Abstract: The present disclosure provides electroporation cartridges for single use electroporation as well as electroporation cartridges for automated batch processing, electroporation instruments and systems and methods of electroporation using these devices and systems. In some embodiments, electroporation cartridges comprise an electroporation chamber defined by an elongate body, a first electrode at a proximal end and a second electrode at a distal end of a chamber. Electroporation systems of the disclosure include one or more components including a pulse generator, compartments for placing either flow-through or single use electroporation cartridges, components for storage of cells, cooling and pre-cooling mechanisms, removably insertable modular casings having compartments for holding and arranging electroporation system and reagent components, one or more pumps for moving sample through the system, and processors and controllers.

Abstract: A hybrid antenna structure allows the antenna to be used internally or mostly internally in a portable radio communication device operating in the VHF range. The hybrid antenna structure includes a switching circuit that connects an RF circuit to one of several points along the length of a wrapped conductor element, depending on the selected operating frequency. An inductive matching tail element is adjustably tuned to match the selected tap point on the wrapped conductor for the selected operating frequency.

Abstract: A variable responsivity adaptive detector system (10) for a receiver protects a baseband amplifier from being overdriven and used to detect weak signals at the antenna (14). The RF detector system (10) includes an envelope detector (28) configured to receive an RF signal, and a power detector (20) sensing a magnitude of the received RF signal and providing a DC signal for biasing the envelope detector (28) to modify the magnitude of the received RF signal.

Abstract: An eyewear apparatus (100) has a first plurality of antennas (144, 142, 158) disposed thereon for transmitting a signal in a narrow beam (402), for example, with a directivity greater than 10 dBi, the signal comprising at least one of data and video. A microcomputer (126) is coupled to the first plurality of antennas for providing the signal thereto.
