Publication number: 20240099368Abstract: An electronic cigarette (“e-Cig”) may include functionality for monitoring and controlling the thermal properties of the e-Cig. The system and method described herein may monitor a temperature based on a resistor (i.e. hot wire) near the wick and model the thermal cycle of an e-Cig. The model can be used for controlling the temperature of the c-Cig and preventing burning. The temperature control may dictate optimal conditions for atomization and smoke generation in an e-Cig while avoiding hotspots and burning to the atomizer or cartomizer.Type: ApplicationFiled: November 28, 2023Publication date: March 28, 2024Applicant: Altria Client Services LLCInventors: Eyal PELEG, David COHEN, Harold BROOKS, Dorron LEVY

Publication number: 20080028350Abstract: A characterized cell library for EDA tools includes receiver model data that provides two or more capacitance values for a given receiver modeling situation (signal type and operating conditions). The receiver model can then use different capacitance values to generate different portions of the model receiver signal, thereby enabling more accurate matching of actual receiver signal timing characteristics. For example, a two-capacitance receiver model can be generated by using the first capacitance value to match the delay characteristics of an actual receiver, and by using the second capacitance (in light of the use of the first capacitance) to match the slew characteristics of that actual receiver. Because typical EDA timing analyses focus mainly on delay and slew (and not the detailed profile of circuit signals), a two-capacitance receiver model can provide a high degree of accuracy without significantly increasing cell library size and computational complexity.Type: ApplicationFiled: October 3, 2007Publication date: January 31, 2008Applicant: Synopsys, Inc.Inventor: Harold Levy

Publication number: 20070261010Abstract: A precharacterized cell library for EDA tools includes driver model data includes output current signals indexed by output voltages. The driver model can then generate a model output by interpolating the output current signals using the output voltage to generate an output current. The output current can then be used to generate an updated output voltage across a predetermined time increment. The output current signals can then be interpolated using the updated output voltage to generate a new output current, when can be used to update the output voltage once again across the next time increment. By repeating this process across a time frame for the model output signal, a model output current and output voltage signals can be generated that match the actual output current and voltage signals from a driver in a multi-driver system.Type: ApplicationFiled: July 17, 2007Publication date: November 8, 2007Applicant: Synopsys, Inc.Inventor: Harold Levy

Publication number: 20070083838Abstract: An enhanced library accessible by an EDA tool can include a base curve database and a plurality of curve data sets. Each curve data set refers to a standard cell having certain timing characteristics. To determine those timing characteristics, each curve data set identifies at least one base curve (in the base curve database) as well as a starting current, a peak current, a peak voltage, and a peak time. In one embodiment, each base curve can be normalized. The base curve(s), the starting current, peak current, peak voltage, and peak time can accurately model the functioning of the IC device, e.g. represented by an I(V) curve.Type: ApplicationFiled: October 6, 2005Publication date: April 12, 2007Applicant: Synopsys, Inc.Inventors: Xin Wang, Harold Levy, Michael Misheloff

Publication number: 20060095243Abstract: A method for generating a linear piecewise representation of a driver output current signal includes segmenting the driver output current signal such that an integral of each segment matches an actual voltage change in corresponding portion of an associated output voltage signal (within a desired tolerance). The beginning and ending current/time values for each segment can then be compiled into the piecewise linear representation of the driver output current signal. A method for generating a model driver output current signal includes conformally mapping first and second sets of precharacterization output current data based on a weighted average of the indexing parameter (e.g., input slew or output capacitance) values for the model driver output signal and the first and second sets of precharacterization data.Type: ApplicationFiled: October 29, 2004Publication date: May 4, 2006Applicant: Synopsys, Inc.Inventor: Harold Levy

Publication number: 20050039151Abstract: A system is provided for determining voltage at the output of a gate in an integrated circuit. The system locates a gate within the integrated circuit and looks up a set of output current waveforms as a function of time for different effective capacitances at the gate's output. The system applies each output current waveform to its corresponding effective capacitance to calculate a first set of output voltages and applies each output current waveform to a model of the net coupled to the output of the gate to calculate a second set of output voltages. For each time step in a series of time steps, the system selects an output current waveform for which a voltage in the first set of output voltage waveforms matches a voltage in the second set of output voltage waveforms. The system uses the selected output current waveform to determine the output voltage.Type: ApplicationFiled: August 11, 2003Publication date: February 17, 2005Inventor: Harold Levy

Patent number: 6090995Abstract: Synthetic surfaces such as surfaces of implantable prosthetic devices are modified to enhance their ability to support the growth, migration and attachment of epithelial cells. A surface modifier composition is covalently bound to the synthetic surface, and an epithelial cell-supporting coating is applied to the modified surface. The surface modifier composition may also include an epithelial cell-supporting material. The invention is particularly suited towards the modification of synthetic epikeratophakia lenses.Type: GrantFiled: February 28, 1997Date of Patent: July 18, 2000Assignee: Surmodics, Inc.Inventors: Cary Reich, Jeffrey Forsberg, Harold Levy, Jean Toner-Webb

Patent number: 4033538Abstract: The present invention is a support of the suspended type in a form specifically designed for use in drying drip dry apparel, wet clothing, and the like. It may be used to advantage in the bathroom, when it is suspended above the shower doors on the square beam of the shower enclosure, and it is made adjustable to fit all shower door beams which are of different widths. No installation is required and it is put on and taken off the shower door beam with ease, and does not interfere with the opening and closing of the shower doors, therefore it may be left on permanently. In changing from one shower door beam to another of different width the device is simply adjusted. It is completely collapsable as it comes all apart and breaks down to fit into a very minimum of luggage space when travelling. The device can be made of sheet metal wire, plastic, and other materials.Type: GrantFiled: September 20, 1976Date of Patent: July 5, 1977Inventor: Harold Levy
