Patent SE-523353-C2 (SE)
Inventor: ANDERSSON OLA
IPC: H03M1/06
Filed: 2002-04-26
Abstract: The values X(n) input to a current-steering digital-to-analog converter (49) are modified (41) before the actual conversion to compensate for conversion errors of the digital-to-analog converter. The input values are modified according to a model (43) of the digital-to-analog converter in which each output value of the digital-to-analog converter Y(n) is a sum of a desired value directly proportional to the respective input value and an error. The error is a product of the settled output value, i.e. the difference between the desired value and the previous output value Y(n-1) actually provided by the digital-to-analog converter, and a relative step error that is a function only of the respective input signal and is stored in a table. The relative step error can be a function also of the previous output signal and of the previous input signal. This model has a low complexity and is suitable for on-chip implementation.

Abstract: A crusher includes a replaceable first crushing member having a first crusher surface and a replaceable second crushing member having a second crusher surface. The co-operation of the crusher surfaces is defined by at least one crusher setting parameter. From measurements of a quality parameter, which relates to the nature of the crushed material, on at least two different occasions during the service life of a set of replaceable first and second crushing members and on each occasion for at least two different settings of the crusher setting parameter, a control function can be determined that describes a value, of the at least one crusher setting parameter, which on a given occasion gives a crushed material the quality parameter of which is substantially optimal. The control function is utilized for the adjustment of the crusher setting parameter for a subsequent set of replaceable first and second crushing members in such a way that on a given occasion for the subsequent set of replaceable crushing members, a crushed material is also obtained, the quality parameter of which is substantially optimal.

Abstract: A method and an arrangement in a data network, comprising a centrally located master (M) and a number of slaves (S1-Sn) connected to the master via a bus (1-4), to control, from the master, the access of the slaves to the bus. When a slave has information to send, a first signal, which implies a request for permission to send (RTS1/RTS2.../RTSn), is transferred via the bus to the master. A scanning means (9, 10) in the master scans for first signals from the slaves only if no slave has a permission to send and, when a first signal is found, the scanning is stopped and a second signal, implying a permission to send (CTS1/CTS2.../CTSn), is transferred via a distribution means (11, 10) to the slave which has requested the permission to send. The second signal is transferred to the slave only as long as the first signal is transferred from the slave to the master. <IMAGE>

A delaying module (706) delays the symbol vectors (805) from the vector generator (704) by one symbol time before they reach a main receiver (707). The main receiver (707) detects in a second window (806) the symbol vectors (805) with the length of one symbol time. The main receiver (707) uses a device with a second window algorithm (808) in order to estimate the received symbol vectors (805) with reference taken to the previously estimated symbol vectors in the main receiver (705) and the provisional estimates of the symbol vectors (805) from the auxiliary receiver (705).
