A fluid distribution system includes a boost supply providing a fluid flow, and a fluid metering system downstream of the boost supply. The decay time for a unit fluid pressure pulse generated within the catheter is proportional to the catheter length, i. A second computing device then downloads the message storing the data representing the personal information item from the IMAP server and makes it available to a PIM program executing on the second computing device. The optical disk drive dynamically controls skew between the disk and the optical pickup so that light is incident on the disk in a precise direction, thereby increasing its performance of data recording and reproducing. In a programming mode of the chip, external programming voltages are provided for programming the off-system programmable nonvolatile memory, and in an operation mode of the chip, the pumping circuit produces internal programming voltages for the on-system programmable nonvolatile memory for programming the on-system programmable nonvolatile memory. For example, in MEG measurements the object associated with the transmitters is the head of a human being on whose surface the transmitters are placed.
