Abstract: A compression die configured to crimp a composite core is disclosed. The compression die includes an outer body having a tool engaging surface, and an inner body coupled to the outer body. The inner body has a crimping area, wherein the crimping area of the inner body includes ten planar surfaces. The ten planar surfaces are positioned at an angle with respect to an adjacent planar surface such that the combination of the ten planar surfaces form a decagon shaped channel. Crimping is performed by the compression die by inserting the composite core into an encasing connector, which is then inserted into the decagon shaped channel of the compression die. A radial force towards the center of the decagon shaped channel is applied until an outer circumference of the encasing connector containing the composite core fully engages a surface area of each of the ten planar surfaces.

Abstract: Polymer systems comprising poly(vinyl chloride), a non-petroleum based filler, and a polyester additive, wherein the polymer system is highly filled, and articles made therefrom, are described. The high loading of filler (e.g., talc, calcium carbonate or a combination thereof) is achieved by incorporation of polyester additives such as polyhydroxyalkanoates. High filler loading without significant reduction of relevant material properties can be associated with cost savings and environmental benefits.

Abstract: A base station node (BS) of a heterogeneous radio access network comprises a terminal locator (34) and a scheduler (36). The terminal locator (34) obtains an indication of location of a wireless terminal (30) in a cell served by the base station (BS), e.g., whether the wireless terminal (30) is in a center region (M) or an edge region (E) for the cell served by the base station node (BS). The scheduler (36) uses the indication of location to assign to the wireless terminal (30) a frequency of a frequency bandwidth usable by the heterogeneous radio access network. The scheduler (36) assigns a frequency from a partitioned portion of the frequency bandwidth if the cell served by the base station node is a micro cell and the wireless terminal is in an edge region of a micro cell. The scheduler (36) also assigns a frequency of the frequency bandwidth if the cell served by the base station node is a micro cell and the wireless terminal is in a center portion of the micro cell.

Abstract: A method of interference management of multiuser in-coverage device-to-device communications at a network node is presented. A WAN signal from a WAN device is received, the WAN signal being mixed with an interferer signal caused by a D2D communication between a transmitting D2D device and a receiving D2D device of a D2D pair. An attribute value difference between a first attribute value of the WAN signal and a second attribute value of the interferer signal is determined. If the attribute value difference does not meet a target difference, a transmission parameter of at least one of the WAN device and the transmitting D2D wireless device is controlled to adjust the difference to meet the target difference.
