Insert pockets of tool holders configured to accommodate multiple differently-shaped cutting inserts are disclosed. The method for testing a PCIE expansion system comprises delivering the data signals from the data lanes to a compliance board that is configured to loop back at least a first portion of the data signals and transmit a complementary second portion of the data signals to a testing device, and testing a compliance of the second portion of the data signals with the PCIE requirements. The system further comprises an antenna, and the detection system includes a proximity sensing signal generator arranged to generate a proximity sensing signal to be transmitted between the antenna and the first layer via a user of the system. If the surface falls into one sub-region only, the data is sent to one rendering device only. The pattern transfer is similarly carried out for the divided area. The process can be used to generate periodic progress reports and management status reports based on the steps completed on each checklist.
