Abstract:
A method for visualizing motion in a video image, comprising the steps of: consecutively reading (201) source frames of the video image; for each source frame, generating (202) a moving object mask, the moving object mask indicating objects which changed position between the frame and at least one past frame; combining (203) a source frame with at least one moving object mask generated for at least one past source frame (P1, P2) and at least one future frame (F1, F2) to generate a combined frame.
Abstract:
A system for detecting acoustic features of a loudspeaker system in a limited environment, the system comprising: a matrix microphone (110) comprising a plurality of microphones (112) configured to detect sound waves approaching from various directions; a sound generator (411) configured to consecutively generate sound impulses in a plurality of frequency bands to be played by the speakers (122) of the loudspeaker system, each generated sound impulse having an impulse duration; a sound recorder (412) configured to register sound received by the microphones (112) of the matrix microphone in a recording storage (413), wherein the sound is registered in response to each generated sound impulse for a period longer than the sound impulse, such as to register direct and reflected sound impulses; and a model generator (414) configured to analyze the recorded sound from the recording storage (413) and to generate a model of the environment including the position and properties of walls (125) and other objects (124) within the environment.
Abstract:
A signal comprising at least three sound events data, characterized in that each sound event comprises: time of event information; information regarding location in space with respect to a reference location point; a movement trajectory in space; orientation information; wherein the signal comprises at least one acoustic sound event further comprising spatial characteristic of the source of the event; information on sampling frequency; information on signal resolution; and a set of acoustic samples of the sampling frequency and at the signal, resolution; at least one textual sound event further comprising a library identifier and a textual data field wherein the textual data is to be used to generate sound by a speech synthesizer; and at least one synthetic non-verbal sound event further comprising at least one code in a data field and a library selection field referring to a music synthesizer library wherein the at least one code is to configure a music synthesizer.
Abstract:
A system for connecting an all-wing carrier with a parasite flying unit, characterized in that the carrier (1) and the parasite flying unit (2) are connected via energy distribution means (11 a, 21a, 11b, 21b) configured to exchange energy bi-directionally, wherein the system further comprises a controller (41) configured to control the direction of the flow and the amount of said energy.
Abstract:
System and method for detecting location of sound sources in a three-dimensional space using linear microphone arrays comprising a plurality of microphones wherein the microphones are located in at least two groups of at least two microphones wherein each group has a different spacing of the respective microphones. Three such linear microphone arrays are used wherein first ends of all three microphone arrays, comprising the same arrangement of microphones, are in proximity or adjacent to each other; and the separate microphone arrays are positioned in different planes in three-dimensional space.
Abstract:
A method for managing uniform logging in and out, the method comprising the steps of: authenticating access to encrypted user credentials database comprising automatically generated credentials; receiving a service or application identifier; retrieving, from the user credentials database stored in a local memory, credentials associated with the service or application identifier; executing authorization process to the service or application, using the retrieved credentials; upon successful authorization: verifying a condition regarding a life of automatically generated credentials; and in case the condition is met automatically generating new credentials for the service or application, and updating the user credentials at the service or application as well as in the user credentials database.
Abstract:
A method for supporting maneuvers of an all-wing carrier aircraft by its parasite flying units, comprising the steps of: selecting (20) a maneuver to be performed; determining (21) sensor values (25) corresponding to selected maneuver; selecting (22) engines of parasites to support the maneuver; activating (23) said engines so that sensor values (25) are matched.
Abstract:
A method for a tactical visualization, the method comprising the steps of: identifying objects and objects of interest on an image acquired by a camera; generating a descriptor for each identified object; transmitting the collected data to a command center; awaiting data from the command center and receiving the data; processing the received information and superimposing it on the image from camera; and providing movement guidance on the composite image and displaying the composite image on a visualizing means.
