Embodiments of the invention provide techniques for ensuring that the contents of a non-volatile memory device may be relied upon as accurately reflecting data stored on disk storage across a power transition such as a reboot. For example, some embodiments of the invention provide techniques for determining whether the cache contents and / or or disk contents are modified during a power transition, causing cache contents to no longer accurately reflect data stored in disk storage. Further, some embodiments provide techniques for managing cache metadata during normal (“steady state”) operations and across power transitions, ensuring that cache metadata may be efficiently accessed and reliably saved and restored across power transitions.

The present invention provides a computer system and software that implements and supports a method to permit a digital media peer-to-peer or peer to server exchange while providing a secure and high speed transmission of media files across an internet, intranet or cable network in such a manner as to avoid illegal or un-permitted end user digital file sharing or copying. More particularly, the invention provides a method that combines a digital media encryption technique and unique user key to permit transmission of digital media information in a very compressed or compacted small-size file that is essentially incapable of being decoded without a legitimate user key.

Embodiments of the invention provide techniques for managing cache metadata providing a mapping between addresses on a storage medium (e.g., disk storage) and corresponding addresses on a cache device at data items are stored. In some embodiments, cache metadata may be stored in a hierarchical data structure comprising a plurality of hierarchy levels. Only a subset of the plurality of hierarchy levels may be loaded to memory, thereby reducing the memory “footprint” of cache metadata and expediting the process of restoring the cache metadata during startup operations. Startup may be further expedited by using cache metadata to perform operations associated with reboot. Thereafter, as requests to read data items on the storage medium are processed using cache metadata to identify addresses at which the data items are stored in cache, the identified addresses may be stored in memory. When the computer is later shut down, instead of having to transfer the entirety of the cache metadata from memory to storage, only the subset of the plurality of hierarchy levels and / or the identified addresses previously loaded to memory may be transferred (e.g., to the cache device), thereby expediting the shutdown of the computer.

A piston-cylinder assembly has a principal structural group including a cylinder and another principal structural group including a piston rod which has a part-length axially displaceably arranged within the cylinder. The piston rod adopts a default stroke position without external displacement forces acting on the piston-cylinder assembly, the default position being determined by positioning equipment. The positioning equipment includes at least one energy accumulator which acts in the inward and outward movement directions of the piston rod as a function of the stroke position of the piston rod. The at least one energy accumulator includes a tension spring arrangement and a compression spring arrangement. Each of the tension spring arrangement and the compression spring arrangement has a first end which acts in a stationary manner on one of the first and second principal groups and a second end which acts on the other of the first and second principal groups at least with the piston rod outside the default stroke position.

The inkjet head comprises: a nozzle which discharges droplets of ink through an ink discharge port to perform recording onto a recording medium, the ink being supplied through a supply duct, at least partial cross section of the nozzle on a side of the ink discharge port broadening toward the ink discharge port; and a device which moves a position of a boundary surface of the ink between a first boundary surface keeping position inside the nozzle at which the boundary surface of the ink is kept for recording and a second boundary surface keeping position inside the nozzle at which the boundary surface of the ink is kept for cleaning the nozzle under pressure less than or equal to ink discharging pressure, wherein fouling around the nozzle is collected by moving the position of the boundary surface of the ink between the first boundary surface keeping position and the second boundary surface keeping position.

A method for restoring visual output to a display device. The method includes detecting a display device connection change on an output connector and changing output settings to a compatible output mode on the output connector. The method further includes cloning graphics output to the output connector. The graphics output is modified for display on the second output connector. Subsequently, a control panel application is executed to present an on-display control for changing the output mode of the first output connector.

To ensure that the contents of a non-volatile memory device cache may be relied upon as accurately reflecting data stored on disk storage, it may be determined whether the cache contents and / or disk contents are modified during a power transition, causing cache contents to no longer accurately reflect data stored in disk storage. The cache device may be removable from the computer, and unexpected removal of the cache device may cause cache contents to no longer accurately reflect data stored in disk storage. Cache metadata may be managed during normal operations and across power transitions, ensuring that cache metadata may be efficiently accessed and reliably saved and restored across power transitions. A state of a log used by a file system may be determined prior to and subsequent to reboot of an operating system in order to determine whether data stored on a cache device may be reliably used.

A method and system for restoring output to a display device. The method includes receiving a request to restore the output, modifying output settings so output is visible on a display device, and invoking an output configuration application. The method and system allow a user to restore the output on a display device after the output has been configured to settings which exceed the capabilities of the display device.

A connector enables a size reduction while maintaining a function of reliably preventing terminal members from falling out of terminal holes. In this connector, a plate spring piece is provided in a terminal hole of a connector housing, with a length thereof set to an axial direction of the terminal hole, and an engaging pawl protrudes from the plate spring piece. When a female terminal is inserted into the terminal hole, the engaging pawl engages with the female terminal and bends the plate spring piece downward, enabling the insertion. When the female terminal is inserted to a predetermined depth in the terminal hole, the plate spring piece returns and the engaging pawl moves into an engaging hole of the female terminal. The plate spring piece has a structure of which one length direction end portion and one side portion, along the length direction, are fixed to the connector housing.

A liquid ejecting apparatus includes a liquid ejecting head that is provided with a plurality of nozzle openings that discharge a liquid, and pressure generation units that generate pressure changes in pressure generation chambers that are respectively in communication with the nozzle openings, a detection unit that detects a discharge fault of liquid droplets of the liquid ejecting head for each of the nozzle openings, and a control unit that controls the pressure generation units, in which the control unit has a discharge prohibition mode in which the driving of a pressure generation unit that corresponds to a nozzle opening in which a discharge fault is detected, is prohibited after the corresponding discharge fault is detected while recording is underway.

A filter system for intake air of an internal combustion engine has a housing with a cover. A filter element is arranged in the housing. An inlet feeds a medium to be filtered into the housing and an outlet discharges the medium from the housing. The filter element has a filter body with first end face and opposite second end face. The filter element has an open first end plate at the first end face and a second end plate at the second end face. A support tube is arranged concentrically about a longitudinal axis in the housing and attached with a first end to the housing. The support tube is arranged in the interior of the filter element and radially supports the filter body. The second end plate rests on the second end of the support tube and on an inner cover contour of the cover with anti-rotation action.

An electronic timepiece is operated with a power-supply voltage from a secondary battery charged with a voltage from a solar panel. An oscillation circuit generates and supplies a clock signal to a CPU when the voltage charged to the battery is lower than a first voltage. A reset circuit resets the CPU when the voltage charged to the battery does not exceed a second voltage higher than the first voltage, and cancels the reset of the CPU when the voltage charged to the second battery exceeds the second voltage. The CPU starts an operation when the voltage charged to the secondary battery exceeds the second voltage and the reset is cancelled, and performs a time-of-day display on a display unit when the voltage charged to the secondary battery is equal to or higher than a third voltage higher than the second voltage.
