  • Patent number: 11612356
    Abstract: An on-diaper body fluid screening device (100), comprising a stack of the following sheets: a surface sheet (110) permeable to body fluid, a collection sheet (120) impervious to body fluid, a testing sheet (130), which is body fluid absorbent and provided with colorimetric assay reaction pads (131), and which is provided with a body fluid barrier network (132) forming body fluid channels (134) between an inlet section (135) and the colorimetric assay reaction pads (131), a protection sheet (140) impervious to body fluid, and a transparent readout sheet (150), through which the assay reaction pads (131) are visible. The protection sheet (140) comprises pad receiving openings (142). The collection sheet (120) comprises an inlet hole (125) which is arranged over the inlet section (135). A swelling component (702) is arranged in association with the inlet hole (125) and an inlet hole closing member (601).

  • Patent number: 7123153
    Abstract: A system and method of tracking individuals divided into flocks by means of radio communication and positioning systems is disclosed. A flock leader is provided with a first electronic device (1) comprising a first transceiver (2) operating in a public radio communication network, e.g. GSM or GPRS, a position tracker (3), e.g. a GPS-receiver, and a second transceiver (4) operating in a short distance radio communication system, e.g. Bluetooth®. Each of the remaining individuals in the flock is provided with a second electronic device (6) comprising at least a third transceiver (7) also operating in the short distance radio communication system. The second electronic device (6) periodically transmits data identifying the associated individual to the first electronic device (1), so that the flock leader knows that the individual is localized in the flock (i.e. within the coverage area of the short distance radio communication system) as long as it receives the data.
