Abstract: As may be implemented with one or more embodiments herein, aspects of the disclosure are directed to an apparatus having one or more sensor circuits and a wound-characterization circuit that generates data that characterizes a condition of the wound based on physiological characteristics detected by the sensors. A wireless communication circuit wirelessly transmits the characterization data, which can be carried out while the wound is covered. In various implementations, an integration circuit (e.g., connecting circuitry and/or a chip) includes the wound-characterization circuit and the sensor circuit, and further couples to a wound dressing for sensing the different physiological characteristics of the wound while the wound dressing covers a portion of the wound from which the different physiological characteristics are sensed.

Abstract: To test the processing of a data frame processing unit (FPU) which, in a normal working mode, processes input data frames applied to a data frame input (FI) thereof, the data frame processing unit (FPU) is brought in a test mode. Therefore, an active test signal is applied to a test mode control input (TCI) of this data frame processing unit (FPU). When brought in the test mode, the frame counters of the data frame processing unit (FPU) have lower limits and test data frames with smaller dimensions than the input data frames applied to the data frame input (FI).
