Abstract: In a method of locating medical equipment to be serviced, a map of a medical facility is accessed using an electronic processing device. The map includes a plurality of medical equipment each having a tag indicative of a location thereof. A user input is received which is indicative of a selection of a medical equipment of the plurality of medical equipment. A list of service actions to be performed for the selected medical equipment is displayed on a display device of the electronic processing device.

Abstract: A service actions database stores credentials for performing respective service actions. A service engineer (SE) database stores credentials of respective SE's. In a method of authorizing a servicing session of a medical device, a service ticket to perform a servicing session of the medical device is received. Credentials of a candidate SE are retrieved from the SE database. One or more service actions are determined for resolving the service ticket. Credentials required to perform the servicing session are retrieved from the service actions database based on the determined one or more service actions. It is determined whether the credentials of the candidate SE satisfy the credentials required to perform the servicing session. An indication is output that the candidate SE is unqualified to perform the servicing session when the credentials of the candidate SE do not satisfy the credentials required to perform the servicing session.

The method includes: receiving Wi-Fi roaming data for wireless devices (12) connected to a wireless electronic data communication network (14) comprising a plurality of access points (APs) (16) dispersed through a facility; from the received Wi-Fi roaming data, determining single-AP disconnect events for the APs wherein a single-AP disconnect event for an AP comprises a disconnection of the AP from a wireless device followed by a reconnection of the AP with the wireless device without the wireless device connecting to any other AP during a time interval between the disconnection and the reconnection; and generating an alert (30) for any AP whose rate of single-AP disconnect events exceeds a predetermined single-AP disconnect rate alert threshold.

Abstract: At a service device (102), a user interface (106) is provided via which a user submits an order request (117) to order a requested part (X) via the at least one user input device (103). Co-replacement information (116) for the requested part (X) is identified using a co-replacements database (114), and is displayed on the display. For example, a second part (Y) commonly co-replaced with requested part (X) may be identified and recommended for replacement with part (X); or, if two parts (X) and (Y) are ordered then the co-replacement information may be to recommend ordering only one of these parts. At a server hosting the database (114), the order request is received from a service device and the co-replacement information (116) for the requested part is generated using the co-replacements database (114), and the co-replacement information is sent to the service device.

Abstract: Analysis of a log pattern for use in diagnosing a medical imaging device operates on log data including log events and service calls, each associated with a subset of log events within a service call time frame of a call time of the service call. Preprocessing (64) generates normalized log events (66) by removing or replacing content of the log events and linking each normalized log event with one or more service calls. Pre-analysis (68) identifies a test set of normalized log events that match a log pattern (40) and a test set of service calls (42) linked with the test set of normalized log events. The test set of service calls is analyzed (74) to identify hit service calls (46) each belonging to the test set of service calls and for which the log pattern under analysis has a hit.

Abstract: A wireless network comprises access points (APs) implementing roaming by way of handover of wireless devices between APs. Handover events over an analysis time interval are extracted from a wireless network log of the wireless network. Each handover event comprises a source AP from which a wireless device disconnects and a destination AP to which the wireless device connects. At least one handover frequency (HF) network topology graph is constructed fro the analysis time interval from the extracted handover events. The graph has nodes representing at least a subset of the APs of the extracted handover events and edges connecting pairs of nodes with each edge having a weight representing a count or frequency of handover events between the APs represented by the pair of nodes connected by the edge. A network diagnostic or visualization task is performed using the HF network topology graph.

Abstract: In an electronic data processing method, a first column and a second column of at least one table are identified which have a one-to-one or one-to-many relationship with fewer than a threshold number of violations of the one-to-one or one-to-many relationship. On a display, possible data errors in the at least one table corresponding to the violations of the one-to-one or one-to-many relationship are indicated. The identifying of the violations may include generating a weighted bipartite graph representing the first and second columns, and detecting the violations using the bipartite graph. The method may further include displaying, on the display, a user interface whereby a user accepts or rejects each indicated violation of the one-to-one or one-to-many relationship.
