IPC: G06F17/30
Filed: 2003-04-30
Abstract: The invention improves performance of a query in a database system when a pl an for the query includes sorting an input that is at least partially sorted such that a slow materialization sort can be applied. The invention applies the slow materialization sort by determini ng a sequence of subsets in accordance with the partially sorted input. As each of the subset s is determined, the subset is output for further processing. Advantageously, the invention reduc es the waiting period for obtaining results from a sorting operation under certain circumstances.< /SDOAB>

Title: Security element
Inventor: STAUB RENE
IPC: B42D15/00
Filed: 2002-09-04
Abstract: A security element (2) in the form of a laminate can be used for the authentication of a document (1). The laminate has at least a transparent protective layer, a transparent lacquer layer and an adhesive layer, the lacquer layer being arranged between the protective layer and the adhesive layer. An interface in the form of a reflection layer separates the adhesive layer and the lacquer layer. The interface is divided into regions of a pattern (25) with flat surface portions and with relief structures which are formed in the lacquer layer. The flat surface portions form background surfaces (3) providing flat mirror surfaces for light which is incident into the laminate, while the regions with the relief structures of a predetermined, optically effective structure depth form pattern elements (4). The relief structures of the pattern elements (4) absorb the incident light. In the reflected light of the reflecting background surfaces (3) the dark pattern elements (4) form a strong contrast and the pattern (25) is clearly visible. In directions other than that of the reflected light the contrast between the background surfaces (3) and the pattern elements (4) disappears so that a copier apparatus reproduces the background surfaces (3) and the pattern elements (4) as black surfaces.

Title: Method and apparatus for ozone sterilization
Inventor: DUFRESNE SYLVIE
IPC: A61L2/20
Filed: 2002-11-08
Abstract: The sterilization method disclosed includes the steps of providing a sterilization chamber (10); - placing the article into the sterilization chamber; - equalizing the temperature of the article and the sterilization atmosphere; sealing the sterilization chamber; -applying a vacuum (40) of a preselected vacuum pressure to the sterilization chamber; - supplying water vapour (30) to the sterilization chamber under vacuum; - supplying ozone-containing gas (22) to the sterilization chamber; - maintaining the sterilization chamber sealed for a preselected treatment period; and -releasing the vacuum in the sterilization chamber; whereby a vacuum pressure is used which lowers the boiling temperature of water in the sterilization chamber below the temperature in the sterilization chamber. One or more ventilating cycles can be added to the preferred method for removing the remaining ozone and humidity from the sterilization chamber. Single cycle sterilization with ozone is more efficient and provides for a shorter sterilization cycle than with ETO and requires few changes in user habits.  Moreover, the ozone-based process in accordance with the invention is compatible for use with current packaging, such as sterile pouches and rigid containers. The sterilization process is simple and substantially avoids human errors caused by false interpretation and handling. The ozone sterilization method of the invention requires substantially no aeration or cooling down of sterilized instruments so that they can be used immediately following the sterilization cycle. This allows hospitals to reduce the cost of maintaining expensive medical device inventories.
