The at least one processor is configured to control the display so as to display an elapsed time, switching between (i) a first display mode for display of the elapsed time cumulatively by causing, upon resumption of display, movement of the pointer that inherits a previous display time and (ii) a second display mode for display of the elapsed time non-cumulatively by causing, upon resumption of display, movement of the pointer that does not inherit the previous display time. The movement of the pointer controlled by the at least one processor is such that the first display mode and the second display mode differ from each other in a way of movement that indicates how the pointer moves.

Abstract: A broadside coupled connector assembly has two sets of conductors, each separate planes. By providing the same path lengths, there is no skew between the conductors of the differential pair and the impedance of those conductors is identical. The conductor sets are formed by embedding the first set of conductors in an insulated housing having a top surface with channels. The second set of conductors is placed within the channels so that no air gaps form between the two sets of conductors. A second insulated housing is filled over the second set of conductors and into the channels to form a completed wafer. The ends of the conductors are received in a blade housing. Differential and ground pairs of blades have one end that extends through the bottom of the housing having a small footprint. An opposite end of the pairs of blades diverge to connect with the wafers.

Abstract: A method for measuring the medium frequency of a digital signal derived from a reference periodic signal generated by an electronic oscillator (quartz oscillator) forming a timepiece (2) which includes an analogue time display device and a continuous rotation electromechanical transducer (generator or continuous rotation motor) which is kinematically linked to this display device and wherein the medium rotational speed is regulated by a regulation device.

The measurement method makes it possible to determine the rate of the timepiece and the precision of the electronic oscillator based on regulation impulses detected by a magnetic sensor (72) and over a measurement period limited to the duration of an inhibition cycle of periods of the reference periodic signal.
