Abstract: This disclosure includes a portable data storage device comprising a mass data storage device, a cartridge housing enclosing a mass data storage device, and a flexible interconnect. The flexible interconnect includes an external electrical connector mechanically coupled to the cartridge, an internal electrical connector mechanically and electrically coupled to a data port of the mass data storage device, and a set of flexible electrical conductors electrically coupling the external electrical connector to the internal electrical connector. The flexible electrical conductors are routed within the cartridge such that no portion of the set of flexible electrical conductors lies in a volume defined by the space between the external electrical connector and the internal electrical connector.

Abstract: A tunnel boring machine (90) having a rotating cutter head (93) that rotatably supports a plurality of cutter assemblies (10). A plurality of instrument packages (50) are attached to the rotating cutter head, each instrument package having a distal end in contact with an associated cutter assembly. The instrument packages include a plurality of sensors including an accelerometer (32), magnetometer (33) and temperature sensor (34), for monitoring the associated cutter assembly. The sensors are mounted in a distal end of the instrument packages that is biased to remain in contact with the cutter assembly. The instrument packages include a wireless transmitter, and they are interconnected in a mesh or peer to peer network. A power supply (176) such as a battery pack is provided for each instrument package. The data from the sensors may be used to control operation of the tunnel boring machine and/or to monitor the condition of the cutter assemblies.

Abstract: This disclosure includes an elastic shock mount for a mass data storage device cartridge comprising a shock mount body forming a void configured to receive a mass data storage device; and a set of elastic shock mount protrusions extending outward from the shock mount body. The elastic shock mount protrusions are configured to transfer shock forces experienced by the cartridge housing to durable portions of the mass data storage device.
