Portable phased array test instrument
Inventive features of a portable ultrasonic phased array test instrument are disclosed. The instrument has a battery rack that can be repurposed to host a re-programming module for testing and re-programming electronic components.
1. An instrument comprising:
electronic components;
at least one battery;
an instrument casing having a battery cavity for holding the at least one battery;
a re-programming connector connected to the electronic components and attached to the casing such that a first set of conductive contacts is substantially co-planar with a surface of the battery cavity;
a re-programming module comprising:
a spring contact connector having a second set of conductive contacts; and,
a cable connector; and,
wherein the re-programming module is configured to be inserted into the battery cavity in place of the battery, such that the second set of contacts makes electrical contact with the first set of contacts.
2. The instrument of claim 1 wherein the re-programming connector comprises a printed circuit board (PCB) and the first set of conductive contacts comprises a set of flat conductive traces on a surface of the PCB.
3. The instrument of claim 1 wherein the re-programming connector is a Joint Test Action Group (JTAG) connector.
4. The instrument of claim 1 wherein the cable connector has cable contacts for a computer cable, each of the cable contacts being electrically connected to a corresponding one of the second set of contacts.
5. The instrument of claim 4 wherein, when the re-programming module is inserted into the battery cavity, the computer cable is connected to the cable connector at a first computer cable end and to a computer at a second computer cable end.
6. The instrument of claim 5 wherein the electronic components comprise re-programmable electronic components and the computer is configured to re-program the re-programmable electronic components.
7. The instrument of claim 5 wherein the electronic components comprise testable electronic components and the computer is configured to test the testable electronic components.
8. The instrument of claim 1 , wherein the electronic components are configured to control emission of non-destructive testing energy and to receive and process response signals of the testing energy.
9. The system of claim 1 , wherein the electronic components comprise at least one ultrasonic acquisition unit.
10. The system of claim 1 , wherein the electronic components comprise at least one eddy current controller unit.
