Our clients include multinational conglomerates, high tech medical device companies, pharmaceutical companies, health care management companies, instrumentation companies, universities, and other private and publicly held companies. Our clientele have been acquired in mergers and acquisitions, have licensed or been granted licenses to complex electrical technologies, or have monetized their intellectual property in other exits.
Our professionals in the electrical patents group hold degrees in Electrical Engineering, Computer Engineering, and Physics, and offer over 60 years of combined experience.
An amplifier circuit includes a input point, an output point, and an amplifying path from the input point to the output point. The amplifying path includes a first switch and an amplifier in series with the first switch. The first switch includes a first transistor having a first gate, a first source, and a first drain, the first gate coupled to a control point. The first source or drain is coupled to the signal input point and the other is coupled to the amplifier. The amplifier includes a second transistor having a second gate, a second source, and a second drain. The second gate is coupled to the second switch in the signal amplifying path. The second source or drain is coupled to the signal output point. A third transistor may be coupled to the signal output point through the second transistor in a cascade amplifying configuration.
An illuminated assembly includes a substrate that is rigid so as to maintain a shape, the substrate having a first terminal surface and a second terminal surface. The assembly includes at least one channel defined into the substrate, the at least one channel having: an exposed portion defined on the first terminal surface of the substrate to define an indicia for display, a base portion defined between the first and second terminal surfaces of the substrate, and two channel walls extending from the exposed portion to the base portion. The assembly includes at least one light source between the exposed portion and the base portion of the at least one channel. The assembly includes a compound defined in an intermediate portion of the at least one channel, the intermediate portion extending from the at least one light source to the two channel walls, the exposed portion, and the base portion.
A novel sample holder for specimen support devices for insertion in electron microscopes. The novel sample holder of the invention allows for the introduction of gases or liquids to specimens for in situ imaging, as well as electrical contacts for electrochemical or thermal experiments.
A fluid pressure actuated device for establishing electrical contact includes a substrate defining a chamber, a flexible membrane having a first side facing a first direction away from the substrate and a second side facing into the chamber in a second direction opposite the first direction, and an electrically conducting contactor mounted on the first side of the flexible membrane. The flexible membrane extends and withdraws moving the electrically conducting contactor in the first direction and second direction respectively when fluid pressure is increased and decreased in the chamber. The flexible membrane includes at least two concentric frustum portions that narrow in opposite directions, including a central frustum portion and a second frustum portion that encircles the central frustum portion. Multiple chambers may be maintained in pressure equilibrium by at least one channel for the concurrent extension of multiple membranes and contactors.
