    • In a public cordless telephone system, a cordless telephone handset unit requests and establishes a communications link with a public base unit served by a desired local service provider whenever possible. By generating a service request containing a specific carrier request code, the handset unit selectively identifies an available public base unit served by the desired local service provider and then establishes a communications link with this base unit. In response to receiving the service request from the handset unit, all public base units operated by the chosen service provider respond by providing a first acknowledgment signal. All other public base units respond by providing a second acknowledgment signal. When both such signals are received, the handset unit responds only to the first acknowledgment signal and establishes a communications link with the first base unit providing this signal. When only the second acknowledgment signal is received, the handset unit responds by establishing a communications link with the first base unit providing this second acknowledgment signal. When communications is established with a base unit providing the second acknowledgment signal, an alerting signal is generated at the handset unit thereby informing the user that even though he or she is able to make a telephone call, the desired local service provider was not reached. Collision avoidance between public base units while supporting this operation may be provided by assigning a specific one of a plurality of times during which each public base unit may respond to the service request from the handset unit.
    • 在公共无绳电话系统中,无绳电话手机单元尽可能地请求并建立与期望的本地服务提供商所服务的公共基站的通信链路。 通过生成包含特定载波请求码的服务请求,手机单元选择性地识别由所需本地服务提供商服务的可用的公共基站单元,然后与该基站建立通信链路。 响应于从手机单元接收到服务请求,由所选服务提供商操作的所有公共基站单元通过提供第一确认信号来进行响应。 所有其他公共基站单元通过提供第二确认信号作出响应。 当两个这样的信号被接收时,手机单元仅响应于第一确认信号,并建立与提供该信号的第一基站单元的通信链路。 当仅接收到第二确认信号时,手机单元通过建立与提供该第二确认信号的第一基站单元的通信链路进行响应。 当与提供第二确认信号的基本单元建立通信时,在手机单元处产生报警信号,从而通知用户即使他或她能够进行电话呼叫,也未到达所需的本地服务提供商。 支持该操作的公共基站单元之间的冲突避免可以通过分配多个时间中的特定的一个来提供,在此期间,每个公共基站单元可以响应来自手机单元的服务请求。

    • A reset device is disclosed which may be used in electrical devices such as portable telephones. The reset device includes a source, such as a rechargeable battery, which provides an input voltage and a threshold voltage. The reset device also has a comparator with a first input which receives the input voltage and a second input which receives the threshold voltage. A voltage changing device varies the threshold voltage in response to the output level of the comparator and a rate of increase of the input voltage. The voltage changing device includes a capacitor which delays an increase of the threshold voltage when the input voltage increases. Further, the voltage changing device includes a positive feedback resistor for increasing the threshold voltage when the output level increases. Thus, the positive feedback resistor allows switching the threshold voltage from a first threshold level to a second threshold level when the output level switches from a low level to a high level. The reset device further includes a regulator which regulates the input voltage to provide the threshold voltage. In addition, a switch is connected to an output of the comparator for providing a reset signal to a load. Illustratively, a controller receives the reset signal and resets the load, e.g., the portable phone. In response to the reset signal, the controller switches the portable phone between a dormant mode and an active mode. In addition, the controller allows trickle charging of the rechargeable battery in the dormant mode and rapid charging in the active mode.
    • 公开了可用于诸如便携式电话的电气设备中的复位装置。 复位装置包括提供输入电压和阈值电压的源,例如可充电电池。 复位装置还具有比较器,其具有接收输入电压的第一输入端和接收阈值电压的第二输入端。 电压改变装置响应于比较器的输出电平和输入电压的增加率来改变阈值电压。 电压改变装置包括当输入电压增加时延迟阈值电压的增加的电容器。 此外,电压改变装置包括正反馈电阻器,用于当输出电平增加时增加阈值电压。 因此,正反馈电阻器允许当输出电平从低电平切换到高电平时将阈值电压从第一阈值电平切换到第二阈值电平。 复位装置还包括调节器以调节输入电压以提供阈值电压。 此外,开关连接到比较器的输出,以向负载提供复位信号。 说明性地,控制器接收复位信号并复位负载,例如便携式电话。 响应于复位信号,控制器在休眠模式和活动模式之间切换便携式电话。 此外,控制器允许以休眠模式对可再充电电池进行涓流充电,并且在活动模式下快速充电。

    • In the rapid charging of a Nickel Cadmium (NiCad) battery, the rapid charging is terminated and trickle charging is initiated when any of three conditions is satisfied: a first condition determined by comparing a sensed instantaneous battery voltage with a target voltage; a second condition which is determined by comparing the instantaneous battery temperature with minimum and maximum values; and a third condition determined by comparing an elapsed time of rapid charging with a maximum value. Because battery voltage versus rapid charging time is a function of ambient temperature, the target voltage is determined from an initial measurement of battery temperature, which is assumed to equal the ambient temperature. The target voltage, which is approximately a linearly declining function of ambient temperature, is determined by reading a stored lookup table using the sensed temperature as an index or address.
    • 在镍镉(NiCad)电池的快速充电中,快速充电终止,并且当满足三个条件中的任何一个时开始涓流充电:通过将感测的瞬时电池电压与目标电压进行比较而确定的第一条件; 通过将瞬时电池温度与最小值和最大值进行比较来确定的第二条件; 以及通过将快速充电的经过时间与最大值进行比较而确定的第三条件。 因为电池电压与快速充电时间是环境温度的函数,所以目标电压是从电池温度的初始测量中确定的,这被认为等于环境温度。 通过使用感测的温度读取存储的查找表作为索引或地址来确定近似环境温度的线性下降函数的目标电压。
