A miniature surgical robot and a method for using it are disclosed. The miniature surgical robot attaches directly with the bone of a patient. Two-dimensional X-ray images of the robot on the bone are registered with three-dimensional images of the bone. This locates the robot precisely on the bone of the patient. The robot is then directed to pre-operative determined positions based on a pre-operative plan by the surgeon. The robot then moves to the requested surgical site and aligns a sleeve through which the surgeon can insert a surgical tool.

An audio fingerprint is extracted from an audio sample, where the fingerprint contains information that is characteristic of the content in the sample. The fingerprint may be generated by computing an energy spectrum for the audio sample, resampling the energy spectrum logarithmically in the time dimension, transforming the resampled energy spectrum to produce a series of feature vectors, and computing the fingerprint using differential coding of the feature vectors. The generated fingerprint can be compared to a set of reference fingerprints in a database to identify the original audio content.

A method of detecting the state of an operator of a vehicle utilizes a low-cost operator state detection system having no more than one camera located preferably in the vehicle and directed toward a driver. A processor of the detection system processes preferably three points of the facial feature of the driver to calculate head pose and thus determine driver state (i.e. distracted, drowsy, etc.). The head pose is generally a three dimensional vector that includes the two angular components of yaw and pitch, but preferably not roll. Preferably, an output signal of the processor is sent to a counter measure system to alert the driver and / or accentuate vehicle safety response.

A one-dimensional LUT has been incapable of color matching. A three-dimensional LUT has been incapable of ensuring a color conversion accuracy enough to reproduce fine changes in color tone on a monochrome image. It has been impossible to suppress a storage capacity for a color conversion table by ensuring the accuracy. There is provided a color conversion table which has a plurality of pieces of reference color image data making correspondence between color data for a first image device and color data for a second image device and comprises a specified total information amount. The color conversion table is used to distribute the reference color image data over a prescribed area in a specified color space. Color data information for each reference color image data is increased more than a specified amount within a limit of the specified total information amount. Further, a color conversion table is created using an original table which highly accurately defines colors in part of the color conversion table. If these color conversion tables are referenced for color conversion, it is possible to suppress the storage capacity, provide color matching, and perform high accuracy color conversion.

In the case of a method for producing a fluid device with a fluid structure having an active height, a basic wafer is provided, which comprises a supporting substrate, an insulating layer on the supporting substrate and a patterned layer on the supporting substrate, the thickness of the patterned layer determining the active height of the fluid structure. Following this, the fluid structure is produced in the patterned layer of the basic wafer, said fluid structure extending through the semiconductor layer. A transparent wafer is then applied so that the fluid structure is covered. Subsequently, the supporting substrate and the insulating layer are removed from the back so that the fluid structure is exposed at a second surface of the patterned layer. Finally, a second transparent wafer is attached to the exposed second surface of the semiconductor layer so that the fluid structure is covered. The essential parameter of the fluid device, viz. the active height of the fluid structure, need no longer be controlled making use of the etching parameters, but is already determined by the specifications of the starting material, e.g. an SOI wafer. This means that economy-priced fluid devices can be produced with high precision.

Methods, apparatus and computer program products can generate light weight but highly realistic and accurate colored models of three-dimensional colored objects. The colored model may be generated from a second plurality of points that define a coarse digital representation of the surface and at least one texture map containing information derived from a first plurality of colored points that define a fine digital representation of the surface. This derivation is achieved by mapping points within the texture map to the fine digital representation of the three-dimensional surface. Colored scan data may be used to construct the fine digital representation as a triangulated surface (i.e., triangulation) using a wrapping operation. This triangulated surface may be a two-manifold with or without nonzero boundary and the colored scan data may constitute raw point data with each datum comprising three real numbers (x-,y-, z-coordinates) providing geometric information and three integer numbers (r-,g-,b-values) providing color information. Operations are then performed to create the coarse digital representation from the fine digital representation and also preferably create a plurality a texture maps from the fine and coarse digital representations. One map may contain color information and another map may recover geometric detail lost in the simplification process associated with generating the coarse digital representation from the fine digital representation. An additional map may also be generated that corrects for differences in directions of normal vectors associated with the coarse and fine digital representations.
