    • A haptic gaming device includes an integral internal power supply adapted to be connected directly to alternating current (AC) line power. The haptic gaming device, a disclosed example of which is a force feedback joystick, provides a feedback force to a user gripping a control handle of the device. The force on the control handle is produced by one or more electrical motors within the base of the device. Electrical power for the motors is provided by the integral internal power supply and is regulated to accommodate a relatively wide range of input AC line voltage. The power supply includes a pulse width modulated switching control that produces pulses of direct current (DC), which are applied to a first primary winding of a transformer in the power supply. A second primary winding in the transformer produces a feedback signal employed to control a pulse width modulated switching (PWM) control, which varies a width of the DC pulses applied to the first primary winding so that the voltage output from a secondary winding of the transformer remains within a desired range. Because the integral internal power supply is relatively compact and includes only a few components, it has a low cost and readily fits within the base of the joystick.
    • 触觉游戏装置包括适于直接连接到交流(AC)线路功率的整体内部电源。 触觉游戏装置(其公开的示例是力反馈操纵杆)向抓握装置的控制手柄的用户提供反馈力。 控制手柄上的力由装置底部内的一个或多个电动马达产生。 电机的电源由集成内部电源提供,并被调节以适应相对较宽范围的输入交流线路电压。 电源包括产生直流电(DC)的脉冲宽度调制的开关控制,其被施加到电源中的变压器的第一初级绕组。 变压器中的第二初级绕组产生用于控制脉宽调制开关(PWM)控制的反馈信号,脉冲宽度调制开关(PWM)控制改变施加到第一初级绕组的直流脉冲的宽度,使得从变压器的次级绕组输出的电压 保持在期望的范围内。 因为整体内部电源相对紧凑,并且仅包括少量部件,所以成本低并且容易地安装在操纵杆的基座内。
