Title: Transaction system
Inventor: MCCRINDLE JOHN ALEXANDER
IPC: G07B15/06
Filed: 1986-03-26
Abstract: A transaction system enables a portable token having an on-board data processing capability to co-operate with a fixed terminal. The token is inductively coupled to the terminal, and receives data from the terminal via a frequency modulated carrier signal. Data is sent from the token to the terminal by amplitude modulation of the carrier signal from the terminal, i.e. by modulating the power drawn by the token from the terminal. The power needed to energise the on-board processing capability of the token is also obtained from the terminal via the inductive coupling and includes means for detecting a variation in the power demand which is indicative of the presence of an inductively coupled token. The token includes an arrangement for commencing processor operation in an orderly manner when it is brought into the proximity of a terminal, and for providing an orderly shut down when the token is withdrawn.

Title: Multiwell assay tray assembly.
Inventor: MERSON JAMES RICHARD
IPC: B01L3/00
Filed: 1990-04-25
Abstract: An assay tray assembly and an assay tray primarily for chromatographic analysis has a plastics moulded test tray 1 mounted on a plastics moulded collection tray 72. The test tray has a spaced array of chambers 3 disposed as per a microtiter plate. Each chamber has a bottom outlet port 5 formed by a flange 8 which retains within the chamber a chromatographic medium to which test liquid deposited in the chamber is to be subjected for the percolate or eluate liquid to emerge from the respective outlet ports. The collection tray 72 has a spaced array of wells 16 disposed as per a microtiter plate to correspond with the chambers 3 and the tray 1 is mounted on the tray 72 for each chamber to communicate with a corresponding well 16. Each chamber 3 has a tubular spigot part 12 which extends into the respective well 16 to alleviate cross contamination of the liquid derived from the outlet ports 5. The depth of entry of the tubular spigots 12 into their respective wells 16 is restricted by abutment between the bottom of the test tray with the top of the collection tray. The volume of each well 16 beneath the tubular spigot it receives is adequate to accommodate all of the eluate or percolate derived from the chamber 3 with which it communicates to alleviate liquid on the spigot parts from dripping into wells with which those tubular spigots are not associated (and thereby cause cross contamination) when the trays are separated for analysis of the percolate or eluate. <IMAGE>

Title: A method of determining the initial values of the coefficients of a transversal equalizer
Inventor: OESTMAN KJELL
IPC: H04L25/03
Filed: 1990-05-25
Abstract: The invention relates to a method of determining the coefficients of a transversal equalizer used in the receiver of a data communication system by sending a known periodic data sequence (training sequence) over the communication channel, by calculating the discrete Fourier transform C(k) of the equalizer by means of the received data sequence either directly or through the discrete Fourier transform U(k) of the channel, and by calculating the coefficients of the equalizer by an inverse discrete Fourier transform from said discrete Fourier transform C(k) of the equalizer. In order that the coefficients could be calculated by means of a shorter training sequence, the method is characterized in that the number of the spectral components of the discrete Fourier transform of the equalizer or the channel is increased by interpolating intermediate components between the original spectral components before said calculation of the inverse discrete Fourier transform. <IMAGE>

Title: Data bypass structure in a register file on a microprocessor
Inventor: ARNOLD JAMES M
IPC: G06F9/38
Filed: 1991-01-17
Abstract: A register file on a pipelined microprocessor chip has a bypass structure (16, 24) that drives the correct source data from an immediately previous write result to guarantee the most recent data is utilized when executing an instruction stream in the pipeline. Load data or execution result data (52) are returned to the RAM array register file (18) in the second phase of a cycle but is actually written into the RAM Array into the cells in the first phase of the succeeding clock cycle. To avoid an instruction from being delayed one cycle waiting for the data to be written into the RAM and then read out again, bypass logic routes the returning Load or execution result data directly onto the column lines of the read ports of the source busses during the second phase of the cycle that the data is returned. <IMAGE>
Patent GB-2241162-A (GB)
Title: Liquid applicator
Inventor: KIMURA MASARU
IPC: A46B11/00
Filed: 1991-02-11
Abstract: An inner shaft (1) contains liquid which is discharged to a brush (3) via a valve (4). In order to prevent accidents, such as dropping the applicator, from causing unwanted opening of the valve (4) as a result of the inertia of the inner shaft (1), a non-circular head portion (24) is provided on the front of the inner shaft (1). The head portion (24) has only a single rotational position at which it can advance through a hole (27) in a wall (28) of an outer shaft (2), see Fig. 5. At other rotational positions, the inner shaft (1) is prevented from moving forwards to cause unwanted opening of the valve (4). <IMAGE>

Patent GB-2244626-A (GB)
Title: Image correction in telecines
Inventor: GRIFFITHS MICHAEL JOHN
IPC: H04N5/257
Filed: 1991-03-28
Abstract: Damage to film can be caused by repetitive winding backwards and forwards during the setting of correction parameters to be applied to a video signal by a telecine. This damage may be avoided by deriving parameters which compensate, e.g. for contract ratio reduction, colour rendition and resolution losses may be derived from a scene of film stored in a multiple frame store 18. A scene of film is scanned and loaded into the frame store and can be replayed repeatedly until all correction signals have been derived. The correction signals are then loaded into the telecine pre-programmer and the film is transferred to video with the telecine in run mode. Grading may also be performed on the contents of the multiple frame store. <IMAGE>
