  • Patent number: 10886420
    Abstract: The wafer-level manufacturing method makes possible to manufacture ultrathin optical devices such as opto-electronic modules. A clear encapsulation is applied to an initial wafer including active optical components and a wafer-size substrate. Thereon, a photostructurable spectral filter layer is produced which defines apertures. Then, trenches are produced which extend through the clear encapsulation and establish sidewalls of intermediate products. Then, an opaque encapsulation is applied to the intermediate products, thus filling the trenches and producing aperture stops. Cutting through the opaque encapsulation material present in the trenches, singulated optical modules are produced, wherein side walls of the intermediate products are covered by the opaque encapsulation material. The wafer-size substrate can be attached to a rigid carrier wafer during most process steps.

  • Patent number: 10881751
    Abstract: Ultraviolet irradiation of food handling instruments for purposes of sterilization, disinfection, cleaning and other treatment capabilities. A housing having receptacles receives one or more food handling instruments. Ultraviolet light emitting sources located about the receptacles can direct ultraviolet light towards the receptacles and any food handling instruments placed therein. One or more sensors located about the receptacles can detect operational conditions associated with the receptacles and any food handling instruments received therein. A control unit, operatively coupled to the ultraviolet light emitting sources and the one or more sensors, manages the irradiation of the receptacles and any food handling instruments in the receptacles as a function of the operational conditions detected by the one or more sensors.

  • Publication number: 20200405157
    Abstract: An apparatus, system, and method for monitoring a person suffering from a chronic medical condition predicts and assesses physiological changes which could affect the care of that subject. Examples of such chronic diseases include (but are not limited to) heart failure, chronic obstructive pulmonary disease, asthma, and diabetes. Monitoring includes measurements of respiratory movements, which can then be analyzed for evidence of changes in respiratory rate, or for events such as hypopneas, apneas and periodic breathing. Monitoring may be augmented by the measurement of nocturnal heart rate in conjunction with respiratory monitoring. Additional physiological measurements can also be taken such as subjective symptom data, blood pressure, blood oxygen levels, and various molecular markers. Embodiments for detection of respiratory patterns and heart rate are disclosed, together with exemplar implementations of decision processes based on these measurements.

  • Patent number: 10876915
    Abstract: Improvements in thin film sensors are disclosed. These can be used for aircraft applications. Dielectric isolation washers can be provided between a pressure sensor and an exterior metal housing of a sensor assembly. In this manner, high voltage inputs from a lightning strike or other source that reach the sensor housing are not transmitted to the sensor. Dielectric washers, insulators, and potting compounds can thus isolate a metal thin film pressure sensor from adjacent metal components (e.g., using non-conducting insulating materials like Torlon, zirconia and nylon). Besides their high dielectric strength, these materials exhibit compressive strength and resistance to wear, creep and corrosion. Desirable thicknesses for these components are provided. The described thin film pressure sensor embodiments can attain a dielectric rating of 1500 VAC.

  • Patent number: 10869943
    Abstract: An approach for treating a fluid transport conduit with ultraviolet radiation is disclosed. A light guiding unit, operatively coupled to a set of ultraviolet radiation sources, encloses the fluid transport conduit. The light guiding unit directs ultraviolet radiation emitted from the ultraviolet radiation sources to ultraviolet transparent sections on an outer surface of the fluid transport conduit. The emitted ultraviolet radiation passes through the ultraviolet transparent sections, penetrates the fluid transport conduit and irradiates the internal walls. A control unit adjusts a set of operating parameters of the ultraviolet radiation sources as a function of the removal of contaminants from the internal walls of the fluid transport conduit.

  • Publication number: 20200393542
    Abstract: Radio frequency motion sensors may be configured for operation in a common vicinity so as to reduce interference. In some versions, interference may be reduced by timing and/or frequency synchronization. In some versions, a master radio frequency motion sensor may transmit a first radio frequency (RF) signal. A slave radio frequency motion sensor may determine a second radio frequency signal which minimizes interference with the first RF frequency. In some versions, interference may be reduced with additional transmission adjustments such as pulse width reduction or frequency and/or timing dithering differences. In some versions, apparatus may be configured with multiple sensors in a configuration to emit the radio frequency signals in different directions to mitigate interference between emitted pulses from the radio frequency motion sensors.

  • Patent number: 10867374
    Abstract: A method of focusing an imaging device includes acquiring an image. A determination is made whether contrast difference between a pixel and one or more adjacent pixels is likely due to noise, or whether the contrast difference is due to the image being out-of-focus. Focus of the imaging device is when the contrast difference is due to the image being out-of-focus while contrast difference determined to likely be due to noise is ignored.

  • Patent number: 10858643
    Abstract: An approach for preparing a vaccine using ultraviolet radiation is described. Aspects of this approach involve multiple iterations of inactivation of the vaccine using an ultraviolet radiation source at a set of different wavelengths and dosages. A recognition test of the vaccine using the set of different wavelengths and dosages is performed after the multiple iterations of inactivation. A controller compares results from the inactivation test and the recognition test to determine an area of acceptable radiation dosages and wavelengths generated from the ultraviolet radiation source that irradiate the live organisms without affecting efficacy and safety of the vaccine. The area of acceptable ultraviolet radiation dosages and wavelengths is representative of a difference between an ultraviolet radiation dosage that is required for inactivation and an ultraviolet radiation dosage that leads to a loss of recognition.
