Embodiments of the present invention provide an improved transformation method whereby the peripheral pulse waveform is filtered to separate different phases which make up the waveform. The separate phases are transformed before being re-combined to provide an estimated intra-arterial transfer function. For example, in one embodiment the peripheral pulse waveform is filtered by a first high pass filter, and a copy of the peripheral pulse waveform filtered by a second high pass filter, having a different cut-off frequency. The two filtered waveforms may then be further processed, for example by being added back to original wave-form, and are then multiplexed together in a time division manner to provide a final waveform. For example, the part of the first filtered waveform corresponding to the systolic phase may be combined with the part of the second filtered waveform corresponding to the diastolic phase to produce the final waveform, and the respective filter cut-off frequencies may be chosen to extract characteristics of the respective phases of the heart.

The invention provides a method for easy prefabrication of a self aligning three dimensional roof support and roof structure, such as a dormer or porch roof, which is fully constructed of sheet goods with tab and slot interconnecting components. The roof support structure is constructed of a parallel aligned space series of substantially rigid sheet truss members and a parallel aligned space series of substantially rigid purlin members running perpendicular to the truss members and interlocked with the truss members with opposing interlocking slots to form a self- aligning three dimensional support structure whereby the flush upper sheet ends provide support for roof sheathing. The roof sheathing and additional side fascia members are fit to the substructure with inter-engaging tabs and slots.

A toilet overflow prevention device including an overflow valve assembly, a control valve and a water level sensor. The overflow valve assembly is configured to selectively permit a flow of water through the valve assembly from the tank to the bowl of an associated toilet. The water level sensor is configured to provide a control signal in response to detecting an above-normal water level within the bowl of the toilet. The control valve is configured to actuate the overflow valve assembly in response to a control signal from the water level sensor. Preferably, the overflow valve assembly is separate from the primary flush valve of the toilet and is located between the primary flush valve and the bowl of the toilet.

An acoustic dampener (100) comprising a base member (101) having a first surface (102) and a second surface (103), the first surface (102) and the second surface (103) are spaced apart from each other defining a thickness (104) therebetween. The acoustic dampener (100) further comprising a pair of side arms (105), each having a first end (109) and a second end (110). Each side arm (105) is attached to the base member (101) at its first end (109) at a predetermined angle. The side arm (105) extends from the base member (101) to form a channel formation (119) to receive a batten. A flange (106) extends substantially orthogonally from the second end (110) of each side arm (105) for retaining a batten within the channel formation (119).

One aspect of the invention uses a sealed housing and using a battery of sufficient voltage/power to continue the a light source projected for at least eight hours into the display.
