Abstract: A powder bed additive manufacturing apparatus includes a build sleeve, a build platform for supporting a powder bed and object during a build, the build platform lowerable in the build sleeve, and at least one acoustic sensing system. The acoustic sensing system includes an acoustic emission sensor and an acoustic waveguide. The acoustic waveguide extends through the build platform such that a receiving end of the acoustic waveguide distal from the acoustic emission sensor abuts a surface of a build substrate removable mounted to the build platform to transmit structure-borne acoustic waves from the build substrate to the acoustic emission sensor.

Abstract: A battery powered wireless apparatus, method, and system. A battery powered wireless node operates to communicating with a gateway on a local area network through the network communication device, cease communication with the gateway after a predetermined period for a predetermined interval of time, and communicate with the gateway continuously when an event occurs.

Abstract: Various examples for performing remote authentication of a virtual subscriber identity module (SIM) on a multi-SIM, multi-standby communication device include receiving, on a first subscription of the multi-SIM, multi-standby communication device, an authentication request from a virtual SIM network. The multi-SIM, multi-standby communication device may respond to one or more acknowledgement requests sent from the virtual SIM network to the first subscription before tuning from the first subscription to a second subscription of the multi-SIM, multi-standby communication device to send the authentication request to a remote server. Upon receipt of the authentication response from the remote server through the second subscription, the multi-SIM, multi-standby communication device may send the authentication response to the virtual SIM network through the first subscription.

Abstract: Systems, methods, and devices for wireless communication by a wireless communication device are described. A circuit switched fallback from an LTE cell to a GERAN cell is initiated. A system information type 3 message is received. The GERAN cell is accessed based on the system information type 3 message without receiving a system information type 13 message. A circuit switched connection is established on the GERAN cell. Other aspects, embodiments, and features are also claimed and described.

Abstract: A linear guide assembly which includes a slide body that is moveably supported on a guide rail by a non-rolling bearing insert. A channel extends longitudinally through the body and the guide rail is received in the channel. The bearing insert facilitates longitudinal movement of the body along the rail. The nature of the mounting of the bearing insert to the body in the channel is such that the bearing insert can be readily removed from the body when excessively worn and replaced without also requiring replacement of the body.
