Abstract: A heel guard for guarding a heel of a shoe includes a barrier having a base wall and a sidewall. The sidewall is coupled to and extends upwardly from the base wall. The sidewall also extends along a perimeter of the base wall and has a U-shape wherein a concave surface of the sidewall is configured to abut and extend around the heel of the shoe. The barrier is configured to be positionable to support the shoe over a floor surface. A clip is coupled to a top edge of the sidewall and extends from the sidewall over and toward the base wall. The clip is configured to extend into an opening of the shoe when the barrier is used to support the shoe to retain the sidewall against the heel.

Abstract: A method for manufacturing an environmental barrier comprising the steps of coating a rare earth silicate powder with a precursor of a densification agent in order to form a rare earth silicate powder coated with the precursor of the densification agent, thermally spraying the coated powder onto a substrate in order to obtain an at least partially amorphous environmental barrier on the substrate and thermally treating the environmental barrier in order to crystallize and densify the environmental barrier.

Abstract: A system for purchasing items, such as hair products is described. The system includes an electronic device and a kiosk. A user can take a selfie from the electronic device. A software converts the picture to an emoji and provide user with different products available. The user can choose a product of interest and collect it from a kiosk vending machine (KVM) located at a place of interest or any nearby location.

Abstract: An interchangeable filter facemask apparatus for providing a variety of different filtration options includes a mask body including a body perimeter portion, a sidewall extending from the body perimeter portion, a body left side, a body right side, a body nose side, a body chin side, a body outside, and a body inside. The sidewall has a filter aperture extending from the body outside through the body inside. A headband is coupled to the mask body. A body engagement member is coupled to the body outside adjacent an aperture perimeter of the filter aperture. Each of a plurality of filters has a filter outside, a filter inside, and a filter perimeter. Each filter has a filter engagement member coupled to the filter inside adjacent the filter perimeter. The filter engagement member is selectively engageable with the body engagement member to cover the filter aperture with the filter.

Abstract: A diagnostic tool for evaluating a patient's oculomotor system includes tests for measuring the amount of a patient's heterophoria and fixation disparity and determining whether these two measurements bear a normal or abnormal relationship. If the results of these tests do not bear a normal relationship, it is concluded that an oculomotor imbalance or dysfunction exists and further analysis should be performed to determine the precise nature of the dysfunction. The diagnostic tool may comprise a near-point card on which tests for heterophoria and fixation disparity are printed, as well as a graph indicating the expected or normal relationship between the results of these two tests. Additional diagnostic tests may be included on the card.
