摘要： A battery charging system for multiple series connected battery cells which includes a plurality of shunt regulators, adapted to be connected in parallel with each of the cells. The voltage of each cell is monitored during charging. When a cell is fully charged, excess charging current is shunted around the fully charged cell to enable the remaining cells to continue to charge. Circuitry is also provided to prevent the charging system from discharging the cells when the battery is not being charged. In an alternative battery charging system, a voltage source is connected across each of the serially connected batteries. Each voltage source is capable of sourcing or sending charging current. During charging conditions, the voltage sources source charging current to the cells. In order to prevent fully charged cells from being overcharged, the voltage across each cell is monitored. When the cell becomes fully charged, as indicated by the cell voltage, excess charging current is sunk to ground. In another embodiment of the invention, a rechargeable battery, formed from multiple internally series connected cells is provided with an integral battery charger within the battery housing.

摘要： A flexible multimedia presentation system is configured to be releasably secured to a portable personal computer to provide additional features, such as a PCMCIA interface, a port replicator and other options. The system is configured to enable the unit to be rather easily transported as a unit. A retractable handle is provided which further facilitates transport of the unit. In order to provide enhanced flexibility of the flexible multimedia presentation system, the system includes a PCMCIA interface, as well as replicates the various I/O ports on the rear of the portable personal computer. By replicating the I/O ports on the portable personal computer, external I/O devices, such as an external monitor, keyboard, mouse and printer can be used when the portable personal computer is docked to the flexible multimedia presentation system. In the event that the personal computer is turned off; or the personal is not docked to the system; or the power supply within the system is unavailable, the various data, address and control signals in the flexible multimedia system are disconnected to prevent any loss of data or any damage to the personal computer and the flexible multimedia system.

摘要： A dedicated network expansion unit includes a processor and a dedicated hard disk drive, and has two bays which each can receive one of a further hard disk drive, a floppy disk drive, a CD-ROM drive, and a tape drive. The unit has no manual input mechanism, and no display for text or graphics. The unit can be connected to one or more communications link through Ethernet connectors, a PCMCIA modem card, a PCMCIA token ring card, or a parallel connector. Following power-up or a reset, the unit automatically detects the types of devices present and the types of communications link connected to it, and automatically configures its software to operate properly with these devices and links, without user interaction. Special software routines are provided for the unit and a remote computer to permit a conventional backup program in the remote computer to effect a backup operation within the expansion unit using ASPI commands. A further program effects a software interface between at least two communications link and a conventional network driver program designed to communicate with a single network.

摘要： A computer system includes a flash memory device for storing BIOS code. The BIOS code is stored in an unprotected area of the flash memory. A boot block, stored in a protected area of the flash memory, is used for rebooting the computer system in the event that the flash memory device becomes corrupted. During normal operation, the BIOS code is updated using a radio link. If the BIOS is corrupted while being updated, a recovery routine stored in the boot block is executed. The recovery routine permits the corrupted BIOS to be reprogrammed using a serial interface instead of the radio link.

摘要： A power supply system, for example, for use with a portable personal computer, includes a smart battery pack and a charging system. The smart battery pack is provided with a dedicated microcontroller for controlling the charging level of the battery charger system. In particular, the status of the battery including the voltage and temperature of the battery is applied to the microcontroller along with a signal representative of the current load demand of the computer system. The microcontroller, in turn, provides a control signal in the form of fixed frequency, variable duty cycle pulse width modulated (PWM) signal for controlling the charging level of the battery charger system. The duty cycle of the PWM signal is used to regulate the charging current supplied by the battery charger. In particular, the DC value of the PWM signal is used as a reference to control the charging current of the regulator to provide a variable output charging current with a relatively wide current range. As such, the battery charger is adapted to efficiently utilize the residual capacity of the battery charger system for optimizing charging of the battery packs during all operating conditions of the computer system. Moreover, the use of a PWM signal from the battery pack to control the battery charger enables a single type of battery charger to be utilized for various battery technologies.

摘要： A computer system employs a process on warm boot which obviates the need to copy code in non-volatile memory to volatile memory; a normal function in a warm boot process. The computer system checks a warm boot flag which indicates that the code was previously copied on cold boot. By avoiding copying this already copied code and executing directly from the volatile memory considerable time is saved. Since BIOS code is typically on the order of 10K bytes, elimination of the necessity to rewrite BIOS and vectoring directly to BIOS image file in RAM saves on the order of ten thousand clock cycles.
摘要翻译：计算机系统采用热启动的过程，其消除了将非易失性存储器中的代码复制到易失性存储器的需要; 在热启动过程中的正常功能。计算机系统检查一个热启动标志，指示该代码以前是在冷启动时复制的。通过避免复制已经复制的代码并直接从易失性存储器执行，可以节省大量时间。由于BIOS代码通常在10K字节的数量级上，所以不需要重新编写BIOS并直接向导到RAM中的BIOS映像文件就可以节省一万个时钟周期。
