  • Patent number: 12440951
    Abstract: A spring tool for actuating explosive fasteners for driving nails into a substrate is disclosed. For the tool to operate at its maximum potential the firing pin guide should be pushed securely against the rear of the fastener and the tip of the fastener should be pushed securely against the substrate. The action of the operator pushing the tool forward to actuate the tool moves the trigger body forward while compressing the firing spring until the trigger body travels the exact distance needed to release the trigger ball. The trigger body must also be in optimal rotational orientation with the tool and means for accomplishing the alignment is disclosed.

  • Patent number: 12233296
    Abstract: A stand for a fire extinguisher comprises four identical panels and a square plate. Each panel has a rectangular portion and an isosceles trapezoid-shaped portion. The isosceles trapezoid-shaped portion has only two sides of equal length. The four identical panels are interconnected along their equal-length sides to form a truncated square pyramid having a rectangular box at its upper end. The square plate is mounted inside of the rectangular box parallel to a base of the pyramid to support a fire extinguisher.

  • Patent number: 10506966
    Abstract: Methods and systems relate to determining sensory motor performance based on user non-postural movements within a generated dynamic virtual environment. The generated environment requires users to: (i) utilize primary sensor inputs (e.g., vision, vestibular sensation and somatosensation); (ii) assess the dynamic virtual environment; and (iii) integrate and translate those inputs into movement to control the dynamic virtual environment. The methods may include receiving non-postural user input with respect to a state of one or more attributes of a dynamic virtual environment provided on a user interface for one or more sessions, the one or more attributes including a control object and a target which moves with respect to the control object; determining performance information based on the user input and the state of the one or more attributes for the one or more sessions; and determining sensory motor performance information from the performance information.

  • Patent number: 9727901
    Abstract: An image-based recommendation system provides a first set of selectable images to a user and receives user selections from the first set of images. If a user selects a single image from the first set of images, the product page associated with the selected image is transmitted to the user. If the user makes multiple selections from the first set of images, then the images associated with the user selections are analyzed and a second set of similar images is generated for transmission to the user. The process of receiving and analyzing user-selected images, generating image sets and transmission of generated images sets continues until the user selects a single image. The precision of identification of similar images can be improved by providing the user selections as training data to the image-based recommendation system.
