Title: Differential multi-cell intrusion locating cable
Inventor: HARMAN R KEITH
IPC: G08B13/24
Filed: 1994-12-07
Granted: 2003-05-20
Abstract: A transducer cable (5) includes outer conductor (1) inner conductor (2). dielectric (6) therebetween, and a longitudinal passage (4) with sense wire (3) loosely disposed therein extending through said dielectric. Intruder-caused vibration (7) of the cable results in relative movement of the sense wire and outer conductor. causing corresponding sense wire impedance change. A carrier signal (8) transmitted down the inner conductor electromagnetically couples energy to the sense wire. Said impedance change causes reflection of some of the coupled energy, the reflection is sensed by a receiver circuit that in turn produces an indication of intrusion.  The receiver circuit includes a system that digitizes the received signals at successive times that correspond to successive sections of the cable, and produces targe response values for sections of the cable undergoing impedance changes.  Target responses in several adjoining sections are interpolated precisely locate the intruder-caused vibration.

Abstract: An apparatus and method for facilitating the respiration of a patient are disclosed which are particularly useful in treating mixed and obstructive sleep apnea and certain cardiovascular conditions, among others, by increasing nasal air pressure delivered to the patient's respiratory passages just prior to inhalation and by subsequently decreasing the pressure to ease exhalation effort. The preferred apparatus includes a patient-coupled gas delivery device for pressurizing the patient's nasal passages at a controllable pressure, and a controller coupled with the delivery device having a pressure transducer for monitoring the nasal pressure and a microcontroller for selectively controlling the nasal pressure. In operation, the controller determines a point in the patient breathing cycle just prior to inhalation and initiates an increase in nasal pressure at that point in order to stimulate normal inhalation, and subsequently lowers the nasal pressure to ease exhalation efforts.

Abstract: The device comprises, inside a case, a tightening cam (7) hinged about an axis (8) such that, unused, it does not engage a belaying rope (2) passing through the case and, when the device is subjected to a set acceleration downwards, it pivots towards the rope (2) to tighten it to the case with self-tightening effect. On the cam (7) is mounted a detecting roller (10) which co-operates with the rope (2) when the cam (7) is unused. A spring actuated (13) friction piece (12), at a certain rotational speed of the roller (10), subjects it to a resisting moment which triggers off the pivoting of the cam (7) in the tightening direction. A lever (15), to which the user is linked, engages in a unidirectional manner the cam (7) to push it in tightening position if the user falls. The device simultaneously triggers off several tightening effects in case of a fall.
