  • Publication number: 20240076761
    Abstract: Described herein are technologies for bauxite or kaolin mining operations. A detector is used to detect the presence of a pathfinder element or radioactivity indicating a presence of a rare-earth element. Once the pathfinder element or radioactivity is detected, the mined material is segregated from material mined in which a pathfinder element or radioactivity was not detected. Rare-earth elements are extracted from the segregated material. Once the rare-earth elements are extracted, the material is returned to normal mining operation processing steps.

  • Patent number: 11850093
    Abstract: In one embodiment of the invention, a robotic surgical system includes a combined laser imaging robotic surgical tool, a control console, and a laser generator/controller. The tool is mounted to a first robotic arm of a patient side cart. The tool has a wristed joint and an end effector coupled together. The end effector has a laser-emitting device to direct a laser beam onto tissue in a surgical site and an image-capturing device to capture images of the tissue in the surgical site. The control console, in communication with the tool, receives the captured images of tissue in the surgical site and displays the captured images on a display device to a user. The laser generator/controller is coupled to the tool and the control console to control the emission of the laser beam onto tissue of the surgical site.

  • Publication number: 20230333364
    Abstract: The invention relates to an optical system (7) having an optical axis (OA), having a display unit (5) for displaying an image, having an eyepiece (6) for viewing the image, the eyepiece (6) comprising a lens unit (L1). The display unit (5) is designed in such away that a marginal ray light beam (9) emanates from an edge (8) of the display unit (5) and propagates to the lens unit (L1) in a light incidence direction (L). The display unit (5) is arranged first along the optical axis (OA) in the light incidence direction (L), followed by the lens unit (L1) arranged on the optical axis (OA). No further optical unit of the optical system (7) is arranged between the lens unit (L1) and a pupil of the eye (2). The marginal ray light beam (9) has a chief ray (HS). The chief ray (HS) propagates at a first chief ray height (H1) at the lens unit (L1) and at a second chief ray height (H2) at the display unit (5). The first chief ray height (H1) is at least level with the second chief ray height (H2).

  • Patent number: 11667971
    Abstract: Probe systems and methods are provided for detecting nucleic acid targets using labeled polynucleotide probes and antiprobes that interact together and with complementary targets. These interactions result in signaling changes that indicate target frequency and provide error-checking functions that facilitate single base discrimination. These probe:antiprobe compositions enable real-time PCR detection, end-point detection and microarray detection of microbial species, drug resistant mutants, and cancer related variants. The probe:antiprobe may be an internal probe between two primers or may be a primer-probe. The probe also may be modified by introducing a base mismatch to increase thermodynamic discrimination of a correct versus incorrect target differing by a single base. Probe systems also are provided for use in methods of increasing target amplification and detecting specific single base variants.

  • Patent number: 10073256
    Abstract: An apparatus for imaging a sample arranged in a first medium in an object plane. The apparatus includes an optical transmission system which images the sample in the object plane in an intermediate image in an intermediate image plane. The object plane and the intermediate image plane form an angle not equal to 90° with an optical axis of the transmission system. The apparatus further comprises an optical imaging system having an objective. The object plane may be imaged on a detector without distortion. The optical transmission system is symmetrical with respect to a pupil plane, the object plane, and the intermediate image plane to satisfy the Scheimpflug condition. The intermediate image lies in a second medium having a refractive index virtually identical to that of the first medium. A lens group of a subsystem arranged closest to the sample or intermediate image comprises at least one catadioptric assembly.
