Delaying sensor signal for PC io card

I have an application that needs to detect a sensor signal.
The bad part is, the signal is too fast for the pc to detect.
Currently I am using a PIC to collect the signal from the sensor then delay the pulse so that the pulse is slow enuf for the pc to capture by using io card.
I am just wondering if there is any other way of doing this besides using PIC?

Thanks in advance.

Use a monostable to stretch the pulse

A more complicated but more elegant way is to have the sensor set a flip flop, which the PIC will reset once it has been read.
