  • Apparatus for detecting liquid level
    Patent number: 9983042
    Abstract: An embodiment of the invention provides a liquid-level sensor to detect liquid-level information of a liquid to be tested in a container. The sensor includes an electrode, a sensing circuit, an amplifier and a controller. The electrode is disposed on the outer surface of the container, comprising a first electrode and a second electrode. The sensing circuit is coupled to a first electrode and a second electrode, and receives a clock signal to generate a first voltage signal and a second voltage signal. The amplifier receives the first voltage signal and the second voltage signal to output an output voltage. The controller acquires liquid-level information of the liquid to be tested according to the output voltage and a voltage-volume table.
    Type: Grant

  • Non-blocking peripheral access architecture having a register configure to indicate a path selection for data transfer between a master, memory, and an I/O device
    Patent number: 5799207
    Abstract: A computer system is disclosed which has a master, such as a processor, a memory, and I/O device, a first transfer path, which includes a bus, and a second transfer path, which includes a transfer interconnection. Transfers between the memory and the I/O device are effected via the first path while transfers between the processor and the I/O device are transferred via the second path. The disparate treatment between these two types of transfers reduces the likelihood that the transfer via the second path is delayed and thereby reduces the likelihood that the master is totally blocked from operation.
