Abstract: A processor may utilise two operating systems (Non-Secure, Secure) between which calls may be made. In order that a second operating system can track task switches made by a first operating system, each time a call is made to the second operating system, this call includes an identifier to enable discrimination between the task which was executing on the first operating system when that call was made. The identifier can be a call identifier and/or a target thread identifier and may include further parameters.

Abstract: The present invention provides an electrode, typically an anode, for use in an x-ray generating apparatus comprising an electron source. The electrode comprises a housing, a diamond member mounted to the housing, and a target located on the diamond member, which target in use is bombarded with electrons from the electron source so as to generate x-rays. A bonding layer is located between the housing the diamond member, which bonding layer comprises an alloy having a solidus or melting point of less than 900° C. A particularly preferred alloy comprises silver, copper and indium. This arrangement assists in dissipating heat generated at the electrode surface whilst retaining the structural integrity of the electrode.

Abstract: A charged particle (e.g. photoelectron) spectrometer is operable in a first mode to produce an energy spectrum relating to the composition of a sample being analysed, and in a second mode to produce a charged particle image of the surface of the sample being analysed. A detector is used to detect charged particles produced in both modes of operation. A method of operation of the spectrometer includes the step of selecting which of said first and second modes to use and the detector being operated accordingly.

Abstract: In a data processing system using multiple operating systems, an interrupt which itself may be interrupted by a subsequent interrupt which will be serviced in a different operating system, guards itself against being overlooked when that subsequent interrupt has been handled by starting a stub interrupt handling routine in that other operating system before executing the main handling routine in the originating operating system. Thus, the stub interrupt handling routine will be recognised in the other operating system irrespective of other interrupt events which may occur and accordingly the interrupted interrupt handling may be restarted.

Abstract: A data processing system includes a processor that can operate in a plurality of modes and in either a secure domain or a non-secure domain. At least one secure mode is a mode in the secure domain, and at least one non-secure mode is a mode in the non-secure domain. When the processor is executing a program in a secure mode and that program has access to secure data which is not accessible when the processor is operating in a non-secure mode, the processor is responsive to exception conditions for triggering exception processing. Specifically, the processor is responsive to a parameter specifying which of the exceptions should be handled by a secure mode exception handler executing in a secure mode and which should be handled by an exception handler executing in a mode within a current one of the secure domain and the non-secure domain when that exception occurs.

Abstract: A method of determining the location in time of maxima and/or minima of an oscillatory signal. The method may have application to measurement of biological signals, in particular measurement of heart rate from a pulsatile blood signal. The method includes a first stage including the steps of observation over a measurement period, identifying large local maxima or minima and computing an average interval between the identified local maxima or minima. One or more exclusion periods are located in time in the oscillatory signal, having a duration dependent on the average interval, the exclusion periods used to reject false maxima or minima. Maxima or minima may also be detected as an absolute maximum or minimum between crossing points of a fast and a slow moving average of the oscillatory signal. An exclusion period may also be used to reject false maxima or minima when crossing points are used. Apparatus for performing the method is also claimed.

Abstract: In a system supporting more than one operating system, a data processing thread executing on a first operating system may be subject to an interrupt which triggers interrupt handling on a second operating system. When that interrupt handling is completed on the second operating system, the first operating system is resumed using a return interrupt. The return interrupt specifies the data processing thread which is active on the second operating system such that an appropriate task switch or resumption may be made on the first operating system. The technique is particularly well suited to systems utilising a secure operating system and a non-secure operating system executing on the same hardware.
