Abstract: An aiming device is provided including an illumination device and an optical element wherein the illumination device projects a primary dot and at least one secondary alignment dot distal from the primary dot to aid a user in obtaining a view of the primary dot when the aiming device is in an aligned mode, the primary dot is visible within a field of view of the user, but the secondary alignment dot is not visible. When the aiming device is in a misaligned mode, the secondary alignment dot is visible to the user, but the primary dot is not. The secondary alignment dot provides instruction to the user to realign the aiming device relative to the field of view of the user so that the aiming device transitions to the aligned mode. A related method of operation is provided.

Abstract: An archery bow is provided including opposing limbs and a riser. The riser can include a riser handle and one or more primary riser elongated elements extending away from the handle to respective limbs. The primary riser elongated elements can be straight, elongated round or other shaped tubes, rods or bars constructed optionally from a composite or other material. Vents can be included in ports of the riser to facilitate escape of air when riser elongated elements are installed in those ports. The riser can include one or more connector lugs disposed between tube portions to facilitate attachment of accessories to the elongated elements. The elongated elements can be bonded, adhered or otherwise fixed to the riser handle, struts, lugs and/or limb pockets, which can be constructed from a metal such as aluminum, titanium or an alloy, and which can handle significant moments and forces transferred via the elongated elements.

Abstract: An archery bow assembly is provided including an open sided spacer which is mountable to an axle on an archery bow and removable therefrom without removing the axle entirely or partially from a limb of the archery bow.

Abstract: A grip for a weapon is provided and can include a user engagement area including a first surface on the weapon, a first layer including an aerogel, the first layer disposed adjacent the first surface, and a first engagement member disposed over the first layer in the user engagement area. The first engagement member includes an exterior surface that engages an appendage of a user when the user holds the weapon. The first layer including the aerogel insulates the first engagement member so that thermal energy transfer between the user and the weapon is impaired. The weapon can be an archery bow, a firearm or any other weapon including a grip or portion that is engaged by an appendage of a user.

Abstract: An aiming device is provided including a body, an optical element joined with the body that has selectively displayed thereon a dot visible to a user along a first line of viewing, and a power indicator distal from the optical element, where the power indicator emits illumination along a second line of viewing, offset from the first line of viewing. The power indicator can alert the user via the illumination that the dot is or is not displayed on the optical element, without the user needing to directly view the dot along the first line of viewing. The illumination emitted by the power indicator can be of a first visible wavelength range, e.g., blue, and the dot can illuminate in a second visible wavelength range different from the first visible wavelength range, e.g., green or red, so the likelihood of confusing the power indicator with the dot can be reduced.

Abstract: An illuminable device configured to be worn by a mammal and provide visibility to the mammal includes a thermoelectric module and a light source. The illuminable device is configured to be mounted onto a mammal by an article worn by the mammal such that the thermoelectric module is in thermal contact with the mammal's body. The thermoelectric module generates electricity from a thermal gradient, produced from a mammal's body heat that is transferred to the module. The electricity generated by the thermoelectric module powers the light source to illuminate the article worn by the mammal. Related methods are also provided.

Abstract: A mechanical broadhead, which has blades movable from a retracted mode to a deployed mode, is provided with ball and socket members that hold the blades in the retracted mode, and selectively release the blades to the deployed mode. The ball and socket members, which can be on the blades and/or on a retainer element, can be snapped together to provide an audible snap confirming locking of the blades in the retracted mode. The mechanical broadhead can include first and second ferrule portions removably joined with one another. The second ferrule portion can acquire a blocking mode to block a removal opening of a ferrule slot defined in the first ferrule portion so that blade cannot be removed from respective ferrule slots. The second ferrule portion can achieve a removal mode so that the blades can be removed from the slots.

Abstract: A range finder for determining a distance to a target object includes a thermoelectric module and a range finding unit. The range finding unit includes a light source for emitting light onto a target object, a light receiving unit configured to receive light reflected by the target object, a distance calculation unit for calculating the distance to the target object based on the reflected light, and a display unit for displaying the calculated distance to the target object. The thermoelectric module generates electricity from a thermal gradient, produced from a user's body heat that is transferred to the module. The electricity power generated by the thermoelectric module powers the components of the range finding unit. Related methods are also provided.

Abstract: An archery bow is provided including an axle assembly that compresses bearing and other components between limb portions to clamp those components against one another, with zero gaps therebetween, yet enable a cam to freely rotate relative to the axle. The bow can include bearings having an inner portion, and an outer portion non-rotatably joined with a cam. A fastener is operable in a compression mode to exert a compression force, such as an axial clamping force, against the bearing inner portion so it is non-rotatable relative to the axle, while the outer portion remains uncompressed and rotatable relative to the axle. The assembly can include a compression spacer clamped under the compression force between inner portions of bearings. These constructions can enhance the consistency of cam rotation and promote a smooth draw of the bow. Related methods are also provided.

Abstract: An aiming device including a thermoelectric module, a light source and a sight element. The thermoelectric module generates electricity from a thermal gradient, produced from a user's body heat that is transferred to the module. The electricity powers the light source. The light source illuminates a sight element of a projectile shooting device to enhance visibility of the sight element in a variety of ambient lighting conditions, optionally in low light conditions. The aiming device can be mounted to a projectile shooting device. With the aiming device, a user can selectively illuminate a sight element of a projectile shooting device, with the user's own body heat, to assist aiming the projectile shooting device during a shooting activity. The projectile shooting device can be any type of archery bow and/or firearm. Related methods are also provided.
