Abstract:
A method and a device for the acoustic detection of a one lung intubation situation in a human subject are disclosed. According to some embodiments, the disclosed method includes computing an autoregressive moving average (ARMA) or an autoregressive function of electrical signals received from acoustic detectors placed at different locations on the body of the subject. Appropriate locations for acoustic detectors include the back region and the chest region. The disclosed method and apparatus are insensitive to uncancelled, random background noise with a loudness associated with an operating room or intensive care ward. The disclosed device is configurable so that the relative occurrence rate of missed detections or false negatives and false positive alarms can be modified. In one exemplary embodiment, the device is adapted such that at most 9% of identifications are false positive identifications, and at most 2% of identifications are false negative identifications.
Abstract:
Provided is an RPG disruption system (RDS) for protecting an enclosure against RPG's, the system including a casing fixed in close proximity to a wall of the enclosure facing an anticipated RPG threat. The casing includes an anvil accommodating a propelling mechanism for propelling the disrupting element, and an activating system for activating the propelling mechanism so as to propel the disrupting element towards an approaching RPG, to thereby neutralize it.

Abstract:
A rotary sprinkler comprising a rotor (16) with an axle (38) having a tip, and a thrust hearing (14) with a socket (26) having a bottom (30), the socket being adapted to receive for rotation the axle so that the tip abuts the bottom in a contact zone. The sprinkler further comprises a hard element (42) constituting a part of the bottom or of the tip. The hard element (42) is made of harder material than the axle or the socket, thereby reducing their wear.
Abstract:
Briefly, some embodiments of the invention may provide devices, systems and methods for modifying video signals. In accordance with some embodiments of the invention, a device may include a video adaptor to receive a first video signal having an image rendering code embedded therein, and to produce a second video signal based on the first video signal and the image rendering code.
