    • An electrical control system is disclosed for controlling a plurality of variable transmittance windows. The electrical control system comprises a master control circuit and user input circuits for supplying control signals representing transmittance levels for the variable transmission windows, and a plurality of slave window control circuits coupled to the master control circuit, user input circuits and the variable transmittance windows. Each slave window control circuit controls the transmittance of at least one of the variable transmission windows in response to control signals received from the master control circuit and/or user input circuits. Also disclosed are novel methods for the manufacture of an electrochromic device used in variable transmittance windows. Novel structural features for improving heat transfer away from the windows, shielding the window from external loads, and improving the electrical performance of the windows are also disclosed.

    • A multi-line key telephone system not having a key service unit includes three analog telephone lines to which up to eight, three-line telephones may be connected to provide enhanced service features with cost-effectiveness. System reliability is maintained, notwithstanding the power dependency of the telephones, by including POTS telephones to provide uninterrupted essential telephone service in the event of a power outage. Both data and voice communications between two or more of the three-line telephones is achieved by converting an input digital bit stream from either a digital or analog source into a corresponding out-of-band binary FSK radio frequency output signal that is transceivingly communicated between the three-line telephones as data packets within a TDM frame. The out-of-band signal thus permits analog voice communications on the same line to proceed without interference. A telephone initiating a communications session acts as a master station, establishing inter-station communications synchronous at the frame level and asynchronous at the packet level. The called telephone functions as a slave station in a second time slot synchronized to a first time slot in the TDM frame received from the master. Temporary storage of data in firmware buffers and controlled timing at both the master and slave permits these stations to function within their respective TDM frame time slots.
    • 没有密钥服务单元的多线密钥电话系统包括三个模拟电话线,多达八个三线电话可以被连接到,以提供具有成本效益的增强的服务特征。 通过在停电的情况下,通过包括POTS电话来提供不间断的基本电话服务,尽管电话机的功率依赖性仍保持系统的可靠性。 通过将来自数字或模拟源的输入数字比特流转换成相应的带外二进制FSK射频输出信号来实现三线电话中的两个或更多个之间的数据和语音通信, 三线电话作为TDM帧内的数据分组。 因此,带外信号允许同一线路上的模拟语音通信不受干扰地进行。 发起通信会话的电话充当主站,在帧级别建立同步的站间通信,在报文级别进行异步。 被叫电话在与从主设备接收的TDM帧中的第一时隙同步的第二时隙中用作从属站。 固件缓冲区中的数据临时存储和主机和从机的受控定时允许这些站在各自的TDM帧时隙内工作。
