Abstract: A method and apparatus for determining a thickness of an object using ultrasonic signals are disclosed. The method includes the steps of transmitting ultrasonic signals toward the object, digitizing a reflected echo sequence of the ultrasonic signals, including interpolating the echo sequence, and processing the echo sequence by detecting maximum amplitude peaks in the echo sequence and determining the object thickness based on a time duration between the maximum amplitude peaks.

Abstract: The invention relates to a method for processing an ultrasonic analog signal (10) representing a reflected ultrasonic wave, wherein the ultrasonic analog signal (10) is fed in a parallel manner into at least two signal paths (A;B) and the ultrasonic analog signal is supplied in each signal path (A;B) to respective amplifiers (20A;20B) whose gains are different from one another. The ultrasonic analog signals (11;11?) which have thus been amplified differently are supplied in each signal path (A;B) to a respective A/D converter (30A;30B) which converts the amplified ultrasonic analog signals (11; 11?) into digital ultrasonic data (12;12?), from which a combined digital ultrasonic signal (15) is reconstructed after further processing steps. According to the invention, a decomposition of the digital ultrasonic data (12; 12?) is carried out in each signal path (A;B) by the first level of a wavelet filter algorithm, and the wavelet coefficients are altered by a threshold analysis.

Abstract: The invention relates to a method for processing signals which are generated by the reflection of ultrasonic waves by defects in the surface of objects during the non-destructive testing of objects such as pipes, bars, sheet metal, or uniform and complex carbon-fiber components. Said method comprises the following steps: emission of a complete wavefront onto at least one test section of the object, using a plurality of independent emission elements; receiving a wave reflected by the structure of the object by means of a plurality of receiver elements that are independent of one another; digitalization of the signals received by the receiver elements in digitizing steps; continuous modification of delay values and/or the number of receiver elements for each digitalization step (on-the-fly).

Abstract: An oral care implement package is described herein. The oral care implement package can have a backer with a vapor impermeable layer attached thereto. The backer is attached to a plastic shell. An oral care implement having a scented tongue cleaner and/or a scented handle is positioned between the plastic shell and the vapor impermeable layer. The vapor impermeable layer reducing the amount of scent released from the tongue cleaner and/or handle while the oral care implement is in the package.

Abstract: A method for coating a cleaning region of an interdental cleaning device, which includes preheating the cleaning region to a predetermined temperature. Then, immersing the preheated cleaning region in a coating agent. The coating agent including a flavoring agent encapsulated in a wax, thereby forming a coating on the cleaning region upon immersion. Next, a flow of air is forced across the coated cleaning region in a drip zone, thereby removing an excess portion of the wax and exposing at least a portion of the flavoring agent at a surface of the coating. Then, the coating is cured by cooling the cleaning region.

Abstract: A method and a device for testing a structural component having a complex surface contour utilizing ultrasound, at least one ultrasonic head (UPK) being guided along the surface contour (OK) of the structural component (BT) by means of a manipulator (MM) having several axial drives (MX, MJ, MZ, MA, MB) in several axes at a defined spacing (A) along the surface contour (OK) of the structural component (BT). To also ensure a high measuring accuracy in structural components which have a complex curved surface contour, the axial drives (MX, MJ, MZ, MA, MB) of the manipulator (MM) are synchronously moved along predetermined support points, a trigger drive (MRT) is controlled in synchronism with the axial drives (MX, MJ, MZ, MA, MB) and moved together with all engaged axial drives according to a predetermined surface line (OL) reproducing the surface contour (OK) and the trigger drive (MRT) generates equidistant trigger pulses relative to the surface line (OL) of the complex surface contour.

Abstract: A handheld toothbrush with a brush head having a forward free end and a rearward portion. Provided at the forward free end of the brush head is at least one bristle tuft of a first set. Adjoining the first set in rearward direction is a second set of tufts comprised of several bristle tufts arranged serially on a ring and extending in the circumferential direction of the ring at an angle of inclination relative to the surface of the brush head. A third set of tufts adjoins the second set of bristle tufts in the direction towards the rearward portion. The tufts of the third set are inclined in the circumferential direction in opposition to the direction of the bristle tufts of the second set. As a result, these tufts are capable of penetrating optimally between the user's teeth, hence ensuring a better cleaning result.
