Abstract: Methods, systems, and apparatuses are described herein for improving computer authentication processes by generating authentication questions based on the location of a user. Transaction data indicating a plurality of transactions associated with a user account may be received. Location data indicating a plurality of locations of a user device might be received. At least a subset of the plurality of transactions may be tagged, based on the location data, with an indication that a user was present for a respective transaction. For example, a location of a merchant might be compared to a user device location indicated by the location data. A plurality of authentication questions might be generated based on the subset of the plurality of transactions. Access to the user account might be provided based on responses to the plurality of authentication questions.

Abstract: A computing system acquires a plurality of gig-income models for a plurality of gig-workers, and each of the plurality of gig-income models includes a corresponding expected income for a respective gig-worker of the plurality of gig-workers over a period of time. The computing system identifies groups of gig-workers to join an income float pool based on the gig-income models of the gig-workers. The computing system transfers funds into or out from an account associated with a gig-worker in the income float pool in response to detecting, from one or more data sources, a difference between an actual income and an expected income of the gig-worker during an additional period of time. Thus, the gig-worker receives a relatively stable income.

The process may include receiving at least one request for each of a plurality of time blocks of a template; querying a catalog of songs and/or song portions in a database to compile a candidate list of songs and/or song portions that substantially meet the at least one request of a first time block of the plurality of time blocks; choosing a first song portion and a second song portion from the candidate list for the first time block; compiling the first song portion and the second song portion to form at least a portion of the first time block, including blending a temporal length of the first song portion and the second song portion; and generating an audio file with the plurality of time blocks.

Abstract: Disclosed is a decoupling dipole structure that renders a midband dipole effectively transparent to a nearby lowband dipole. This not only improves the beam quality in the lowband without sacrificing beam quality in the midband, it also enables different lowband dipoles to be employed to customize the lowband performance of the multiband antenna without requiring a redesign of the midband dipoles or of the array face.

Abstract: A wireless device may detect a beam failure of a serving beam set. In response to detecting the beam failure, the wireless device may select a first candidate beam set from candidate beam sets based on a priority order of the candidate beam sets, wherein each candidate beam set, of the candidate beam sets, comprises reference signals (RSs). The wireless device may select a first candidate RS from candidate RSs associated with the first candidate beam set based on a channel quality of the first candidate RS being greater than a threshold. The wireless device may transmit a preamble associated with the first candidate RS for beam failure recovery.

Abstract: Systems and methods are described for radio frequency (RF) calibration in a multiple antenna system (MAS) with multi-user (MU) transmissions (“MU-MAS”) exploiting uplink/downlink channel reciprocity. The RF calibration is used to compute open-loop downlink precoder based on uplink channel estimates, thereby avoiding feedback overhead for channel state information as in closed-loop schemes. For example, a MU-MAS of one embodiment includes a wireless cellular network with one or multiple beacon stations, multiple client devices and multiple distributed antennas operating cooperatively via precoding methods to eliminate inter-client interference and increase network capacity.

Abstract: In some embodiments, an authentication system may be configured to process one or more tokens that incorporates one or more tailored-wavelength-range coded patterns, codes represented within a steganographic image, or “overlapping” codes. As an example, such a token may include (i) one or more invisible-ink-printed patterns printed using infrared ink corresponding to different tailored wavelength ranges within the infrared light spectrum, (ii) one or more steganographic images in which invisible-ink-printed patterns are interweaved within the steganographic images, (iii) visible-ink-printed patterns and invisible-ink-printed patterns printed substantially within the visible ink portions of the visible-ink-printed patterns, or (iv) other features, where the invisible-ink-printed patterns correspond to one or more authentication codes or other data for token authentication.

Abstract: For a coding block of an image, a luma prediction block is generated, a luma residual block is generated, a quantized luma block is generated after transforming the luma residual block using a luma transform type, and the quantized luma block is entropy encoded. A chroma prediction block is generated, a chroma residual block is generated, an initial chroma transform type for the chroma residual block is determined as the luma transform type, a quantized chroma block is generated using the chroma residual block transformed by a final chroma transform type, and the quantized chroma block is entropy encoded. When the initial chroma transform type is other than a default transform type, the final chroma transform type is the initial chroma transform type or the default transform type, and quantized coefficients of the quantized chroma block depend upon quantized coefficients of the quantized luma block.

Abstract: A renewable power system with a twin-configurable architecture is described. The system includes a renewable energy source (RES), an energy storage system (ESS), and at least one controllable load (CL) (e.g., AI training/datacenter). The system can serve as a baseload or semi-baseload plant for CL(s) and/or as a peaker or semi-peaker plant for an electric grid, or vice-versa, and optionally in parallel, can also provide ancillary services to the electric grid and/or to the CL(s). In certain embodiments, e.g. solar PV RES(es), the system can have capacity factors of at least about 60% and up to 100%, higher asset utilization, better economics for the RES-ESS, improved system performance, and lower energy costs as compared with known systems without a CL(s). By making load a variable, and integral part of the system, sophisticated resource allocation strategies, including AI algorithms, can be developed not previously possible with known systems lacking a CL(s).

Additionally, the method includes determining a similarity value based on the first vector space distance and the second vector space distance.
