  • Publication number: 20200234915
    Abstract: Disclosed herein is a method comprising: depositing a first amount of electric charges into a region of a sample, during a first time period; depositing a second amount of electric charges into the region, during a second time period; while scanning a probe spot generated on the sample by a beam of charged particles, recording from the probe spot signals representing interactions of the beam of charged particles and the sample; wherein an average rate of deposition during the first time period and an average rate of deposition during the second time period are different.

  • Patent number: 7408944
    Abstract: A system, method, and apparatus for providing an embedded controller in a modem device for enabling data communication between different networks. Management and control capabilities for a gateway function are embedded into a communication controller of the modem device so as to enable direct connection between wired and wireless devices while eliminating a separate gateway controller. A single controller in the modem device, wired or wireless, manages its own designated communication functions and data exchange between the two different networks.

  • Patent number: 7349996
    Abstract: A system and method for enabling remote management of data of devices using wireless communications. The system and method provides direct access to devices such as sensors from wireless devices having an integrated wireless transceiver and controller that are user programmable such a separate remote host controller is not required for managing the sensors. In one embodiment, a broadcast mode is provided wherein the wireless devices transmits a response for its corresponding sensors according to a predetermined sequence during a predetermined time slot according to a predetermined sequence.
