  • Patent number: 11346656
    Abstract: A device and method and system for utilizing confocal measurement and an optical arrangement to produce 3D color images. A color measurement optical path and a 3D measurement optical path may coincide at least at an object side of the device, and a minimal amount of light is extracted from a monitoring beam for color measurement without affecting 3D measurement.

  • Patent number: 10986328
    Abstract: A device, method and system for utilizing an optical array generator to generate dynamic patterns in a dental camera for projection onto the surface of an object, while reducing noise and increasing data density for three-dimensional (3D) measurement. Projected light patterns are used to generate optical features on the surface of the object to be measured and optical 3D measuring methods which operate according to triangulation principles are used to measure the object.

  • Patent number: 9610867
    Abstract: An infant car seat configured to allow a substantial amount of the car seat's weight to rest on a user's arm is described herein. The car seat generally has an ergonomic handle and a seat shell. The handle includes a handgrip that has a first handle arm and a second handle arm that both extend from the handgrip. In some instances, a first end of the first handle arm and a second end of the second handle arm are rotatably connected to the seat shell. Additionally, while the first handle arm typically comprises a first bowed portion that opens in a first direction and a second bowed portion that opens in a second direction, the second handle arm comprises a third bowed portion that opens in the first direction. In some cases, the car seat also comprises a handhold disposed on a lateral side of the seat shell.

  • Publication number: 20130053837
    Abstract: A system and method are provided for docking a patient interface device to the eye of a patient using suction. The patient interface device is formed by the structural cooperation of a base member and an attachment member, both of which have an open distal end. A contact lens is formed onto the open distal end of the base member, and a continuous abutment is formed onto the open distal end of the attachment member. When the interface device is placed onto the eye of a patient, only the continuous abutment contacts the sclera of the patient. An air pocket is formed between the contact lens and the continuous abutment. The air pocket is in fluid communication with a vacuum channel. A vacuum pump is then employed to suction the air from the air pocket and draw the surface of the eye into contact with the contact lens.

  • Patent number: 6396580
    Abstract: In the procedure, the light beams are incident parallel to the transparent medium and are deflected toward a focal point inside the transparent medium. This avoids the use of refractive lens systems. The focusing lens system according to the invention enables the bundling of light beams of different wavelength to a point inside the sample. This clearly simplifies the design and adjustment of a multicolor fluorescence correlation spectroscopy device.

  • Publication number: 20020045277
    Abstract: Process for qualitative and quantitative detection of an analyte present in a biological sample and in molecular form, in which process a sensor is provided with a substrate binding the analyte and in which in a first process step the sensor is loaded with the analyte and, in a subsequent process step, the total analyte mass bound by the sensor is measured, before in a further step the molecular weight of the analyte forming the total mass is measured.
