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.

Multi-Functional Optical Disk Drive
a method for utilizing the mechanism for two
different standard types of optical disks.
shows an example of this apparatus. The
beam (1) from the optical head (1) which contains a light source and
sensors goes to the prism (2). Prism (2)
divides the beam into two
directions (3,4). Each beam (3,4) goes
to each objective lens (5,6)
and focuses on each disk (7,8). These
disks (7,8) are rotated by a
single spindle motor (9). This spindle
motor (9) can attach
different types of hubs (10,11) at each end of its spinning shaft in
order to mount different types of optical disks (7,8), such as the
hole hub type or magnetic hub type.
Objective lenses (5,6) are
mounted to the same moving part (12) of the actuator which can focus
and track the disk. These lenses (5,6)
can be utilized to different
optical types of optical disks, such as the difference in the
thickness of the disk.
mechanism, this method can obtain multi-functional
optical disk drive.
