  • Patent number: 11454561
    Abstract: Contact-force-sensing systems that can provide additional information about the forces that are applied by catheters and other devices to cell walls and other surfaces. One example can provide directional information for a contact-force-sensing system. For example, magnitude, plane angle, and off-plane angle information can be provided by a contact-force-sensing system. Another example can provide guiding functionality for a contact-force-sensing system. For example, a contact-force-sensing system can provide tactile response to a surgeon or operator to allow a device to be accurately guided though a body.

  • Patent number: 11428599
    Abstract: A method and apparatus for checking an enclosure for leaks. An ultrasonic signal generator on one side of the enclosure emits ultrasonic signals. An array of ultrasonic transducers on the other side of the enclosure received ultrasonic signals from the signal generator through a leak and produces an acoustic image. An optical camera generates an optical image that may be combined with the acoustic image to display the location of a leak in the enclosure. An estimate of the leak size may be calculated and displayed together with the acoustic image.

  • Patent number: 11415417
    Abstract: A cavity optomechanical vibratory gyroscope pertains to technical fields of resonant optical gyroscopes and micro-optical-electro-mechanical systems. A novel cavity optomechnical Coriolis vibratory micro gyroscope is realized based on ring micro rings and the Coriolis vibration principle, and driving and detection thereof is completely different from conventional electric or magnetic means. Based on the principle of angular velocity sensitive structures in the conventional Coriolis vibratory gyroscopes, full-optical driving, detecting and sensing of a vibratory gyroscope are achieved using cavity optomechnical technologies, which fundamentally suppresses various noises (including thermal noise, cross interference, connection point noise and quadrature error) introduced by electric or magnetic driving. Besides, displacement (vibration) sensing information is obtained according to a linear relationship between frequency shift and light amplitude in the micro cavity optomechnical effect.

  • Patent number: 11406290
    Abstract: Systems and methods for monitoring a range of motion of a joint are described. For example, in one embodiment, a first set of sensors may sense accelerations of a first body portion located on a first side of the joint and a second set of sensors may sense accelerations of the second body portion located on a second opposing side of the joint. The acceleration data may then be used to compute the relative motion of the first and second body portions to determine movement of the joint. This joint movement may then be used to determine one or more range of motion movement metrics which are output for viewing by a subject or medical practitioner.

  • Patent number: 11394042
    Abstract: A fuel cell system includes a fuel cell stack, a gas liquid separator, a water level sensor, a drain valve, and a control unit. When a failure detection processing method is performed, a control unit makes a determination of main conditions where the water level sensor determines that water is present, a power generation current value of the fuel cell stack is not more than a predetermined current threshold value, a drain valve for discharging water in the gas liquid separator is open. Then, the control unit counts elapsed time when the main conditions are satisfied, and in the case where the main conditions are kept satisfied for the elapsed time which is larger than a time threshold value, the control unit determines that the water level sensor has a failure.

  • Patent number: 11353353
    Abstract: The present invention relates to a method and apparatus (5) for determining a change in volume within a vessel (11) with regard to fluid (14) being added or removed from the vessel. The method involves measuring first and second surface levels (20, 20?) of fluid (14) within the vessel (11) (with regard to fluid being added or removed therefrom), first and second roll values (23, 23?) of the vessel, and first and second pitch values (26, 26?) of the vessel. From these measurements, and in conjunction with the known interior dimensions and known interior total volume of the vessel, there are calculated first and second fluid volumes that are compared to determine a change in fluid within the vessel.

  • Patent number: 11340131
    Abstract: Systems, methods, and apparatuses for taking pressure measurements are provided. A multi-hole pressure sensor probe can include a probe tip having a plurality of probe tip holes. The probe tip holes can lead to probe tip channels that convey fluid from the measurement environment to pressure transducers. The pressure transducers can operate using optical transduction techniques. A light source can be applied to the diaphragm, and the light reflected from the diaphragm changes as the position of the diaphragm changes. Further, a reflective material can be applied on the backside of the diaphragm to increase its reflective properties. The light can then be collected and analyzed using a photodiode to determine the environmental pressure acting on the different holes of the probe.
