  • Patent number: 8368520
    Abstract: The present invention is to provide a notification system for timed power supply, which includes a timed power supply device and a wireless notification device. The timed power supply device is able to receive a set time inputted by a user and stores the set time into a memory module, and then starts timing, providing power supply and generating an elapsed time, respectively. When the timed power supply device determines that the difference between the elapsed time and the set time reaches a threshold value, the timed power supply device issues a notification signal through a wireless transmitter module to the wireless notification device carried by the user, so as to ensure that the user will be notified, via an alert signal generated by the wireless notification device according to the notification signal, that the set time is coming to an end.

  • Patent number: 7104673
    Abstract: The present invention is to provide a clamp lamp comprising a first side plate, a second side plate and a lateral plate, wherein the lateral plate connects the first side plate and the second side plate, thereby forming a retaining space between the first side plate and the second side plate. A lamp is disposed on the first side plate opposite to the second side plate and powered by at least a battery installed in a battery holder formed on the clamp. A light source can thus be generated from a light emitting portion of the lamp. A screw rod is disposed on the second side plate and connected with a mobile portion. By adjusting the amount of the screw rod inserted into the retaining space, the clamp can firmly grab an object, so as to securely fasten the lamp onto the object.
