A railcar with discharge control system is disclosed. In one embodiment, a railway car includes an underframe and at least one hopper for transporting lading. The railway car further including the underframe including a center sill which defines in part a longitudinal axis of the railway car. A discharge opening formed proximate to a lower portion of the hopper. A respective door assembly pivotally mounted adjacent to the discharge opening to control the flow of lading from the hopper. The door assembly operable for movement between a first, closed position and a second, open position relative to the discharge opening. A discharge control system operable to move the door assembly between the first position and the second position. The discharge control system operably moves generally longitudinally along the axis of the railway car to move the door assemblies between the first, closed position and the second, open position.

An in-vivo sensing device having multiple imagers controlled by a single processor and a method for communicating between the processor and the imagers. The processor and imagers are connected via common data and control busses, instead of by direct separate conducting lines thereby reducing the number of pins on the processor and the corresponding number of conducting lines.

An application programming interface (API) for synchronizing multiple devices in a system. The API includes a plurality of functions invocable in a program to synchronize multiple devices, where each function is executable to perform a respective functionality related to synchronizing the devices, and at least one of the functions is executable to access a plurality of instrument drivers corresponding respectively to the plurality of devices to synchronize the plurality of devices. In synchronizing the plurality of devices, the functions determine a trigger clock signal for each of the plurality of devices, and synchronize the plurality of devices based on the determined trigger clock signals. The API also includes a plurality of attributes corresponding to respective properties of the system related to synchronization of the devices, including one or more trigger attributes and / or one or more trigger clock attributes for each of the devices. The API representations may be text-based and / or graphical.

Interference in ultrasound imaging when used in connection with high intensity focused ultrasound (HIFU) is avoided by employing a synchronization signal to control the HIFU signal. Unless the timing of the HIFU transducer is controlled, its output will substantially overwhelm the signal produced by ultrasound imaging system and obscure the image it produces. The synchronization signal employed to control the HIFU transducer is obtained without requiring modification of the ultrasound imaging system. Signals corresponding to scattered ultrasound imaging waves are collected using either the HIFU transducer or a dedicated receiver. A synchronization processor manipulates the scattered ultrasound imaging signals to achieve the synchronization signal, which is then used to control the HIFU bursts so as to substantially reduce or eliminate HIFU interference in the ultrasound image. The synchronization processor can alternatively be implemented using a computing device or an application-specific circuit.

Apparatus, system and method for synchronizing one or more clocks across a communication link. A slave clock may be synchronized to a master clock by means of a synchronization signal sent from the master to the slave clock side of the link. The synchronization signal may be an expected signal pattern sent at intervals expected by the slave side. The slave clock may correlate received signals with a representation of the expected synchronization signal to produce a correlation sample sequence at a first sample rate which is related as n times the slave clock rate. The synchronization signal receipt time indicated by the correlation sample sequence may be refined by interpolating the correlation sample sequence around a best correlation sample to locate a best interpolation at an interpolation resolution smaller than the sample resolution. The best interpolation may in turn be further refined by estimating between interpolator outputs adjacent to the best interpolation output. The synchronization signal receipt time thus determined is compared to the expected time based upon the slave clock, which is adjusted until the times match. After initialization, all slave clock errors are preferably accumulated to prevent long-term slip between the slave and master clocks. Formerly independent master and slave clocks synchronized across the communication link constitute a noncommon clock which may be compared on each side of the link to secondary independent clocks, and the secondary independent clocks may then be separately synchronized by adjusting one to have the same difference from its local noncommon clock as the secondary clock on the other side of the link has from its local noncommon clock.
