Patent number: 9809842Abstract: Systems, devices, and methods for accurately imaging chemiluminescence and other luminescence are disclosed. A compact, flat-bed scanner having a light-tight enclosure, one or more detector bars of linear charge-coupled device (CCD) or complementary metal oxide semiconductor (CMOS) imaging chips, and high working numerical aperture (NA) optics scans closely over a sample in one direction and then the opposite direction. Averages or other combinations of intensity readings for each pixel location (x, y) between the two or more passes are averaged together in order to compensate for luminescence that varies over time. On-chip pixel binning and multiple clock frequencies can be used to maximize the signal to noise ratio in a CCD-based scanner.Type: GrantFiled: March 24, 2014Date of Patent: November 7, 2017Assignee: LI-COR, Inc.Inventors: Ahmed Bouzid, Chris Lesiak, Daniel W.

Patent number: 7630431Abstract: A data message decoder for high-speed serial bus applications includes a sync pattern decoder that is operated in parallel and simultaneously with a message bit decoder. By operating the sync pattern decoder and the message bit decoder in parallel and simultaneously a true sync pattern following a valid looking sync pattern may be identified and the decoding of the bit message following the valid looking sync pattern may be aborted once the true sync pattern is detected. The data message decoder is robust and tolerant of bus anomalies that are typical when using high frequency signaling on a multipoint serial bus. The robust data message decoder is suitable for, but not limited to, applications in the aerospace industry, such as onboard network systems for advanced commercial and military aircraft.Type: GrantFiled: May 27, 2005Date of Patent: December 8, 2009Assignee: The Boeing CompanyInventors: Daniel W.

Patent number: 7617330Abstract: A system and method is provided for communicating with at least one network device via a network bus comprising a bus controller and a host computer. The bus controller executes a series of instructions, which can be transferred to the bus controller from the host computer. The instructions are executed in a manner independent of the host computer so as to reduce the workload of the host computer. Since the bus controller can execute the series of instructions without further intervention of the host computer, the host computer can perform other operations concurrent with the execution of the series of instructions by the bus controller. In one embodiment, at least one of the instructions has an associated data field that is variable and can be altered by the host computer, such that the host computer can alter the instruction used by the bus controller.Type: GrantFiled: April 26, 2002Date of Patent: November 10, 2009Assignee: The Boeing CompanyInventors: Philip J. Ellerbrock, Daniel W. Konz, Marshall Watts

Patent number: 7552256Abstract: A communications system and method are provided for digitally connecting a plurality of data channels, such as sensors, actuators, and subsystems, to a controller using a network bus. The network device interface interprets commands and data received from the controller and polls the data channels in accordance with these commands. Specifically, the network device interface receives digital commands and data from the controller, and based on these commands and data, communicates with the data channels to either retrieve data in the case of a sensor or send data to activate an actuator. Data retrieved from the sensor is converted into digital signals and transmitted to the controller. Network device interfaces associated with different data channels can coordinate communications with the other interfaces based on either a transition in a command message sent by the bus controller or a synchronous clock signal.Type: GrantFiled: September 10, 2007Date of Patent: June 23, 2009Assignee: The Boeing CompanyInventors: Philip J.

Patent number: 7346719Abstract: The present invention provides systems, methods, and bus controllers (12) for monitoring an event of interest via a network bus (14) and creating an asynchronous event trigger on the network bus indicating that the event occurred. Importantly, the systems, methods, and bus controllers (12) of the present invention use either one or several network devices (16, 18) that are connected to the network bus (14) and monitor the occurrence of an event of interest. These network devices (16, 18) are configure through commands from the bus controller (12) to indicate on the network bus (14) typically by a pulse signal, when the event of interest has occurred. The indication from the network device (16, 18) that the event has occurred is used by the bus controller (12) and other network devices (16, 18, 20) on the network bus (14) to configure timing for commands or to perform desired actions in synchronization with the occurrence of the event of interest.Type: GrantFiled: April 26, 2002Date of Patent: March 18, 2008Assignee: The Boeing CompanyInventors: Philip J.
