Patent GB-2296373-A (GB)
Title: Semiconductor device
Inventor: FROST JONATHAN E F
IPC: H01L29/812
Filed: 1994-12-14
Abstract: A non-linear transconductance device 1 has a series of semiconducting layers containing a lower mobility channel 27 in closer proximity to a control gate 3 than a higher mobility channel 29. The device 1 has a base structure 7 having a first doped layer 35 and optionally a second undoped or partially doped layer 33. It also has a surface structure 5 having a first doped layer 27 of the same conductivity type as the layer 35, and a second undoped or partially doped layer 29. The second layer 29 is adjacent to the layer 33 of the base structure 7. When the doped layers 35, 37 are n-type, the base structure 7 is made of material having a higher conduction-band-edge than that of the surface structure 5. If the doped layers 35, 37 are p-type then the base structure material has a lower valence-band-edge than that of the surface structure 5. A gate 3 overlies the surface structure 5. The transconductance is believed to increase by shifting the carrier's wavefunction from the lower mobility channel to the higher mobility channel by an externally applied gate voltage. The device can operate as, for example, a transistor or frequency multiplier. <IMAGE>
Patent GB-2285375-A (GB)
Title: Digital quadrature amplitude modulation
Inventor: WILLIAMS RICHARD GUY CARRINGTO
IPC: H04L27/26
Filed: 1994-12-23
Abstract: Data are transmitted using multiple carriers modulated by quadrature amplitude modulation. In general, the carriers carry different numbers of bits, to exploit the fact that the properties of a transmission path are more favourable to carriers at some frequencies than to those at others. The bit allocation process is made closer to optimum by permitting allocation of a non-integer number of bits to a carrier. Input bits are grouped for several carriers and this binary representation is converted to a number representation in which the base of each digit corresponds to the number of points in the QAM constellation for a respective carrier (or to this number divided by a power of two). <IMAGE>
Patent GB-2296908-A (GB)
Title: Stairlift
Inventor: SIMMONDS JAMES ANDREW
IPC: B66B9/08
Filed: 1995-01-10
Abstract: A stairlift comprising an elongate track (10, Fig 1) upon which a driven chair or platform is mounted, and a section (10a) of the track being movable selectively between aligned and misaligned positions thus to avoid obstructing, for example, a doorway (14). The movable track section (10a) is raised by a gas strut (28) and lowered by a linear actuator (35). Locking bars (24) act upon compression springs (50) to absorb the driving force of actuator (35) in the event of an obstruction. Movement of the bars (24) against the springs (50) is arrested when a micro switch (46) is actuated to stop a driving motor (38). Thus drive to the track section (10a) is arrested safely in the event of an obstruction.
