摘要： A method of identifying a gemstone, particularly a diamond by: exciting the gemstone to cause it to emit luminescence radiation according to a luminescence spectrum unique to the respective gemstone, in which the luminescence intensity uniquely varies as a function of wavelength; measuring the level of the luminescence radiation at a plurality of preselected wavelengths of its luminescence spectrum; and utilizing the levels of the luminescence radiation at the preselected wavelenths to identify the respective gemstone and to distinguish it from other gemstones.

摘要： A system for reducing damage by birds to an airplane, the system including: (a) a detector mounted on the airplane, operable to detect a bird in a vicinity of the airplane and to generate detection information indicative of motion of the bird; (h) a processor, connected to the detector, configured to analyze the detection information and to selectively trigger activation of a jetting system that is mounted on the airplane in response to a result of the analysis; and (c) the jetting system, operable to jet a high pressure jet onto a bird.

摘要： 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.

摘要： 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.

摘要： 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.
