  • Publication number: 20230019995
    Abstract: A method may involve applying, by a testing computing device, a distortion to a computing device under test. The distortion includes operating the computing device under test at a performance range of a computational resource that could cause the computing device under test to operate outside a normal range. The method may also involve receiving, by the testing computing device and in response to the applying of the distortion, one or more digital signals from the computing device under test. The method may further involve comparing, by the testing computing device, the one or more digital signals to one or more baseline digital signals associated with the computing device under test. The method may also involve detecting, based on the comparing, a presence of at least one anomalous element that could be indicative of a hostile element in the computing device under test.

  • Patent number: 10178290
    Abstract: The present invention relates to a method and apparatus for long-range facial and ocular acquisition. One embodiment of a system for acquiring an image of a subject's facial feature(s) includes a steerable telescope configured to acquire the image of the facial feature(s), a first computational imaging element configured to minimize the effect of defocus in the image of the facial feature(s), and a second computational imaging element configured to minimize the effects of motion blur. In one embodiment, the detecting, the acquiring, the minimizing the effect of the motion, and the minimizing the effect of the defocus are performed automatically without a human input.

  • Publication number: 20170098117
    Abstract: The present invention relates to a method and apparatus for standoff facial and ocular acquisition. Embodiments of the invention address the problems of atmospheric turbulence, defocus, and field of view in a way that minimizes the need for additional hardware. One embodiment of a system for acquiring an image of a facial feature of a subject includes a single wide field of view sensor configured to acquire a plurality of images over a large depth of field containing the subject and a post processor coupled to the single sensor and configured to synthesize the image of the facial feature from the plurality of images.

  • Patent number: 7540776
    Abstract: A heat-shrink tube for an electrical power cable comprises a sleeve having an insulating inner layer, a conductive outer layer and a thermoplastic mid-layer located between the inner and outer layers. The mid-layer is recovered by the application of heat thereto. The insulating inner layer is preferably comprised of an elastomeric material and the thermoplastic mid-layer is rigid and acts to retain the inner layer in a radially expanded state prior to its recovery.

  • Publication number: 20040253433
    Abstract: A sheet-like electrical stress control article includes at least one void-filling layer of elastomeric void-filling material having some electrical stress control functionality (for example, containing 20 to 70% by weight of electrically conductive or semi-conductive fillers) and at least one support layer of elastomeric material selected and/or formulated (for example, with 45 to 65% by weight fillers) to require increasing applied stress to produce therein a given unit of strain as it approaches its break point The thickness and composition of the respective layers are selected so that the article is stretchable during application thereof to parts of a cable and the increasing stress required to stretch the support layer resists over-elongation of the void-filling layer.

  • Patent number: 6363856
    Abstract: A projectile for small arms, incorporating a core, skirt, and driving band. The present invention's design acts to increase muzzle velocity in three main ways. The core is lightweight, therefore, the same amount of propellent will cause the present invention to be pushed out of the barrel at a higher rate than a conventional heavier bullet. Additionally, a thin skirt circumscribing the base of the projectile is incorporated into it during manufacture. All of the design characteristics of the present invention act to increase the muzzle velocity of the projectile when used with a conventional load as compared to the same load used with a conventional projectile. The increased velocity is achieved in standard small arms without modification to barrels, recoil springs, or other devices. Law enforcement officers must be extremely careful in regard to innocent bystanders who may potentially be hit be an errant bullet, or by a bullet that over-penetrates its target.
