A hair ornament includes multiple light-emitting diodes (LEDs) which are manufactured as a single component so that their combined output can be focused on the end of a bundle of optic fibers. The fibers may be woven in the hair or wig of a wearer of the ornament. For a preferred embodiment of the invention, three LEDs, each of which emits a primary color (generally red, green or blue), are provided. Each LED is coupled to a flasher circuit having both variable frequency and variable duty cycle. At low frequencies (i.e., less than about 18-20 flashes per second), the flashes are seen as discrete colors. However, as the frequencies are increased, only a single color is visible. The color of that single color can be varied over the visible spectrum by varying the duty cycles of the three LEDs. One use of the preferred embodiment is to adjust the projected color to coordinate with clothing of the user.

A method for optimizing the stimulation of the dorsal column of the spinal cord is disclosed. The method includes providing a stimulating electrode array and a frame element. The frame element is configured to couple to the stimulating electrode array and guide the stimulating electrode array to a desired position proximate the dorsal column of the spinal cord of a subject.

Integrated surgical systems and methods for using same are provided that can receive scanned images and produce a three dimensional model from the images. Based at least in pan on the three dimensional model, a processor generates code defining an optimized tool path, which is sent to a surgical machining system that can machine the desired portion of the patient. In one exemplary aspect, the integrated system operates in a clearly defined and pre-programmed manner with no necessity for in-situ sensory or guidance feedback.

A device for repairing a bone disorder using a polyaxial screw. The device has a pivoted lever mounted rotatably to an extension of a bone screw and which extends essentially at right angles to the longitudinal direction of the extension to which it is mounted and is in contact with a stop on the other extension associated with the vertebral body to be repositioned. The extension that acts on the polyaxial bone screw comprises a longitudinal sleeve, a rod, preferably threaded, extending from within the sleeve and moveable within the sleeve, and a contact surface disposed on the end of the threaded rod which is configured to transmit a force against the bone screw to prevent polyaxial movement of the polyaxial bone screw for as long as the force is transmitted.

A bendable resilient fishing lure, that simulates the movement of live bait when a fisherman tugs on the fishing line, includes a resilient body molded to appear like a small animal such as an earthworm or small fish, the body having a fishing line securing device, at least one aperture in the body spaced apart from the securing device through which the fishing line is threaded, a resistance device slidably mounted on the fishing line between the fisherman and the body. When the fisherman tugs the fishing line, the resistance device applies a force to the body, causing it to bend. When the tugging stops, the resilient body returns to its original shape. The resistance device may be either a weight or a disk. The disk may include a tubular spacer so that the disk is spaced away from the body.
