  • Patent number: 10429150
    Abstract: An improvement to an optical assembly that is adapted to accept light from a field of view in front of the optical assembly and create a first inverted image on a first image plane. Further the assembly includes an objective lens, a first prism adapted to receive light from the objective lens and a second prism, adapted to receive light from the first prism and emit light. The improvement is the addition of a negative lens interposed between the first prism and the second prism, thereby reducing the total optical pathway of the optical assembly, relative to a device performing the same optical function and lacking the negative lens.

  • Patent number: 9753483
    Abstract: A click knob assembly that has a fixture having a circular inner surface defining uniformly spaced ridges separated by grooves and a knob, set in the fixture, and including a user accessible portion; a spring holder, attached to the user accessible portion; a spring assembly, engaged to the spring holder; and a first plunger and a second plunger engaged to the spring holder, each facing the circular inner surface, in opposed direction to each other, and each being pushed outwardly by the spring assembly, and thereby being pressed into the circular inner surface. The first plunger includes a click surface sized and positioned to engage the uniformly spaced grooves. When the knob is rotated, the click surface is pushed over a ridge, and then falls into a groove, making a click sound and both the plungers are maintained in contact to the circular inner surface by the spring assembly.

  • Patent number: 9046321
    Abstract: A rifle scope, comprising: a scope housing and an optical train, supported in the scope housing and defining an optical axis having a pointing direction. Also, a pointing angle adjustment electrical user input device includes a first button having a first position that does not cause the pointing angle to change, and a second position that causes a progressive change in the pointing angle over time in a first direction. The user input device also includes a second button, also having a first position and a second position and wherein placing the second button in the second position causes the pointing angle to change over time in a second direction opposite to the first direction. Finally, the rifle scope includes an electric actuator, adapted to change the pointing direction, responsive to the user input device.

  • Publication number: 20140290113
    Abstract: A rifle scope that includes an optical train defining an optical axis having a pointing direction. The optical train has an erector tube pivotably mounted in the scope housing and having a front end. The scope also includes an elevation and windage angle adjustment assembly, including a user input; an actuator assembly that changes the optical axis pointing direction in response to input from the user input, by pivoting the erector tube; a sensing and computing assembly that includes a laser assembly that produces a laser beam that is directed through the erector tube, a mirror that reflects the laser beam to a two-axis positioning sensor, and a data processor that computes the optical axis pointing direction in response to input from the two-axis positioning sensor; and an ocular display assembly, that displays the optical axis pointing direction as an image superimposed on the image of the field of view.

  • Publication number: 20140118821
    Abstract: A method of making a rifle scope that utilizes a mounting assembly that includes a longitudinal base plate and a mating, closure housing piece. Separate optical assemblies are attached to the base plate to form an optical train of optical assemblies, extending longitudinally along the base plate, to form an image magnifying assembly. Also, at least some of the optical assemblies include a support and an optical element and an adjustment feature permitting adjustment of position of the optical element relative to the base plate. In the method, at least one of the adjustment features is used to adjust position of one of the optical elements, relative to the base plate, and wherein the optical element is then permanently fixed in place. Finally, the mating, closure housing piece is attached to the longitudinal base plate and the closure housing piece is fastened to the base, thereby forming a rifle scope.

  • Patent number: 8584394
    Abstract: A rifle scope having a longitudinal dimension and a reticle and having an adjustment mechanism for changing the apparent reticle position seen through the scope, relative to a straight line extending along the longitudinal dimension of the scope. The scope includes an objective assembly defining an objective center line extending from the center of the assembly front to the center of the assembly back. Also, a housing includes an outer objective housing, and a tubular housing. An optical train is supported inside the tubular housing defining a train center line extending longitudinally through the center of the optical train. The objective assembly is mounted in the outer objective housing so as to have freedom to be repositioned, thereby changing the position of the assembly center line relative to the train center line and an actuation mechanism is adapted to reposition the objective assembly, in response to manipulation of the actuator.
