Abstract: Grinders, analyzers, and related technologies are described herein. The grinders can hold foodstuff that is periodically ground. The analyzers can analyze the foodstuff to determine information about the state of the foodstuff. Algorithms can be used to determine how to process the foodstuff, how to use the foodstuff, and/or when to discard the foodstuff. The grinder can be a portable, rechargeable electric coffee grinder configured to monitor the freshness of the coffee beans. When coffee beans become stale, they can be discarded and the coffee grinder can be refilled with fresh coffee beans.

Abstract: A travel receptacle comprising a receptacle for holding a liquid and a lid for selectively closing the receptacle. The lid includes a first piece for engaging the top of the receptacle, the first piece having an impermeable portion which blocks the passage of the liquid therethrough and a first opening for allowing the passage of the liquid therethrough; and a second piece having an impermeable portion which blocks the passage of the liquid therethrough and a second opening for allowing the passage of the liquid therethrough. At least one of the first piece and the second piece is movable with respect to the other, between an open position in which the first and second openings align to allow passage of the liquid therethrough and a closed position in which the first and second openings are not aligned, thereby blocking passage of the liquid.
