Abstract: Nuclear quadrupole resonance measurement using two or more wire loop(s) within a space to define a portal, and driving the wire loop(s) with a baseband digital transmitter generating a chirped or stepped signal, to create a corresponding varying electromagnetic field within the portal. Coherent emissions reflected thereby are detected through a directional coupler feeding the transceiver. The detected coherent emissions are processed with a matched filter to determine presence of a target object within the portal.

Abstract: System and methods for detecting substances such as explosives via the nuclear quadrapole resonance effect. We observe that the nuclear quadrupole resonances of explosives located within a cavity portal involve continuous Rabi transitions which are nonlinear processes since stimulated emission occurs. In other words, where there are no resonances caused by the presence of an explosive, high average power and low average power measurements should be identical. However, when resonances are stimulated by the system, the difference between these two conditions can be compared to determine a correction to measurements made when a person located in the cavity has explosive material on their person, without the need for separate empty portal or elaborate calibration procedures.

Abstract: A vertical seat motion lock apparatus is provided and includes a seat base, a locking system coupled to the seat base and disposable in a locking position, at which the locking system is configured to permit upward seat base movement and to prevent uncommanded downward seat base movement, and an unlocked position and a control system coupled to the locking system, the control system being biased to cause the locking system to assume the locking position and configured to be selectively actuated to cause the locking system to assume the unlocked position.

Abstract: For use with a front-end loader etc, the coupler-assembly provides a rigid connection between the pivoting arm-end and the bucket. Included is a slider-block, guided in slide-guides and slider-slots in side-plates of the frame of the arm-end. Sliding the block using a hydraulic slider ram, wedges the bucket lugs tightly into the frame. The slider-ram is integrated into and moves with the block. A lock-spring urges a lock-bolt into position to lock the bucket-lug to the arm-end frame. A lock-ram releases the lock-bolt, to permit dis-engagement.

Abstract: A touch screen, now incorporated in most smart phones, presents an effective and transparent method to incorporate continuous active user verification schemes. The projected capacitive grid structure can be used to capture enough information to verify that a valid user currently has possession of the mobile device, even while the user is not consciously engaged in an active verification interface. Further processing, such as habitual gesture recognition, can augment the process.

The method includes receiving, by the amusement device, an input of currency from the user. A game of chance sequence for determining the bonus is automatically initiated in response to receiving the input of currency. The game of chance sequence and the determined bonus are displayed and the bonus is applied to the play session.

Abstract: A system for configuring a venue environment based on venue-specific observations is described. A controller receives inputs associated with one or more patrons of the venue. The inputs are analyzed to determine one or more environmental preferences associated with the patrons. At least one environment modification is identified based on the one or more environmental preferences. The venue environment is modified based on the identified modifications.

Abstract: A venue-specific entertainment system is described. A communications controller is configured to communicate with electronic devices deployed at a venue, including at least two different types of electronic devices. The electronic devices are configured to communicate with one another by transmitting messages through the communications controller. The communications controller detects events based upon information from the electronic devices and transmits messages to other electronic devices to modify their output based upon the detected events.

Abstract: A system for disseminating venue-specific content output information to users is described. A venue database stores a plurality of venue entries associated with a respective plurality of venues. Each venue entry includes information identifying one or more content output devices deployed thereat. A controller is communicatively coupled to the content output devices by a first network. The controller is configured to receive, over the first network, from the content output devices, identifying information associated with the content being output by the respective content output devices deployed at the plurality of venues. The controller also updates the venue entries stored in the venue database with the received identifying information of content being output by the content output devices deployed at the respective venues. A server is accessible by computing devices of users over a second network to retrieve the identification information stored in the venue database.

Abstract: Dispersive properties of a linear dispersive delay line are retained in a spiral configuration by constraining the radius of curvature depending on a desired propagation mode. The compact form factor spiral can be either a continuous spiral or a piecewise linear approximation. The spiral comprises a highly dielectric waveguide such as titanium dioxide or barium tetratitanate. Preferably, a spacer with a low dielectric constant and a microstrip are disposed on the top surface. The microstrip prevents attenuation of low frequencies, thereby increasing the operating frequency range. A second dielectric spacer and a second microstrip can be deposited on the bottom surface of the waveguide. Alternatively, the bottom surface of the waveguide can face a ground plane. The waveguide can be fed by horns or half-horns.

Abstract: A method of converting audio selections to video selections is described. An input of an audio selection is received from a user. A database of music videos is queried to determine whether a music video corresponding to the audio selection is available. The audio selection is output in response to determining that the database of music videos does not include the music video corresponding to the audio selection. An offer is presented to the user to upgrade the audio selection to the music video corresponding to the audio selection in response to determining that the database of music videos includes the music video corresponding to the audio selection. The music video is output to one or more displays in response to the user accepting the presented offer.

Abstract: A system that uses the nuclear quadrupole resonant effect to detect the presence of materials of interest, such as may be excited by radio frequency fields generated within a portal. Transmitted chirp signals may be processed using matching filtering and other signal processing to accurately detect the presence of such materials.

Abstract: A yarn object which, even though made of ultra-high-molecular-weight polyethylene, can be satisfactorily prevented from color fading caused by contact with other objects or the like, can be produced easily at low cast, and can maintain high strength. The yarn object is colored with a colorant. The yarn object includes a core yarn 2 colored with a predetermined colorant and an outer-layer yarn 3 disposed on the periphery of the core yarn. The outer-layer yarn 3 is disposed in such a manner that the core yarn 2 is prevented from contacting with other objects. The outer-layer yarn 3 includes a transparent filament and a space 4 is formed between the outer-layer yarns 3. The color applied to the core yarn 2 is externally visible through the transparent outer-layer yarn 3 and the space therebetween 4.

Abstract: A self-stowing jumpseat consists of a seat frame that is deployed by pulling the seat frame out of a pocket formed in the edge of a bulkhead. Once the seat frame has been deployed and locked in position, the seat pan is folded down to enable a user to be seated. The seat pan is spring-loaded to fold up, so that when the user vacates the seat, the seat pan automatically folds up into the closed configuration. As it does so, an interlock lever attached to the seat pan trips the seat frame locks from their locked to their unlocked positions. The seat frame has a retraction mechanism that urges the seat into the pocket. Accordingly, as soon as the seat pan interlock lever releases the seat frame locks, the retraction mechanism causes the folded seat frame to move into the stowed position within the bulkhead.

Abstract: An electromagnetic energy concentrator uses a prism and waveguide with a gap layer of uniform thickness disposed between the prism and a first surface of waveguide. Energy detectors, which may be photovoltaics or miniaturized antenna elements are disposed adjacent to and co-extensive with a second surface of the waveguide. The detectors operate in each of at least two bands; a distance between detectors operating in a given band depends on a wavelength in the given band.
