Abstract: In a security check, a complete cart with pieces of luggage is scanned to determine whether a threat is present or not. An image is provided, of the cart and owner, before delivery of the cart to the scanner, and if a threat, usually one or more predetermined substances or items, is present, the image is provided to allow identification of the owner. Also, the image may be used for determining whether pieces of luggage are lost in the scanner.

Abstract: An antenna includes a slot feed on the radiator itself (On Radiator Slot Fed Antenna or ORSFA) instead of the slot feed being a separate element. One of the advantages of having the slot feed integrated onto the radiator is that the antenna is less dependent on the adjacent conductive parts, since the feed is coupling to the radiator rather than to ground (as is done in a standard slot feed antenna concept). The Q of the radiator can also be reduced for a given volume, since the coupler is removed from the antenna volume. In an embodiment the antenna can include a transmission line and an impedance match circuit directly on the radiator.

Abstract: A dipole antenna system is disclosed. An indirect feed technique is used to feed the antenna and the radiating elements are connected to a shield of a coax cable. The balanced termination allows for improved bandwidth compared to conventional dipole antenna configuration and helps manage current on the shield of the coax cable.

Abstract: The invention relates to a flow adjustment valve (1) comprising a valve housing (2) having a flow channel (3) and a pipe stub (10), disposed at an angle to the flow channel (3). A throttle unit (6) is arranged in the flow channel (3) and comprises a throttle element (8) that can be actuated through the pipe stub (10). The flow adjustment valve also comprises two measuring points (14, 15) for detecting the pressure in the flow channel (3) at both sides of a throttle arrangement, each of which measuring points being connected to a pressure measuring connection (17) via a pressure measuring channel (26, 27). The aim of the invention is to improve the design options for a flow adjustment valve of the aforementioned type. For this purpose, at least one pressure measuring channel (26) is guided through the pipe stub (10).

Abstract: An antenna is disclosed where a third resonator is added to the resonating structure. Impedance bandwidth improvements can be obtained for both high and low bands, with only a small increase of the antenna volume. The low band bandwidth can be further enhanced by active switching of the low band feed.

Abstract: The invention relates to a flow adjustment valve (1) comprising a valve housing (2) having a flow channel (3) in which a throttle unit (4, 11) having an adjustable throttle element (11) and a shut-off unit having a shut-off element (4) which blocks the flow channel (3) in a closed position are arranged, the shut-off element (4) being actuatable from the outside by means of a handle (16). The aim of the invention is to simplify the handling of a flow adjustment valve of the aforementioned type. For this purpose, the throttle element (11) can also be actuated by means of the handle (16).
