Patent number: 7049926Abstract: Disclosed is a variable voltage protection device for electronic devices which in one aspect comprises a thin layer of neat dielectric polymer or glass positioned between a ground plane and an electrical conductor for overvoltage protection, wherein the neat polymer or glass layer does not include the presence of conductive or semiconductive particles. Also disclosed is the combination of the neat dielectric polymer or glass thin layer positioned on a conventional variable voltage protection material comprising a binder containing conductive or semiconductive particles. A multi-layer variable voltage protection component is disclosed comprising three layers of overvoltage protection material wherein the outer two layers contain a lower percentage of conductive or semiconductive particles and wherein the inner layer contains a higher percentage of conductive or semiconductive particles.Type: GrantFiled: November 6, 2003Date of Patent: May 23, 2006Assignee: SurgX CorporationInventors: Karen P. Shrier, Gerald R. Behling, James B. Intrater, Kailash C. Joshi, William W. Alston, Jr.

Patent number: 6606992Abstract: Systems and methods are provided for aerosolizing a pharmaceutical formulation. According to one method, respiratory gases are prevented from flowing to the lungs when attempting to inhale. Then, respiratory gases are abruptly permitted to flow to the lungs. The flow of respiratory gases may then be used to extract a pharmaceutical formulation from a receptacle and to place the pharmaceutical formulation within the flow of respiratory gases to form an aerosol.Type: GrantFiled: May 30, 2000Date of Patent: August 19, 2003Assignee: Nektar TherapeuticsInventors: Carlos Schuler, Steve Paboojian, Derrick J. Tuttle, Adrian E. Smith, Dennis R. Rasmussen, Aneesh Bakshi, Andrew Clark, Brian R. S. Ward, William W. Alston, Jr., Kevin S. Nason

Patent number: 6542065Abstract: A variable voltage protection component in accordance with this invention comprises a reinforcing layer of insulating material having a substantially constant thickness embedded in a voltage variable material. With this configuration, the reinforcing layer defines a uniform thickness for the variable voltage protection component that is resist to compressive forces that may cause a reduction in the clamp voltage or a short in the voltage variable material. In addition, the variable voltage protection component can be attached to a compressible ground plane to form a variable voltage protection device. Methods are provided for making the variable voltage protection component and device.Type: GrantFiled: April 10, 2001Date of Patent: April 1, 2003Assignee: SurgX CorporationInventors: Karen P. Shrier, Gerald R. Behling, Kailash C. Joshi, William W. Alston, Jr.

Patent number: 4502489Abstract: Apparatus is disclosed for measuring an athlete's auditory reaction time, and for training an athlete to reduce his auditory reaction time in response to an auditory stimulus used to initiate an athletic event. The apparatus automatically provides a sequence of variable time delays followed by auditory stimuli which stimulates the sequence and auditory quality of the preparatory commands used to initiate an athletic event. The apparatus further provides means for measuring and indicating the athlete's auditory reaction time in response to the auditory stimulus which represents the "Go" signal of the athletic event.Type: GrantFiled: September 29, 1982Date of Patent: March 5, 1985Assignee: Audostart CorporationInventor: William W. Alston, Jr.
