Abstract:
System architecture that provides computer-based methods of wireless communication between a wireless metrological device and a mobile computing device that includes the sending/receiving of data (e.g., measurements) along with a universal generic data service that includes data descriptor(s) affiliated with the measurements. The architecture and methods, which may be communicated via BLE, allow for uniform communication between tools and mobile computing devices regardless of tool type, manufacturer, and measurement information.

Abstract:
Systems and methods for managing patient monitoring devices are disclosed. Patient information is transmitted from a patient sensor operatively coupled to a patient to a patient monitor. The patient sensor and the patient monitor are communicatively coupled over a communications network available in a designated monitoring area. Further, loss of the patient sensor from the designated monitoring area is detected by one or more of the patient sensor, the patient monitor and a user. One or more loss prevention indicators are initiated at the patient sensor upon detecting the loss of the patient sensor. Additionally, the loss prevention indicators are communicated to indicate location of the lost patient sensor.
Abstract:
A method for controlling data flow in a wireless body area network includes transmitting sensor data from a plurality of sensor nodes to a gateway via a first transmission channel. The method further includes transmitting beacon data from the gateway to the plurality of sensor nodes via the first transmission channel. The method also includes determining channel packet loss information of the first transmission channel based on at least one of a beacon packet loss information included in the sensor data and a sensor packet loss information included in the beacon data. The method further includes comparing the channel packet loss information with a packet loss threshold. The method also includes switching flow of the sensor data and the beacon data through a second transmission channel instead of the first transmission channel, if the channel packet loss information is greater than the packet loss threshold.
Abstract:
A meteorological system for calibrating a field measurement apparatus includes a field measurement apparatus coupled to a field device. The measurement apparatus is configured to generate measurement signals corresponding to a physical measurement associated with the field device. The measurement signals define a raw data stream. The system also includes a mobile calibration device including a transfer function module with a resident corrective algorithm. The mobile calibration device also includes a calibration standard data module including calibration standard data associated with the measurement apparatus resident thereon. The mobile calibration device is configured to establish bi-directional communication with the measurement apparatus, facilitate shifting the measurement apparatus to a calibration mode, receive the raw data stream from the measurement apparatus, transmit the raw data stream to the transfer function module, and calibrate the field measurement apparatus. The transfer function module is configured to generate a difference data stream through the corrective algorithm.

A remote monitoring system is presented. The system includes a sensor unit disposed in the electrical device, and configured to obtain measurement characteristics in response to a measurand of the electrical device, obtain reference characteristics insensitive to the measurand of the electrical device, and communicate the measurement characteristics and the reference characteristics using time varying electromagnetic fields. Further, the system includes a reader unit to establish a far-field communication with the sensor unit in the presence of at least one metallic interferer in the electrical device, wherein the reader unit is configured to receive the time varying electromagnetic fields associated with the measurement characteristics and the reference characteristics in response to a radio frequency signal transmitted to the sensor unit, and determine the measurand of the electrical device based on at least one property of the received time varying electromagnetic fields associated with the measurement characteristics and the reference characteristics.
Abstract:
The present application provides for feeler gauges. The feeler gauges include a plurality of elongate measuring leaves rotatably coupled on a common axis of rotation with an elongate housing. The leaves may be manually, selectively rotatable between a “home” position wherein the leaves are substantially aligned with the housing and an “extended” position wherein the leaves are spaced from the housing. The leaves may be relatively flexible and substantially flat such that they define a substantially constant thickness. One or more extended leaves may be used to measure the thickness of a clearance or gap. The gauges may be configured to detect, determine or measure the thickness of the leaves that are in the “home” position and/or the “extended” position, and thereby determine the total thickness of a clearance or gap measured by the extended leaves.
