Abstract: A method of setting a multimode electronic device operable in a current mode, a mode setting mode and a next mode. If a predetermined number of electrical signals are generated prior to the expiration of a predetermined period of time, the electronic device exits the current mode and enters the next mode. Locking conditions are also provided to assist in ensuring the device remains in a “home,” such as the time-of-day, mode. In one embodiment, the switching mechanism includes a rotating setting stem and the electronic device is a watch.

Abstract: A three channel electronically tunable filter arrangement for selecting radio frequency signals to be processed in a monopulse receiver is disclosed. Each channel of the disclosed filter arrangement includes an yttrium-iron-garnet (YIG) filter disposed in a common structure so that the resonant frequency of each channel may be controlled by the magnetic field of a single electromagnet. Also disclosed is an alignment method whereby the response of the YIG filter in each channel may be independently adjusted to eliminate any substantial imbalance between channels as the strength of the magnetic field is changed to change the resonant frequencies of such filters.
