摘要： Disclosed is a device for sensing the opening degree of a valve, which can easily determine the upper and lower limits without using upper and lower limit switches so that, besides simplifying the mechanical structure, the device can be easily installed, maintained, and repaired. The device can avoid basic errors and improve the opening degree sensing performance without using upper and lower limit switches, cams, and a spline so that, by simplifying the mechanical structure, the device can be manufactured, installed, maintained, and repaired at a low cost, and its long-term durability is improved. The device has a main gear adapted to disengage from the meter gear when the main gear is rotated excessively so that any damage to the meter gear and potentiometer, which may occur during installation or use, is prevented.

摘要： An optical network unit for error detection and recovery of an optical module, and a control method thereof are provided. The optical network unit includes a passive optical network medium access control (PON MAC) to output an optical output control signal to activate a laser diode in a time slot allocated to the optical network unit, a monitor photo diode (PD) to sense whether the laser diode outputs an optical signal and generate a feedback signal and an error detection controller to determine whether optical signal output operation is abnormal by comparing the optical output control signal with the feedback optical signal and interrupting power to at least said laser diode when abnormal operation is determined.

摘要： A solution for allowing conditional access to IP-based broadcast services in a passive optical network is disclosed. When a subscriber requests broadcast services by selecting a broadcast channel, an IP set-top converts the request into an IGMP join message and forwards the message to an ONU/ONT, a unit on the subscriber's side. The ONU/ONT delivers the message to an OLT interworking with a router while storing mapping information of the port that received the message and a MAC address of the selected channel. Thereafter, the OLT extracts information on MAC address of the IP set-top box and the requested broadcast data. The OLT compares the extracted information to the subscriber's subscription information and determines whether to provide the requested broadcast services. If the broadcast services may be provided, the broadcast data provided from the broadcast server is transmitted to the IP set-top box via ONU/ONT based on the stored mapping information.

摘要： A height adjustable folding work platform includes two footplates, a footplate folding portion that foldably connects the footplates, two legs, and two leg folding portions, each of which connect the leg to the outer end of the footplate. Each of the legs includes two support legs and a plurality of cross members that connect the support legs. The leg folding portion selectively engages with one of the cross members so that the height of the height adjustable folding work platform is adjusted.
