Methods and an apparatus for enhancement of source coding systems utilizing high frequency reconstruction (HFR) are introduced. The problem of insufficient noise contents is addressed in a reconstructed highband, by using Adaptive Noise-floor Addition. New methods are also introduced for enhanced performance by means of limiting unwanted noise, interpolation and smoothing of envelope adjustment amplification factors. The methods and apparatus used are applicable to both speech coding and natural audio coding systems.

In a case where a CPU provided in an information distribution center has received, from a navigation apparatus, vehicle information together with a request command for requesting traffic information such as current traffic information, the CPU sets a road category that serves as a distribution target of the traffic information, based on one of a distance and a required travel time from a vehicle position to a destination. The CPU then extracts the traffic information that corresponds to the set road category and distributes it to the navigation apparatus.

Sealing device for sealing at least one zone of underpressure or overpressure adjoining a moving surface that includes at least one sealing element, positionable opposite the moving surface to form a front and a rear, with respect to a surface running direction. The sealing device includes a sealing section located at the front and a ventilation section located at the rear. The sealing section is structured to sealingly interact with the moving surface; and the ventilation section is structured and arranged to form a gap with the moving surface that widens in the surface running direction.

A technique for managing power usage in a local communication network. The network includes at least one device having at least one operation phase. A processing unit receives information related to at least one operation phase of the device after detecting an operation phase change. The information includes power used by the device during the phase and an estimated duration of the phase. The processing unit determines projected power usage within the local network for the duration of the operation of the device, the projected power usage taking the form of at least one power usage increment and an associated increment duration. For a power usage increment, the processing unit: determines an output current to be output by at least one battery in order to at least partially compensate the increment; and sends, to the battery, a command to discharge the output current determined for the duration of the increment.

A method for controlled operation of a heated industrial furnace having a furnace chamber is provided. Fuel is conducted into the furnace chamber virtually without combustion air and a gaseous oxygen carrier is also conducted. The supply of fuel and the gaseous oxygen carrier is controlled by a control loop. A first adjustable manipulated variable in the form of a flow of fuel and / or a second adjustable manipulated variable in the form of a flow of the gaseous oxygen carrier is set by a final controlling element. In the control loop, an energy requirement is determined and fed to a quantitative control and to a quantitative fuel control for the fuel. The flow of the gaseous oxygen carrier is determined as a process value of a flow of the gaseous oxygen carrier and the flow of fuel is determined as a process value of a volumetric flow of fuel.

The invention discloses a complex plain river network generalization method achieving an approximately-uniform water storage relation. The method includes the steps that river channel geographic information data are obtained and processed; a simulated river network polygon is constructed; total water storage amount parameters of a generalized river network inside the simulated river network polygon are determined; the overlapping width of each simulated river sections of the river network polygon is determined; the width overlapping position of each river section of the river network polygon is determined. The water storage capacity of the generalized river network can be made to be approximately uniform with that of a prototype river network, simulation precision can be effectively improved, and the flood risk is easily analyzed; for the water administrative department in charge, defined data requirements are provided, and therefore data compiling is easily performed in management work of the plain river network; for scientific researchers in the water conservancy industry, the method is adopted for constructing a generalized river network hydrodynamic model, and in this way, it can be avoided that due to excessive dependency on experience, different researchers construct the model at different levels.
