摘要:
Distress signal transmitters of the present invention are designed to maximize the chance for a victim to survive an accident, and minimize the time for a rescue party to find a victim. The preferred embodiments of the distress signal transmitters of the present invention are to be self-powered, self-activated, and to remain fully functional when dropped into salt water. This will allow the Radio Frequency (RF) distress signals to be sent over a long distance, even if the user is unconscious or severely injured. Furthermore, a set of coordinates determined by a Global Positioning System will be transmitted with the S.O.S message in order for search parties to quickly and efficiently pinpoint the location of the victim(s).

Synchronized mechanical switches are configured to support electrical switching circuits operating at frequencies equal to or higher than the frequency of the primary AC power supply. Due to near perfect impedances of mechanical switches as well as accurate timing control mechanisms, the mechanical switching circuits provide timely electrical connections to the terminals of the primary AC power supply to generate proper waveforms suitable to power next stage electrical circuits without the need to use semiconductor devices.

The preferred embodiments of the present invention changes the switch control mechanisms of switched-mode power converter circuits. Instead of controlling the duty cycle of switch control signals, the preferred embodiments of the present invention controls electrical switches based on the voltage level on the fire line of AC main power source. The resulting power converter circuits operates at better power efficiency while achieving significantly better space/cost efficiency, and they are small enough while powerful enough to be embedded into battery powered mobile devices.

Long existing performance, noise, and power consumption problems of known output drivers are solved by using n-channel transistors as pull up transistors and/or p-channel transistors as pull down transistors for high performance output drivers. On-die termination-circuit-branches provide effective anti-reflection functions for multiple chips connected to the same transmission line(s).
