H01Q 13/10

US Classification:

343771, 343767, 427 58, 427123

Abstract:

A dual-polarized antenna array is disclosed. The antenna array includes a plurality of self supporting, electrically conductive members. Tapered elements of neighboring electrically conductive members define tapered slots that form part of radiating structures. The radiating structures additionally include a slot line in communication with the tapered slot. A back cavity can be included as part of a BALUN structure that is integral to an electrically conductive member.

Assignee:

Hewlett Packard Company - Palo Alto CA

International Classification:

G01D 1124
G01N 2300
F16M 1300

US Classification:

73431

Abstract:

The inventive mechanism has an RF door separate from the drawer of an automatic testing machine fixture. The door is either attached to an adapter which holds a device that is to be tested, or attached to a peripheral portion of the fixture. Consequently, changing the adapter is simplified, and the likelihood of damage to the adapter is lowered. When the drawer is in a closed position, the door meshes with the fixture to provide an RF sealed area for RF testing a device.

International Classification:

A47J 3700

US Classification:

Abstract:

A belt grill is described herein for continuously cooking fast food products on a conveyor formed of counter-rotating heat conductive belts. The belts are heated by platens disposed above and below whereby a run of the belts passes in heat conductive relationship between the platens, and the food to be cooked is placed in the nip between the rotating belts. The device further includes means for tensioning the belts which can be automatically released by increasing the distance between the platens whereby when the distance exceeds a predetermined maximum, all tension on both belts will be released so that the belts can be quickly removed for cleaning or replacement. The belts are preferably Teflon coated fiberglass and may be disposed at an angle to the horizontal to facilitate grease removal from the cooking process.

International Classification:

H04B 1700

US Classification:

738659

Abstract:

The inventive fixture adapter has installed pneumatic actuators. Pneumatic connections for the actuators are made during installation of the adapter in the fixture. Thus, testing of a device can begin before the drawer is closed, and be completed while the drawer is being opened, thus saving cycle time. The adapter is removably connected to the drawer mechanism of the fixture, and thus can quickly and reliably be changed for a different adapter. All of the customization required for a particular device can be confined to the adapter, and thus the reset of the fixture can be made generic.
