Abstract: Aspects of the present disclosure relate to color printing calibration. In a particular example, an apparatus includes a media sensor and a formatter. The media sensor may collect spectral data from light reflected off a print material. The media sensor may include a light source to illuminate a portion of the print material, a diffractor to diffract light reflected off of the print material, and a photo-detector to obtain the spectral data from the light reflected off the print material. The formatter may identify a white-point of the print material using the spectral data and configure color concentrations in the apparatus based on the identified white-point of the print material.

Abstract: The present invention is generally directed to a swim fin generally including a fin blade and a bootie, the bootie including a foot pocket configured to receive a user's foot and ankle, the foot pocket attached to the top surface of the fin blade; and a strap system including one or more straps pulling the user's foot and ankle into the foot pocket toward the distal edge of the fin blade and down against a top surface of the fin blade. Some aspects of the present invention may also include a foot pocket formed from a first portion having a first elastic characteristic connected to the top surface of the fin blade; and a second portion having a second elastic characteristic portion disposed at least on a portion of the top surface of the foot pocket, the second elastic characteristic being greater than the first elastic characteristic.

Abstract: A system to provide protection for plant roots and bulbs from burrowing animals is presented. Body of system is manufactured as a single contiguous part, which in certain embodiments is flat for the cheapest manufacture and storage. In such embodiments, the part is wrapped, before installation, about an axis to form a conical-annulus with a bottom closure structure. In other embodiments, the part is manufactured in its installation form. An upper portion of the structure incorporates a mechanism by which the plant protection system is rigidly integrated with irrigation/nutrient delivery system. Lower portion of structure is perforated to allow for root growth and drainage while still providing protection of bulb or plant root core.
