Abstract: The disclosure provides a power management method. The power management method is applicable to an electronic device. The electronic device is electrically coupled to an adapter, and includes a system and a battery. The adapter has a feed power. The battery has a discharge power. The power management method of the disclosure includes: reading a power value of the battery; determining a state of the system; and discharging power to the system, when the system is in a power-on state and the power value is greater than a charging stopping value, by using the battery, and controlling, according to the discharge power and the feed power, the adapter to selectively supply power to the system. The disclosure further provides an electronic device using the power management method.

Abstract: Techniques for broadcasting notifications with low latency are provided. A set of recipients for a notification of a content item is determined. The notification is stored in a second notifications storage that is separate from a first notifications storage. A request for one or more notifications is received over a computer network from a client device that is associated with a particular recipient in the set of recipients. In response to receiving the request, first notification data is retrieved from the first notifications storage, second notification data that includes the notification is retrieved from the second notifications storage. The first notification data is combined with the second notification data to generate combined notification data. The combined notification data is transmitted over the computer network to the client device and is stored in the first notifications storage. The notification may be removed from the first notifications storage.

Abstract: A multi-handset cordless telephone system with power backup function causes that the power stored in the handsets can be reused as a power supply of the base unit in power outage state so that the power supply to the base unit is uninterrupted. Furthermore, the rechargeable backup cell added to the circuit further causes that the power is indeed uninterrupted even at the initial timing of the power outage. Moreover, broadcasting to the handsets wirelessly or through networks cause the users to keep attention to the power outage state as it occurs so as to adapt required operations for continuation of communication. However the present invention is suitable for usages of hospitals, hotels, and those having a large amount of handsets distributed in wide areas. These applications need to assure the un-interruption of communication.

Abstract: The present invention is to provide a cup comprising a cup body and a copy base. The cup base includes a circuit portion and a light emitting portion. The circuit portion controls the light emitting portion and provides the light emitting portion the power source needed, so as to project out light source from the light emitting portion. Therefore, the cup of the present invention can produce light source by employing the light emitting portion. In addition, since the cup body is detachably connected with the cup base, the cup is then able to be cleaned and transported more easily.

Abstract: The present invention is to provide a light-emitting device comprising a hollow body having a base, a first and a second light sources on the base, at least one optical fiber section provided on the body, a frame element provided on the body and a foggy and color-changing ball supported on the frame element, wherein the activated first and second light sources are able to emit light to the optical fiber section and the foggy and color-changing ball respectively such that a plurality of optical fibers as the constituent components of the optical fiber section are able to transmit light to the body after collecting the light, and the foggy and color-changing ball is adapted to show a foggy and color-changing effect in addition to the light-emitting effect.

Abstract: A color separation disc assembly combinable with an article formed of optical fibers. The assembly has a color separation disc that is able to rotate along with a shaft of a motor for generating different colors on ends of optical fibers by separating light emitted from a light source therethrough. A lightning ball is adjacent to the article and electrically connected to a high voltage generation circuit for generating lightning therein, enabling the article to have a colorful appearance within a dazzling environment.
