  • Patent number: 10313024
    Abstract: The present disclosure is generally directed to a transmitter optical subassembly (TOSA) having a hermetically-sealed housing with a feedthrough device that electrically isolates RF and power traces. In more detail, a TOSA consistent with the present disclosure includes a substrate with driving circuitry disposed thereon. A first end of the substrate may electrically couple to transmit connecting circuitry and a second end may couple to a hermetically-sealed housing. The hermetically-sealed housing can include one or more laser packages for emitting associated channel wavelengths in addition to monitor photodiodes (PDs), and temperature control devices such as TECs. The hermetic-sealed housing includes a first end with a feedthrough device that provides traces to electrically couple to the circuitry of the substrate. The hermetic-sealed housing further includes an optical coupling port, e.g., a LC connector, for coupling to an external fiber, for example.

  • Publication number: 20190077323
    Abstract: An operating system for moving an item stored in a vehicle storage device is provided. The storage device includes a first storage container and a second storage container disposed in the storage device. The operating system comprises a first operating device connected to the first storage container; a second operating device connected to the second storage container; a user intention detecting device for detecting an intention of a user to take an item; and a controller. The controller is configured to receive an intention signal from the user intention detecting device and control one of the first and second operating devices based on the intention signal obtained to move the first or second storage containers to a use position which is easier for the user to take the item.

  • Patent number: 10230470
    Abstract: In accordance with an embodiment, a multi-layered flexible printed circuit (FPC) is disclosed that includes two or more insulating layers to route conductive traces carrying radio frequency (RF) signals, e.g., data signals, and conductive traces carrying direct current (DC) signals, e.g., power signals and low-frequency control signals, while sufficiently isolating the RF signals from electrical interference by the DC transmission lines. This advantageously eliminates having two or more separate FPCs to electrically couple each optical subassembly, e.g., receiver optical subassemblies (ROSAs) and transmitter optical subassemblies (TOSAs), to associated circuitry in a transceiver housing, which saves space and reduces manufacturing complexity, for example.

  • Publication number: 20190067883
    Abstract: A smart electrical plug supports one or more electrical outlets and one or more universal serial bus (USB) outlets for charging electrical devices. Electrical power consumed through the one or more electrical outlets may be measured individually or in combination and reported via a wireless communication channel. The smart electrical plug may be implemented by a plurality of printed circuit board assemblies and distributed within a housing to reduce the effects of heat dissipation. The smart electrical plug may further reduce heat dissipation by utilizing one or more electrical circuit approaches.

  • Patent number: 10157412
    Abstract: A system and method for generating a recommendation counter for a business entity based on social networking interactions is provided. In an embodiment, a social networking server provides an interface for users of social networking accounts to request recommendations for business entities and to reply to the requests with recommendations. When the social networking server computer receives a recommendation for a particular business entity, the social networking server computer determines whether the recommending social networking account has recommended the particular business entity in the past. In response to determining that the social networking account has not recommended the particular business entity in the past, the social networking server computer increments a recommendation counter for the particular business entity.

  • Patent number: 9753841
    Abstract: According to a computer-implemented method, a determination is made of content of an inbound request that is received at a composite software application from a client. The composite software application utilizes features from an application component that is deployed independently from the composite software application. A determination is made of content of an outbound request that is transmitted from the composite software application to the application component, with the outbound request being triggered by the inbound request. A determination is also made of content of a response to the inbound request that is transmitted from the composite software application to the client. The content of each of the inbound request, the response to the inbound request, and the outbound request are recorded in a repository as a baseline test case for regression testing of the composite software application.

  • Patent number: 9747262
    Abstract: A method includes extracting text elements from a webpage, storing the text elements in a data structure, and comparing the text elements in the data structure with a Document Object Model (DOM) structure of the webpage. The extracted text elements may then be processed and exported to a display format. Information from a webpage can, therefore, be extracted for processing using other applications regardless of how the elements were coded to form the webpage.
