Abstract: Means for containing and handling pet litter, wherein a reusable, collapsible frame assembly is used cooperatively with a flexible trash bag to provide a structure for enclosing a litter container while in use, allowing the pet caregiver to dispose of the entire litter container without touching it. The reusable, collapsible frame assembly is designed to support the trash bag while in use, and to be partially or completely compressed for removal so that the litter, bag, and optionally the litter container can be disposed of together without requiring the animal caregiver to touch the contents.

Abstract: An electronic device for calculating, storing and indicating the scores and related information for a game of tennis is described. The circuit provides for the special requirements of tennis and similar games by recognizing the existence of an endgame condition such as "deuce" in tennis and registering each new score as a function of the previous score and the point most recently won. Both up-down counters and decoders using non-volatile memory, including "read-only memory" (ROM) are disclosed for the point-calculation function, and a display encoder is described which efficiently provides for the display of alphanumeric scores, including "deuce" and "advantage" conditions. The invention includes features for indicating court change requirements, elapsed time, time of day, and display emphasis when a game is won. All score calculations are subject to a clear-entry feature to rectify operating error.
