Abstract: A portable analytical device includes a housing, a measuring facility and a processor in the housing, and an electrical connector having one end electrically connected to the processor and an opposite end operatively connectable to an external electronic device. The measuring facility is configured to analyze a change in a test element resulting from receipt thereon of a liquid sample of a body fluid and to generate measuring values resulting from the analysis. A memory has instructions stored therein executable by the processor to process the measuring values to generate analytical measuring data based thereon and to output the generated analytical measuring data onto the electrical connector. The analytical device does not include an intrinsic user interface for displaying the generated analytical measuring data. Display of the generated analytical measuring data is implemented exclusively by the external electronic device having received the generated analytical measuring data via the electrical connector.

Abstract: A shutter assembly includes a first shutter blade having a first toothed arm extending therefrom and a first light transmitting aperture therein, and a second shutter blade positioned adjacent and parallel to the first shutter blade. The second shutter blade has a second toothed arm extending therefrom and a second light transmitting aperture therein. The first and second shutter blades are supported to allow parallel linear motion. A motor gear is disposed between, and meshed with, the first and second toothed arms such that rotation of the gear causes the first and second shutter blades to move linearly in opposite directions between an open position in which the first and second light transmitting apertures are in an overlapping relationship with respect to one another, and a closed position in which the first and second light transmitting apertures are in a non-overlapping relationship with respect to one another.

Abstract: A handheld-sized, single-hand-holdable, single-hand-operable battery-powered gas leak detector that draws in a sample of ambient air for detecting the presence of a gas by sensing changes in infrared (IR) energy between an IR emitter and an IR sensor when the gas is in the space between the IR emitter and the IR sensor. An algorithm is used that triggers detection of a gas when the change in IR energy between the IR emitter and the IR sensor is more rapid than the thermal drift of the IR sensor, and the detector design allows for IR energy within a wide range of approximately 0.4 micrometers to approximately 20 micrometers to pass into the air being sampled.
