Abstract: Multistatic radar systems and associated methods are disclosed herein. In some embodiments, a multistatic radar system can include multiple radar transmitters and multiple radar receivers. The transmitters are configured to generate radio-frequency (RF) signals in a target volume, and the receivers are configured to receive the RF signals after the RF signals are reflected off an object moving through the target volume. The transmitters and the receivers can be spaced apart and aperiodically positioned about the target volume. The receivers can sample and digitize the reflected RF signals at an RF frequency. The radar system further includes a processing device configured to determine a property of the object based on the sampled reflected RF signals.

Abstract: Provided is a device for facilitating babies learning to crawl. The device includes a padded U-shaped frame and a set of wheels attached thereunder. The U-shaped frame includes a set of stabilizing rods at opposite ends to prevent a baby from falling to one side while using the device. The U-shaped frame also includes a strap assembly adapted to fasten around the baby's waist. The strap assembly comprises a fabric strap and a fastener to hold the baby in place on the padding disposed on the inner surface of the U-shaped frame. The wheels allow the baby to move across a surface while the baby simulates a crawling motion. The present device facilitates babies in developing coordination and balance while helping them to crawl.

Abstract: A rotatable cantilevered gun rest (10) capable of being mounted upon a fixed support such as a wall in a hunting blind. The gun rest (10) can be rotated 180° to allow for sighting along any horizontal angle with respect to the wall. A proximal yoke (50) and a distal yoke (70) are used to support the gun. The distal yoke (70) is vertically adjustable to provide variable vertical sighting angles.

Abstract: Automation of retrieval of stored graphs in a multi-user system having a central processing facility with processes that create and translate graphical representation into varying levels of readable expression. The created, translated representations are stored in system storage in the form of graph files. The invention is expressed as a method that tabularizes stored graph files by table entries, each identifying a specific graph and including a listing of the corresponding graph files produced for the graph. When a user of the system identifies a graph by table entry and specifies a machine output or modification function to be performed on the identified graph, the tabularized entries are searched to locate an entry for the identified graph.
