Abstract: Systems and methods for allowing an Internet of Things device to circuit switch among embedded subscriber identity modules (eSIMs) are provided. A communication circuit for operating a plurality of eSIMs may include a first and second eSIM. The communication circuit may further include an eSIM card interface bus configured to provide signals to and from the eSIMs, the bus including a data line adapted to receive a data signal. The communication circuit may further include an eSIM select line configured to receive an eSIM select control signal to select between the eSIMs to communicate with a wireless network. The communication circuit may further include a selector connected to the eSIM select line, the selector adapted to switch the data signal between the first and second channel to provide the data signal to the first and second eSIMs based at least in part on the eSIM select control signal.

Abstract: Embodiments of the disclosure can relate to a ceiling mounted air distribution system for a railcar. According to one embodiment of the disclosure, a ceiling-mounted air distribution plenum may include: a diffuser configured to transmit air to at least one first air channel, the at least one first air channel having a first end configured to couple to the diffuser, a second end distal from the first end; at least one second air channel disposed proximate to and longitudinally with the at least one first air channel, the at least one second air channel having a first end configured to couple to the diffuser, a second end distal from the first end, and at least one air distribution hole, and at least one channel divider disposed to separate the at least one first air channel and the at least one second air channel.

Abstract: A data structure and computer-program product for providing tool design and instructions in a dynamic manufacturing environment are provided. The data structure includes a plurality of objects for abstracting tool resources. Each object represents all changes that relate to one of a tool or a part of a tool. The instances of the objects are based on product information and are generated for associated instructions for tool usage in the manufacturing environment. The product information includes information identifying configuration of the product and a definition of a functional deliverable of the product. The information identifying configuration of the product includes product option information. The functional deliverable of the product includes production line number where the object applies.
