Patent number: 9000787Abstract: A method and a system for three-phase detection of a three-phase electric device are provided. The system includes a testing circuit and a comparison module. The testing circuit generates two reference voltages by using the three phase voltages of the three-phase electric device. The two reference voltages are the first and second phase voltages with reference to the third phase voltage, respectively. Three-phase detection is performed by comparing the two reference voltages for a determined number of times. After testing is completed, the testing circuit is switched off by the comparison module, to save power.Type: GrantFiled: December 21, 2007Date of Patent: April 7, 2015Assignee: Carrier CorporationInventors: Brian Inman, Robert P. Dolan, Anthony G. Russo, Steven M. Palermo

Patent number: 7294052Abstract: In an air handling unit for discharging a flow of air into the surrounding ambient, having a series of horizontal louvers and a series of vertical louvers mounted in the discharge flow. A first multi-phase stepper motor is arranged to step the horizontal louvers to deflect the air flow in a vertical direction and a second multi-phase stepper motor is arranged to step vertical louvers to deflect the flow in a transverse direction. A controller is programmed to alternately apply power from a single power source to each of the motors during each phase to step each motor in equal increments during each phase.Type: GrantFiled: August 2, 2004Date of Patent: November 13, 2007Assignee: Carrier CorporationInventors: Robert P.

Patent number: 6794264Abstract: The present invention provides a method for creation of high quality semiconductor-on-insulator structures, e.g., silicon-on-insulator structures, using implantation of sub-stoichiometric doses of oxygen at multiple energies. The method employs sequential steps of ion implantation and high temperature annealing to produce structures with a top silicon layer having a thickness ranging from 10-250 nm and a buried oxide layer having a thickness 30-300 nm. The buried oxide layer has a breakdown field greater than 5 MV/cm. Further, the density of silicon inclusions in the BOX region is less than 2×107 cm−2. The process of the invention can be used to create an entire SOI wafer, or be used to create patterned SOI, regions where SOI regions are integrated with non-SOI regions.Type: GrantFiled: April 30, 2002Date of Patent: September 21, 2004Assignee: Ibis Technology CorporationInventors: Robert P. Dolan, Bernhardt F. Cordts, III, Maria J. Anc, Micahel L. Alles

Patent number: 6593173Abstract: Methods of producing buried insulating layers in semiconductor substrates are disclosed whereby a dose of selected ions is implanted into a substrate to form a buried precursor layer below an upper layer of the substrate, followed by oxidation of the substrate in an atmosphere having a selected oxygen concentration to form an oxide surface layer. The oxidation is performed at a temperature and for a time duration such that the formation of the oxide layer causes the injection of a controlled number of atoms of the substrate from a region proximate to an interface between the newly formed oxide layer and the substrate into the upper regions of the substrate to reduce strain. A high temperature annealing step is then performed to produce the insulating layer within the precursor layer.Type: GrantFiled: November 28, 2000Date of Patent: July 15, 2003Assignee: Ibis Technology CorporationInventors: Maria J. Anc, Robert P. Dolan

Patent number: 6535138Abstract: A system for verifying the operability of one or more HVAC devices in a communication network includes a network control device that sends a particular type of message to the HVAC devices. Each HVAC device receiving the message will initiate a clearly visible display on the HVAC device if the message is appropriately processed within the receiving HVAC device. Each HVAC device may be visually checked to confirm that it is in fact responding to the message from the network control device.Type: GrantFiled: October 25, 1996Date of Patent: March 18, 2003Assignee: Carrier CorporationInventors: Robert P.

Patent number: 6448896Abstract: An electronic system for monitoring the condition of the filter in an HVAC unit includes a controller which issues at least one command to a circuit for the motor of the fan producing airflow through the filter. The command to the driver circuit is associated with a desired run speed for the fan. The controller is operative to compute the speed of the fan following issuance of the command to the motor drive circuit. This computed speed is compared to a predetermined fan speed that would normally occur when the filter is dirty. The electronic system is operative to generate a warning in the event that the computed fan speed does not compare favorably with the predetermined fan speed.Type: GrantFiled: August 24, 2001Date of Patent: September 10, 2002Assignee: Carrier CorporationInventors: Roger S. Bankus, Thomas L. DeWolf, Robert P. Dolan, Brian D. Inman
