Abstract: Systems and methods for using ranging signals with cellular devices. The ranging signals may utilize ranging slots and resources at least partially allocated by a cellular network. The resources may include frequencies used for uplink or downlink communications between the cellular network and the cellular devices. Alternatively, the resources may include frequencies outside of a spectrum used for communication between the cellular network and the cellular devices.

Abstract: The current disclosure is related to a column and line digital-to-analog converter (DAC) with a hybrid coupler for generating quadrature analog signals. The DAC may include an array of unit power amplifiers (cells). A first portion of the cells of the array may be coupled to a first column decoder to receive in-phase components of digital signals and a second portion of the cells may be coupled to a second column decoder to receive quadrature components of the digital signals. The first portion of the cells of the array may generate in-phase components of analog signals and the second portion of the cells of the array may generate quadrature components of the analog signals. A hybrid coupler of the DAC may receive the in-phase and quadrature components of the analog signals with a similar phase, delay the quadrature components by a phase delay (e.g., 90 degrees), and output the resulting analog signals.

Abstract: A system may include a processor that may receive account information having a plurality of transactions associated with a bank account. The processor may then determine an expected burn rate of funds based on the account information, determine an expected savings balance at a first time based on the account information and the expected burn rate, generate an event in response to the expected savings balance being below a threshold, and send an alert including the event to a computing device associated with the user. The alert may indicate a status of the expected savings balance via an electronic display of the computing device.

Abstract: A charger for a battery power system can include first and second switching bridges with inputs couplable to an AC source, at least one transformer having two or more primary windings (connected in series and coupled to the switching bridges) and at least two secondary windings, and second rectifier/chargers, each coupled to at least one of the secondary windings and couplable to at least one battery. The switching bridges may be respectively operable during positive and negative half cycles of the AC source to deliver an AC voltage to the transformer. The rectifier/chargers may be operable in a first mode to receive an AC voltage from the transformer and deliver a DC voltage for charging the respective battery. In some multi-battery embodiments, the rectifier/chargers may also be operable in a second mode to deliver an AC voltage from a respective battery to the transformer to balance charge between the batteries.

Abstract: Frequency-filtering circuitry is disclosed that rejects power of a wireless signal having an undesired frequency while causing a decreased power loss to a wireless signal having a desired frequency using distributed elements, rather than lumped elements. The frequency-filtering circuitry may reject at least 5 decibels of power of a wireless signal having a frequency over 32 gigahertz, while causing a power loss of at most 1.1 decibels to a wireless signal having a frequency lower than 29.5 gigahertz. The frequency-filtering circuitry may include a main branch, a first parallel branch coupled and parallel to the main branch via a first connecting trace, and a second parallel branch coupled and parallel to the main branch via a second connecting trace. The first connecting trace intersects the main branch and the first parallel branch, and the second connecting trace intersects the main branch and the second parallel branch.

Abstract: A server receives a first hypertext transfer protocol (HTTP) from a client device requesting for content associated with a webpage. The server retrieves a plurality of cache keys associated with respective sets of application metadata identified in the first HTTP request from an application metadata database and transmits the cache keys to the client device. The server receives a second HTTP request from the client device identifying one or more cache keys that are not stored in a local HTTP cache of the client device. The server device retrieves the sets of application metadata corresponding to the missing cache keys from the application metadata database and transmits the application metadata to the client device.
