  • Patent number: 10263422
    Abstract: A shutdown controlling method is applied to a system that has a host computer, a PDU and multiple electric apparatus connected to the PDU. The PDU has multiple outlets and stores preset shutdown periods for the outlets respectively. The PDU communicates with the electric apparatus and obtains their required shutdown periods. When PDU is controlled to cut off an outlet, the PDU determines whether the preset shutdown period of the outlet is larger than the required shutdown period. If yes, the PDU cuts out the AC power of the outlet. If not, the PDU cancels the shutdown command and notifies the host computer. Therefore, a manager may update the preset shutdown period of the outlet to ensure that each electric apparatus has enough time to be safely shut down.

  • Patent number: 9929592
    Abstract: A UPS sensitivity of power status parameter adjustment setting method used in UPS system for allowing sensitivity setting of power status parameter manually by user or according to system default value. Microcontroller can automatically switch sensitivity to HIGH to enhance power protection if power status of input power supply is judged in the range set according to option of energy-saving, electrical safety or set time in priority after completing counting time. If power generator of relatively lower power quality level is used for input power supply, microcontroller can automatically switch sensitivity to LOW subject to option of energy-saving in priority and employ a low-sensitivity detection of power judgment, maintaining USP system in normal mode without being changed to battery mode, preventing system shutdown due to complete discharge of stored energy systems, and UPS system can operate normally, and power supply of stored energy systems can be prolonged and well-protected.

  • Patent number: 8897896
    Abstract: A controlling system has a computer having a controlling interface, a PDU linking to the computer and multiple electric apparatus connected and linking to the PDU and the computer. The PDU has multiple outlets, a turn-off time for each outlet. The controlling interface of the computer presets that the turn-off time for each outlet and has a shut-down option. The shut-down option has outlet numbers, a main time axis, and multiple variable time axes. Each variable time axis has a start time and an end time. A total period of each variable time axis between the start time and the end time is determined according to the shut-down period of the corresponding electric apparatus. The start time and the end time of each variable time axis are adjustable, but the total time thereof is fixed. Once the start times and the end times are determined finally, the turn-off times for the outlet numbers are calculated and further sent to the PDU.

  • Patent number: 8868937
    Abstract: A method of remotely controlling power distribution units enables the power distribution units to automatically transmit messages to a server once connected to the server via a network. When a user logs into a server and requests to remotely control the associated power distribution units, the user only needs to enter the serial numbers or identification data thereof. The server then automatically searches for all power distribution units owned by the user, and provides a group management interface. The user can then group the power distribution units according to their locations or their properties in order to control the on and off thereof. Without knowing the IP addresses of the power distribution units, the user can readily control the power distribution units at different locations remotely.

  • Publication number: 20130226363
    Abstract: A shut-down controlling system for power distribution unit (PDU) has a computer a PDU and multiple electric apparatus connected to the PDU. The PDU has multiple outlets and stores a shut-down controlling procedure and a shut-down period for each of the outlet. The PDU automatically communicates with the electric apparatus and obtains the actual shut-down period of the present electric apparatus. The PDU further determines whether the preset shut-down period is larger than the actual shut-down. If yes, the PDU cuts out the AC power source of the selected outlet when the preset shut-down period is achieved. If not, the PDU cancels the shut-down command and notifies the computer. Therefore, a manager will resets the shut-down period of the selected outlet to ensure that each electric apparatus has enough time to complete the shut-down procedure.

  • Patent number: 8390721
    Abstract: The present invention provides a camera module for a portable electronic device. A beam splitter has a first light input end for receiving a first light beam, a second light input end for receiving a second light beam and a light output end for outputting the first or second light beams that enter from the first and second light input ends respectively. A reflector is positioned at the upstream of the first light input end of the beam splitter to redirect the first light beam to the first light input end of the beam splitter. An image sensor is positioned at the downstream of the light output end of the beam splitter to convert the first or second light beams outputted from the light output end into a corresponding signal.

  • Publication number: 20130046410
    Abstract: A method for creating virtual environmental sensor on a power distribution unit is executed by a power distribution unit and has steps of connecting to a network and at least one power-consuming device, searching all environmental sensors through the network, receiving environmental condition messages sent from each environmental sensor, presenting at least one environmental condition range to determine if the environmental condition messages sent from each environmental sensor are out of one of the at least one environmental condition range, and powering on or off a corresponding power-consuming device when each environmental condition message is out of a corresponding environmental condition range. Using the method can create remote environmental sensors networked with the PDU and solve the expansion restriction, spatial limitation and intractable wiring arising from the environmental sensor embedded in the conventional PDU in the form of hardware.

  • Publication number: 20120246492
    Abstract: A remote power group distribution control system has a host computer, at least one network server and multiple power distribution units (PDUs) connected to the host computer through the at least one network server. The host computer has a power distribution control module. Each PDU is connected with multiple power consuming equipment having identical or similar characteristics to supply an operating power and an uninterruptible power. When the power distribution control module is executed, the host computer searches the PDUs connected thereto through the at least one network server, displays all power-consuming equipment connected to each PDU, generates a group management window to assign each power-consuming equipment to a group, and remotely controls the power consuming equipment on a group basis. Accordingly, the present invention addresses a solution conveniently powering on or off remote power-consuming equipment pertaining to a group.
