In a copying machine or a facsimile apparatus in which an original is scanned to read the information of the original, an original supporting table has caused the information side of the original to be opposed to a slit surface or the like. That is, the original has been placed on the original supporting table with the original surface thereof facing downwardly. A device is shown in which an original is placed on an original supporting table with the original surface thereof facing upwardly and ...

A new colorimeter blood analyzer having a capacity of simultaneously performing a specific blood test and reading the prothrombin time on a separate digital readout device. The program circuit module with appropriate calibration parameters which is self-referencing performs specific tests providing direct display of the desired blood constituent concentration. The analyzer provides an independent prothrombin well having a separate optical source for prothrombin time measurement providing direct ...

The invention concerns an improved retroreflectometer giving direct readings for measuring the value or degree of retroreflectivity, or visibility at night, of a paint applied to the surface of the road for marking ground signs, under conditions that simulate geometrically the real conditions of illumination and visibility of the sign from the driver of a vehicle. The value or degree of retroreflectivity is measured directly from the sample in question, making it unnecessary to have a sample for...

A book or magazine reading support including a rectangular back board with a forwardly extending shelf along the lower margin, and a pair of V-shaped brackets each having a long and a short arm diverging at an acute angle relative to one another. Each bracket has an open slot at the end of each arm. The reading support is optionally assembleable in high or low modes by interconnecting the slots of the long arms or the short arms respectively with the slots of the back board. A thin, clear monofi...

This invention provides an improved reading or viewing lamp that achieves extraordinary visual acuity when properly used. The lamp employs a quartz-halogen bulb together with a parabolic lens to provide a collimated beam. A light filter removes heat radiation and ultra violet radiation from the beam. A convex mirror reflects the filtered light beam to the reading or viewing area where because of the point source characteristic of the bulb and the remaining optics, the rays are substantially non-...

An integrated, multitrack, magnetic reading head in which a Hall effect or magneto-resistive material strip is deposited on a silicon substrate. The voltages produced in this strip are sampled by a group of amplifiers for the parallel-charging of a charge-coupled device, which is then read in series to obtain the output signal. Lateral tracks energize circuits making it possible by means of two resistive lines and a system of comparators to open the input gates of the charge-coupled device in or...

A remote meter reading arrangement in which power for the remote terminal is supplied from the data collection terminal by transmission lines. At the moment power is applied to the remote terminal, a clock pulse generator in the remote terminal is supplied with power and begins to generate clock pulses to a counter, which successively couples each stage of the meter to the data collection terminal so that pulses of greater or lesser amplitude are generated in sequence, corresponding to each sign...

An optical character reading system in which a sheet upon which characters or symbols are printed is illuminated and the characters scanned with a two-dimensional photoelectric sensor. Output signals from the sensors are processed to read the characters through right and left frame detecting circuits. The right and left frame detecting circuits detect white/black patterns of frames formed on the sensor when the left and right sides of the characters extend beyond the ends of the ranges of the se...

The present invention relates to an automatic meter reading transponder. The transponder is comprised of a receiver for receiving an external instruction and a transmitter for transmitting data. A CPU is connected to the receiver and the transmitter. A ROM is connected to the CPU and ROM contains a program for controlling the operation of the CPU. A real time clock is connected to the CPU for determining sequential predetermined time periods. Three input terminals are connected to the CPU for re...

The microfiche projector enlarges the image onto the flat white undersurface of the top panel of the enclosure which has a flat black interior. The viewer sees the image reflected in the adjustable 45.degree. mirror. The apparent image is about 50" in front of the user to reduce eye fatigue. The image is non-directional which allows considerable movement of the user.
