A multiple probe acquisition system, such as for use with a value instrument, uses probes where each probe includes an acquisition circuit for acquiring from a circuit under test an electrical signal as digital data at a high rate, and then transferring the digital data from the probe to the instrument at a lower rate over a data bus for processing and display. The corresponding medical implant is produced from the titanium alloy using the investment casting process, thus allowing economical production of objects from \u03b2-titanium alloys. The fluid may be oil for lubricating components of the mechanism. The optical filter transmits a portion of the optical beam having a wavelength within a bandwidth of the optical filter. The bench seat has a bottom portion and a back portion and is configured to move from a front-facing position to a rear-facing position by moving the back portion toward a front of the passenger compartment for when the vehicle is operating in an autonomous mode.
