Abstract: A method of improving the performance of a traveling wave field-effect transistor operated at frequencies in the microwave range or above the microwave range comprising the steps of forming a depletion region beneath a gate electrode wherein, in a plane transverse to the direction of signal propagation, a depletion region edge has a first end portion located between the gate electrode and a drain electrode and a second end portion located between the gate electrode and a source electrode; and separating the depletion region edge from the drain electrode. Further improvements in the operation of the TWFET include adjusting the first end portion of the depletion region edge to be closer to the gate electrode relative to the distance between the second end portion of the depletion region edge and the gate electrode, controlling an effective conductivity of a semiconductor of the traveling-wave field effect transistor, and setting the length of the gate electrode at substantially 1.0 micron.

Abstract: A ball grid array socket with rows of electrical contacts that extend through holes in a plate. The arrangement of the holes and the electrical contacts provides an entry hole. The contacts are arranged with ends that are cupped to mate with the side and top of the ball contacts of the ball grid array package. The contact surface of the ball grid array package is vertically inserted without any interfering structure. The plate is spring loaded is such a way that the plate is driven parallel to the plane of the ball contacts in a manner that reduces the entry hole opening. This reduced entry opening is arranged and constructed such that with a ball contact insert therein electrical conductivity is provided between the ball contact and the electrical contact, and further where the cupped ends of the electrical contact retain the ball within the hole. The edges of the hole and the top of the cupped electrical contact are chamfered to mate with the curved sides of the ball contact.

The uppermost leg ends in a substantially perpendicularly disposed locking tab and the lowermost leg has a variety of locking arrangements, one of which permits the locking clip to be locked in two locking positions. In one locking position the integrated circuit package is held securely in place while in the other locking position the integrated circuit package may be inserted or removed from the carrier.

Abstract: A golf information and management system utilizing the Global Positioning System, a satellite based, radio navigation system where clocks signals are transmitted. This satellite system provides at least four satellites (2) "in view" at all time. A golf cart (12) or player receives the signals from the four satellites, compares the clocked signals and an on-board computer reads the clocked signals and determines the position, in three dimension, of the receivers (velocity of the receivers is also available). There is a fixed base location (8) on the golf course that also receives the satellite signals and transmits a differential correction signal, via another channel, to the golf cart or player, where the computer determines the position of the cart or player to within a yard. The computer may be pre-loaded with golf course information, such as pin position, hazard positions, etc.

Abstract: An aligning socket for an IC that provides an aligning bar that aligns and secures IC leads to the corresponding socket contacts (6), and where the bar has extensions or ears (42) that extend toward the row of IC leads (38). The ears have chamfered edges that, as the bar is forced toward the IC leads, guide the IC leads to mate with the socket contacts. For more fragile gull-winged leads, a rail 18 is provided to support the under side of the leads and the alignment bar ears are designed to fit over the ends of the rail. When the bar and socket contacts are forced toward the IC leads, the bar ears overlap the ends of the rail and force any mis-aligned IC leads to move such that alignment of the leads and the socket contacts is achieved.

Abstract: A device and method of suturing closed an opening and ligating a vessel or duct comprising removable tissue puncturing means (22) or vessel surrounding means establishing a continuous channel (24) through said tissue or around said vessel from each side. A completed channel (24) is formed and suture material (26) is threaded through the channel making a complete loop. The thread is secured at an anvil (30) independent from said puncturing/surrounding means. The puncturing/surrounding means is retracted leaving the thread, which is then tensioned closing the opening or occluding the vessel. The suture thread is secured and cut, forming a closed loop with overlapping ends. An energy transmitting device (38) melts the suture thread ends together forming a weld. The anvil (30) is removed leaving a knot-free completed stitch or ligature.
