  • Patent number: 10320063
    Abstract: A wearable computing device can include a monopole-excited slot antenna formed by a gap between a housing (such as a highly conductive housing) and a bracket (such as a highly conductive bracket) within the highly conductive housing and by a back cavity between the highly conductive bracket and the PCB. The antenna configuration can include a monopole antenna electrically coupled to a printed circuit board and a slot antenna that is excited through coupled electromagnetic fields. The highly conductive bracket is positioned near a display window of the device, mostly below and partially enclosing a battery. The highly conductive bracket is positioned above the printed circuit board. This configuration allows for a relatively small dead band in the display window, a larger battery, compact and mechanically simple configuration, and superior water resistance.

  • Patent number: 10312582
    Abstract: An apparatus comprises a radio frequency (RF) antenna circuit; an antenna aperture tuning circuit; an antenna impedance measurement circuit; and a processor circuit electrically coupled to the tunable antenna aperture circuit and the impedance measurement circuit. The processor circuit is configured to: set the antenna aperture tuning circuit to an antenna aperture tuning state according to one or more parameters of an RF communication network; initiate an antenna impedance measurement; and change the antenna aperture tuning state to an antenna aperture tuning state indicated by the antenna impedance.

  • Patent number: 10136543
    Abstract: Mechanisms for providing inductance-based user interface elements are provided. Some implementations of such inductance-based devices may feature very small gaps between the housing and the inductive coil, as well as various features to aid in improving sensor sensitivity and reducing the possibility of false button-push events.

  • Patent number: 8271623
    Abstract: Aspects of the subject matter described herein relate to performing configuration in a multi-machine environment. In aspects, a client connects with one of a plurality of storage appliances. This storage appliance is sometimes called the coordinator appliance. Any of the storage appliances may act as the coordinator appliance. The coordinator appliance receives configuration data from the client and configures itself and the other storage appliances. During configuration, connectivity between the client and the coordinator appliance and between the coordinator appliance and the other appliances may be lost and re-established.

  • Publication number: 20100299619
    Abstract: Described is a reusable software wizard component that is invoked to integrate its elements (e.g., logic, pages, data and/or tasks) with elements of a wizard to provide an integrated wizard. For example, the integrated wizard may provide customized wizard functionality yet be efficiently developed by the use of at least some re-useable elements. In one implementation, the reusable software wizard component corresponds to a class having interfaces/functions for getting its data, pages and/or tasks. The selected pages and/or tasks may be integrated with pages and tasks of the wizard in any suitable order. Pages from the reusable software wizard component may be pre-filled with data from the wizard.
