Abstract: A sensor assembly and sensing method is provided for proximity detection for assessing an attachment state of a sensing probe with respect to a subject. A probe is coupled to an electronic probe controller. The probe includes a proximity sensor having a passive energy storing circuit element, and a biological sensor receptacle configured to receive a biological sensor for sensing a biological characteristic of an object. The electronic probe controller excites a circuit network incorporating the proximity sensor with an excitation signal and determines a characteristic of the circuit network that is excited by the excitation signal. The electronic probe controller further generates a proximity indication indicating whether the probe is attached to the object based on the characteristic of the circuit network.

Abstract: Disclosed is a putter head and a putter having the putter head comprising a putter head body having a putter shaft connector and least one horizontal bore extending therethrough and a locatable adjacent to the putter head body. The impact adjustment body has at least one bore alignable with the bore in the putter head body. The putter head further comprises a putter face plate locatable adjacent to the impact adjustment body such that the impact adjustment body is disposed between the putter face plate and the putter head body and at least one weighted fastener sized to extend through the bores in the putter head body and the impact adjustment body so as to secure the putter face plate to the putter head body. Also disclosed is a kit for constructing an adjustable putter head including a plurality of interchangeable impact adjustment bodies and weighted fasteners.
