Abstract: Remote control of subscriber access to premium programs on a cable television system or the like is provided. A signal path (13) carries program signals received from a cable television system. A switchable port (20) coupled to the signal path is identified by a logical channel number. First data are received and stored from the cable television system assigning a service code to the logical channel. Second data are received and stored from the cable television system identifying authorized service codes. The assigned logical channel service code is periodically compared to the stored authorized service codes to determine if the logical channel is authorized. The port (20) is switched to provide or deny access to a program signal carried on the signal path, depending on whether the service code assigned to the logical channel identifying the port is authorized. A plurality of ports (20,22,24,26) can be provided to enable subscriber access to different premium services. Each port (20,22,24,26) can couple a trap (30,32,34,36) to the signal path, alternately bypass the trap, or alternately open the signal path to disconnect a subscriber.

Abstract: An infectious waste, a solid chlorite salt, a solid acid and a preheated aqueous solvent are mixed in a treatment volume. At least a portion of the chlorite salt and acid is dissolved in the preheated aqueous solvent incident to mixing and is reacted to form a treatment solution containing a chlorine dioxide disinfectant and a byproduct acid salt. The infectious waste is contacted with the chlorine dioxide in the treatment solution which attacks and destroys the infectious constituents of the waste, thereby decontaminating the waste. Upon dewatering, the decontaminated waste is suitable for landfilling. Process control is exercised by controlling the temperature of the aqueous solvent. A solvent temperature is selected which optimizes both the chlorine dioxide concentration in the treatment solution and the reactivity of the chlorine dioxide with the infectious constituents. Continuous monitoring of the chlorine dioxide concentration in the treatment solution enables adjustment of the solvent preheat temperature to optimal values in accordance with the dynamics of the treatment system.

Abstract: The method of the present invention may be utilized to provide variable authority level user access control for a plurality of resource objects within a distributed data processing system having a plurality of resource managers. A reference monitor service is established and a plurality of access control profiles are stored therein, each including an identification of a selected user and a specified level of authority associated with that selected user. Thereafter, selected access control profiles are exchanged between the reference monitor service and a resource manager in response to an attempted access of a particular resource object controlled by that resource manager. The resource manager may then control access to the resource object by utilizing the exchanged access control profile to determine the extent access is permitted by means of the specified level of authority contained therein. In a preferred embodiment of the present invention, the access intent of a selected user is determined in conjunction with an attempted access of a particular resource object and stored. Thereafter, a comparison of the stated access intent with the specified level of authority contained within the access control profile may be utilized to grant or deny access.

Abstract: This invention is for magnetic actuators which are composed of individually controlled layers. Each layer comprises a stationary sheet 34, a movable sheet 30 and a roller 40 between the sheets. Each layer may either have ribs 32 or sheet portions having conductors, remanent portions or permeable portions which apply a magnetic force against the roller to move the sheets. The magnetic force may be between a current carrying roller and a current carrying rib or sheet portion, a current carrying roller and a remanent rib or sheet portion, a current carrying roller and a permeable rib or sheet portion, a magnetic roller and a current carrying rib or sheet portion, or a permeable roller and a current carrying rib or sheet portion. The sheets in each layer may be moved in parallel or normal directions. When the layers are stacked, actuators may be made. The actuators can be controlled in pairs or larger groups to position and move objects and motor shafts. Thus motors, generators and actuators can be made. By using Fourier mechanical summing of the layers smooth walking motion of the actuators can move and position objects and drive motor shafts with minimal frictional loss of energy and without the use of bearings or lubricants.

Abstract: A pointing device-driven interface apparatus and method for enabling a user to enter data (in the form of options) into a computer system. User data files are maintained which indicate the relative frequency with which the user has entered sequences of options. The sequences are of a predetermined length. The user data is consulted to predict the most likely options to be entered next by the user. These options are presented to the user on a template. A stroke made by the user with the pointing device is then interpreted in light of the template and a syntax of strokes. An action associated with the interpretation is then carried out. An example of the action is communicating a character to a software application, updating the sequence, and repeating the consultation, presentation, interpretation and carrying out just described.

Abstract: A first apparatus for recording/reproducing a video signal on/from a magnetic tape has a delay for delaying a composite sync (synchronizing) signal obtained from a reproduced video signal: a signal adding circuit for adding a VITC (vertical interval time code) signal to the delayed composite sync signal; a switch circuit for switching the mode of the apparatus between recording and reproducing modes; and a timing circuit. The composite sync signal is delayed by the delay, then the VITC signal is added thereto. The VITC-added composite sync signal is recorded for a predetermined horizontal scanning line(s) by switching the switch circuit. The delay is provided to maintain reception of the composite sync signal during the recording mode and to compensate delay in the loop from the reproducing circuitry to a circuitry for recording the VITC-added composite signal. Thus, the VITC signal can be written or rewritten over the recorded magnetic tape. A second apparatus also can overwrite the VITC signal by generation of a quasi-composite signal from the reproduced composite sync signal, having lead to the reproduced composite sync signal to compensate the circuit delay.

Abstract: A method is described for measuring the filling level of a liquid in a container using the radar principle, with the aid of a transmitting antenna which radiates a microwave signal in the direction of the liquid level and the base and is arranged above the liquid level, and with the aid of a receiving antenna which receives, inter alia, a measurement signal which is reflected on the liquid level and a base signal which is reflected on the base of the container, in the case of which method the actual base separation between the transmitting antenna and the receiving antenna and the base of the container is known, and in the case of which the dielectric constant and the permeability of the liquid in the container are at least approximately known. The method according to the invention is simple in terms of evaluation and leads to reliable results, to be precise, in that the actual filling level of the liquid in the container is determined at least approximately by calculation from the propagation time of the base signal, the actual base separation distance, the dielectric constant and the permeability of the liquid.
