A technique determines which configuration change(s) caused an application invocation failure of a computer application without the need for a knowledge database. To determine which configuration change is the most likely cause, the cause analysis program checks other computers that have experienced the same configuration changes. The cause analysis program checks and counts the application invocation results before and after each configuration change is done. If the same configuration changes are found in the other computers, the program checks whether each configuration change caused or cured the same problem in that computer. The program counts the similar cases for all of the computers. Subsequently, the program calculates the ratio of those instances involving a change from success to failure and the ratio of those instances involving a change from failure to success out of all instances for each configuration change.

Media hub devices with passive monitoring of user devices and targeted media transmission through in-channel transmission or shifted channel transmission

Номер: US20170046676A1
Автор: Angus BERRY, James B. Clack
Принадлежит: Catalina Marketing Corp

Systems and methods associated with media hub devices are provided that passively monitor user devices and transmit targeted media through in-channel transmissions that use the same channel used to monitor the user devices, or shifted channel transmissions that are different than the channel used to monitor the user devices. For example, a media hub device may passively monitor customer devices by scanning a wireless communication channel and obtaining device identification information transmitted by a user device that communicates the device identification information via the wireless communication channel. A media hub device may link the user device with a particular user or may anonymously monitor user behavior, through the monitored user device, without explicit knowledge of the identity of the user. Targeted media may be provided to the user device either in-channel using the same channel used to passively monitor the user device or a shifted channel using a different channel.
