The present invention relates to a data processing apparatus and method for compiling application code. The data processing apparatus comprises a processor, and a compiler for compiling application code to generate instructions for execution by the processor. Furthermore, a non-invasive trace unit is coupled to the processor for generating, from input signals received from the processor, trace signals indicative of the instructions being executed by the processor. The compiler is then arranged to control the compilation of the application code dependent on the trace signals. The non-invasive nature of the trace unit enables it to generate trace signals that can be used to produce profiling information for use by the compiler without altering the behaviour of the code being executed by the processor, and accordingly provides a significantly improved technique for obtaining profiling information for use in feedback driven optimisation compilation techniques.

Therapeutic devices and methods according to embodiments of the invention alleviate e.g. urinary incontinence in female and male patients. Suction or vacuum, for example, is applied to the genital region, clitoris or clitoral region, the external urethral orifice, and / or other designated areas, e.g. physically stimulating the sacral / pudendal nerves and / or nerve roots and alleviating incontinence. Such embodiments also can encourage or cause clitoral engorgement, or otherwise promote blood flow in the genital region. Vacuum or suction applied to e.g. the clitoris creates a negative pressure in the clitoris that is lower than the systolic blood pressure, tending to promote engorgement of the clitoris with blood. Aspects of the invention are applicable not only to treatment of urinary and fecal incontinence, but also to the treatment of female sexual dysfunction. Aspects of the invention are also applicable to treatment of male incontinence and male erectile dysfunction.

The present invention provides a method and device for characterizing a physiological parameter. The method, in one application, uses one or more non-invasive sensors to collect patient data, and may also collect data on environmental conditions. At least some of the patient data has a direct relationship with the physiological parameter, that is, a change in the physiological parameter is reflected in the data set, although the magnitude of the physiological parameter may masked by noise, interference, or other environmental or patient influences. The direct patient data preferably has a generally linear relationship with the physiological parameter, and if not, the patient data is linearized according to an algorithm, table, or other adjustment process. These linearizing processes may be predefined, and may adaptively learn or adjust. A blind signal source process is applied to the linearized data to generate separated signals, and the signal associated with the physiological parameter is identified. The identified signal is scaled or further processed, and the characterization result is presented. Although the method and device are described for use with a human, they may be advantageously used on animals.
