摘要： A direct view display system (DVDS) and a method to operate it are provided herein. The DVDS may include: a variable optical power element (VOPE); a transparent active image source located with the VOPE on a common optical axis going from an outside scene to an eye position of a viewer; and a time division multiplexer (TDM) configured to control the VOPE and the transparent active image source, wherein the TDM is configured in a certain time period to cause the transparent active image source to be in a transparent state and the VOPE to exhibit no optical power, and wherein the TDM is configured in another time period to cause said transparent active image source to exhibit an image and said VOPE to apply non-zero optical power, for projecting the image onto the eye position at a desirable distance therefrom.

摘要： A system and a method of monitoring physical properties of a physical medium over time are provided herein. The method may include the following steps: embedding a plurality of acoustic sensors into a physical medium before curing thereof; transmitting an acoustic wave by at least one transmitter coupled to or embedded within said physical medium; repeatedly calculating, over different points of time, a travel time of said acoustic wave between the at least one transmitter and the plurality of acoustic sensors; and analyzing said travel times, to detect a change over time in physical properties of said physical medium associated with said travel time.

摘要： An autonomous navigation system and method for a maneuverable platform are provided herein. The method may include: obtaining a plurality of objectives relating to a maneuverable platform; determining a plurality of options of direction and speed for the platform; autonomously selecting, one option of the plurality of options, in order to achieve said objectives, by calculating a weighted grade of each option based on the weights of the objectives and said grading scheme; and periodically repeating: the receiving with updated platform and obstacles data and the autonomously selecting with the updated platform and obstacles data, wherein the autonomously selecting is executed by a computer processor and includes, for each obstacle, calculating projected positions of the platform and of that obstacle to determine the distance between the platform and the obstacle at the closest point of approach and estimated time to arrive to the closest point of approach.

摘要： A map data structure and method and system for obtaining geographic information. Raw map data is converted into map data structure by generating an attribute layer for each geographic attribute according to a defined line pattern and line width, and defining a bit-array of fixed bit-length for each element of a grid representing geographic coordinates, where a bit value of “1” is assigned if a respective attribute is present at the grid element location and a bit value of “0” is assigned if the respective attribute is absent. A map image depicting selected geographic attributes may be generated and displayed from map data structure, by sequentially scanning each bit in bit-array in descending order of priority, for each grid element of selected location, and if binary value of scanned bit is “1” then attribute layer associated with bit is displayed according to assigned color value if attribute selected for display.

摘要： Head mounted displays (HMD) and corresponding display methods are provided, which obtain, repeatedly, from a monitoring system of a vehicle and, a reference vector relating to the vehicle; display on the HMD a reference symbol that indicates the reference vector; and determine movements of a HMD symbology according to a spatial relation between a received user's line of sight (LOS) and the reference vector. For example, the vehicle may be an aircraft and the reference vector a flight path vector (FPV) received from the aircraft's avionics. The proposed HMD enhances the displayed information content while avoiding excessive movements of the symbology. The HMD's functional parameters may be pre-set or adapted according to user preference and flight stage characteristics. The reference symbol anchors most of the symbology, while minimal critical information may be moved along with the user's LOS, providing a clearer and more stable view through the HMD.

摘要： An active, transparency-controlled window comprises at least one layer of a material that is transparent to at least selected wavelengths of light; at least one layer of photochromic material having a transparency, to the at least selected wavelengths of light, that can be controllably altered by an activating light; and a controllable source of light that activates the photochromic material to controllably alter the transparency of the photochromic material to the at least selected wavelengths of light. The material that is transparent to at least selected wavelengths of light may be a material selected from the group consisting of glass and plastic.

摘要： Aircraft system and method detecting and present information relating to adverse airborne phenomena along an aircraft flight route. An imaging unit that includes an IR detector and a tunable spectral filter acquires IR images of the external environment, by acquiring wideband IR images when operating in a first mode and narrowband IR images respective of difference IR spectral bands when operating in a second mode. A data analysis unit detects and determines characteristics of adverse airborne phenomena in the environment based on at least the spectral signatures of environmental features in the acquired narrowband IR images. A display unit dynamically displays a visual representation of the detected adverse airborne phenomenon and its determined characteristics, overlaid onto a view of the external environment displayed to an operator of the aircraft. The visual representation may include variable visual attributes representing respective categories of characteristics of the detected adverse airborne phenomenon.

摘要： Systems and methods are provided, for managing the attention of a user attending a display and for managing displayed information in control centers. Methods and systems may identify, from displayed data, a piece of information, locate a display position of the identified piece of information, and display the visual cue at a specified interval prior to displaying the piece of information, at a cue position on the display that has a specified spatial relation to the display position of the piece of information. Methods and systems may further quantify an attention pattern of a user, relate it to recorded reaction times of the user to the displayed data, and modify spatio-temporal parameters of the visual cues to decrease the user's reaction times according to specified requirements. Specific data may be enhanced according to user performance and various definitions.
