Abstract: This patent concerns novel technology for detecting backdoors of neural network, particularly deep neural network (DNN), classifiers. The backdoors are planted by suitably poisoning the training dataset, i.e., a data-poisoning attack. Once added to input samples from a source class (or source classes), the backdoor pattern causes the decision of the neural network to change to a target class. The backdoors under consideration are small in norm so as to be imperceptible to a human, but this does not limit their location, support or manner of incorporation. There may not be components (edges, nodes) of the DNN which are dedicated to achieving the backdoor function. Moreover, the training dataset used to learn the classifier may not be available.

Abstract: An electronic system for a firearm includes a power source, one or more electrical conductors electrically connected to receive power from the power source, and a plurality of electronic devices. Each electronic device has an electrical input configured to receive power from the one or more electrical conductors to power the electronic device. A communication device is configured for data communication across the one or more electrical conductors. In some embodiments data can be communicated at rates greater than 10 Mbps. Some embodiments utilize multi-frequency encoding, such as orthogonal frequency-division multiplexing. Some embodiments include a data communication device with a lower data communication rate and another data communication device with a higher data communication rate, and can selectively communicate through either data communication device.

Abstract: A packaging card for a tool comprising a fixed member and a movable member that is selectively movable relative to the fixed member includes a tool engaging region coupling the packaging card to the movable member such that movement of the movable member relative to the fixed member moves the card relative to the fixed member. The card also includes a deformation region that tears or deforms upon application of a separation force sufficient to remove the packaging card from the tool. Another packaging card for a tool having a housing with front and side apertures includes a front flange receivable in the front aperture of the tool, a side flange insertable into the side aperture, and a hook catchable on an interior of the housing to deter removal of the packaging card from the tool until sufficient force is applied to overcome a holding power of the hook.

Abstract: A hitch mounted tree carrier is configured to be secured to a motor vehicle and permits a user to transport a tree from a first location to a second location. The hitch mounted tree carrier includes an elongated member configured to be removably received by a motor vehicle hitch and a receptacle having a front portion and a rear portion, wherein the front portion is affixed to the elongated member. The hitch mounted tree carrier also includes: (i) a wedge positioned in the receptacle and configured to apply a first force on a first extent of a tree trunk, when the tree is in the process of being inserted into the receptacle, and (ii) a securement assembly extending into the receptacle and configured to apply a second force on a second extent of the tree trunk, when the tree is in an engaged state.

Abstract: Embodiments of the present invention concern detecting Test-Time Evasion (TTE) attacks on neural network, particularly deep neural network (DNN), classifiers. The manner of detection is similar to that used to detect backdoors of a classifier whose training dataset was poisoned. Given knowledge of the classifier itself, the adversary subtly (even imperceptibly) perturbs their input to the classifier at test time in order to cause the class decision to change from a source class to a target class. For example, an image of a person who is unauthorized to access a resource can be modified slightly so that the classifier decides the image is that of an authorized person. The detector is based on employing a method (similar to that used to detect backdoors in DNNs) to discover different such minimal perturbations for each in a set of clean (correctly classified) samples, to change the sample's ground-truth (source) class to every other (target) class.

Abstract: A brake or a clutch includes a central shaft, an output-side threaded driver, an output brake plate, an input brake plate, and an input-side threaded driver. The output-side threaded driver and the input-side threaded driver are rotationally locked to the central shaft, such as by splines. The output-side threaded driver is threaded to the output brake plate and the input-side threaded driver is threaded to the input brake plate. The output brake plate is threaded to the input brake plate in a direction opposite the threaded engagement of the drivers to the brake plates. The brake or clutch may include two stator plates and three friction discs located between the output brake plate and the input brake plate.

Abstract: In one aspect, a method for conducting a drop test of an article with one or more target parameters can include dropping the article and a drop carriage of a drop tower from an initial height with respect to a base of the drop tower for an initial drop test. The article can be coupled to the drop carriage. The method can include detecting accelerometer data with respect to the article for an initial impact between the drop carriage and the base of the drop tower; determining a constant energy balance curve; determining, based on the constant energy balance curve and a target pulse duration, a target complex stiffness and/or a target total weight; adjusting, based on the target complex stiffness or the target total weight, the complex stiffness and/or the total weight for a subsequent drop test; and conducting the subsequent drop test.

The at least one support section is coupled with the retainer housing with tab extending from the opening substantially perpendicularly to said front surface of the retainer housing. In some embodiments, a flap can selectively cover the tab section.

A shield member may be disposed within the interior volume and secured to one or more portions of the panel assembly, and the shield member may comprise a second material that is different than the first material. The shield member is adapted to protect a portion of the panel assembly when the vacuum cleaner bag assembly is disposed within the tank.

Abstract: This patent concerns novel technology for detecting backdoors in neural network, particularly deep neural network (DNN) classification or prediction/regression models. The backdoors are planted by suitably poisoning the training dataset, i.e., a data-poisoning attack. Once added to an input sample from a source class of the attack, the backdoor pattern causes the decision of the neural network to change to the attacker's target class in the case of classification, or causes the output of the network to significantly change in the case of prediction or regression. The backdoors under consideration are small in norm so as to be imperceptible to a human or otherwise innocuous/evasive, but this does not limit their location, support or manner of incorporation. There may not be components (edges, nodes) of the DNN which are specifically dedicated to achieving the backdoor function. Moreover, the training dataset used to learn the classifier or predictor/regressor may not be available.

Abstract: A vacuum cleaner bag assembly is adapted to be removably disposed within a tank of a vacuum cleaner, and the bag assembly includes a panel assembly made from a first material and forming an enclosure having an interior volume, and an aperture extends through the panel assembly. A shield member may be disposed within the interior volume and secured to one or more portions of the panel assembly, and the shield member may comprise a second material that is different than the first material. The first material may have a wicking barrier that inhibits wicking when the bag assembly becomes wet. The shield member is adapted to protect a portion of the panel assembly when the vacuum cleaner bag assembly is disposed within the tank and, together with the wicking barrier and a properly chosen first material, enhances performance of the vacuum bag assembly when wet.
