    • A receiver is provided, which is adapted to receive MPE-FEC frames and to correct erroneous sections within a received MPE-FEC frame by detecting unreliable sections and storing in an erasure list (“ESL”) table compressed data that includes the base address of each detected erroneous section, together with the respective section's size. The size of the ESL table may be fixed, or it may correlate, or dynamically change according to the actual number of detected erroneous sections. The data stored in the erasure list may then be forwarded to a decoder to correct erroneous sections. The erroneous sections may be detected by using CRC, and the decoder may be a Reed-Solomon decoder. If the application data table of the MPE-FEC is error-free (or full or errors), in which case the erasure structure list is empty (or full of errors), in which case the erasure structure list is empty (or full), this means that no FEC reception and error corrections are required, because there are no sections to correct in the first case and the decoder is incapable of correcting too many sections in the second case. Therefore, the receiving circuitry, or at least the decoder, may be disabled to save battery power.

    • A digital input device for entering data into a digital system, comprises at least two remote sensors and a control unit. A working area is set up in proximity to the sensors and the position of an object within the working area is detected by the input device based on data provided by each sensor and transmitted, by said control unit, to said digital system. The position of an object outside said working area, if detected by said input device, is rejected by said control unit and is not transmitted to said digital system. The sensors can be ultrasonic sensors and the object can be a part of the body of a user. Use of a third sensor allows three-dimensional detection of the object.
    • 用于将数据输入数字系统的数字输入设备包括至少两个远程传感器和控制单元。 工作区域设置在传感器附近,并且基于由每个传感器提供的数据由输入设备检测到工作区域内的对象的位置,并由所述控制单元发送到所述数字系统。 如果由所述输入装置检测到,所述工作区域外的物体的位置被所述控制单元拒绝,并且不被发送到所述数字系统。 传感器可以是超声波传感器,物体可以是使用者身体的一部分。 使用第三个传感器可以对物体进行三维检测。
