Abstract:
An electromagnetic (EM) field mitigation system includes a ground plane (510), an antenna element (502), and a parasitic resonator element (504). The antenna element is coupled to the ground plane and resonates within at least one predetermined frequency band for transmitting and receiving radio frequency (RF) signals modulated at one or more frequencies within at least a first frequency band. The parasitic resonator element includes at least a first leg (506) and a second leg (508) connected to the ground plane and located a predetermined distance (514) from the antenna element for mitigating the EM emissions of the antenna element at one or more predetermined locations within a HAC measurement plane. The first leg of the parasitic resonator element is connected to the ground plane on a first side of an effective electric field mid-line (512) laterally dividing the ground plane, and the second leg of the parasitic antenna element is connected to the ground plane on a second side of the effective electric field mid-line.
Abstract:
A retracting lifeline system, includes: a housing, a first connector attached to the housing, a lifeline, and a hub to which the lifeline is attached at a first end of the lifeline and around which the lifeline is coiled within the housing. The housing includes an opening through which the lifeline exits the housing. The hub is tensioned to rotate in a first direction to cause retracting of the lifeline and coiling of the lifeline around the hub. The retracting lifeline system further includes a second connector attached to a second end of the lifeline. At least a section of the lifeline has an initial ultimate tensile load of at least 8000 pounds and is abrasion resistant (that is, satisfying the abrasion test requirement set forth in the ANSI/ASSE Z359.13-2009 standard) such that the section of the lifeline is available for tie- back anchoring using the second connector. The section of the lifeline is at least partially retractable within the housing.

Abstract:
A button attaching device (11) includes a top member (31) and a bottom member (17) which are hingedly connected together, the bottom member (17) including an anvil (27). The button attaching device (11) further includes a needle block assembly (15) mounted on the top member (31). The needle block assembly (15) includes a block of material (47), a pair of rodless fastener dispensing needles (55, 57) and a fastener (59, 61). In one embodiment of the present invention, the needle block assembly (15) is removably mounted on the top member (31) and is sized and shaped so as to fit within a needle block assembly storage compartment (29) formed in the bottom member (17). In another embodiment of the present invention, a plurality of needle block assemblies (129) are interconnected to form a needle carousel (105) which is rotatably mounted within a hollowed portion (125) formed in the top member (109).
Abstract:
A button attaching device for attaching a button having four holes to a layer of material includes a holder having a front end and a rear end, four rodless fastener dispensing needles (27) projecting out from the front end of the holder and two fasteners (35, 77), each having a foot at each end of an elongated filament. Each foot is removably mounted on one of the rodless fastener dispensing needles. A cover (17) is removably mounted on the front end of the holder and includes an anvil (55). In use, the cover is removed from the holder and the layer of material placed on the cover over the anvil. The button is then placed over the layer of material. The holder is then pushed in the direction of the cover so that the needles and fastener feet extend through the holes in the button and through the layer of material, with the tips of the needles striking the anvil. The tension on the filaments of the fasteners causes the feet to pop out from the needles. The needles are then withdrawn leaving the button secured to the layer of material by the fasteners.
Abstract:
An electronic device (100) includes an antenna system (150) having two antennas (110, 120). A first antenna (110) has a first antenna element (111) positioned near a first corner (191) of a planar, rectangular ground plane (165) and a second antenna element (115) positioned near a second corner of the ground plane that is diagonally across from the first corner. A second antenna (120) has a third antenna element (121) positioned near a third corner (193) of the ground plane that is adjacent to the first corner and a fourth antenna element (125) positioned near a fourth corner (195) of the ground plane that is diagonally across from the third corner. At low-band frequencies, the antenna elements (111, 115) of the first antenna (110) are driven out-of-phase relative to each other. Similarly, at low-band frequencies, the antenna elements (121, 125) of the second antenna (120) are driven out-of-phase relative to each other.

Abstract:
An electromagnetic field probe is provided that is capable of measuring four electromagnetic field components in a spatial plane tangential to the central axis of the probe. The probe included two dipoles and two loops. The dipoles are disposed about the central axis at substantially 90 degree angles, while the loops are disposed from 45 to 225 and from 135 to 315 degrees, respectively. In one embodiment, a plurality of flexible conductors, signal combiners and switches are used to couple the dipoles and loops to a network or spectrum analyzer. To isolate the effects of field components that are incident to the central axis of the probe, a 180 degree signal combiner may be employed to separate the common mode signals.
Abstract:
A method of forming a printed circuit board using an ink jet print head by printing a three dimensional groove using a curable, non-conductive deposition liquid and depositing a liquid that dries to form a conductive track. The walls on either side of the groove impede the liquid from spreading and consequently larger quantities of the conductive deposition liquid can be deposited without causing a short circuit. A multi layer printed circuit board can be produced by depositing further layers of curable non-conductive deposition liquid over the conductive track, a further conductive track in an upper layer being in contact with a conductive track in a lower layer along a slope formed from the non-conductive deposition liquid.
