  • Publication number: 20160028677
    Abstract: Methods and systems for providing notifications to mobile device utilize a cloud extension agent operating on a corporate network for sending notification requests via a cloud-based service. An application on the user's mobile device is configured to receive push notifications sent via the cloud extension agent, while receiving email messages directly from corporate email server. A user can select notification settings, allowing the cloud extension agent to be configured remotely via a cloud to provide appropriate notifications to the user.

  • Patent number: 8997258
    Abstract: A microscope probe includes a substrate; an optical resonator disposed on the substrate and including an optical resonance property; a displacement member disposed on the substrate and separated from the optical resonator, the displacement member including: a first end disposed distal to the optical resonator; and a second end disposed proximate to the optical resonator; and a coupling member disposed on the substrate and connecting the displacement member to the substrate, wherein the first end is configured to probe a sample and to be displaced in response to a condition of the sample, the displacement member is configured to communicate displacement of the first end to the second end, and the second end is configured to change the optical resonance property in response to displacement of the second end.

  • Publication number: 20100185693
    Abstract: Extensible data management system and methods for enabling participants (providers and customers) in a software-as-a-service (SaaS) environment to define audit configurations for generating an audit trail tailored to a customers' business needs. A participant in the SaaS environment may define an extension to the data management system, wherein the extension is associated with a node representing the participant in a hierarchical data structure. The position of the participants in the hierarchical data structure ensures audit configurations created by one customer do not affect the functionality of other customers in the SaaS environment.

  • Patent number: 7092421
    Abstract: An optoelectronic transducer comprises a unipolar, intraband active region and a micro-cavity resonator. The resonator includes a 2D array of essentially equally spaced regions that exhibits resonant modes. Each of the spaced regions has a depth that extends through the active region and has an average refractive index that is different from that of the active region. The refractive index contrast, the spacing of the spaced regions, and the dimensions of the spaced regions are mutually adapted so that the array acts as a micro-cavity resonator and so that at least one frequency of the resonant modes of the array falls within the spectrum of an optoelectronic parameter of the active region (i.e., the gain spectrum where the transducer is a laser; the absorption spectrum where the transducer is a photodetector). In a first embodiment, the transducer is an ISB laser, whereas in a second embodiment it is a unipolar, intraband photodetector.
