Abstract: The present invention provides a method for aligning spans using real-time kinetics (RTK) data communicated through a power line carrier system.

Abstract: The present disclosure is generally directed to an adjustable speed irrigation system having a control panel, at least one water conduit, at least one tower, and a position sensor. A user inputs a user-defined end destination at the user-defined arrival time into the control panel. The control panel receives a current position of the irrigation system from the position sensor. The control panel compares the current position to the user-defined end destination and calculates a new optimum ground speed required to reach the user-defined end destination at the user-defined time based on the current position of the irrigation system. The control panel then sends a signal to a speed control unit to adjust the speed of the irrigation system to match the new optimum ground speed.

Abstract: Described is a fitting for coupling fluidic paths which facilitates secure and low leak rate fluid flow through a fluidic path junction such as a junction in a liquid chromatography system or other chemical analysis instrument. Fluid containing various mixtures of chemical samples can pass through the junction at high pressure with little or no trapped residue remaining in a volume at the connection. According to various embodiments, a face seal is achieved between two separate fluidic path features. In some embodiments, the sealing of the fluidic paths is aided by the use of a compliant polymer seal. The seal facilitates intimate contact between adjacent surfaces and significantly limits or prevents the entry of fluid under high pressure into an unswept volume. Thus the risk of carryover and its adverse effect on measurements is reduced or eliminated.

Abstract: A pin valve assembly and a method of controlling the flow of fluids comprising a pin block housing pin valves, a fluid plate with a fluid channel for fluidically communicating with the pin valves, and a fitting block housing fittings for fluidic communication with the fluid plate and for fluidic communication with fluidic components. The fluid flow through the channels of the fluid plate are controlled by the fluidic components and the pin valves.

Abstract: A vehicle computer system has an audio entertainment system implemented in a logic unit and audio digital signal processor (DSP) independent from the host CPU. The audio entertainment system employs a set of ping/pong buffers and direct memory access (DMA) circuits to transfer data between different audio devices. Audio data is exchanged using a mapping overlay technique, in which the DMA circuits for two audio devices read and write to the same memory buffer. The computer system provides an audio manager API (application program interface) to enable applications running on the computer to control the various audio sources without knowing the hardware and implementation details of the underlying sound system. Different audio devices and their drivers control different functionality of the audio system, such as equalization, volume controls and surround sound decoding. The audio manager API transfers calls made by the applications to the appropriate device driver(s).

Abstract: A coupling mechanism is provided for coupling an expansion device in a liquid refrigerant line of a refrigeration system. The coupling mechanism permits the expansion device to be removably coupled to the liquid refrigerant line, thereby permitting the expansion device to be easily decoupled and recoupled to the liquid refrigerant line.
