Abstract: Embodiments relate to a communication system comprising a call handler arranged to process channel signalling received from a communication network; a workload controller comprising means to determine the workload of at least one processing resource of the communication system; wherein the call handler comprises means to block establishment of at least one channel in response to the workload of the at least one processing resource.

Abstract: According to one embodiment of the present invention there is provided a communication method comprising the steps of making a determination in respect of at least initiating a first call between first and second communication devices having first and second contact numbers respectively; said making the determination comprising identifying at least one of the first and second contact numbers associated with said initiating, accessing a database comprising at least a first monitored contact number and at least one associated third party number corresponding to a third communication device, determining whether or not at least one of a first contact number and the second contact number match the first monitored contact number; and establishing, in response to the determination, a third party call to the third communication device.

Abstract: In a computer system with a virtual addressing mechanism, a process for the de-allocation of physical pages sets, by means of a first pointer (ptr) on a line (5) of a conversion table (1) that contains an indicator (Ref) that has been set to a first state (“referenced”) by a processor (2), the indicator (Ref) to a second state (“non-referenced”) if the state is (“referenced”) and de-allocates the line (5) if the state is (“non-referenced”). The de-allocation process claimed by the invention sets an indicator (ref) which has been set to the first state (“referenced”) by the processor (2) on a line (13) of the conversion table (1) to a second state (“non-referenced”) if the state is (“referenced”) by means of a second pointer (ptr+&Dgr;) on the line (13) upon the indication of an attribute value (Co) for said line (13). The de-allocation process can therefore be used for a cache mechanism.

Abstract: A probe comprising a casing of which one face which will be in contact with the skin is providied with an aperture, is connected to a measuring device by means of a flexible connection in fiber optics comprising at least three optical conductors which, at a first end, are secured in the casing of the probe such as to face the aperture thereof, the first and second conductors having their first end portions directed respectively in a first and a second directions which are symmetrical to each other with respect to an axis extending normally through the aperture, while the third conductor has its first end portion directed in another direction than said second direction.
