An improved rearview mirror for use on most types of motor vehicles (cars and trucks) includes two plane (flat) reflective surfaces held at an acute angle with respect to each other. One of these a principal reflecting surface used as the principal rearview mirror; and a second reflecting surface being oriented so as to provide a reflected image of traffic in the blind spot of the principal reflecting surface. This second reflecting surface called the blind-spot-mirror. A support structure holds the principle reflecting surface bound to the larger reflecting surface, the blind-spot-mirror. Although the blind-spot mirror is larger, only portions of it appear to the driver as it is mostly covered by the principal reflecting surface. The support structure between the two reflective surfaces has the shape of a wedge (one or more) necessary for maintaining the blind-spot-mirror at the proper angle so as to reflect blind-spot traffic to the eye of the driver. It is useful on close-to-the-street or high-above-the-street vehicles.

Several digital sensing devices are described for use in automated production systems. The first described is for use in the automatic operation of a reactor. This device employs a binant electrometer using a quartz fiber mounted at one end but free to vibrate at the other in an AC field. The fiber oscillates if a charge is placed upon it. An optical slit replaces the ordinary eyepiece reticule scale. With the quartz fiber adjusted so its image is in focus at the optical slit, photoelectric signals are obtained at null charge on the fiber. The quartz fiber is repeatedly charged and allowed to discharge by collecting ions from a source under measurement. Each photoelectric signal causes a digital time reading to be taken. The time readings are used to evaluate the current due to the collected charge. The photoelectric signals, by feedback, also operate the electrometer for continuous or intermittent-continuous operation.

An optical measuring system is described for automatically operating an electrometer. A binant electrometer is employed with a quartz fiber mounted at one end but free to vibrate at the other in an AC field. The fiber oscillates if a charge is placed upon it.

With the quartz fiber adjusted so its image is in focus at the optical slit, photoelectric signals are obtained at null charge on the fiber.

The time readings are used to evaluate the current due to the collected charge. The photoelectric signals, by feedback, also operate the electrometer for continuous or intermittent-continuous operation. Basically the system is a current digitizer.
