  • Publication number: 20240139944
    Abstract: The robotic arm operating system includes a control device, a plurality of joint devices and a brake release monitoring device. The control device is used to generate an operation instruction. The joint device is coupled to the control device. Each joint device includes a motor and a driver. The drivers of the joint devices receive the operation instruction to generate corresponding multiple unlocking signals. The unlocking signals are used to release a braking state of the motors of the corresponding joint devices. The brake release monitoring device is coupled to the control device and the joint devices, and includes a plurality of monitoring circuits. When one of the plurality of monitoring circuits does not receive the corresponding unlocking signal, the brake release monitoring device notifies the control device that the operation instruction is not allowed.

  • Patent number: 9208017
    Abstract: A method for protecting against fan failure in a server uses a storage unit and a plurality of fans in the server. The method includes the following steps. A rotation speed of each of the plurality of fans is detected. A continuous working time period of each fan is timed. The rotation speed reading and the continuous working time period reading of each fan is compared with predefined rotation speed values and predefined continuous working time periods stored in the storage unit. The results of comparisons are made. A countdown is started when any of the results of comparison falls into one of predefined failure conditions for the fans. Unless a renew or other countdown-amending signal is received, the server is counted down to zero and then shut down. A server equipped to be able to carry out the protecting method is also provided.

  • Patent number: 8643512
    Abstract: An electronic device and method for managing bus services includes a determination of a target bus route according to destination information input by a passenger, and a generation of riding information. A bus of the target bus route approaching a current bus stop where the passenger is located is determined to be a target bus. The riding information is sent to the target bus, and carrying information is received from the target bus. If the target bus has available passenger capacity to carry the passenger, a request message is sent to the target bus, to request a driver of the target bus to stop at the current bus stop. A notification is outputted to notify the passenger that the target bus is approaching the current bus stop.

  • Patent number: 8612736
    Abstract: A control apparatus includes a power supply unit, a power on unit, a control chip, a baseboard management controller (BMC) chip, and a south bridge. The power on unit sends a first power on signal to the control chip. The control chip receives the first power on signal and sends a triggering signal to the BMC chip. The south bridge is connected to the control chip and the BMC chip. The south bridge is driven to control the power supply unit to power on the computer by the control chip or the BMC chip according to states of the BMC chip after a predetermined time. If the BMC chip is in a start mode, the control chip drives the south bridge; if the BMC chip is in a working mode, the BMC chip receives the triggering signal and drives the south bridge.
