摘要： An arbitrary number of member computer stations are inter-connected by a "party" communication network. Each member station is normally in a high impedance Monitor Mode, for monitoring in-coming messages. The incoming messages latch the monitoring stations into a Receive Only Mode for preventing "interrupts" of on-going communications. Each station continuously monitors the input impedance from the network, to determine when the network is available for transmission. Member stations may enter the low impedance Transmit Mode only when the network is available, because all of the other stations are in the Monitor Mode. A high Z from the network indicates to each station that the network is available. A low Z indicates that another station is in the transmit Mode, and is in control of the network. The random entry of two (or more) parties at the same time is resolved by a Pre-Transmission Test Cycle. Full transmit status with actual data transmission, cannot be obtained unless the Test code transmission reveals a high network impedance indicating that the network is available. In the "two-party" start situation, each party senses the other parties low Transmit Mode impedance. Both parties drop back to the Monitor Mode, and a data "collision" is avoided.
摘要翻译：任意数量的成员计算机站由“派对”通信网络互连。每个成员站通常处于高阻抗监视模式，用于监视即将发送的消息。传入的消息将监控站锁定到仅接收模式，以防止正在进行的通信的“中断”。每个站持续监控来自网络的输入阻抗，以确定网络何时可用于传输。只有当网络可用时，会员站才能进入低阻抗发射模式，因为所有其他电台都处于监视模式。来自网络的高Z向每个站指示网络可用。低Z表示另一个站处于发送模式，并且在网络的控制中。两个（或多个）方在同一时间的随机进入通过预传输测试周期来解决。完全发送状态与实际数据传输不能获得，除非测试代码传输显示高网络阻抗指示网络可用。在“双方”启动的情况下，各方感觉对方低传输模式阻抗。双方回到监控模式，避免数据“碰撞”。

摘要： A system, method and apparatus for charging rechargeable battery packs having redundant safety systems. A battery charger has a temperature sensor at a negative charging terminal for determining the charge condition of a rechargeable battery pack and controlling a charging current. The battery charger has a microcontroller to control the charging of the rechargeable battery pack using a fast charge current or a trickle charge current. Independent safety systems provide safe operation of the battery charger if the microcontroller operation fails. A rechargeable battery pack has a pair of openings to allow direct contact to a positive pole and a negative pole of the end batteries for improved temperature sensing by a battery charger.
