摘要： The apparatus (40) has a sensor (41) disposed on the first end (42) of an elongate connector (43) by means of fixed interface link (79). A recorder unit (44) is disposed on the second end (45) of the connector (43) opposite the first end (42). The connector (43) is bendable within a predefined curvature range. When the apparatus (40) is deployed into the sea, it is adapted to free-fall through the body of water and to land on the seafloor such that the sensor (41) is spaced apart from the recorder unit (44). The length of the connector (43) is dynamically variable within a predefined range so as to eradicate or minimise coupling of any vibration of the recorder unit (44) to the sensor (41). The physical separation of the sensor (41) and the recorder unit (44), together with the mechanical characteristics of the connector (43), ensure that the sensor (41) is substantially vibrationally de-coupled from the recorder unit (44). In other words, the mass of the recorder unit (44) does not inhibit the sensor (41) from responding to seismic waves, and any vibration of the recorder unit (44) (for example due to any water currents that may be flowing in the vicinity of the recorder unit (44) ) is not substantially transmitted to the sensor (41). Hence, the connector (43) constitutes a positive mechanical connection between the sensor (41) and the recorder unit (44) so far as maximum separation distance is concerned, however not so far as seismic or flow induced vibrations are concerned.
摘要翻译：装置（40）具有通过固定接口连杆（79）设置在细长连接器（43）的第一端（42）上的传感器（41）。记录器单元（44）设置在与第一端（42）相对的连接器（43）的第二端（45）上。连接器（43）可在预定的曲率范围内弯曲。当装置（40）展开到海中时，其适于自由落下水体并落在海底上，使得传感器（41）与记录器单元（44）间隔开。连接器（43）的长度在预定范围内是动态可变的，以便消除或最小化记录器单元（44）的任何振动与传感器（41）的耦合。传感器（41）和记录器单元（44）的物理分离以及连接器（43）的机械特性确保传感器（41）与记录器单元（44）基本上振动地脱耦合。换句话说，记录器单元（44）的质量不会阻止传感器（41）响应于地震波，并且记录器单元（44）的任何振动（例如由于可能流入的任何水流）记录器单元（44）的附近）基本上不传送到传感器（41）。因此，只要涉及最大分离距离，连接器（43）就构成了传感器（41）和记录器单元（44）之间的正的机械连接，然而就地震或流动引起的振动而言并不是这样。
