A multimedia optical disk is provided. The multimedia optical disk includes a data area for storing objects which include moving picture data and at least one of audio data and sub-picture data. The multimedia optical disk also includes an index area for storing reproduction orders of the objects. Route information in the index area includes a sequence of addresses of objects whose alignment represents a reproduction order. Chain control information in the index area corresponds to the route information. The chain control information, being effective in reproducing objects specified by the alignment of the sequence of addresses (objects specified by the alignment of the sequence of addresses are called a chain), instructs the reproduction apparatus to have a navigation control of the chain. A piece of moving picture data having a certain time period is reproduced at the same timing as a piece of audio data and a piece of sub-picture data. A piece of sub-control information, being effective in reproducing moving picture data, sub-picture data, and audio data stored in a small unit instructs the reproduction apparatus to have a navigation control of the data stored in the same small unit.

An electric storage device of an electric powered vehicle is configured to be chargeable by a charging facility.

A recording medium and method and apparatus for reproducing and recording text subtitle streams are disclosed. The text subtitle stream includes a dialog style segment defining a set of region styles and at least one dialog presentation segment. Each dialog style segment contains at least one region of dialog text, where each region of dialog text includes link information configured to link each region of dialog text to one of the set of region styles defined in the dialog style segment. For example, the link information is a region style identification which uniquely identifies the region style linked to each region of dialog text. When each region of dialog text is reproduced, the region style identified by the region style identification is applied.

Disclosed herein is a method of recording and reproducing surveillance images in a Digital Video Recorder (DVR).

A dynamic load fixture (DLF) applies a torsion load to a unit under test (UUT) to achieve the demanding aerodynamic load exposures encountered by a control actuation system (CAS) in flight. Instead of fixing the end of the torsion bar, the DLF controls the application of torque to the torsion bar, hence the UUT via a DLF motor. The dynamic load can be independent of the angular rotation of the UUT, which allows the DLF to more effectively reproduce desired acceptance tests such as torque-at-rate and nonlinear loads. Furthermore, application of the loads through a torsion bar allows the system the compliance needed to generate precise loads while allowing for the flexibility of changing torsion bars to test a wide variety of UUT on one test platform. To achieve the demanding aerodynamic load exposures encountered by a CAS in flight, the controller must be able to respond both very fast and very precisely. Control is enhanced by the thorough characterization of the DLF and application of either “classic” negative feedback control or “modern” state-space control methods of linear observers and quadratic optimum control.
