Abstract: A delivery guidewire (100), comprising: a core wire (110) comprising a first segment (111), a second segment (112) and a third segment (113), which are arranged in sequence and have diameters decreasing in the direction from a distal end to a proximal end of the delivery guidewire (100); a metal ring (130) at least partially disposed at a proximal end of the first segment (111); and a spring (120) at least partially disposed over the outer side of the second segment (112). A distal end of the spring (120) abuts against a proximal end of the metal ring (130), and a distal section of the spring (120) has a diameter smaller than a diameter of a proximal section thereof. The diameter of the distal section of the spring (120) that is smaller than the diameter of the proximal section of the spring (120) results in a smaller clearance between the distal section of the spring (120) and the core wire (110), which enables greater concentricity of the distal section of the spring (120) with the core wire (110).

Abstract: A baseband process operating on a receiver in a communication system, such as an 802.15.4 communication system, is provided. The baseband process has a set of predefined reference signals, with each reference signal associated with a possible characteristic in the baseband signal. The baseband process receives a degraded baseband signal, and preprocesses the baseband signal to reduce or remove the effects of the degradation. The preprocessed baseband signal is correlated with reference signals from the set of predefined reference signals, and the reference signal with the best correlation is identified. By identifying the best correlating reference signal, the baseband process is able to identify a characteristic of the baseband signal. In one example of the baseband process, the baseband signal is preprocessed by auto-correlating the degraded baseband signal with a delayed version of the degraded baseband signal.
