Abstract

System and method for measurement, DAQ, and control operations which uses small form-factor measurement modules or cartridges with a re-configurable carrier unit, sensors, and a computer system to provide modular, efficient, cost-effective measurement solutions. The measurement module includes measurement circuitry, e.g., signal conditioner and/or signal conversion circuitry, and interface circuitry for communicating with the carrier unit. The module communicates interface information to the carrier unit, which informs the computer system how to program or configure a functional unit on the carrier unit to implement the communicated interface, or sends the information directly to the computer system. The computer system programs the carrier unit with the interface, and the programmed carrier unit and measurement module together function as a DAQ, measurement, and/or control device. The carrier unit may receive multiple cartridges, each having a respective interface protocol, where the carrier unit is configurable to support the respective protocols sequentially and/or in parallel.

Claims

1. A programmable hardware element (PHE), wherein the PHE comprises:

a first one or more portions, each configured to implement a cartridge controller operable to provide an interface between controlling software and a respective cartridge, wherein each of the first one or more portions includes a memory;

wherein each cartridge controller is operable to;

detect coupling of the respective cartridge to the PHE;

query the respective cartridge for configuration information of the respective cartridge;

store program instructions in the memory implementing a first respective interface protocol based on the configuration information; and

establish communication with the respective cartridge according to the first respective interface protocol; and

wherein the PHE is operable to control one or more cartridges coupled to the PHE.

2. The PHE of claim 1, wherein each cartridge controller is further operable to:

request the program instructions from a host computer coupled to the PHE; and

receive the program instructions from the host computer and store the program instructions in the memory.

3. The PHE of claim 1, wherein each cartridge controller is further operable to:

request the program instructions from the PHE; and

receive the program instructions from a second portion of the programmable hardware element and store the program instructions in the memory of the respective cartridge controller.

4. The PHE of claim 1, wherein each cartridge controller is further operable to:

request the program instructions from a computer coupled to the PHE over a network; and

receive the program instructions from the computer over the network and store the program instructions in the memory.
