  • Publication number: 20210314229
    Abstract: Techniques for grouping and labeling Internet of Things (IoT) devices are disclosed. A set of raw events associated with a first IoT device is identified. A context of the first IoT device is identified, and used to enrich at least some of the raw events. At least some of the raw events are aggregated. A context-based IoT device grouping model is generated based at least in part on the aggregated events and events associated with a second IoT device in operation. The model is applied to determine that a third IoT device belongs to a particular group. A deviation by the third IoT device from group behavior is detected and an alert is generated in response.

  • Patent number: 10908495
    Abstract: A photolithography process includes providing a first test layout including test patterns, and a first light source; forming an initial mask layout according to the first test layout; forming a mask layout including mask layout patterns through an optical proximity correction or a phase-shifting masking; forming exposed patterns by exposing the mask layout using the first light source; and determining a weak region from the first test layout. A first distance between adjacent test patterns in the weak region is unequal to a second distance between corresponding exposed patterns. The photolithography process further includes performing a re-layout on the weak region to increase the first distance, thereby providing an adjusted test layout; performing a light-source optimization to obtain an adjusted light source; and determining the adjusted test layout and the adjusted light source as a second test layout and a second light source, respectively when process window requirements are satisfied.

  • Publication number: 20200029300
    Abstract: A terminal receives configuration information from a first access network device. The configuration information includes a paging area information that indicates a paging area for the terminal in a first mode. In the first mode, the terminal sends a first message to a second access network device when the terminal is in a cell that does not belong to the paging area. The first message includes a paging area update indication. The terminal then receives a connection establishment indication from the second access network device, and establishes a connection between the terminal and the second access network device. The terminal sends a second message to a core network device using the established connection between the terminal and the second access network device, the core network device releases a connection between the first access network device and the core network device established for the terminal in response to the second message.
