Abstract: Embodiments of the invention address deficiencies of the art in respect to digital signal transmissions and provide a novel and non-obvious fall time accelerator circuit for use in a USB interface. In one embodiment of the invention, the USB interface can include a USB port driver coupled to a host controller driver over a USB bus. The USB interface also can include a fall time accelerator circuit coupled to the USB bus between the USB port driver and the host controller driver. The fall time accelerator circuit can include a pulse signal generator coupled to an inbound signal path from the USB bus and arranged to generate a tunable pulse upon detecting a falling edge of a digital signal on the inbound signal path. The circuit further can include an active timer additionally coupled to the inbound signal path to hold the tunable pulse for a set period of time. Finally, the circuit can include a falling drive signal strengthener coupled to an outbound signal path from the pulse signal generator arranged to release the tunable pulse on the outbound signal path onto the USB bus.

Abstract: Settings are provided by a chassis management controller to an expansion card in a multi-slot server chassis. The chassis management controller in a multi-slot server chassis provides an operating parameter to a server management controller in a server, and the server management controller writes the operating parameter to a port expander of an expansion card installed on the server. The operating parameter is written to the port expander prior to expansion card power up, and the expansion card uses the operating parameter after power up to derive one or more SERDES value. The SERDES value is used to program an ASIC chip comprising a SERDES converter on the expansion card. In one example, the operating parameter is determined by the capabilities of a chassis midplane at the slot where the compute node is installed.

Abstract: Method and computer program product for using an RFID antenna of a cooking appliance to read a plurality of cooking instruction sets from a single RFID tag associated with a food product that is positioned to be cooked by the cooking appliance. The cooking appliance selects one of the plurality of cooking instruction sets that the cooking appliance is capable of performing. Furthermore, the cooking appliance may then automatically cook the food product by controlling the cooking appliance according to the selected cooking instruction set. The selection of a cooking instruction set may consider the temperature of the food product or a determination whether the food product is frozen. Alternatively, cooking appliance settings may be interpolated between two cooking instruction sets or calculated on the basis of physical property information about the food product.

A first transceiver subsystem is configured for communicating over the serial bus network between the management module and each server within a first frequency band. A second transceiver subsystem is configured for simultaneously communicating over the serial bus network between the management module and the servers within a second frequency band higher than the first frequency band. A first signal-filtering subsystem substantially filters out signals in the second frequency band from the first transceiver subsystem. A second signal-filtering subsystem substantially filters out the signals in the first frequency band from the second transceiver subsystem.

Abstract: A method of electrically qualifying high speed printed circuit board (PCB) connectors includes mounting a PCB connector on a test card, sending bit patterns through a first portion of the test card, evaluating a waveform on a sense signal on a second portion of the test card for the bit patterns launched on said first portion of the test card to measure common mode noise, and comparing the measured common mode noise of the second portion of the test card to a golden standard performed on a pre-qualified connector. The first portion of the test card comprises connectors to inject bit patterns. The second portion of the test card includes a split plane which induces common mode noise on a sense signal, the sense signal, and a termination pack. If the measured common mode noise on the PCB connector is worse than the golden standard, then the PCB connector is disqualified. If the measured common mode noise on the PCB connector is as good as or better than the golden standard, then the PCB connector is qualified. A first section of the PCB connector connects to the first portion of the test card and a second section of the PCB connector connects to the second portion of the test card. Transmission lines in the test card and the sense line are tightly coupled by shortening a distance between the sense line and the transmission lines.
