摘要:
A balance for a horological movement includes rigid portions consisting of a hub defining the pivot axis of the balance, a felloe, four arms connecting the felloe to the hub, and including four slots for receiving and gripping in position an inertia-block, each slot being delimited by an arm and by an elastic arm including a first end integral with the arm, and a second distal end free in relation to the hub, to the arm, and to the felloe sector. The balance includes two pairs of inertia-blocks, each pair of inertia-blocks having different masses to ensure different adjusting powers, a first pair of inertia-blocks for a basic adjustment, and second pair of inertia-blocks for a precise adjustment.

摘要:
Systems and methods for operating with oscillators configured to produce an oscillating signal having an arbitrary frequency are described. The frequency of the oscillating signal may be shifted to remove its arbitrary nature by application of multiple tuning signals or values to the oscillator. Alternatively, the arbitrary frequency may be accommodated by adjusting operation one or more components of a circuit receiving the oscillating signal.

A method for a portable device is disclosed. A reference clock is provided. A first time value and a first index are recording at a first time point. A second index is recorded at a second time point. The first time point and the second time point are counted according to the reference clock. The first index and the second index are calculated. A second time value is set according to the calculating result.
摘要:
A frequency divider circuit uses a base counter to frequency divide a clock signal with period T by an integer value N and employs a cyclic rotational select circuit to select among multiple equally phase shifted signals of a multiple phase clock to generate a fractional term P/k where P is variable from 0 to k−1. The counter counts an output clock that corresponds to the output of a multiplexer selecting from among the multiple clock phases. Depending on the desired fractional term, after N counts of the output clock phases of the multiple phase clock are selected glitch free by rotationally selecting a first phase, and skipping either 0, 1, 2 . . . up to k−1 sequential phases to generate fractional terms 0, 1/k, 2/k, 3/k . . . k−1/k, respectively, thus providing frequency division corresponding to N+P/k where P may be varied from 0 to k−1.

The time-setting device includes a stem (8) capable of driving by friction a motion work wheel (29). The stem (8) ends in a knob (31) which rests against an annular flange (32) made under the motion work wheel. When the stem (8) is in a pushed in position, the knob runs idle. When this stem is pulled out, the knob drives the motion work to set the time of the hour (23) and minute (22) hands.

A method for resetting a real-time clock of a pen-based computer system characterized by the steps of: displaying an image of an analog clock face with an hour hand and a minute hand on the screen of a pen-based computer system; determining whether a clock-setting stroke has been made with a stylus upon the image of the analog clock face; resetting the real-time clock to correspond to the clock-setting stroke; and moving at least one of the hour hand and the minute hand in response to the clock-setting stroke. An apparatus for resetting a real-time clock of a pen-based computer system is characterized by: a digital processor; a real-time clock coupled to the digital processor; a screen assembly coupled to the digital processor; a display mechanism for displaying an image of an analog clock on the screen assembly; a detection mechanism for detecting a clock-resetting stroke on the image of the analog clock by a stylus; and a resetting mechanism for resetting the real-time clock in response to the clock-resetting stroke.
