  • Publication number: 20200073052
    Abstract: In general, a TOSA consistent with the present disclosure includes a light driving circuit coupled to a hermetically-sealed light engine. The hermetically-sealed light engine includes a housing defined by a plurality of sidewalls. The housing defines a cavity that is hermetically-sealed to prevent introduction of contaminants that would otherwise reduce optical power. The hermetically-sealed light engine optically couples to an external arrayed waveguide grating (AWG), or other multiplexing device, by way of an optical receptacle. The optical receptacle can include a waveguide implemented external to the hermetically-sealed cavity and can include, for instance, an optical isolator, fiber stub, and fiber ferrule section. Thus, the external AWG and associated external optical coupling components advantageously allow for the hermetically-sealed light engine to have a cavity with dimensions relatively smaller than other approaches that dispose an AWG and associated components within a hermetically-sealed cavity.

  • Publication number: 20200041736
    Abstract: The present disclosure is generally directed to an on-board ROSA arrangement where a fiber receptacle element, optical components such as optical de-multiplexer (e.g., an arrayed waveguide grating (AWG)), turning mirror, photodiodes and light receiving chip are mounted to a common substrate. The fiber receptacle element includes a body that defines a slot to at least partially receive an end of the substrate and mount thereto. The body of the fiber receptacle further includes an aperture that extends through the body to receive an optical fiber and/or associated connector and align the same with ROSA components mounted on a surface of the substrate. The fiber receptacle body may be solid, e.g., formed from a single, monolithic piece of material, and may be manufactured from metal, plastic or other suitably rigid material.

  • 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.
