Title: Method of operating a cableway system, and cableway system
Inventor: HINTEREGGER CHRISTOPH
IPC: B61L3/00
Filed: 2007-02-07
Abstract: A cableway system has a valley station and a mountain station. A supporting and conveying cable displace transport devices between the stations, and/or the system has at least one supporting cable, on which the transport devices are displaced with a conveying cable. The inclined positions of transport devices in relation to the vertical operating position are sensed by a respective sensor on the transport devices. When a first limit value for the inclined position of one of the transport devices is exceeded, a transmitter transmits a first control signal from the transport device to a receiver in one or both stations. The first control signal reduces the speed of the conveying cable. When a predetermined second limit value for the inclined position of a transport device is exceeded, a second control signal is transmitted to the receiver. The second control signal switches off the drive for the conveying cable.

Title: Electrostatic loudspeaker capable of dispersing sound both horizontally and vertically
Inventor: HARMAN MURRAY R
IPC: H04R19/02
Filed: 2007-04-12
Abstract: An acoustic transducer, specifically an electrostatic loudspeaker (ESL) providing curvature in two directions for improved dispersion of sound waves. The compound curvature also provides a virtual focus of the propagated sound waves for accurate reproduction of musical program material recorded with standard single-point microphones. The highly directional nature of high frequency sound waves requires that a flat or cylindrical electrostatic transducer must be physically tall to allow a listener to either recline or stand. The two-axis curved structure enables a compact form of ESL to be realized, including bookshelf type loudspeakers whereas all known commercial units are comparable in height to that of a human listener. The individual curved ESL panels can also be readily combined to create larger transducer assemblies including omni-directional units. A preferred stator panel hole-geometry is included for improved high voltage operation of coated perforated metal stator panels, and methods of forming the metal panel are described. The artistic nature of the two-dimensionally curved electrostatic transducer also lends itself to other non-traditional forms such as integration into lighting fixtures and other such architectural uses.

(1, 2). During measurement, a detector (7) is moved along such a curve of a circle that can be assumed to intersect the curve of the circle described by the edge of the object. The angular position of the detector (7) is measured using the curve of the circle over which it travels and the intersection points (xl, zl; x2, z2) of the curve travelled by the detector (7) and the edge of the object are detected. The location of the centre point (x0, z0) of the object is calculated on the basis of a) the radius of the circle travelled by the detector and the location (xm, zm) of the centre point of the circle, b) the location (xt, zt) of the tool point, c) the assumed radius of the object, and d) the locations (xl, zl; x2 z2) of the detected intersection points. Finally, the position of the centre point (x0, z0) of the object in the set of co-ordinates of the grab is calculated.

Title: Method for producing a medical implant made of a beta-titanium molybdenum alloy, and a corresponding implant
Inventor: BALIKTAY SEVKI
IPC: A61F2/36
Filed: 2006-02-27
Abstract: The invention relates to a method for producing a medical implant from a titanium alloy by precision casting the titanium alloy in a mold corresponding to the implant to be produced. The invention uses a ~-titanium alloy, hot-isostatic pressing, solution annealing and subsequent quenching. The invention also relates to a corresponding medical implant that is made from a titanium alloy in the precision casting method. The titanium alloy is a ~-titanium alloy and has a mean grain-size of at least 0.3 mm. The invention enables an efficient production of objects from ~-titanium alloys in the precision casting process. The invention thus creates the possibility of combining the advantageous properties of ~-titanium alloys, particularly their excellent mechanical properties, with the advantages of a production of objects in the precision casting process. Even implants having complex shapes, such as femoral parts (1) of hip joint prostheses, which could not or could not be sensibly produced by conventional forging methods, can now be produced from a ~-titanium alloy thanks to the invention.

IPC: G01S3/50
Filed: 2007-08-30
Abstract: A circuit and associated method for determining the heading of a vehicle or device with a satellite ranging system receiver is provided. The circuit requires only a single front end RF stage. A single RF stage can be used because the incoming signal received at the first antenna is delayed with respect to the signal received at the second antenna and the two signals are merged together, to form a combined signal.  The combined signal can be down converted and sampled in a single stage. The samples are then separately correlated to detect the data associated with the portion of the signal attributed to each antenna. The differences between the measured data are then used to calculate the relative orientation (heading and pitch) of the device upon which the two antennas are disposed.
