    • A method is provided for secure communication between a transmitter and a receiver. The transmitter comprises a non-volatile memory for storing a first portion of a count value, where the count value is updated after an elapse of a period of time. The transmitter comprises a volatile memory for storing a second portion of the count value. In response to receipt of a transmit request, the transmitter sets a use indicator corresponding to the first portion of the count value. Upon elapse of the period of time, the second portion of the count value is updated. The first portion of the count value is updated if the second portion of the count value overflows and if the use indicator corresponding to the first portion set. A message authentication code is generated based on at least the count value. A message transmitted to the receiver comprises at least the message authentication code.
    • 提供了一种用于发射机和接收机之间的安全通信的方法。 发射机包括用于存储计数值的第一部分的非易失性存储器,其中计数值在经过一段时间后被更新。 发射机包括用于存储计数值的第二部分的易失性存储器。 响应于接收到发送请求,发射机设置对应于计数值的第一部分的使用指示符。 经过一段时间后,计数值的第二部分被更新。 如果计数值的第二部分溢出并且与第一部分相对应的使用指示符,则更新计数值的第一部分。 至少基于计数值生成消息认证码。 发送到接收器的消息至少包括消息认证码。

    • This invention relates to a phonics and reading teaching device which depicts an arrangement of indicia representing letters of the alphabet and their associated phonemes. Selection of individual indicia causes the device to generate an audio signal or other response. The audio signal is generated by an output in the form of a speaker, and a processor is provided for controlling the operation of the device. In one mode of operation, the processor causes the speaker to produce a prompting signal indicating a word, and in response to each sequentially correct selection of a letter in the word, to produce a signal representative of a phoneme associated with the letter. The phoneme produced is dependent on the position of the letter in the word. When all of the letters in the word have been selected in correct order, the processor causes the speaker to produce a signal representing a pronunciation of the word or other affirmative acknowledgement. In another mode of operation, the processor operates in a "Make a word" mode. The processor responds to a selection of a letter by causing the speaker to produce a signal representative of the name or phoneme of the letter, and waits for another letter to be selected. After a predetermined number of letters have been selected, the processor causes the speaker to produce a signal representative of phonemes associated with each of the letters and a signal representative of a pronunciation of the sequence of letters.
    • 本发明涉及一种语音和阅读教学装置,其中描述了表示字母表及其相关音素的字母的标记的布置。 个别标记的选择会导致设备产生音频信号或其他响应。 音频信号由扬声器形式的输出产生,并且提供处理器用于控制设备的操作。 在一种操作模式中,处理器使扬声器产生指示单词的提示信号,并且响应于单词中每个顺序正确选择一个字母,以产生表示与该字母相关联的音素的信号。 所产生的音素取决于字母中的位置。 当单词中的所有字母都以正确的顺序被选择时,处理器使扬声器产生表示单词发音或其他肯定确认的信号。 在另一种操作模式下,处理器以“打字”模式运行。 处理器通过使扬声器产生表示字母的名称或音素的信号来响应一个字母的选择,并等待另一个字母被选择。 在选择了预定数量的字母之后,处理器使扬声器产生代表与每个字母相关联的音素的信号和表示字母序列的发音的信号。
