Patent GB-2260966-A (GB)
Title: "infusion device"
Inventor: DANBY HAL
IPC: A61M5/172
Filed: 1991-11-04
Abstract: A microprocessor controlled volumetric infusion pump is set as to volume and rate of infusion by two digipots (shaft encoders) each having sixteen detented positioned in 360 degrees. The microprocessor is programmed such that the extent to which the parameter is changed for a given rotation of its setting digipot depends on the speed with which the digipot is rotated. For slow or normal rotation, unit change in parameter is produced for each detented position traversed. Faster rotation causes the setting to jump from one to the next of a series of preselected preferred settings, irrespective of the number of detented positions traversed. The direction of rotation determines whether the setting increases or decreases.

Title: Row interleaved frame buffer.
Inventor: ADAMS DALE R
IPC: G09G5/34
Filed: 1993-01-11
Abstract: The present invention utilizes a frame buffer operating in fast page access mode with improved performance for operations such as scrolling and moving which typically access different display memory rows. The present invention utilizes a row/bank interleaved scheme of multiple display memory banks in the frame buffer such that each display memory bank supports a different set of non-contiguous display rows thus increasing the odds of display memory access in-page hits and decreasing the odds of display memory access in-page misses. If the display comprises X display rows and the frame buffer comprises Y banks of display memory then for the Nth row, the Nth bank modulo Y of the Y banks is accessed. <IMAGE>

Title: Hue control of PAL video signals without chrominance demodulation
Inventor: CIARDI JOHN J
IPC: H04N9/64
Filed: 1994-02-17
Abstract: A hue control circuit for adjusting the color phase of a composite PAL television signal without demodulating the chrominance component of the composite PAL television signal uses a polyphase interpolator 14 to change the phase of the modulated chrominance component. A set of coefficients corresponding to a desired hue adjustment is applied to the polyphase interpolator. A hue coefficient address circuit 18 addresses a coefficient memory 16 containing a plurality of sets of coefficients, the sets being in complementary pairs. During each horizontal blanking line interval for a given desired hue adjustment the hue coefficient address circuit swaps the sets of coefficients between the complementary pair defining the desired hue adjustment in synchronization with the alternating sign of one of the color difference components of the modulated chrominance component on a line by line basis. The adjusted modulated chrominance component is combined 20 with the luminance component, suitably delayed 22, to produce an output composite PAL television signal with the desired hue adjustment. <IMAGE>

Title: Rotatable corner protector
Inventor: PERRY KENNETH JAMES
IPC: E04F19/02
Filed: 1994-07-08
Abstract: A corner protector particularly for doorways and corridor corners in hospitals comprises a freely rotatable aluminium tube (10) and a mounting element (12) to which it is pivotally mounted through pivots (22) on brackets (18). The brackets conform to the external shape of the mounting element and roller assembled together.

Title: ID contact and connector for telecommunications
Inventor: TAYLOR TREVOR PETER
IPC: H01R4/24
Filed: 1994-07-28
Abstract: An insulation displacement contact has two ID slots 110, 116 separated by a link 118 severable by wire cutters. Auxiliary ID slots 112, 114 are provided. The link allows a load to be mounted between an incoming and a subscriber line. A terminal block (100, figure 8) shields the slots but the link extends through a housing aperture for easy severance. An alternative contact has an ID slot 32 and a pair of auxiliary ID slots 46 joined by bridges 54. Plural alternative contacts are mounted in the single housing of a jack connector module 10 to dispense with a connecting PCB. The slots 32 are received in the cavities of a line IDC 22, the auxiliary slots 46 in an IDC 26 and the contact tails 56 protrude into a jack 18. The tails are separated by walls 70 which increase the electrical distance between the tails and so reduce the risk of damage caused by moisture or accumulated deposits in the jack. The module 10 can be mounted on the rear of a face plate and an adjacent screw terminal block (130, figure 10) used to link drop wires to the IDCs. A mastering component module (60, figures 6, 7b) may be inserted into the auxiliary IDC. <IMAGE>
