There is provided a system and method for human verification by a contextually iconic visual public Turing test. There is provided a method comprising receiving a request to verify whether a client is human controlled, selecting, by contextual criteria, a plurality of images each having one or more associated tags from a database, generating a challenge question and a corresponding answer set based on associated tags of a subset of the plurality of images, presenting the plurality of images and the challenge question to the client, receiving a submission to the challenge question from the client, and responding to the request by verifying whether the submission is contained in the answer set to determine whether the client is human controlled. The contextual criteria may comprise subject matter, branding, or intended audience of a content provider sending the request, thereby facilitating human responses while deterring automated systems.

A dispensing apparatus for dispensing a lid from a stack of lids each having a lid periphery includes a load platform having a main floor on which to place a stack of lids, the main floor sloping downward from an apex in a rearward direction, the load platform having a forward slope inclined downward from the apex in a forward direction. A parallelogram mechanism is mounted to move in a linear direction forward to a dispense position and rearward to a home position. A hinge is coupled to the parallelogram mechanism and has a handle with a distal end oriented upward and forward to contact an inner surface of a lid periphery of a bottommost lid of the stack of lids when the parallelogram mechanism moves forward from the home position toward the dispense position. After the distal end of the handle of the hinge contacts the inner surface of the lid periphery of the bottommost lid, the parallelogram mechanism deforms to de-elevate the hinge and move the distal end of the handle of the hinge downward causing the bottommost lid to deformably move downward to the forward slope of the load platform to separate from the stack of lids for dispensing.

Complementary metal oxide semiconductor transistors are formed on a silicon substrate. The substrate has a {100} crystallographic orientation. The transistors are formed on the substrate so that current flows in the channels of the transistors are parallel to the direction. Additionally, longitudinal tensile stress is applied to the channels.

摘要:
A method to present easily understood images that represent targets that are detected through walls or other opaque barriers is disclosed. This method is particularly well suited for sense-through-the-wall radar systems. One of the main challenges of evolving STTW systems is that the practitioners of the technology are generally presented with complicated images to represent the gain adjusted amplitude of signals that are detected by the radar. Interpretation of images from prior art, which can be in the form of the radar speckle, target blob, wiggle plot, and horizontal amplitude intensity displays, shown in FIGS. 1 through 3, requires high levels of skill, focus, and time. Naturally, the foregoing places military and law-enforcement customers of the technology at considerable risk during hostile missions. This invention discloses a method that converts a typical radar signal into an image that is easily understood by a practitioner of STTW technology. This invention improves prior art by employing any combination of radar data interpretation with any combination of video feed overlay, hologram, target silhouettes, lines, borders, colored target representations and the like to concisely report target information to a STTW device operator.

A low-cost high performance ultra wideband antenna that can be machine replicated is disclosed. The apparatus includes an inner closed-loop broadband antenna circuit that may be comprised of single or multiple conductive sheets that are electrically connected by conductive or impedance tapered regions that are positioned in an area that does not interfere or interferes minimally with antenna performance. Two continuous sheets of dielectric material cover the back reflector shield area, which leaves only the antenna elements exposed. The dielectric materials are subsequently enclosed by inner and outer conductive shields that are electrically connected to common ground and side shields that may be used to improve directivity. The closed-loop broadband antenna circuit and the feed-point connections may be grounded by a separate path within the device. The resulting stack of materials is easily machine assembled into an antenna apparatus by employing stamping, folding, injection, or other methods.

An economically attractive method to provide multiuse broadband connectivity to the edge of legacy telecommunication and emerging networks is disclosed. The invention utilizes a multi-phase common signal return coupling scheme that passes signals onto the step-down side of power transformers. This invention enables the transformer to serve as an economically attractive distribution point that transfers external payload signals from service providers to customer network access points on the load side of the transformer. The resulting power line network will permit remote control of utilization and access to any legacy or emerging network payload such as ITU and IETF that is present at any type of electric power transformer.

A novel approach is disclosed that mitigates flare-end ringing induced distortion of impulse signals that are transmitted from an electromagnetic radiator. Conventional tapering suppresses energy in the return path by impedance loading the antenna element at the expense of reduced radiation efficiency. This disclosure presents a method that balances the trade-off between radiation efficiency and return path energy suppression while it simultaneously minimizes taper induced signal distortion effects on the front edge of the transmitted impulse. The balance between radiation efficiency, end-fire ringing, and impulse distortion is achieved by placing impedance loading at only at or near the second half of the antenna element. Recent disclosures show the advantage of determining the position of each band through mathematical calculation and by subsequently removing select bands near the feed point to move the reflected pulse away from the front-edge of the transmitted impulse. This disclosure will show that optimal placement of the first tapered band is substantially more critical. The reflection caused by this interface must reach the original impulse at a position that will minimally interfere with its front edge.
