Abstract: In a device including a processor and a memory in communication with the processor, the memory includes executable instructions that, when executed by the processor, cause the processor to control the device to perform functions of connecting a remote device to a network via a first channel associated with a first tier level; determining that a tier level switch condition is met; sending, to a controller of the network, a request for tier level switch from the first tier level to a second tier level; receiving, from the controller of the network, an authorization for switching from the first tier level to the second tier level; and connecting the remote device to the network via a second channel associated with the second tier level.

Abstract: In a device including a processor and a memory in communication with the processor, the memory includes executable instructions that, when executed by the processor, cause the processor to control the device to perform functions of receiving, from a first network assigned to a first tier level, a request for tier level switch from the first tier level to a second tier level; determining that a second network assigned to the second tier level is capable of switching from the second tier level to another tier level; assigning, to the second network, a channel of the first tier level; and assigning, to the first network, a channel of the second tier level.

Abstract: An apparatus controlling channel assignments for a shared access system is disclosed. The apparatus generates a first registration in a database that indicates that a first channel is assigned to a device and sends the identity of the first channel to the device. The device may use the first channel to communicate with other devices in the system. The apparatus may receive a query from the device indicating the first channel is encumbered. In response to the query, the apparatus may send the identity of a second channel to the device, generate a second registration in the database that indicates that the second channel is assigned to the device, and generate an amendment to the database indicating that the first channel is encumbered. The apparatus may then verify whether the first channel is encumbered and remove or keep the amendment in the database based on the verification.

Abstract: Tier switching of spectrum access priority tier levels for networks in a multi-tier level spectrum access system is disclosed. The tier switching may be based on conditions in the networks to allow more efficient network/system operation. In an implementation, the switching of tier levels may be a swap of tier levels between a network/device and another network/device. In this case, the tier level of a network/device is switched or swapped with the tier level of another network/device and each network device operates at the tier level of the other network/device. In another implementation, the switching of tier levels may be a switching of tier levels used by a single network or a single device without any swap occurring with another network or device. In this case, the tier level of a network or device may be switched to another tier level for operation in the SAS.

Abstract: Injection molding apparatus has upper and lower mold halves that split along the center line of the parison cavity and the gate opening leading thereto. Each hot melt injection nozzle is received within a tubular insert cup having a reduced diameter tip that is seated within the gate opening. The cup is mounted to the lower mold half so as to remain secured thereto as the upper mold half opens and closes the mold. The base end of each nozzle has a swivel ball and socket relationship with the manifold block which supplies it with hot melt, while the tip end of each injection nozzle has a swivel ball and socket type interface with the interior front end of the insert cup, thus providing for dimensional variations in the parts of the tooling that arise during non-uniform thermal expansion and contraction thereof.

Abstract: The tip of the blow core on a stretch blow molding machine is slightly smaller in diameter than the neck of the preform into which it is inserted such that during both insertion and withdrawal there is no physical contact between the core and the preform. However, when the core tip is in place within the preform and the blow surge commences, a resilient sealing ring around the core tip expands into radial contacting engagement with the preform to seal off what would otherwise be an air escape route. When the air surge terminates, the ring contracts into a dove tail gland around the core tip so as to be substantially flush with the surface of the tip, permitting the core to be withdrawn without contacting the preform.
