In specific cases, a constant voltage power supply is used to power an LED lighting apparatus in which there are uncertainties within the forward voltages of the LEDs, which in turn creates uncertainty with respect to the current level flowing through the LEDs. To manage these uncertainties, the current flowing through the LEDs is measured by determining a voltage level across a known resistor and calculating the current level. To prevent the known resistor from causing a significant reduction in the efficiency of the overall light engine, the circuit includes one or more transistors in parallel with the known resistor to reduce the effective resistance in the LED circuit during times that the current is not being sensed. |

ENB, UE and method for physical resource block allocation in MTC UE
Embodiments allow an eNBs and a target UE to both calculate which resource block groups (RBGs) to use to transmit data. Because the RBGs that will contain information of interest can be pre-calculated, there is no need to receive and store all RBGs in the transmitted signal before decoding the signal and identifying which RBGs are of interest to the recipient. This allows receivers to buffer and/or store only those RBGs that will contain received information and discard others. The amount of information that needs to be stored and/or buffered thus is less and can result in receivers with less memory and, hence, lower cost. In order to calculate which RBGs are to be used to transmit and/or receive information, a logical RBG index is first calculated and the logical RBG index is mapped to a physical RBG index. |

The current document is directed to virtualized PMUs provided by virtualization layers. The currently disclosed virtualized PMUs are decoupled from the underlying PMU hardware features of processors on which the virtualization layer executes.

Distributed connection management
Persistent connections between multiple client devices and multiple back-end service components are managed using a consistent hashing-based approach to route distribution. A load balancer distributes the connections across multiple gateway servers. Each connection is associated with a device having an identifier, which can be hashed using a selected hashing algorithm. The gateway servers are assigned values over a hashing range. When a connection is established for a device, the hash value for that device can be mapped to a corresponding gateway server. The primary gateway server establishing the connection can store information (e.g., the port or interface) for the connection, and can send identifying information to the corresponding gateway server determined by the hash value. When a backend service wants to locate the connection, the service hashes the device identifier to determine the corresponding gateway server, which returns the identity of the primary gateway server hosting the connection. |

Mechanisms for certificate revocation status verification on constrained devices
A process is provided for communication security certificate revocation status verification by using the client device as a proxy in online status verification protocol. The process utilizes a nonce of an authentication protocol request message (nonce_A) to derive the nonce for the revocation status protocol request (nonce_S) to reduce the number of message exchanges needed between the client and the verifier devices, and a mechanism to send the nonce (nonce_S) prior to actual authentication protocol execution to ease the connectivity requirement of client device from on-demand connectivity to periodic connectivity. Similar functionality is achieved using a random seed established between the verifier and client. The verifier picks a seed for random number generation and sends that seed to the client. The client derives the nonce_S from the seed before status protocol execution, and the verifier derives the nonce_S from the seed before proxied status response verification. |

Tunable matching network with phase-switched elements
Described is a phase-switched tunable impedance matching network (PS-TMN). The PS-TMN has an input that can be coupled to a source and an output that can be coupled to a load. The PS-TMN includes one or more phase-switched reactive elements and a controller. The controller provides a control signal to each of the one or more phase-switched reactive elements. In response to one or more control signals provided thereto, each phase-switched reactive element provides a corresponding selected reactance value. |

System and method for detecting loss of input phase by sensing before power rectifier
A system for detecting a decrease in or loss of an input phase to a motor. A power rectifier rectifies and combines three input voltages to produce an output voltage to power the motor. A PFC circuit manages the power flowing to the motor. A sensing circuit located between the power rectifier and the PFC senses a voltage level of the power rectifier's output voltage. Alternatively, a sensing rectifier is connected before the power rectifier, and the sensing circuit senses the voltage level of the sensing rectifier's output voltage. A microprocessor compares the sensed voltage level to a threshold voltage level which is indicative of the decrease in or loss of one of the three input voltages, and if the former drops below the latter, then the microprocessor sends a signal to either shut off the motor or cause the PFC circuit to reduce the power flowing to the motor. |
