A system for preventing overflow of a toilet includes a sensor, a processor and an actuator. The sensor senses a parameter caused by fluid dynamics within the toilet during a flush cycle. The parameter may involve vibration, sound, pressure, fluid flow rate or other detectible characteristics of the toilet. The processor uses information regarding the parameter that is gathered by the sensor to evaluate the condition of the flush cycle to determine if an impeded flush condition exists. In the event of an impeded flush condition, the processor directs the actuator to close a valve, which may be the toilet flapper valve in some embodiments. Also disclosed are methods for preventing toilet overflow, detecting an impeded flush condition and calibrating the system.

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.

A system for preventing overflow of a toilet includes a capacitance sensor arrangement as in combination with certain features (e.g., flap valve disablement). The system can detect an overflow flush condition of a toilet by sensing the value of a parameter of one or more normal flush cycles of the toilet and establishing a normal range for the value of the parameter using the sensed value. The system can also store the normal range in a memory for comparison to a value of the parameter during subsequent flush cycles. The system can perform sensing over a predetermined timeframe. The system can include the time frame being sufficient to include the entire push cycle of the toilet.

Disclosed in one aspect is a method for performing a complete blood count (CBC) on a sample of whole blood by metering a predetermined amount of the whole blood and mixing it with a predetermined amount of diluent and stain and transferring a portion thereof to an imaging chamber of fixed dimensions and utilizing an automated microscope with digital camera and cell counting and recognition software to count every white blood cell and red blood corpuscle and platelet in the sample diluent / stain mixture to determine the number of red cells, white cells, and platelets per unit volume, and analyzing the white cells with cell recognition software to classify them.

A suspended ceiling comprising a grid formed of intersecting grid runners and snap-up panels supported on the grid runners, the grid runners dividing a ceiling area into standard modules, the pans being formed of sheet material and each having its sides sized to cover the module size while leaving a space at visible faces thereof between adjacent panels when in an installed position on the grid, at least one adjacent pair of panels being displaceable from their installed positions, the gap between a pair of displaceable panels being closed by a removable runner or the displaceable panels so that when the displaceable panels are displaced from their installed position and any removable runner is removed, an access opening of twice the standard module is made available for accessing the area above the ceiling while adjacent panels at longitudinal ends of the gap between the displaceable panels can remain in respective installed positions.

The present invention is directed to the processing of a biological sample into its constituent components for use in ART and includes introducing a sample into a first volume disposed adjacent a second volume comprising buffer solution; wherein the first and second volumes are adapted for fluid communication therebetween; selectively separating the first volume from the second volume with a movable closure member disposed therebetween; wherein the step of selectively separating the first volume from the second volume comprises moving the closure member so that a fluid communication aperture is formed by one or a combination of the closure member or the closure member in combination with the first and second volumes to allow fluid communication between the first volume and the second volume such that motile cells migrate from the sample in the first volume to the buffer solution in the second volume.

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.
