1. An arrow nock for mounting on an end of an arrow shaft, comprising:
- a housing having a longitudinal axisand, the housing having a set of first and second ends leading end and a distal end;
an impeller disposed along the longitudinal axis having a first end disposed within the housing and a second end disposed outside of and projects from the housing, wherein the impeller and the housing are moveable relative to each other;
wherein movement of the housing relative to the impeller occurs rotationally and freely about the longitudinal axis; and
,a retainer depending edge to capture at least one of the ends of the impeller being a first or end and a second end of the impeller within the housing, the housing having a distal end with the depending edge defining an aperture to entrap the impeller.

Abstract
An arrow nock having a telescoping impeller and housing with resilient means for enhancing the acceleration of launch. In various embodiments, effective together or independently, the housing and impeller are configured and coupled to: create arrow rotation during launch; grip the bowstring during notching and release it during launch; and generate tracking signals.

18. An arrow nock for mounting on an end of an arrow shaft, comprising:
-
a housing having a longitudinal axisand, the housing having a set of first and second ends leading end and a distal end; an impeller disposed along the longitudinal axis having a, first end disposed within the housing and a second end disposed outside of projects from the housing, wherein the impeller and the housing are moveable relative to each other; a distal end of the housing configured to capture at least one of the ends of the impeller being a first end of the impeller and a second end of the impeller within the housing, the housing having a distal end defining an aperture to entrap the impeller; a resilient member means positioned to resist movement between the housing and the impeller; a locking member to hold cocking section preventing movement of the impeller in a fixed position relative to the housing; and
,a release member to release the locking member to permita release from a drawn bowstring which is engaged in the nock causing the release of the housing and the impeller permitting movement of the impeller relative to the housing. - View Dependent Claims (19, 20)

21. An arrow nock for mounting on an end of an arrow shaft, comprising:
-
a housing having longitudinal axis and having a set of first and second ends leading end and a distal end; an impeller disposed along the longitudinal axis having first end disposed within the housing and a second end disposed outside of the housing projects from the housing, wherein the impeller and the housing are moveable relative to each other; a means bowstring notch for engagement by a bowstring; a retainer to capture at least one of the ends of the impeller being a first end of the impeller and a second end of the impeller within the housing, the housing having a distal end defining an aperture to entrap the impeller; a releasable gripper movable within the nock to selectively retain hold the arrow on the bowstring, limiting disengagement of the bowstring prior to launch, and release the bowstring when the housing and impeller are axially displaced, providing clear passage for the bowstring upon launch of the arrow. - View Dependent Claims (22, 23, 24, 25, 26)

27. An arrow nock for mounting on an end of an arrow shaft, comprising:
-
a housing having a longitudinal axis and having set of first and second ends a leading end and a distal end; an impeller disposed alone along the longitudinal axis having first a leading end disposed within the housing and a second end disposed outside of the housing, projects from the housing wherein the impeller and the housing are moveable in axially opposite directions relative to each other; an energy source; an electrical component operative when connected to, the energy source; and
,a connector conductor mounted on between the housing and the impeller with the housing having a conducting surface which is used to connect the energy source and the electrical component when the housing is in a predetermined position relative to the impeller. - View Dependent Claims (28, 29)
