Floating electricity production unit

Abstract: Electricity is produced by harvesting energy from flowing water, which does not harm the environment and which does not consume natural resources. A paddle wheel is stationarily positioned to penetrate the surface of a body of water. Preferably, a plurality of paddle wheels are deployed on a single floating platform to optimize the transfer of the energy contained in the flow of water passing the floating platform. Each paddle wheel is geared to rapidly rotate a generator axle of an electricity generator of the type conventionally deployed for wind turbines on “wind farms”. Preferably, each paddle wheel powers a plurality of electricity generators. Structure is provided to compensate for variations in flow rates in the body of water to intensify a flow of the water and to vary a depth of penetration of the paddle wheel into the water.

High current capacity semiconductor device housing

Abstract: A semiconductor device package is provided which can accommodate currents larger than those of similarly sized standard device packages such as the “TO-247” package. Higher currents are accommodated by allowing a larger semiconductor die to be mounted on the device's lead frame than can be mounted on a similarly sized standard package. An improved mold clamping area is also provided which reduces the area from which damaging moisture can enter the molded package and increases the distance required for moisture to contact the die. Clip arrangements are also provided to mount the device package to a circuit board or heat sink, thereby allowing the increased operating temperatures associated with the increased operating currents to be efficiently dissipated. The semiconductor device package has a lead frame having a large area paddle section and at least one leg extending therefrom, the lead frame being of substantially constant thickness, and the paddle section being continuous and free of openings therethrough. A semiconductor die is mounted to the paddle section of the lead frame, the semiconductor die occupying substantially all of the surface area of a side of the paddle section upon which the semiconductor die is mounted. The full surface of the die and at least the side of the paddle section upon which the semiconductor die is mounted are covered by a common and uninterrupted mold housing.

Switch apparatus for use in vehicles

Abstract: A vehicle switch apparatus for increasing space for other switches and ensuring operation of a switch when the switch must be felt for in order to be operated. The vehicle switch apparatus includes a paddle that has a front surface facing the driver and a rear surface opposite to the front surface. A push switch is arranged near the rear surface of the paddle and includes an operation portion operated by the driver. The paddle has a window for enabling the driver to visually check operation of the operation portion.

Apparatus for holding and feeding product

Abstract: Apparatus for holding and feeding product includes a) a tray having a front end, b) a sidewall clip, carried by a first extremity of a sidewall, attached to the front end of the tray, c) a paddle clip attached to the front end of the tray, d) a third elongate abutment clip, carried by an abutment, attached to the first and paddle clips, e) a paddle mounted to the tray for reciprocal movement in opposition to the abutment, and f) a spring coupling the paddle clip to the paddle and biasing the paddle toward the abutment.

Medical lead and method

Abstract: A medical lead for electrical stimulation or sensing. The medical lead has a generally flat paddle on the distal end of the lead body. An electrode array is provided on the paddle. The electrode array having directional electrical field properties relative to the first and major surfaces of the paddle (e.g., the electrodes are exposed through only one of the major surfaces). An orientation marker for determining orientation of the lead, with the orientation marking including fluoroscopically viewable material.
