A medical ultrasonic diagnostic imaging system is provided which is capable of being accessed over data communication networks such as the Internet, making the ultrasonic images, diagnostic reports, and ultrasound system diagnostics information and operation accessible to a conventional personal computer using commercially available software at virtually any remote location. In one embodiment, the ultrasound system can be remotely operated from the personal computer. The inventive apparatus and techniques make it possible for physicians to remotely access, control, and perform diagnoses using their ultrasound systems over a network such as the World Wide Web with no special hardware requirements.

Ultrasonic diagnostic imaging system with universal access to diagnostic information and images

A monitoring system for a heating, ventilation, and air conditioning (HVAC) system of a building includes a monitoring device installed at the building, a monitoring server located remotely from the building, and a review server. The monitoring device measures an aggregate current supplied to components of the HVAC system and transmits current data based on the measured aggregate current. The monitoring server receives the transmitted current data and, based on the received current data, assesses whether failures have occurred in first and second components of the HVAC components. The monitoring server generates a first advisory in response to determining that the failure has occurred in the first component. The review server provides the first advisory to a technician for review and, in response to the technician verifying that the failure has occurred, transmits a first alert.

Risk-based maintenance—Techniques and applications

A monitoring system for a heating, ventilation, and air conditioning (HVAC) system of a residence includes a monitoring device installed at the residence and a server located remotely from the residence. The monitoring device measures an aggregate current supplied to a plurality of components of the HVAC system and transmits current data based on the measured aggregate current. The server receives the transmitted current data and, based on the received current, assesses whether a failure has occurred in a first component of the plurality of components of the HVAC system and assesses whether a failure has occurred in a second component of the plurality of components of the HVAC system.

Ultrasonic arrays allow a given scatterer to be illuminated from a wide range of angles and hence are capable of extracting significant information about the scatterer. In this paper a general imaging methodology, termed multi-mode total focusing method, is proposed in which any combination of modes and reflections can be used to produce an image of the test structure. Like the total focusing method, this approach is implemented by post-processing the full matrix of array data to achieve a synthetic focus at every pixel in the image. A hybrid model is used to predict the array data and demonstrate the performance of the multi-mode imaging concept. This hybrid model combines far field scattering coefficient matrices with a ray-based wave propagation model. This allows the inclusion of longitudinal waves, shear waves and wave mode conversions. It is shown that, with prior knowledge of likely scatterer location and orientation, the mode combination and array location can be optimised to maximise the performance of array inspections. A practically relevant weld inspection application is then described and its optimisation is discussed.

PURPOSE:To make it possible to closely bring a probe surface into contact with an object to be inspected easily regardless of the configuration thereof, by a method wherein plural ultrasonic vibrator sets are roughly arranged and the spaces between each ultrasonic vibrator sets are respectively connected by connecting materials in a bendable and deformable manner. CONSTITUTION:An array type probe 1 is constituted from N numbers of ultrasonic vibrator sets 2(1)-2(N) arranged in parallel relation to each other and the aforementioned each sets are respectively constituted from M numbers of ultrasonic vibrators 3(1)-3(M). In adition, flexible connecting rods 7 are attached between each ultrasonic vibrator sets 2(1)-2(N). By this connecting rods 7, the distances between each ultrasonic vibrator elements 2(1)-2(N) are kept constant and each ultrasonic vibrator sets are constituted so as to be subjected to free and mutual positional displacement in the arranged direction thereof. By this method, a probe surface can be brought into contact with an object to be inspected closely and easily regardless of the configuration thereof.

Described herein are methods and systems for aligning a wafer using a wafer leveling map with alignment marks. A set of alignment marks can be selected to create overlay correction parameters to realign the wafer. Alignment marks that are near wafer leveling hotspots, or alignment marks that have poor reproducibility are not selected for realignment purposes. The wafer leveling data is used to determine which alignment marks have poor reproducibility and can create an unstable offset. The wafer leveling data identifies areas on the wafer that are uneven. Only alignment marks which have a stable offset are used to calculate the associated overlay correction parameters.
