In order to detect interlace errors in a video signal, one receives successive digitally coded frames, each frame comprising data for a field of a first type and data for a field of a second type (i.e. a top field and bottom field or vice versa).

Image pickup apparatus with shock resistance
An inner cover supported to be rotatable in a panning direction is urged by an elastic member in a direction approaching a dome. When a shock is applied to a dome cover, the inner cover is pressed in a direction away from the dome and touches a supporting member of a fixing portion. As a result deformation of the dome can be suppressed, and a lens unit and a panning rotation unit can be protected. In addition, since the dome cover is suppressed, it is not required to provide a retraction mechanism in the lens unit. Moreover, since no rigidity of the dome cover is required, the dome cover can be reduced in wall thickness and increased in diameter, so that priority is given to optical performance of the lens unit. |

Method and system for global logoff from a web-based point of contact server
A method carried out at a point of contact (e.g., reverse proxy, a web server plug-in, or the like) that serves as an intermediary between a client browser and one or more back-end applications (or application component), wherein each back-end application has the capability to set its own server-side session management data with respect to the point of contact that is independent of any client-side session management data set by the point of contact and used by the point of contact to manage a user session. The method begins as a given back-end application returns a response to a first request that has been issued from the client browser (the first request having been received at the point of contact and passed to a back end application or component for processing). The point of contact intercepts the out-going response, augments server-side session management data associated therewith with a “stamp,” and forwards to the client browser the response together with the server-side session management data as augmented to include the stamp. The stamp provides a way for the point of contact to later determine whether the server-side session management data, if received with another user request, is valid for that request. Later, upon receipt at the point of contact of a new user request that includes the server-side session management data (and stamp), the point of contact uses the stamp to determine whether the new request is valid. If so, the point of contact removes the stamp from the server-side session management data and forwards the new request (and the management data) to the back-end application for handling. |

Mechanism for controlling a process on a computing node based on the participation status of the computing node
A mechanism is provided for controlling a process on a computing node. In one implementation, a determination is made as to whether the participation status of a computing node has changed. The participation status may, for example, be active, in which case the computing node is participating in the processing of requests from a request handler, or it may be passive, in which case the computing node is not participating in the processing of requests from the request handler.
