Abstract: A method for interference-free, centrally controlled switchover from a first to a second program channel in a data transmission system for distributing encoded program data streams to multiple subscribers includes delivering at least two program data streams, each of which is associated with a separate program channel, to a separate, controllable encoder. The program data streams are encoded in the associated encoders. The encoded first and second program data streams are fed into a distribution network. One encoded program data stream is delivered through a routing device to at least one target subscriber. Control parameters are provisioned in a central control device which permits a synchronized activation of the controllable encoders and at least one switching device for interference-free switchover of the program channels.

Abstract: Subscriber travel behavior is defined using cellular call location data. The defined travel behavior is used to segment the customer population. In a further aspect of the disclosed principles, a method to consolidate numerous of price plans is disclosed wherein price plans are grouped using cluster analysis. In the context of this disclosure, the term “cluster analysis” encompasses a number of different algorithms and methods for grouping objects of similar kind into respective categories to thus organize observed data into meaningful structures. In this context, cluster analysis is a data analysis process for sorting different objects into groups in a way that the degree of association between two objects is maximal if they belong to the same group and minimal otherwise.

Abstract: A hydraulically operated wedge lock system provides a releasable mechanical lock between telescoping boom segments. Each wedge lock mechanism includes a stationary backing wedge block that defines an angled smooth surface. A stationary shaft and piston is supported generally parallel to the backing wedge block. A slidable wedge block biased by a spring to a locked position is supported for reciprocal movement on the shaft along the angled smooth surface. Hydraulic fluid urges the slidable wedge block against the bias of the spring to an unlocked position.

Abstract: A multi-mode hybrid drive train offers selective operation in any one of series, parallel, and power split modes. The multi-mode hybrid drive train includes two planetary gear sets and a collection of specifically placed brakes and clutches relative to those gear sets. The first planetary gear train includes a power input for receiving power from a primary rotational power source, as well as a first sun gear, first carrier and first ring gear. The second planetary gear train similarly includes a power input as well as a second sun gear, a second carrier connected to a final drive, and a second ring gear. A first motor is linked to the first sun gear and a second motor is linked to the second sun gear such that selective activation of the clutches, brakes, and motors places the multi-mode hybrid drive train in a selected mode of operation.

The optical mirror element typically includes a first, reflective surface, and a second surface having uneven or granular features, wherein light passing through the first surface is diffusely reflected by the uneven or granular features of the second surface. The optical mirror elements are particularly well suited for use in Herriott Cell arrangements in gas analyzers.

Abstract: A method for concentrating a particulate matter, comprising at least two constituents of different densities, in which a slurry of particulate matter is subjected to centrifugation and to centripetal pulses in a centrifugation chamber. A dense fraction of the slurry and a light fraction of the slurry are drawn off separately from the centrifugation chamber. In order to produce the centripetal pulses, a fluid is injected into the slurry, in a direction oblique or tangential to the direction of centrifugation. The fluid is injected substantially continuously into the slurry.

Abstract: A method for controlling a real-time media stream between a sender and a receiver. The method includes streaming, from the sender, media packets over a network at a bit-rate, determining at the sender a loss-rate for the streamed media packets not received at the receiver. The sender optionally generates duplicate packets for a selected number of media packets and streams the duplicate packets over the network when the loss-rate is above a first loss-rate threshold, or varies the bit-rate of streaming the media packets over the network when the loss-rate is above a second loss-rate threshold.

Abstract: The present invention discloses a method for obtaining an attenuation factor. The method is adapted to process the synthesized signal in packet loss concealment, and includes: obtaining a change trend of a signal; obtaining an attenuation factor, according to the change trend of the signal.
