Title: Method for measurement of skin histology
Inventor: COTTON SYMON D OYLY
IPC: A61B5/103
Filed: 1997-11-19
Granted: 2006-02-07
Abstract: The invention relates to a method for non-invasively measuring skin structure.  Infrared radiation from a plurality of locations over an area of skin under investigation is measured so as to give an indication of the variation in papillary dermis thickness over said area, and the skin colour coordinates at a plurality of locations over the same area of skin is also measured. The data obtained is used to calculate corrected skin colour coordinates over the area corresponding to a predetermined papillary dermis thickness. The corrected skin colour coordinates so obtained are compared with a reference colour coordinate range for healthy skin of the same predetermined papillary dermis thickness. At an abnormal region, where the corrected skin colour coordinates lie outside the reference colour coordinate range, the depth of penetration of dermal melanin can be measured.

Title: Selectivity estimation for processing sql queries containing having clauses
Inventor: HAAS PETER J
IPC: G06F17/30
Filed: 2000-04-28
Granted: 2004-05-25
Abstract: The estimate of the selectivity of a HAVING clause in an SQL query is carried out by within a specified time constraint by determining a selectivity estimate for each member in a sample set of group sizes for the HAVING clause using a probabilistic model based on an assumed value distribution. The selectivity estimates for the groups in the sample set are used to interpolate estimates for all possible group sizes and the estimates are combined based on an assumed known group size distribution to provide an estimation of the selectivity for the HAVING clause. Different selectivity estimating approaches are used for each group size based on available time for estimating and on the estimated time to complete the estimate using different techniques.

Abstract: The invention relates to a method for the highly accurate determination of the filling level (q) of a product (4) in a container (2), measuring signals being transmitted in the direction of the surface (5) of the filled product (4) and reflected at the surface (5) as echo signals and the filling level (q) in the container (2) being determined by evaluation of the amplitude values (A) and phase values (.PHI.) of the reflected echo signals by means of a pulse delay-time method.      Furthermore, an apparatus suitable for carrying out the method is proposed.      The invention is based on the object of proposing a method and an apparatus which permit highly accurate filling level measurements in containers (2), even if multipath propagation or multimode propagation occurs.      The object is achieved by compensating for errors which occur in the determination of the filling level (q) and are caused by interference signals which interfere constructively or destructively with the echo signals reflected regularly at the surface (5) of the filled product (4).

Abstract: The gas separator is provided with a substrate portion having a predetermined concave-convex shape, an underlying coating layer formed on the substrate portion, a first coating layer for coating the substrate portion and the underlying coating layer, and a second coating layer formed thereon. The second coating layer is formed from a carbon material, and is sufficiently conductive. Moreover, the second coating layer protects the underlying layer. The first coating layer is formed from a noble metal. Therefore, the first coating layer coated with the second coating layer exhibits extremely high corrosion resistance. The underlying coating layer and the substrate portion are coated with the f first and second coating layers, so that the progress in corrosion can be sufficiently prevented. Thus, excellent overall corrosion resistance of the separator can be realized.

Abstract: The air pressure sensor of the present invention functions to control the water level in a washing machine tub and to vary the fill volume relative to the clothes load. The sensor or switch is mounted on the drain pump on the base of the washing machine cabinet, so as to be independent from the washing machine tub.      An air dome extends between the switch and the water inlet line of the pump. The switch is set to be actuated at a predetermined pressure. As the water level increases in the tub, the air pressure within the air dome increases, until eventually the switch is actuated. The switch is mounted directly to,the air dome in an angular orientation, thereby minimizing or eliminating condensation problems in the switch. The switch will also be activated by water pressure, in the event of an air leak in the air dome, so as to preclude water overflow of the tub.

Title: Retrieval device made of precursor alloy cable
Inventor: MCALISTER GARY B
IPC: A61B17/221
Filed: 2000-10-26
Granted: 2008-07-29
Abstract: A medical retrieval device for retrieving foreign objects from a patient and the method of constructing the device are disclosed. The device incorporates a wire cable composed of a precursor alloy to a superelastic material to improve durability of the device. Because precursor alloys exhibit a linear stress-strain relationship and a yield point associated with a relatively high stress level, the device transfers greater stresses before experiencing deformation. Thus, greater crushing forces can be achieved using a device of this type. These crushing forces may be needed when the foreign object is too large to remove intact. This property also facilitates the device in dilating ducts to retrieve foreign objects. Using the precursor alloy additionally eliminates the need for heat treatment of the cables used in constructing the device. A retrieval device made of precursor alloy cable also is less susceptible to permanent deformation and unwinding during use.
