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:
A system includes wireless sensor devices monitoring a patient, a gateway device providing dual-frequency adaptive protocol time synchronization signals to the sensor devices, the time synchronization signals including a communication frame structure having time slots including two beacon signal time slots and a plurality of data slots, where the sensor devices transmit respective patient data a first time interleaved within a first data slot and a second time interleaved within a second data slot, the first interleaved data transmission and the second interleaved data transmission are each transmitted at respective different frequencies provided to the sensor devices in beacon signals received from the gateway device. The first interleaved data transmission includes both current data and previous data from the at least two wireless sensor devices, and a frequency agility pattern separates adjacent channels by a respective predetermined frequency offset. A method and non-transitory medium are disclosed.
Abstract:
A system and method for a lighting control system to control street lighting fixtures using modified geometric harmonic modulation for communications over a powerline. At least some of the lighting fixtures have another communications capability that enables RF communications. The communications may by messages be sent to the lighting fixtures to read RF enabled meters.
Abstract:
A patient monitoring system includes at least two wireless sensing devices, each configured to measure a different physiological parameter from a patient and wirelessly transmit a parameter dataset. The system further includes a receiver that receives each parameter dataset, a processor, and a monitoring regulation module executable on the processor to assign one of the at least two wireless sensing devices as a dominant wireless sensing device and at least one of the remaining wireless sensing devices as a subordinate wireless sensing device. The physiological parameter measured by the dominant wireless sensing device is a key parameter and the parameter dataset transmitted by the dominant wireless sensing device is a key parameter dataset. The key parameter dataset from the dominant wireless sensing device is processed to determine a stability indicator. The subordinate wireless sensing device is then operated based on the stability indicator for the key parameter.
Abstract:
A system, includes a wireless communication network that transmits data over available radio frequency channels, one or more medical sensors that are associated with a patient and that detect physiological data from the patient, and one or more communication hubs associated with the patient and that receive the detected physiological data from the one or more medical sensors and scan the available radio frequency channels around the one or more communication hubs to generate radio frequency data indicative of a measured signal strength in each available radio frequency channel of the of available radio frequency channels. The one or more communication hubs wirelessly transmit the physiological data and the radio frequency data via one or more of the of available radio frequency channels. The system further includes a processor and a memory storing instructions, such that the instruction cause the processor to receive the radio frequency data and provide communications instructions to the one or more communication hubs to communicate the physiological data over a different available radio frequency channel based on the radio frequency data.
Abstract:
A method for navigating within a retail establishment includes: generating and distributing an encoded identity to each of a plurality of location beacons, the encoded identity being effective during a time interval; broadcasting the encoded identity from each of the plurality of location beacons to a user device within a retail establishment; mapping the encoded identity of each of the plurality of location beacons to a location thereof; generating a masked mapping by combining the mapping with a time interval mask; storing the masked mapping in a website accessible to the user device; and broadcasting an srw signal to the user device within the retail establishment, the srw signal comprising information for recovering the mapping from the masked mapping in the web site; whereby navigation via the location beacons is enabled.
