Title: System for overlaying information
Inventor: SCHNEIDER THOMAS
IPC: G08C15/00
Filed: 1997-05-20
Abstract: The invention is based on a system for overlaying information. The information is represented by a formed analog signal, this signal periodically having two predeterminable levels (high, low) and the information being represented by the period duration of the analog signal. The predeterminable levels (high, low) of the analog signal can be achieved by two different current or voltage values. The other information exists in the form of a formed digital signal which represents information in the form of a digital data word. The core of the invention resides in the fact that the digital signal is overlaid on the analog signal to form an overlay signal. In the vehicle mounted system shown, break wear, air gap and direction signals BBV, LS and DR are combined with speed signal DF.

Patent GB-2317064-A (GB)
Title: Delta-sigma modulator
Inventor: FUJIMORI ICHIRO
IPC: H03M3/02
Filed: 1996-06-06
Abstract: A delta-sigma modulator which converts analog signals into digital signals and maintains the linear gain relation between the analog and digital signals. The modulator is contrived by applying the over-sampling technique and the delta-sigma technique to a cascade-connected multi-order circuit. A local feedback loop is formed by connecting the output node to the input node of at least one of the succeeding-order integrators provided in the first and succeeding stages of a cascade-connected A/D converter. The local feedback loop monitors the output of the connected integrator and maintains the input levels at the second and succeeding stages by modulating the output of the integrator by local feedback. The succeeding stages are appropriately scaled, and hence the quantization noise produced at the first stage is perfectly eliminated. Noise leaking out from the first stage due to some direct causes does not interfere the digital signals generated by a noise eliminating circuit at all.

Title: Coupling for fluids with tap
Inventor: STEER PETER LESLIE
IPC: A61M39/10
Filed: 1998-02-13
Abstract: The coupling, e.g. for connecting a urine drainage tube to a urine collection bag (14), consists of a housing member (16) attached to the tube, a bagside member (18) attached to the bag, and a manually movable locking/tap member (22) which serves to lock the coupling members together and to provide an automatic tap (42) to close the fluid path in the housing member (16) when the coupling members are not locked together. The lock is external to both the housing member and the bagside member so that the state of engagement can be seen easily. The tap (42) and the lock (22) may be rotatable about an axis generally perpendicular to the fluid flow path through the coupling, the lock being in an "in-line" position when locked. Alternatively, the lock and tap are slidable perpendicular to the fluid flow direction, the lock having a fork end. A preferred hygiene feature is that surfaces of the housing and of the tap which are in direct contact with the fluid flow path when the coupling is assembled and the tap is open, are not exposed to external atmosphere when the coupling is separated with the tap closed.

Title: Etching contact windows
Inventor: WANG FANG
IPC: H01L21/768
Filed: 1998-05-27
Abstract: In a 3-step etching method for contact windows 43 in integrated circuit devices, the first step is an anisotropic etching, the second step is an isotropic etching and the third step is an anisotropic etching, where the ratio of the etching depth B formed by the third step to the total etching depth A+B formed by said three steps is less than 0.5. The resultant contact window has a better aluminum step coverage, making more reliable electrical connections and without increasing the cost. The method may be used to etch contact windows in a SRAM having an oxide layer 14 over a polysilicon gate layer 12. The three step method using NF 3  etching gas enables the formation of windows with a reduced depth ratio B/A+B.
Patent GB-2325892-A (GB)
Title: Preparing printing plates
Inventor: WATKISS PHILIP JOHN
IPC: G03F7/07
Filed: 1998-06-03
Abstract: A method of preparing a lithographic printing plate which involves providing a plate precursor comprising a grained and anodised aluminium substrate coated with a metallic silver layer, imagewise exposing the precursor to a high intensity laser beam, to the metallic silver layer in the exposed areas and treating the plate by chemical and mechanical means in order to remove stains on the plate surface. The method provides press ready plates free of background stain, which give a clean, even appearance in exposed areas and show high image resolution and excellent durability on press, whilst eliminating the requirement for the use of intermediate film and developer chemistry. The chemical treatment preferably involves an oxidant, such as a ceric salt or a mereapto compound, and an enzyme, surfactant, sequestering agent (e.g. EDTA), and a buffer may also be present. Scrubbing with a rotating brush or roller is the preferred mechanical treatment.

Title: Intracellular handover of mobile to simulcast carrier
Inventor: THOMAS HOWARD JOHN
IPC: H04W36/06
Filed: 1998-06-10
Abstract: A group of cells (2, fig. 1) e.g. picocells or microcells, within the coverage (11, fig. 1) of a common simulcast carrier or umbrella cell, each transmit an identical broadcast signal on the same simulcast carrier frequency f5. A mobile station (4, 4', fig. 1) in this communication network, is arranged to intermittently perform an intracellular handover to the common simulcast carrier, that is, to an uplink timeslot TS2 on the simulcast carrier frequency and while the mobile is using the common simulcast carrier, measurements of the radio environment are performed. For example, a mobile station in a call using a timeslot TS1 in a traffic frequency f2 different from the simulcast carrier frequency f5 receives a control signal (5, fig. 1) on the carrier f5, generated possibly in response to detection of a low signal level or quality, that instructs the mobile to handover to the simulcast carrier frequency TS2. The timeslot freed in the traffic channel TS1 is then available to the picocellular head (1, fig. 1) for interference measurements to assist in frequency allocation between the network cells. Alternatively all the picocellular heads in the simulcast cells may make uplink measurements on the mobile using the simulcast carrier f5, to determine the best picocell for handover. The mobile may also be arranged to be assigned temporarily to the simulcast carrier when it originates a call, allowing uplink measurements to be made to select the most appropriate cell. Arrangements avoids frequency ambiguities associated with downlink measurements made by mobile stations prior to handover in conventional simulcast systems.

Title: Apparatus and method for optimizing max-min fair rate control in Available Bit Rate (ABR) sessions
Inventor: KUMAR ANURAG
IPC: H04L12/70
Filed: 1999-03-24
Abstract: A method and/or apparatus are disclosed for determining an optimum Link Control Parameter (LCP) for insertion into the Explicit Rate (ER) field of a Resource Management (RM) cell. The LCP value is based upon per port Available Bit Rate (ABR) activity and provides fairness amongst ABR sessions. The LCP value is periodically determined for each output port and is based upon the number of ABR cells passing through a particular output port, available ABR capacity, the number of sessions passing through the port and a stochastic approximation gain. If the LCP value is lower than the value contained in the ER field of the RM cell travelling through the switch then the value in the ER field is replaced by the LCP value. When the sender receives an RM cell, the transmission rate is adjusted in accordance with the associated LCP value. The headers of all incoming cells are examined to determine whether they are ABR cells, the VPI/VCI values are used to determine the number of the corresponding output port and counters are provided for counting the number of ABR cells passing through each output port.

Title: Surface acoustic wave filter
Inventor: TANIGUCHI NORIO
IPC: H03H9/145
Filed: 1999-05-19
Abstract: A ladder-type filter is composed of'series' resonators S1, S2 and 'parallel' resonators P1, P2 and P3. The resonators are one-port surface acoustic wave resonators (see fig 5). In order to remove irregularities from the passband characteristic of the filter and improve its VSWR behaviour, the resonant frequency of one of the parallel resonators is set to be different from the resonant frequencies of the other parallel resonators. Preferably the different resonant frequency is slightly lower according to the following formula: f2 > f1 > 0.99f2 where f1 is the resonant frequency of the 'different' parallel resonator and f2 is the resonant frequency of the other parallel resonators. The resonant frequency of the resonator may be changed by adjusting the spacing of the finger elements of the interdigitated transducer.
