  • Patent number: 6751006
    Abstract: Addressed herein are techniques and equipment for pre-processing digital images to be superimposed for display. Filtering, re-sampling, and decimation are variously used to process images and sub-images to produce to-be-superimposed images. One of the described techniques is designed primarily (although not necessarily exclusively) for computational efficiency, while the other sacrifices some computational efficiency for higher quality of output images.

  • Patent number: 6746356
    Abstract: A gear assembly (10) for transmitting torque between an input rotatable member (12) and an output rotatable member e.g. differential unit (24) comprises an input gear (14) rotatable with the input member (12), an output gear (20) rotatable with the output member (24), and intermediate gears (16a, 16b, 16c, 16d) held simultaneously in mesh with the input gear (14) and output gear (20). Various arrangements are disclosed for sharing the transmitted torque evenly between the paths provided by gears (16a, 16b, 16c, 16d). The transmission may provide a reduction ratio and is connected to a low reduction ratio differential gearbox of small size and slim profile.

  • Patent number: 6742840
    Abstract: Adjustable seats and components thereof are detailed. The seats, particularly (although not exclusively) useful in commercial aircraft, permit substantial angular recline without the corresponding rearward linear movement necessarily occurring in conventional seats. The seats additionally may have discontinuous, or non-integral, seat bottoms, with the heights of the forward portions of the bottoms being adjustable mechanically. Tray tables optionally associated with the seats further omit any central slot and may define one or more pivot axes in locations different than exist in conventional seats.

  • Patent number: 6723420
    Abstract: This invention relates to the nature of thick film compositions that are specifically designed for the fabrication of circuit elements on diamond substrates, especially resistive elements. The nature of diamond sheet material requires special consideration because of its relatively low coefficient of thermal expansion and its sensitivity to oxygen at elevated processing temperatures. The general compositional requirements of thick film paste formulations are provided as a basis for accommodating the particular physical properties of diamond, and thereby establishing a method by which high performance microelectronic components can be fabricated economically. Thick film pastes containing certain borosilicate glasses, metal components, and optionally semiconducting materials are demonstrated to possess favorable behavior in terms of mechanical and electrical properties after sintering. Resistive elements on diamond can be fabricated by adding conductive components to a borosilicate glass.

  • Patent number: 6699571
    Abstract: Devices and methods for mounting components of electronic circuitry and these mounting devices are capable of surviving repeated thermal cycling. The devices comprise two metal laminate members brazed to a ceramic member on each of the two major surfaces of the ceramic member. The laminates preferably comprise a layer of molybdenum disposed between two layers of copper. The thickness of the individual layers comprising the metal laminate member may be varied to yield a laminate CTE similar to the CTE of the ceramic member to be joined.

  • Patent number: 6679448
    Abstract: A handset cable reel for use e.g. in passenger aircraft comprises a spool fitted with a rewind bias spring, the spool also having peripheral teeth 82. These interact with an oscillating pawl 62, a ratchet/star wheel 60 and a pawl 57 so that, after the cable has been extended a certain amount, repeatedly releasing and then pulling on the cable will alternately lock the spool to prevent retraction of the cable by the rewind bias, and then allow such retraction under the influence of the rewind spring. A driving key 100 on the spool indexes a cam wheel 88 for rotation so that as the final length of the cable is being rewound, a cam surface 96 rotates the pawl 57 about a pin 48 so that it no longer co-operates with the star/ratchet wheel 60 and the cable remains under spring tension even if inadvertently tugged.

  • Patent number: 6680026
    Abstract: “Plug-in” fluid flow diverters are disclosed. Additionally disclosed is water purification equipment adapted to communicate with the diverters. Such equipment is especially (although not solely) useful in connection with circulating streams of water present in systems associated with swimming pools, hot tubs, and spas, as the circulating nature of the water permits more of its volume ultimately to be diverted into the equipment for purification. The diverters, furthermore, may have entrances oriented to receive fluid travelling in only one direction through a conduit and be keyed to one or more components of the equipment for purposes of identification, inventory control, or otherwise.

  • Patent number: 6666124
    Abstract: Armored protective panels for inflatable (and other) boats are detailed. The panels themselves may be inflated, either separately or together, for deployment and hence need not normally impede navigation or performance of the boats. If relatively flexible anti-ballistic materials are selected as components, the panels may be designed to collapse into rolls when not inflated. Alternative panels may include stealth or other non-anti-ballistic materials or be designed for use with objects or vehicles other than boats.

  • Patent number: 6666143
    Abstract: Many of today's weapons systems use surveillance and target acquisition (STA) devices which can exploit the infrared and millimeter wavebands of the electromagnetic spectrum. Designing obscurant devices which can provide screening against such systems often results in complicated or costly solutions. A device capable of mitigating these problems is described wherein an obscurant device (10), and more particularly a device capable of providing screening against the visual, infrared and millimeter wave regions of the electromagnetic spectrum, comprises an obscurant payload, a burster charge capable, when detonated by a detonator, of disseminating said payload and a payload casing wherein some or all of the payload casing is configured to disintegrate upon actuation of the burster charge and to act thereafter as an obscurant.
