Abstract: A multi-rotor system for providing air thrust is disclosed comprising at least one multi-rotor assembly. The multi-rotor assembly comprising at least two rotors rotatable about a common axis wherein the outer radius of a first rotor is substantially similar to the inner radius of the second rotor. An airborne vehicle is also disclosed that is adapted to perform vertical takeoff and landing (VTOL). The airborne vehicle comprising at least two multi-rotor system disposed substantially symmetrically around the center of gravity of the vehicle.

Abstract: A device for a non-contact measurement of an IOP of a subjects eye including: a frame; a conduit connected to the frame and aligned along a conduit axis; at least one camera connected to the frame and configured to capture one or more image frames each comprising an image of a side view of a cornea of the subjects eye; a fluid pulse generator in fluid communication with the conduit, the fluid pulse generator configured to generate a fluid pulse and puff the fluid pulse through the conduit; and a controller comprising a processing unit, the processing unit configured to: receive the one or more image frames; determine one or more fluid pulse pressure values; and determine the IOP value of the subjects eye based on at least one of the one or more image frames and at least one of the one or more fluid pressure values.

Abstract: In some embodiments, a mobile robot unit for engaging a wheel of parked target vehicle is provided, the mobile robot unit comprising: a frame adjustable from a first configuration to a second configuration and vice versa, wherein in the second configuration the frame engages the vehicle wheel to apply a sufficient counterforce onto the vehicle wheel to lift the vehicle wheel and the vehicle weight supported by the vehicle wheel from the ground; and at least two wheel assemblies supporting the frame above the ground, each wheel assembly comprising at least one steerable wheel, the steerable wheel contacting the ground.

Abstract: A method of non-invasive measurement of an intraocular pressure (IOP), the method may include: obtaining an image of at least a portion of a specific element of a subject's eye; detecting at least a portion of the specific element in the obtained image; and determining a value of a geometric property of the specific element based on the obtained image, the determined value of the geometric property is indicative of an IOP value of the subject's eye. In some embodiments, the specific element comprises at least one of: at least a portion of a limbus and at least a portion of an anterior surface of a sclera of the subject's eye.

Abstract: Methods and orally administered supplements are provided, which use bacterial strains to reduce absorption of calories by a subject from consumed nutrients. The bacterial strain(s) are selected to metabolize at least part of the nutrient(s) consumed by the subject, and may be selected to be excreted and/or to have metabolic products that are excreted by the subject—making some of the consumed calories unavailable to the subject and/or reducing any of a glycemic, a cholesterol/lipids level and a protein value of the consumed nutrient(s). Appropriate coatings or covers may be applied to protect the bacteria from gastric acids, and the specific strains may be adjusted to increase their nutrient metabolism, improve their resistance to intestinal chemical conditions and optimize bacterial communities that may have synergic effects in nutrient metabolism, in a way that makes some of the calories unavailable to the subject.

Abstract: Apparatus and methods are provided including identifying a subject as suffering from a disorder of an organ of the subject. In response to the identifying, a shaft is inserted into the organ, not via a natural lumen of the subject. Using a laser beam emitted from a distal portion of the shaft, a portion of the organ is ablated. A vicinity of the portion of the organ is cooled by introducing a fluid to the vicinity, and, subsequently aspirating the fluid therefrom, the introduction and aspiration of the fluid being performed via the shaft, while the shaft is inside the organ. Other embodiments are also described.

Abstract: A method of long bone strengthening and a composite implant for such strengthening. Also disclosed is a kit for building a composite implant in-situ in long bones. In an exemplary embodiment of the invention, the implant comprises a plurality of rigid tensile rods, in matrix of cement and surrounded by a partially porous bag.

Abstract: This invention concerns an improved multiple biopsy gun to collect tissue samples having a housing and an axially elongated cutting needle and stylet extending from the housing, wherein the housing contains a driving mechanism which propels the stylet and the cutting needle forward in sequential fashion to capture two or more tissue samples, without the necessity to reload the biopsy gun or to remove the biopsy gun from the target site between biopsies.
