An electronic interval timer in a regular dodecahedron case is described. The timer is set by orienting the timer so that the face with the time desired is uppermost. The timer is free of buttons, switches, and electronic displays. It is sealed for ruggedness and water-resistance, and free of a battery door. Detection of motion, taps, and orientation is via an accelerometer and a processor; it is free of mechanical motion and orientation switches. The timer indicates start and end of set time intervals with speech announcements or tones. Two time intervals may run concurrently by orienting the timer to a second time. The timer may be programmed via an orientation sequence. Taps may be used to request a time remaining announcement or to set volume. Functions include a stopwatch. Shells have seam lines on polyhedral edges and pin-and-socket connections for strength. A molded air-gap provides for pressure equalization while maintaining water resistance.

Electronic timer

An electronic interval timer in a dodecahedron case is described. The timer is set by turning uppermost one of 11 faces; and reset by turning uppermost the 12face. In one embodiment, the timer is free of buttons, knobs, springs, time displays, electronic visual indicators and openings in the case. Time interval completion is announced via audible tones or speech. An aggregate time interval may be set equal to the sum of legends on more than one face. The timer detects carrying such that a running time interval is not modified. The timer may be programmed via a sequence of uppermost sides. Modes may be selected via shaking or tapping. Time remaining may be announced, an interval cleared, or an interval restarted responsive to detected motion. Other polyhedral shapes may be used. Claims include a method of setting a time interval; and specific ordering of face legends.
