摘要： An analogue to digital converter circuit arrangement comprising: an input (24) to receive an analogue signal, a first sampling means (9) operating at a first sampling frequency and operative to generate at an output (23) a digital signal; and a DC correction feedback path (10a) connected between the output (23) and the input (24). The DC correction feedback path comprising in order between the output (23) and input (24) means (25) for integrating said signal at the output (23), second sampling means (27) for sampling the integrated signal at a second sampling frequency which is a much lower frequency than said first sampling frequency, a digital to analogue converter (29) and means (31) for subtracting from the analogue signal received at the input (24) the analogue signal at the output of the digital to analogue converter.

摘要： A laser marker system for marking indicia onto a substrate (146) includes an exit lens (140) having a focal length and a single laser source (120). The surface of the substrate (146) to be marked is positioned generally at the focal plane of the lens (140). The single laser source (120) is arranged so that its energy output beams are oriented in a generally parallel relationship. The single laser source includes segmented reflecting means (131) for generating a plurality of output energy beams (139) to create a column of spots on the substrate (146) with a higher resolution. The segmented reflecting means (131) is comprised of a back-reflecting mirror which is formed of a plurality of different mirror segments (131a-131n). A device is provided for moving each of the plurality of different mirror segments between a lasing position (148) and a non-lasing position (150) to vary the number of output energy beams and thus the number of spots on the substrate (146).

摘要： A document handling system, such as a mailing machine (10), includes a feeder station (24) operative to feed documents (26) from a stack in sequential fashion to a conveyor belt (36) of a transport station. The feeder and transport stations include discrete drive motor controllers (60, 61) operatively associated with a speed control (50) adapted to apply a control signal to the transport controller (52) and a control signal to the feeder controller (54). The feeder controller signal is slaved to the transport controller signal so as to enable changes in document feeder and transport speeds through a single control (64a). A separate gap control (76a) enables selective adjustment of the gap between successive documents for various size documents.

摘要： This invention relates to a control system for controlling movement of a member moveable between two limit positions by means operable by an electric motor. The control system in- dudes means to determine successive positions of said member during movement thereof between said limit positions, each of said successive positions representing a distance from one of said limit positions and monitoring means for monitoring current used by the motor when said member is at each of said successive positions. The system further includes a memory in which is stored a table for a) values of monitored current taken during the preceding operation of said member or values representing average of monitored current values taken during at least two preceding operations of said member and b) successive positions at which said values of monitored current are taken. The monitored current value for a given position taken during the current operation is compared to the corresponding monitored current value in said table for the same given position and when the monitored current value exceeds the corresponding current value taken from the table, the motor is cut off to stop movement of the member. The monitored current values taken during the current operation are used to update the table in said memory.

摘要： A polarisation controller comprises at least one stack of nematic liquid crystal cells (1, 3) arranged such that radiation (101) incident on the stack will pass through each cell in the stack in sequence. Synchronised electric or magnetic fields are applied across the cells so as to change the phase retardation of the radiation transmitted through each cell by a chosen amount, the optical axes (5, 7) of the cells being oriented with respect to each other such that the polarisation of radiation incident on the controller is caused by the controller to change from a first state to a second state.
