Latest Patents
Hellman's latest patents include a "Low Current Voltage Regulator Circuit" and a "Power Supply Switching Arrangement." The Low Current Voltage Regulator Circuit is designed to regulate energy delivered to power-consuming devices operating at low current levels. This innovative power supply utilizes a light-emitting diode (LED), preferably a gallium arsenide diode, to maintain a constant voltage within a current range of 10 to 25 microamps. This design offers improved performance compared to traditional circuits that use zener diodes, making it particularly suitable for line-powered telecommunication devices.
The Power Supply Switching Arrangement addresses the challenges posed by power supply interruptions. In scenarios where maintaining power is critical, a secondary battery is employed to ensure continuity when the load voltage drops below a predetermined threshold. The arrangement utilizes MOS transistors to interconnect primary and secondary voltage supplies with the load, ensuring that only one MOS transistor is active at any given time. This design minimizes the risk of power loss during switching, making it advantageous for low power applications that utilize lithium batteries.
