Title: Improved pulsed operation method for a silent discharge lamp
Inventor: VOLLKOMMER FRANK
IPC: H05B41/00
Filed: 2001-01-09
Abstract: The invention improves an operating method, already described in the prior application 198 39 329.6, for a silent discharge lamp L, in which, using the forward transformer principle, a voltage pulse effecting a forward ignition is impressed from a primary circuit P via a transformer T into a secondary circuit S containing the silent discharge lamp L, and the secondary circuit S thereafter executes a half wave which, as a consequence of the polarization, leads to a back ignition in the discharge lamp L. The improvement consists essentially in that an inductance of the transformer T which governs a transformer current is temporally varied.

Title: System and method for managing bi-directional relationships between objects
Inventor: YORKE GORDON JAMES
IPC: G06F17/30
Filed: 2002-08-14
Abstract: A bi-directional relationship manager is described for setting a new reference value for managing bi-directional relationships between objects in an object model. The bi-directional relationship manager receives bi-directional relationship information indicating interrelation between objects having one or more bi-directional relationships. It creates proxy objects based on the bi-directional relationship information for selected bi-directional relationship objects having bi-directional relationships. A created proxy object receives a new reference value to be set in a selected object relating to a bi-directional relationship. It determines, using one or more of the proxy objects, a new peer value to be set in a peer object which has the bi-directional relationship with the selected object, and sets the new peer value to a proxy object created for the peer object.. It may also update reference values of other related objects that are related to the selected object through one or more bi-directional relationships to reflect the change in references.
