, 2001Date of Patent: January 27, 2004Assignee: Alcatel Canada Inc.Inventors: Jay Richard Sobel, Raymond Woo, Bevin Grant Schmidt, Willi Manfred Lotz
