  • Patent number: 11589929
    Abstract: The invention relates to an assessing device (13) for assessing the suitability of a shape of an instrument like a guidewire for a registration of a position and shape determination device (10) like an optical shape sensing device with an imaging device (2). Curvature values being indicative of the curvature at several positions along the instrument are determined, which are used for determining shape feature values. These shape feature values are then used for determining a suitability value being indicative of the suitability of the shape of the instrument for the registration procedure, wherein an output is provided to a user based on the determined suitability value. The user can therefore modify the shape until the output indicates that the shape of the instrument is suitable for the registration, without requiring any image. This can reduce a radiation dose if the image is, for instance, an x-ray image.

    Abstract: An optomechanical pressure-measurement system measures pressure in the range of 10?6 Pa-10?2 Pa by measuring various properties of a vibrational mode of an ultra-thin membrane member. With independent measurements of the thickness and density of the membrane, in addition to the measured vibration mode properties, the system can operate as a primary pressure sensor. The membrane member is mounted on a vibration-isolated mount and is excited by a drive force. A laser beam impinges on the excited membrane, and an optical phase detector detects the amplitude of the oscillations, as well as parameters of the laser beam affected by the membrane vibration. In one embodiment, a mechanical damping is computed based on the amplitude or frequency shift (depending on the pressure range), and the pressure based on the ring-down time of the membrane vibration mode.

  • Patent number: 10600209
    Abstract: A calibration method for a camera which monitors a target board is disclosed, comprising steps: using the camera to capture a target image corresponding to the target board; using rotation and translation to align the target image to a reference standard and acquire the corresponding relationship of the target image and the target board; defining a region of interest above the target image; using at least one positioning marker in at least two positions of the target board, whose actual space coordinates are known, and using the camera to acquire at least two image coordinates of the positioning markers in the region of interest; and using the known actual space coordinates and the acquired image coordinates to work out the exact position of the camera. Thereby, the positions of the cameras can be used to correctly determine the positions of darts.

  • Patent number: 10516686
    Abstract: A system for malware and anomaly detection via activity recognition based on sensor is disclosed. The system may analyze sensor data collected during a selected time period from one or more sensors that are associated with a device. Once the sensor data is analyzed, the system may determine a context of the device when the device is in a connected state. The system may determine the context of the device based on the sensor data collected during the selected time period. The system may also determine if traffic received or transmitted by the device during the connected state is in a white list. Furthermore, the system may transmit an alert if the traffic is determined to not be in the white list or if the context determined for the device indicates that the context does not correlate with the traffic.

  • Patent number: 10495844
    Abstract: Provided is a lens drive device that, using drive force from a voice coil motor, automatically carries out focusing by moving an autofocus movable unit with respect to an autofocus fixed unit in the direction of an optical axis. The lens drive unit is provided with a position detection unit that is disposed with an intervening space on the image formation side of the autofocus movable unit in the direction of the optical axis and that is for emitting light toward the autofocus movable unit, receiving reflected light that has been reflected by the autofocus movable unit, and detecting the position of the autofocus movable unit in the direction of the optical axis on the basis of the received light intensity. Part of the member displaced along with the autofocus movable unit functions as a reflective plate for reflecting light emitted from the position detection unit.

  • Patent number: 10432194
    Abstract: A method of operating a sensor system having at least one proximity sensor, with regard to generating a trigger signal indicative of an occurrence of an operator-intended event in the presence of noise. The method includes repetitive steps of: acquiring the sensor signal at specified sampling times, comparing a value obtained as a presently sampled sensor signal with a presently valid first threshold value, generating a trigger signal if the value obtained as the presently sampled sensor signal is as large as or exceeds the presently valid first threshold value, omitting to generate a trigger signal if the value obtained as the presently sampled sensor signal is less than or equal to the presently valid first threshold value, forming a subset out of the sampled sensor signals, determining an update value for the first threshold value, and replacing the presently valid first threshold value by the update value.

  • Patent number: 10411646
    Abstract: A method for inspecting a solar cell and configured to inspect a peeling state of a three-dimensional pattern of the solar cell includes obliquely illuminating the three-dimensional pattern of the solar cell using a light beam. An image of the solar cell is normally captured. An intensity of the light beam is increased to increase a contrast between the three-dimensional pattern and a shadow of the three-dimensional pattern in the image and increase a contrast between an ink pattern of the solar cell and the shadow in the image to overexpose the ink pattern in the image. Determine if the three-dimensional pattern is peeling according to the shadow of the three-dimensional pattern in the image.
