There is described a device for the non-invasive measurement of one or more analytes in blood in a patient’s body part which comprises a light transmitter comprising a plurality of transmitting fibres positioned to transmit light to the body part and a light detector comprising a plurality of light detector fibres position to detect light transmitted through or reflected from the body part. The link or string includes at least one contact configured to electrically connect the memory cells to at least one control line, and the number of contacts in the string or link is the same as or less than the number of memory cells in the string or link. Therefore, by allowing different types of DAB receivers to uniformly process video services, it is possible to achieve high efficiency in video service processing and controlling. The data shift register is further adapted to provide configuration data from the spare configuration memory cell to the identified configuration memory cell. The method of producing the injector includes connecting the valve body to the injector body, and fixing the valve body in a given position along the axis with respect to the injector body by means of a driving operation to interference fit the valve body inside the hole in the injector body. The resulting system provides a hidden connection between the water dam and the fascia, is inexpensive, and can be quickly and easily assembled and disassembled without any tools, while also providing superior wind and water resistance and improving the appearance of the roof edge.
