Chip stacks with decreased conductor length and improved noise immunity are formed by laser drilling of individual chips, such as memory chips, preferably near but within the periphery thereof, and forming conductors therethrough, preferably by metallization or filling with conductive paste which may be stabilized by transient liquid phase (TLP) processes and preferably with or during metallization of conductive pads, possibly including connector patterns on both sides of at least some of the chips in the stack. At least some of the chips in the stack then have electrical and mechanical connections made therebetween, preferably with electroplated solder preforms consistent with TLP processes. The connections may be contained by a layer of resilient material surrounding the connections and which may be formed in-situ. High density circuit packages thus obtained may be mounted on a carrier by surface mount techniques or separable connectors such as a plug and socket arrangement. The carrier may be of the same material as the chip stacks to match coefficients of thermal expansion. High-density circuit packages may also be in the form of removable memory modules in generally planar or prism shaped form similar to a pen or as a thermal conduction module.

A method and system in a portable computer having a display screen for increasing portable computer compactness. Data is displayed initially within the display screen. The display screen is then partitioned into a touch-sensitive input area and a display area, wherein data input at the touch-sensitive input area may be simultaneously displayed in the display area, in response to a particular user input. A test is performed to detect if a user's hands are positioned at the touch-sensitive input area. A touch-sensitive pad is thereafter graphically displayed at the touch-sensitive input area within the display screen, in response to detecting a user's hands positioned at the touch-sensitive area, wherein a user may enter data that may be simultaneously displayed in the display area. An additional test may then be performed to detect if the user's hands are no longer positioned at the touch-sensitive input area. The touch-sensitive pad is subsequently concealed from view, in response to detecting if the user's hands are no longer positioned at the touch-sensitive input area. The touch-sensitive pad graphically displayed at the touch-sensitive input area within the display screen may be composed of a touch-sensitive keyboard, which may in and of itself be an ergonomic keyboard.

The present invention provides a rolling bearing fault diagnosis method in various working conditions based on feature transfer learning, and relates to the field of fault diagnosis. The objective ofthe invention is to solve the problem that a rolling bearing, especially to various working conditions, is low in accuracy of diagnosis. The method comprise the steps of: employing a VMD (VariationalMode Decomposition) to perform decomposition of vibration signals of a rolling bearing in each state to obtain a series of intrinsic mode functions, performing singular value decomposition of a matrixformed by the intrinsic mode functions to solve a singular value or a singular value entropy, combining time domain features and frequency domain features of the vibration signals to construct a multi-feature set; introducing a semisupervised transfer component analysis method to perform multinuclear construction of a kernel function thereof, sample features of different working conditions are commonly mapped to a shared reproducing kernel Hilbert space so as to improve the data intra-class compactness and the inter-class differentiation; and employing the maximum mean discrepancy embedding to select more efficient data as a source domain, inputting source domain feature samples into a SVM (Support Vector Machine) for training, and testing target domain feature samples after mapping. Therolling bearing fault diagnosis method in various working conditions has higher accuracy in the rolling bearing multi-state classification in various working conditions.

A method and apparatus use a photonic-crystal fiber having a very large core while maintaining a single transverse mode. In some fiber lasers and amplifiers having large cores problems exist related to energy being generated at multiple-modes (i.e., polygamy), and of mode hopping (i.e., promiscuity) due to limited control of energy levels and fluctuations. The problems of multiple-modes and mode hopping result from the use of large-diameter waveguides, and are addressed by the invention. This is especially true in lasers using large amounts of energy (i.e., lasers in the one-megawatt or more range). By using multiple small waveguides in parallel, large amounts of energy can be passed through a laser, but with better control such that the aforementioned problems can be reduced. An additional advantage is that the polarization of the light can be maintained better than by using a single fiber core.
