Abstract: Provided herein are systems and methods for transmitting medical imaging data across a transmission channel that may be bandwidth constrained. In one or more examples, the system and methods can include transmitting the medical imaging data across a channel using a first specification, and then changing the specification in response to a detected reduction in the available bandwidth of the channel. In one or more examples, the second specification can be based on the type of video data being transmitted. In one or more examples, the medical video data can be apportioned into a region of interest and a region of non-interest, and each region can be transmitted across the channel based on the available bandwidth of the channel.

Abstract: Disclosed herein are systems and methods for powering light sources to reduce optical and/or electrical interference between the light sources and optical components in the same environment. The light sources may be powered using power modulation signals, whose frequency may be varied across modulation periods. Optionally, the frequency may be varied randomly or pseudo randomly. The systems and methods may additionally or alternatively introduce phase modulation into the control signals for driving channels of light sources. A phase difference in the control signals to at least two channels can reduce or avoid simultaneous or synchronous driving of the channels. The systems and methods described herein can vary one or more properties (e.g., frequency, phase shift, delay, duty cycle, power, etc.) of the power modulation signals.

Abstract: A lighting device and system for illuminating the interior of a vehicle, aircraft or building is provided. The lighting device and system includes a channel case made from a thermally conductive material, including aluminum. The channel case has a bottom edge and two opposed side edges forming an interior space. A circuit board is disposed within the interior space of the channel case and the circuit board includes circuit traces on the top, bottom or both sides of the circuit board. A heat transfer device is attached to the bottom of the circuit board and is further attached to the bottom of the channel case. A plurality of light-emitting diodes and resistors are mounted on the circuit board in series and generate light through a lens which is attached to the two opposed side edges of the channel case.
