Title: Innovations by James L Estes, Jr.

Introduction

James L Estes, Jr. is a notable inventor based in Lawrenceville, GA (US). He has made significant contributions to the field of battery technology, holding 2 patents that showcase his innovative spirit and technical expertise.

Latest Patents

One of his latest inventions is the "Low Power Enable Circuit." This invention is a system and method designed to cause a rechargeable battery pack to enter a low power mode. The system includes a resistive divider, a switch, a battery cell, and a safety integrated circuit. When an external voltage is applied to the resistive divider, the switch turns on. With the switch activated, the safety integrated circuit senses only a fraction of the cell voltage, thereby putting the battery pack into a low power, or sleep mode. The battery can be returned to normal mode by connecting a charger to the battery pack.

Another significant patent is the "Battery Pack Having a Hibernate Circuit." This battery pack includes a battery cell, a power switch, a regulator circuit, a control circuit, an electronic drive switch, and a mechanical driver switch. The battery pack is placed in hibernate mode by sending a hibernate message to the control circuit from an external device. The control circuit removes a control signal from the electronic driver switch, causing the power switch to open and removing power from the regulator circuit and all attached circuitry. No current flows from the battery cell past the opened power switch, placing the battery pack in hibernate mode. To wake up the battery pack, the mechanical driver switch is actuated by a user, allowing current and voltage from the battery cell to power up the regulator circuit and control circuit.
