Title: Method and system for implementing software objects
Inventor: MCDONALD MARC B
IPC: G06F9/44
Filed: 1996-10-16
Granted: 2003-08-12
Abstract: The present invention provides a new system for implementing software object s using an object-prototype model. Objects are defined as collections of properties, each having a unique property name. A collection of property nam es defines a "shape". The use of shapes frees the representation of an object i n memory from the order in which the properties of the object are declared. Methods are defined independently of objects and are applicable to a specifi ed shape, rather than to objects that are derived from a class in which the method is defined. Methods can be applied to any object that has the specifi ed shape or that has a superset of the properties defining the specified shape,  regardless of the place of the object in any inheritance hierarchy. The definition of a shape can also include additional selection criteria, such a s restrictions on the values of properties, so that the application of a metho d can be restricted to objects satisfying the specified criteria. The properti es of objects can be divided into subgroups representing different aspects of t he object and different subgroups of an object can be inherited from different parent objects, based upon either a has-a or an is-a hierarchy. The shape of  an object is determined by all of its properties and is not confined by subgroup boundaries.

Title: Nucleic acid vaccination for parvoviral infections
Inventor: SCHORR JOACHIM
IPC: C12N15/09
Filed: 1997-04-18
Granted: 2011-12-20
Abstract: The general field of the invention is a method for nucleic acid vaccination of animals to protect them from parvoviral infections. This invention is more particulary related to the preparation and use of parvoviral DNA and its administration to dogs, cats and mink so as to induce an immune response that can protect these animals from disease caused by virulante parvovirus. Nucleic acid immunogens are designed to include the antigenic portions of the parvoviral genome which are incorporated into bacterial plasmids. These plasmids produce the desired parvoviral gene product when introduced into host cells by transfection. Host cells transfected with the parvoviral immunogen expressing plasmids produce a stream of antigenic proteins to which the host immune system will mount a protective immune response.

Title: Fluid pump control apparatus and method
Inventor: HARADA YASUO
IPC: F02M63/02
Filed: 1999-01-18
Granted: 2003-04-08
Abstract: An apparatus and a method control an amount of pressurized fluid to be pumped by a high-pressure fluid pump to a common rail, by using a control circuit (ECU), in order to improve the controllability of the fluid pumping amount of the fluid pump. The ECU sets a base fluid pumping amount based on a target value of pressure in the common rail and an amount of fluid ejected from the common rail. The ECU also calculates a fluid pumping amount required to cause the actual pressure of the common rail to follow a change of a target pressure of the common rail on a basis of an amount of change of the target pressure. The ECU sets the sum of the basic fluid pumping amount, the required fluid pumping amount and a earned-over amount of fluid, as a set value of the fluid pumping amount. If the set value of the fluid pumping amount exceeds a predetermined capacity of the fluid pump, the ECU sets a difference between the set value of the fluid pumping amount and the predetermined capacity as the carried-over amount of fluid that is carried over to a next setting of fluid pumping amount, thereby reflecting the difference therebetween in a next set value of the fluid pumping amount.
