Abstract: A computer readable storage medium includes executable instructions to receive a specification for requested data in a log based replication system where data changes are retrieved from both a transaction log and a database. It is determined that the requested data is compromised. A search for a data image containing the requested data is initiated. The data image is accessed to secure the requested data. The requested data is returned.

Abstract: A computer readable medium includes executable instruction to compare databases. The executable instructions are configured to identify when a segment of a first database is conditionally out of synchronization with a corresponding segment of a second database to establish a conditionally out of synchronization state at a first time. Executable instructions allow a latency period after the first time in which changes are made to the first database and the second database. Executable instructions also determine after the latency period whether the segment of the first database is in synchronization with the corresponding segment of the second database. Executable instructions also populate a resynchronization table, which is used by a replication mechanism to bring asynchronous rows into synchronization.

Abstract: A video system includes a video source transmitting an output signal on a transmission line. The output signal has a format such that first portions of the output signal include active video signals and second portions of the output signal lack active video signals. Each of a plurality of video receivers displays images based upon the active video signals and transmits a respective data signal on a respective one of a plurality of ports. A distribution device is electrically connected to the transmission line and to each of the ports. The distribution device transmits each of the data signals to the video source on the transmission line only during time periods when the second portions of the output signal are being transmitted on the transmission line. The distribution device includes a plurality of amplifiers, each having an input and an output. Each of the amplifiers receives signals on the input for transmission on the output as amplified signals.

Abstract: The systems and methods described herein are directed at controlling access to a data structure. A data field is included within the data structure. The data field includes information about the accessibility of the data structure. In response to an attempt to access the data structure by a first thread, the data field is configured to identify that the data structure is not accessible by another thread. The first thread can then access the data structure. In response to an attempt to access the data structure by a second thread, the second thread is configured to determine from the data field that the data structure is being accessed by the first thread.

Abstract: A control apparatus is provided for use by a person located on a bed to control at least one function. The bed includes a frame, and a patient support surface supported by the frame. The apparatus includes a control unit configured to control the at least one function.

Abstract: A camera module for use in a surveillance camera system is provided. The camera module includes a housing and a pan-and-tilt mechanism that is mounted to the housing. The pan-and-tilt mechanism includes a pan motor for panning a camera and a tilt motor for tilting the camera. The pan motor is mounted on the pan-and-tile mechanism so as to be stationary relative to the housing. A slip ring, mounted to the pan-and-tilt mechanism, provides electrical connections to the tilt motor and the camera and a flex cable connects the camera to the slip ring. Also provided are methods for controlling unique functions of the surveillance camera system. Calibration of a home pan position for the camera is achieved by monitoring an optical homing sensor. Calibration of a home tilt position for the camera is accomplished by driving the camera against a stop. Thereafter, pan and tilt positions of the camera are tracked relative to the home pan and tilt positions.

Abstract: A video surveillance system includes a plurality of remote surveillance units, each of which has a video camera mounted in a dome housing. The video camera is panned and/or tilted to a desired orientation within the dome by a pan motor and/or a tilt motor. The surveillance system also includes a keyboard for entering user commands, a joystick for controlling the positioning of the cameras, a central processing unit for interpreting the user commands and the joystick movements, and a communication system for issuing operating commands to the remote surveillance units. Each remote surveillance unit is constructed and arranged to store and to recall selected camera control parameters in association with selected pan and tilt coordinates in response to commands entered by the user. The camera control parameters include white balance, focus, and shutter speed settings for the camera. Additionally, automatic control of the camera exposure, white balance, and focus is provided.

Abstract: Disclosed is a premix and a complete mix for preparing bakery products suitable for microwave heating. The premix includes protein in an amount of 4.5 to 25.0 by weight and 7 to 50 shortening by weight. The premix may be combined with other ingredients to prepare a mix for preparing the bakery product. The mix may include from 46 to 80 parts flour, 4 to 22 parts shortening, and 4 to 11 parts protein material.
