  • Publication number: 20190102011
    Abstract: The disclosure relates to a touch screen including a first electrode layer, a second electrode layer, and a third electrode layer. The touch screen can include shield-sensor vias connecting the first electrode layer and the second electrode layer and shield-shield vias connecting the first electrode layer and the third electrode layer, for example. The shield-sensor vias can be placed in a bond pad region of the touch screen, which can further include connections between one or more routing traces connected to one or more touch electrodes and touch or other circuitry further included in the electronic device. The shield-shield vias can be placed in an outer region located around an inner region of the touch screen. In some examples, one or more routing traces can include diverted portions to maintain a threshold distance between the routing traces and the one or more shield-shield vias.

  • Publication number: 20190058543
    Abstract: A technique for testing wireless-local-area-network (WLAN) infrastructure is described. In particular, a radio-frequency abstraction layer (RFAL) in a physical instance of an electronic device is used to simulate the physical layer communication hardware and radio channels. RFAL allows frames in initial packets that are compatible with a WLAN communication protocol (such as an IEEE 802.11 standard) to be encapsulated in the data-link layer into additional packets that are compatible with a network communication protocol (such as an IEEE 802.3 standard). These additional packets can include information that characterizes transmission of the packet through a simulated radio-frequency environment so that the software stack associated with a physical or virtual instance of an electronic device can be exercised as if the packet had been received over a wireless connection. Then, the additional packets can be communicated via Ethernet (i.e.

  • Publication number: 20190014860
    Abstract: The present disclosure describes a shoe that may be transformed from a high heel shoe to a low heel shoe. The shoe may include three parts: a removable stelo, a removable high heel attachment, and the corresponding attachment systems integrated into the base shoe sole. The removable high heel attachment may be a standard heel of any design, width and height that has a locking system comprising a threaded post located at the heel base. When the stelo and heel attachment are attached, the shoe may be a high heel shoe. When they are removed, the shoe may be a low heel shoe, or flat shoe.

  • Publication number: 20180227835
    Abstract: A communication technique for establishing communication among an access point, an electronic device, and a radio node in a cellular-telephone network is described. In this communication technique, the electronic device is pre-provisioned by the radio node with an identifier of the cellular-telephone network. Moreover, the access point may advertise support for one or more LWA protocols in beacons. In response to a query from the electronic device, the access point may provide identifiers of the one or more cellular-telephone networks supported by the access point. If one of these identifiers matches the identifier, the electronic device may associate with the access point. Then, the access point may receive LWA traffic from the radio node and may forward the LWA traffic to the electronic device.

  • Publication number: 20180063714
    Abstract: A technique for establishing connectivity between electronic devices is described. In particular, when an electronic device is first connected to a network, the electronic device may use a predefined location of a registrar device to request location information for a controller for the electronic device. The electronic device may provide a manufacturer certificate to the registrar device to confirm its identity. After receiving from the registrar device the location information and a registrar certificate that confirms its identity, the electronic device may use the location information to request the security information from a controller that allows the electronic device to establish connectivity with another electronic device. The electronic device may receive the security from the controller along with a controller certificate that confirms the identity of the controller. Moreover, the electronic device may establish a connection with the other electronic device based on the security information.

  • Publication number: 20180026841
    Abstract: In order to configure an access point, the access point requests information specifying an associated cloud-based controller when the access point is first turned on at a user location. In particular, the access point may provide, to a configuration device, a controller query requesting information specifying a unique network address of a cloud-based controller associated with the access point. This controller query may include an identifier of the access point (such as a serial number). Then, the access point receives, from the configuration device, the information specifying the unique network address of the cloud-based controller, such as a fully qualified domain name of the cloud-based controller. Note that the cloud-based controller may be one of multiple cloud-based controllers from different providers, and the access point may be associated with the cloud-based controller based on the received information specifying unique network address.

  • Publication number: 20170234193
    Abstract: A diesel exhaust fluid (DEF) tank for an off-road vehicle including a retaining bar configured to support the DEF tank and a channel molded into a side of the DEF tank. The channel is configured to interface with the retaining rod. The DEF tank further including a cutout formed within the channel, wherein the cutout establishes a gap between the retaining bar and a body of the DEF tank. The DEF tank also includes a drain channel molded into an exterior surface of the DEF tank. The drain channel is configured to provide structural support to the DEF tank, and the gap is configured to enable DEF flow downwardly into the drain channel without contacting the retaining bar.
