Abstract: A system for sensing the angular position of a code ring of magnetic matel which is rotatable about a cylindrical housing, also magnetic material, to any one of a predetermined number of code ring settings. Either or both the cylindrical housing and the code ring include permanent magnets to provide a magnetic circuit including both of these elements. The code ring has an inner surface which carries an N-bit digital code of magnetic material in N tracks. N Hall effect digital switches are disposed on the cylindrical housing adjacent the N tracks of digital code bits, respectively.

Abstract: A method apparatus for qualitatively detecting remnant magnetic fields in matched pairs of magnet cores. Equal magnitude and oppositely oriented magnetic flux is induced in the magnet cores by oppositely wound primary windings and current source. Identically wound secondary windings generate output voltages in response to the induced flux. The output voltages generated should be of equal magnitude and opposite polarity if there is no remnant field in the cores. The output voltages will be unequal which is detected if either core has a remnant field.

Abstract: A system (FIG. 1; FIGS. 18-19) performs addition or subtraction of packed, or binary-coded-decimal (BCD), values. Each BCD digit is stored in a nibble (500) of a register (400, 401). The least-significant bits (LSBs) (502) of corresponding nibbles of the registers are exclusive-ORed and results are stored in a third register (402) (FIG. 4 or 9). For addition, the registers' binary values are summed, six is added to each nibble of the sum using binary addition, and results are stored in one register (401) (FIG. 5). For subtraction, the registers' binary values are subtracted, and the results are stored in one register (401) (FIG. 10). The LSB of each nibble of the one register is compared with the corresponding exclusive-OR value from the third register (FIGS. 6 or 11).

Abstract: A confocal optical imaging system includes a laser for producing a linearly polarized beam which is transmitted through the optical elements of the system, focused on a small spot on the target, and reflected back through the optical elements to a photodetector where the reflectance from the spot is determined. The optical elements include a pinhole plate for restricting the size of the transmitted and reflected beams which plate, along with other of the optical elements, can produce unwanted reflections adding optical noise to the reflected beam from the target. A retardation plate between the pinhole plate and the target alters the polarization of the transmitted beam relative to the reflected beam so that a polarizer will discriminate between the true reflected beam signal and the unwanted reflections to thereby improve the signal-to-noise ratio at the photodete ctor.

Abstract: A glove or mitten includes a relatively thick insulating inner layer and an outer cover layer. The outer layer has an extra trigger finger receiving stall situated in front of the conventional trigger finger receiving stall. The single trigger finger receiving stall of the inner layer is received within the conventional trigger finger receiving stall of the outer layer. An opening, proximate the trigger finger receiving stall of the inner layer, permits the trigger finger of the wearer to extend through the inner layer and into the extra trigger finger receiving stall of the outer layer. Because the extra trigger finger receiving stall of the outer layer has no thick insulating inner layer therein, the trigger finger, when situated therein, can manipulate the trigger. Thus, the hand covering need not be removed to use the firearm. A waterproof, vapor permeable thin membrane intermediate layer may be provided.
