A biopsy device includes a first hollow cylindrical element, a second hollow cylindrical element inside which the first hollow cylindrical element is insertable and a locking element that is suitable for locking a tissue sample inside the first hollow cylindrical element. The outlet microprocessor switches the supply of power to the outlet to communicate data to the vehicle. The method further comprises searching an inverted index associated with the database to detect the presence of at least one of the keywords in documents, identified by a document ID, present in the inverted index. Another bitthe fail flag bitis stored in the address register to indicate that a failure has occurred. , so that the overall impedance of the board substantially matches that of one or more of the other circuit boards in a common chassis. The apparatus includes a first electrode, a second electrode and a current generator.
