  • Publication number: 20170317395
    Abstract: An electromagnetic coupler includes a dielectric layer with a first transmission line connecting an input port to an output port. A second transmission line on another surface of the dielectric layer forms a coupled port and an isolation port. The electromagnetic coupler provides a coupled signal at the coupled port, which is representative of an input signal at the input port. The amplitude of the coupled signal is related to the amplitude of the input signal by a coupling factor. A tuning element on the dielectric layer is configured to stabilize the coupling factor over a range of variations in thickness of the dielectric layer.

  • Publication number: 20170317396
    Abstract: An electromagnetic coupler includes a first transmission line connecting an input port to an output port. A second transmission line adjacent the first transmission line connects a coupled port and an isolation port. The electromagnetic coupler provides a coupled signal at the coupled port, which is representative of an input signal at the input port. The amplitude of the coupled signal is related to the amplitude of the input signal by a coupling factor. A tuning element is provided adjacent to the first or second transmission line and is coupled to an impedance. Varying impedance values cause an adjustment to the coupling factor and reactive impedance values provide frequency filtering effects.

  • Patent number: 9766327
    Abstract: A sensor such as a presence sensor for use in a lighting system or other system that adapts to information from a plurality of active presence sensors. If transmissions from the active sensors are uncoordinated, the overall detection performance may be adversely impacted (e.g. due to potential cross-interference), which may make sensing over the detection coverage area defined by a single presence sensor (or the like) become unreliable. The disclosure presents protocols for coordinating transmissions in active sensing systems. The invention may be applied to various active modalities (e.g. ultrasound, RF), for example that find applications in indoor and outdoor lighting controls.

  • Publication number: 20170218749
    Abstract: A tomographic imaging apparatus utilizes Compton backscattering to evaluate cement behind the casing. The imaging apparatus includes a slant-hole or pin-hole collimator coupled to a series of detectors in order to count the number of photons that backscatter off from the cement. The number of backscattered photons is proportional to the density of the cement behind the casing. Using the photon count, an image processing unit of the imaging apparatus generates a 2D or 3D tomographic image of the borehole.

  • Publication number: 20170200454
    Abstract: An audio stream is encoded for transmission to a receiving device via a communications channel. The to-be transmitted audio stream is received at an audio encoder executed on a processor. The processor has an amount of available processing resources. An available bandwidth of the communications channel is determined. Based on the determined bandwidth, a portion of the available processing resources is allocated to the audio encoder. The allocated portion is greater if the determined bandwidth is below a bandwidth threshold. The audio encoder encodes the audio stream using the allocated portion of processing resources, and transmits the encoded audio stream to the receiving device via the communications channel.

  • Patent number: 9659574
    Abstract: A noise attenuation apparatus receives a first signal comprising a desired and a noise signal component. Two codebooks (109, 111) comprise respectively desired signal candidates and noise signal candidates representing possible desired and noise signal components respectively. A noise attenuator (105) generates estimated signal candidates by for each pair of desired and noise signal candidates generating an estimated signal candidate as a combination of the desired signal candidate and the noise signal candidate. A signal candidate is then determined from the estimated signal candidates and the first signal is noise compensated based on this signal candidate. A sensor signal representing a measurement of the desired source or the noise in the environment is used to reduce the number of candidates searched thereby substantially reducing complexity and computational resource usage. The noise attenuation may specifically be audio noise attenuation.

  • Patent number: 9426155
    Abstract: A cloud deployment appliance (or other platform-as-a-service (IPAS) infrastructure software) includes a mechanism to deploy a product as a “shared service” to the cloud, as well as to enable the product to establish a trust relationship between itself and the appliance or IPAS. The mechanism further enables multiple products deployed to the cloud to form trust relationships with each other (despite the fact that each deployment and each product typically, by the nature of the cloud deployment, are intended to be isolated from one another). In addition, once deployed and provisioned into the cloud, a shared service can become part of a single sign-on (SSO) domain automatically. SSO is facilitated using a token-based exchange. Once a product registers with a token service, it can participate in SSO. This approach enables enforcement of consistent access control policy across product boundaries, and without requiring a user to perform any configuration.
