Abstract: The invention relates to a method for the calibration of a radiation sensor, in which method a first calibration takes place with external radiation x and an internal signal s of the radiation sensor, and in which later calibrations are carried out exclusively with the internal signal. This enables the calculation of an approximate value x*(t) for the quantity of radiation x(t) absorbed in a radiation sensor (10) while taking into account a behavior of the radiation sensor that changes in time. First the primary characteristic ft1(x) is measured at a first instant t1; this characteristic describes the dependency of an output signal o on the absorbed quantity of radiation x. At the same time the secondary characteristic gt2(s) is measured, which characteristic describes the dependency of the output signal o on an internal signal s. The signals s and x should together form an intermediate signal w that is further processed with a function D(w,t) that varies in time in order to form the output signal o.

Abstract: A unit which allows a data transmission device such as a modem or FAX to be connected to a telephone line that is employed as the communication channel for a supervised alarm system. The poll and poll response signals and low-tone associated with a supervised alarm system would interfere with the data signals flowing to and from a modem/FAX if allowed to be present on the telephone line simultaneously. The present invention will disconnect a modem/FAX from the telephone line during data transmission if an alarm condition arises, by monitoring the low tone status of the alarm system. A low tone filter is provided to improve data transmission and connection speeds. Low tone attenuation is synthesised by the present invention to indicate off-hook status to alarm monitoring equipment at the telephone exchange.

Abstract: A device for redirecting alarm-messaging from an alarm control panel from its connection to the PSTN to a backup radio transceiver for transmission of the alarm signaling to a central alarm station via a radio network. The switch-over to the radio network occurs not only when the PSTN line is down, for whatever reason, but also occurs when the PSTN line is already occupied by an existing transmission by a premises' telephones, in order to allow the user to make a call over the PSTN during such an alarm condition. Moreover, if during the time the alarm control panel is transmitting its alarm messages over the PSTN, a premises' telephone goes off-hook, the device of the invention terminates the alarm panel's connection to the PSTN and automatically switches over the alarm panel to the radio backup system.

Abstract: When a Java application AP originates a call to a certain communication node, a Java application manager JAM refers to the history of outgoing/incoming calls and telephone directory data mentioned above to determine whether the call origination processing should be granted by checking whether the telephone number of the communication node, for which call origination is to be implemented, is included in the history of outgoing/incoming calls or the telephone directory data. The determination is based on an idea in which, if the telephone number of the communication node for which call origination is to be performed is included in the history of outgoing/incoming calls or the telephone directory data, then the call origination processing is valid on a basis of the recognition in that a portable telephone has performed communication with the communication node in the past or the user has recognized it as a communication partner.

Abstract: A variant on the ‘One Time Pad’ cipher is used to provide an encrypted link between two or more stations. The main feature of this variant is the use of a unique and easily created Pseudo-Random Number Sequence segment not having any internal repeats. At one station, a mixing function is used to combine a locally created stream of truly random bytes with a portion of this unique PRNS segment, yielding a fresh stream of truly random data. This freshly created stream of truly random data is operated on in such a way as to create a new and unique PRNS element set which is used to control the functioning of a PRNS generator. The PRNS generator is used to create a new and unique PRNS segment which has a repeat period much longer than the length of the PRNS element set used to create it. It is then useful to treat the PRNS element set as a message and transfer it across the encrypted link to other stations.
