Patent GB-2348750-A (GB)
Title: Induction cooking hob
Inventor: AKEL DOMINIQUE
IPC: H05B6/04
Filed: 2000-04-04
Abstract: An induction heater F1 for a cooker hob with a number of inductances L1, L'1 supplied from generators G1, G2 controlled by a controller CU and operating at the same frequency or harmonics of that frequency. In a low power operation (see fig 1) the inductance L1 alone is used to heat the induction heater F1 from generator G1 with the second generator G2 being used to heat an inductance L2 in a second induction heater F2. In high power operation the controller CU actuates a switch K1 to supply power from generator G2 to the inductance L'1 in the first induction heater. Operating the generators at the same or harmonic frequencies avoids beat frequencies and allows the use of modular low power generators. In an alternative embodiment (see figs 2 and 2a) the inductances L1 and L'1 can be connected in series so that currents flowing through the inductances are identical. In a further improvement the number of capacitors used in the circuit can be reduced with the series connection (see fig 3 and 3a). The heater capacity can be extended further by increasing the number of inductances and generators in the heater and operating each of the inductances independently (see figures 4 and 5) with an adjustable duty cycle for a pulse width modulation (PWM) control.

Title: Electrical stimulation of the leg to treat bilateral foot drop
Inventor: SWAIN IAN DOUGLAS
IPC: A61N1/36
Filed: 2000-08-30
Abstract: A leg muscle stimulator for treating a patient with drop foot is controlled partially by a foot pressure switch 100 for sensing foot rise or foot strike. The control circuitry 40 of the switch has adaptive characteristics responding to changes in the resistance characteristics of said switch means by adjusting a corresponding response threshold. The simulator comprises first and second stimulation electrodes 38 40 for attachment to the leg to apply an electrical stimulus. To treat bilateral foot drop, a two-channel stimulator offers various possibilities for controlling the signals to be supplied to different muscle groups. For example : a signal pathway between the first and second channels allows the supply of stimulation pulses in one channel to be controlled by the state of switch means associated with the other channel, or the supply of stimulation pulses in one channel may be controlled by the state of activity of the other channel. In a different arrangement, the first channel may time-out the stimulation pulses after a predetermined period and the second channel may have no or disabled timer means so that supply of stimulation pulses is continuous in a predetermined state of limb position according to responsive switch means associated with that channel.

Title: Electro-Optic Modulator
Inventor: VONSOVICI ADRIAN PETRU
IPC: G02F1/025
Filed: 2001-02-22
Abstract: An electro-optic device includes a semiconducting layer 12 in which is formed a waveguide 10 a modulator formed across the waveguide comprising a p-doped region 20 to one side and an n-doped region 18 to the other side of the waveguide, wherein at least one of the doped regions extends from the base of a recess 36, 38 formed in the semiconducting layer. In this way, the doped regions can extend further into the semiconducting layer and further hinder escape of charge carriers without the need to increase the diffusion distance of the dopant and incur an additional thermal burden on the device. In an SOI device, the doped region can extend to the insulating layer 14. Ideally, both the p and n-doped regions extend from the base of a recess, but this may be unnecessary in some designs. Insulating layers can be used to ensure that dopant extends from the base of the recess only, giving a more clearly defined doped region. The (or each) recess can have non-vertical sides, such as are formed by v-groove etches, A combination of a vertical sidewall at the base of the recess and a non-vertical sidewall at the opening could be used.
