Abstract: An expandable partitioning device includes a pair of slide bars. Each slide bar includes a pair of first cooperating surfaces for slideably connecting the other slide bar. The first slide bar has a plurality of recesses along its length. The second slide bar has a rotatable toggle switch with at least one locking member. When the toggle switch is engaged (rotated) the locking member(s) rotate into the recesses of the first slide bar, locking the relative positions of the two slide bars.

Abstract: In an embodiment, the present invention provides a computer system for use by caregivers in the prevention and treatment of acute otitis media (AOM) with the use of the Galbreath technique in children from shortly after birth to about six years of age. The computer system assists caregivers in the monitoring of children who may be at risk for AOM or who may be experiencing an active episode of AOM. The system may make automated suggestions in real time of treatment options available to a caregiver at home. The computer system may include a diary component, and may include a Virtual Coach component providing reminders in real time and educational materials in the use of the Galbreath Technique and other medical interventions in the prevention and treatment of AOM.

Abstract: In one embodiment a method for suppressing narrowband interference in an RF signal is provided. The method includes providing a block of baseband digital samples of the RF signal and computing n-1 stages of an n stage fast Fourier transform (FFT) on the block of the baseband digital samples to produce a first block of intermediate data points. A final threshold is computed based on values of the intermediate data points. A final stage of the n stage FFT is computed from the first block of intermediate data points to produce a block of output data points, and the output data points that have an energy above the final threshold are attenuated.
