Abstract: Monitoring street lighting infrastructure using special signaling devices and techniques for locating key components of the infrastructure and assessing their status. The integrity of common powerline connections may also be assessed.

Abstract: A system for identifying a fault in a light source is presented. The system includes at least one luminaire that includes the light source configured to emit light. Also, the at least one luminaire includes a monitoring device disposed proximate to the light source. The monitoring device includes a sensing unit configured to measure an amount of light emitted by the light source, and a squawk unit configured to generate a squawk signal based on the amount of light emitted from the light source, where the squawk signal is indicative of the fault in the light source. Further, the system includes a diagnostic unit communicatively coupled to the at least one luminaire and configured to determine the fault in the light source based on the squawk signal, and transmit a termination signal to the squawk unit to decouple an electrical power supply from the light source.

Abstract: A method for generating a sampled plethysmograph data, includes measuring a plethysmograph waveform indicative of a first cardiac cycle and a second cardiac cycle, each cycle including a systolic waveform and a diastolic waveform. The method further includes estimating a first start time and a first duration for the systolic waveform of the first cardiac cycle and computing a plurality of amplitudes at a plurality of time instants for the first duration. The method further includes determining a second start time and a second duration of the systolic waveform of the second cardiac cycle. The method also includes assigning the second cardiac cycle, the second start time, and the second duration to the first cardiac cycle, the first start time, and the first duration respectively. The method further includes iteratively performing the steps of measuring, estimating, computing, determining and assigning for the plurality of cardiac cycles acquired sequentially in time.

Abstract: Systems and methods for communicating ultrasound probe location and image information are provided. One system includes an ultrasound device coupled with an ultrasound probe and configured to acquire ultrasound images of a subject. The ultrasound imaging system also includes at least one camera configured to acquire (i) scene information including ultrasound imagery of the ultrasound probe with the subject during an image scan and (ii) ancillary probe data. The ultrasound imaging system further includes a processor configured to receive the ultrasound images and the ancillary probe data and a multiplexing unit configured to receive (i) the ultrasound images and ancillary probe data from the processor and (ii) the scene information from the camera, wherein the multiplexing unit is further configured to associate in time the ultrasound images, ancillary probe data and scene information. The ultrasound imaging system additionally includes a communication device.

Abstract: Systems and methods for providing ultrasound probe location and image information are provided. One system includes an ultrasound device coupled with an ultrasound probe and configured to acquire ultrasound images of a subject. The system further includes at least one of a plurality of digital cameras or a plurality of digital scanners configured to acquire scene information including images of the ultrasound probe with the subject during an image scan. The system also includes a processor having an ultrasound registration unit (URU) with the URU configured to identify and reference a probe location of the ultrasound probe to a surface of the object from the scene information and correlate the probe location to one or more of the acquired ultrasound images. The URU is additionally configured to generate a representation of the surface showing the identified and referenced probe location corresponding to the correlated ultrasound images.

Abstract: Systems and methods for communicating ultrasound data are provided. One method includes monitoring over time estimates of bandwidth of a channel communicatively coupling an imaging location with another location remote from the imaging location and communicating the estimates to a system at the imaging location. The method also includes identifying at least one of a region-of-interest (ROI) mask or one or more transmission parameters for the channel and adjusting at least one of the ROI mask or the one or more transmission parameters based on the monitored estimates of the bandwidth for communicating the medical images.
