Abstract: PCT No. PCT/SE96/00788 Sec. 371 Date Mar. 13, 1998 Sec. 102(e) Date Mar. 13, 1998 PCT Filed Jun. 17, 1996 PCT Pub. No. WO97/00596 PCT Pub. Date Jan. 3, 1997An oven having two sources of heat is controlled to perform high quality results when the user simply chooses the class of food on a front panel. A first source of heat is active during a first period until a second source of heat takes over during a second period until the temperature rises to a specific temperature threshold. The time required to reach this specific temperature threshold is measured. The measured time is dependent on the size and type of the food to such a degree that the remaining baking time can be determined with high precision along with the required baking temperature during the remaining baking time. The oven then preforms baking for the remaining baking time using either or both of the first and second sources of heat and informs the user about the remaining baking time.

Abstract: A filtering device consisting of a nonadaptive feedback filter that generates active attenuation of the vibration on the framework, without generating instability in a first frequency band, and an adaptive feedforward filter is disclosed. Feedforward filtering coefficients are adapted in real time according to an algorithm chosen to minimize the energy of the types of vibration which are picked up by a sensing device as a function of the energy of the types of vibration which are picked up by the sensing device, and of the previously measured transfer function, in the presence of a feedback filtering device and in the absence of a feedforward filtering device, between an actuator device and a first sensing device. The device makes it possible to linearize the feedback attenuation throughout a second frequency band which is wider than the first frequency band, to accelerate the convergence of the minimization algorithm and to enhance the robustness of the feedforward filter.

Abstract: There is disclosed a method for moving an optical head from an initial track (10) to a target track (11) on a storage medium (1). The total number of tracks (3) to be crossed is determined, and the optical head is moved toward the target track (11). A reflectivity level of light from the storage medium (1) is measured, and a tracking error signal is derived from the reflectivity level. The tracking error signal has both true and false indicators of track crossings. A data indicator signal is derived from the reflectivity level, having indicator points corresponding to the false indicators of track crossings. A track count number is incremented for each true indicator of a track crossing, and the optical head is stopped when the track count number equals the total number of tracks (3) to be crossed. Another method is disclosed whereby a track count signal is generated from the tracking error signal and the data indicator signal. The track count signal indicates track crossings corresponding to the true track crossing indicators in the tracking error signal.

Abstract: A teleconferencing system that integrates separate real-time and asynchronous networks - the former for real-time audio and video, and the latter for control signals and textual, graphical and other data - in a manner which closely approximates the experience of face-to-face collaboration. The system provides an audio/video (AV) path (13) for carrying AV signal among the workstations, a video mosaic generator (36) for combining images, and an audio summer or mixer (38). At least part of the AV path (13b) is implemented with unshielded twisted pair wiring. The system architecture is readily scalable to the largest enterprise network environments. It accommodates differing levels of collaborative capabilities available to individual users and permits high-quality audio and video capabilities to be readily superimposed onto existing personal computers and workstations (12) and their interconnecting LANs (10) and WANs (15). In the case of a plurality of geographically dispersed LANs (10) interconnected by a WAN (15), the demands made on the WAN are significantly reduced by employing multi-hopping techniques, including avoiding the unnecessary decompression of data at intermediate hops, as well as video mosaicing and cut-and-paste technology.

Abstract: This new machine winds pre-stretched film from a supply spool, onto a reception spool. Either or both are driven. A novel feature is relative axial movement of the spools, effecting periodic variation in the position of the film edges with respect to the axis (5) of the reception spool. The movement is such that the edge profile (21) of the spooled film, is caused to exhibit a frustrated- or near conical profile. Also claimed are: the corresponding method of spooling to produce the conical profile described; and the spool of film, formed by the winding process.
