Selective micro-transmission in downlink control information (DCI) message
When a base station has just a small amount of data to transmit to a served UE, the base station will transmit the data to the UE in a DCI message on a PDCCH, rather than using the DCI message to allocate PDSCH resources to carry the data and transmitting the data on the allocated PDSCH resources. Further, the base station could advantageously make use of a standard DCI message format but could transmit the data in DCI message fields that would otherwise be used to allocate PDSCH resources or otherwise to facilitate PDSCH transmission, since those DCI message fields would not be needed when the data is transmitted in the DCI message itself. |

A base station maps an enhanced physical downlink control channel (E-PDCCH) sequentially to resource elements for transmitting the E-PDCCH in each orthogonal frequency division multiplexing (OFDM) symbol according to an order of OFDM symbols used by the E-PDCCH of a user equipment (UE).

Video quality adaptation with frame rate conversion
During video coding, frame rate conversion (FRC) capabilities of a decoder may be estimated. Based on the estimated FRC capabilities, an encoder may select a frame rate for a video coding session and may alter a frame rate of source video to match the selected frame rate. Thereafter, the resultant video may be coded and output to a channel. By incorporating knowledge of a decoder's FRC capabilities as source video is being coded, an encoder may reduce the frame rate of source video opportunistically. Bandwidth that is conserved by avoiding coding of video data in excess of the selected frame rate may be directed to coding of the remaining video at a higher bitrate, which can lead to increased quality of the coding session as a whole. |

The present disclosure eliminates the unwanted conduction of the body diode of the low side switch or the unwanted conduction of the low side switch in coupled phases of DC-DC converters operating in DCM to increase efficiency. Specifically, in one implementation, by detecting strong or weak coupling, the present disclosure eliminates body diode conduction in strong coupling by turning on the low side switch and eliminates negative body diode current in weak coupling by turning off the low side switch. Further, for multiphase switching DC-DC converters with coupled inductors operating at light load (i.e., in DCM), when a high side switch of a first phase is turned on, the body diode of a low side switch of a second phase is adaptively bypassed if needed, blocked by specific design, or prevented from conducting by reducing forward voltage across the body diode. |

A switched mode power supply is provided comprising a pulse-width-modulator (PWM), a power section, and a drive section for the power switch. The drive section consists of a new method of driving the power switch where it is desired that the switch terminals be isolated from the PWM ground.

One problem that arises with switch drivers that utilize isolation transformers during an overload event or even an ordinary shutdown event is that the driver does not turn off and hold off the power switch when it is commanded to do so. This invention solves these problems by insuring that the appropriate components are de-energized in the classical dc-restore circuit which will prevent the PWM from losing control of the power switch. |

Reduced-vibration stepper motor
A stepper motor has a stator winding assembly with a permanent ring magnet located radially outside of electromagnetic windings for the stator poles. The permanent ring magnet remotely magnetizes a rotor seated by bearings on an axial shaft so as to rotate within the stator winding assembly, thereby freeing up space within the rotor for an internal damper. The rotor has a cylindrical damping weight enclosed within, but not fixed to, the rotor. The weight ideally has a rotational moment of inertia that substantially matches that of the rotor. The weight is elastically coupled to the rotor by a viscous material contained in the rotor and filling the space between the weight and the rotor and between the weight and the axial shaft. The viscosity of this material is selected such that motion of the weight is delayed, preferably so as to be substantially 180° out-of-phase with, but at the same frequency as, the stepping rotation of the rotor. The weight thereby serves as a counterweight to the rotor so as to cancel vibrations generated by stepping of the rotor. |
