Title: Vacuum cleaner
Inventor: WOERWAG PETER
IPC: A47L5/00
Filed: 1993-02-26
Abstract: ABSTRACT       Disclosed is a vacuum cleaner of the type having a receiving drum which is closed by a cover containing the drive motor and the suction fan.  Vacuum cleaners of this type have a high centre of gravity and tend to tip over easily when the suction hose is moved, the hose being attached to a suction connection on the cover.  Movement of the vacuum cleaner also loads the bearings and carbon brushes of the motor.  A suction connection located in the cover is constructed as an angular connection, one section for the connection of the suction hose lying approximately radially with respect to the longitudinal central axis of the vacuum cleaner and another section leading approximately vertically into the receiving drum at a distance from the longitudinal central axis of the vacuum cleaner.  To reduce the aforementioned problems, the other section of the angular connection, according to the present invention, is held close to the central axis in a radially open compartment of the cover so that it is able to tilt vertically as well as horizontally.

Title: Tracking-servo-system controller in an optical-disk player
Inventor: NOMURA MASARU
IPC: G11B21/10
Filed: 1993-05-19
Abstract: ABSTRACT OF THE DISCLOSURE     A tracking-servo-system controller in an optical-disk player according to the present invention uses a high-pass filter   to   extract   from   a   readout   signal   an alternating-current component which is  not  affected by variations in the reflectance of a disk, and produces a control signal for initiating a pull-in operation of the tracking  servo  system based on the alternating-current component.  Firstly, a comparator detects a zero crossing of the alternating-current component.  Secondly, a pulse generator produces a pulse on the zero crossing.  Thirdly, a D flip-flop is activated by the pulse.  An output of the D flip-flop is sent as the servo control signal to the tracking servo system.  The tracking servo system starts the  pull-in  operation  on  the  zero  crossing  of  the alternating-current component.   It is  thus  possible to achieve a stable servo irrespective of variations in the reflectance of the disk.

Title: Process for the production of lenses with a variable refraction index
Inventor: HARRISON DAVID
IPC: H01Q15/08
Filed: 1992-05-25
Abstract: 2109936 9222846 PCTABScor01 This invention presents a process for the production of a lens with a given variable refraction index by fixing together several parts, at least some of them have a variable refraction index. The realization of the desired refraction index of the parts can be achieved by compressing dielectric material of a first shape into its final shape or by a doping or a mixing process respectively.  Outer parts, which extend to the outer surface of the lens to be produced, have a pyramid-like shape with a pointed or truncated apex respectively. In the first case the apexes of the outer parts meet in the symmetry point of said lens; in the latter case a center part is used which is located around said symmetry point.  It is also possible that some of the outer parts used have pointed apexes and the rest of them has got truncated apexes. In this case a center part used is easy to fix near the symmetry point of the lens. If dielectric material is taken, the lens to be produced can preferably be used as part of microwave antenna system.

Title: Method of determining range data in a time-of-flight ranging system
Inventor: KORBA LARRY W
IPC: G01S15/931
Filed: 1994-03-11
Abstract: A time-of-flight range sensing system for a vehicle such as a mobile robot comprised of a number of sensors that are situated at preset locations and aligned with particular orientations on the vehicle. Each sensor may consist of single or multiple transmitting transducers and single or multiple receiving transducers.  Each sensor provides a means for changing the effective sensing volume of the sensors or it has two or more separate processing channels for processing the time-of-flight information with several different effective sensing volumes using the sensor signal processor.  The sensor signal processor also provides a means for collecting information regarding the echo signal peak value and the noise present in the received signal before reception of the first echo.  A sensor array processor excites the transducers, measures the time-of-flight of arrival of the first echo above a predetermined threshold and combines the data from the multiple signal processing channels so as to increase the range data gathering speed and to improve the fidelity of the range data received.  The sensor array processor determines from the range data received and the signal and noise information the position and orientation of gross geometric features in the environment (flat surfaces, posts inside corners and outside corners) relative to the sensor array.  This information may be used by a navigation control processor to avoid collisions, recognize features in the environment, or map the environment.
