  • Patent number: 8609184
    Abstract: A system and method for corrosion problems in magnetic media resulting from moisture penetrating through the carbon layer into the magnetic layer by diffusion or other methods are overcome by processing the carbon overcoat to stop and/or inhibit the moisture penetration. The process involves removing moisture channels from protective overcoats of thin film magnetic media by irradiating the protective overcoat with ultraviolet (UV) radiation in an inert hydrophobic chemical environment. Afterwards, the thin film magnetic media can be removed into ambient atmosphere where it is coated with a lubricant.

  • Patent number: 8499630
    Abstract: A MEMS piezoelectric sensor comprises a plurality of capacitors some of which may be used for sensing and others used for feedback. The capacitors may be switched to connect or disconnect selected capacitors from the sensor. Embodiments convert a two port sensor into a four port sensor without significant changes in hardware design and improve SNR and correct for offset and out-of-axis errors due to process mismatch and variations.

  • Publication number: 20130143588
    Abstract: A method and system for a cellular mobile communication system (900) are provided. The location of a mobile communication unit (905) in the cellular wireless communications system (900) can be estimated from: a first estimate of position, based on received signal power difference for signals received by the mobile communication unit (905) from at least two base stations (910); and a second estimate of the position of the mobile communication unit (905), from further information. A likelihood function for each estimate is weighted. The weighted first and second likelihood functions are combined, and one or more locations are selected as the estimated location. Propagation model parameters may be iteratively updated and/or refined, using location estimates obtained for large numbers of calls in the cellular mobile communication system (900).

  • Patent number: 8264941
    Abstract: An arrangement, a method and a system to read information stored in a layer of ferroelectric media. The arrangement includes a layer including a ferroelectric media having one or more ferroelectric domains holding bit charges, a domain corresponding to information; a probe having a tip, wherein the media and the tip are adapted to move relative to one another such that the tip scans the ferroelectric domains of the media while applying a contact force to the domains to generate a direct piezoelectric effect within the domains; and circuitry coupled to the tip and adapted to generate a signal in response to an electrical coupling between the tip and the domains while scanning the tip in contact with the domains, the signal corresponding to a readout signal for ferroelectric bit charges stored in the media.

  • Publication number: 20120196384
    Abstract: Systems and methods for detecting the presence of biomolecules in a sample using biosensors that incorporate resonators which have functionalized surfaces for reacting with target biomolecules. In one embodiment, a device includes a piezoelectric resonator having a functionalized surface configured to react with target molecules, thereby changing the mass and/or charge of the resonator which consequently changes the frequency response of the resonator. The resonator's frequency response after exposure to a sample is compared to a reference, such as the frequency response before exposure to the sample, a stored baseline frequency response or a control resonator's frequency response.
