Abstract: Method and systems for generating vehicle motion planning model simulation scenarios are disclosed. The system receives a base simulation scenario with features of a scene through which a vehicle may travel. The system then generates an augmentation element with a simulated behavior for an object in the scene by: (i) accessing a data store in which behavior probabilities are mapped to object types to retrieve a set of behavior probabilities for the object; and (ii) applying a randomization function to the behavior probabilities to select the simulated behavior for the object. The system will add the augmentation element to the base simulation scenario at the interaction zone to yield an augmented simulation scenario. The system will then apply the augmented simulation scenario to an autonomous vehicle motion planning model to train the motion planning model.

Abstract: An apparatus for artificial intelligence (AI) bathymetry is disclosed. The apparatus includes a sonic unit attached to a boat, the sonic unit configured to generate a plurality of metric data as a function of a plurality of ultrasonic pulses and a plurality of return pulses. An image processing module is configured to generate a bathymetric image as a function of the plurality of metric data, identify, as a function of the bathymetric image, an underwater landmark, and register the bathymetric image to a map location as a function of the underwater landmark. A communication module is configured to transmit the registered bathymetric image to at least a computing device. An autonomous navigation module is configured to determine a heading for the boat as a function of a path datum and command boat control to navigate the boat as a function of the heading.

Abstract: Method and systems for generating vehicle motion planning model simulation scenarios are disclosed. The method receives a base simulation scenario with features of a scene through which a vehicle may travel, defines an interaction zone in the scene, generates an augmentation element that includes an object and a behavior for the object, and adds the augmentation element to the base simulation scenario at the interaction zone to yield an augmented simulation scenario. The augmented simulation scenario is applied to a vehicle motion planning model to train the model.

Abstract: The invention is directed to a secure data transmission system and method for use in connection with potentially untrusted computer systems and data communication networks. The method involves transmission of sensitive data, such as authentication credentials, between at least two entities (for example, client and server systems and zero or more trusted token systems). This method utilizes symmetric encryption, shared secrets, and data strings composed of pseudo-random characters (also known as “tokens”) to authenticate entities to other entities and to securely transmit data between entities.

Abstract: A dumbbell is described including a handle having a grip and at least one end, an inner plate mounted on the handle adjacent the grip, in a fixed rotational orientation, a support plate rotationally mounted on the handle adjacent the inner plate, at least one collar rotationally mounted on the handle adjacent the support plate, and rotationally fixed with the support plate, a selector knob rotationally mounted on the handle adjacent the at least one collar, and rotationally fixed with the collar, a weight plate removably mounted on the handle adjacent the at least one collar, and a means for selectively securing the support plate to the inner plate to resist the rotation of the support plate, collar and selector knob with respect to the inner plate and handle.

Abstract: The exercise devices disclosed herein are configurable to allow a user to perform various exercises. The exercise device can include an adjustable bench assembly connected with a frame supporting a cable-pulley assembly providing a user interface with a resistance system. A user can interface with an actuation component to pull resistance cables against resistance from the resistance system. Various exercise accessories can be provided that are easily connected with and removed from the exercise device to allow a user to perform different exercises. Some examples of exercise accessories are used to configure the exercise device for squat, abdominal, leg extension, leg curl, and arm curl exercises. The frame can also be configured to selectively place the exercise device in a stationary operating configuration supported by the frame on a support surface and a storage configuration wherein the exercise device is rollingly supported on the support surface by wheels.

Abstract: An exercise apparatus comprises a frame defining a front portion and at least one front wheel operably coupled with the front portion of the frame. The exercise apparatus also comprises an elevation support frame defining a front portion and a rear portion. The front portion is pivotally supported at the front portion of the frame and the rear portion operably supports at least one rear wheel. The exercise apparatus further comprises a motor coupled with the elevation support frame, the motor adapted to pivot the elevation support frame and extend the at least one rear wheel away from the frame.

Abstract: A coupling for hose comprises male and female members one of which carries a locking device for engaging a surface on the other member. The locking device is carried by a pair of opposed hinged arms and comprises a semi-circular unit containing an over-center, semi-circular aperture dimensioned to encompass a specific area on the other member.
