  • Publication number: 20220357724
    Abstract: An Industrial Internet of Things (IIoT) agent module or device preferably used as or in place of a Supervisory Control and Data Acquisition (SCADA) data node system and/or conventional SCADA system, which is operatively coupled and in communication with an IIoT cloud platform, so as to perform control and data acquisition operations and exchange data and commands automatically or in response to Inputs from the IIoT cloud platform; wherein all production details/settings/parameters, including process logic, control methodology, product recipe, and data point setup, can be dynamically changed based on decision/input/command of the IIoT cloud platform, such that the IIoT cloud platform might completely “re-configure/re-program” a software portion of the IIoT agent module or device governing its working behavior or characteristics by sending a reconfiguration/reprogramming information.

  • Publication number: 20200367867
    Abstract: A balloon-anchored, biopsy device includes a first elongated tube, a second elongated tube, and a flexible biopsy needle. A section of the first elongated tube near the distal tip may include a balloon for insertion into a blood vessel that when inflated, anchors the section in the blood vessel near a biopsy site. The second elongated tube includes a beveled distal exit of a second lumen, which may be positioned at the biopsy site when the first elongated tube is anchored in the blood vessel by the inflated balloon. The flexible biopsy needle is configured to exit the beveled distal exit for penetration into tissue at the biopsy site at a predefined angle between a longitudinal axis of the section of the first elongated tube and a longitudinal axis of the flexible biopsy needle, and to acquire a biopsy sample of the target organ at the biopsy site.

  • Publication number: 20060255282
    Abstract: Semiconductor-based elements as an electrical signal generation media are utilized for the detection of neutrons. Such elements can be synthesized and used in the form of, for example, semiconductor dots, wires or pillars in the form of semiconductor substrates embedded in matrixes of high cross-section neutron converter materials that can emit charged particles upon interaction with neutrons. These charged particles in turn can generate electron-hole pairs and thus detectable electrical current and voltage in the semiconductor elements. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or the meaning of the claims.

  • Patent number: 7124207
    Abstract: A method and system for batching commands and status information between a host computer and an adapter installed on the host computer. The method for command batching includes the host storing command pointers, each command pointer pointing to a command in an array, and providing an array pointer to the array. When a predetermined threshold of stored commands has been reached, the host can deliver a multitude of commands via the array pointer with a single bus access. A method for status batching includes transferring command statuses from the adapter to the host computer and providing a pointer to the transferred statuses. When a predetermined threshold of statuses has been reached, the adapter interrupts the host computer once to fetch the pointer and the host can then read the statuses without requiring any more bus interrupts.
