Porous medical device and method for its manufacture

ActiveUS7964206B2Thickness of device can be variedControllable porosityBiocideGenetic material ingredientsFiberBioceramic
Porous bioabsorbable, bioactive and load-bearing composite medical device structure includes a plurality of regular textile planar layers (1a, 1b . . . ) formed of continuous bioabsorbable polymer matrix and bioceramic fibers acting as reinforcements, both included in continuous fibrous elements (3) forming the textile layers. The layers are placed on top of each other to form a structure having two dimensions (x, y) at right angles to each other according to the two dimensions of the textile layer and a third dimension (z) perpendicular to them and resulting from the piling of the layers. A plurality of passages extend through the layers as a result of the openings (2) defined by portions of the continuous fibrous elements (3) extending substantially in the direction of the plane. The continuous fibrous elements (3) comprise both bioactive ceramic reinforcing fibers which form a reinforcing structure and a bioabsorbable polymer matrix material which forms a matrix which binds the layers together and also binds the portions of continuous fibers defining the openings together, thereby forming the passages and stiffening the structure. This bioactive and bioabsorbable composite structure is suitable to be used as a basic structure in medical devices, especially in osteochondral applications where the load-bearing properties of implant are required.

Method of correcting measurement error and electronic component characteristic measurement apparatus

A high-precision, multi-port compatible, relative correction method and apparatus for correcting measurement errors covering an increase in the number of ports of a non-coaxial electronic component, in which a relative correction adapter 31 is provided that is formed of a two-port network connected to each port of a production test fixture 5B adjacent to a measurement apparatus. The relative correction adapter has a characteristic that modifies the electrical characteristics generated by the production test fixture 5B having an electronic component under test mounted thereon into electrical characteristics generated by a standard test fixture 5A having the electronic component under test mounted thereon. An error factor of the relative correction adapter 31 is identified from a standard test fixture measurement value and a production test fixture measurement value of a correction data acquisition specimen 11B. A production test fixture measurement value of the electronic component under test 11A is corrected with the error factor of the relative correction adapter 31 to thereby obtain the standard test fixture measurement value of the electronic component under test 11A which is assumed to be obtained when the electronic component under test 11A.

Method for variability constraints in design of integrated circuits especially digital circuits which includes timing closure upon placement and routing of digital circuit or network

In a standard cell, dummy transistors have p-type and n-type dummy gate electrodes. The dummy transistors are in an OFF state all the time. The gate length of each of the dummy gate electrodes is extended over an end portion of a diffusion region toward the inside of the standard cell. Thus, the total surface area and the total perimeter of respective gate electrodes of all transistors provided in the standard cell are increased. As a result, for example, even though shapes of gate electrodes of transistors vary between the standard cell and each of other standard cells, transistor characteristics are substantially equal among the standard cells. Therefore, variations in delays of signals generated between the standard cells can be suppressed.

Radar system with phase based multi-target detection

A radar system includes a plurality of antennas and a controller. The plurality of antennas is configured to detect a reflected radar signal reflected by an object in a field-of-view of the system. Each antenna of the plurality of antennas is configured to output a detected signal indicative of the reflected radar signal detected by the antenna. The controller is configured to receive detected signals from the plurality of antennas, and determine if a target is present in the field-of-view based on the detected signals. The controller is also configured to determine if the target includes more than one object based on an analysis of phases of the detected signals.
