Abstract: System and methods for managing predictions of outcomes in live events in real time on a computing platform are disclosed herein. The system allows users to predict outcomes of sub-events, such as plays, in real time during a live event, such as a football game, based on and in response to actual actions occurring in the live event. The user may view the live event in-person, on television, or through the Internet. The system is meant to reward those users having more knowledge and skill regarding a particular live event.

Abstract: What is provided is a water filter assembly comprising a filter cartridge. The filter cartridge comprises a filter head comprising an inlet port; an outlet port; and a filter key integrally formed on the filter head between the inlet port and the outlet port. The filter key consists of exactly one laterally extending finger that is integrally formed on the filter key. The filter key is integral with the filter head as a one piece construction to form a more water-tight seal on the filter cartridge and help prevent the filter key from being separated from the filter cartridge. The finger may have a substantially polygon-shaped cross-section to more efficiently and quickly interlock the filter key with components on a filter receiver. As a result, the filter cartridge may be readily attached to and removed from the filter, while being securely enough engaged to avoid unwanted uncoupling.
