Open the CIPO recordAbstract From the Canadian patent
A dual-pin probe (100) has a probe body (104) a probe head (102), a signal , pin (120) and a ground pin (122). The probe body couples to a robotic system configured to manipulate the dual-pin probe relative to a circuit board under test. The probe body is coupled to the probe head. The signal pin and the ground pin extend from a face of the probe head and are substantially parallel to one another. The ground pin is at a variable distance from the signal pin. The robotic system varies the distance between the ground pin and the signal pin, and positions the ground pin and the signal pin to contact nodes on the circuit board to automate the test.

Why it's free to use
- Filed December 30, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 30, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 30, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
