An IV curve scan method for a photovoltaic module and an optimizer are provided. The optimizer receives an IV curve scan signal and controls an output voltage of the photovoltaic module corresponding to the IV curve scan signal to change from an open-circuit voltage to a preset minimum voltage according to a preset rule, while photovoltaic module connected to another optimizer can still operate normally, so that the system can operate normally. Then the optimizer uploads IV curve data of the photovoltaic module corresponding to the IV curve scan signal, to complete an IV curve scan on a single photovoltaic module.

An apparatus of a user equipment (UE) comprises a memory to store a Unified Radio Application and to store one or more configuration parameters for the Unified Radio Application, and one or more baseband processors to receive a radio application update from a remote server, and to update the Unified Radio Application via a Multiradio Interface (MURI) “updateRadioApps” operation with the received radio application update. One or more of the configuration parameters are maintained in the memory after the update.

The systems and methods described relate to the concept that smart devices can be used to: sense various types of phenomena like sound, blue light exposure, RF and microwave radiation, and, in real-time, analyze, report and/or control outputs (e.g., displays or speakers). The systems are configurable and use standard computing devices, such as wearable electronics (e.g., smart glasses), tablet computers, and mobile phones to measure various frequency bands across multiple points, allowing a single user to visualize and/or adjust environmental conditions.

The devices and methods leverage harmonics to resolve, separate, and identify devices. The devices and methods use the harmonic patterns associated with a frequency modulating (FM) signal to discern and extract information from the FM signal using correlation learning in a crowded spectrum space where the nodes are transmitting simultaneously on multiple channels. The methods and devices leverage harmonics to resolve, separate, and/or identify wireless communication devices.

A system and method for generating a temporal map of radio frequency (RF) signals detected from a vehicle. The method includes: detecting a plurality of RF signals over a predetermined spectrum of frequencies at a first longitude, a first latitude and a first altitude; analyzing the plurality of RF signals to determine at least a first parameter associated with at least a first RF signal of the plurality of RF signals; and adding to the temporal map the first RF signal frequency, the at least a first parameter associated with the first RF signal, the first longitude, the first latitude and the first altitude.

An apparatus and method are provided for configuring a communication link. The apparatus has a plurality of antenna elements to support RF communication over a communication link using a plurality of frequency channels, a plurality of RF processing circuits, and configuration circuitry to apply a selected configuration from a plurality of different configurations, where each configuration identifies which RF processing circuit each antenna element is coupled to, and which frequency channel is allocated to each RF processing circuit. The configuration circuitry is arranged to employ a reinforcement learning process in order to dynamically alter which of the plurality of different configurations to apply as a currently selected configuration. The reinforcement learning process comprises maintaining a future rewards record having a plurality of entries, where each entry maintains, for an associated combination of link state and configuration, an estimated future rewards indication determined using a discounted rewards mechanism. A selection policy is employed to select a configuration for a current link state, and then a new reward is observed that is dependent on how the selected configuration alters a chosen performance metric for the communication link. The estimated future rewards indication in the associated entry is then updated in dependence on the new reward. The updating comprises, when the associated entry is first encountered following a reset event, the storing in the associated entry of a predicted estimated future rewards indication generated by assuming, when using the discounted rewards mechanism, that all rewards that will be used in future to update the estimated future rewards indication in the associated entry will have the same value as the new reward.

The wireless communication method also includes receiving data to be transmitted through the uplink. The uplink is a communication link through which an external device transmits data to an aircraft.

An RFID interrogator transceiver with various improvements is proposed. A digital interface element implemented in a field-programmable gate array permits the use of a low-cost, low pin count microcontroller unit to control various integrated circuits within the transceiver both with the complexity afforded by the microcontroller unit and with the speed afforded by the field-programmable gate array. A transmit waveform generation architecture which can store opcodes in a segmented random access memory permits both leisurely loading of information over a digital interface from a low-cost microcontroller unit and fast playback over a wireless interface during low-latency RFID exchanges. Finally, a dual digital second-order resonator infinite-impulse-response filter permits a more hardware efficient channel bandpass filter solution than a finite-impulse-response filter and can be easily adjusted to accommodate RFID backscatter link frequencies and frequency tolerances.

The input data is mixed with coefficient data at layers of multiplication/accumulation processing units (MAC units).
