Abstract: A method and apparatus for copyright protection for various recording media such as compact discs (CDs) uses a combination of symmetrical and asymmetrical data encryption to permit the player to handle either copy-protected or non-copy-protected media, in a manner that is extremely difficult to compromise. Coupled with the combination of encrypting methods, an Authenticating Signature is recorded on the media only when copy-protection is required. The nature of this Authenticating Signature is such that it will not be transferred to illicit copies made on CD recorders. When either an original protected or an original non-protected disk is played, the presence or absence of the Authenticating Signature causes the player to correctly decrypt the program data. All original CDs therefore play normally. When a copy of a non-protected CD is played, the absence of the Authenticating Signature also causes the player to correctly decrypt the program data. However, when a copy of a protected CD is played, the absence of the Authenticating Signature causes the player to generate false data which prohibits the disk from playing normally.

Abstract: The rail support sleeper comprises a block (2) of reinforced concrete (38) and a visco-elastic bedplate (8). The block upper face takes the rail and its lower face (6) supports the block on ballast. The bedplate covering the lower face acts as an intermediate support between the ballast and the block. The manufacturing procedure involves a visco-elastic plate (18) having the same dimensions as the bedplate is prefabricated. During this phase chippings (27) are regularly distributed and attached onto one face (20) of the plate. The block is made by moulding concrete in a mould and the prefabricated plate integrated with it to form the bedplate. During moulding the plate is placed so that its chipping face coincides with the block lower face so that the chippings are integrated into the concrete.

Abstract: A tapping fitting for a pipe, preferably a plastic pipe, includes a rotatable blade assembly (3) threaded within a sleeve (4) non-rotatably received within a housing (2) such that rotation of the blade assembly (3) causes it to cut a cylindrical slug from the pipe to which the housing (2) is attached. The opposite faces of the sleeve (4) are exposed to the fluid pressure within the pipe thereby producing a balance of forces substantially eliminating transverse creep. In addition, the attaching section (22) of the fitting is formed with a bore (21) which is engageable by a sealing ring (35) received around the rotatable blade assembly (3) and which is of sufficient length to accommodate any axial creep, thereby enabling the blade assembly (3) also to serve as a valve. <IMAGE>

Abstract: A data playback device which records, stores, and plays back actual patient oscillometric blood pressure data to create a more realistic NIBP simulation for testing of an NIBP monitor. The system is made up of two units, a computer and a converter. The converter has a Universal Asynchronous Receiver/Transmitter (UART) connected to the computer and 16-bit D/A and A/D converters connected to the input and output, respectively, of a blood pressure monitor. The A/D converter (308) senses cuff pressure (104) and sends the signal to the computer (310). The computer then calculates the pressure pulse data from the stored patient data (312,501) and sends it to the monitor via the D/A converter (502), where the pressure pulse data is converted to a voltage and electronically summed (504) with the pressure transducer signal output by the blood pressure monitor under test. Typically, the playback system reads the current cuff pressure (104) in the blood pressure monitor and "plays back" the oscillation complex from the data file whose average pressure is closest to the current cuff pressure. The oscillation complex is scaled to the proper amplitude using linear interpolation before it is summed into the cuff pressure channel. This process is repeated for each pressure level during the oscillometric blood pressure determination. During testing, the blood pressure monitor sees an oscillation envelope and oscillation complex shapes similar to the original data from a real patient. <IMAGE>

Abstract: A portable emission microscope for analyzing failures in an integrated circuit chip while the chip is contained within a wafer sorter. A base for the microscope is placed over an opening in the wafer sorter. A translational apparatus is attached to the base for lowering a charge coupled device camera into an opening in the wafer sorter. A compact housing containing microscope optics is coupled to the camera. Also, a flexible rubber boot is coupled to the microscope optics for shielding extraneous light from entering the camera. A vibration reducing apparatus is coupled to the microscope optics for preventing movement of the camera relative to the chip. The vibration reducing apparatus fits within the rubber boot and is a rigid, hollow cylinder having an adjustable length. The microscope optics view the chip through the cylinder. The cylinder is adjusted such that when the camera is lowered into position over the chip, the microscope optics are an appropriate distance from the chip, the cylinder presses against, and firmly contacts, the surface surrounding the chip, preventing movement of the camera relative to the chip, while the rubber boot resiliently conforms to the surface surrounding the chip. A illumination system selectively illuminates the chip with one of two illumination sources. A first illumination source is a fibre optic ring housed within the rubber boot. A second illumination source illuminates the integrated circuit through the microscope objective lens.
