Title: Processo de medir representações da condutividade elétrica de uma solução aquosa que compensa polarização
Inventor: CHAN WAY YIN CEDRIC
IPC: G01N27/06
Filed: 1999-05-07
Abstract: "PROCESSO DE MEDIR REPRESENTAçõES DA CONDUTIVIDADE ELéTRICA DE UMA SOLUçãO AQUOSA QUE COMPENSA POLARIZAçãO" Um sistema de medição de condutividade provê um ou mais pulsos de CC  para primeiro e segundo eletrodos submersos em uma solução aquosa como, por exemplo, a água de lavagem de uma máquina de lavar pratos industrial. A tensão no primeiro eletrodo é medida em primeiro e segundo tempos predeterminados depois de iniciação de pulsos de CC. Regressão linear da primeira e segunda tensões medidas é usada para calcular a tensão no primeiro eletrodo no começo do pulso de CC, em tempo t = 0. A tensão resultante em tempo t = 0 é então usada para calcular a condutividade da solução, por esse meio compensando os efeitos de polarização. Ademais, a diferença entre as respectivas primeira e segunda tensões medidas é comparada a um valor limite predeterminado para determinar se os eletrodos estão tão contaminados que compensação polarização não é mais possível, assim sinalizando que os eletrodos deveriam ser limpos ou substituídos.

Abstract: Microcellular polyurethane elastomers having sharply reduced or virtually no urea linkages may be prepared without resort to organic physical blowing agents by frothing a frothable mixture containing isocyanate reactive polyols and chain extenders, and a frothable isocyanate component. The isocyanate component is derived by reacting a stoichiometric excess of a di- or polyisocyanate with a polyol component containing an ultra-low unsaturation polyol. The froth-produced elastomers surprisingly exhibit greatly improved tear strengths, compression set, and other physical properties as compared to all water-blown microcellular elastomers of the same density.

Filed: 2000-03-02
Abstract: A computer system for providing an on-line user conducting a search on a broad topic or category with a more sensible result set of documents derived from a set of easily definable specific categories. The system has a recursive hierarchical structure allowing the same scoring logic to be used at any level. A categorisation engine classifies the importance of specific categories for particular documents and these results are collated and indexed by a search engine. At run-time, a user's search on a broad category is translated into an equivalent search on at least one associated more specific category and typically a Boolean combination of a plurality of more specific categories. This allows the system to populate broad categories with related documents from more specific categories.

Title: Reducing background-noise from a siren
Inventor: TOWNSEND DAVID MARK
IPC: G10L21/0208
Filed: 2000-03-13
Abstract: Interference by siren background-noise with speech transmitted from radio equipment 3 of an emergency-service vehicle, is reduced by apparatus 1 that subtracts an estimate <EMI ID=2.1 HE=7 WI=5 LX=897 LY=972 TI=MF> <PC>of the correlated siren-noise component from the contaminated signal <I>y<SB>k</SB></I> supplied by the cab-microphone 2. The estimate <EMI ID=2.2 HE=7 WI=5 LX=1273 LY=1101 TI=MF> <PC>is computed by FIR (finite impulse response) filtering of a siren-reference signal <I>x<SB>k</SB></I> supplied by a unit 4 from one or more microphones located on or near the siren, or from the electric waveform driving the siren. The filter-coefficients <I>w<SB>k</SB></I> are adjusted according to an LMS (least mean square) adaptive algorithm that is applied to an error signal <I>e<SB>k</SB></I> of the correlated-noise component of the fed-back noise-reduced signal, so as to bring about iterative cancellation with close frequency-tracking, of the siren noise.

Title: Transmitter for mobile terminal with carrier leak suppressing circuit
Inventor: NAKAJIMA TOSHIKAZU
IPC: H04J13/00
Filed: 2000-07-28
Abstract: A power controlled transmitter suitable for a CDMA mobile terminal is of small size and low power consumption and suppresses the effect of carrier leak in the state where the transmitter output is controlled at a low level. A carrier control circuit 200 comprises a reference voltage generator 102, a comparator 103, and a controller 104. The comparator 103 determines whether the level of a control signal Vagc is higher or lower than a reference voltage Vs. Based on the determination result of the comparator, the controller 104 controls the gain of a local variable amplifier 111 such that the distortion characteristic of the transmitted output is optimal when the control signal is higher than the reference voltage, and the effect of carrier leak on the transmitted output is suppressed when the control signal is lower than the reference voltage. The reference voltage may itself be adjustable via the central processing unit (105, fig.6) and may be represented digitally (301).

Title: Locking mechanism suitable for use in office type chairs
Inventor: ELAM MICHAEL
IPC: A47C1/026
Filed: 2000-08-04
Abstract: A control handle 13 of an office type chair is pivotable about shaft 21, to which is attached cam 23. Cam 23 includes a notch 27 and a slot 31. Member 33 rides in slot 31. The control handle is normally biassed by a spring (not shown) to a first position where the chair mechanism controlled by the lever is locked. Rotation of the lever to a second unlocking position causes cam 23 to rotate and spring loaded detent 29 to engage with notch 27. The lever is thus held at its second position. Further rotation of the lever and thus cam 23, entrains member 33 at the end of slot 31 and subsequently causes it to displace detent 29 from notch 27. The lever can now spring back to the first locking position. A second embodiment of the invention is shown in Figure 8. Here the lever is held in the second position by pin 55 engaging with hook 75 of cam 51. Pin 55 is connected to pin 53. Rotation of the lever past the second position causes the cam to displace pin 55 and thus pin 53 is displaced from hook 75, allowing the lever to return to its first position.

Title: Detecting fatigue in machine operator or vehicle driver
Inventor: PEARCE PHILIP JOHN
IPC: G08B21/06
Filed: 2000-08-17
Abstract: A pattern of operator or driver control actions is measured at the start of a period of operation of the machine or vehicle, stored, and then compared with later determined or calculated patterns or profiles of control actions. When the differences exceed a predetermined amount, a warning signal is initiated and, if appropriate, the machine or vehicle is brought to rest. In a road vehicle, a pressure sensor 1 forms part of the steering wheel and a processor 5 analyses and records the pattern of variations in effort applied to the wheel by the driver over a period of time. An initially stored pattern is then compared with successive patterns during the period of driving. Other factors, such as steering wheel deflection, accelerator or brake pedal use, road speed, suspension movements, roll and vehicle position, may be taken into account by the processor.
