Abstract: A system and method for calculating a draft/freeboard for a vessel. The system includes multiple sensor units, wherein each sensor unit includes a housing; a distance sensor to sense a freeboard from various positions in the vessel. The sensor unit includes a coupling member, such as magnets coupled to the housing that allow the sensor units to be mounted to the vessel. The sensor units can connect to a control unit for processing data and presenting the measurements. The system can calculate drafts from the freeboard data, wherein the freeboard data can be determined from different positions of the vessel.

Abstract: It is desirable for interrupt handling routines to be aware of the interrupt latency—the time between a interrupt request is received and the time when the interrupt service routine begins executing. A method is shown wherein the latency is measured by a dedicated counter and is available to the interrupt service routine. Alternately, a threshold may be set indicating the maximum acceptable latency and the interrupt service routine is signaled when said maximum is reached.

Abstract: Methods and apparatus for power monitoring with sequencing and supervision are disclosed. An example method disclosed herein includes supervising a first power rail and a second power rail, sequencing a first enable signal associated with the first power rail and a second enable signal associated with the second power rail, and determining whether the first power rail is enabled based on regulation information determined while supervising the first power rail.
