摘要： A face milling insert comprising a pair of main cutting edges which are spaced apart from a center and meet at a corner where they transform into a surface wiping secondary edge, which is intersected by a bisector defining the corner between the main cutting edges, inside each main cutting edge a slope surface being formed, which slopes towards a countersunk bottom surface in a chip surface. A shoulder, having a top side situated at a higher level than the bottom surface, extends inwardly from the secondary edge, the slope surface of the main cutting edge that actively co-operates with the secondary edge, terminating at the shoulder.

摘要： The present invention addresses the problem of a second (or higher) order representation of a transmit signal which is transmitted by a transceiver being mixed into the region of the frequency spectrum of interest to the transceiver receiver, such that it can not then be spectrally filtered out. At its most straightforward, in one embodiment of the invention this is achieved by providing a cross-talk cancellation unit which takes the transmit signal, and obtains the second (or higher) order representation thereof. This representation is then subtracted from the received signal before the signal is passed to the radio control receiver signal processing elements. However, in a more preferred arrangement a filter is also provided, to filter the second or higher order version of the transmit signal, prior to its being subtracted from the received signal. The filter basically takes out the effects of any other filtering or processing which has happened to the transmit signal in the receiver signal chain. This would be, for example, the filtering effects provided by the anti-aliasing filter in the receiver.

摘要： A method and apparatus for aligning I- and Q-signals in a quadrature receiver based on an squared signal. A correction is evaluated in an iterative manner by finding an average of the squared signal. The average squared signal may be the received signal, in which case the iterations are applied in a feed forward manner. Alternatively, the average squared signal is the aligned signal in which case the iterations are applied in a feed back manner. The correction may include the evaluation of an normalization or, in the feed back case, this can be implicitly included in the manner in which the iteration is applied. Various parameters to the iteration can be set to accommodate the operating environment of the receiver and characteristics of the received signal.

摘要： An indexable end-milling insert including an underside, an upperside and a plurality of cutting edges that are formed between the upperside and a number of clearance sides and that include a chip-removing main edge as well as a surface-wiping wiper edge. The cutting insert has a square basic shape and includes four main edges and four wiper edges that are countersunk to a lower level than the main edges. The wiper edge is included in a lip projecting in relation to a secondary clearance surface and has a tertiary clearance surface, which laterally transforms into a primary clearance surface. The primary clearance surface has a width that decreases from the two opposite ends thereof toward a section having a smallest width therebetween.

摘要： The invention relates to a milling tool intended for chip-removing machining, comprising a basic body rotatable around a geometrical centre axis and a plurality of peripherically spaced-apart, detachable cutting inserts, which separately are securable in insert pockets adjacent to chip channels formed in the basic body, the individual cutting insert having at least one edge formed between a chip surface on the top side of the cutting insert and a clearance surface along the periphery side of the cutting insert, the tool geometry being markedly positive so far that the individual insert pocket is arranged to secure the individual cutting insert in a position in which the chip surface is inclined in relation to the centre axis while forming a positive angle of inclination. Characteristics of the invention is the combination that the angle of inclination between the chip surface and the centre axis is within the range of 25-28°, that the cutting edge cross section-wise has an arc-shape having a radius of curvature (ER) within the range of 5-20 μm, that the clearance surface of the cutting insert is formed with a clearance bevel, which extends from the cutting edge in the direction of the bottom side of the cutting insert and transforms into a main clearance portion, that the clearance angle (γ) of the clearance bevel is larger than 0°, but smaller than 3°, that the clearance angle (γ) of the main clearance portion is larger than the clearance angle (γ) of the clearance bevel, that the extension of the clearance bevel from the cutting edge to the main clearance portion is within the range of 0.05-0.30 mm, that the chip surface is formed with a reinforcement bevel, which extends from the cutting edge in the direction of the centre of the cutting insert and transforms into a main chip portion, the angle of inclination of the reinforcement bevel in relation to the centre axis being larger than −5°, but smaller than +5°, and that the extension of the reinforcement bevel from the cutting edge to the main chip portion is within range of 0.05-0.15 mm. The invention also separately relates to a milling insert as well as a solid milling tool.

摘要： A detector for detecting a cardiac event in an IEGM has a bank of digital filters composed of at least two filters with substantially different impulse responses corresponding to different properties of the cardiac event. The filters respectively filter different portions of the IEGM and respectively emit a value per time unit corresponding to the morphological resemblance between the IEGM and the finite impulse response. An analyzing unit combines these output values from the filters in a predetermined manner for comparison with predetermined detection criteria.

摘要： An apparatus for detecting cardiac events in electrograms has a feature extraction unit that derives features of the cardiac events for discriminating among different types of cardiac events. A clustering unit groups cardiac events with similar features into respective clusters defined by predetermined cluster features. The feature extraction unit determines a feature vector describing waveform characteristics of cardiac events in the electrogram by a wavelet transform. The clustering unit determines the distance between the feature vector and corresponding cluster feature vectors in order to assign the cardiac event in question to that cluster which results in a minimum distance, providing that the minimum distance is less than a predetermined threshold value. A heart stimulator provided with such a cardiac event detecting apparatus detects the occurrence of an arrhythmia and appropriately controls a pulse stimulator to treat the arrhythmia.
