Abstract: In an embodiment, an apparatus comprises a processor, and a memory that stores a program. The program, when executed by the processor, directs the processor to perform a method including the following steps: receiving an encrypted query, in which the query indicates at least one security, and at least one price; determining whether the encrypted query corresponds to any order in an encrypted data set that represents orders; outputting a response to the query, in which the response indicates whether the encrypted query corresponds to any order in an encrypted data set that represents orders; receiving order data that represents the orders; and encrypting the order data to yield the encrypted data set that represents orders.

Abstract: A pet waste collection system comprising a frame, a mounting bracket, a spool, and a sensor. The frame defines a floor with a first end and a second end. The floor may be configured to receive waste from a pet. The mounting bracket may be located on the first end of the floor and configured to receive a wrapper cartridge. The spool may be located on the second end of the floor and configured to allow a film to be drawn from the wrapper cartridge across the floor and to roll the film around the spool. The sensor is configured to detect the presence of pet waste at the film proximate the floor.

Abstract: The present invention includes a label for a nursery container. The label includes a protective first layer having a first adhesive layer affixed to at least a portion of a second side of the protective first layer. The label also includes a second layer having a top surface and a bottom surface, the top surface contacting at least a portion of the first adhesive layer. The label further includes a base adhesive layer having a first side and a second side, the first side affixed to at least a portion of the bottom surface of the second layer and the second side of the base adhesive affixed to the container. In addition, at least a portion of the first adhesive layer is affixed to the container. A method for creating the label is also defined.
