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 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.

In a tape cassette (5) to be used for a tape printing device (1), a roll part T0 of a print tape T having a preset tape width is firmly attached to the under surface of a rotation support section (21a) of a tape unit (20) by a lower spool (22). The tape unit (20) is provided with a tape identification section (30) for identifying the type etc. of the rolled tape. In the tape identification section (30), a vertical through hole (61) as a tape width identification part is provided varying its position depending on the tape width. Meanwhile, a cassette case body (32) and a cassette cover (33) of the tape cassette (5) are provided with a tape detection part (50a, 50b) to which the tape identification section (30) can be set or attached, while being provided with a projection (52) as a tape width detection part to be paired with the vertical through hole (61) so that only a tape unit (20) including a rolled print tape having a preset tape width is allowed to be attached to the tape cassette (5). By the composition, erroneous loading of an improper tape unit (20) (to which a tape of a different width has been set) in the tape cassette (5) can be prevented.

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.

The theater optionally comprises a projection screen, a projection room, seating, a dance area, an MC (master of ceremonies) station, changeable scenic designs, special effects equipment, food services and/or a bar.

A mobile terminal includes a projector module configured to project an image onto an external surface to display the image on the external surface and a controller configured to adjust at least one of an area or a position of the displayed image.

A method and device for adjusting the unstored length of tubing directed to improving the use of infusion sets that deliver fluids to a user. The device includes a storage module and other features for adjusting, storing and securing the length of the tubing. The method of adjusting the length of the tubing to a desired length typically comprises removably attaching the tubing to the adjuster, adjusting the tubing by wrapping the tubing around a hub or post of the adjuster, and fixing the length of the unstored tubing by attaching the tubing to a securing device such as a friction structure or fastener

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.

A polarization image capturing section 103 obtains a first polarization image containing polarization information. A polarization information obtaining section 104 obtains first polarization information from the first polarization image. An illumination control section 102 changes an illumination section 101 and again obtains a second polarization image by means of the polarization image capturing section 103. The polarization information obtaining section 104 obtains second polarization information from the second polarization image. A light source dependency estimation section 105 obtains light source dependency from the first and second polarization information obtained from the first and second polarization images. An area dividing section 106 performs an area division by using the polarization information and light source dependency information.

In order to provide an image display system, a projector, a program, an information storage medium, and an image processing method that make it possible to perform calibration without interrupting the display of an image for a presentation or the like, an image processing section of a projector is provided with an area identification section that identifies a display area and a non-display area, based on environmental information measured by a CCD sensor; a brightness change derivation section that derives any change in the brightness of the non-display area; a grayscale correction parameter derivation section that derives a grayscale correction parameter corresponding to the change in brightness; and a 1D-LUT generation section that generates a 1D-LUT used in the correction of brightness in accordance with the grayscale correction parameter.

A data storage cartridge having an data storage device, such as an encased magnetic disk drive assembly, is, in one embodiment, of generally an exterior dimensional form factor of a tape cartridge having a leader block with a hole therethrough for engagement by a threading pin. To distinguish the cartridge from a tape cartridge, the cartridge shell comprises a blocking portion at the location of the leader block hole. A transfer station both identifies the cartridge and indicates the presence of the cartridge at an end of travel in a cartridge receiver, employing an optical source and an opposed sensor directed toward the leader block hole when a cartridge is at the end of travel. In another embodiment, an encased magnetic disk drive assembly is supported and mounted in a cartridge shell by a shock mount. A flex cable interconnects the rear of the encased magnetic disk drive assembly with an external data transfer interface at the opposite side of the cartridge for data transfer with respect to a transfer station and to provide mechanical isolation.
