Abstract: The invention relates to sun protection installations comprising reflective sun protection lamellae consisting of portions having a toothed upper side disposed at least towards sun radiation influx wherein the individual teeth are formed of at least two tooth sides, and at least one first tooth side is, at least partly, exposed to sun light irradiation. Sun light irradiation, at least within the first lamella portions, can be retro-reflected by one single reflection into the outer space by the first tooth side having an angle of impact .alpha.1. The tooth angle of impact .alpha.1 of the tooth sides exposed to the sun light are so selected within the first lamella portions facing the irradiation area that in case of parallel sun light larger angles of impact .beta. of the sun radiation are obtained so that inciding sun light may be reflected back, by one single reflection, to the outer space.  Second or further lamella portions are so arranged at an angle .alpha.1 that small angles of impact .beta. on the tooth sides facing the sun will result but the sun light can be reflected into the interior space. In any case, tooth angles of impact .alpha.1 within the lamellae differ from each other.

Abstract: A service system provides substantially zero delay service and dynamically adjusts resources required to provide the service.      According to an embodiment of the present invention, future staffing requirements of the service system are predicted by determining, of a number of customers currently in service, how many will remain in service at a predetermined future time and how many customers to arrive to the system in the future can be expected to remain in service at the predetermined future time.      For customers in service, customers may be classified according to one or more attributes known for the customer. The attributes may be helpful to identify a type of service being provided to the customer and determine a remaining service time for the customer.      Thus, the customer attributes may provide for more accurate staffing predictions than in the prior art.

Granted: 2005-05-10
Abstract: An apparatus for the automatic delivery to an animal of a beneficial agent such as analgesia by infusion with the pain of the animal being taken into account when determining the rate of dispensing the agent. As the pain experienced by an animal and therefore its distress is manifested in increased agitation, the apparatus includes elements for the measurement of the frequency and amplitude of an animal's movement and the generation of a trigger signal when the either the frequency or the amplitude exceeds a predetermined threshold. The trigger can be used to generate a visual or audible alarm. The apparatus also preferably includes a dispensing means for delivering doses of beneficial agent to the animal in response to the trigger signal. The apparatus serves primarily to reduce the post-operative distress experienced by an animal by providing for timely administration of analgesic compounds. The apparatus also aids the animal care-giver by reducing the amount of time spent assessing the animal and administering beneficial compounds.

Abstract: A resource allocation manager to allocate resources to handle applications in a messaging system includes a database storing a set of resource allocation rules to govern the allocation of resources to applications. A resource allocation engine is responsive to events that potentially effect the manner in which resources are allocated. The resource allocation agent accesses the database and interprets the resource allocation rules in response to events to determine if the events warrant a reallocation of resources to handle applications. Allocation agents are responsive to the resource allocation engine and reallocate resources to handle applications when detected events warrant a reallocation of resources. A method of allocating resources in a messaging system is also provided.
