Abstract: A system for printing a three-dimensional object is provided. The system can include at least one print head configured to receive a continuous fiber and at least partially encase the continuous fiber with a formation material to create a composite material. The at least one print bed can be configured to move in at least six different degrees of freedom. The system can also include at least one print bed comprising a printing surface onto which the composite material may be selectively applied to form a work piece. The at least one print head can be positioned relative to the at least one print bed and configured to advance print media thereon.

Abstract: Training devices and methods are disclosed herein for training animals on a lead against excessive pulling by delivery escalating stimuli to the animal. The training devices described herein are coupled to a collar and include a housing with portions that can be moved toward one another against a force provided by a biasing device, such that when the collar is pulled against the neck of the animal, the compression of the training device between the collar and the neck of the animal causes the housing portions to move together. This configuration can be utilized to determine an amount of force imparted to a lead by an animal and/or to expose electrodes of a shock assembly.

Abstract: Methods are provided for determining the position of a substrate. The edge diffraction model suitable for the proposed measurement apparatus was mathematically derived, and the effect of the parameters associated with the edge diffraction was investigated. In addition, the fundamental limits are discussed about the linearity and resolution of the sensor by estimating the effects of edge roughness and sharpness of the knife edge on the knife edge diffraction of an incident wave based on Kirchhoff approximation.

Abstract: Methods for forming a piezoelectric device are provided. The method can comprise: electrically poling and printing the piezoelectric device from a polymeric filament simultaneously. The polymeric filament can comprise a polyvinylidene fluoride polymer (e.g., a ? phase polyvinylidene fluoride polymer, such as formed by simultaneously stretching and electric poling an electrically inactive ? phase polyvinylidene fluoride polymer).
