Abstract: A radar system including a transmit antenna for transmitting a radio frequency (RF) signal or a radar signal and a receive antenna for receiving a plurality of reflected signals created by a plurality of targets reflecting the RF signal or radar signal. The reflected signals include noise. The radar system also includes an analog-to-digital converter (ADC) that digitizes or samples the reflected signals to provide a digitized or sampled noisy input signal. The radar system further includes a reservoir computer that receives the noisy input signal. The reservoir computer includes a time-varying reservoir and is configured to de-noise the noisy input signal and provide a range measurement for each of the plurality of targets.

Abstract: Methods and devices provide access to a sponsored data service (SDS) from a mobile device. A method may include generating a play media command that includes a remote media address and an SDS identifier, and converting the remote media address into a local media address. The method may further include requesting media from an internal content server via the local media address, where the internal content server resides within the mobile device. The method may include determining if the requested media is stored on the internal content server, obtaining the requested media from the internal content server upon determining that the requested media is stored within the internal content server, and playing the requested media on a mobile media player.

Abstract: Disclosed are mechanisms for sharing managed content through external systems. A sharing module publishes content in a share and metadata associated therewith to an external system. The share represents a folder or directory in a repository managed by an information system such as an enterprise content management system. The publication is made possible through application programming interface (API) calls handled by a first sharing module API, a repository API, a second sharing module API, and an external system API. These APIs together provide a one-to-one mapping of communications protocols used by the managed repository and the external system. The share in the managed repository and the share published to the external system are synced and any conflict between the two is detected and resolved. The shared content can be repatriated back to the managed repository and the shared version deleted from the external system.

Abstract: Systems and methods according to one or more embodiments are provided for mapping and registration of synthetic aperture raw radar data to aid in SAR-based navigation. In one example, a SAR-based navigation system includes a memory including executable instructions and a processor adapted to receive phase history data associated with observation views of a scene. The processor further converts the received phase history data associated with the observation views to a range profile of the scene. The range profile is compared to a range profile template of the scene to estimate a geometric transformation of the scene encoded in the received phase history data with respect to a reference template.

Abstract: A device determines a connection status of a Public Land Mobile Network (PLMN) communication interface and a wireless Local Area Network (LAN) communication interface, and stores the connection status in a queue. The device waits, subsequent to storing the connection status, for expiration of a time delay; and retrieves, subsequent to the expiration of the time delay, the connection status or another connection status from the queue. The device sends, based on the retrieved connection status or the other connection status, a service validation request to a server associated with the PLMN, and receives from the server, in response to the service validation request, a validation response that authorizes service delivery to the device via a PLMN.

Abstract: A device can receive, from a set of storage devices, first information relating to one or more pilot data plans that are associated with one or more first groups of user devices. The device can receive, from the set of storage devices, second information relating to one or more live data plans that are associated with one or more second groups of user devices. The device can analyze the first information and/or the second information to identify one or more patterns of information. The one or more patterns can include a data usage pattern, a demographic information pattern, a revenue generation pattern, and/or a user interest pattern. The device can perform one or more actions, including generating a new data plan, identifying one or more user accounts as candidates for a new data plan, and/or transmitting, via a network, information relating to the new data plan.

Abstract: A device may receive, from a user device, a hypertext transfer protocol (HTTP) CONNECT request that includes a uniform resource locator (URL). The device may determine, using a data structure, whether the URL is a sponsored URL or a non-sponsored URL. The data structure may include one or more sponsored URLs associated with a toll-free data service campaign. The device may establish an HTTP CONNECT tunnel for transferring traffic, associated with the URL, between the user device and another device. The device may monitor data use, associated with the HTTP CONNECT tunnel, based on determining whether the URL is a sponsored URL or a non-sponsored URL. The device may generate a traffic information record based on monitoring the data use, and the device may provide the traffic information record to the user device.

Abstract: An audio processor may process dissimilarly formatted digital audio signals and produce an analog output for reproduction by a transducer, such as a speaker. The audio processor may be, for example, a digital-to-analog converter (DAC) with multiple digital inputs and a single analog output. The audio processor may also include other components, such as processing components, filters, equalizers, amplifiers, and the like. The audio processor may process audio, such as high fidelity DSD audio and lower fidelity PCM audio, and combine the differently formatted data into a single output. During processing, the audio processor may manipulate the different audio signals, such as by ducking a music playback to allow a notification sound to be played.

Abstract: The behavior of a NOS DAC and an analog filter may be emulated by electronic components of an integrated circuit (IC) by upsampling data and applying a digital filter to the upsampled data. For example, the IC may include a zero-order-hold circuit that upsamples data from a first input sample rate to a second, higher input rate. The upsampled data may be passed to an Asynchronous Sample Rate Converter (ASRC) that performs further upsampling (e.g., from 8*Fs-64*Fs). The upsampled data may be passed to a digital low pass filter. The digital low pass filter may emulate, for example, a response of a fifth order Butterworth analog filter to mimic the effect of analog processing. The IC may integrate the upsampling circuit, the low pass digital filter, a digital-to-analog converter (DAC) and an amplifier to provide an audio solution for playing high-fidelity music in a mobile device.

Abstract: A device intercepts a request that includes a network address or a universal resource locator (URL) for a landing page and determines whether special handling is applicable when forwarding the landing page to the requesting device. When the special handling is applicable, the request is automatically redirected to a validation device, which determines whether the requesting device is eligible for the special handling. The validation device signs based on the determination and returns the signed request to the requesting device. The requesting device forwards the signed request to request the landing page and the special handling is selectively applied based on the signed request.

Abstract: A system and method utilize multiple, asynchronous, voltage isolated integrated power data circuits (IPDCs) to respectively determine one or more power parameters of a multi-phase power distribution system. In at least one embodiment, the power parameters represent differences between voltage phases of a multi-phase power distribution system. In at least one embodiment, the IPDCs each sense a voltage or current from a single phase of a three-phase power distribution system. Additionally, the IPDCs are electrically isolated from each other and, thus, in at least one embodiment, can utilize voltage divider or shunt resistor sensing without being subject to high voltages representative of the difference between voltage phases. Additionally, in at least one embodiment, each of the IPDCs utilizes a separate clock signal to determine phase sequence and phase angle deltas of one or more three phase voltages of the three-phase power distribution system.
