摘要： An optical system includes an aperture stop configured to direct light through the optical system, an inverting prism assembly configured to receive light from the aperture stop and direct light through the optical system, and a field stop configured to receive light from the inverting prism assembly and direct light through the optical system to an operator of the optical system. A point-of-impact is identified in object space and a point-of-aim is identified in afocal space of the optical system. The inverting prism assembly is configured to be pivoted about a center of the aperture stop to effect alignment of the point-of-impact and point-of-aim in the afocal space so that the point-of-aim is coincident with the optical axis.

摘要： A system and corresponding method for the concurrent operation of multiple radar systems on a common frequency and in the same geographical area includes a waveform generator that specifies certain operating parameters for the transmitted radar pulses. In a first instance, the carrier frequency can include an offset for each radar system. In a second instance, complementary codes can be used for the radar pulses such that each radar system operates with a unique code for substantially reducing the cross-talk between the radar systems. In another instance, both carrier frequency offset and complementary coded waveforms can be used to increase the number of radar systems that operate concurrently. Carrier frequency offset can also be used to combat range-wrap by using different carrier frequencies for adjacent radar pulses.

摘要： This invention relates to an adaptive detection system and method for analyzing range-doppler-azimuth data for target detection. The detection system has a threshold calculator for calculating a threshold value that is based on the standard deviation of the range-doppler-azimuth data and a predetermined probability of detection. The detection system also has a detection module in communication with the threshold calculator to receive the threshold value. The detection module calculates an estimated target amplitude and an estimated noise floor amplitude based on the range-doppler data that is located in a detection window. The detection module detects a target when the difference between the estimated target amplitude and the estimated noise floor amplitude is larger than the threshold value.

摘要： An apparatus includes one or more LEDs (304) configured to be coupled to a power supply (302) and to generate illumination, such as to generate a reticle (200) in an optical scope (104). The apparatus also includes a first switch (316) coupled in series with the one or more LEDs. The first switch is configured to selectively activate and deactivate the one or more LEDs based on whether the first switch is turned on or off. The apparatus further includes a low power detector (308) configured to sense a low power condition of the power supply and to repeatedly turn the first switch on and off in response to the low power condition to cause the one or more LEDs to blink. The low power detector is configured to turn the first switch on and off at a given rate, and the given rate increases as the power supply is depleted.

摘要： A tactile feel control device is disclosed. The tactile feel control device can include an electric motor configured to be mechanically coupled to a manual control interface that is movable by a user. The tactile feel control device can also include a bias module operable to generate a bias to be applied by the electric motor. The bias can be configured to provide a desired tactile feel to the user at the manual control interface. In addition, the tactile feel control device can include a control module operable to output a drive signal to the electric motor configured to apply the bias. The bias can be insufficient, alone, to cause movement of the manual control interface.

摘要： An apparatus (100) for rotary encoding includes a knob (102) configured to be rotated. The apparatus also includes multiple switches (304, 402) each configured to selectively form or not form a connection based on a current rotational position of the knob. The apparatus further includes a controller (312) configured to generate or use a digital value associated with the current rotational position of the knob. The digital value is defined by which switches have or have not formed connections. Locations where the switches form the connections are selected such that the digital values uniquely identify different rotational positions of the knob and are non-sequential as the knob is rotated.

The spectral generator further comprises a covariance matrix calculator that is in communication with the window generator to receive the range-doppler-sensor data within the window and calculate a covariance matrix estimate for a range-doppler cell of interest in the window. The spectral generator also includes a spectral calculator that is in communication with the covariance matrix calculator to calculate a high-resolution spectral vector based on a location matrix and a noise subspace matrix estimate.
