    摘要： The tape in a data cartridge has a beginning of tape (BOT) zone adjacent a leading end, a load point (LP) zone adjacent the BOT zone, an end of tape (EOT) zone adjacent a trailing end, an early warning (EW) zone adjacent the EOT zone, and a data recording (DR) zone between the LP and EW zones. Servo tracks extending between the BOT and EOT enable the closed-loop servo operation of a tape deck during the recording of data at data flux transition densities within a predetermined range of flux transition densities. A BOT indicator includes a first type magnetic marker extending throughout the BOT zone and has a BOT flux density. An LP indicator includes spaced second type magnetic markers on the servo tracks at the border of the LP and DR zones. An EW indicator which is identical to the LP indicator is located on the servo tracks at the border of the DR and EW zones. An EOT indicator includes a first type marker extending throughout the EOT zone and has an EOT flux density. Digitally encoded cartridge information indicators including the spaced second type markers are located in each of the BOT and EOT zones. The BOT and EOT flux densities are different from one another, and sufficiently different from the data flux transition densities to enable the BOT and EOT indicators to be distinguished from the data. The second type markers of the LP and EW and cartridge information indicators are sufficiently different from the servo carrier flux density to enable the indicators to be distinguished from the servo carrier.

    摘要： A multi-axis fatigue testing device includes a multi-axis test fixture having a multiple input, multiple output mechanical linkage driven by a plurality of actuators and a controller operating each of the plurality of actuators in real time and in synchronization to produce user-defined multiple fatigue cycle profiles. At least one of the actuators driving the mechanical linkage acts against an artificial load characterized by a stiffness. The stiffness is selected to increase a resonance frequency of the test fixture to allow fatigue testing at higher frequencies for a wider range of samples.

    摘要： A multi-sample conditioning system may include a sample chamber for each sample or a sample chamber holding one or more samples. Multiple samples enable replication for statistical analysis and individual sample chambers enable individual nutrient flow profiles for each sample. A mechanical imbalance may be created when a sample chamber is removed or when samples of different stiffness are conditioned together. The mechanical imbalance may result in an undesired alteration of the desired conditioning profile and increase the variation in the conditioning profile applied to each sample. An asymmetric-loading support assembly provides a low friction support to reduce the undesired alteration of the desired conditioning profile applied to the samples and reduce unwanted reaction loads on the conditioning drive mechanisms. The asymmetric-loading support assembly preferably includes a flexure as the low-friction, high-stiffness support. Other examples that can provide low-friction, high-stiffness support include air bearings, magnetic bearings, and hydraulic bearings.
