  • Patent number: 10929275
    Abstract: A virtual private cloud (VPC) that includes one or more computing devices (e.g., a physical computing device, a virtual computing device, etc.) that each implement a service present in an actual production environment is provided herein. For example, at the request of a user, an instance deployment manager may replicate one or more of the services provided by an actual production environment such that the services can be executed by the computing devices within the VPC. The computing devices within the VPC may be configured to communicate with each other. However, the computing devices may not communicate with devices outside the VPC. Thus, the VPC may represent a sandboxed or isolated test stack that allows a user to independently test code within a replicated production environment.

  • Patent number: 9989591
    Abstract: Method and apparatus for performing Pattern-Controlled tests on an automatic test equipment (ATE). The ATE includes a diagnostic instrument and a control device. An application programming interface (API) is installed in the control device and operates to interact with a test program and thereby automatically controls the diagnostic instrument to perform a test. The test program is coded in a high-level programming language and defines a plurality of operation events for the test based on user input. The API identifies the operational events and determines respective operational types associated therewith. Events of an operational type are assigned to a respective pattern label. The pattern labels are then aggregated into a pattern burst which is downloaded to the diagnostic instrument.

  • Publication number: 20170004530
    Abstract: Providing offers based on a search query comprises receiving and storing offers from merchants. The system identifies a potential merchant name from search query terms and identifies offers from a database that are not associated with the potential merchant name. The system compares the potential merchant name to the identified offers and determines if the potential merchant name appears in a number of the identified offers that is below a threshold. If so, the system determines that the query term identified as a potential merchant system is likely to be an actual merchant name. In this case, the offer distribution system may select only offers from the actual merchant to present to the user.

  • Publication number: 20160239723
    Abstract: A solution is provided to enhance home security monitoring by pre-processing and post-processing home security surveillance data and by using a trained security model. A security controller receives motion data from motion sensors and digital cameras strategically installed in a home and pre-processes the motion data to detect possible candidates for the detected motion. The security controller is connected with a variety security sensors installed for monitoring home environment. Each of the security sensors sends an event signal to the security controller in response to a state change of the security sensor. The security controller analyzes the state changes and generates security alerts responsive to detection of security violation. A security server connected to the security controller post-analyzes the security surveillance video data to identify humans and animals responsible for the detected motion and trains a security model to guide the real time security monitoring by the security controller.
