Abstract: An aircraft vertical speed indicator is provided with the capability of displaying the relative position of other aircraft within a predetermined distance of the monitoring aircraft, the other aircraft being represented on the display by symbol characters (101, 109) and associated alpha/numeric information. When one of the other aircraft poses an immediate threat of collision, the character symbol representing the threatening aircraft on the display is changed and the color of the character symbol is color changed to facilitate identification of the threatening aircraft. The immediate threat of collision also causes two separate color regions (120, 121) to be displayed in conjunction with the vertical airspeed scale (103). The region (120) having a first color designates, on the vertical airspeed scale, the vertical airspeeds available to the monitoring aircraft that will result in collision of the two aircraft. The region (121) having the second color designates, on the vertical airspeed scale, vertical speeds that avoid the threatened collision.

Abstract: The toe piece binding (1) has a support bearing (13) which is mounted rotatably in lateral bearing blocks (7), fixed to the ski, and on which the ski boot (14) rests with positive fit in the touring position. To achieve this positive fit, the boot sole has a recess (22) which is matched to the support bearing (14) constructed as a straight shaft, and in which the support bearing fits. Serving for fastening the boot on this support bearing is a tightening lever (9) which is mounted so as to be swivellable by means of tensioning struts (8) and has at its one end a pressure piece (10) which presses onto the projecting edge of the boot sole (11) in its closed position in which the tightening lever is in an after-dead-centre position. For downhill skiing, the boot is placed directly on the ski and the tightening lever (9) is swivelled below the support bearing (13) and has at its end opposite the pressure piece (10) a holding-down device (12) for the sole which grips over the upper sole edge in the downhill skiing position. In order that the tightening lever mounted so as to be swivellable on the tensioning struts cannot escape upwards, it is held by the support bearing (13), below which it is swivelled for the downhill skiing position.

Abstract: An optical position determination system is described which determines the six degrees of freedom (i.e. position of orientation) of an object with respect to a two-dimensional position sensing detector (10). The system comprises at least three energy beams (32, 34, 36) physically connected to the object and directed to corresponding points of incidence on a surface of the position sensing detector (10). The energy beams are selectively energized to enable the position sensing detector to provide outputs indicative of the positions of the points of incidence. A microcomputer (54) is responsive to those outputs to calculate the position of their common point of intersection. A single position sensing detector is thereby able to provide complete, three-dimensional information on the position of the object.

Title: System for performing weighted summations
Inventor: ENGELER WILLIAM ERNEST
IPC: G06F15/18
Filed: 1991-07-31
Abstract: Plural-bit digital input signals to be subjected to weighted summation in a neural net layer are bit-sliced; and a number N of respective first through N th  weighted summations of the bits of the digital input signals in each bit slice are performed, resulting in a respective set of first through N th  partial weighted summation results. Weighted summations of the partial weighted summation results of similar ordinal number are then performed to generate first through N th  final weighted summation results. Each weighted summation of a bit slice of the digital input signals is performed using a capacitive network that generates partial weighted summation results in the analog regime. The weighted summation to generate a final weighted summation result can be done in the analog regime, which facilitates the analog final weighted summation result being non-linearly processed in an analog amplifier with sigmoidal response. This non-linear processing generates an analog axonal output response for a neural net layer, which analog axonal output response can then be digitized. Alternatively, the weighted summation to generate a final weighted summation result can be done in the digital regime and the digital final weighted summation result can then be non-linearly processed in digital circuitry with sigmoidal response. Where the neural net layer is to be trained using a back propagation training algorithm, the digital circuitry with sigmoidal response can be of a type where response slope is readily determined.
