Abstract: Techniques provided herein employ a mesh network of wireless communication-enabled devices to monitor activity in a geographical area, such as a neighborhood or a parking lot. To this end, the mesh network monitoring system collects data about the devices found in the mesh network and establishes an expected activity level, which is used as a reference for comparing and classifying a current activity level. If the current activity level deviates significantly from the expected activity level, it may be classified as an unusual event. Upon detecting an unusual event, the mesh monitoring network may output a notification sent to the users of the devices in the mesh network. The mesh network monitoring system may help drivers determine availability of parking spots on a parking lot.

Abstract: The present disclosure relates to power management for digital-to-analog converters (DACs). As electronic devices and the components therein become increasingly smaller to satisfy the desire for more compact/portable devices, the operating voltage may be reduced to reduce the likelihood of shorts and/or voltage/current bleeds. To maintain comparable power output with the reduced operating voltage, the current may increase proportionally to the decrease in voltage. Consequently, in scaled devices and applications, high-current low-voltage regulators may be beneficial. As such, a low-dropout regulator (LDO) including one or more operational amplifiers and multiple pass devices may be implemented between a power supply and the DAC to regulate the power supply to the DAC. Moreover, the LDO may include one or more feedback loops to maintain a desired voltage regulation of the pass devices.

Abstract: A technique for selectively scrambling data obtained by electronic sensor devices, such as cameras, voice communication devices, and the like, is provided. A payload of the data is scrambled when one or more characteristics of the data indicate that the data may include sensitive information. The scrambled data is transmitted to a target device.

Abstract: Wireless communication between two electronic devices may be used to determine a distance between the two devices, even in the presence of an otherwise-disruptive attacker. A wireless receiver system of one device may receive a true wireless ranging signal from a first transmitting device and a false wireless ranging signal from an attacker. The wireless receiver system may correlate the wireless signals with a known preamble sequence and perform channel estimation using the result, obtaining a channel impulse response for the wireless signals. The wireless receiver system may filter the channel impulse response for the plurality of wireless signals by removing at least part of the channel impulse response due to the false wireless ranging signal while not removing at least part of the channel impulse response due to the true wireless ranging signal. The receiver system may perform a wireless ranging operation using the filtered channel impulse response.

Abstract: Systems and methods combine a test signal with a wanted (downlink or uplink) signal at an input of a duplexer of a communication device, and receive the test signal at an output of the duplexer. The test signal may include a radio frequency signal having less power than the wanted signal to avoid interference, or a digital signal that is added to or extracted from the wanted signal when the wanted signal does not have a radio frequency. A processor of the communication device causes the duplexer to operate in a tuning state (e.g., to transmit signals having a transmission frequency and receive signals having a receive frequency). The measurement system determines a difference or ratio in power between the test signal at the duplexer output and the duplexer input, and adjusts the tuning state based on the difference or ratio (e.g., to decrease or minimize the difference or ratio).

Abstract: A computing system includes a processor and memory. The memory includes instruction code that causes the processor to generate first and second parser instances and associate the first parser and the second parser with respective first and second search queries. The processor controls the first parser to repeatedly obtain data from the data stream in blocks until the first parser finishes identifying elements in the data stream associated with its search path. The processor controls the second parser to repeatedly obtain blocks from the first parser when the blocks obtained by the first parser have not been searched by the second parser, and controls the second parser to obtain blocks from the data stream when the blocks obtained by the first parser have been searched by the second parser and the first parser has finished searching.
