Abstract: The invention describes a pedalboard for holding instrument effect pedals (guitar, bass, etc) which stores two layers of instrument effect pedals upon vertically stacked platforms for more compact storage but which can also be opened/expanded using a four-bar linkage mechanism to allow for access to the lower effect pedals during musical performance or practice. The upper platform may be disconnected from the front links and can pivot upward to allow for further access to the lower platform.

Abstract: Systems and methods are described for donor access node (DeNB) selection at a relay access node (AN). A plurality of DeNBs may be identified, the DeNBs being located within a radio range of the relay AN. A metric may be calculated at the relay AN and used by the relay AN to select multiple, preferred DeNBs from the plurality of DeNBs. The relay AN may simultaneously request a connection to each of the multiple, preferred DeNBs. Data signals may be combined for transport at the relay AN and sent to end-user wireless devices, the multiple, preferred DeNBs, or both.

Abstract: A method, system, and medium are provided for increasing carrier-to-interference-and-noise ratio (CINR) gain in a long-term-evolution network deploying beam forming (BF) technologies. Adjacent eNodeBs, each serving a respective user equipment (UE) located at the boundary between the two eNodeBs, communicate BF parameters to each other. Each eNodeB uses the received BF parameters to adjust its DL transmission beam in order to decrease the interference at each of the respective UEs. By adjusting the DL transmission beam to decrease interference, CINR gain at the UEs is correspondingly increased.

Abstract: Insulating ribs are formed into one or more portions of a housing that encloses circuitry of an electrical device. Components mounted on a board are separated according to whether they are related to a primary side of a power transformer or a secondary side. Primary related components are typically mounted on the primary side of an isolation slot formed into a circuit board and components related to the secondary are mounted on the other side. The insulating ribs are strategically placed to protrude through the slots when circuit board is mounted to the housing portion. Thus, when the housing portion is joined to another housing portion, which also may include insulating ribs strategically placed, the ribs increase the breakdown voltage of the boundary.
