  • Publication number: 20210051035
    Abstract: Embodiments of the disclosure provided herein can be used to improve the control, selection and transmission of data to a remote video conferencing environment, by use of a plurality of wired or wirelessly connected electronic devices. In one example, the transmission of data from a local environment can be improved by switching the source of visual inputs (e.g., cameras or display of an electronic device, such as laptop) and/or audio inputs (e.g., microphones) to the one or more appropriate visual and audio sources available within the local environment. The most appropriate visual and audio sources can be the sources that provide the participants in the remote environment the most relevant data giving the remote users the best understanding of the current activities in the local environment.

  • Publication number: 20200352004
    Abstract: The present disclosure provides an intelligent lighting control system. A controller of the lighting control system causes a phase change cut to be applied to an AC power signal to signal to a light bulb apparatus connected to a luminaire a request to self identify. The encoded phase changed AC power signal is transmitted to the light bulb apparatus for a predetermined time period. A response signal received from the light bulb in response to receipt of the encoded phase changed AC power signal by the light bulb is detected at the lighting control system. A bulb identification is determined based on the response signal from the light bulb apparatus.

  • Publication number: 20200323059
    Abstract: The present disclosure provides intelligent lighting control systems. The light control systems include light bulb apparatuses including a receiver for receiving an encoded alternating current (AC) power signal transmitted from a lighting control system to a luminaire electrically coupled to the light bulb apparatuses, a signal transformer for converting an input signal, a light emitting element coupled to the signal transformer, and a controller communicably coupled to the signal transformer.

  • Patent number: 8432483
    Abstract: A method that includes determining that a device mount power supply included within a device mount is compatible with an electronic device power supply included in an electronic device. The method further includes receiving power transferred from the device mount power supply via a power connection that is provided by a device mounting adapter that is affixed to the device mount and configured to couple the electronic device and the device mount and align the electronic device and the device mount to facilitate charging the electronic device power supply; and charging the electronic device power supply with power received from the device mount power supply via the power connection.

  • Patent number: 8259221
    Abstract: One embodiment of the present invention sets forth a digital camera configured to be powered by rechargeable nickel-metal hydride (NiMH) batteries. The digital camera includes one or more rechargeable NiMH batteries, and first internal circuitry configured to receive power from a universal serial bus (USB) port associated with an external power source and to charge the rechargeable NiMH batteries without removing the rechargeable NiMH batteries from the digital camera.

  • Publication number: 20120069143
    Abstract: A technique for tracking and highlighting an object in stereoscopic images by changing the depth of the object is disclosed. A stereoscopic image is processed using an object detection algorithm to select the pixels associated with the object in the image. The depth of the object is adjusted in the stereoscopic image by adjusting the disparity between the pixels associated with the object in the left and right stereoscopic image pair. The processed stereoscopic image is then displayed on a stereoscopic display or stored in memory. An object is tracked by highlighting the object in consecutive stereoscopic images that depict the object.

  • Publication number: 20120013293
    Abstract: A method that includes determining that a device mount power supply included within a device mount is compatible with an electronic device power supply included in an electronic device. The method further includes receiving power transferred from the device mount power supply via an inductive power connection that is disposed on the device mount at a location other than where a device mounting adapter that is affixed to the device mount is disposed on the device mount, where the device mount adapter is configured to couple the electronic device to the device mount and align the electronic device and the device mount to facilitate charging the electronic device power supply; and charging the electronic device power supply with power received from the device mount power supply via the inductive power connection.
