    Abstract: A ride system includes a track and an overhung ride assembly. The overhung ride assembly includes a transport platform coupled to the track, a ride vehicle, and a heave system extending between the transport platform and the ride vehicle. The heave system is configured to heave the ride vehicle relative to the transport platform. The heave system includes an extendible tube defining a variable volume configured to store a gaseous fluid. The extendible tube is configured to extend in response to a lowering of the ride vehicle away from the transport platform by the heave system such that the gaseous fluid within the variable volume of the extendible tube provides a fluid force that biases the extendible tube toward a contracted configuration to assist the heave system with a lifting of the ride vehicle toward the transport platform.

    Abstract: The virtual queue system includes a virtual queue controller comprising a processor and a memory, wherein the memory stores instructions executable by the processor and is configured to receive a request, the request being associated with an individual guest, for a position in a virtual queue of an attraction, assign the individual guest to the position in the virtual queue in response to the request, receive ride schedule data for the attraction comprising information about a change in status of individual rides of the attraction, and determine a wait time for the individual guest for the attraction based at least on the position of the individual guest in the virtual queue, the ride schedule data, and historical guest throughput at the attraction. The virtual queue system is further configured to output a signal to a guest-associated device indicating the wait time for the attraction.

    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: 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 wireless power transmitter can include a wireless power transmitter coil adapted to magnetically couple the wireless power transmitter to a wireless power receiver, a resonant capacitor coupled to the wireless power transmitter coil to form a resonant circuit, and an inverter having an input that receives a DC voltage and an AC output coupled to the resonant circuit. The inverter can further include a plurality of switching devices coupled between the input and AC output of the inverter, a controller configured to generate pulse width modulated (PWM) drive signals for the plurality of switching devices, wherein the PWM drive signals are tri-state PWM signals having three output levels, and zero crossing detection circuitry that receives the PWM drive signals for corresponding switching devices and signals corresponding to voltages across the corresponding switching devices and generates gate drive signals for the corresponding switching devices.

    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.
