Abstract: A multi-band user equipment (UE) is configured to operate in a single frequency band mode or a multiple frequency band mode. When operating in a single frequency band mode, the UE activates a bypass switch to route uplink signals of a first band around a multiplexer and reduce the insertion loss for the band.

Abstract: Techniques provide rendezvous point link (RPL) resiliency for bidirectional protocol independent multicast (PIM-BIDIR) in a computer network. According to the techniques, when two or more RPL partitions have a same RPL subnet, routers on the RPL subnet are configured to elect an active RPL partition that will function as a RPL. The routers on any inactive RPL partitions may then treat the inactive RPL partitions as regular links in the RPL subnet and build a route to the active RPL partition. In some examples, the network is configured to include the two or more RPL partitions with the same RPL subnet as Anycast RPLs in the network. In other examples, the routers on the RPL subnet are configured to detect when an original RPL is separated into the two or more RPL partitions due to a failure of the original RPL.

Abstract: A guide rod, which has a diameter expandable tip end portion and restricts the oscillation of a connecting rod and a piston, is inserted into a cylinder bore via an opening adjacent to a crank chamber of the cylinder bore, and the piston is inserted into the cylinder bore via a cylinder head mounting side opening with the connecting rod positioned at a leading end. The diameter of the tip end portion of the guide rod is increased in a hole of a semi-circular arc-shaped end portion positioned at tip end of the connecting rod in the insertion direction, and thus the connecting rod is engaged with the guide rod. The guide rod moves and the connecting rod is pulled into the cylinder bore until the semi-circular arc-shaped end portion of the connecting rod sits on a crankpin of a crankshaft.

Abstract: Systems, methods, and apparatuses are disclosed to facilitate wireless communications. User equipment (UE), such as a mobile device, identifies data congestion and transmits a recommended data rate modification wireless signal (e.g., a recommended reduced data rate) to the base station that is transmitting data to the UE. The base station may reduce the data rate of the down link (DL) to the reduced data rate. The UE may then receive data from the base station at the reduced data rate. Therefore, flow control may be implemented at the base station side (e.g., sometimes referred to as the Network (NW) side) based upon the reduced data rate modification determined and transmitted by the UE to the base station. In this way, the data rate transmission to the UE can be reduced to allow the UE to successfully process received data and successfully perform its functions.

Before the fixing, the position of the actuating device which corresponds to the closed position is set by application of the corresponding voltage to the electric actuating device. Subsequently, a prestressing force is applied to the coupling element coaxially with respect to the actuating rod via a pneumatic actuator.
