Patent number: 10203964Abstract: An external controller module is configured for electrically coupling a mobile device to the one or more peripheral devices. The external controller module includes an interface port for coupling to a communication port of the mobile device and a number of interface ports for coupling the external controller module to respective peripheral devices. The controller module operating system includes device driver program code for facilitating electrical communication between the peripheral device and the mobile device without installing the device driver program code on the mobile device.Type: GrantFiled: August 25, 2017Date of Patent: February 12, 2019Assignee: Raytheon CompanyInventors: Darryn A. Johnnie, Andy D. Ngo, Stephen H. Kim

Patent number: 8175101Abstract: In one aspect, a method to multicast in a network includes determining using a processor a least amount of relay nodes for use in multicasting a message to nodes in the network by using a neighbor matrix of a source node used in Node Activation Multiple Access (NAMA) scheduling. The method may include designating a one-hop neighbor that exclusively accesses the two-hop neighbor of the source node as a relay node. The method may also include designating a one-hop neighbor of the source node with accessibility to a maximum number of two-hop neighbors of the source node as a relay node.Type: GrantFiled: July 24, 2009Date of Patent: May 8, 2012Assignee: Raytheon CompanyInventors: Sung I. Park, Darryn A. Johnnie

Patent number: 8014279Abstract: In one aspect, a method to schedule network communications includes transmitting a node identification associated with a first node joining a network over a first portion of control timeslots based on a first probability, detecting nodes in the network using a second portion of the control timeslots and receiving acknowledgments from at least one of the nodes in the network. The method also includes that if a ratio of a number of acknowledgments received to a number of the nodes in the network detected is greater than a predetermined percentage: transmitting control data over the first portion of the control timeslots based on a second probability associated with a number of the nodes detected and transmitting data over the second portion of the control timeslots based on a network schedule.Type: GrantFiled: August 22, 2007Date of Patent: September 6, 2011Assignee: Raytheon CompanyInventors: Sung Park, Darryn A.

Publication number: 20100265955Abstract: In one aspect, a method includes receiving a packet at a first node, the first node comprising a processor, determining, at the first node, whether a destination node of the packet is within a zone of the first node, using, at the first node, an on-demand routing protocol to route data from the first node to the destination node if the destination node is outside the zone of the first node and using a network topology, stored at the first node, to route the packet from the first node to the destination node if the destination node is within the zone of the first node.Type: ApplicationFiled: April 17, 2009Publication date: October 21, 2010Inventors: Sung I. Park, Darryn A. Johnnie

Patent number: 6871211Abstract: A network based medical telemetry system that uses, to the greatest extent possible, standard hardware and software components. The system allows clinicians using computers anywhere in a large hospital to view physiologic data from patients of the hospital. Each patient is fitted with a set of sensors that measure physiologic properties of the patient (e.g., EKG sensors). The sensors are connected to a transmitter that relays the physiologic data to a central server. The central server comprises a WEB server that supplies basic patient data such as the patient's name and medical history. The central server also comprises a waveform server which supplies the physiologic data, in real-time or near real-time. Workstation, used by a clinician receives the basic patient data from the Web server and the physiologic data from the waveform server, and produces a combined display. The combined display is continuously updated, showing, for example, the patient's EKG.Type: GrantFiled: March 27, 2001Date of Patent: March 22, 2005Assignee: GE Medical Systems Information Technologies, Inc.Inventors: Scott Labounty, David R. Clark, Darryn A. Johnnie
