Abstract: The present disclosure includes a method of controlling a centrifuge for the centrifugal production of a milk product. The steps include taking a milk sample at an outlet of the centrifuge from a liquid phase, adding a substance to the milk sample that increases light transmittance of the milk sample, determining the light transmittance of the milk sample by transilluminating the milk sample using a light source and measuring light intensity via a photo cell, determining the fat content from a measurement of the light transmittance, and controlling the centrifuge as a function of the determination of the fat content. The present disclosure also includes a system for controlling the centrifuge.

Abstract: A system protects private information provided in an exchange between a client and a server. The system receives the private information from the client and determines whether it is of a type for which a guarantee may be issued. The guarantee provides an indemnity for the benefit of the client for misuse of the private information. The system then issues a guarantee for the private information, if it is determined to be of the type for which a guarantee may be issued, and provides the private information to the server with a guarantee.

Abstract: A system assures the accuracy of information and the performance of services provided by an entity. The system receives a request from the entity to bond the information and services provided by the entity and evaluates the accuracy of the information and the performance of the services. The system bonds the information when the information is determined to be accurate and the services when performance of the services is assured.

Abstract: A system for identifying a program stream being displayed at a receiver location comprises means at a central station for measuring the relative luminance of a plurality of predetermined areas in each frame and recording that data with their times of occurrence for each of a plurality of program streams as reference data, and means at a receiver location to measure the relative luminance of the same areas but at a repetition rate less than that at the central station for a given time after a channel change and thereafter at an even lower repetition rate and storing the measurements at the receiver location with times defining corresponding broadcast times, and means for transmitting the stored data to the central station for correlating the measured and reference data using the recorded times to access the corresponding measured values of the recorded and reference data.

Abstract: A steering mechanism for use on a pavement cutting machine or the like, the cutting machine having a pair of guide wheels which are coupled to the chassis of the machine through steering knuckles. The steering mechanism is operated by means of a fluidic actuator connected between the chassis and one of the steering knuckles. In order to insure that the guide wheels will turn together, the steering knuckles are interconnected by a pair of serially connected rods with the point of interconnection of the rods being the free end of a pivotal lever, the opposite end of the lever being connected to the chassis.

Abstract: A system and methods are disclosed for monitoring a home TV viewing system which may include a TV, a VCR and one or more cable converters. The system obtains information for identifying the source of video displayed or being recorded, i.e., off-air antenna, satellite antenna, cable converter tuner, VCR, personal computer, video game, etc. The system also obtains information identifying the video path of the video being displayed and/or recorded. The system "fingerprints" video recorded by the VCR so that the played back video may be identified as having been previously recorded. The system may record the date and time of recording and the video source of the video being recorded. The system includes probe/detector devices which obtain signals related to the frequency to which the TV, VCR, and cable converter are tuned, and a higher level processor which receives and processes those signals to identify channel tuning of the TV, VCR, and cable converter.

Abstract: A people monitoring system comprises a first unit (32) which receives data related to the number of people who are watching a television set, the unit being provided with switches (30) operable by such people to produce such data; and a second unit (33), remote from the first unit, which accepts and stores such data.

Abstract: In an apparatus comprising a combination of transmission means and storage means, the transmission means comprises (a) means for accepting data from people monitoring means which produces information relating to the number of people watching a television set and/or television channel detection means of a television viewing monitoring system; and (b) means for transmitting such data to the storage means, the storage means comprising a semiconductor data module (110) which is removable from the apparatus.

Abstract: An arrangement is disclosed which stores data received from a people monitoring unit which produces information relating to the number of people watching a television set and/or from a television channel detection unit of a television monitoring system. The arrangement transmits such data to a remote computer by means of a telephone line (87) of a public telephone network upon interrogation by the computer.

Abstract: A television channel detecting arrangement, for detecting to which channel a television set is tuned, comprises an inductive loop (14) for receiving a signal from a local oscillator (10) of the television set (12); a tuner (16); a detector (18,20) which are such that, when the tuner is tuned to the frequency of the signal from the local oscillator, a voltage is generated at the detector; and a counter (25) which addresses a store (24) which uses stored binary numbers to vary over a range the frequency to which the tuner is tuned.

Abstract: A transmission arrangement comprising a receiver (58) for accepting data from at least one of a people monitoring unit which produces information relating to the number of people watching a television set and a television channel detection unit of a television viewing monitoring system and a transmitter (T1, 53, 50, 52, 54, 56, S51, 60, 62, T2) for transmitting such data as a multibit digital word to a data storage device by way of a mains wiring system.
