  • Patent number: 10578457
    Abstract: An onboard robust and stable vision-inertial navigation system that makes an unmanned vehicle autonomous in its navigation capabilities in the absence of external navigation aids like a global positioning system (GPS). The system is robust to the sensor noise properties of the onboard vision and inertial sensors, as well as errors in initial estimates of the position and orientation of the vehicle. The system enables any unmanned vehicle to autonomously navigate an unfamiliar or unknown environment. The system is also stable and robust to uncertainties in the measurement noise and dynamics of the unmanned vehicle, and does not exhibit any instability when sensors are changed or when sensor noise properties change over time.

    Abstract: The present invention relates to a power output discharge circuit including: an output filter module configured to receive and filter an input voltage and to output the filtered output voltage to a load; an output charge module configured to charge the output filter module when a power source module is plugged into a system cabinet; and an output discharge module configured to cooperate with the output charge module to discharge the output filter module when the power source module is pulled out of the system cabinet. With an implementation of the power output discharge circuit according to the invention, whether the power source module is pulled out of the system cabinet can be monitored in real time, and upon detecting the power source module being pulled out of the system cabinet, the output discharge module can be started rapidly, and the voltage across the output port can be lowered below a safety voltage in a very short period of time.

  • Patent number: 9288879
    Abstract: According to one embodiment there is provided a lamp device (1) having a lighting module (3) and two pairs of external connection pins (5aa, 5ab, 5ba, 5bb) for connecting the lamp device to a supply voltage of a lighting fixture. A first terminal of the lighting module is connected to a pin of a first pair of pins by a switch which is closed in response to a voltage difference between both the pins of the first pair of pins and the pins of the second pair of pins exceeding a respective threshold voltage. The lamp is therefore safe to handle even in a condition where one pair of pins is connected and the other is not.

  • Patent number: 9041258
    Abstract: The present invention provides a machine tool making it possible that an operator needs to remove a key member from a predetermined position after an unlock condition of a door is established when a door lock mechanism brings the door into an unlocked state, meanwhile the operator can recognize the necessity of reattaching the key member to the predetermined position when the door lock mechanism brings the door into a locked state. In the machine tool, an interlock mechanism 5a allows a door lock mechanism 8 to bring a door 3 into the unlocked state in a state that the unlock condition of the door 3 is established and when the key member 9 is removed from the predetermined position and, after the door 3 is unlocked, allows the door lock mechanism 8 to bring the door 3 into the locked state only when the key member 9 is attached to the predetermined position in a state that the door closed state detection mechanism 7 detects that the door is located at the predetermined closed position.

  • Publication number: 20150123468
    Abstract: In response to receiving information regarding an unsafe condition from portable electrical energy storage device (e.g., battery) safety sensors, a locking mechanism controller determines whether the battery is in a desired state to, as a safety measure, have the compartment that holds the battery locked and/or to send a signal to reduce or eliminate current draw from the battery. If the locking mechanism controller determines the battery is in the desired state to have the compartment locked, then it sends a signal to a compartment locking mechanism causing the compartment locking mechanism to lock the compartment in which the battery is located to prevent a user from opening the compartment, and thus helps protect the user against the unsafe condition. In some embodiments, the unsafe condition may be a potential or existing catastrophic failure of the battery in the compartment (e.g., a meltdown, explosion or dangerous leak, etc.).

  • Patent number: 8963379
    Abstract: The invention is directed to a touch-sensitive paper shredder control system. The touching feature is implemented through a series of electronic circuits, taking input from a conductive touch panel on the shredder feed throat, processing the signal, and through a motor driving circuit, stopping the mechanical parts of the shredder. The system has a touch detection circuit unit, which contains a bioelectricity controlled switching circuit to sense the conductive touch panel. The bioelectricity controlled switching circuit is configured to trigger a ground switching circuit in the touch detection circuit unit which outputs to a multifunction control circuit unit. The control circuit unit then takes care of the remaining protection issues. The touching device for paper shredders protects humans and other living beings including pets from injuries through automatic and real time monitoring. The complete control process is both safe and sensitive.
