Publication number: 20200256881Abstract: Sensors employing bulk acoustic wave (BAW) resonators are used to assay characteristics of blood. The BAW sensors may be used to sense viscosity of a sample comprising blood to determine coagulation properties of the blood. The viscosity of the blood may be evaluated in the presence of agents that inhibit coagulation or that promote coagulation. The change in viscosity of the sample in the presence of such agents may provide information regarding whether the blood suffers from a coagulation disorder.Type: ApplicationFiled: July 25, 2017Publication date: August 13, 2020Inventors: Florian Bell, Bruce Murdock

Patent number: 4707845Abstract: A touch panel has panel scanning signals selectively applied to the four sides of a touch sensing surface of the panel so as to establish alternating current voltage gradients in desired directions across the touch sensing surface. When the panel is touched, touch signals result and are utilized by a touch location circuit in determining the location of touch. The impedence touch current resulting from a user's touch may also be determined and used. The touch panel circuit automatically compensates for any variations in touch signals which occur when the touch panel is untouched and automatically nulls the touch signals under such circumstances to enhance the accuracy of touch location determination.Type: GrantFiled: August 26, 1986Date of Patent: November 17, 1987Assignee: Tektronix, Inc.Inventors: Philip T. Krein, Robert D. Meadows, Bruce Murdock, Daniel G. Teichmer

Patent number: 4698460Abstract: A touch panel has panel scanning signals selectively applied to the four sides of a touch sensing surface of the panel so as to establish alternating current voltage gradients in desired directions across the touch sensing surface. When the panel is touched, touch signals or currents result and are utilized by a touch location circuit in determining the location of touch. The impedance touch current resulting from a user's touch may also be determined and used. The touch panel circuit automatically compensates for changes in impedance touch current, such as result when users touch the panel with ungloved and gloved fingers. An analog multiplier is included in the touch location circuit to improve noise rejection. Auto nulling and automatic frequency adjustment is included in the touch panel device, together with overcurrent protection circuitry.Type: GrantFiled: August 26, 1986Date of Patent: October 6, 1987Assignee: Tektronix, Inc.Inventors: Philip T.

When the panel is touched, touch signals result and are utilized by a touch location circuit in determining the location of touch. The impedence touch current resulting from a user's touch may also be determined and used. The touch panel circuit automatically adjusts the frequency of the applied panel signals to shift this frequency away from fixed frequency interference spectra, such as due to cathode-ray tube flyback signals, in the environment in which the touch panel is used. The touch location thereby minimizes the effects of such spectra on touch location determinations.Type: GrantFiled: August 26, 1986Date of Patent: October 6, 1987Assignee: Tektronix, Inc.Inventors: Robert D. Meadows, Philip T. Krein, Bruce Murdock
