Abstract: An archery sight having a pin gap adjustment mechanism to adjust a pin gap between a first pin and a second pin to compensate for arrow drop at different ranges. The pin gap adjustment mechanism may include a cam and a follower pin rigidly connected to the second pin. Input from an actuator may cause the cam to rotate and thereby increase or decrease the pin gap between the first pin and the second pin. The cam may comprise an outer surface with a continuously variable irregular surface to provide multiple adjustments for arrows with different trajectories.

Abstract: A retractor system used in preparation for an oblique lateral interbody fusion surgical procedure includes a first retractor blade having a first proximal portion and a first distal end; a second retractor blade having a second proximal portion and a second distal end; and a connecting device that is configured to connect the first retractor blade to the second retractor blade. The first distal end of the first retractor blade is configured to engage a posterior portion of the vertebra and the second distal end of the second retractor blade is configured to engage an anterior portion of the vertebra. The length of the first retractor blade is less than approximately 96 percent of the length of the second retractor blade, and the first distal end of the first retractor blade extends at a non-zero angle from the first proximal portion of the first retractor blade.

Abstract: A dynamic disc assembly has a superior end plate, an inferior end plate, and a core. The core has surfaces of an annular Fresnel shape and a linear Fresnel-like shape combined to control the dynamic range of motion (ROM) movement arranged to match anatomical ROM. The core is interposed between and held against interior surfaces of the superior end plate and the inferior end plate. The assembly further has a pair of coupling cords, one coupling cord at each lateral end of the superior and inferior end plates wherein each lateral end of each end plate has one or more cord connections attached and affixed to the coupling cord to form and retain the dynamic disc assembly.

Abstract: Retractor blades for a retractor system are disclosed. The blades are designed for use in preparing an area of the body for a surgical procedure. The retractor blades are configured with different lengths and with different blade tip geometries to facilitate engagement with vertebrae for the oblique lateral interbody fusion surgical approach.

Abstract: A retractor system for use in preparing an area of the body for a surgical procedure is disclosed. The retractor system includes retractor blades that can be independently inserted and positioned within the body. The system also includes articulating arms that can be used to secure the retractor blades to one another and to rigidly fix the retractor blades in place relative to an operating table or other fixed structure.

Abstract: A system and method of positioning a spinal implant into an intervertebral space comprises the steps of: cutting an incision through the skin toward an intervertebral space between a L5 and S1 vertebra; inserting an uncoupled first, second and third retractor blade into the incision to pre-position the retractor blades prior to retraction; coupling the pre-positioned first retractor blade to a connector arm to connect the first retractor blade to a table arm; attaching a blade to blade connector and mini flex arm to couple the second blade to either the first blade or third blade; and wherein the three uncoupled blades, once pre-positioned and then coupled, the blades are retracted to open the incision and expose the vertebral bodies.

Abstract: Systems and methods for training and using machine learning models to classify vehicles from highway radar systems are provided. The training systems may use auxiliary radar processing to separate events by lane, length, and/or speed, and then use separate event data groups pooled from similar or proximate lanes, lengths, and/or speeds to train multiple models. At estimation time, incoming events may be grouped using similar groupings as those used during training to select which model to use. An incoming event may be applied to the neural network operations of the selected model to generate an estimate. Generating an estimate may involve successive applications of multiple linear convolutions and other steps along varying or alternating dimensions of the in-process data.

Abstract: A backpack or other personal article having a changeable ornamental feature. The article includes an exterior surface with loop material affixed to a substantial portion of the exterior surface area of the pack or bag. The user may detachably secure patches or other objects to the surface of the backpack or personal article with hook and loop fastener material, providing a mechanism by which the user may accessorize and personalize their personal articles.

Abstract: An improved mitt for cold weather use is configured to provide a variety of modes of wear. The mitt is convertible between a fully closed position for covering the hand and fingers and open positions for exposure of the thumb and/or finger(s) or the entire hand. An internal pocket within the mitt permits continuous or intermittent warming of all or some of the fingers when the mitt is in either a generally open position or closed position. Insertion and removal of fingers and thumb relative the internal pocket is easily accomplished without use of the other hand. A thumb hole and/or finger hole for thumb/finger exposure is formed with an overlapping two-layer seal of stretchable material to prevent heat loss while ensuring easy thumb/finger insertion and removal. In one embodiment, stretchable fillets connect the terminal ends of the palm side and back side of the mitt to provide a snug fit about the wrist.

Abstract: A versatile upper body multi-mode garment is configured to provide a variety of modes of wear with respect to hand coverings and head covering. A coat, jacket, shirt or vest has an integral hood which covers the wearer's head. Within the hood is an integral face shield which may be swung behind the wearer's head or neck when not covering the face, enabling protection of various portions of the face. The hood may be tightened to expose a variable extent of the head or face. Versatile multi-mode mitten portions attached to the garment or mittens provided separately enhance a variety of modes of wear which are achieved without removing the mittens or any portion thereof. The wearing modes include full exposure of a hand, exposure of the thumb and the four fingers, exposure of the four finger tips, full hand coverage, and full hand coverage by an integral glove.
