  • Publication number: 20180061391
    Abstract: An earphone adapted to fit within a human ear that generates sound via the propagation of one or more diaphragms aligned to fit the structure and shape of the earphone. The earphone allows ambient sound to pass through the device in order to be heard by the user. The earphone includes a variety of sensors adapted to characterize the surrounding acoustic environment and actively negate undesired sounds by generating a cancelling signal specific to the undesired sound or sounds. The earphone allows users to select particular sounds to cancel or to negate all of the surrounding noise. The earphone itself can be used to characterize repetitive environmental sounds that are predictable by the system. Additionally, the earphone can be used in conjunction with a buffering device in communication with a source of non-repetitive, unpredictable sounds in order to characterize and negate those sounds.

  • Publication number: 20180062607
    Abstract: A transformer-based balun circuit s disclosed herein. The balun can be implemented using a spiral transformer, where primary and secondary transformer windings can be inductively coupled and can be implemented on the same metal layer (or different metal layers, e.g. vertically adjacent metal layers). The balun can further include a compensation capacitor and a digital frequency tuning circuit. The compensation capacitor can be introduced at one of the differential terminals to reduce or suppress the amplitude and phase imbalance. The digital frequency tuning circuit can be a switchable bank of capacitors, which allows for tuning the frequency of operation of the transformer-based balun.

  • Patent number: 9803329
    Abstract: The expansive soil resistant foundation system includes a foundation frame having footings forming a grid pattern. The grid pattern contains a plurality of spaces within the pattern. Each space defines a main swell duct. Each main swell duct may be provided with one or more sub-swell ducts. The swell ducts permit free expansion and contraction of the expansive soil. A vent extends from each swell duct to expel trapped air. A drainage system is distributed throughout the foundation frame to eliminate accumulation of underground water. The swell ducts, vents, and the drainage system alleviate potential pressures that can be exerted on the foundation from the expansion and contraction of the expansive soil, which can lead to cracks and structural failure.

  • Patent number: 9800946
    Abstract: This invention describes a cloud-based architecture that orchestrates the detection and dissemination of highly-dynamic, real-time, and fine-grained TV white space information to improve spectrum information used for White Space Devices (WSDs). Wasted spectrum opportunities were first identified, both temporal and spatial, due to the current approach of white spaces detection. This invention introduces a next generation of geo-location databases capable of tracking the state of the relatively static TV transmitters and the highly dynamic TV receivers. A quantitative evaluation of the potential gain in white space availability for large scale deployments of this novel architecture demonstrated significant improvement in the availability of white spaces.

  • Publication number: 20170272073
    Abstract: Methods and systems for operating a programmable logic fabric including a dynamic parameter scaling controller that tracks an operating parameter that functions at multiple operating conditions by maintaining the operating parameter while cycling through a multiple operating conditions during a calibration mode using the calibration configuration for the programmable logic fabric. The dynamic parameter scaling controller also stores one or more functional values for the operating parameter in a calibration table. The dynamic parameter scaling controller also operates the programmable logic fabric using a design configuration using dynamic values for the operating parameter based at least in part on the one or more operating conditions.

  • Patent number: 9643889
    Abstract: The method of storing exfoliated nanoclay particles involves the freezing of exfoliated nanoclay particles in water, thus forming ice with the exfoliated nanoclay particles suspended therein. The frozen state of the suspension prevents the exfoliated nanoclay particles from agglomerating, thus allowing the nanoclay particles to be stored and transported while maintaining their exfoliated state. The exfoliated nanoclay particles are added to the water to form a suspension, and the suspension is then mixed for between 24 and 72 hours to ensure that no agglomerated nanoclay particles are in suspension and that the suspension contains only exfoliated nanoclay particles. The suspension is then frozen to store the exfoliated nanoclay particles in ice.

  • Patent number: 9406054
    Abstract: Virtual account based digital cash protocols employ two pairs of private and public keys. Each public key is certified separately and the protocols do not use any blind signature schemes. As a result, the virtual account based digital cash protocols provide strong protection of the user privacy by using two certified public keys instead of a blind signature. One pair of certified keys consists of one master user private key and one master user public key. A second pair of certified keys consists of one pseudonym user private key and one pseudonym user public key. The use of a master key pair and a pseudonym key pair circumvents the need for blind signatures. As a result, the proposed protocols do not require blind signatures and do not add additional overhead and security requirements necessitated by conventional blind signature schemes.

  • Publication number: 20160095599
    Abstract: A bioresorbable drug-eluting biopolymer suture-free blood vessel anastomosis devices can be deployed to join two blood vessels and resorbed by the body over a predetermined time period after the blood vessel has become joined. The anastomosis device can include a hollow tube that is inserted interconnect the two vessels to be jointed. A non-piercing suture is wrapped around the vessel to secure the anastomosis. The anastomosis device can include hollow tube that extends along an axis from a first end to a second end. The ends can be fitted with elements that facilitate mechanical attachment of the vessel to the anastomosis device and provide for a secure seal.

  • Patent number: 9171324
    Abstract: The hybrid virtual account and token-based digital cash protocols provide a user with many pairs of secret and public keys. One of the pairs is the master pair, which consists of one master user private key and one master user public key. Other pairs are pseudonym pairs, wherein each consists of one pseudonym user private key and one pseudonym user public key. The use of a master key pair and pseudonym key pairs circumvents the need for blind signatures. None of the invention's protocols require blind signatures. The protocols comprise public key protocols, digital signatures and symmetric key protocols.
