Abstract: Devices and methods are provided for continuous measurement of an analyte concentration. The device can include a sensor having a plurality of sensor elements, each having at least one characteristic that is different from other sensor(s) of the device. In some embodiments, the plurality of sensor elements are each tuned to measure a different range of analyte concentration, thereby providing the device with the capability of achieving a substantially consistent level of measurement accuracy across a physiologically relevant range. In other embodiments, the device includes a plurality of sensor elements each tuned to measure during different time periods after insertion or implantation, thereby providing the sensor with the capability to continuously and accurately measure analyte concentrations across a wide range of time periods.

Abstract: The invention comprises an assembleable mantelpiece, which includes a mantel, a pair of side members, and means for positioning and securing the mantel and pair of side members relative to each other and relative to a fireplace, so as to enable the mantelpiece to be manufactured, shipped and stored disassembled, and assembled and installed relative to a fireplace conveniently and efficiently, without subjecting the mantelpiece to possible damage resulting previously from installation thereof, and without requiring finishing necessary previously as a consequence of such installation thereof.
