Abstract:
An electronic acceleration switch, such as for arming and firing a squib, for instance used in arming a warhead, safe missile air, ground and sea launch separation arming, includes multiple redundancies to provide a fail-safe system that does not have a single-point failure. The switch includes different channels, each of which includes a power subsystem, multiple accelerometers, a pair of controllers, and a switching circuit. The power subsystems of the two channels provide power to multiple accelerometers of each channel. The accelerometers of each channel may include a mix of digital and analog accelerometers. The acceleration sensors can be either one-axis or three-axis sensors. The accelerometers are connected to the controllers of both channels. The controllers provide redundancy for each channel. In addition, the controllers include voting logic that receives inputs from the accelerometers, and determines whether to send arm and enable signals to the multiple squib drivers.

Abstract:
A system includes an interface with a plurality of sub-addresses. The interface receives critical data and non-critical data. The critical data are received only at more specific sub-addresses of the interface. The interface transfers the critical data received at the sub-addresses to a critical processor, such that the critical data avoids being received by or being processed by a non-critical processor. The interface transfers the non-critical data from the interface to the non-critical processor. The configuration of the interface is hard-coded such that the configuration of the interface is fixed at power up of the interface and is non-changeable by the non-critical processor. The interface includes an external platform interface that is external to the critical processor, the non-critical processor, and a local controller. The external platform interface includes a limited ability to store the critical and non-critical data.

Abstract:
A releasable ball lock hinge is disclosed. The releasable ball lock hinge includes a first body operable with a hinge ball and a release ball. Each ball can be movable within respective openings of the first body. The releasable ball lock hinge also includes a second body configured to rotatably interface and removably couple with the first body. The hinge ball releasably engages the second body. The second body has a release recess operable with the release ball to disengage the hinge ball and alternately couple and release the first body and the second body based on a relative position between the first body and the second body.

Abstract:
An optical imaging system and method in which a second channel is used to provide alignment data for achieving image frame stacking of image data in a first channel. In one example, image stacking of infrared images is achieved by obtaining and analyzing corresponding visible images to provide alignment data that is then used to align and stack the infrared images.
If you've got this one ship, then you've sort of created another problem where you need to fill it, explains technical director David Robillard. So, how do you fill those empty moments? [...] Well, we created this Intensity Director, which is more than just an AI spawner. It creates moments for y
