Title: Disk drive controller.
Inventor: SANDER WENDELL
IPC: G06F3/06
Filed: 1991-05-20
Abstract: A disc drive controller has read post compensation which corrects for peak shift effects on discs with insufficient precompensation. The data is recorded in Manchester (MFM) format and read into circuitry including SCT counter (451) which loads parameters representing a cell with a short-cell (2 unit) following it and LCT counter (453) which loads parameters representing a cell with a long cell (3 or 4 unit) following it. Bound detector 455 counts the number of pulses between transitions and shift registers (457, 459) store the number of pulses generated by the respective counters to enable the bound detector to generate peak shift compensated pulses. The controller has a programmable parameter scheme which makes it possible to read and write 3 1/2 inch variable and fixed speed drives, as well as standard 5 1/4 inch drives. Additionally, there is a plus/minus rate multiplier to correct for symmetry and frequency errors. The use of half clock circuits to provide half clock resolution in the signal being written to and read from the disk is provided with the capability of operating at continuously variable clock speeds and data rates dynamically programmable by the computer. <IMAGE>

Title: Electronic vehicle signalling device to train or remind driver to use mirror regularly
Inventor: GRICE DAVID DOWNING
IPC: B60K35/00
Filed: 1993-07-21
Abstract: Drivers should check their mirror/s regularly to keep up to date with the danger developing or happening to the rear. Drivers find this necessity, for example every 7 seconds, a difficult procedure to adopt. The eyes find this disciplined movement unnatural - the brain is not equipped with a timing device - therefore the training for correct mirror use is difficult to achieve. Because of the sensitivity of the eyes the device will attract/remind the eyes of the driver for regular mirror use. The LED light (3) is positioned on the binnacle of the vehicle directly in front of the driver. Power is derived in this instance from the cigar lighter socket (8) and a control box regulates the timing (I) and intensity (5) of the light, predetermined by the driver. <IMAGE>
