| 6886740 | Apparatus for calculating time periods A single axis rotatable disc calendar for calculating time periods and future dates based on current or past events is disclosed. In particular, calculators for determining fertility timing, testing and treatment dates have a base circular calendar (61) and o... | 05/03/2005 |
| 6832324 | Method for providing a device communicating to a backplane the current status of an associated power supply unit connected to the backplane A power supply unit controller for a rack enclosure in which a plurality of devices communicate via a backplane is disclosed. The controller reads signal(s) indicative of output supply level(s) being provided to the backplane by a power supply unit associated the th... | 12/14/2004 |
| 6824785 | Skin treatment composition and methods of use A composition which when topically applied to the skin of a mammal reduces trans-epidermal water-loss and provides an improved epidermal barrier contains an aqueous dispersion of at least two lipids, preferably at least three lipids, in a non-crystalline phase lamel... | 11/30/2004 |
| 6706846 | Method for end-capping polycarbonate resins and composition for use in same A method for end-capping polycarbonate resins, comprising the step of processing a mixture comprising a polycarbonate having free hydroxyl-end groups and an end-capping reagent in a melt transesterification reaction to produce a polycarbonate resin, wherein the end-... | 03/16/2004 |
| 6667798 | Method and device for determining spatial positions and orientations Using a laser-tracker (1) with an interferometer together with a retroreflector (3) in the form of a triple prism or a triple mirror arranged on an object and designed for parallel reflection of the laser beam (5) directed to the reflector (3), the positi... | 12/23/2003 |
| 6599966 | Polycarbonate-polyester compositions with enhanced flow A molding composition comprising (a) from 10 to 90 weight percent of a polyester resin; (b) from 90 to 10 weight percent of an aromatic polycarbonate, polyarylate, polyester carbonate resin or blend thereof; and (c) a flow improving amount of lignin and/o... | 07/29/2003 |
| 6497959 | Use of dendrimers as a processing aid and surface modifier for thermoplastic resins Dendrimer additives incorporated in thermoplastic resins (such as polycarbonate resins) are effective to alter the surface characteristics of the thermoplastic resin. Such compositions can be injection molded to produce articles in which the dendrimer add... | 12/24/2002 |
| 6486871 | Pointing device with Z-axis functionality and reduced component count Apparatus and method are disclosed for receiving human input by means of a pointing device, typically a strain gauge.
