Is your Seiko Kinetic watch failing to charge as it should? Does your Seiko Kinetic watch stop during the night? Does your power reserve indicator only show ‘5’ or ’10’ seconds of charge, no matter how much you ‘shake’ or ‘swing’ the watch to charge the capacitor? Is your second hand ‘stepping’ two-seconds, indicating a low charge? Have you already had a Seiko Kinetic watch repair only to have the original problem come back in a few weeks or months?

When a modulated IR beam is turned on and off to transmit data, the cleanest signal is obtained when the digital clock and the modulating carrier are synchronous. The smallest unit of time is taken to be one period of the IR modulation cycle and the duration of a bit is a constant number of such cycles. The datasheet for the TSOP would then call for the representation of a “1” to be a pulse of 6 cycles followed by 10 cycles of silence.
To satisfy this, we stretch the start pulse to 10 cycles instead of 6. Stretching the start pulse by 4 cycles makes each bit frame last cycles instead of The integrated IR receivers for consumer electronics aren’t always suited for continuous serial transmission. They are fine-tuned for noise-rejection in the remote control of consumer-electronics devices, like televisions and such, where the duration of the IR transmission is a small fraction of a second.
To maximize sensitivity, they have maximum gain when waiting to receive a modulated IR signal. The gain decreases when IR is received to avoid swamping the circuit. If a long transmission is attempted, the gain may become so low that radiation will no longer be detected at all.
