Abstract:
A safety system includes an electromagnet positioned in an area. A power controller is coupled to the electromagnet to supply power to the electromagnet in accordance with an event. A trigger mechanism configured to trigger the event when the area is traversed by a person with a weapon such that upon activation of the electromagnet a magnetic force is generated capable of attracting the weapon to make continued use difficult or impossible within the area.
Abstract:
A system and method for projecting an image with predetermined characteristics includes a projector configured to project light on a surface, and a photo sensor configured to analyze light reflected from the surface. A controller is configured to compare the reflected light with a selected characteristic. The controller is configured to control the projector to adjust the projected light such that the reflected light substantially matches the selected characteristic to make the surface appear to be of the selected characteristic.
Abstract:
A device for indicating appropriate social distancing includes the ability to project light (in various forms and in a various ways) onto the ground in a manner visible by the user and those around them. A boundary of the projected light can be set to an acceptable social distance and can include different colors to indicated varying social distances for varying levels of trusted individuals. Proximity sensors set to appropriate distancing requirements, along with the varying levels of trust can be implemented into multiple devices being used in a group setting.

Abstract:
A collision avoidance device includes a mobile device having a display screen. A proximity sensor is disposed on a side opposite the display screen. The proximity sensor is positioned to detect any obstacles present in a path of a user operating the display screen while moving. A warning device is powered by the mobile device to alert the user of any obstacles in the path.
Abstract:
An ocean plow device and accompanying method which incorporate a passive plow blade and a jetter tool working in conjunction with one another to lower drawbar and increase cable deployment speeds. In order to avoid cavitation due to sand dilation, in one embodiment of the plow device, the jetter tool includes nozzles oriented in a downward and backward direction relative to the plow device which creates a flow pattern to turbulently remove surface soil in front of the jetter tool in a rapid manner. The jetter tool is pivotally suspended from a point in front of the passive plow blade, such that the jetter will be free to find its own equilibrium position. That is, the pivotal mounting enables the jetter tool to rotate upward in harder soils and become fully extended in softer soils in order to reach the equilibrium position. The passive plow blade behind the jetter tool provides a constant burial depth for the cable and also provides protection from side loads encountered during deployment. By utilizing the jetter tool, the present invention avoids forces due to the effect of pore water by creating a slurry through the mixing of high flow rate water with sand, and forming a trench in which the passive tool can follow. In one embodiment of the invention the passive plow blade is backward raked so as to be capable of riding up and over the obstacles thereby providing snag clearing and obstacle avoidance features.
