摘要:
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.

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.

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.

摘要:
The present invention provides a picture frame for displaying digital images taken by a digital camera. The invention may be a wall mounted frame or a desk top frame. The invention includes a display, such as an active matrix display for rendering images for viewing. The invention includes an interface for manipulating images by using a graphical user interface in conjunction with an operating system. The present invention may be employed for displaying overhead projection slides for conferences, lectures and meetings. The invention includes sensors for monitoring conditions in areas around the frame. The frame includes floppy disk and CD/DVD drives for transferring data to a memory of the frame. The memory of the frame is used to store images and may select images according to a program or list.
