  • Patent number: 10205914
    Abstract: Systems and methods for streaming video and/or audio from wireless cameras are provided. Methods may include, at a network camera, receiving an instruction to begin video capture from a first network node, including information identifying a second network node. A first video stream may be sent from the network camera to the first network node, and a second video stream may be simultaneously sent to the second network node. The first and second video streams may be based on common video capture data, and may be sent at different bitrates, different resolutions, different frame-rates, and/or different formats. A parameter of the second video stream may be adjusted in response to performance data received from the second network node or another network node.

  • Patent number: 10110855
    Abstract: Systems and methods for connecting wireless cameras are provided. A computing device may include a network interface, and a processor configured to establish a virtual USB bus available to an operating system of the computing device, establish a virtual USB camera device, and report to the operating system that the virtual USB camera device is connected to the virtual USB bus. The virtual USB camera may be configured to establish a network connection to a network camera using the network interface, receive video data from the network camera via the network interface, and send the video data via the virtual USB bus. Alternatively, the virtual USB camera may send the video data to the operating system as USB packets, without establishing a virtual USB bus.

  • Patent number: 9888214
    Abstract: Systems and methods for streaming video and/or audio from multiple devices are provided. A camera may include an optical sensor, a wireless communication device, and a processor configured to establish a first connection with a remote location, establish a second connection with one or more other cameras, and stream video from the cameras to the remote location. The remote location may be, for example, a remote website, a remote server, or a remote client device. The camera may be further configured to provide control signals to the other cameras, such as for controlling applications running on the other cameras.

  • Publication number: 20170170758
    Abstract: A method of determining the parked position of a rotor of a permanent-magnet motor, including applying a first voltage to a phase winding of the motor, measuring a first parameter, removing the first voltage, waiting for current in the phase winding to decrease to zero, applying a second voltage having the opposite polarity, measuring a second parameter, comparing the first parameter and the second parameter, and determining that the rotor is in a first parked position if the first parameter is less than the second parameter, and that the rotor is in a second parked position if the first parameter is greater than the second parameter. The first parameter and the second parameter each correspond to one of (i) the time taken for current in the phase winding to exceed a threshold, and (ii) the magnitude of current in the phase winding at the end of a time interval.

  • Patent number: 9515588
    Abstract: A method of controlling a brushless permanent-magnet motor. The method includes generating a first signal having a voltage that is proportional to a voltage across a winding of the motor, and generating a second signal having a voltage that is proportional to a current in the winding. The second signal is then differentiated to generate a third signal, and the voltages of the first signal and the third signal are compared. An output signal is generated in response to the comparison, the output signal having an edge whenever the voltages of the first signal and the third signal correspond. The winding is then commutated at times relative to the edges in the output signal. Additionally, a control system that implements the method, and a motor system that incorporates the control system.

  • Patent number: 9088235
    Abstract: A method of determining the position of a rotor of a permanent-magnet motor. The method includes sequentially exciting and freewheeling a winding of the motor. The winding is freewheeled for a freewheel period in response to current in the winding exceeding a current limit. The method also includes measuring a parameter that corresponds to either the magnitude of current in the winding at the end of the freewheel period or the interval between the start or end of the freewheel period and the time at which current in the winding exceeds the current limit. The measured parameter is then compared against a threshold and the rotor is determined to be at a predetermined position when the measured parameter is less than or greater than the threshold.

  • Patent number: 9088238
    Abstract: A method of determining the position of a rotor of a permanent-magnet motor. The method uses two different schemes to determine the position of the rotor. A first scheme is used when the rotor rotates within a first speed range, by sequentially exciting and freewheeling a winding of the motor, measuring a parameter that depends on the rate of change of current in the winding, and comparing the parameter against a threshold. A second scheme is used when the rotor rotates within a second speed range, by generating a voltage signal that is proportional to the voltage across the winding, generating a further voltage signal that depends on the rate of change of current in the winding, and comparing the two signals.

  • Patent number: 8606950
    Abstract: A multimedia data processing system and method which transparently processes video and/or audio streams in real-time. The operation of a system in accordance with an embodiment of the present invention does not require any intervention from, or involvement of, either the producer of the video and/or audio stream, or the client application. With such a transparent solution, video and/or audio streams can be processed seamlessly, and completely independently of the specific client application that the user chooses to use. In one embodiment, the invention uses an external service to monitor new processes and add code to these processes. The invention inserts into the system by hot-patching the software in memory and by only looking at select service calls.
