Abstract: A resonator is suitable for reducing or suppressing a force transmitted by a vibrating portion of the resonator to a support part. To this end, the vibrating portion includes two extensions which are each meander shaped such that two segments of each extension have respective speed components that are oriented in opposite directions. Such a resonator, which is balanced, can advantageously be used within a rate gyro or a force sensor.

Abstract: An inertial angular position sensor includes at least three identical resonators which are arranged symmetrically about a sensitive axis of the sensor, so that a rate gyro constructed from the sensor has an integrating operation. The sensor further includes a coupling element which connects a vibrating portion of each resonator to the vibrating portions of all other resonators of the sensor. Preferred configurations for the inertial angular position sensor allow obtaining integrating rate gyros with high sensitivity and low production cost.

Abstract: Removable barrier devices (e.g., sleeves) for covering medical scanning devices to reduce the chance of cross-contamination between patients and/or to protect the scanning devices from physical damage. The barrier device can include a cover that has an integrated window for passing optical signals between the scanning device and an external environment. The cover can include a sleeve that covers a handle portion of the scanning device to prevent contamination of the handle from a user's hand or glove. The cover and sleeve may both be formed of the same flexible material, or the cover may be rigid to maintain the window in a fixed position and the sleeve may be flexible to allow a user to activate a button or touchpad on the handle. An interface region between the cover and sleeve may provide a hermetic seal. The window may include a nanostructured antireflective material to limit internal reflections.

Abstract: An electrical field detector includes an electromechanical oscillator, part of which is included of a piezoelectric element, a frequency measuring device which is coupled to the oscillator so as to measure the oscillation frequency, and an electrical masking assembly. The electrical masking assembly is arranged close to the piezoelectric element so that, during an use of the detector, the piezoelectric element moves by vibrating relative to the electrical masking assembly. A variable part of the piezoelectric element is thus exposed to the electrical field to be measured. A change in the oscillating frequency then forms an electrical field measurement result.

Abstract: Methods and apparatuses for assessing oral health and automatically providing diagnosis of one or more oral diseases. Described herein are intraoral scanning methods and apparatuses for collecting and analyzing image data and to detect and visualize features within image data that are indicative of oral diseases or conditions, such as gingival inflammation or oral cancer. These methods and apparatuses may be used for identifying and evaluating lesions, redness and inflammation in soft tissue and caries and cracks in the teeth. The methods an include training a machine learning model and using the trained machine learning model to provide a diagnosis of an oral disease or condition based on image data collected using multiple scanning modes of an intraoral scanner.

Abstract: Disclosed is a system and method that provide an amplitude value and a phase delay value which relate to a sinusoidal signal to be measured. For this purpose, phase values of a reference signal, at which the signal to be measured exceeds or falls below the reference signal, are collected and transmitted to a computation unit. The computation unit determines the amplitude and delay values from the collected phase values. The system can be implemented in a cost-effective manner, in particular using an ASIC circuit or an FPGA circuit.

Abstract: An electric measurement circuit possesses an electrical reaction leg for forming an oscillator from a resonator, and furthermore possesses a measurement leg the input of which is supplied by the electrical reaction leg. The measurement leg contains an adjustable phase shifter so that an additional excitation force that is applied to the resonator in the measurement leg can be adjusted in phase quadrature with respect to an excitation force that is applied to the resonator in the electrical reaction leg. Such an electrical measurement circuit is particularly suitable for forming a photoacoustic gas detector.

Abstract: A resonator includes a prong of which the width between edges is close to ?/2. The pressure variation at one edge is then in phase opposition with that at the other edge. Acoustic coupling with an incident wave having the wavelength is thus improved. The ratio between the width between edges and the height of the prong is chosen so that only the fundamental mode with bending oscillation of the prong is present. It to prongs of a tuning fork embedded in a solid shared base optimized to contain the energy in the tuning fork while avoiding energy losses in the support. Finally, the tuning fork is advantageously combined with a unit for containing acoustic energy including a rigid reflecting screen.
