Abstract: A sensor package is disclosed. The sensor package can include a support structure that is configured to couple with a vibration source by way of a stud. The sensor package can include a cap that is at least partially disposed over the support structure. The cap at least partially defines a cavity. The sensor package can include a vibration sensor module that is coupled to a portion of the support structure and disposed in the cavity. The sensor package can have a mechanical resonant frequency in a range of 0.1 Hz to 11 kHz. The sensor package can include a connector that is coupled to the support structure. The connector can connect to a connection line is electrically connect the vibration sensor module to an external substrate or system. The support structure can include a material that has a Young's modulus of at least 60 GPa and a density less than 3000 kg/m3. The sensor package can include a filler material disposed in the cavity.

Abstract: A computer-based method that allows automated measurement of a number of metrics that likely reflect the quality of a colonoscopic procedure. The method is based on analysis of a digitized video file created during colonoscopy, and produces information regarding insertion time, withdrawal time, images at the time of maximal intubation, the time and ratio of clear versus blurred or non-informative images, and a first estimate of effort performed by the endoscopist. As these metrics can be obtained automatically, the method allows future quality control in the day-to-day medical practice setting on a large scale. In addition, the method can be adapted to other healthcare procedures. The method may be useful to assess progress during colonoscopy training, or as part of endoscopic skills assessment evaluations.

Abstract: One embodiment of the present invention provides a system that facilitates web service access to telephony functionality. During operation, the system receives a request at a web service to access the telephony functionality using a Voice Over Internet Protocol (VOIP) network. In response, the system selects an interface to the VOIP network, routes the telephony functionality to a public switched telephone network (PSTN), and accesses the telephony functionality.

Abstract: One embodiment of the present invention provides a system that provides a unified telephony solution. During operation, the system receives a request for a telephony service at a telephony controller. In response to this request, the system accesses a telephony service provided by an application server through a voice extensible markup language (VXML) browser. While performing the telephony service, the system interfaces to a public switched telephone network (PSTN) through a telephony gateway.

Abstract: One embodiment of the present invention provides a system that facilitates developing applications with telephony functionality. The system includes a session initiation protocol (SIP) gateway configured to interface with a public switched telephone network (PSTN). The SIP gateway translates telephone calls from telephones coupled to the PSTN to SIP protocol messages. A SIP server coupled to the SIP gateway accepts these SIP protocol messages and an application server accesses a voice extensible markup language (VXML) page on behalf of the SIP server. A VXML gateway provides access to the VXML page by a users of the telephones.

Abstract: A filter for filtering a fluid, such as lubricating oil for an engine, has a first element for trapping small particles and a second filter element for trapping sludge, the second filter element being stacked on the first filter element. A flow-deflecting element is disposed between the first filter element and second filter element to provide a spinning motion to oil flowing from the second filter element as that oil joins oil which is passed through the first filter element. The spinning motion of the oil from the bypass filter element encourages mixing of the oil from the second filter element with the oil filtered by the first element. A centrifugal separator is disposed in an annular space between the filter elements and filter housing for imparting a rotary motion to the fluid prior to the fluid passing through the filter elements. This removes large particles from the fluid by centrifugal force so that large particles do not add to the contaminant load in the filter elements.

Abstract: A filter cartridge which removes particulate contaminants from liquids includes an annular filter element which, for example, may be a pleated paper filter element, as well as an array of fins which impart a spiral motion to the liquid prior to the liquid passing through the filter element. The spiral motion imparts a centrifugal force to the particulate contaminants causing heavier filter contaminants to move away from the filter media to proximity with the wall of a housing enclosing the filter media and to subsequently accumulate in an axial space disposed beneath the filter media. Since the filter media does not need to remove particles already precipitated out of the liquid, the life of the filter media is extended, the capacity of the filter media is increased, and the distribution of contaminant particles over the upstream side of the filter media is made more uniform.
