Abstract: An optical imaging system includes five lens elements, the five lens elements being, in order from an object side to an image side: a first lens element having positive refractive power; a second lens element having negative refractive power; a third lens element having positive refractive power; a fourth lens element having positive refractive power; and a fifth lens element having negative refractive power.

Abstract: A system and method are provided for automatic identification, extraction, and validation of data pertaining to receiving entity events (REE). Feature (or attribute) values associated with web content are identified. The web content may contain news and features on current/past affairs. The identified feature values are considered by a rule-based or a machine-learned model and, based upon output of the model, a determination as to whether the set of data comprises a REE is made. If the determination is positive, then multiple data items are extracted from the set of data and, optionally, from other data from the source.
