Abstract: The invention relates to a vertical turbine pump having a riser pipe extending along an axis, a motor shaft arranged in the riser pipe, an elbow housing with an elbow arranged therein and connected on a pressure side to the riser pipe, a lantern housing arranged on the elbow housing and accommodating the motor shaft, and a motor arranged on the lantern housing and driving the motor shaft, wherein the elbow housing and/or the lantern housing is formed mould-free and has a rectangular cross section.

Abstract: A bearing arrangement for guiding a motor shaft for supporting axial and/or radial forces of a vertical turbine pump. The bearing arrangement includes a bearing comprising an inner ring which can be non-rotatably connected to the motor shaft and an outer ring, an oil sump filled with an oil, within which the bearing is arranged at least partially immersed in the oil, and an inner oil deflector which is non-rotatably connected to the inner ring and deflects oil conveyed between the inner ring and the outer ring back into the oil sump as a result of rotation of the bearing.

Abstract: A method for programming a hearing device is described, in which audio data and programming data is transmitted from a programming device to the hearing device, with the audio data and the programming data being converted into data packets and transmitted via a common channel of a digital radio connection from the programming device to the hearing device.

Abstract: A method for identifying hearing aids is described wherein a wireless connection is established between a control device and at least one unidentified hearing aid, and which comprises the following procedural steps: a request is sent by the control device to at least one unidentified hearing aid; the request is received by the hearing aid addressed; a response is provided in the hearing aid addressed, whereby the response contains an individual identifier of the respective hearing aid; and the response is sent by the hearing aid addressed to the control device, whereby the response is transmitted at a point in time that is individually determined by the responding hearing aid.

Abstract: The present invention provides a method for parallel optimization of an integrated circuit design based on the use of sets of cell instances that are independent from each other. Multiple changes to a design are analyzed in parallel by ensuring that no two cell instances that are being changed are in the same fan-in and fan-out cones. This property allows full timing analysis to be performed on a design such that multiple alternatives are explored in parallel and accurate results are obtained. By ordering the choice of cell instances to change and by ordering the alternatives to try, a greater degree of optimization is found earlier in the process.

Abstract: The present invention comprises a method of optimizing a circuit design having a plurality of library cells. In one embodiment, the method includes the steps of providing a plurality of logically equivalent cells that vary in at least one design parameter, the plurality of logically equivalent cells having a relatively continuous spectrum of values of one of the design parameters, evaluating a selected characteristic of the circuit design; and replacing a cell in the circuit design with a cell an equivalent cell.

Abstract: A method and apparatus for optimizing a circuit design using a library of cells in which a continuous spectrum of cells are provided. A library containing real and virtual cells is used so that cells can be selected across a wide spectrum of a design parameter, such as drive strength. The cells are provided in discrete steps small enough that the effect of having a continuous spectrum of cells is achieved. After optimization, only the cells finally selected need be actually synthesized, and when these constitute a small percentage of the total number of cells, the impact to library size and final placement and routing is minimized. Thus the ability to optimize across a continuous spectrum is achieved while preserving a cell library based design flow.
