Abstract: In a network Performance Measurement (PM) model, network equipment (10) maintains (102) a ManagedElement object. The ManagedElement object contains one or more ManagedFunction objects which perform and report measurements. Each ManagedFunction object has one or more Measurement objects (106) that specifies a measurement, and lists a reporting period. The ManagedElement object contains a PMControl object (104), which specifies the reporting mode and includes an administrative state attribute of the ManagedElement object that is controlled by the network management system (20). The ManagedElement object controls (110) an operational state attribute of the PMControl object based on resources to perform the measurement and access to the relevant reporting mechanism (108). When both states of the PMControl object are set to a functional value (112), the ManagedFunction objects perform (114) and report (118) the results of measurement specified in associated Measurement objects.

Abstract: For ultrasound imaging using a matrix transducer, interconnects or switches are provided to allow sub-arrays forming a 1D array, such as with sub-arrays one element wide with the maximum number of elements in elevation. Where groups are used to limit the switches and available system channels per group, an extra switch may connect between elements of different groups through a group output to extend a sub-array across groups. To further limit the number of switches, the group may be sub-divided where different combinations of sub-groups are connectable with different combinations of the system channels for the group.
