Patent number: 8441947Abstract: A packet controller for simultaneous processing of data packets transmitted via a plurality of communication channels includes a plurality of inputs to receive a respective plurality of signals, such that each of the plurality of signals is indicative of a presence of a data packet on a respective one of the plurality of communication channels, a clock source to supply a periodic clock signal, a plurality of independent processing modules coupled to the respective plurality of inputs to simultaneously process the plurality of signals, such that each of the plurality of independent processing modules implements a respective state machine driven by the periodic clock signal to process the respective signal independently of every other one of the plurality of processing modules, and an output to transmit an output signal indicative of a presence of at least one data packet on one or more of the plurality of communication channels.Type: GrantFiled: June 23, 2009Date of Patent: May 14, 2013Assignee: Hart Communication FoundationInventors: Wallace A. Pratt, Jr., Chuck Middleton, Mark M. Okamura, Daraius Hathiram, Ronald E. Ham

Publication number: 20070090920Abstract: An apparatus and method for controlling access to remotely located equipment are disclosed. The method includes receiving a request at an access control module (ACM) from a host controller to provide a serial number associated with the ACM and communicating the serial number to the host controller. In response to communicating the serial number to the host controller, the ACM receives a calculated unique key from the host controller and compares the calculated unique key with a unique key stored in a microprocessor associated with the ACM. If the calculated unique key matches the stored unique key, the ACM generates an actuation signal and communicates the actuation signal to a fail-safe switch assembly in order to activate at least one component of an electronic locking structure.Type: ApplicationFiled: March 23, 2006Publication date: April 26, 2007Inventors: James Canter, Daraius Hathiram

Patent number: 7050906Abstract: A method, computer program product and system for monitoring and locating an object using secure communications without relying on GPS. A monitoring device may activate a monitored unit (unit monitored by monitoring device) by transmitting a seed of an algorithm and a time synchronization to the monitored unit. The seed and time synchronization may be used in conjunction with an algorithm, e.g., frequency hopping table, stored in both the monitoring device and the monitored unit, to allow both the monitoring device and the monitored unit to communicate with one another at a uniquely synchronized time and frequency thereby making it more difficult for a third party to locate the monitored unit. An alert may be generated when the monitored unit is located beyond a predetermined zone. The monitored unit may be located by activating a directional antenna in conjunction with a digital compass on the monitoring device.Type: GrantFiled: June 10, 2004Date of Patent: May 23, 2006Assignee: Bluespan Inc.Inventors: Daraius Hathiram, Bruce Cummings, Nicholas Anderson, Ronald E.

Patent number: 5180896Abstract: The heating of blood or other medical fluids supplied to a patient is provided by a system and method of feedback control. The temperature of the blood is sensed by receiving infrared energy from the medical fluid as it flows within a sterile and disposable tube from a fluid source to the patient. Feedback control stabilizes the temperature at a desired value. A second sensor may optionally be used to determine if the fluid is too hot within the microwave device itself. The disposable tube has at least one window or thin membrane portion which allows infrared radiation to pass therethrough in order to be sensed by the sensor. One arrangement of the present invention uses a microprocessor with adaptive control to provide precise and accurate control of the temperature of the medical fluid.Type: GrantFiled: October 11, 1990Date of Patent: January 19, 1993Assignee: University of FloridaInventors: Gordon L. Gibby, Samsun Lampotang, Daraius Hathiram, Nikolaus Gravenstein
