Abstract:
A device includes can be supported on a weapon, and has a range portion (156) that specifies a range to a target, a sensor portion (201) that provides sensor information representing an orientation of the device; and a sight (10) that facilitates weapon orientation in preparation to fire the munition. The device has an electronic control portion (216) responsive to sensor information from the sensor portion (201) and a range from the range portion (156) for calculating how to hit a target with a munition, and for causing the sight (40) to present a visual indication of how to orient the weapon so that the munition will hit the target, the electronic control portion (216) terminating the presentation of the visual indication by the sight (10) in response to a lack of user activity for a selected time interval during the presentation of the visual indication.
Abstract:
An electronic eyepiece includes a digital microdisplay and an electrically switchable light blocking mechanism configured to selectively transmit or block light transmitted along an optical path toward the digital microdisplay.
Abstract:
An apparatus has a rangefinder portion that includes: a radiation generator which emits radiation having a selected wavelength; a radiation detector which detects radiation having the selected wavelength; and an optical portion which includes a non-reciprocal optical part. The optical portion routes radiation emitted by the radiation generator at the selected wavelength through the non-reciprocal optical part and then through an aperture toward a location remote from the apparatus, and also routes radiation received via the aperture at the selected wavelength through the non-reciprocal optical part and then to the radiation detector.
