Abstract: A near field energized electronic valve actuator includes a power receiver that enables powering of control electronics using wireless RF energy received from an external device such as a laptop computer or smart cellular telephone handset when conventional power is unavailable to the actuator, thereby enabling exchange of data between the external device and the control electronics. Embodiments further enable data exchange between the control electronics and non-volatile memory during the wireless energization. The data can be exchanged, for example, during initial configuration of the actuator before customer delivery, during an unpowered maintenance period to retrieve operational log information stored by the control electronics, and/or to retrieve valve position information measured by a position sensor and/or fault-relevant data from the actuator when power has been interrupted due to an actuator or valve failure.

Abstract: A technical support incident resolution facility handles incidents, which are unexpected results which occur during the use of products. Within a vendor environment, a diagnostic knowledge trees database stores diagnostic knowledge trees for the products. A copy of a subset of the diagnostic knowledge trees is downloaded to a client environment. The subset of diagnostic knowledge trees provides diagnostic information for a subset of the products which are supported within the client environment. The copy of the subset of the diagnostic knowledge trees are used to supply diagnostic information to the client for incidents which potentially occur when a diagnostic program attempts to analyze the subset of the products.

Abstract: Linear accuracy of the output-signal frequency of a scanning oscillator is aintained through monitoring the location in a shift register of a pulse whose position is indicative of the frequency error from a desired scanning oscillator output-signal frequency.
