Patent AU-1222701-A (AU)
Title: Method, apparatus and system for high-speed transmission on fiber optic channel
Inventor: AGAZZI OSCAR E
IPC: H04L27/26
Filed: 2000-10-20
Abstract: Multi-carrier modulation fiber optic systems constructed using a series of electrical carriers, modulating the data (201) on the electrical carriers (207, 215, 221) and combining the carriers to form a wideband signal (211). The wideband signal can then be intensity modulated on a laser and coupled to a fiber optic channel (213). A receiver may then receive the laser signal from the fiber optic channel and convert it into an electrical signal (301, 325). Multi-carrier modulation may be applied to existing fiber channels, which may be of lower quality. Existing fiber channels may have characteristics which prevent or restrict the transmission of data using intensity modulation at certain frequencies (601). An adaptive multi-carrier modulation transmitter (725) may characterize an existing fiber optic channel and ascertain the overall characteristics of the channel. The transmitter and receiver (825) can then be configured to use various bandwidths and various modulations in order to match the transfer characteristic of the fiber channel (601). A series of adaptive multi-carrier modulation transmitters and receivers can be integrated on a single integrated circuit. If multiple adaptive receivers and transmitters are integrated on a single integrated circuit (917, 919), they may be used to upgrade existing networks by adding different wavelength lasers (903, 905, 907) for the transmission of data in order to achieve any capacity desired. Each receiver and transmitter may characterize the fiber for its particular wavelength laser and may configure the modulation and bandpass to the fiber's characteristics.

Title: Device for transmission of one-way torque
Inventor: HODSON PETER DAVID
IPC: A61M15/00
Filed: 1994-11-21
Abstract: A device for the transmission of one-way torque comprising an outer annular member having a plurality of radially inwardly projecting teeth each comprising a driving surface and a cam surface, and a shaft concentrically mounted with respect to the outer annular member and comprising a plurality of drive elements each having a driving surface and a cam surface. Rotation of the shaft or outer annular member in its driving direction causes engagement of a driving surface of at least one drive element with a driving surface of at least one tooth thereby resulting in joint rotation of the shaft and outer annular member. Rotation of the shaft or outer annular member in its non-driving direction causes engagement of the cam surface of at least one drive element with the cam surface of at least one tooth resulting in additional relative movement, substantially radially, between the drive element and tooth, thereby preventing rotational movement being transmitted between the shaft and the outer annular member.
