Concept Search - What can I type?
For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.
Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Automotive Safety System
In the existing art, some have proposed coupling impact sensors to a cars hazard lights. However, we note that operating lights is useful only if the car is spotted, and if the hazard lights are not damaged.
Also existing is systems that have built-in transmission mechanisms coupled to impact sensors. However, this increases the cost of the car, and creates a failure point, the transmitter, which might be damaged in a collision.
We disclose a mechanism that improves automotive safety by coupling impact sensors to off-the-shelf transmission devices such as cellular telephone. When a driver or passenger enters the car carrying a transmission device, the device creates a link with the cars sensors. Impact sensors can include security sensors and/or airbag deployment sensors.
Communication devices can include, but are not limited to, cellular telephones, satellite transmitters (eg., some radios includes an uplink), and walkie-talkies. When these devices enter the cars perimeter, they couple with the impact sensors. Couplings include wire-attachment and short-range radio such as 802.11b.
When the sensors detect a collision, the distress signal is transmitted from the sensor to the communications link via the coupling, then to a monitoring station responsible for initiating an appropriate reaction.
