The present invention comprises a plurality of injectable hollow particulate fillers suspended in a biocompatible fluid carrier to significantly improve the clumping resistance and injectability of the composition. The hollow particulate fillers have a lower effective density and are able to suspend in the carrier without precipitation. The loss of skin volume as a result of aging, diseases, weight loss, and injury can lead to uneven skin surface (e.g. wrinkle, etc.). The uneven skin can be repaired by injecting appropriate amount of hollow fillers underneath the skin. Some cases of urinary incontinence occur when the resistance to urine flow has decreased excessively. Continence is restored by injecting the present invention to the urethra tissue to increase resistance to urine outflow. Similarly, the present invention allows for the control of gastric fluid reflux by submucosal injections of the fillers to the esophageal-gastric and gastric-pyloric junction. For patients with vesicoureteral reflux, it can be treated by injection of the present invention into patients' ureteral tissue. This invention can also be used to repair defective or inadequately functioning muscles of the anal sphincter by administering an effective amount of injectable hollow fillers into the defect or anal sinuses.

An edge-lit panel features extractor patterns that produce uniform illumination. The effective density of extractor pattern pixels is adjusted to achieve uniform illumination. A method of adjusting the effective pixel density of extractor pattern pixels to achieve uniform illumination entails adjusting areas of darkness of a grayscale image, then producing a binary image by dithering the grayscale image, and applying an extractor pattern corresponding to the binary image to a surface of the panel. The extractor pixels correspond to pixels of the binary image derived from a dithered grayscale image, with the darkness of the grayscale image increasing with distance from the light source. Effective pixel density is increased to compensate for attenuated output in dim areas. By adjusting gray shading darkness of a grayscale image, pixel density can be adjusted to achieve uniform light emission. The extractor pixels may be applied using a radiation curable ink, which can be used in high speed inkjet printers that can achieve production speeds. The resulting print is waterproof, embossed and vibrant.
