Patent number: 6916656Abstract: An object of the invention is to provide a method of treating biological cells prior to subjecting the biological cells to cell fusion pulses which includes the step of treating the biological cells with pre-fusion electric field waveforms which change amplitude in a non-linear way with respect to time, such that the biological cells are first aligned with a relatively low amplitude, long duration pre-fusion electric field waveform and then compressed with a relatively high amplitude, short duration pre-fusion electric field waveform resulting in increased cell membrane contact prior to being subjected to cell fusion. The non-linear pre-fusion electric field waveforms can change in a stepped way, in a continuous way, in a sigmoidal way, with step-wise increasing waveforms in adjacent steps, with step-wise increasing waveforms in non-adjacent steps, and in accordance with non-linear algorithms.Type: GrantFiled: April 5, 2002Date of Patent: July 12, 2005Assignee: Cyto Pulse Sciences, Inc.Inventors: Richard E.

Patent number: 6907244Abstract: Briefly, the present invention provides a dynamic channel re-assignment capability between mobile units, base stations and sectors within base station coverage areas. The wireless devices used in the present invention may include impulse radio communication devices such as, for example ultra-wideband radio (also known as digital pulse wireless) communication devices. Ultra-wideband bandwidth and channel allocation can be effectively managed, even though link quality generally deteriorates near the outer boundary of the base station. By maintaining dual communications with an adjoining base station, the present invention reduces the bit error rate and maintains signal strength (e.g., RF signal strength). This procedure is termed a “soft-handoff”.Type: GrantFiled: March 12, 2001Date of Patent: June 14, 2005Assignee: Pulse-LINK, Inc.Inventors: John H. Santhoff, Donald W. Jolly, Rodolfo T. Arrieta

Patent number: 6900710Abstract: An ultrafast sampling system includes an interposer and a sampler that include series of Schottky diodes configured with a non-parallel waveguide to form shocklines or nonlinear transmission line (NLTLs) that produce a differential strobe pulse. The shocklines are defined by non-parallel conductors that are configured as, for example, triangular, dentate, arcuate, or other shapes, or as conductors that have edges that are triangular, dentate, arcuate, or the like. The conductors are defined with respect to a substrate, and are airbridged so that at least some portions of the conductors are displaced from the substrate to reduce waveguide capacitance. Electrical connection to the sampler is made with airline having a inner conductor that is deformable to contact an input pad defined on the sampler.Type: GrantFiled: November 2, 2001Date of Patent: May 31, 2005Assignee: Picosecond Pulse LabsInventors: Agoston Agoston, John Ebner, Steven Pepper, David Pratt

Patent number: 6877211Abstract: A method of making a microelectronic package. The advanced microelectronic component package incorporates a specially shaped base element which holds and electrically separates the individual conductors associated with the microelectronic component(s) so that the individual conductors may be bonded to external package leads and other conductors within the package. In a first embodiment, jacketed, insulated wire is used as one winding of a toroidal transformer, while unjacketed insulated wire is used as another winding. The jacketing is stripped from the first winding and the exposed conductors are routed into channels along the sides of the base element. The unjacketed conductors are also routed into the same channels, where both conductors are bonded to the external package leads. Raised elements along the sides of the base provide the required electrical separation between the conductors during both manufacture and operation. A method of manufacturing the improved microelectronic package is also disclosed.Type: GrantFiled: February 27, 2001Date of Patent: April 12, 2005Assignee: Pulse Engineering, Inc.Inventor: Russell Lee Machado
