International Classification:

E02D 29/14
E01C 5/00

US Classification:

404 25, 404 73

Abstract:

A supplemental access cover is adapted to cover an access cover. The supplemental access cover includes a layer of material having a thickness in the range of 0.01 inch to 1.5 inches, and an apparatus for attaching the layer of material to the access cover. A method for paving uses the supplemental access cover. The method includes locating an access cover within an area to be paved, attaching a supplemental cover to the access cover, and paving over the access cover and the supplemental cover. The method for paving also includes relocating the access cover, and removing the supplemental cover from the access cover.

International Classification:

F41J 5/24

US Classification:

273383

Abstract:

A remotely-perceptible, impact-indicating target for a projectile, such as a bullet or the like, constructed so as to remotely perceptibly indicate and annunciate very realistically, to a target shooter at a projectile shooting location, the impact of a shot or fired projectile or bullet on a remotely located target in a manner clearly visibly perceptibly indicating not only the hit, but the impact location of the projectile or bullet on the target, by causing the effective expansion in an explosion-simulating manner of a quantity of visibly perceptible target material.

US Classification:

623 111

Abstract:

Medical devices and methods for making and using medical devices are disclosed. An example medical device may include an elongate shaft including a first tubular member and a second tubular member. A balloon may be coupled to the shaft. A first member may be coupled to the first tubular member and positioned within the balloon. A second member may be coupled to the first tubular member and positioned within the balloon. A medical implant may be coupled to the shaft and positioned adjacent to the balloon.

International Classification:

A61B 1/32

US Classification:

600205

Abstract:

A portal access device has a first member pivotally movable relative to a base. A groove is provided at the first member to be in alignment with a bore at the base, so that a cannula may freely extend through the bore, with a portion of the cannula being frictionally held along the groove of the first member. The first member may be rotatably connected to a second member, so that once the cannula is correctly inserted into a portal, the first member may be pivoted from its vertical position to its horizontal position to bend the cannula into a right angle cannula. The cannula is removed from the portal by pivoting the second member upwardly away from the base. In an alternate portal access device where there is only one arm member, the portal access device may be removed from the portal by being pulled vertically upwards.

International Classification:

G06N 3/10
G06F 17/16
G06F 17/11
G06N 3/04

Abstract:

Aspects discussed herein may relate to methods and techniques for embedding constrained and unconstrained optimization programs as layers in a neural network architecture. Systems are provided that implement a method of solving a particular optimization problem by a neural network architecture. Prior systems required use of external software to pre-solve optimization programs so that previously determined parameters could be used as fixed input in the neural network architecture. Aspects described herein may transform the structure of common optimization problems/programs into forms suitable for use in a neural network. This transformation may be invertible, allowing the system to learn the solution to the optimization program using gradient descent techniques via backpropagation of errors through the neural network architecture. Thus these optimization layers may be solved via operation of the neural network itself.

International Classification:

G06N 3/04
G06N 3/08

Abstract:

Aspects described herein may allow for the application of stochastic gradient boosting techniques to the training of deep neural networks by disallowing gradient back propagation from examples that are correctly classified by the neural network model while still keeping correctly classified examples in the gradient averaging. Removing the gradient contribution from correctly classified examples may regularize the deep neural network and prevent the model from overfitting. Further aspects described herein may provide for scheduled boosting during the training of the deep neural network model conditioned on a mini-batch accuracy and/or a number of training iterations. The model training process may start un-boosted, using maximum likelihood objectives or another first loss function. Once a threshold mini-batch accuracy and/or number of iterations are reached, the model training process may begin using boosting by disallowing gradient back propagation from correctly classified examples while continue to average over all mini-batch examples.
