The oil control device comprises an annular body (19) for rotation with said shaft (8) and includes a first face (30) extending generally radially from said axis. A second radially outer circumferential surface (40) is provided, extending generally axially. An oil slinging groove (32) extends into said body (19) and has a mouth (37) defined between a first circumferentially extending rim (38) and a second circumferentially extending rim (39). The second rim (39) is spaced both radially and axially from the first rim (38). The groove (32) is defined at least in part by a wall (34) which meets the first rim (38) at an acute angle to a radial plane. The groove (32) is also defined at least in part by a wall (35) which meets the second rim (39) at an acute angle to the direction of the axis.

摘要： A data rate determination apparatus includes an edge detection and clock generation circuit for receiving an input bit stream. The edge detection and clock generation circuit generates a pulse for each edge detected in the input bit stream. The pulses are passed to a programmable re-triggerable monostable multivibrator circuit coupled to a binary counter, which counts how many pulses are received within a time period determined by the number of pulses received at a rate higher than a predetermined rate. The binary counter is coupled to a Gray code counter coupled to a processing unit. The processing unit uses different counts that are accumulated over different sampling periods with different predetermined rates to establish statistical data, which can be compared to known data for different data rate standards or formats.

摘要： Inter-Symbol Interference is measured in fibre-optic communications systems by using the statistically balanced nature of the data being communicated and correlating a received data signal with a time-delayed version of the data signal to obtain an error signal. The error signal drives an adaptive equaliser to achieve channel equalisation.

摘要： In the field of optical communications, a number of techniques are known for channel equalisation. However, these techniques are, for various different technical and/or economic reasons, unsuitable for application in relation to optical communications at a data rate of 10 Gbps. Consequently, the present invention provides a dithered linear search algorithm adapted to change tap weights (45, 75) of a filter (15) in accordance with a heuristic tap modification scheme.
摘要翻译：在光通信领域中，众所周知的是用于信道均衡的技术。然而，由于各种不同的技术和/或经济原因，这些技术不适合以10Gbps的数据速率与光通信相关的应用。因此，本发明提供一种抖动线性搜索算法，其适于根据启发式抽头修改方案来改变滤波器（15）的抽头权重（45,75）。
