  • Publication number: 20240138064
    Abstract: A method of fabricating a multilayer circuit board is provided which includes forming a layer of a the multilayer circuit board with an internal clearance region having a modified voltage-to-ground clearance of conductive material adjacent to an aperture of the multilayer circuit board. The modified voltage-to-ground clearance of conductive material is based on a configuration of a connector pin to be press-fit connected within the aperture of the multilayer circuit board, and the internal clearance region is enlarged in a direction of greatest normal force outward from the aperture with insertion of the connector pin into the aperture.

  • Publication number: 20240138074
    Abstract: A method for forming an electronic device that includes solder bonding pins from a component to plated through holes of a board, the component being positioned on a first side of the board; and applying solder paste to openings of the plated through holes on a second side of the board opposite the first side of the board that the component is positioned on. The method can further include drawing the solder paste to the pins to provide a reworked solder bond bonding at least one of the pins to the plated through hole.

  • Publication number: 20230153263
    Abstract: An apparatus includes processing hardware, storage hardware, and serial communication hardware. The processing hardware receives selection of a serial communication protocol. The serial communication protocol is selected amongst multiple serial communication protocols to control operation of a power converter. Via the processing hardware or other suitable entity, the storage hardware is populated with a set of command decode functions (a.k.a., command descriptors) assigned to the selected serial communication protocol. During operation, the serial communication hardware receives commands over a serial communication interface and executes the received commands via the set of command decode functions in the storage hardware. Each of the multiple commands communicated over the serial communication interface is encoded in accordance with the selected serial communication protocol. The serial communication hardware uses the set of command decode functions to execute the received commands.

  • Patent number: 10459670
    Abstract: A method of facilitating printing of a digital image based on image splitting is disclosed. The method may include receiving, using a communication device, the digital image from a user device. Further, the method may include analyzing, using a processing device, the digital image. Further, the method may include determining, using the processing device, at least one image characteristic based on the analyzing of the digital image. Further, the method may include generating, using the processing device, a plurality of image segments based on the at least one image characteristic. Further, the method may include storing, using a storage device, the plurality of image segments. Further, the method may include transmitting, using the communication device, the plurality of image segments to the user device.

  • Patent number: 6502805
    Abstract: A highway guardrail system comprises a plurality of posts; a plurality of spacers attached to respective posts; and a rail attached to the spacers. The post comprises a tube formed from sheet material, including overlapping portions facing toward the highway when installed; and a plurality of connectors to join said overlapping portions together. The spacer comprises a member formed from sheet metal blank including a rail attachment portion, a post attachment portion and a bridge portion connecting said rail and post attachment portions. The rail attachment portions and the bridge portion form an acute angle in plan view; and the bridge portion is tapered from wide to narrow toward the post attachment portion. The rail is tubular formed from sheet metal, including a U-shaped member and a sheet metal plate both having overlapping portions; and a plurality of connectors to join said overlapping portions together.

  • Patent number: 4852154
    Abstract: A pay-per-view CATV system which is interfaced with the switched public telephone system is described. A subscriber selects a specific scheduled television event by dialing a telephone number which uniquely identifies the selected event. The called and originating numbers are identified, digitized and combined to form a digital word. The digital word is then transmitted to the CATV supplier.
