    • Mileage tracking devices track a vehicle's mileage. A top is hingedly attached to a bottom in a “clamshell” design. The front of the top has an LCD touchscreen, and the front of the bottom has a keypad. The rear of the top has a solar panel, and the rear of the bottom has a battery compartment enclosing a rechargeable battery. One side of the bottom has a USB port, and the opposing side of the bottom has a power port that receives one end of a car charger. Voice recognition software and data are stored in memory accessed by a microprocessor. The mileage tracking device provides calculator, calendar, address book, mileage log, and car maintenance functions. The LCD touchscreen displays the current date and time and the level of charge of the rechargeable battery.
    • 里程跟踪设备跟踪车辆的里程。 顶部以“蛤壳”设计铰接在底部。 顶部的前部有一个LCD触摸屏,底部的前部有一个键盘。 顶部的后部具有太阳能面板,底部的后部具有包围可再充电电池的电池室。 底部的一侧具有USB端口,并且底部的相对侧具有接收车载充电器的一端的电源端口。 语音识别软件和数据存储在由微处理器访问的存储器中。 里程跟踪设备提供计算器,日历,地址簿,里程日志和汽车维护功能。 LCD触摸屏显示当前的日期和时间以及可充电电池的电量。

    • Apparatus is provided for the virtual expansion of the power providing capacity of a power supply, e.g., for a stereophonic audio system with a given number of channels which may be selectively increased to provide a surround audio system. A plurality of amplifiers, each having an adjustable gain, are powered from the power supply. The current drawn from the power supply is sensed. When additional amplifiers are activated, the total amount of power drawn by all of the amplifiers can exceed a predetermined level which corresponds to the original plurality of amplifiers. However, when it is sensed that the total amount of power drawn exceeds the predetermined level, the gain of all of the amplifiers is reduced so that the power drawn from the power supply does not exceed the predetermined level. Thus, the virtual power providing capacity of the power supply is expanded to power the additional amplifiers.
    • 提供了用于虚拟扩展电源的功率提供能力的装置,例如,对于具有给定数量的信道的立体声音频系统,其可以选择性地增加以提供环绕音频系统。 每个具有可调节增益的多个放大器由电源供电。 检测从电源抽出的电流。 当额外的放大器被激活时,所有放大器的总功率量可以超过对应于原来的多个放大器的预定电平。 然而,当感测到所提取的总功率超过预定电平时,所有放大器的增益被减小,使得从电源提取的功率不超过预定电平。 因此,电源的虚拟功率提供能力被扩展以对附加放大器供电。
