Abstract: In an integrated optical device, squeezed light is used internally to effectively increase an optical modulation effect. One exemplary device operates by squeezing the light at the input, then sending it through an electro-optic stage where its phase picks up the signal of interest, and finally anti-squeezing it to obtain a displaced coherent state. Thus the displacement is amplified by the level of squeezing that is achieved inside the device and it is thereby less sensitive to loss. Since this device behaves simply as an electro-optic modulator, albeit one with an exponentially enhanced sensitivity, no extra considerations are needed to integrate the modulator into a system. Such devices can be operated as modulators or as sensors, and can make use of optical phase shift effects other than the electro-optic effect.

Abstract: This provides locations for mounting controllers and processing components that effectively employ the roof within a frame covered by a cowling so as to avoid exposure to weather and the environment. The roof is also employed to provide a sensor bar that extends across the vehicle width for a distance that does not interfere with normal vehicle function or generate potential overhangs, which can inadvertently engage objects or vehicles. The bar is sufficient in size and shape so as to allow mounting of a plurality of types of sensors on its top surface and/or recessed within front or rear edges. Such sensors can include visual light cameras for machine vison processes and/or LIDAR of various types and cooperage areas/fields of view—some of which can be recessed within a hollow region of the bar. Additional sensors can be mounted on the truck cab and/or chassis, including visual-light cameras and radars.

Abstract: A sensor interface system for providing a connection between at least one sensor and a maternal-fetal monitor, wherein the interface system converts electrical muscle activity captured by the sensor(s) into uterine activity data signals for use by the maternal-fetal monitor. The sensor interface system of the invention preferably includes a conversion means for converting the signals from the sensor(s) into signals similar to those produced by a tocodynamometer.

Abstract: A pipe coating material removal apparatus, comprising a support frame, a subframe, and one or more coating material removal members. The subframe is supported by the support frame and is configured to rotate relative to the support frame at least partially around a subframe rotation axis. The subframe rotation axis is configured to be substantially coaxial with a longitudinal axis of a pipe to which the apparatus may be applied in use. The, or each, coating material removal member is rotatably mounted to the subframe to remove part of an exterior coating of a pipe. The apparatus is configured such that the one or more coating material removal members enable the removal of pipe coating material at orientations substantially parallel to, and inclined with respect to, the longitudinal axis of the pipe.

Abstract: An intervertebral fusion device comprises a superior component, an inferior component, and a core component. The superior and inferior components are received between first and second vertebrae whereby a superior component top side of the superior component abuts against the first vertebra, and an inferior component bottom side of the inferior component abuts against the second vertebra. The core component is inserted between the superior and inferior components to determine a height of the intervertebral fusion device. First and second core profiles of the core component cooperate respectively with a first component profile of the superior component and a second component profile of the inferior component during insertion of the core component to guide the core component relative to the superior and inferior components.

Abstract: The present invention relates to an intervertebral fusion device (10) comprising a superior component (20), an inferior component (40) receivable in an intervertebral space between first and second vertebrae, with the core component (80) insertable between the superior and inferior components to determine a separation between the superior and inferior components. The superior, inferior components and core components comprise respective formations and profiles. The formations (54, 68) present a barrier to separation of the core from one of the inferior and superior components during insertion of the core component. The profiles guide the core component during insertion of the core component while presenting no barrier to separation from each other during its insertion. The components comprise further formations (39, 76) which present a barrier to separation of the components from each other once the core has been fully inserted between the inferior and superior components.

Abstract: The present invention relates to an intervertebral fusion device (10) comprising a superior component (12), an inferior component (14) and a core component (16). The superior component (12) and the inferior component (14) are receivable in an intervertebral space between first and second vertebrae with the core component (16) insertable between the superior and inferior components to determine a separation between the superior and inferior components. A bone graft conveying aperture is defined in at least one of a superior component top surface (18) of the superior component and an inferior component bottom surface (20) of the inferior component. The core component defines a bone graft material holding space which is enclosed except at at least one of a core component top surface and core component bottom surface of the core component and a bone graft material delivery opening. The bone graft material delivery opening extends from outside the core component side to the bone graft material holding space.

Abstract: An exemplary mobile apparatus for assessing an operating condition of an asset. The mobile device includes at least one sensor device for acquiring data related to one or more operational or environmental characteristics of an asset during operation. The mobile device further includes a processing device encoded with a neural network architecture having one or more models trained to identify one or more operating conditions of one or more assets according to asset type. The processing device can determine an operating condition of the asset by extracting features from the acquired data and comparing attributes of the extracted features to attributes of at least one known operating condition determined through training of the models. The mobile device can also include an output interface to output a result of the determination performed by the processing device, which can include communicating the result to a remote device.

Abstract: A doubly resonant electro-optic converter is provided. An optical resonator and a microwave resonator are disposed such that fields from the two resonators can interact in an electro-optic active medium. The optical resonator is a planar photonic crystal optical resonator, and the microwave resonator is at least partially superconducting in operation. The active medium has a second order nonlinearity capable of generating a sum frequency signal and/or a difference frequency signal from the optical and microwave fields. The resulting structure has both quantum and classical applications.

Abstract: A method and apparatus for recruiting, communicating with, and paying participants of interactive advertising are described. The present invention is a system through which advertisers car recruit, communicate with, and pay their potential customers for their time. The system achieves these functions without the advertiser or the customer having to be in the same location—all logistics are handled through the system's web site, database, and communications interfaces. The system enables advertisers to promote interactive seminars in which they try to sell products to potential customers. Most importantly, the advertisers are able to offer their potential customers financial rewards for their time, such as 25 cents per minute to reward a customer for listening to a sales pitch. The system then provides a real-time communications link between the advertiser and customer. The system automatically bills the advertiser and rewards the customer for the time that they interact.
