    • A communication apparatus and a method for supporting carrier sense multiple access/collision detection (CSMA/CD) are disclosed. In a home network having a plurality of peripheral apparatuses in one home bus, the communication apparatus includes an interface circuit for transmitting and receiving packet data by being connected to the home bus; a data transmitting circuit for converting transmission data generated from inner peripheral apparatuses into physical transmission data and then for outputting the data on the home bus through the interface circuit; a data receiving circuit for determining whether data transmitted from other peripheral apparatuses through the interface circuit are received in its own peripheral apparatus and for checking a current state of the home bus; a collision detection circuit for continuously detecting a current state of the home bus through the data receiving circuit; and a communication controlling part for controlling data which are output form the data transmitting circuit by detecting a state of the home bus detected from the collision detection circuit.

    • Methods of detecting a load level in a washing machine include monitoring a rotational speed of a motor of the washing machine for a period of time after the motor has reached an operating speed. In a first method embodying the invention, the number of rotational speed peaks that occur in each of a plurality of speed bands are detected during the period of time. The detected number of speed peaks in each speed band are compared to reference count numbers corresponding to each of the speed bands, and a load level in the washer is determined based on the comparisons. In a second method embodying the invention, the number of times that the rotational speed of the motor exceeds a predetermined speed during a predetermined period of time is detected. The detected number is then compared to reference count numbers, and the load level in the washing machine is determined based on the comparison. This process may be repeated several times if a sensed eccentricity of the washing machine exceeds a predetermined level of eccentricity. If the process is repeated several times, the count value during each repetition may be stored in a different count variable. Then, during one of the repetitions, a sum of two or more count values may be compared to reference count values to determine a load level in the washing machine.
    • 检测洗衣机中的负载水平的方法包括在电动机达到操作速度之后的一段时间内监视洗衣机的电动机的转速。 在实施本发明的第一种方法中,在一段时间内检测出在多个速度带中的每一个中发生的转速峰值的数量。 将检测到的每个速度带中的速度峰值与对应于每个速度带的参考计数进行比较,并且基于比较确定洗衣机中的负载水平。 在实施本发明的第二方法中,检测在预定时间段期间电机的转速超过预定速度的次数。 然后将检测到的数量与参考计数值进行比较,并且基于比较确定洗衣机中的负载水平。 如果感测到的洗衣机的偏心超过预定的偏心水平,则该过程可重复多次。 如果该过程重复多次,则每个重复期间的计数值可以存储在不同的计数变量中。 然后,在重复之一期间,可以将两个或更多个计数值的总和与参考计数值进行比较,以确定洗衣机中的负载水平。
