Abstract: Techniques are disclosed for systems and methods to provide accurate and reliable compact sonar systems for mobile structures. A sonar system includes multiple sensor channels, each comprising a sonar transmitter and a sonar receiver, and a logic device configured to provide control signals and receive sensor signals from the sensor channels. The logic device is configured to provide transmission signals to sonar transducer assemblies, where signal patterns of the transmission signals are differentiated based at least in part on frequency content. Acoustic returns are processed using the signal patterns to reduce inter-channel pickup between the sensor channels. Resulting sonar data and/or imagery may be displayed to a user and/or used to adjust a steering actuator, a propulsion system thrust, and/or other operational systems of the mobile structure.

Abstract: A method for controlling a light source of a display is provided. In the method, maximum frame rates are determined for different portions of video content to be displayed on the display.

The light source of the display is controlled to not blink when a second portion of the video content having a second maximum frame rate is displayed. The video content is displayed at the maximum frame rates and in the high dynamic range.

Abstract: A method, system, and computer readable medium for managing applications on an application execution system are disclosed. On an application server the number of instances of a first application type that are in a busy state is determined. This determination is performed at each respective time interval in a plurality of time intervals. Then, a first running average for the busy state of the first application type is computed based upon the number of instances of the first application type that are in a busy state, at the application server, at each respective time interval. A removal request is sent when the first running average for the busy state meets a first removal criterion. The removal request is a request to remove the application server from a data structure that specifies which of a plurality of application servers accept service requests for the first application type.

Abstract: A brownfield security gateway is configured to support a trusted execution environment (TEE) that employs cryptographic and physical security—which forms a trusted cyber physical system—to protect sensitive transmissions on route to a controllable device. The gateway may be implemented with a System on Chip (SoC) that utilizes an application layer gateway to filter content within a transmission. When the application layer gateway authorizes the transmission, the transmission is forwarded to a trusted peripheral device that is configured with communication transport protocols, and the trusted peripheral device transfers the transmission to the controllable device. The trusted peripheral device and the controllable device are physically protected by, for example, protected distribution systems. Accordingly, the trusted peripheral device functions as a gateway between the SoC and the controllable device.

Power calculation logic for determining power applied to the crank arm is then updated using the zero offset value.

Abstract: Devices for producing vacuum using the Venturi effect have a housing that defines a suction chamber, a motive passageway converging toward the suction chamber, a discharge passageway diverging away from the suction chamber, and a suction passageway having a first port in fluid communication with the suction chamber. Within the suction chamber, a motive exit of the motive passageway is spaced apart a distance from a discharge entrance of the discharge passageway to define a Venturi gap. A fletch that has a first hollow body section that terminates at or proximate a motive exit and a second hollow body section that terminates with a fletch entrance in fluid communication with the suction passageway upstream of the first port is present in the motive passageway. During operation, fluid flow through the motive passageway draws fluid flow through the first port into the suction chamber and through the fletch.
