Abstract: The system according to the invention for detecting data spectrum distortion in transmission, in particular the distortion caused by selective fading, is based on identifying in-band dispersion, i.e an amplitude distortion and for this aim it substantially includes: two blocks (B₁,B₂) in parallel, the module behaviour of which have equal slopes but different signs upon a change of frequencies; two detectors of average power (R₁,R₂), each being associated to one of said blocks; and only one detected average power comparison means (A₀). 
     This system allows to detect the assymmetries of the data spectrum and by adding an AGC and a reference voltage, also the information related to the central notch is obtained. The distortion measurement obtained in this manner allows to generate a switching criterion or control, as countermeasure for selective fadings. 
     The criterion is obtained at intermediate frequency and generates an alarm whenever the distortions caused by fading evolve towards an error condition for the type of modulator-demodulator that is used. With reference to the "signature" drawn for a BER equal to 10⁻⁶ a curve (IF signature) is drawn representing the activation of an alarm whenever fading parameters exceed prefixed values. The IF signature is much more extended in frequency than the BER = 10⁻⁶ signature. Adaptive equalization is carried out at intermediate frequency on amplitude only, leaving group delay distortions unaltered.

Abstract: An X-ray testing apparatus for workpieces contains at least one linear arrangement of diodes which are sensitive to X-rays and are arranged at a very close spacing from one another. A high resolution is thereby obtained. If the, e.g., fibres to be tested extend in the same direction as the diode row and have a spacing that is smaller than the corresponding extent of the receiving surface of the diodes, an effective resolution is no longer possible. Consequently, the diode row is assigned a diaphragm whose width is smaller than the extent of the receiving surface transverse to the diaphragm slit. Furthermore, a switchover device is provided which enables specific diodes to be skipped during scanning of the diodes, in order to increase the scanning rate. <IMAGE>

Abstract: An apparatus and method for protecting BIOS stored on a direct access storage device (62) into a personal computer system (10). The personal computer system (JO) comprises a system processor (26), a system planar (24), a random access main memory (32), a read only memory (36), a protection means and at least one direct access storage device (62). The read only memory (36) includes a first portion of BIOS and data representing the type of system processor (26) and system planar (24) I/O configuration. The first portion of BIOS initializes the system (10) and the direct access storage device (62), and resets the protection means in order to read in a master boot record into the random access memory (32) from a protectable partition on the direct access storage device (62). The master boot record includes a data segment and an executable code segment. The data segment includes data representing system hardware and a system configuration which is supported by the master boot record. The first BIOS portion confirms the master boot record is compatible with the system hardware by verifying that the data from the data segment of the master boot record agrees with the system processor (26), system planar (24), and planar (24) I/O configuration. If the master boot record is compatible with the system hardware, the first BIOS portion vectors the system processor (26) to execute the executable code segment of the master boot record. The executable code segment confirms that the system configuration has not changed and loads in the remaining BIOS portion from the same protectable partition on the direct access storage device (62) into random access memory (32). The executable code segment then verifies the authenticity of the remaining BIOS portion and vectors the system processor (26) to begin executing the BIOS now in random access memory. BIOS, executing in random access memory (32), then activates the protection means to prevent further access to the protectable partition. BIOS boots up the operating system to begin operation of the personal computer system.

Abstract: In a space diversity receiver, matched filters (2) and a like number of channel estimators (3) are respectively coupled to diversity antennas to receive sequentially coded symbol sequences. A branch metric calculator (4) receives the outputs of the matched filters (2) and the estimates from the channel estimators (3) to calculate a branch metric of the received sequences for coupling to a maximum likelihood (ML) estimator. The branch metric is obtained by summing branch metric coefficients derived from channel estimates respectively with the output of the matched filters or by summing branch metric coefficients derived from a vector sum of channel estimates with the matched filter outputs. In another embodiment, adaptive channel estimators are provided for deriving channel estimates from received sequences and the output of an ML estimator. First branch metrics are derived from the received sequences and supplied to a branch metric quality estimator in which quality estimates of the channels are derived from the first branch metrics. An evaluation circuit evaluates the first branch metrics according to the quality estimates and produces a second branch metric for coupling to the ML estimator.

Abstract: Disclosed is an apparatus and method for allowing writable, magneto-optic (MO) data storage media to be defined as read-only. Because the MO media specification is compatible with WORM media, each sector of the media contains an error recovery section, called the defect management pointer (DMP) (312). In MO media, error recovery information is stored at a common location, so the DMP of each sector is used to indicate the state of the sector -- writable or read-only. A special data pattern is used to indicate whether the sector is blank or contains user data. With the DMP information set in the writable state (408), the sector can be written (410), however, the process of writing the sector also sets the DMP information to the data pattern that indicates that the sector is now in a read-only state. Once the storage state has been changed to the read-only state, the drive will no longer write data into this sector. The drive will also not allow the state to be changed from the read-only state back to the writable state. For data security purposes, data on media must sometimes be written over, or obliterated. After this process, the invention places a special pattern in the DMP, and thereafter, the drive can detect whether a sector contains user data, is blank, or has been obliterated (702, 704, 706, 708, 710, 712).
