  • Publication number: 20130003043
    Abstract: A measuring system for determining blood glucose includes a photometric measuring unit with a light source and a detector, and an analytical test element, to which a body fluid sample can be applied, and which can be placed in a beam path between the light source and the detector for optical detection of an analyte. For an improved multi-wavelength measurement, it is proposed that the light source includes a first emitter that can be actuated in a first wavelength range to emit pulsating alternating light and a second emitter that can be excited in a second wavelength range to emit fluorescent light.

  • Publication number: 20120229810
    Abstract: There is disclosed a method for controlling a photometric measuring unit of a measuring device for a bodily fluid sample, wherein a test field partially wetted by a bodily fluid sample is illuminated and light from a measuring area that covers a portion of the test field of the measuring unit is fed to a detector of the measuring unit, and the measuring area is displaced relative to the test field toward a partial surface wetted by the fluid sample and past the partial surface. The intensity of a detector signal is detected during the displacement, an extreme value in the course of the detector signal is determined, the measuring area is brought back to the position in which an extreme detector signal was previously measured, and the position of the measuring area in which the detector signal is extreme is used for a photometric determination of concentration.

  • Patent number: 7951331
    Abstract: The invention relates to embodiments of an analysis system and to a method for analyzing a sample on an analytical test element, with the analysis system comprising a test element receptacle for receiving and positioning a test element in an analysis position. In an exemplary embodiment, the test element receptacle contains a guide part and a lock part, the guide part having means for guiding a test element into and out of the analysis position, the lock part comprising a frame and a bolt element, which frame and bolt element are connected to one another by a hinge. The bolt element can be pivoted about the hinge between a first position and a second position with respect to the frame. The bolt element comprises a latching lug for engaging in a recess in test element when the bolt element is in the first position and when the test element is positioned in the analysis position.

  • Publication number: 20080087819
    Abstract: The invention relates to a method for analyzing a fluid sample, such as a body fluid sample in which, after loading a test element with a sample of a fluid, the fluid sample passes into a detection area of the test element and spreads out in the detection area, and in which a filling extent which characterizes the spread of the fluid sample in the detection area is determined using a photometric measurement of the fluid sample in the detection area, wherein the photometric measurement is carried out by means of a first light which is irradiated onto the fluid sample in the detection area, said first light having a first wavelength for which, when at least one chemical parameter of the fluid is varied, the fluid has an essentially constant optical behaviour with respect to at least one spectroscopic parameter selected from a group of spectroscopic measurement parameters consisting of absorption, transmission, remission and fluorescence, and wherein the at least one chemical parameter of the fluid comprises at

  • Patent number: 5670941
    Abstract: A terminal for contactless communication with portable objects comprises a wave pickup device responsive to the magnetic component of an electromagnetic field, and a receiver which cooperates with the wave pickup device to receive and amplify signals picked up thereby. The wave pickup device comprises at least two distinct and adjacently disposed wave pickup elements spaced apart by a predetermined gap, and a discriminator for deriving a discrimination signal from the signals picked up by each of the wave pickup elements during a given period. The discrimination signal indicates which one of the wave pickup elements has received a signal of greater amplitude.

  • Patent number: 5540069
    Abstract: A locking device including both a mechanical lock operable with a key and an electrical lock, operable from the same key. The device includes an electrical circuit for operating the electrical lock. The electrical circuit has a microprocessor and memory which stores the identity of keys authorized to open both the mechanical lock and electrical lock. A master key is provided which includes at one end a connector which engages a connector within the mechanical lock when inserted. Information is read from the master key, identifying a set of keys which are authorized to open the lock. Whenever a key from the set of authorized keys is inserted in the lock, an identification number is read through a contact member from a memory associated with the key, and an electrical signal is generated by the electric circuit of the lock to operate the electrical lock.
