Retention insert and connection device for dental applications
A retention insert (1), for connecting a dental prosthesis structure to a dental implant or capping structure having a head designed for a press-fit connection, comprises a substantially circular disc-shaped end face (12), and a substantially ring-shaped retention edge (11), which protrudes from the end face (12) and has an outer surface (114). The end face (12) has an opening (121), and, starting from an end (11b) of the retention edge (11) directed away from the end face (12), a substantially axial slit (14) extends through the retention edge (11) and the end face (12) to the opening (121) of the end face (12). Connected to the opening on the end face, the slit of the retention insert according to the invention is a relatively simple structure which ensures that the retention insert, and in particular the retention edge thereof, has an elasticity sufficient for snap-fitting it onto the head or the patrix head. At the same time, a spring force from the snapped-on retention edge can therefore act on the head, such that the retention insert and parts connected thereto are clamped on the head. Moreover, this retention edge and this opening also have the result that imprecisions in the position of the implant structure, and in particular lack of parallelism, and also the effects of forces from different directions can be compensated, without the retention insert or parts thereof being substantially squeezed or similarly deformed. |

Motion picture high dynamic range imaging
A process is provided for providing high contrast motion picture imagery. The camera system includes a physical architecture that enables multiple sensors to simultaneously acquire a visual scene without parallax or dissimilar exposures. The system architecture enables current off the shelf components to be used to develop the architecture or a specific sensor array to be developed. The architecture includes optical components that split an incident light ray into multiple beams of varying intensity. Each respective split light ray is then attenuated further with neutral density filters for the wavelengths to be observed before the light ray impacts the respective pixel sights. A process has been developed to use the camera system architecture to stochastically recombine the acquired energy and estimate what the original energy was before attenuation. The process involves the development of an optimal non recursive weighting function that can be used and constructed into a lookup table. The weighting function is used to minimize the error associated with symmetrically distributed error sources. A second filtering routine then takes place to remove the nonsymmetrical sources of error such as intraocular flare. This is accomplished by estimating the symmetric errors prior to acquisition and detecting when a sensors radiant exitance estimate does not fall within this symmetrical error bounds. The final reconstructed HDR image is formed once a pool of cameras is determined and a weighting average of the viable guesses is used to estimate the actual scene radiant exitance, or in a non-unitary sense, a photometric radiance. The HDR image can be saved as a high bit depth image or tone-mapped either by the method introduced or by other means and stored to memory via convention 8-bit encoding methods for storage. |

Optimised broadband line testing
This invention relates to a method of managing a digital subscriber line, where an optimum point at which to trigger a line test on the DSL line is determined. The invention continuously measures the signal to noise (SNR) margin on the DSL line, and compares the measurements to predetermined conditions based on SNR margin characteristics associated with a population of good lines. Once the SNR margin measurements fail to meet the predetermined conditions, an electrical line test is triggered. Thus, monitoring is done in the DSL domain, but the line test triggered is in the electrical domain. In an improved method, moisture level sensors provide a measure of the atmospheric moisture levels experienced by the line. If the SNR margin measurements fail to meet the predetermined conditions, and in addition there is a correlation with atmospheric moisture levels, then a line test is triggered on the line. This improvement picks up faults associated with wet joints that are generally intermittent in nature, and otherwise difficult to identify and properly test. |

The method includes: (a) a step of setting a stability reference value and a corresponding sampling interval; (b) a step of inputting measurement data; (c) a step of calculating a first moving average using the measurement data input in the step (b) by applying a basic sampling interval; and (d) a step of calculating a second moving average for the measurement data by applying the sampling interval corresponding to the stability reference value set in the step (a) if the first moving average is equal to or larger than the stability reference value. |

Feed-forward bias circuit
A feed-forward bias circuit biases body bias terminals of transistors of another circuit to compensate for PVT variations in the other circuit. In some aspects, the feed-forward bias circuit compensates for transistor process corners in a circuit by enabling the generation of different bias signals under different corner conditions. In some implementations, the feed-forward bias circuit is used to bias a delay circuit so that the delay circuit exhibits relatively constant delay characteristics over different PVT conditions. |

Radio-frequency front-end circuit and communication device
A radio-frequency front-end circuit includes a first filter that has a first pass band and is connected to an antenna common terminal, a second filter that has a second pass band and is connected to the antenna common terminal, a switch that includes a common terminal and selection terminals, the common terminal being connected to the first filter, and a third filter that is connected to one of the selection terminals and is disposed between the switch and an input/output terminal. A reflection coefficient of the first filter alone in the second pass band viewed from the antenna common terminal is larger than a reflection coefficient of the third filter alone in the second pass band viewed from the antenna common terminal. |

Sun tracking solar power system hardware and method of assembly
A solar energy collection system can include improved mounting hardware for reducing hardware costs and labor required for assembly. For example, mounting hardware can include surfaces for supporting part or all of the weight of a solar module as it is brought into contact with mounting hardware and then moved into a final engaged position. In some systems, a torque tube can include saddle mount assemblies that allow a solar module to be partially engaged and a registered with the saddle mount while being pivoted into a final locked engagement. Some systems can include arrangements sufficient to support the full weight of a solar module in a disengaged position, and as it is moved into a final engaged position. Some systems can include a configuration of apertures and interference or snap-fit features for providing tool-less connections, thereby simplifying the assembly process. |
