摘要： A method is provided of determining the pixel drive signals to be applied to the pixels of an array of light emitting display elements arranged in rows and columns, with a plurality of the pixels in a row being supplied with current simultaneously along a respective row conductor. Target pixel drive currents are determined from a model of the pixel current-brightness characteristics. These are modified to take account of the voltage on the respective row conductor at each pixel resulting from the currents drawn from the row conductor by the plurality of pixels and the dependency of the pixel brightness characteristics on the voltage on the row conductor at the pixel. This addresses the problem of horizontal cross-talk that occurs in active matrix 1.RD displays due to the finite output impedance of the current providing TFT's as well as the finite resistance of metals used to form power supply lines.

摘要： A balanced gyrator comprises interconnected pairs of single-ended inverting class AB transconductors (TC1 to TC4) fabricated from MOSFETs together with common mode feedback circuits (26) connected between balanced inputs (18, 19) and outputs (22, 23). Peaking of the frequency response resulting from distortion due to the creation of a high frequency parasitic feedthrough path in the transconductors is overcome by the provision in each of the transconductors (TC1 to TC4) of a non-reciprocal feedback capacitance (Cf) which renders the feedthrough capacitance reciprocal thereby neutralising the feedthrough capacitance of the gyrator. The devices include a filter (FIG. 8, not shown) and a transceiver (FIG. 10, not shown).

摘要： An current mode analogue-to-digital converter uses a conversion stage which operates using a two-phase clock and which requires the input signal to be present during only one of the phases. A sample-and-hold circuit (120, 130, 135) samples the input signal during the first clock phase and during the second clock phase a quantised bit value is generated from a mirror of the held input current by a kickback-free comparator circuit (140). Also during the second clock phase a residue is generated using the quantised value and a non-mirrored version of the held input current. Optionally, two comparator circuits (140, 140″) may be used to provide two-level quantisation, enabling errors introduced by the current mirror to be corrected by a Redundant Signed Digit algorithm. Two pipelines of conversion stages (Si′ Si″ can be multiplexed to double the conversion rate.

摘要： A baggage chute for transferring baggage from an elevated level of an aircraft passenger boarding bridge to ground level. The chute includes at least one slide member which is shaped to form a truncated cylinder of arcuate cross-section and which has annularly extending ribs. A plurality of mounting members are used to fasten the slide member to the boarding bridge and to support the slide member. A baggage receiving area is attached near an end of the slide near ground level for receiving and retaining baggage. The receiving area includes a flexible member extending substantially across the receiving area for stopping the sliding of the baggage and which absorbs the impact of the baggage.

摘要： A method of treating a water-swellable clay after the clay has been mined and dried to improve its properties when in contact with salt-contaminated water. After the common initial drying of the clay to a moisture content of 12% by weight or less, the clay is rewetted to a moisture content of more than 12% by weight, preferably at least about 15% or more, based on the dry weight of the clay, then redried to a moisture content of 12% by weight or less, based on the dry weight of the clay. This rewetting and redrying processing of a dried clay unexpectedly improves the salt water absorbency, and viscosity properties when the clay is in contact with salt-contaminated water; unexpectedly increases the rheology properties of the clays for oil well drilling fluids and lost circulation fields when salt-contaminated water is encountered during drilling, as a suspending agent in the cosmetics and pharmaceutical industries when the composition contains a dissolved salt; and provides unexpectedly increased salt water-absorption in forming water-swellable clay-based water barriers.

摘要： A method of treating a water-swellable clay, initially having a Fe.sup.+3 /Fe.sup.+2 ratio of at least 1.0, preferably at least 3.0, and most preferably in the range of about 5.0 to about 15.0, after the clay has been mined and dried. After the common initial drying of the clay to a moisture content of 12% or less, the clay is re-wetted to a moisture content of more than 12% by weight, preferably at least about 15% or more, based on the dry weight of the clay, then re-dried to a moisture content of 12% by weight or less, based on the dry weight of the clay. This re-wetting and re-drying processing of a dried clay unexpectedly improves the water absorbency, and viscosity properties; increases the effectiveness of the clays as binders in sand molds and iron ore pelletizing; unexpectedly increases the rheology properties of the clays for oilwell drilling fluids, and lost circulation fluids, and as a suspending agent in the cosmetics and pharmaceutical industries; improves the binding characteristics of the clays to act as a binder for iron ores, such as taconite, and sand molding (foundry industry); and provides unexpectedly increased water absorption in forming water-swellable clay-based water barriers.
