    • A messaging system and method are described. The system includes acquisition means for acquiring audio and/or video data, e.g. microphones and cameras. The system further comprises database means (16). In the database (16), sets (32, 34, 36) of situational information (32a, 34a, 36a) and associated messaging information (32b, 34b, 36b) are stored. Processing means try to match the audio/video data to the stored situational information (32a, 34a, 36a). In case a match is found, the associated messaging information (32b, 34b, 36b) is presented using presentation means (18, 75a, 75b). The device and method are thus able to recognize a predefined situation observed by the acquisition means and to present a predetermined message associated with the recognized situation. This can advantageously be employed to present advertising messages adapted to a presently occurring situation.
    • 描述消息系统和方法。 该系统包括用于获取音频和/或视频数据的获取装置,例如, 麦克风和相机。 系统还包括数据库装置(16)。 在数据库(16)中,存储情境信息(32a,34a,36a)和相关联的消息收发信息(32b,34b,36b)的集合(32,34,36)。 处理意味着尝试将音频/视频数据与存储的情境信息(32a,34a,36a)进行匹配。 在找到匹配的情况下,使用呈现装置(18,75a,75b)呈现相关联的消息收发信息(32b,34b,36b)。 因此,该装置和方法能够识别由获取装置观察到的预定义情况,并且呈现与所识别的情况相关联的预定消息。 这可以有利地用于呈现适于当前发生的情况的广告消息。

    • A reduced pin count, dual channel driver interface is configured to interface a supervisory controller with a plurality of multi-phase output channel switching circuits of a multi-phase DC-DC regulator. Each dual channel driver is configured for placement relatively close to output channel sense points, so as to effectively reduce the distance that would otherwise have to be traversed by noise sensitive voltage signals. Sensed current representative signals are processed within the dual driver for current balance between a respective multi driver pair, and are combined to supply the controller with the average current signal of the dual channels. The controller uses this average current-information to adjust respective pulse width modulation signals that are supplied to the dual channel drivers.
    • 减少引脚数,双通道驱动器接口被配置为将监控器与多相DC-DC调节器的多个多相输出通道切换电路接口。 每个双通道驱动器配置为相对靠近输出通道检测点进行放置,以便有效地减少噪声敏感电压信号否则必须穿过的距离。 感测的电流代表信号在双驱动器内处理,用于在相应的多驱动器对之间的电流平衡,并被组合以向控制器提供双通道的平均电流信号。 控制器使用该平均电流信息来调整提供给双通道驱动器的各个脉冲宽度调制信号。
