    • A test sample card is provided with a locking feature for achieving a positive, locking engagement with a transfer tube that conducts fluid into the interior of the test sample card. The locking feature consists of a tubular channel inwardly disposed from the fluid intake port that has an inner annular rim defining a restriction. The annular rim is of a reduced diameter relative to the diameter of the transfer tube. A recessed region is positioned inwardly from the restriction that has an opening in one of the surfaces of the card body. When the transfer tube is inserted into the tubular channel, the first end is forced past the restriction into the recessed region, with the annular rim compressing the transfer tube. The user is able to sense with their hands when the first end is inserted past the restriction. Visual observation of the first end of the transfer tube through the opening in the card surface confirms that the transfer tube has been properly inserted into the test sample card.
    • 测试样品卡具有锁定特征,用于实现与将流体导入测试样品卡内部的传送管的正向锁定接合。 锁定特征包括从流体入口端向内设置的管状通道,其具有限定限制的内部环形边缘。 环形边缘相对于传送管的直径具有减小的直径。 凹陷区域从在卡体的一个表面中具有开口的限制向内定位。 当输送管插入管状通道中时,第一端被迫通过限制器进入凹入区域,其中环形边缘压缩传送管。 当第一端插入超过限制时,用户能够用双手感觉。 通过卡片表面中的开口目视观察转印管的第一端,确认转印管已正确插入测试样品卡中。

    • A method and simultaneous voice/data transmission of signals through a single communications channel wherein the transmitted voice and data signal quality is greatly enhanced over current practice. A time-varying stream of coded voice and data signals is simultaneously transmitted and the sequence of transmitted data signals is determined only after receiving data signals for a predetermined period of time. The received signals are buffered and a received coded data signal sequence is compared to a predetermined plurality of permissible coded data signal sequences to correlate the received coded data signal sequence with the particular permissible coded signal sequence with which the data signal was coded prior to transmission. The correlated data signal sequence is then separated from the combined voice and data signal to recover the coded voice signal. The recovered voice signal and correlated data signal sequence are thereafter decoded to recover the voice and data signals that were received and coded by the transmitter. Timing and equalization of the receiver are also maintained during intervals in which no data signals are transmitted, i.e. "voice only" mode, by generating in such intervals a data tracking signal for combination with the coded voice signal and transmission of the resulting combined signal to the receiver.
    • 通过单个通信信道的方法和信号的同时语音/数据传输,其中传输的语音和数据信号质量比当前实践大大增强。 同时发送编码语音和数据信号的随时间变化的流,并且仅在接收到数据信号一段预定时间后确定所发送的数据信号的序列。 所接收的信号被缓冲,并将接收到的编码数据信号序列与预定的多个允许的编码数据信号序列进行比较,以将接收到的编码数据信号序列与在发送之前对数据信号进行编码的特定允许编码信号序列进行相关。 然后将相关的数据信号序列与组合的语音和数据信号分离,以恢复编码的语音信号。 然后,恢复的语音信号和相关数据信号序列被解码,以恢复由发送器接收和编码的语音和数据信号。 在没有数据信号发送的间隔(即“仅话音”)模式中,通过在这样的间隔中产生与编码的语音信号组合的数据跟踪信号并将所得到的组合信号传输到 收件人。
