Patent number: 9846235Abstract: There are provided methods and systems for producing a wave-beam having substantially constant lateral extent over a desired range of distances, and interrogation and response system and methods utilizing the same. The method for producing a wave-beam having substantially constant lateral extent includes generating a plurality of at least partially incoherent constituent wave-beams having different divergences and directing the plurality constituent wave-beams to propagate along substantially parallel propagation axes such that the constituent wave-beams at least partially overlap and superpose to form a combined wave-beam. The divergences and intensities of the constituent wave-beams are selected such that the combined wave-beam has a desired substantially constant extent over a desired range of distances along said propagation axes.Type: GrantFiled: August 8, 2013Date of Patent: December 19, 2017Assignee: Israel Aerospace Industries Ltd.Inventors: Abraham Aharoni, David Lou Alon, Aharon Yifrach

Patent number: 6626397Abstract: An unmanned flying vehicle comprises an autonomous flying wing having at least two wing portions arranged substantially symmetrically about a center portion. Each wing portion is pivotally attached to each adjoining portion such that the wing portions are foldable for storage and openable for deployment. A preferred form is the so-called seagull wing having four wing portions. The vehicles may be programmable from a mother aircraft whilst being borne to a deployment zone using a data link which may be wireless.Type: GrantFiled: July 2, 2001Date of Patent: September 30, 2003Assignee: Elsbit Technologies Ltd.Inventor: Aharon Yifrach

Patent number: 5463599Abstract: A buffer system for radio receivers includes an analog-to-digital converter, a digital cyclic storage device for continuously storing in digital form the audio signals last outputted thereby over a predetermined time interval, and a control circuit including a mode selector switch to select a Skip Mode, in which the receiver audio circuit receives the signals from the cyclic storage device with a slowly increasing delay from real-time, and another switch to connect the audio circuit to receive the audio signals real-time, and thus to skip a part of the broadcasted information. The mode selector may also select a Standby Mode for storing information broadcasted before the receiver has been turned on, and/or a Forward Mode for storing information broadcasted after the receiver has been turned off.Type: GrantFiled: August 23, 1994Date of Patent: October 31, 1995Inventors: Aharon Yifrach, David S. Newman

Patent number: 5329320Abstract: A buffer system for TV receivers includes a cyclic storage device connectible to the demodulation circuits for continuously storing the audio and video signals last outputted thereby only over a predetemined time interval, enabling the viewer to jump-back to see a preceding portion of the TV broadcasts. In one described embodiment, the viewer normally sees the broadcasts in a real-time manner but may depress a button to see the broadcasts in a delayed-time manner via the cyclic storage device. In a second described embodiment, the viewer normally sees the broadcasts in a real-time manner, may depress a button to freeze a part of the broadcast in another storage device, and may later depress another button to play back the portion frozen.Type: GrantFiled: December 3, 1992Date of Patent: July 12, 1994Inventor: Aharon Yifrach
