20090012420Ear Canal Pressurization Device - An ear canal pressurization device optimized for aural acoustic immittance testing is disclosed. The preferred embodiment of the device is comprised of a rigid mounting framework which holds in position, axially aligned, a first flexible chamber assembly, a centrally disposed forcer assembly, and a second flexible chamber assembly. The forcer assembly comprises a ferromagnetic bobbin and coil that provides electromotive force for a moving magnet linear motor. The motor is comprised of a rigid chamber link, which passes through the hollow core of the bobbin, with a ferromagnetic keeper washer and axially aligned rare earth ring magnet at either end, with like magnetic poles facing each other. The motor is elastically suspended between the first and second flexible chambers. Current flow through the coil of the forcer assembly provides motive force for the motor via attraction or repulsion of the motor magnets and movement of the motor increases the volume of the first flexible chamber while decreasing the volume of the second flexible chamber, or vice versa. The internal volume of the first flexible chamber is coupled via an air line to an ear canal and through a controlled valve to a small vent, and the internal volume of the second flexible chamber is vented to ambient air pressure. Changes in volume of the first flexible chamber, due to motor movement, produce changes in ear canal pressure re Boyle's law. The vent may be opened to allow ear canal pressure to gently equalize to ambient air pressure or to generate ear canal pressure sweeps free of pressure baseline offset. The vent may be closed to set a static ear canal pressure or to generate ear canal pressure sweeps with an incidental baseline offset. The vent may be controlled to generate ear canal pressure sweeps with an intended baseline offset. The device produces ear canal pressure proportional to drive voltage, so any desired pressure versus time function can be generated by applying a coil driving voltage with the appropriate amplitude versus time function. The device operates quietly to avoid interference with aural acoustic immittance measurement, and should have a long and maintenance free life span.01-08-2009

Systems and devices for carrying out the presented methods are also described.12-17-2009
20100268067SYSTEMS, METHODS, APPARATUSES, AND COMPUTER-READABLE MEDIA FOR IMAGE GUIDED SURGERY - Presented herein are methods, systems, devices, and computer-readable media for image guided surgery. The systems herein allow a physician to use multiple instruments for a surgery and simultaneously provide image-guidance data for those instruments. Various embodiments disclosed herein provide information to physicians about procedures they are performing, the devices (such as ablation needles, ultrasound wands or probes, scalpels, cauterizers, etc.) they are using during the procedure, the relative emplacements or poses of these devices, prediction information for those devices, and other information.

20110130641IMAGER FOCUSING BASED ON INTRAOPERATIVE DATA - Various embodiments herein provide for imager focusing based on intraoperative data. Ideally, an imaging plane of an ultrasound transducer would be truly planar. That is not the case, though. Instead, ultrasound transducers image a volume that is closer to a rectangular volume, but that has focal depths or areas in the imaged volume that are “thinner” and provide a better resolution. In general, embodiments herein may include determining the pose of an imager, such as an ultrasound transducer, and the pose of a location of interest. Based on those poses, a focal adjustment may be determined in order to, for example, better focus the imager on the object of interest. Then data is generated and the focus of the imager is adjusted. Additionally, imaging data and/or the object of interest may be displayed. In other embodiments, estimated projections of medical devices are displayed to allow for better intraoperative planning.06-02-2011

High-resolution imagery provides greater detail of the tissue surface, but requires high-speed depth-frame imaging to provide timely updated depth information. A pattern of light, such as a point of light for example, may be projected onto the tissue surface and a reflected image analyzed to determine depth information. The point of light can be projected and analyzed quickly to produce faster depth-frame image rates. Three-dimensional structured-light depth resolution information may be generated and combined with either a two-dimensional image or a two-dimensional stereo image to provide three-dimensional imagery of the tissue surface. Switching between three-dimensional images and one of the two-dimensional image and a two-dimensional stereo image may also be provided. Further, the three-dimensional structured- light depth information may be further optimized by combining it with three-dimensional stereo-correspondence depth information to generate hybrid three-dimensional imagery.03-10-2011

In one embodiment, a mobile device emulates electronic coupon data associated with an electronic coupon as electronic gift card data, and transmits this emulated coupon data to a contactless payment terminal that has the ability to read and processes electronic gift card data. Therefore, the invention may permit a user to make a payment using an electronic coupon at a contactless payment terminal that is not configured to read the native data format of the electronic coupon.08-09-2012
20120221475MOBILE TRANSACTION DEVICE SECURITY SYSTEM - Embodiments of the invention include apparatuses, methods, and computer-program products that provide for a unique financial transaction security system. In one embodiment, the financial transaction security system receives a security protocol from a user. The security protocol includes instructions for allowing transactions without authentication and security features for the user if authentication is necessary. The system then determines that the user is conducting a transaction, evaluates the instructions, and determines whether the transaction can occur without authentication. If the user is required to authenticate his identity, the system requests input from the user, compares the input to the security feature, and determines if the user is authenticated. The user is able to customize both the instructions and the security features to provide greater control over financial transaction security.08-30-2012
