Patent GB-2157896-A (GB)
Title: Capacitive switch with inductance
Inventor: MARTINEZ ANTHONY
IPC: H03K17/975
Filed: 1985-04-11
Abstract: An improved switch of the keyboard type comprises two lower capacitive pads mounted on a base, one being connected to an input network, and the other connected to an output network. A movable key has a third capacitive pad which is in two portions 6, 7 secured to its lower surface, the portions 6 and 7 being connected together by an inductor 8. When the key is in the raised position there is only a capacitance between the two lower capacitive pads, and the output signal for a given input signal is low. When the key is in the depressed position, the inductor 8 is introduced to produce a series resonant circuit such that the series impedance of the network decreases and the output signal for the same input signal is increased. The inductor 8 is either of wound type, or is printed onto a flexible substrate together with the pads 6, 7. <IMAGE>

Title: Manufacturing insulated gate field effect transistors
Inventor: CEROFOLINI GIANFRANCO
IPC: H01L21/20
Filed: 1985-07-17
Abstract: An IGFET is made by etching to expose substrate 1 at the sides of a channel zone, and by forming on the exposed substrate 1 regions 18, 19 of epitaxial type automatically aligned with a gate electrode 11 and designed to form source and drain regions. These regions are doped by ion implantation using a comparatively low implantation energy such that the doping agent does not penetrate into the substrate. By providing the source and drain junctions on the surface of the substrate, rather than in the substrate, there are no lateral junction capacitances and the horizontal dimensions of the IGFET may be reduced, with the result that high response speeds and high intergration densities are obtained. …<IMAGE>…

Title: Determining channel quality
Inventor: BASLINGTON ANDREW COLIN
IPC: H04L1/20
Filed: 1989-06-06
Abstract: A method of assessing the quality of a data channel based on the processing of soft decision demodulation information. Using the method it is now possible to determine the Bit Error Rate (BER) of a data channel in a much shorter time than previously possible. Soft decisions within a known band of levels are measured and used instead of hard decisions. The sampling may therefore be performed over a shorter time period. The method may also be used to indicate signal to noise ratios or any other selected quality scale. <IMAGE>

Title: Disabling tag bit recognition and allowing privileged operations to occur in an object-oriented memory protection mechanism
Inventor: LAI KONRAD K
IPC: G06F21/10
Filed: 1990-09-11
Abstract: A tag bit may or may not be associated with each word read from a memory. When the tag bit is a 0 the word is a data word and when a 1 the word is a valid access descriptor. Access descriptors 30 include an object index 34 for selecting an object in the address space, and a rights field 35 specifying the permissible operations on a paged object 38 selected by the access descriptor. An access descriptor in a processor control block 28 contains a tag enable bit. An object table has stored therein object descriptors 15 for use by the addressing mechanism 10 in forming physical addresses to a page table object 44 storing page table entries 17 for use by the addressing mechanism 10 in forming physical addresses to the paged object 38. One of the access descriptors in a process control block 64 contains an execution mode bit which represents either the user mode or the supervisor mode. Logic asserts the tag signal upon the condition that the tag enable bit is in the disabled state and execution mode is set to supervisor mode. Logic responds to the tag signal and compares the page rights field 50 of the page table entry with the rights field 35 of the access descriptor 24 and asserts a fault if the access rights are inconsistent. <IMAGE>
