An instrument for analyzing test strips supporting chemistries which react with a medically significant component of a body fluid to indicate the concentration of the component in the body fluid. The instrument includes a pathway along which radiation is guided from a radiation source to a strip when the strip is inserted into the instrument and along which remission is guided from the strip to a radiation detector. A title provided on the instrument provides a first remission when no strip is inserted into the instrument. The tile is separated from the radiation source by the strip when the strip is inserted into the instrument. The first remission and the strip's remission, respectively, indicate the absence and the presence of the strip in the instrument. The strip also has a surface opposite the chemistry supporting surface characterized by a second strip remission different from the first strip remission. The instrument is capable of determining whether the strip has been inserted into the instrument correctly or backward.

A method and apparatus for measuring the heart rate of a patient. In one embodiment the apparatus includes a hollow bell mounted on a diaphragm. A transducer element is also positioned therein to receive sound transmitted through the diaphragm, convert the sounds into electrical impulses, and transmit the electrical impulses to a microprocessor. The electrical impulses have real-time wave patterns corresponding to the real-time wave patterns of the original sounds. The microprocessor performs mathematical operations on wave pattern data conveyed by the electrical impulses to determine a numerical value corresponding to the frequency of the wave patterns. This numerical value is sent to a digital output and displayed thereon.

A method and apparatus (10) for determining the remission of a chemistry (106) which reacts with a medically significant component of a body fluid. The remission of the chemistry (106) changes as it reacts. The method and apparatus (10) include irradiating the chemistry (106) with a radiation source (182), detecting remissions of radiation from the chemistry (106) with a radiation detector (300), providing a radiation pathway (164) between the source (182) and the chemistry (106), providing a remission pathway (164) between the chemistry (106) and the detector (300), and detecting the rate of change of remission of the chemistry (106) with respect to time. The irradiating, detecting and rate detecting steps and apparatus comprise initially irradiating the chemistry (106) at a first time rate and detecting remissions therefrom, comparing remission data from remission readings spaced apart by a first number of intervening remission readings, and determining when the difference between compared readings exceeds a first predetermined limit. The time rate of irradiation of the chemistry is changed once the difference between compared readings exceeds the first limit. Remission data from remission readings spaced apart by a second number of intervening remission readings are then compared.

A method of making an article is provided, including placing at least a portion of a panel in an injection molding die and overmolding at least one molded structure on a surface of the panel in the injection molding die, wherein the molded structure includes a foam composition. An article is also provided including a material-to-material connection between the surface of a panel and a molded structure. The panel includes first and second layers and a core disposed there between, wherein the core has a plurality of walls providing a series of connected cells. Some of the cell walls have openings providing fluid communication between a series of at least 3 cells, and the opening in a cell wall has an area that is at least 50 percent of the area of a side of that cell wall. Articles such as panels, walls, or other parts with curved surfaces can be formed according to certain exemplary embodiments. The articles are useful for absorbing sound in a designed frequency range.
