    • A system for detecting the presence, in an audio channel which may contain voice signals, of a tone at a frequency selectable from among a plurality of selectable frequencies. A bandpass filter receives the audio input; its center frequency is selectable in response to a control signal. A first detector circuit provides from the output of the bandpass filter an output signal when a tone containing substantial energy at about said center frequency is input to the filter. A band-stop filter having the same center frequency as the bandpass filter also receives the input audio; a second detector circuit demodulates and thresholds the band-stop filter output. A micro-controller provides the control signal to set the center frequencies of said filters in response to user selection and analyzes the detector circuit output signals and generates an output signal when the output signal from the first detector circuit indicates the presence of a tone for a predetermined time and the output signal from the second detector circuit indicates the lack of presence of substantial energy at frequencies other than the center frequency for the same predetermined time. Optionally, the invention is applied to substitute for the operator a more pleasing signal than a tone at said filter center frequency.
    • 一种用于检测在可以包含语音信号的音频信道中存在以多个可选择频率可选择的频率的音调的系统。 带通滤波器接收音频输入; 其中心频率可响应于控制信号而选择。 当将包含大约中心频率的实质能量的音调输入到滤波器时,第一检测器电路从带通滤波器的输出提供输出信号。 具有与带通滤波器相同的中心频率的带阻滤波器也接收输入音频; 第二检测器电路对带阻滤波器输出进行解调和阈值。 微控制器提供控制信号以响应于用户选择来设置所述滤波器的中心频率,并分析检测器电路输出信号,并且当来自第一检测器电路的输出信号指示存在用于 来自第二检测器电路的输出信号指示在相同的预定时间内,在中心频率以外的频率处缺乏实质的能量。 可选地,本发明被应用于替代操作者比在所述滤波器中心频率处的音调更令人愉快的信号。

    • A toner cartridge having a microcontroller configured to store data necessary to create a message authentication code required by the printer. The microcontroller contains data values capable of generating acceptable MACs for a plurality of printers used in a plurality of geographic regions. The microcontroller recognizes a variety of unique parameters displayed by the printer's processor to identify the geographic region of the printer being used. Once the printer and geographic region are identified, the microcontroller loads the data values associated with the printer and generates an acceptable MAC to enable printer operation.
