Abstract: The measurement procedure assesses the interference of an audio signal or test signal, respectively, (1a,b) by comparing it with a reference signal (1c,d) that is not subject to interferences.  After pre-filtering (2) with the transmission functions of the outer and middle ear, the input signals are converted into a time-tonality representation . The squares of sums (5) of the filter output signals are calculated (rectification) and folding of the filter outputs is carried out with a smearing function (4). The folding can be done either before or after rectification. Level differences between test signals and reference signals, as well as linear distortions of the reference signals are compensated at (7) and evaluated separately. Then, at (8), a frequency-dependent offset is added in order to model the inherent noise of the auditory process., and the output signals are time smeared at (9). In order to save computer time, some of this time smearing can take place immediately after rectification (4). After time smearing (8) (low-pass filtering) it is then permissible to underscan the signals. A series of output values can be calculated at (10) by comparison of the resulting aurally corrected time-frequency patterns of test and reference signals (1a,b and 1c,d); these output values provide a assessment of the perceivable interference.

Abstract: A combination mop bucket and wringer unit uses a thin walled plastic mop bucket with a cap-like wringer body which fits securely over the top of the bucket to form a unitary structure. The wringer body adds rigidity to the thin walled mop bucket so that it is able to resist the downward force of the wringer handle lever without buckling. The bucket may be lifted or otherwise moved using only the handle lever. The combination or unitary structure lifting a wringer, a bucket, a mop handle and a mop. Use in small cleaning areas where the combination bucket and wringer is carried from area to area is ideal for this device.

Abstract: A marker suitable for use in a golf fairway having a base portion suitable for installation in a ground hole, and a hollow upper body portion fixed to the upper end of the base portion which includes a dome formed of resilient material. The dome has a normal, unstressed raised condition in which it protrudes above ground level, to be readily visible to golfers, and has a depressed condition in which it is close to ground level and in which the material is stressed such that it tends to move to the normal, raised condition. A generally closed chamber beneath the dome has one-way valve means which allows air to be rapidly expelled from the chamber when the dome is depressed but restricts air flow into the chamber to delay recovery from the depressed condition.

Abstract: A communications interface system receives an initial address message for a call into a circuit process and transfers the initial address message to a call process.  The call process processes the initial address message to generate and transfer set-up information to a bearer system. The bearer system receives user communications for the call and routes the user communications in response to the set-up information. The circuit process receives a release message for a call and transfers the release message to the call process. The call process processes the release message to generate and transfer tear-down information and a disconnect message. The circuit process generates and transfers a release complete message in response to the disconnect message. The bearer system terminates the routing of the user communications in response to the tear-down information.

Abstract: A food storage system mounted in a fresh food compartment of a refrigerator includes an enclosure defined by inner and outer housings, as well as a food receptacle slidably positioned in the inner housing.      The inner and outer housings are spaced so as to define a zone therebetween within which air is forced to flow in order to cool the contents of the receptacle. A tunnel insert is positioned in a mullion zone defined between fresh food and freezer liners of the refrigerator, with the tunnel insert being formed with a through hole for directing the flow of cooling air into the food storage system, a channel for directing an exhaust flow of cooling air from the food storage system out of the fresh food compartment within them mullion zone and an enlarged opening defining a return air passage for the overall fresh food compartment. The tunnel insert, within the mullion zone, channels the exhaust air from the food storage system to the return air passage. The channel is preferably defined by four walls, three of which are created by a groove formed in the tunnel insert and the fourth wall being defined by a portion of the fresh food compartment liner which seats against the tunnel insert. An air inlet cover is provided to extend over supply air openings formed in a freezer liner of the refrigerator, with the inlet cover including forwardly angled louvers to assist in directing a flow of cooling air to the food storage system.

Abstract: Display techniques to deal with viewpoint changes such as, so-called "pyramidic panel structures" are employed to adjust the image's vanishing point(s) in accordance with the movement of the user, such structures have the disadvantage that they work primarily for so-called "corridor-like" two-dimensional images. I have recognized that, in accordance with the principles of the invention, viewpoint changes may be also dealt with by partitioning the two-dimensional image into polygon partitions, each corresponding to a surface being depicted in the image, and then coupling the vertices of the polygon partitions with the movement of the user so as to limit distortions. In this latter approach, two-dimensional images are not treated as a perspective, corridor-like image, thereby allowing a wider variety of two-dimensional images to be used with the present invention.

Title: Method for manufacturing a multi-layered moulded synthetic part and thus obtained part
Inventor: DE WINTER HUGO
IPC: B29K105/04

Granted: 2006-09-19
Abstract: The invention relates to a method for manufacturing a multi-layered moulded synthetic part comprising a preformed elastomeric moulded skin (5), a moulded carrier (8) of a thermoplastic material and optionally an intermediate foam layer (6). In this method, the elastomeric skin (5) is moulded in a first step and the thermoplastic material for the carrier (8) is subsequently moulded in molten state to the back of said moulded skin (5). According to the invention, the moulded skin is made of a thermosetting synthetic material.  Compared to a thermoplastic skin, such a thermosetting skin is less subjected to visible defects, in particular in case it has been provided with a superficial texture such as a leather grain, when the thermoplastic carrier is moulded thereto. Moulding of the thermoplastic carrier can be done by an injection moulding, an injection pressure moulding or a low pressure moulding technique.

Abstract: A fused tension-based fiber grating pressure sensor (8) includes an optical fiber (10) having a Bragg grating (12) impressed therein.  The fiber (10) is fused to tubes (20) on opposite sides of the grating (12) and an outer tube (30) is fused to the tubes (20) to form a chamber (34). The tubes (20, 30) and fiber (10) may be made of glass. Light (14) is incident on the grating (12) and light (16) is reflected from the grating (12) at a reflection wavelength (.lambda.1). The grating (12) is placed in tension pre-strain and as the pressure (P) increases, the tension on the grating (12) is reduced and the reflection wavelength shifts accordingly. A temperature grating (50) may be used to measure temperature and allow for a temperature-corrected pressure measurement. The shape of the outer tube (20) may have geometries other than a straight cylinder. Also, the axial ends of tubes (20) where the fiber (10) exits the tubes (20) may have an inner region (22) and/or a protruding tapered (or fluted) axial section (27), to provide strain relief or improved pull strength of the fiber (10). More than one grating or pair of gratings may be used and more than one fiber (10) may be used. The fiber (10) may be doped at least between a pair of gratings (150, 152) to form a tunable fiber laser or the grating (12) or gratings (150, 152) may be constructed as a tunable DFB fiber laser.
