| 20110260782 | ELECTRONIC CIRCUIT WITH A REGULATED POWER SUPPLY CIRCUIT - A power supply regulator circuit uses a feedback loop to control current through a first output transistor from a power supply input to a regulated power supply output. The first output transistor is included in an integrated circuit. In order to avoid heating of the integrated circuit in excess of an acceptable level due to permanent supply of a high current through the first transistor, current through a second output transistor in parallel with the first transistor, but outside the integrated circuit is raised when it is detected that the current through the first output transistor exceeds a threshold level. The second output transistor outside the integrated circuit serves to take over supply of a part of the power supply current from first output transistor inside integrated circuit, when long term supply of that part from first output transistor would lead to undesirable heating of the integrated circuit. During a limited time interval a first transistor current above the threshold level is acceptable. During this time interval the current through the second output transistor is raised slowly in order to avoid unpredictable stability problems and the generation of excessive power supply noise. | 10-27-2011 |

| 20080250416 | Linking of Scheduling Systems for Appointments at Multiple Facilities - Scheduling systems for scheduling appointments on multiple sites need to be linked, if such systems use different databases. The activity to be performed by the performing site during the appointment may be given by a requesting code, specific for the requesting site. If the activity can be performed at the requesting site, i.e. the requesting site and the performing site are identical, then this “requesting code” may define that one or more resources are required for performing the scheduled appointment at the requesting site. The availability of these resources can be fetched from one or more databases coupled to the requesting site. If the performing site is different from the requesting site, the requesting code used at the performing site for the activity may be different from the requesting code used at the requesting site, and different resources may be requested by the performing site. The availability of these different resources may be stored in one or more databases, different from the databases for resources at the requesting site. In the latter case, both the requesting site and the performing site keep records of the scheduled appointment e.g. in a respective database. If a person, for whom the appointment is made, is known at the requesting or performing site or both, person occupation checking may be done at either site or both. | 10-09-2008 |
