摘要:
A signal/vibration detecting technique employs a simple structure to identify a target optical fiber among many and carry out a bidirectional conversation through the target optical fiber. First ends of optical fibers (202A, 202B), one of which is a target optical fiber, are connected to an optical transceiver (201). Second ends of the optical fibers are connected to each other to form a loop. A local unit (203) is installed at the loop. The local unit vibrates the loop, and the optical transceiver emits lights so that the lights are oppositely propagated through the loop. The propagated lights are coupled together so that they interfere with each other. In the intensity of the interfering lights, a change corresponding to the vibration is detected to identify the target optical fiber. Once the target optical fiber is identified, it is used to carry out a conversation between the optical transceiver and the local unit.

A bicycle disc brake caliper is provided with a detachable cooling system that transfers heat away from the actuating fluid. Basically, the bicycle disc brake caliper has a housing and a piston unit, with a coolant member of the cooling system attached to the housing. The housing has a frame mounting member sized to be coupled to a portion of a bicycle frame. The piston unit is movably coupled to the housing between a release position, in which the piston unit is spaced from a brake disc mounted to a wheel of a bicycle, and a braking position, in which the piston unit engages the brake disc of the bicycle wheel. The coolant member has a coolant area for receiving coolant to create a coolant heat sink that transfers heat from the housing. The housing has an actuating passage in fluid communication with the piston unit to move the piston unit via an actuating fluid. In one embodiment, the cooling system includes a pump and a reservoir. In another embodiment, a coolant or water bottle is attached to the coolant member for manually adding coolant thereto. In another embodiment, the coolant member is filled with a high specific heat gel.

In a data communication adapter apparatus for a digital data communication connected between a signal transmission path for transmitting both receive data and transmit data, and a host processor unit for producing frame data to output the frame data therefrom, an internal host bus is newly employed in the data communication apparatus irrelevant to the employment of a CPU dedicated bus, and the transmission/reception data generated and interpreted by the host processor is transferred via the internal host bus, a bus interface, and a system data bus between a transmission memory or a reception memory and a buffer memory. Furthermore, a reception memory (host dedicated reception memory) for storing only the reception data to be interpreted by the host processor is separately provided with another reception memory (CPU dedicated reception memory) for storing only the reception data to be interpreted by a CPU, one reception data to be interpreted by the CPU is once transferred from the transmission/reception control unit to the CPU dedicated memory and thereafter read out via the CPU dedicated bus under the control of the CPU, and the other reception data to be interpreted by the host processor is one stored in the host dedicated reception memory and then read out via the internal host bus and bus interface under the control of the host processor.
