  • Publication number: 20240134463
    Abstract: Methods and systems for touchless control of a device include receiving at least one image; determining a first map, the first map including a function that generates a correspondence between data associated with the image to a feature space; determining a second map including a representation of a user in the image based on the first map; determining a third map comprising a field associated with the data in the image; determining a characteristic of the user based on one or more of the second map and the third map; and tracking the characteristic of the user to generate a historical data of the characteristic for performing the touchless control of the device.

  • Patent number: 9325435
    Abstract: A system and method for facilitating comparison of radio frequency (RF) data signals transmitted by a device under test (DUT) and received by a test system. A RF data signal received from a DUT is analyzed to provide analysis data indicative of conformance of the DUT operation with one or more applicable signal standards. The RF data signal is also converted to related conversion data that can be stored with state machine data corresponding to states of the signal testing subsystem. This state machine data can then be processed as needed with the analysis data and conversion data for off-line tasks such as debugging new test programs and procedures.

  • Patent number: 8842552
    Abstract: Method and system for facilitating testing of multiple time-division-duplex (TDD) data packet signal transceivers. Replicas of a data packet signal are transmitted by a tester to multiple TDD devices under test (DUTs), where the replicated signal is either a null or TDD data packet signal. In one embodiment, replica null data packet signals are transmitted for a predetermined time interval sufficient for the DUTs to synchronize with the tester. In another embodiment, following successful and unsuccessful receptions of responsive signals from respective DUTs indicating successful reception of their respective replica TDD data packet signals and, therefore, synchronization with the tester, corresponding replica TDD data packet signals are provided with data packet signal characteristics causing such replica data packet signals to fail to conform or to conform, respectively, with a predetermined data packet signal standard.

  • Patent number: 6823458
    Abstract: An apparatus and method for securing system resources in a concurrent multiple operating system environment wherein when a client device or application requests access to system resources the request is received by the apparatus which then determines if the resources requested are currently being used by another client or application. Based on a unique identifier sent by the client or application, the apparatus searches a resource state data structure for the resource requested and compares the unique identifier sent by the client or application with the unique identifier stored in the resource state data structure in association with the requested resource. If the two unique identifiers are the same, the client/application is provided with access to the requested resource. If the unique identifiers are different, the client/application is denied access to the requested resources.
