A system for empirically diagnosing a condition of a monitored system. Estimates of monitored parameters from a model of the system provide residual values that can be analyzed for failure mode signature recognition. Residual values can also be tested for alert (non-zero) conditions, and patterns of alerts thus generated are analyzed for failure mode signature patterns. The system employs a similarity operator for signature recognition and also for parameter estimation. Failure modes are empirically determined, and precursor data is automatically analyzed to determine differentiable signatures for failure modes.

A method of signaling between a photovoltaic module and an inverter module. The inverter module is connected to the photovoltaic module. In an initial mode of operation an initial code is modulated thereby producing an initial signal. The initial signal is transmitted from the inverter module to the photovoltaic module. The initial signal is received by the photovoltaic module. The operating mode is then changed to a normal mode of power conversion, and during the normal mode of operation a control signal is transmitted from the inverter to the photovoltaic module. A control code is demodulated and received from the control signal. The control code is compared with the initial code producing a comparison. The control command of the control signal is validated as a valid control command from the inverter module with the control command only acted upon when the comparison is a positive comparison.

A magnetic-tape cartridge case has the same general geometry and dimensions of a conventional cartridge, but an additional slanted wall is incorporated between two other walls at one end of the cartridge case. A memory chip is placed with its antenna adjacent to the additional wall inside the case. The memory chip is accessible by non-contact means from two substantially orthogonal directions and the antenna of the external reading device may be placed in closer proximity than heretofore possible and may be optimally oriented to improve data transmission.

There is provided a safe image display apparatus for projecting an image on a screen that can minimize a stimulus to eyes, retinae and optic nerves from projected light entering into the eyes directly. By comparing a displayed image captured by a camera with an input image signal, a changed area is detected as a difference area and, then, a projected image signal is generated wherein a picture area image signal in the input image signal that corresponds to this difference area is masked by a black signal. The obtained projected image signal is projected onto the screen.

A tape cartridge is provided with reliable reel lock and motor / reel coupling mechanisms whose functions are both accomplished during a single motion of the cartridge relative to the drive motor. The motor / reel coupling includes a circular set of gear teeth on the bottom of the tape reel which meshes with a complementary set of gear teeth on a motor coupling rotated by the motor when the cartridge is loaded into the tape drive and the cartridge and motor are moved towards each other. An engagement force to maintain the coupling is provided by an engagement spring in the cartridge which biases the reel towards the motor. Reel locking is accomplished by providing a second circular set of gear teeth on a top side of the tape reel which meshes with a complementary set of gear teeth provided on a slidably mounted locking bracket inside the tape cartridge. A lock spring normally biases the locking bracket towards the top of the tape reel, thus locking the reel when the cartridge is not engaged with the motor. When the cartridge and the drive motor are moved towards each other, the motor coupling engages the bottom of the tape reel, and a projection on the motor coupling extends into the tape cartridge to slide the locking bracket out of engagement with the teeth on the top of the tape reel, thereby unlocking the reel. Thus, reel unlocking and motor / reel coupling are accomplished with a single motion by reliable mechanisms.
