Need customer inventory PowerShell Example

If anyone would be so kind to please post an example of a custom inventory for 7.1 SP2 using PowerShell.  Specifically, the PowerShell script must return more than one row of data.  I'm clear on how to create a custom inventory which populates the outgoing NSE with one row of data.  For example if a service is running or not.  I'm now moving on to a powershell script that could return 20 or 200 rows.  I just need an example to see how you're setting multiple rows of data.

Thank you
