Abstract: Techniques are disclosed for systems and methods to provide accurate, low lag, and reliable autopilot autorelease in a hydraulic steering system for mobile structures. A hydraulic steering system includes a logic device configured to communicate with an autopilot pump controller, a control surface reference sensor, an orientation sensor, and/or a gyroscope. Control and sensor signals provided by the pump controller and/or the various sensors are used to selectively enable and/or disable an autopilot release signal. The autopilot release signal enables or disables the autopilot pump controller and/or an autopilot pump, or controls the autopilot pump controller to enable or disable the autopilot pump.

Abstract: A fuel water separator filter is described that is configured as a filter-in-filter construction with multiple water separating layers to separate water from the fuel. The fuel water separator filter is configured for use on a suction side of a fuel pump, and includes a neck with a radially outward facing seal that in use seals with the filter housing. The filter housing is formed with an isolated water sump that in use is isolated from water that is stripped from the fuel by the first stage of the outer filter. The isolated water sump is formed by a wall within the housing, instead of relying on an outer diameter seal on the filter to form the water sump.

Abstract: Techniques are disclosed for systems and methods to provide casting guidance for users of mobile structures, including watercraft. A casting guidance system includes a sonar transducer assembly and a logic device configured to communicate with the sonar transducer assembly. The sonar transducer assembly is adapted to be mounted to a mobile structure and placed in a body of water. The logic device is configured to identify one or more underwater targets in sonar data received from the sonar transducer assembly, determine casting guidance parameters corresponding to the one or more identified underwater targets, and generate at least one casting guidance identifier based, at least in part, on the determined casting guidance parameters. Subsequent user input, the sonar data, and/or the casting guidance parameters may be used to adjust a steering actuator, a propulsion system thrust, and/or other operational systems of the mobile structure.

A pilot instruction is received and a control signal for the aircraft is generated using the pilot instruction and the aircraft movement limit.

Abstract: In a switching module structure that includes a low-impedance path to ground, such as a parasitic capacitance of an insulating substrate, a further insulating substrate presenting a parasitic capacitance placed in series with the low impedance current path and a connection of a conductive layer to input voltage rails using a single decoupling capacitor or, preferably, a midpoint of the voltage rails formed by a series connection of decoupling capacitors maintains a large portion of common mode (CM) currents which are due to high dV/dt slew rates of SiC and GaN transistors within the switching module.

Abstract: A packet transfer buffer for use in a computer system having multiple source and destination inferfaces, as well as packet handling software. The buffer has a source packet FIFO and destination packet FIFO, each with an associated packet length counter. The packet handling software obtains packet lengths from the source packet counter, and provides the packet length to the destination packet counter. The buffer has hardware circuitry that handles transfer of data from the source packet FIFO to the destination packet FIFO without the need for word-by-word reads and writes by the packet handling software.

The receptacle includes a platform (i) for exposure external to the lighting fixture and (ii) providing connectivity for coupling to an external control device and a base operationally coupled to the platform and including a first set of one or more nodes configured for coupling to a first set of wires.

Abstract: Sensor information is obtained from a downward facing sensor coupled to an aircraft. A new position is determined using the sensor information, including by: obtaining directional information associated with the aircraft's direction of flight, obtaining a previous position associated with the aircraft, filtering a plurality of datasets in a ground feature database using the directional information and the previous position in order to obtain a reduced group of datasets (where each dataset in the ground feature database is associated with a known in-air position), and comparing the sensor information against the reduced group of datasets in order to determine the new position.

Abstract: Systems and methods for measuring plant leaf gas exchange based on instantaneous mass balance in the sample chamber. The response of leaf net assimilation rate (Anet) to computed leaf internal CO2 concentration (Ci) is measured by continuously varying the input CO2 concentration and measuring the continuous difference between chamber input (reference) and output (sample) concentrations to compute a continuous series of Anet values, which can then be plotted against computed Ci. When combined with a similar response test using an empty chamber test to allow for sample chamber mixing and/or gas analyzer match dynamics and/or small flow-related residual time delays, such method provides accurate and rapid A Ci response (RACiR) curves in a much shorter time than conventional methods.

Abstract: Techniques are disclosed for systems and methods for navigating mobile structures. The mobile structure may include a main attitude & heading reference system (AHRS) and one or more devices. The one or more devices may include a slave AHRS such as a gyroscope. Data may be transmitted from the main AHRS to the one or more devices through a network. Latency may be present in the transmission of data. As such, data from the slave AHRS may be used to determine changes in heading and/or attitude of the mobile structure to compensate for such latency. In addition, such data may be used to determine changes in wind direction and/or heading experienced by the mobile structure.

Abstract: Methods and systems for reliable broadcasting that use re-transmissions, in a multi-hop, time-slotted wireless network, is presented. The methods and systems evaluate the trade-off between power consumption and communication reliability, and are consequently able to provide increasing degrees of robustness for broadcasts in the wireless network. Embodiments of the present invention are able to incrementally use re-transmissions, therein trading-off battery life for an increased message completion rate or a lower packet error rate, for example, in order to reliably broadcast critical or high-priority message network-wide.

The stand may elevate the track above the base to permit water to flow underneath the track.
