Abstract: A coffee brewing apparatus and method that produces coffee using an agitation and cold brew operation. A high temperature strike stage with agitation is followed by a cold brew stage, with a displacement pump configured to transfer the coffee oils and extracts, shortening the time necessary to achieve a brew cycle. The brewing cycle of the present invention preferably uses a six stage sequence that includes introduction of strike water, agitation, bloom, brew water introduction, extraction, and dilution. The various stages are performed using a brewing system that includes an agitation system, a displacement pump, and a filtering system used to extract the oils and extracts of the coffee for brewing.

Abstract: An interactive multimode tracking system and method is disclosed. In general, the tracking system comprises a central office that interactively communicates with various portable tracking units over at least two communication networks. The multiple communication networks help maintain a connection with the tracking units. The central office can also actively manage the information provided a user of the tracking unit. This allows the central office to change the route of the user based on changing conditions.

Abstract: A concave for a combine harvester includes a body consisting of a grid of straight longitudinal bars arranged in a concave configuration. Each of the longitudinal bars have a leading face, a trailing face, and an upper extremity. At least one of the longitudinal bars has a longitudinal cavity positioned along the leading face at the upper extremity. A wear resistant insert is positioned in the longitudinal cavity. The wear resistant insert is detachably secured to and receives underlying support from the said at least one of the longitudinal bars. The wear resistant insert provides a replaceable leading edge.
