Abstract: A system, apparatus and method, the system comprising: a scanning device for obtaining information about a cavity, the scanning device comprising a localization and mapping device and adapted to register a first location relative to the cavity after the system is stationary for some time, said registration associated with a first time stamp; a device for providing location information; a processor for obtaining an absolute location of the system from the device for providing location information when the system is stationary for the time; and registering the absolute location in association with a second time stamp; a second processor for generating a model of the cavity based on the information from the scanning device; and matching the absolute location with the location, based on the time stamps; and a display device for displaying a representation of the model, comprising an indication the first location with the associated absolute location.

Abstract: A system, apparatus and method, the system comprising: a scanning device for obtaining three dimensional (3D) information about a cavity surrounding a user, the scanning device comprising a localization and mapping device and an inertial measurement unit; an image capture device for capturing images within the cavity; a processor for receiving the information collected by the scanning device and generating a model of the cavity based on the information; and a display device adapted to display to the user a representation of the model of the cavity, and a route taken by the user within the cavity, wherein the scanning device and the display device are adapted to be attached to at least one wearable item, thereby enabling the user to advance with free hands within the cavity.

Abstract: A net and method for creating the same, the net comprising: cables in two or more directions, wherein the cables in each of the directions are made of at least a first construct or a second construct, wherein each cable of a first construct in the first direction has neighboring cables in the first direction made of the second construct, and each cable of the first construct in the second direction has neighboring cables in the second direction made of the second construct.

Abstract: Devices for accumulating material within a limited space, such that at most insignificant amount of material leaves the device prior to the device being at full capacity. One embodiment comprises an expandable structure to be filled, comprising a material receiving member for receiving expansible material, such that the expansible material is inserted into the member and expands within the member prior to part of the material exiting the material receiving member into another member, wherein the expansible material expands and rigidizes within the material receiving member and within the another member to form a rigid structure having a required form.
