摘要:
Apparatuses and methods providing data such as, for example, calibration and reagent information (30) over a network (6) to a measurement apparatus (4) which makes use of a consumable reagent (18) in a measuring process are disclosed. The present invention permits a measurement apparatus (4) to download the necessary code assignment (24) and calibration data (32) of the consumable reagent (18) by means of an electronic communication protocol from a host (33). The host (33) can be a software application running on a host computer (34), another measurement apparatus (50, 58) with or without a code-key slot used to read a memory device providing the above mentioned information (30), a dedicated connectivity device, such as a docking station (44), a portable memory reader (48), a remote computer (54), and combinations thereof.

The invention relates to a sampling device for liquid samples, in which the sample is transported in a capillary-active channel from a sampling point to an identification point and the capillary-active channel is substantially configured from a support, a covering and an intermediate layer lying between the support and the covering. The support extends over the covering in the vicinity of the sampling point and the intermediate layer is recessed away from the sampling point in the vicinity of the latter. The device permits both a top dosing of the sample onto the exposed area of the support in the vicinity of the sampling point and a side dosing of said sample.

The invention relates to an analysis system for analysing an analyte contained in a sample of body fluid. Said system comprises a test element (3) that respectively comprises a housing (15) and an analysis function channel (16) that is surrounded by the housing (15), and an evaluation device (2) comprising a measuring station (6) for measuring a measurement variable characterising the analysis result in the measurement zone (19) of the test element (3), and comprising a preferably rotatable maintaining element for maintaining a test element (3). Said test element (3) comprises an air flow channel (25) having two wider sections (26a, b) and a narrow section (27) that is arranged between said wider sections (26a, b). Said wider sections (26a, b) have a cross-sectional surface that increases compared to the narrow section (27) in the direction away from said narrow section, and a connection channel (24) is arranged in such a manner between the narrow section (27) and the analysis function channel (16) that an air exchange connection is formed, the air flow channel (25) being arranged in such a manner that low pressure produced by means of an air flow flowing through the air flow channel (25) acts upon the analysis function channel (16).

The invention describes systems and methods for optically imaging objects and in particular optical patterns or codes onto a detection device by means of a pinhole aperture. According to the invention these systems have optical attenuation elements between the illumination devices and the object which substantially compensate the system-inherent imaging defects caused by the pinhole aperture and in particular the system-inherent peripheral decrease in brightness of an image of the object formed by a pinhole aperture on the detection device. According to the invention the optical attenuation elements change the illumination intensity of the object in such a manner that the central areas of the object are illuminated at a lower light intensity than its peripheral areas. As a result of the subsequent imaging of the object by means of a pinhole aperture, the central areas of the object are imaged onto the detection device at a higher light intensity than the peripheral areas of the object. The superimposition of the two effects enables the imaging system according to the invention to achieve a substantially uniform system-inherent brightness distribution on the detection device.
摘要:
An electronic device enclosure having an integrated in-mold foil, which prevents fluid ingress around an included display of the electronic device, is disclosed. A portion of the in-mold foil is adapted to the specific contour and profile of the display, thereby allowing a user to use a touch screen interface of the display with no shortcomings. In addition, the in-mold foil protects the display from direct chemical attack, and may provide a liquid-tight seal between a button of the electronic device and the enclosure.

The invention provides for a cartridge (100, 200, 300, 500, 500', 500", 602, 602', 602", 1100, 1100', 1200, 1200', 1300, 1300', 1400, 1400', 1600, 1900, 1900', 1900", 2000, 2100, 2200, 2300, 2500, 2600) for dispensing a fluid (123). The cartridge comprises: a rigid portion (102), a flexible bladder (104), and an outlet (108). The outlet is attached to the rigid portion. The rigid portion comprises an inner cavity (116). The outlet is connected to the inner cavity. The rigid portion comprises an opening (114). The opening is connected to the inner cavity. The flexible bladder seals the opening to form a fluid chamber (122) from the inner cavity.
