    • A telephone answering system for providing textual messages and voice messages generated by telephone answering of telephones of persons having telephone calls answered by the system. A system memory stores textual and voice messages. A voice message recording system controls recording of voice messages of answered telephone calls of persons having telephone calls answered by the telephone answering system. A textual message recording system controls recording of textual messages provided by an operator who answers telephone calls made to persons having their telephones answered by the telephone answering system. A programmed computer program implements the voice message recording system and the textual message recording system by execution of a program. The computer decodes a telephone number of each telephone call answered by the telephone answering system, determines a program service option to be performed in answering each telephone call based upon the decoded telephone number, causes the voice message recording system to record a voice message in the system memory if the service option is specified to be answering telephone calls by the voice message recording system, initiates ringing of an operator to cause the operator to answer the telephone call and causes the textual message recording system to record textual messages in the system memory if the service option is specified to use an operator to record textual messages. The recording systems function to permit selective playback of individual recorded messages by the placing of a telephone call to the answering system.
    • 一种电话应答系统,用于提供由系统应答的具有电话的人的电话的电话应答产生的文本消息和语音消息。 系统存储器存储文本和语音消息。 语音消息记录系统控制由电话应答系统应答的具有电话的人的应答电话的语音消息的记录。 文本消息记录系统控制由操作者提供的文本消息的记录,所述操作者回答通过电话应答系统应答的电话的电话。 编程的计算机程序通过执行程序来实现语音消息记录系统和文本消息记录系统。 计算机对由电话应答系统应答的每个电话呼叫的电话号码进行解码,基于解码的电话号码确定应答每个电话呼叫中要执行的节目服务选项,使语音消息记录系统在语音消息中记录语音消息 如果服务选项被指定为通过语音消息记录系统应答电话呼叫,则系统存储器发起操作者的振铃以使操作者应答电话呼叫,并且使得文本消息记录系统将文本消息记录在系统存储器中,如果 指定服务选项以使用运算符记录文本消息。 记录系统的功能是允许通过向应答系统发送电话呼叫来选择性地播放各个记录的消息。

    • Systems and methods for detecting touchdown of a head on a disk are provided. In one embodiment, a disk drive comprises a thermal sensor configured to sense a temperature of a head and to generate a thermal signal based on the sensed temperature. The disk drive also comprises touchdown circuit configured to receive the thermal signal, to increment a count value each time the thermal signal exceeds a thermal threshold, and to output a fault signal when the count value is equal to or exceeds a count threshold.
