Title: Wiener-like filter for cellular radio
Inventor: HULBERT ANTHONY PETER
IPC: H03H17/02
Filed: 1993-04-15
Abstract: A Wiener filter can be applied to give optimum estimates of the complex fading signal characteristic from noisy measurements. The performance of a Wiener filter is only marginally degraded if groups of adjacent coefficients are set to the same value, provided that the Wiener filter produces frequent outputs. Apparatus is provided for implementation of a filter in which sets of adjacent taps have the same value. This results in reduced hardware complexity. <IMAGE>

Title: Pump operation detector system
Inventor: DAWSON PETER P
IPC: G08B21/20
Filed: 1993-04-28
Abstract: The system comprises a pressure sensor (26) on the output side of the pump (12) which generates a signal which is fed to a control unit (20), the control unit being arranged to generate an alarm signal if it does not receive a pressure signal a predetermined time after receiving a product demand signal. A demand signal from an industrial washing machine will cause the relevant pump to pump detergent or other chemical product. This signal is also fed to the control unit of the system of the invention. A predetermined time after receiving the demand signal the control unit "looks" for a pressure signal and, if this is present, no alarm is generated. If, on the other hand, the pressure signal is absent this indicates that the pump is not working or not working properly and an alarm signal is generated. <IMAGE>

Title: Voice coding communication system
Inventor: SASAKI SEISHI
IPC: G10L19/12
Filed: 1994-12-08
Abstract: A low-delay code excited linear prediction (LD-CELP) voice coding system applied to a scheme, in which the transmitting side interrupts transmission during the voice-nonactive period and the receiving side generates and outputs a comfort noise during the voice-nonactive period. At the transmitting side, when voice non-activity is detected by the voice activity detector (2), the CN flag indicating the interruption of transmission is sent from the CN flag generator (3) and shortly thereafter a background noise from the LD-CELP encoder (1) is sent, followed by the interruption of transmission. At the receiving side, when the background noise following the CN flag is decoded by the LD-CELP decoder (9), the internal gain and synthesis filter coefficients are held, which is subsequently used to decode the input from the pseudo-noise generator, to produce comfort noise. The decoder may include an excitation codebook followed by a controllable gain scaling unit and a controllable filter. <IMAGE>

Title: Broad spectrum ultraviolet catadioptric imaging system
Inventor: SHAFER DAVID R
IPC: G03F1/84
Filed: 1997-01-07
Abstract: An ultraviolet catadioptric imaging system, with broad spectrum correction of primary and residual, longitudinal and lateral, chromatic aberrations for wavelengths extending into deep UV has a focusing lens group 11, a field lens group 15 and a catadioptric lens group 17. The focusing lens group has several lens elements 21-27 that provide high levels of correction of both image aberrations and chromatic variation of aberrations. The field lens group 15 comprises lens elements 51,53,55 formed from at least two different refractive materials, such as silica and fluoride glass. The field lens group 15 is located near the intermediate image 13 provided by the focusing lens group 11 and corrects the residual chromatic aberrations. The catadioptric group 17 has a first optical element having a concave reflective surface 41 providing most of the focusing power of the system and a thick lens 39 providing primary colour correction in combination with the focusing lens group. A second optical element of the catadioptric group 17 consists of a silica lens 43 with a reflective surface coating 45 on its back surface. The system has a high numerical aperture and a large flat field. Also provided is a method of inspecting objects for defects by illuminating the object with UV radiation, forming fluorescent UV images with a single broadband collector of UV images corresponding to different wavelength bands and converting the images to visible light for visual inspection. In a further arrangement an object is illuminated with ultraviolet radiation at multiple wavelengths, for each wavelength a corresponding ultraviolet image slice of the object is formed at different focal planes, and a composite image is formed by computer integration of the image slices, this composite image having greater depth of focus than any of its constituent image slices.

Filed: 1997-04-02
Abstract: A method of manufacturing a toy racket includes the steps of forming a rigid racket frame (20) having a looped head portion (21) and a handle portion (22) connected to the looped head portion (21), placing the racket frame in a mold (30), and injecting a resilient plastic material into the mold to form a resilient netting (23) confined within the looped head portion. The looped head portion has inner and outer sides and is formed with a plurality of connecting holes (211) that extend from the inner side to the outer side. The resilient netting has a plurality of insert portions (230) that extend into the connecting holes, and outer and inner connecting strips (231) that are disposed respectively on the outer and inner sides of the looped head portion and that interconnect respectively outer and inner ends of the insert portions. The connecting strips connect integrally the resilient netting to the looped head portion. The resilient properties of the netting enhance the impact-cushioning ability of the toy racket. Moreover, the toy racket can have a more realistic appearance since the netting and the looped head portion can be formed from different plastic materials.

Title: Coin validation method
Inventor: MULDER ARJEN JOHAN
IPC: G07D5/00
Filed: 1997-07-02
Abstract: A method of setting the coin checking criteria in a coin operated machine wherein a coin is determined to be acceptable if a measurement derived therefrom falls within a prescribed acceptability range, comprises setting a narrow acceptability range for "good" coins and outside that a wider acceptability range for "still good" coins, determining a desired frequency of coins whose derived measurements fall within the two ranges, counting the number of coins whose measurements fall within the two ranges, and, if the frequency of measurements within the "still good" range exceeds the desired frequency, reducing the width of said range. The width of the range may be restored, possibly in a stepwise manner, when certain pre-set conditions, eg passage of a predetermined time, are met.
