Thermal Testing Of A Nonthermal Quantity Patents (Class 374/45)
  • Patent number: 10801933
    Abstract: The present invention provides a self-healing method for fractured SiC amorphous nanowires. A goat hair in a Chinese brush pen of goat hair moves and transfers single crystal nanowires under an optical microscope. On an in-situ nanomechanical test system of a TEM, local single crystal nanowires are irradiated with an electron beam for conducting amorphization transformation. Amorphous length of a single crystal after transformation is 60-100 nm. A fracture strength test is conducted on the amorphous nanowires in the single crystal after transformation in the TEM; and fracture strength of the amorphous nanowires is 9-11 GPa. After the amorphous nanowires are fractured, unloading causes a slight contact between the fractured end surfaces; and self-healing of the nanowires is conducted after waiting for 16-25 min in a vacuum chamber of the TEM. Atom diffusion is found at a healed fracture through in-situ TEM representation; and recrystallization is found in the amorphous nanowires.

  • Patent number: 10761607
    Abstract: In one implementation, a multi-mode haptic effects delivery system includes an impact surface, a mass adjacent to the impact surface, and a driving mechanism configured to reciprocate the mass. The multi-mode haptic effects delivery system also includes a motor configured to generate a vibrational mode haptic effect. The driving mechanism configured to reciprocate the mass causes the mass to strike the impact surface so as to generate a recoil mode haptic effect. In one implementation, the driving mechanism is a gear assembly powered by the same motor used to generate the vibrational mode haptic effect.

  • Patent number: 10656081
    Abstract: A method and system for detecting moisture in a composite sandwich panel for an aerospace vehicle. A pulse of an electromagnetic radiation beam is beam steered to the composite sandwich panel. The pulse of the electromagnetic radiation beam has a number of wavelengths that is absorbed by water molecules. The timing of the pulse of the electromagnetic radiation beam is synchronized to heat the composite sandwich panel with a time window in an infrared detector system to detect an amount of infrared radiation. The amount of infrared radiation in the composite sandwich panel is detected within the time window for the infrared detector system when the composite sandwich panel is heated by the pulse of the electromagnetic radiation beam, wherein the amount of infrared radiation indicates a level of moisture in the composite sandwich panel.

    Abstract: Devices, systems, and techniques for monitoring the temperature of a device used to charge a rechargeable power source are disclosed. Implantable medical devices may include a rechargeable power source that can be transcutaneously charged. The temperature of an external charging device and/or an implantable medical device may be monitored to control the temperature exposure to patient tissue during a charging session used to recharge the rechargeable power source. In one example, a temperature sensor may sense a temperature of an internal portion of a device, wherein the housing of the device is not directly thermally coupled to the temperature sensor. A temperature for the housing of the device may then be estimated based on the sensed temperature provided by the non-thermally coupled temperature sensor. A processor may then control charging of the rechargeable power source based on the determined temperature for the housing.

  • Patent number: 9791395
    Abstract: The present disclosure provides a method for detecting thermal sealing defects of a container during its transportation along a process line. The method is particularly suitable for containers caped with a cap liner and sealed with an inner seal. The method makes use of a high frequency heat (e.g. by a high frequency heat induction unit) to cause eddy current in the inner seal after which there is sensing by an IR imager of radiation emitted from the conductive innerseal to generate sensed IR image data indicative of the sensed radiation. The sensing is characterized by at least one of (i) a time window of a sensing session of between 50 msec to 300 msec during which said container is being transported through the FOV; and (ii) a sensing range of a wavelength spectrum region from 2 ?m to 6 ?m. The IR data is then processed so as to generate output data indicative of the presence or absence of at least one defect in the sealing of the container by said innerseal.

  • Patent number: 9607649
    Abstract: A test involves iterations over a series of laser powers of a heat-assisted read/write head. The iterations involve writing to a recording medium at the selected laser power for a sufficient duration to ensure thermal equilibrium of the read/write head at an end of the write. A clearance-control heater of the read/write head is transitioned from a pre-write power before a start of the write to a steady-state write power. The iterations further involve measuring a temperature of the read/write head during the write and adjusting the steady-state write power to achieve a predefined difference between the temperature at the start of the write and the end of the write. The adjusted steady state write power is stored for each iteration. A write-induced protrusion is determined based on the iterations and used for calibration of the read/write head.

  • Patent number: 9582865
    Abstract: Blood flow beneath a user's skin, for example, in a user's face may be visually rendered. In some aspects, a plurality of differences is determined in the intensity of pixels of a first image and the corresponding pixels of a subsequent second image. In some aspects, this plurality of differences is enhanced to accentuate a characteristic associated with the first image and the second image. The enhanced plurality of differences is visually rendered for each subsequent comparison of pixel intensity values.

  • Patent number: 9470605
    Abstract: An airfoil has an of internal cooling channel, and cooling holes extending from the internal cooling channel to an outer skin. Air is injected into the cooling channel, and then into an inlet of the cooling hole. The exit of the air from an outlet of the cooling hole at the outer skin is monitored to determine whether the outlet is blocked. A location of the inlet of the cooling hole is determined by utilizing the determined location of the outlet, in combination with a known angle through which the cooling hole extends.

  • Patent number: 9176012
    Abstract: Methods and devices for improved membrane-based microcalorimeters are disclosed. The sample mixing speed or “temporal addenda” of the calorimeter can be improved using membranes with patterned hydrophilic and hydrophobic regions, oscillating droplet squeezing methods, and textured membrane surfaces with ridges designed to facilitate rapid mixing. The thermal coupling between the membranes and the other calorimetric addenda can be minimized by exposing the back side of the calorimetric membrane to a vacuum, while keeping the front side exposed to a humidified environmental chamber. Specially shaped, membrane associated heat-transfer-elements can help the system accurately monitor substantial portions of the sample. These elements, in conjunction with the position of the edge of the sample, can be designed to minimize inaccuracy due to edge evaporation effects.
