Abstract: A computing device retrieves a stabilized weight and a weight-based item count for one or more items to be purchased. Responsive to retrieving the stabilized weight, the computing device retrieves an image-based item count and an expected weight based on the image-based item count for the one or more items to be purchased. The computing device selects between authorizing and blocking checkout of the one or more items based on the weight-based item count, the image-based item count, the stabilized weight, and the expected weight.

Abstract: An improved toilet seat cover can be easily installed and disposed of by a user, and protects the user from potentially contagious contact with a toilet. According to an embodiment, the cover is composed of a plastic material, and includes a main body portion. A resilient material, such as an elastic band, extends around an outer periphery of the main body portion for attaching the cover to the toilet seat. A perforated center portion is capable of being removed by a user for providing an opening into an interior of a toilet bowl and enabling the user to manipulate the cover to a desired position upon the toilet seat.
