Abstract: A buoyant module comprising a base configured for being buoyantly supported within a body of water, wherein said base defines a space which is in fluid communication with said body of water; a fluid-holding container sized and fitted for being received within said space and for moving in a vertical dimension relative to said base; and wherein a vertical position of said container relative to said base is determined, at least in part, by a fluid level in said container.

Abstract: A method for copy protection includes receiving data in a recording module representing content to be recorded on a recording medium, the data including an indication that the content is to be protected from unauthorized copying. Responsive to the indication, the recording module signals a protection module to initiate a protection protocol in synchronization with the recording module. The protection module generates control information, so as to prevent the unauthorized copying of the content that is to be protected, and conveys the control information to the recording module, in accordance with the protocol. The recording module combines the control information with the data representing the content in the recording module, for recording on the recording medium.

Abstract: A method for protecting data recorded on an original data storage medium against unauthorized copying includes receiving data encoded in accordance with an applicable recording standard, and altering a portion of the encoded data such that the altered data are identified as erroneous according to the standard. The data are recorded on the medium, together with ancillary data which are used by a processor in an intended application of the medium to operate upon the altered portion of the data such that the application runs in a manner substantially unaffected by the alteration of the data. Upon unauthorized copying of the data, however, the ancillary data are ineffective in correcting the altered portion of the encoded data, so that the alteration causes a substantially unrecoverable error in an unauthorized copy of the original medium.

Abstract: A method for protecting data recorded on an original storage medium against unauthorized copying. The data are encoded in accordance with Standard 908 of the International Electrotechnical Commission. A portion of the encoded data is altered to introduce an error in a sub-code Q channel of the data, such that the altered data are inconsistent with Standard 908, but do not prevent playback of the data following recording thereof. The data, including the altered data, are recorded on the original storage medium, whereby an application which plays back the recorded data runs in a manner substantially unaffected by the alteration of the data, but a substantially unrecoverable error occurs in unauthorized copying of the original storage medium.

Abstract: A method for protecting data recorded on an original data storage medium against unauthorized copying includes receiving data encoded in accordance with an applicable recording standard, and altering a portion of the encoded data such that the altered data are identified as erroneous according to the standard. The data are recorded on the medium, together with ancillary data which are used by a processor in an intended application of the medium to operate upon the altered portion of the data such that the application runs in a manner substantially unaffected by the alteration of the data. Upon unauthorized copying of the data, however, the ancillary data are ineffective in correcting the altered portion of the encoded data, so that the alteration causes a substantially unrecoverable error in an unauthorized copy of the original medium.

Abstract: In a manufacturing process of a continuous linear velocity (CLV) storage medium, a method for rendering a file stored on the CLV storage medium immunized against an unauthorized duplication. The CLV includes a plurality of consecutive blocks, each including a data section and control section. The control section includes an error correction and an error detection code. The blocks are configured in a given format. The method includes the steps of: (a) modifying a portion of the data section in a block so as to constitute modified data section. The modified data constitutes reconfigured format which violates the given format. The method further includes the step of modifying the control section that is associated with the modified data section, such that the error correction and error detection codes match the modified data section.

Abstract: A method for recording audio data onto a compact disc so as to discourage unauthorized copying thereof, the method including sampling a source audio data stream to determine at least one source audio data portion thereof the a derivative function of a sequence of samples of the source audio data portion is substantially constant, modifying the source audio data stream by substituting the source audio data portion with a substitute audio data portion, recording the modified audio data stream into at least one frame of the compact disc the frame has a P-channel, and setting the value of the P-channel that corresponds to the substitute audio data portion to 1.

Abstract: A construction element, preferably a constructional toy, including a tubular body portion and, formed integrally with each of the opposite ends thereof, a pair of gripping jaws, each pair constituting a coupling portion. The constituent jaws of each pair are oppositely disposed with respect to a longitudinal axis of the body portion and are separated by oppositely disposed peripheral coupling device. The tubular body portion is formed with longitudinally directed, angularly spaced-apart, first coupling device. Each pair of the gripping jaws of the construction element can embrace a body portion of a second construction element, with the jaws not extending beyond a median plane of the body portion of the second construction element, and with inner surfaces of the pair of jaws conforming to the outer surface of said body portion.
