Abstract: The disclosure provides systems and methods for data analysis of experimental data. The analysis can include reference data that are not directly generated from the present experiment, which reference data may be values of the experimental parameters that were either provided by a user, computed by the system with input from a user, or computed by the system without using any input from a user. Another example of such reference data may be information about the instrument, such as the calibration method of the instrument.

Abstract: For anchoring a mat to the carpet of an automobile against forward movement, a clip for engaging the mat at its rearward edge is operated by a protector plate which shields the clip from impact while also serving to operate the jaws between an open and a closed position. The clip is linked to a hook so as to permit independent lateral and longitudinal movement by the clip with respect to the hook. The hook has a forward facing pin portion for engaging the automobile carpet and an anchoring stud portion extending substantially perpendicularly to said pin portion also for engaging said carpet and resisting the accidental removal of the pin. The hook is made of a springy material and is so shaped as to cause the carpet to be pinched between the pin portion and another part of the hook, thereby providing additional resistance to the withdrawal of the pin from the carpet.
