Triggering of reference signals and control signaling
When triggering a user equipment (UE) to send a reference signal (SRS) the network configures the UE with multiple parameter sets, each having a timing indication. The UE's resource allocation grants multiple uplink (UL) subframes and identifies/selects one of those parameter sets. The timing indication of the selected set identifies one of the granted UL subframes, in one embodiment by counting only among the allocated/granted shortened UL subframes. This triggers the UE to send SRS in that identified shortened UL subframe. In one embodiment if no UL subframes in the grant are shortened this triggers the UE to send SRS in a subframe previous to an the allocated/granted multiple UL subframes. The same mechanism can be used to trigger feedback reports such as aperiodic channel state information or block ACK/NACK reports, where the different UL signaling being triggered is requested in the network's resource allocation to the UE. |

If there is insufficient cash on hand, the dealer is notified and is provided an opportunity to replenish the account so that the transaction may proceed. If there are adequate funds in the dealer account, the bank automatically transfers the amount of the purchase transaction in the SP S account, less the dealer's fee for the purchase. After funds are transferred from the dealer account, the PMC is notified of the transfer, at which time the PMC generates codes and issues the codes to the dealer. The dealer transfers the codes to the user and the user enters the codes into the unit. On a regular basis the bank electronically transfers funds from the SPS account into accounts held by parties entitled to receive the funds. |

Efficient resource status reporting apparatuses
Described techniques enable the tracking and reporting of resource utilization at multiple levels of granularity, the highest of which involves tracking resource usage by a particular object in aggregate. When aggregate usage for the particular object is within certain parameters, actual resource usage is not reported at the lower level of granularity, but is replaced by placeholder values. When aggregate usage for the particular object exceeds a threshold, the particular object is considered to be a “hot spot.” Resource usage for the particular object can then be reported (and tracked, if not already) at the lower level of granularity until the particular object is no longer a “hot spot.” The efficiency of the tracking may be further enhanced by leveraging a bifurcated counting mechanism in which a full count is updated only at selected sample times, with intermediate counters used to store changes in between sample times. |

Microwave frequency synthesizers with rapid frequency switching
It was found that certain VCO devices used in microwave frequency synthesizers exhibit prolonged ringing oscillation during extreme voltage jumps above a critical limit, but that this effect could be significantly reduced by splitting the voltage adjustment over multiple steps. This finding was used to improve the switching speed of such devices (e.g. wideband VCO with a computer processor, base frequency generator VCO and a frequency divider). Here, before implementing a command to switch frequencies (by changing the base frequency oscillator and frequency divider settings), the processor first determines if this change will require an extreme voltage jump likely to cause such oscillations. If so, the processor implements this voltage jump as a multiple step process, resulting in a significant reduction in the maximum time required to switch frequencies. |

Isolated DC-DC voltage converters
A switching voltage converter using an isolated topology includes a transformer for coupling power from an input source to an output load. The transformer must be protected to prevent saturation of its core due to excessive magnetic flux density as the transformer transfers power from its primary side to its secondary side.
