Title: Method for attaching an antenna to a circuit board and article produced thereby
Inventor: MENDOZA RODOLFO
IPC: H01R24/50
Filed: 2000-07-31
Abstract: An electronic circuit assembly, comprising: a printed circuit board 10 having opposed top and bottom surfaces 12/14 and a circuit board edge 16 thereabout, a slot 18 formed in the circuit board edge (wherein the slot has two opposed longitudinal edges 20 and a transverse edge 22), and a plated through-hole 32 formed through the board adjacent the transverse edge 22; and a generally elongate antenna socket 46 having an outer surface 48 thereof, a female electrical connector 54 formed in an outboard end 52 thereof, and a finger 56 formed in and extending from an inboard end 50 thereof. The antenna socket 46 is disposed so as to rest within the slot 18 on the top circuit board surface 12 with the finger 56 extending through the plated through-hole 32. In a preferred embodiment, at least one first solder joint 58 on the bottom circuit board surface 14 connects a respective one of the longitudinal edges 20 of the slot with the adjacent outer surface 48 of the antenna socket 46, while a second solder joint 60 connects the finger 56 with the plated through-hole 32.

Inventor: RARD ROY
IPC: B63H23/10
Filed: 2000-08-09
Abstract: An improved rudder system and pedal system for use in a watercraft such as a kayak. The rudder assembly includes a rudder housing having a push rod operably linked to a rudder blade positioned in the housing. A rudder control cord passes through a fairlead located at the top of the push rod and terminates at the trailing edge of the rudder blade. Upon tensioning of the rudder cord, the push rod acts against a notch in the leading edge of the rudder blade, which causes rotation of the rudder blade in addition to the rotational force on the trailing edge of the rudder blade due to movement of the control cord. A feature of the rudder assembly is the incorporation of a spring element in the rudder blade that provides an extension bias to the rudder blade, and user selectable pre-loading thereof for varying the rotational bias. The pedal system includes a toe control pivotally attached to a foot brace that is slidingly located in a track. A rudder cable arrangement is deflected by rotation of the toe control along the length of the track, thereby permitting actuation of the rudder system independent of the location in the track of the pedal system. A feature of the pedal system is the incorporation of a lockable positioning rod connected to the foot brace at one end and extending past the aft end of the track so that a user can remotely position the foot brace and retain its position.  Another feature is the use of a trim control assembly to vary the length of cable between the foot brace and a mechanical ground, thereby permitting the user to remotely select the rudder blade trim, without having to modify the position of the control pedals.

Title: Method and device for recording real-time information
Inventor: WILSON PATRICIA ELIZABETH MCDO
IPC: G11B27/034
Filed: 1999-11-05
Abstract: A method and device for recording real time information on a record carrier, e.g. video on an optical disc. The information is arranged according to a recording format, e.g. DVD video, for being playable in standardized players. The information is subdivided into units and playback parameters for reproducing sequences of the units are included in the units. The format prescribes forward pointers to units that are located at a large distance from the unit which includes the forward pointers. However for home recording it is required that a recording is made in one pass, i.e. the video is to be recorded directly at its final location without a large buffer. So the device has a small buffer (30), and a processing unit (20, 28) for determining pointers to nearby units based on the buffer contents, while values for pointers pointing far forward are set arbitrarily, based on nearby units and/or default values indicating that the unit intended to be pointed to does not exist. Standard playback devices can still play the recorded material in trickplay modes with only minor deviations in the fast forward scanning speed.

Inventor: VANDERVEEN MICHAELA C
IPC: H04L12/56
Filed: 2001-01-10
Abstract: The penalties associated with relying on layer-4 to handle packets lost as a result of a handoff can be reduced by forwarding, in response to a handoff request from a first base station to a second base station, at least one layer-2 frame of a layer-3 packet destined to/from the wireless terminal that has been passed down from layer-3 to layer-2, and so is indicated to have been transmitted at layer- 3 even though not all of the layer-2 frames of the layer-3 packet have actually been transmitted. In one embodiment of the invention, each of the at least one layer-2 frames may be encapsulated together in a special layer-3 packet that is transferred from the first base to the second base station in the usual manner of inter- base- station communication. Advantageously, packets are not lost at layer-4 due to handoffs. Thus, layer-4 retransmissions are not required, and so delays in the network are reduced. Furthermore, if only the layer-2 frames that were not transmitted over the air to the wireless terminal by the first base station are transferred to the second base station, a savings may be had in use of the air interface.

One embodiment combines first and second thermal arched beams having medial portions arched in opposed nonparallel directions with respect to the plane defined by the underlying substrate by even greater amounts. In response to thermal actuation, the medial portions thereof arch in opposite nonparallel directions with respect to the underlyi ng substrate, thereby altering the separation of the medial portions from the underlying substrate. Hybrid thermally actuated structures are provided that  combine arrays capable of moving in-plane and out of plane, such that motion  in all three dimensions may be achieved in response to selective thermal actuation.

Patent CA-2345089-A1 (CA)
Inventor: KAUFMAN RALPH
IPC: H04W88/02
Filed: 1999-09-22
Abstract: A power amplifier circuit arrangement including a driver amplifier, a switch, an amplifier path having a band pass filter and a power amplifier, and a bypass path which bypasses the power amplifier when excess gain and output power are not needed. When an RF-analog signal from the driver amplifier is switched to the amplifier path, the signal is band-pass filtered and amplified. Then the signal is split into an in-phase and a quadrature signal.  Either the in-phase or the quadrature signal is inverted and summed with the other of the in-phase or quadrature signal, and the summed signal is transmitted to an output port. When the RF-signal from the driver amplified is switched to the bypass path, the power amplifier is turned off and the bypass path directs the signal to the output of the power amplifier, which appears as a high impedance to the signal. The signal reflects off the power amplifier to the output port.
