Inventor: FLECKENSTEIN THEO
IPC: C11D3/00
Filed: 1995-03-21
Abstract: Le produit nettoyant pour tapis se présente sous forme de préparation dispersible. Outre un agent pulvérulent adsorbant et un nettoyant aqueux adsorbé sur cet agent, la préparation contient aussi des particules de matière poreuse capables de rouler. Ces particules sont formées de préférence à partir de matière déformable, notamment des matières spongieuses absorbantes, et les plus grandes d'entre elles ont des dimensions entre 1 et 50 mm. En mélangeant ces particules, on réduit la tension mécanique exercée sur les fibres du tapis lors du brossage du produit nettoyant. L'élimination des peluches et des fibres détachées sur le tapis s'en trouve aussi facilitée.

Title: Method and device for processing a video image
Inventor: DETER CHRISTHARD
IPC: H04N7/01
Filed: 1996-04-26
Abstract: The invention concerns a method of processing a video image with image points in m1 lines, the points in the l1-th line having an intensity I1(t, l1) which depends on a parameter t, in particular time, in order to generate a second video image with m2 lines. The invention calls for the intensity I2(t, l2) of each image point in the l2-th line of the second video image to be interpolated from the intensities of the image points of the first video image I1(t, l1), the intensity I2 being obtained from the equation: I2(t,l2)=Max¢J(t,l2)+.DELTA.;0! in which J represents values, discretized with respect to the lines, of changes in signal defined by the scan theorem and which includes an offset .DELTA. for partial compensation of negative intensities of the discretized changes J in the signal, so that the interpolation is carried out with respect to the lines with A as a freely determined positive-value amplitude in accordance with the equation (1). The invention also concerns a device including circuit elements suitable for the generation of the second video image by the method proposed.

Title: Remote printing system
Inventor: SPERRING FOY C
IPC: G06Q30/00
Filed: 1996-12-30
Abstract: A Desktop Printing System (DPS) operable on a data processor enables the printing of a document created by an application program to be printed at a remotely located printing facility (RPF).   The DPS obtains formatting information from the document, and obtains user desired printing and binding preferences, which include paper type, binder type and color, and dividers for separating sections of the document.  Cost and tax tables stored on the data processor are utilized to generate cost and tax information for review by the user. The DPS provides several options for transmission of the document and user printing and binding preferences to the RPF.  The RPF includes an automated facility for accepting print orders from a plurality of DPSs.  Each print order is accepted, validated and stored, and credit information for payment of the print order is obtained.  Files required for printers to print a print order are generated and are queued for printing at a selected production plant.  Upon printing, each print order is finished and shipped to the user.

Patent CA-2200731-A1 (CA)
Title: Method and apparatus for regenerating a dense motion vector field
Inventor: OZCELIK TANNER
IPC: H04N7/26
Filed: 1996-05-24
Abstract: The present invention provides a method (300) and apparatus (100) for regenerating a dense motion vector field, which describes the motion between two temporally adjacent frames of a video sequence, utilizing a previous dense motion vector field. In this method, a spatial DVF and a temporal DVF are determined (302 and 304) and summed to provide a DVF prediction (306). This method and apparatus enables a dense motion vector field to be used in the encoding and decoding process of a video sequence. This is very important since a dense motion vector field provides a much higher quality prediction of the current frame as compared to the standard block matching motion estimation techniques. The problem to date with utilizing a dense motion vector field is that the information contained in a dense motion field is too large to transmit. The present invention eliminates the need to transmit any motion information.

Patent CA-2203156-A1 (CA)
Title: Hybrid filter bank analog/digital converter
Inventor: BROADSTONE STEVEN R
IPC: G10L25/18
Filed: 1995-10-19
Abstract: A hybrid filter bank analog-to-digital converter includes continuous-time analysis filters and discrete-time synthesis filters. The continuous-time analysis filters partition a continuous-time wibedand input signal into continuous-time subband signals. An analog-to-digital converter bank quantizes the subband signals at a low data rate. A bank of upsamplers increases the data rate of the quantized subband signals. A bank of discrete-time synthesis filters processes the upsampled subband signals, generating signals which are the discrete-time approximation of the continuous-time subband signals. The subband signals may be recombined into a discrete-time wideband signal which is the discrete-time approximation of the continuous-time wideband input signal. The linearity errors, analog-to-digital converter mismatches and quantization noise are not compounded between the frequency bands, thereby increasing resolution. The system may also include compensators for compensating for non-linear behavior in the analog-to-digital converters and may include application-specific processors for further processing of the compensated subband signals. An alternative embodiment employs discrete-time analysis filters and continuous-time synthesis filters for digital-to-analog conversion.

Patent CA-2205985-A1 (CA)
Title: Ventilation of medical gases
Inventor: KORCZYNSKI RITA
IPC: A61M16/00
Filed: 1995-09-01
Abstract: A downdraft system is used for withdrawing and collecting medical gases, fumes, mists and particulates from the vicinity of a patient's face. Two intakes (16) are located on respective sides of the patient's face, at the cheeks. The intakes extend from temple to chin. They are connected through a ducting system (28-46) to a source of vacuum (48) for collecting the medical gases. The ducting system is configured to allow the adjustment of the intake positions. The intakes create a flow of air across the patient's face from above the nose to below the mouth so that gases leaking during administration of gases or exhaled by the patient, and fumes, mists or low velocity particulates generated, for example, in orthodontic procedures, are captured in the flow across the patient's face into the intakes. This leaves the patient's mouth and nose fully exposed and unobstructed by the gas evacuation apparatus so that the administration of gases, dental treatments and any other procedures requiring access to the mouth and nose area may be carried out.

The inflation region includes a plurality of balloon lobes at the distal end of the catheter. The plurality of balloon lobes,when inflated, can center the radiation source within a curved section of the body lumen.
