An implantable medical device includes a structural body made from a superelastic material and includes one or more marker holders integrally formed on the structural body. Each marker holder is designed to hold a radiopaque marker which has a level of radiopacity greater than the superelastic material. The radiopaque marker can be made from a nickel-titanium alloy which includes a ternary element. The ternary element can be selected from the group of elements consisting of iridium, platinum, gold, rhenium, tungsten, palladium, rhodium, tantalum, silver, ruthenium, and hafnium. In one form, the marker holder includes a pair of projecting fingers connected together at a notched region to cooperatively create a particular-shaped opening. This opening, in turn, is adapted to receive a similarly shaped portion formed on the radiopaque marker. In one form, the radiopaque marker includes an inner core which is partially, or completely, encased by an outer layer. This inner core can be made from a highly radiopaque material while the outer layer is formed from a material that is easier to weld to the marker.

A wireless combination time, frequency and spectral shaping communications method that transmits data in convolution unit matrices (data frames) of N×N (N²), where generally either all N² data symbols are received over N spreading time intervals (each composed of N time slices), or none are. To transmit, the N² sized data frame matrix is multiplied by a first N×N time-frequency shifting matrix, permuted, and then multiplied by a second N×N spectral shaping matrix, thereby mixing each data symbol across the entire resulting N×N matrix (TFSSS data matrix). Columns from this N² TFSSS data matrix are selected, modulated, and transmitted, on a one element per time slice basis. At the receiver, the replica TFSSS matrix is reconstructed and deconvoluted, revealing the data. The method can accommodate multiple users at once, can adapt to changing channel conditions, and is particularly useful for coping with channel impairments such as Doppler shifts.

An implantable middle ear hearing device having a tubular vibration transducer to drive a round window is designed to input sound to a round window opposite an oval window in an inner ear. The tubular vibration transducer has a unique structure that does not attenuate the magnitude of a signal, particularly, in a high frequency band. Sound delivery effect is much higher than those of conventional schemes. It is also possible to minimize difficulties associated with and problems resulting from the operation, which the conventional methods would have. Further, the transducer can have a relatively less compact than ossicle contact type transducers, and thus be easily fabricated. The hearing device can be applied to a sensorineural hearing loss patient with the ossicle damaged. Moreover, since sound is directly transmitted without through the ear drum and the ossicle, high efficiency sound delivery is achievable and hearing loss compensation are easy.

A volumetric error compensation measurement system and method are disclosed wherein a laser tracker tracks an active target as the reference point. The active target has an optical retroreflector mounted at the center of two motorized gimbals to provide full 360 degree azimuth rotation of the retroreflector. A position sensitive detector is placed behind an aperture provided at the apex of the retroreflector to detect the relative orientation between the tracker laser beam and the retroreflector by measuring a small portion of the laser beam transmitted through the aperture. The detector's output is used as the feedback for the servo motors to drive the gimbals to maintain the retroreflector facing the tracker laser beam at all times. The gimbals are designed and the position of the retroreflector controlled such that the laser tracker always tracks to a pre-defined single point in the active target, which does not move in space when the gimbals and/or the retroreflector makes pure rotations. Special mechanism and alignment algorithm are used in the gimbal design and retroreflector centering alignment to achieve accurate rotational axis alignment and repeatability.

Method, systems and software are proposed for obtaining for blocks of a first image similar blocks of a second image (the “reference image”). The blocks of the first image are processed sequentially, for each block trying out a number of candidate locations in the second image and evaluating a cost function for each. Each candidate location in the second image is displaced by a respective motion vector from the block of the first image. In a first aspect of the invention the cost function is a function of a predicted motion vector for future blocks of the first image (i.e. blocks of the first image which have not yet been processed). In a second aspect of the invention the motion vectors are given by location values which are not all whole pixel spacings, halves of the pixel spacing, or quarters of the pixel spacing.

Efficient computer distribution of healthcare information is achieved by computer aggregating the healthcare information directly from multiple sources, namely, computers of healthcare providers, including EHR vendors, and patients. Financial incentives to share information are provided to the sources. Healthcare information may de-identified by removing some specific information about the patient and the provider, and inserting generalized information about each. Healthcare providers and patients may prohibit use of their information, limit the content of their information, and control to whom their information is sold. Compensation and distribution of information among purchasers may be controlled to ensure fairness. The healthcare information may be analyzed, reordered and filtered to generate data or reports in response to a purchase request.

A solid state imager includes an arrangement for converting analog pixel values to digital form on an arrayed per-column basis. An N-bit counter supplies an N-bit DAC to produce an analog ramp output providing a ramp signal with a level that varies corresponding to the contents of the counter. Latches or equivalent digital storage elements are each associated with a respective column. A counter bus connects the counter to latch inputs of said latches, and comparators associated the columns gate the latches when the analog ramp equals the pixel value for that column. The contents of the latch elements are transferred sequentially to a video output bus to produce the digital video signal. There can be additionally black-level readout latch elements, for storing a digital value that corresponds to the dark or black video level, and a subtraction element subtracts the black level value from the pixel value to reduce fixed pattern noise. An additional array of buffer latches can be employed.

A reference timing signal apparatus with a phase-locked loop (PLL) has a computer algorithm which adaptively models the multiple frequencies of an oscillator following a training period. The oscillator is part of a PLL and the oscillation frequency thereof is controlled in response to the phase detector output. The computer algorithm processes the control signal applied to the oscillator. The computer algorithm updates the characteristics of the model relating to the aging and temperature of the oscillator, using for example, a Kalman filter as an adaptive filter, in accordance with a cumulative phase error in the PLL calculated during a given time interval. By the algorithm, the subsequent model predicts the future frequency state of the oscillator on which it was trained. The predicted frequency of the model functions as a reference to correct the frequency of the oscillator in the event that no input reference timing signal is available. Also, the calculated phase error is stored and is used while no input reference timing signal or accurate predicted frequency value is available. With the model updating algorithm, oscillators of low stability performance may be used as cellular base station reference oscillator, which is based on satellite systems, for example, GPS, GLONASS or Galileo systems.
