Abstract: Systems and methods are provided for presenting media streams based on changes in geolocation. A MapView system may receive a first positioning signal indicating a first geographical location of a user device. The MapView system may determine a first media stream to be presented by the user device based on the first geographical location and a location of a source of the first media stream. The MapView system may then facilitate a presentation of the first media stream by the user device. When the MapView system receives a second positioning signal indicating a second geographical location of the user device, the MapView may identify, a second media stream to be presented by the user device based on the second geographical location being in broadcast range of the second media stream. The MapView system may then facilitate a presentation of the second media stream by the user device.

Abstract: This disclosure describes, in part, techniques for generating captions for audio content items. For instance, a system may store a user profile that is associated with audio content items. When a user associated with the user profile requests captions, the system may determine which audio content items have available captions and which audio content items do not have available captions. For the audio content items that do not have available captions, the system may determine priorities for the audio content items. The system may then cause the captions to be generated based on the priorities. When the captions are generated, the system may update statuses of the audio content items to indicate that the captions are available. The system may further store the captions in a database that is accessible to the user.

Abstract: This disclosure describes, in part, techniques for providing captions with audio content. For instance, an electronic device may receive first data representing audio content and second data representing captions that are available for the audio content. The electronic device may then select portions of the captions for display while outputting the audio content. In some instances, the electronic device selects the portions using timestamps represented by the second data. For instance, the electronic device may select a portion of the captions such that the portion of the captions begins at a first pause within the audio content and/or ends at a second pause within the audio content. In some instances, the electronic device may also display graphical elements that indicate the current location within the captions.

Abstract: A video streaming management system and method are disclosed, which includes controlled display of a first visual interface that is managed by a first video service provider (VSP) of a plurality of subscribed VSPs. The video streaming management system is associated with the plurality of subscribed VSPs and a plurality of unsubscribed VSPs. An input for a first video is received via the first visual interface. The first video, based on the received input, is searched across a plurality of video services managed by the plurality of subscribed VSPs and the plurality of unsubscribed VSPs. A video service managed by a second VSP is recommended to view the first video selected from the first visual interface, based on the search. Playback of the first video is controlled from the recommended video service managed by the second video service provider.

Abstract: A processor for filtering message traffic between communication systems may include an input buffer and an output buffer. The processor may also include a memory interface communicatively coupled to a filter rule table that includes message filter rules for verifying input messages received by the input buffer and build output message rules for constructing output messages based on the input messages received by the input buffer. The processor may additionally include a message filter state-machine circuit communicatively coupled to the input buffer that applies the message filter rules to the input message from the input buffer and determines whether the input message conforms to each of the message filter rules. The processor may further include a build output message state-machine circuit that constructs an output message based on the input message and causes the output message to be stored in the output buffer.

Abstract: Extensible media and/or activity sharing within a voice call or concurrent real-time communication session is enabled. A concurrent voice call may contextualize shared media and/or activities. Users may share live experiences within the context of a voice call. Continuous, changing real-time media types such as periodic media (e.g., a user's current location) and streaming media (e.g., what the user is currently “seeing” through their personal video camera) may be shared, as well as interactive activities and atomic media types such as an image or a text message. Such sharing may have a unidirectional modality, for example, one party may offer to share media and/or an activity and another party may accept or reject it. Once accepted, the media and/or activity may be available until the sharing party terminates the call or ends the sharing. Conventional mobile computing environments may be adapted to enable rapid, wide-spread adoption of these communication modalities.

Abstract: An article of manufacture for storing and dispensing perishable foods that prolongs product life and encourages portion control by dividing bulk storage into multiple sealed compartments with each compartment having an easily removable closure that prevents exposure to the environment.

Abstract: A method and apparatus are described for providing a way for a user to alleviate fear, anger, or other negative thoughts or feelings that the user has toward a specific other person, who is personally known to the user and with whom the user has previously has adverse personal interactions, or to focus such anger or negative thoughts or feelings on the second person who is an object of the user's negative feelings. This is accomplished by having the user select and display an image of the other person, so that the image is visible to the user, and also select and display an image of an object that is potentially harmful to the other person. Then the user causes the images to touch, become superimposed on, or located near one another. For example, an image of a knife is moved so that it appears that the knife stabs the image of the other person. It is then determined whether the fear, anger, or other negative thoughts or feelings of the user have been reduced. If not, the process is repeated.

Abstract: A tetrahedral junction waveguide switch having a first length of hollow rangular waveguide and a second length of hollow rectangular waveguide adjacent each other with a ferrite rod longitudinally disposed therebetween. A magnetic field is created by a superconducting switching coil placed around the junction of the two lengths of waveguide. The normally magnetically biased ferrite rod permits electromagnetic wave energy to be transmitted through the first and second lengths of waveguide. An open circuit control means selectively and controllably interrupts the current flowing around the superconducting switching coil causing the longitudinal magnetic field to be removed from the normally magnetically biased ferrite rod. The waveguide switch is thereby placed in a cut off, nontransmission, or reflective mode preventing transmission of electromagnetic wave energy.

Abstract: A microstrip transmission line substrate to substrate transition is provi comprising a pair of spaced-apart dielectric substrates having facing inner surfaces and ground planes on the non-facing outer surfaces and a parallelepiped-shaped dielectric waveguide element sandwiched between the substrate inner surfaces. The waveguide element has a pair of rhomboidal-shaped sides and a pair of sloping ends. A first microstrip conductor is disposed on the inner surface of one of the substrates and the upwardly-sloping end of the waveguide element contiguous to that surface. A second microstrip conductor is disposed on the inner surface of the other substrate and the other sloping end of the waveguide element, so that a pair of mutually-inverted microstrip transmission lines is formed. The dielectric constant of the material of the substrates is preferably much less than the dielectric constant of the waveguide element material.

Abstract: A microstrip electronic scan antenna array is provided comprising a hollow elongated octagonal-shaped housing formed by four quadrantially-disposed microstrip patch antenna arrays and four filler panels extending between the patch arrays. Three, independently-switchable microstrip Y-junction circulators are tandem interconnected in a double-ended wye configuration on a common dielectric substrate forming an octagonal end cover for the housing. Each of the three circulators acts as a single pole-double throw switch and the sequence of energization of the four microstrip patch antenna arrays is determined by controlling the sequence and direction of circulator coupling action of the three circulators.

Abstract: An rf, phase-array, microstrip antenna having a slotted ground plane mounted on one surface of a dielectric substrate. A network of strip lines is mounted on an opposed surface of the dielectric substrate. The network includes eight parallel rows of coupling strip lines mounted in superposition with eight rows of radiating slots. The slots in each row form a linear array. The slot spacing in each row is uniform and is different form different rows. The network further includes an input/output strip line, a plurality of switchable microstrip circulators and a plurality of branching strip lines connected to the circulators in a tree network. A scanning circuit is connected to the control terminals of the circulators for selectively completing an rf transmission path between the input/output strip line and the coupling strip lines. Each linear array is directional, having a major lobe, and each major lobe is oriented in a different direction.

Abstract: A millimeter wave microstrip, high reverse loss isolator is provided comprising a monolithic ferrite element disposed on one surface of a section of microstrip dielectric substrate having a ground plane on the opposite substrate surface. The ferrite element has a pair of right prism-shaped central portions each having three prism faces and two downwardly sloping transition arm portions extending radially outwardly from two of the prism faces. A bar shaped connecting arm portion interconnects the remaining prism faces of the pair of central portions. All of the top surfces of the ferrite element are covered with microstrip conductor and four sections of microstrip conductor are disposed on the surface of the substrate in alignment with the downwardly-sloping transition arm portions of the element. Permanent magnet biasing means mounted on the ground plane beneath the ferrite element central portions cause these portions to act as microstrip Y-junction circulators.

Abstract: A transitioning microstrip circulator. A Y-shaped circulator having two ps coupled to a first planar substrate and a third port coupled to a second planar substrate. The first and second planar substrates are substantially parallel and have the circulator sandwiched between them. The circulator selectively directs a millimeter wave signal along a millimeter wave transmission line to a selected port. Thereby, a signal can be coupled to circuit elements placed on each substrate. Circuit elements placed on the first and second substrate are stacked one on top of the other. This permits design flexibility and smaller packages for electronic devices.

Abstract: A composite microstrip circuit with a plurality of discrete microstrip conents made from materials having different dielectric constants mounted thereon. A transitional taper is formed on each discrete microstrip component at the point where a connection is made between other components or devices. The base on which the discrete microstrip components are positioned has a dielectric constant lower than any of the dielectric constants of the discrete components. The transitional taper results in a low cost, low loss interconnection between discrete microstrip components.

Abstract: An antenna array includes several antenna elements, each having a microstrip transmission line which includes a strip conductor and a ground plane conductor separated by a dielectric substrate; an antenna portion of the substrate being adapted to enable energy within the substrate to radiate away from the microstrip transmission line. The substrate may have greater capacitance at the antenna portion than other portions of the substrate. The antenna portion is adapted to permit RF energy to the microstrip transmission line to be directionally radiated away from the microstrip transmission line at the antenna portion, the direction of radiation being a function of the frequency of the supplied energy and the antenna slot separation. The individual antenna elements are connected, preferably in pairs, to switching elements, preferably microstrip-type circulators, providing a switchable transmission path from an RF input to a selected antenna element.

To permit frequency-scanning, the substrate has an antenna portion formed therein which is adapted to permit RF energy supplied to the microstrip transmission line to be directionally radiated away from the microstrip transmission line at the antenna portion, the direction of radiation being a function of the frequency of the supplied energy. The substrate may have greater capacitance at said antenna portion than at other portions of said substrate.
