Abstract: Parts in a manufacturing or service facility are electronically tracked using wireless beacons and location tags, strategically positioned receiver devices in the facility, and a monitoring server. The wireless beacons and location tags are individually coupled to parts in the facility to be tracked and store beacon-, tag-, and part-specific identifiers that can be wirelessly communicated to the monitoring server through receiver devices or mobile devices of workers in the facility. In particular, the location tags transmit various identifiers when the mobile devices or wireless beacons are brought into close proximity to the location tags. The mobile devices allow workers to request on-demand and up-to-date work orders for the parts with location tags, and the wireless beacons communicate the location tags' identifiers to the monitoring server. The monitoring server uses the identifiers to track the locations of the parts and manage electronic work orders for the parts.

Abstract: Described are techniques for enabling a computing device, such as a slave device using a Bluetooth Advanced Audio Distribution Protocol (A2DP), to determine times when a master device is likely to be idle, during which communications using an alternate protocol, such as Wi-Fi may be exchanged. The length of a delay period may be determined based in part on counts of successive communications received from a master device. The length of a transmission period for use of the alternate protocol may be determined based in part on lengths of time between sets of communications received from a master device. If no communication is received from the master device for a length of time greater than or equal to the delay period, data may be communicated using the alternate protocol for a length of time less than or equal to the transmission period.

Abstract: Various combinations of these teachings solve dual errors for a user equipment UE checking whether a private cell is allowed when handing over between serving and target cells, where the PLMN and/or list of EPLMNs of the serving and target cells may differ.
