Drum tuning as compared to tuning most musical instruments does not involve detecting simple series of harmonically related notes (same note in different octaves), but different unrelated notes generated by the sundry different length physical paths that different head resonances travel over. 060 claim 1 with several means combined describes applying a ...

Non-Cited Prior Art Found I find it amusing that Jesse Aronstein was mentioned via patent US4741242 in the asserted US8502060 patent, yet Aronstein's US4457203 was not. I know that all inventors get a bug in them and never stop inventing. I know if you've ever had a patent, you want more. Why would you cite someone in your patent and not do your full ...

Unfortunately the 20100212475 by Toulson is listed on the face of the 8502060 patent. AFAIK that means that there is a presumption (albeit rebuttable) that this document was reviewed by the Patent Examiner and that the CLAIMS of the 8502060 application were nonetheless patentably novel and nonobvious over the Toulson reference.* In a normal 3rd party ex ...

My understanding of guitar tuners from Zen-on Justina Quartz Guitar Tuners and many other tuners utilize a filter means when you select which guitar string you are tuning to.
