Abstract: Subscriber databases having a high fluctuation in subscriber data require special strategies to ensure, on the one hand, the greatest possible utilisation of the existing storage space but, on the other hand, also to keep the access times as short as possible. According to the invention, it is proposed to map an arbitrary subset of an arbitrarily large set of subscriber data to virtual control elements to which storage areas of the database are allocated via logical control elements. These storage areas allocated in this manner are, in turn, subdivided into smaller sub-areas, so-called pages. Using a small configuration table, it is possible to find the storage space allocated to a subscriber identification with only a few search steps. The average number of search steps is 4 to 6 with a memory utilisation of 80%. <IMAGE>

Abstract: A beam scanning galvanometer (44) is disclosed which oscillates a mirror (60) in a non-resonant mode. The moving parts of the galvanometer are made with as small a moment of inertia as possible because the mirror is oscillated in a non-resonant mode. The galvanometer uses two sets of crossed leaf-springs (70) to support the mirror instead of bearings which are usually used in non-resonant galvanometers. Each of the sets of leaf-springs is formed of a single strip of cold rolled stainless steel. The springs are embedded in uniquely shaped cavities in a permanent magnet (62) that supports the mirror at a distance very close to an axis of rotation of the mirror. The mirror is specially shaped with beveled edges so that its moment of inertia is low and so that it can oscillate in very close proximity to a driving current coil (64) which surrounds the mirror supporting magnet. A magnetic position sensor (90) is used to detect an angular position of the mirror during operation of the galvanometer. A compensating system eliminates distorting magnetic field effects from a magnetic driving system from adversely influencing the magnetic position sensor. Signals from the magnetic position sensor are usable to provide accurate feedback information to a galvanometer driving system.

Abstract: Although data is transmitted with efficiency by an arithmetic encoding system, the number of carry control signals increases in proportion to the number of consecutive bits "1"  s  s or bytes X'FF's in a conventional system. In the present invention, an arithmetic encoder 302 detects the possibility of a carry generated during arithmetic coding operation being propagated beyond at least a predetermined number of consecutive bytes X'FF's in a supplied arithmetic code 315. When the propagation of the carry is impossible, a carry control signal is inserted into the first 2 bits of the byte other than X'FF' which occurs immediately after the consecutive bytes X'FF's so as to transmit the presence or absence of a carry. An arithmetic decoder 303 detects the continuation of at least a predetermined number of bytes X'FF's in the arithmetic code 315, and arithmetically decodes an output value YN316 on the basis of the predicted value MPS317 of the occurrence probability of the output value YN316 to be encoded and the region width Qe of the complementary predicted value LPS. Since the number of total bits of the inserted carry control signals is reduced by this "one -time 2 - bits insertion system", the total number of transmitted code bits is also reduced.

Abstract: Signal components of the luminance signal are delayed by a 90° phase by a first filter (1) and pass therethrough, where the closer the frequencies of the signal components to the upper limit frequency of the frequency bandwidth of the luminance signal, the less the signal components attenuated. The signal components also pass through a second filter (2), where the phase of the signal components do not change, the closer the frequencies of the signal components to the upper limit frequency of the frequency bandwidth, the less the signal components attenuated. The signal components that have a phase difference of 90° with respect to each other and that pass through each of the filters (1 and 2) undergo vector composition to generate a signal that has an amplitude which is the root of the sum of the squares of the two amplitudes. A signal that has the same phase as the signal component that passes through the second filter (2) and that has the same amplitude as the amplitude of the signal subjected to the vector composition is then generated. From this signal the signal component that passes through the second filter (2) is subtracted to generate the edge emphasis component. This edge emphasis component is added to the luminance signal to emphasize the edge of an image.

Abstract: A method and apparatus for automatically controlling the removal of electrical power from a data processing system in order to avoid the uncontrolled termination of operations within the system. Scheduled system on and off times are stored within memory (84) within the data processing system. At a predetermined time prior to each scheduled power off time (86), warning messages are automatically transmitted to all users within the system (88). Each user may then request the deferral or cancellation of a selected power off (92). In the absence of a cancellation request and after any requested deferral period (96) the system will automatically initiate and conclude termination operations such as "clean up" (100) or "back up" (104) operations. Thereafter, a determination is made to ensure that a scheduled system on time will not occur within a predetermined period following an attempted removal of electrical power (108) in order to ensure that sufficient time is available for a complete power down sequence. In one embodiment of the present invention, an additional user specified power off program may be selected to ensure that additional conditions are met prior to permitting power removal.

Filed: 1993-01-18
Abstract: For a digital information transmission system in which the channel impulse response is determined at the receiver end, it is proposed to derive the pulse response for signal sections with arbitrary symbol sequence from the cross correlation function of the symbol sequence with the corresponding signal section of the sampled received signal by means of correction elements which contain the secondary values of the autocorrelation function of the symbol sequence. An iterative determination supplies a particularly good estimate of the channel impulse response. Correction of the impulse response is advantageous for short symbol sequences.
