Abstract: An interchange system includes a first carriageway, a second carriageway, a first ramp, a second ramp, a third ramp, a fourth ramp, a connecting deck, a first traffic weaving section, and a second traffic weaving section. The first ramp and the second ramp extend from a first portion of the first carriageway. The third ramp and the fourth ramp extend from a first portion of the second carriageway. The first ramp is elevated relative to the second ramp. The fourth ramp is elevated relative to the third ramp. The connecting deck connects the first ramp to the fourth ramp. The first traffic weaving section is defined between the first ramp and the connecting deck. The second traffic weaving section is defined between the fourth ramp and the connecting deck. A primary ramp extends from the first traffic weaving section; a secondary ramp extends from the second traffic weaving section.

Abstract: A system includes a processor to receive a first visual image and a second visual image associated with a first user of the first device and a second user of the second device. A first and a second visual identification parameter associated with the first user and the second user are extracted based on the first visual image and the second visual image. The processor receives a request from the first device for connection establishment with a visually accessible user of a device. The request includes a real time visual identification parameter associated with the user. The processor then identifies the user to be the second user when the real time visual identification parameter matches with the second visual identification parameter. A communication session is then established based on a successful confirmation of the match from the first device.

Abstract: A hand held fibrous duster is disclosed. The hand held fibrous duster comprises of a base and a cleaning fabric. The base defines at least one curved cleaning surface configured to hold a cleaning fabric thereon. The cleaning fabric is mounted on the cleaning surface and covers at least a portion of the cleaning surface such that on sliding the duster against a surface, only a fraction of the cleaning fabric comes in contact with the surface, said fraction defines a cleaning edge that remains in contact with the surface.
