Abstract: System and method for providing a measurement module (MM) interface for configuring a measurement system. The method includes creating a MM and one or more MM interface programs implementing respective MM interface protocols (MMIP) for the measurement module.

A MM is installed in the measurement system and provides ID to a carrier unit of the system. The MMIP server is accessed and, based on the ID, payment information, etc., a MM interface program is downloaded and used to configure the carrier unit to enable communication with the MM in performing a task.

Abstract: A system and method for configuring a device to perform a function, where the device includes a programmable hardware element and one or more fixed hardware resources. A program is stored which represents the function. A hardware configuration program is generated based on the program, specifying a configuration for the programmable hardware element that implements the function, and usage of the fixed hardware resources by the programmable hardware element in performing the function. A deployment program deploys the hardware configuration program onto the programmable hardware element, where, after deployment, the device is operable to perform the function, where the programmable hardware element directly performs a first portion of the function, and the programmable hardware element invokes the fixed hardware resources to perform a second portion of the function. An optional measurement module couples to the device and performs signal conditioning and/or conversion logic on an acquired signal for the device.

Abstract: A method for operating a system that includes several subsystems may involve establishing one or more synchronized timelines for the system; allocating timeslots within each of the timelines for operation of one or more devices in the system; detecting an input event asynchronously to the timeline; generating a timestamp indicative of the time at which the input event is detected relative to the timeline; performing a processing task in response to the input event during a time slot allocated to the processing task; and inhibiting generation of an output event until a second time relative to the timelines. Performing the processing task may generate data representative of the output event as well as data representative of the second time. The second time may be a pre-determined time interval after the input event detection time.

Abstract: A computer system is programmed by a user to perform dataflow computations by constructing a dataflow block diagram that utilizes function icons. At least a subset of the function icons are polymorphic with respect to data type and with respect to data aggregation. A polymorphic function icon is executed by performing a single mathematical operation when its inputs are scalars, while the same icon is executed on an element when its inputs are arrays or a scalar and an array. With cluster inputs, the polymorphic function icon is executed on a component by component basis. Output types of polymorphic function icons are determined by their input types prior to executing the diagram. The system automatically constructs a connection diagram consisting of an icon with connection points that are labelled with the names of associated front panel controls and indicators. A front panel control can be hidden to make the associated control value a constant.
