For enabling an improved reconstruction of a high frequency band of an audio signal in a split-band coding approach, a value representative of a background noise level in an audio signal that is to be encoded is determined. Further, a gain value for the higher frequency band is determined. Further, a correction factor for the determined gain value is determined based on the determined value representative of the background noise level. The correction factor may be used at an encoding end for correcting the gain value before a corresponding codebook index is provided to a decoding end. Alternatively, the correction factor may be provided together with a codebook index for the gain value to a decoding end, and the decoding end may use the correction factor to correct the gain value if appropriate.

The present invention relates to systems and methods for height adjusting patient support platforms, such as, for example, of a bed (e.g., the mattress support platform of a standard hospital bed with side rails), gurney, couch, chair, or recliner, to which a patient may be confined. The systems and methods are designed to lower the height of a patient support platform at least closer (and essentially all the way) to floor level in a relatively quick and controlled manner to reduce fall distances. Lowering the height of a patient support platform corresponding reduces the likelihood and significance of patient injuries resulting from falls when a patient attempts to exit the patient support platform.
