Patent number: 11920843Abstract: A chiller includes an evaporator, a compressor including a prime mover, a first pressure sensor that detects a first pressure in the evaporator, a second pressure sensor that detects a second pressure in a condenser, and a controller. The controller determines a predicted energy level of the compressor based on the first pressure and the second pressure, the predicted energy level associated with liquid droplet flow into the compressor, compares the predicted energy level to an operating energy level, and modifies the at least one of the input power and the input current to the prime mover based on the comparison satisfying a modification condition.Type: GrantFiled: November 14, 2022Date of Patent: March 5, 2024Assignee: Johnson Controls Tyco IP Holdings LLPInventors: Shimin Sheng, Xiuping Su, Shenglong Wang, Curtis Christian Crane, Mark Robinson Bodell, II, Justin Patrick Kauffman

Publication number: 20230040084Abstract: Implementations described herein relate to methods, systems, and computer-readable media to automatically answer a call. In some implementations, a method includes receiving a call from a caller device at a client device. The method further includes determining, based on an identifier associated with the call, whether the call matches auto answer criteria, and yin response to determining that the call matches the auto answer criteria, answering the call without user input and without alerting a user of the client device. The method further includes generating a call embedding for the call based on received audio of the call, comparing the call embedding with spam embeddings to determine whether the call is a spam call, and in response to determining that the call is a spam call, terminating the call.Type: ApplicationFiled: November 18, 2020Publication date: February 9, 2023Applicant: Google LLCInventors: Joseph Joseph CHERUKARA, Paul DUNLOP, Hanfu ZHANG, Milo SREDKOV, Aditi BHARGAVA, Mariia SANDRIKOVA, Gustav SENNTON, Usman ABDULLAH, Andres CALVO, Brandon MAXWELL, Rebecca Gisoo Park CHIOU, Curtis ROBINSON, Yale THOMAS, Richard LEDLEY, Abhijith SHASTRY, Ayesha KHWAJA, Xiansha JIN, Wei Li WANG, Subash GUTALA, Shashank GOYAL

Patent number: 9001530Abstract: An integrated circuit may include a signal generator configured to generate a switching signal and a switching unit coupled to the signal generator. The switching unit may be configured to generate a pulsed current based on the switching signal using a first voltage. The integrated circuit may also include an inductive unit coupled to the switching unit. The inductive unit may be configured to receive the pulsed current and to generate a second voltage different from the first voltage.Type: GrantFiled: June 19, 2013Date of Patent: April 7, 2015Assignee: Finisar CorporationInventors: Henry M. Daghighian, Curtis Robinson, Lucy Hosking

Publication number: 20050077950Abstract: A negative charge pump is disclosed. The negative charge pump may be used to drive white LEDs in one application. The negative charge pump uses predominantly n-channel transistor switches that enables a smaller integrated circuit area. Further, a soft start mechanism is used in starting the charge pump.Type: ApplicationFiled: October 14, 2003Publication date: April 14, 2005Inventor: Curtis Robinson

Publication number: 20050017700Abstract: A method of controlling the output voltage of a voltage regulator that uses a transimpedance block is disclosed. The method comprises measuring the voltage representative current of the output and comparing the voltage representative current to a reference current. Finally, the charging process is stopped if the voltage representative current of the secondary winding is substantially the same as the reference current.Type: ApplicationFiled: July 24, 2003Publication date: January 27, 2005Inventor: Curtis Robinson

Patent number: 6556249Abstract: A method and apparatus for compensating for time base or phase errors in video and audio signals that are separately stored or processed. A ring oscillator provides a plurality of clock signals, each having a same frequency and slightly different phase. Each of the clock signals is applied to a multiplexor for allowing an appropriate one of the clock signals to be selected. By selecting appropriate ones of the clock signals in a sequence, the frequency and phase of an output clock signal formed by the multiplexor can be continuously and precisely controlled. Sync pulses separated from a video signal having a varying time base are applied to a video timing generator circuit which generates a series of digital values representative of timing differences between an expected occurrence of a sync pulse and an actual occurrence of the sync pulse. A phase accumulator accumulates the digital values over time for generating appropriate addresses for the multiplexor.Type: GrantFiled: September 7, 1999Date of Patent: April 29, 2003Assignee: Fairchild Semiconductors, Inc.Inventors: Gerard E. Taylor, Curtis Robinson, David W. Ritter, Robert Zucker

Patent number: 6146792Abstract: Improved processes for laser thermal imaging and imaged laserable assemblages obtained using the improved processes of this invention are described. These improved processes operate effectively at high speeds and also afford high image densities and good durability of images present on receiver elements upon thermal imaging done in accordance with these improved processes. One application of the improved process provides a color filter element.Type: GrantFiled: January 13, 1999Date of Patent: November 14, 2000Assignee: E. I. du Pont de Nemours and CompanyInventors: Graciela Beatriz Blanchet-Fincher, Curtis Robinson Fincher, Jr.

Patent number: 5942649Abstract: Method for thermally decomposing addition polymers, such as polyolefins, into monomers and monomer fragments. Thermal decomposition occurs by the rapid heating of the addition polymer such that the polymer ceiling temperature is reached in a time period substantially equal to the thermal relaxation time of the polymer itself. Laser ablation, wherein the polymer is heated by very rapid nanosecond or microsecond pulses of ultraviolet or infrared laser beams, and flash pyrolysis are particularly useful techniques for accomplishing such rapid heating.Type: GrantFiled: December 18, 1997Date of Patent: August 24, 1999Assignee: E. I. du Pont de Nemours and CompanyInventors: Graciela Beatriz Blanchet-Fincher, Curtis Robinson Fincher, Jr.

Patent number: 5560627Abstract: A low-cost wheelchair that is formed from side members made from continuous, bent single pieces of tubing that is formed to create a loop, and crimped at the juncture where the loop is formed. An axle is mounted at the juncture of each loop, and a large rear wheel is mounted on each axle.Type: GrantFiled: November 16, 1993Date of Patent: October 1, 1996Assignee: Guardian Products, Inc.Inventors: Leonid Zatulovsky, Curtis A. Robinson, Sr., Robert W. Renolds, Jr., Robert Dingley, David St. George

Patent number: 5543697Abstract: A method and circuit for implementing a frequency lock loop circuit in a disk drive is disclosed. The circuit includes the motor control elements of a direct current motor plus a coarse counter, a fine counter, and a digital to analog converter. The coarse counter is used to count down from a programmed coarse count. The fine counter begins to count down from a fine count when the coarse counter reaches zero. The count in the fine counter, when a zero crossing occurs, represents the difference between the expected period and the actual period and is loaded into a digital to analog converter which converts the difference to an analog voltage which is used by the coil drive circuit to either speed up or slow down the motor. The digital to analog conversion may be realized by a charge pump circuit.Type: GrantFiled: October 27, 1994Date of Patent: August 6, 1996Assignee: SGS-Thomson Microelectronics, Inc.Inventors: Francesco Carobolante, Curtis Robinson
