    摘要: A badge (26) for locating and tracking a hospital asset (11) includes a motion sensor (30) carried by the asset (11) that generates a motion signal when the asset (11) is in motion. The motion signal varies with changes in the speed of the moving asset (11). The badge (26) further includes a transmitter (34) coupled to the motion sensor (30) that transmits an information signal at a transmission rate that varies as a function of the variable motion signal. The badge (26) may be configured to provide fault tolerant reception by transmitting information in packets including periodic error codes.
