Inventor: HAGER JAMES R
IPC: G01S13/935
Filed: 2001-02-01
Abstract: A radar altimeter for determining altitude of an air vehicle comprises a transmitter for transmitting radar signals toward the ground. A first and a second antenna receive reflected radar signals from the ground. A signal processor is coupled to the first and the second antennas. The signal processor includes filter means for rejecting signals other than signals reflected from a selected ground swath. The signal processor determines the above ground level altitude of the air vehicle based on the radar signals output from the filter means. A phase ambiguity resolution means resolves phase ambiguities that arise due to multiple wavelength separation of the first and the second antenna. The signal processor also determines the horizontal position of the highest point in the selected ground swath. In a preferred embodiment, the phase ambiguity resolution means comprises a third antenna spaced closely to the first antenna such that there are no phase ambiguities between the reflected radar signals received by the third antenna and the first antenna.

Inventor: MENZIES BRAD C
IPC: B60T7/06
Filed: 2002-10-08
Abstract: A brake cover (18) and shaft (24) rotate with a pedal lever (20) relative to a central section (14) of the housing (12) rotate a pedal gear (76). The pedal gear (76) rotates a sensor gear (74) to rotate a sensor arm (46) about a sensor axis (48). The sensor arm (46) supports sensor members (58) that move along sensor bands (50) to generate an electrical signal. As the brake cover (18) rotates with the pedal lever (20) it uncoils coil springs (84) to cause brake shoes (80) to pivot radially outward about respective posts (82) frictionally engage the interior surface (78) of the central section (14) to thereby provide a resistance or hysteresis to movement of the pedal lever (20). One feature resides in at least two elements (74, 76) to interconnect the sensor arm (46) and the pedal arm (20) to reduce space while maintaining the requisite movement of the sensor members (58) over the sensor bands (50) and the other feature resides in spacing the braking mechanism axially from the sensor arm (46) in radially overlapping relationship to one another along the pedal axis (A).

Title: Video error resilience
Inventor: HANNUKSELA MISKA
IPC: H04N19/89
Filed: 2001-06-28
Abstract: The invention provides a method that reduces degradation in the perceived quality of images in a video sequence due to data loss. This effect is achieved by effectively delaying the insertion of an INTRA coded frame (50) after a periodic INTRA frame refresh, INTRA update request, or scene cut.  Frames associated with INTRA frame requests are not themselves coded in INTRA  format, but instead a frame (50) occurring later in the video sequence is chosen for coding in INTRA format. Preferably, the actual INTRA frame is selected such that it lies approximately mid-way between periodic INTRA  requests. Frames (P2, P3) occurring prior to the actual INTRA coded frame (50) are encoded using temporal prediction, in reverse order, starting from the actual INTRA frame, while those frames (P4, P5) occurring after the INTRA  coded frame (50) are encoded using temporal prediction in the forward direction.
