摘要： A synchronous audio playback method, apparatus and system are provided. The method includes calculating a first playback delay generated when an audio file is played; acquiring a second playback delay; calculating a delay offset; calculating a data adjustment amount; adding to-be-adjusted data to or deleting to-be-adjusted data from a current to-be-played part of the audio file according to a value of the delay offset, to obtain a replacement part corresponding to the current to-be-played part, where a data amount of the to-be-adjusted data is the data adjustment amount; and playing the replacement part. With the technical solutions of the present invention, playback duration of a current to-be-played part can be adjusted in a manner of adding or deleting data, so that a controlling device and a controlled device generate sounds simultaneously when playing a to-be-played clip in a very simple implementation process.

摘要： Power is supplied to telecom equipment in DSLAM outdoor/remote cabinets with relatively short distances between the subscriber and the cabinet. All of the subscriber Customer Premises Equipment connected to the DSLAM each provide a portion of the required power to the remote cabinet via the telephone line connecting the DSLAM and the subscriber CPE. The CPE at the subscriber premises is already connected to power mains in the subscriber premises so, providing power, via the telephone line to the outdoor cabinet is relatively simple. The remote cabinet includes a circuit for receiving the power input from each subscriber and then distributing the power, required by the DSLAM load, equally among the subscribers.

摘要： An electrically powered node of a telecommunications system has a battery power backup associated with its power control unit. Under normal conditions it is maintained fully charged by means of trickle currents from the mains power feeds to each of a number of mains—connected customer equipments, by way of the “final drop” to the distribution point. These trickle currents are controlled by the respective power control units, to prevent overcharging. Using an electrical copper connection provided in parallel with the fibre connection, a battery backup can also be maintained in nodes further towards the exchange. The feeds are reversible, so that if a power outage removes the power supply from the customer premises, a “lifeline” plain telephone service between the exchange and the telephone handset is maintained using the local battery backup in the remote nodes. By limiting the service to simple telephony, the battery power can be sufficient to maintain the service for a reasonable duration. The power management systems can be used to transfer charge from one battery to another over the network according to the usage, or remaining life, of each battery.
摘要翻译：电信系统的电力节点具有与其功率控制单元相关联的电池电力备份。在正常情况下，通过从主电源馈送到多个电源连接的客户设备中的每一个的涓流来维持完全充电，通过“最终下降”到分配点。这些涓流由各个功率控制单元控制，以防止过充电。使用与光纤连接并联提供的电铜连接，电池备份也可以在进一步朝向交换机的节点中保持。馈电是可逆的，因此如果停电从客户住宅中消除电源，则使用远程节点中的本地电池备份来维护交换机和电话听筒之间的“救生线”普通电话服务。通过将服务限制为简单的电话，电池电量可以足以在合理的持续时间内维护服务。根据每个电池的使用或剩余寿命，电源管理系统可用于通过网络将电荷从一个电池传输到另一个电池。

摘要： A mobile power device includes a mobile power source and a border casing. The mobile power source includes a housing, and the housing has a top plate and an annular plate. The border casing encloses the annular plate. An inner circumference of the border casing has a surrounding block surroundingly disposed around the top plate. The surrounding block protrudes beyond the top plate, and a gap is formed between the surrounding block and the top plate. Therefore, the surrounding block can restrict a position of a portable electronic product, so that the portable electronic product is securely disposed corresponding to the mobile power source to enhance the convenience in using the mobile power device.
