Abstract: An ultrasound probe is tested for failure of 5 elements of its array transducer by operating the probe with its lens in contact with the air. The echo signals produced during this mode of operation are beamformed into the usual set of scanlines produced by the probe. The frequency response of 10 each scanline is analyzed and compared with a reference signal of the frequency response of the corresponding scanline of a known good probe of the same type as the probe under test. If a comparison reveals a variance greater than a predetermined 15 deviation, the user is alerted that the probe should be replaced.

Abstract: The present invention relates to a method of securely using a first tenant secret key stored under an encrypted form in a first token (TKA) of a first tenant (A) identified by a first tenant identifier (UIDA) and having said first tenant secret key, wherein: each tenant identifier (UIDT) for a tenant (T) comprises a first value and, when said tenant (T) is allowed to use a secret key of a parent tenant (Tp) identified by a parent tenant identifier (UIDTP), said parent tenant identifier, appended before said first value, and said first token (TKA) has been generated from said first tenant identifier (UIDA) and a first tenant secret key encrypted with said first tenant identifier (UIDA) and with a first tenant customer master key (CMKA), said first tenant customer master key (CMKA) having been derived from said first tenant identifier (UIDA) and a secure domain master key (SDMK), said method comprising the following steps performed by a secure device storing said secure domain master key (SDMK), on request of a

Abstract: The invention relates to a method for activating a terminal (4) by an operator, the activation of the terminal allowing secured exchanges of information between the terminal (4) and a secured server, characterized in that it comprises the following steps for the terminal (4): receiving from the operator (2) a first piece of activation information, receiving from an authorization server (3) a second piece of activation information, using the first and second pieces of activation information for activating the terminal.

Abstract: The putting practice aid mounts on the front face of the putter head and provides a horizontal arm extending in the opposite direction of the intended initial trajectory of the putted golf ball and a second arm perpendicular to the intended trajectory. When these arms are maintained parallel to the putting surface it assures that the golfer has positioned the shaft at the correct angle relative to the putting surface and that the golfer has correctly aimed the club. The putting practice aid may also comprise an observable coating on the surface of the indicator side of the attachment tab which facilitates establishment of a proper angle between the surface of the face of the putter head and the putting surface. The design of the putting aid allows for use with commercially available putters of varying loft and accommodates handedness preferences. The concepts included in the putting practice aid may be directly incorporated into a putter, which itself then becomes a putting training device.

Abstract: Hard magnetic core particles for use in the development of electrostatic latent images are produced by combining ferric oxide, a strontium oxide precursor, an oxygenated boron compound and a binder to form a mixture, wherein the strontium oxide precursor is preferably present in an amount that provides SrO in a molar amount that is in excess of a stoichiometric amount that provides a ratio of Fe2O3 to SrO of 6/1. The mixture can be formed into green beads and the green beads can be fired to form the hard magnetic core particles.
