Abstract: An electrical insulation displacement connector includes a body having at least one channel with an open top side configured for receipt of an insulated conductive core wire therein. A contact element is fixed in the body with a first insulation displacement end defined by opposed blades oriented across the channel, and a second end extending from a bottom surface of the body and configured for electrical contact with a PCB. The body includes retaining structure extending into the channel at a location relative to a depth of the blades within the channel such that the insulation portion of a wire inserted into the channel and pressed down into the first end of the contact element is pushed below the retaining structure, thereby preventing the wire from being inadvertently pulled out from the first end of the contact.

Abstract: A shorting clip terminal connector assembly electrically shorts together terminals in a first connector body dependent on connection status of a first and a second connector body. A shorting clip terminal disposed in a shorting clip terminal cavity in the first connector body receives a protrusion disposed on the second connector body. When the second connector body is mated with the first connector body, the protrusion engages a lift element of the shorting clip terminal in the shorting clip terminal cavity thereon and urges the lift element to lift contact elements of the shorting clip terminal away from the terminals in the shorting clip terminal cavity enabling insertion of protrusion side walls intermediate the contact elements and the terminals in the shorting clip terminal cavity. The contact elements of the shorting clip terminal do not make electrical contact with the terminals and the protrusion side walls further shield the contact elements from making electrical contact with the terminals.

Abstract: An electronic ballast has control circuitry to operate a gas discharge lamp in both full and dimmed illumination modes. The electronic ballast also includes a full power circuit having a power control coupled to the dimming controller output to receive the dimming controller signal, a filament heating circuit having a heating input coupled to a reduced power circuit to receive a reduced power signal and a heating output that can couple to the filaments of one or more lamps. When the full power circuit receives the dimming controller signal, via the power control, and the dimming controller signal is not in the dimming request range (i.e. the full illumination mode has been selected), the full power circuit generates a full power signal capable of driving/operating the lamp(s) in the full illumination mode. When the reduced power signal is present, the filament heating circuit generates and provides a filament heating signal to the filaments, via the heating output.

Abstract: A vertical wind-driven electricity generation device is described, which utilizes a unique segmented Savonius rotor and which is easily handled, transported, assembled and maintained, even by a single person. The blades of the rotor are segmented into a plurality of modest size blade pair segments, each of which comprises two (or optionally, three or four) low height, helically curved blade portions.
