Abstract

A technique for testing and verifying function of a system conveniently and precisely under different battery capacities is disclosed. The system includes battery powered components of an X-ray machine upgrade kit. The test and verification technique employs a power module, a system management bus (SMBUS) communication control board and a personal computer (PC). The PC sends the battery capacity test command to SMBUS communication control board, followed by powering on equipment under test (EUT). EUT then sends a battery capacity inquiry to SMBUS communication control board. The control board replies the battery capacity which is set by PC to EUT when the control board receives the battery capacity inquiry from EUT. Finally, function of the EUT is watched under related battery capacity and result is recorded.

DIFFERENT BATTERY CAPACITY VERIFICATION METHOD USED ON A DIGITAL UPGRADE KIT FOR AN ANALOGY X-RAY MACHINE

BACKGROUND

The present invention relates generally to an X-ray machine upgrade kit and more particularly to a technique for testing and verifying function of the battery powered components of the X-ray machine upgrade kit at different battery capacities.

Generally, an X-ray machine upgrade kit system includes a workstation, a dock, a wireless access point (AP) and a wireless detector, among others. Battery powered components, such as the wireless detector and the portable workstation are powered by a battery pack. However, conventional techniques do not precisely verify function of the battery powered components at different battery capacities.

A strictly followed procedure to verify function of the battery powered components requires testing some critical points of battery capacity. For example, when battery capacity is 3% of full capacity, function of the system requires verification at a battery capacity of 3+-0.1%, more specifically, at three different percentages, i.e., 2.9%, 3.0% and 3.1%. Similarly, for another critical battery point, such as, when battery capacity is 5% of full capacity, function of the system requires verification under 4.9%、5.0% and 5.1%. Similar verification of function of the system is conducted at other cut-off points of battery capacity. However, acquiring exact battery capacity very difficult. In fact, even if the critical point of battery capacity is acquired, for example, 3%, the battery capacity changes while the battery pack is installed and powers the system. Also, some time is required to complete the test when the battery capacity changes from the critical point. Therefore, verifying the system at an accurate battery capacity listed in the test procedure or specification remains a challenge.

It would be desirable to have a technique to provide precise and efficient verification for system function at different battery capacities.

DETAILED DESCRIPTION

A technique for testing and verifying function of a system conveniently and precisely under different battery capacities is disclosed. The system includes battery powered components of an X-ray machine upgrade kit. The test and verification technique employs a power module, a system management bus (SMBUS) communication control board and a personal computer (PC). 

A battery pack includes a smart communication interface, such as SMBUS. SMBUS eases reading all battery information, such as, battery capacity, battery temperature, charge or discharge status, voltage and current information, among others.

The power module provides power to equipment under test (EUT). The power module may be an external direct cu...
