    Abstract: A multi-zone capacitive force sensing apparatus/method is disclosed. In one embodiment, an apparatus includes one or more capacitors each having an upper conductive surface and a lower conductive surface substantially parallel to the upper conductive surface, a housing with a top plate and a bottom plate to encompass the capacitors, and a sensor in the housing to generate a measurement based on a change in a distance between the upper conductive surface and the lower conductive surface of each of the capacitors when a contact zone of the top plate associated with the each of the plurality of capacitors is deflected by a force applied on the contact zone. The apparatus may also include a comparison module associated with the sensor to generate a signal indicating unevenness of a force applied on the top plate when there is any significant difference between measurements of the capacitors.

  • Publication number: 20070096139
    Abstract: A semiconductor optical device is encapsulated by disposing the semiconductor optical device in a cavity defined by a cavity wall. The cavity wall is coated with a coating material having a first surface energy.

  • Patent number: 7143088
    Abstract: A dynamic-content web crawler is disclosed. These New Crawlers (NCs) are located at points between the server and user, and monitor content from said points, for example by proxying the web traffic or sniffing the traffic as it goes by. Web page content is recursively parsed into subcomponents. Sub-components are fingerpinted with a cyclic redundancy check code or other loss-full compression in order to be able to detect recurrence of the sub-component in subsequent pages. Those sub-components which persist in the web traffic, as measured by the frequency NCs (6) are defined as having substantive content of interest to data-mining applications. Where a substantive content sub-component is added to or removed from a web page, then this change is significant and is sent to a duplication filter (11) so that if multiple NCs (6) detect a change in a web page only one announcement of the changed URL will be broadcast to data-mining applications (8).
