Abstract: The present invention relates to a device for providing neuromuscular stimulation. The device comprises a positive electrode, a plurality of negative electrodes, a non-conductive substrate and a control unit for activating the electrodes. The control unit of the device activates the negative electrodes in a predetermined sequence, so as to deliver electrical stimulus to a user, wherein the predetermined sequence is repeated with an increasing level of stimulus until a predetermined outcome is achieved. Additionally each negative electrode of the devices comprises at least one conductive track mounted on the non-conductive substrate wherein at least one pair of negative electrodes overlap such that the conductive track or tracks of a first negative electrode of the pair overlap with the electrode footprint, but not the conductive tracks, of a second negative electrode of the pair.

Abstract: A neuromuscular stimulation device is described having a plastic casing housing a printed circuit board bearing control electronics, with the casing including an external integral flexible portion which is capable of being flexed into the interior of the casing so as to cause an electrically insulative substrate on which is carried an electrically conductive pathway to be pushed into contact with the PCB in order to complete an electrical circuit. Such a switch is relatively inexpensive to produce, as it has few moving parts, can be formed in a usual manufacturing process, and is robust.

Abstract: A neuromuscular stimulator device is described having a plastic casing housing control electronics which are maintained in contact with a power source by a metal retaining clip. The casing includes an integral cover which may be opened by breaking lines of weakness formed in the cover. The cover and clip are of such relative sizes and shapes so that once the cover is open, the clip may only be removed from the casing by deforming the clip. This deformation will ensure that the clip and other components cannot be replaced back in the casing, such that the device cannot easily be reused. In addition, the cover is not replaceable, due to the broken portions of the casing.

Abstract: This invention relates to a multi-cycle power generator. More specifically, the invention relates to a power generator having a heat pump cycle and at least a hot power gener-ating cycle, the cycles being configured relative to one another to transfer heat there between two or more times in a single cycle thereby to recover energy through the reuse of unused heat energy that is typically discarded in conventional ther-modynamic cycles. The multi-cycle power gener-ator includes a heat pump cycle and a hot power cycle, wherein at least a pair of heat exchangers of the hot power cycle are common with a pair of heat exchangers of the heat pump cycle. The multi-cycle power generator may further include a cool power generating cycle In combination with the heat pump and hot power generating cycles.

Abstract: A novel method of enhancing power amplifier linearity is disclosed. The invention is for use within a transceiver system and provides a method in the digital domain for predistorting a digital modulated signal to compensate for the non-linearity properties of the power amplifier and other components within the transmitter system. The RF output signal of the transmitter circuit is sampled and the corresponding amplitude and phase are detected using a receiver circuit. In dependence upon the amplitude and phase information, a look-up table is indexed to select the predistortion data and predistortion of the digital modulated signal occurs within the predistortion circuit.

Abstract: A loop impedance meter is provided for testing an A.C. electrical mains supply. The meter comprises an electronic control circuit for connecting a load resistance intermittently between the A.C. mains supply terminal and the earth terminal to measure the potential difference between those terminals and to provide an indication of the loop impedance of the A.C. mains supply from that potential difference. The control circuit is arranged to allow a train of short pulses of current to flow through the load resistance and the loop, the pulse train beginning its sequence with a first train of pulses for preconditioning any residual current device-present in the loop to temporarily desensitize it. The first train of pulses is followed by one or more measurement pulses, the pulses of the first train being of generally increasing width.

Abstract: A rotor assembly for counting sheets in a stack has a support on which is rotatably mounted a rotor such that the rotor engages an edge region of the stack. The rotor has a plurality of helical transfer grooves through which sheets are transferred one at a time from one side of the rotor to the other. A foot bears on the rotor and has a port which, as the rotor rotates, comes into and out of communication with further ports on the rotor each leading to a respective groove, whereby air is drawn in a timed relationship through the rotor to assist the transfer of sheets through the helical grooves. The rotor is movable axially with respect to its support and there is a detector arranged to detect the position of the foot with respect to the support thereby to give an output indicative of the position of the rotor with respect to the support.

Abstract: A sheet counter has a blade (13) for insertion between adjacent sheets of a stack thereof, and a pin (15) which orbits around the blade to transfer sheets from one side of the blade to the other. A carrier (37) defines three axes disposed in a generally triangular arrangement, the pin (15) being mounted on one of the axes, and the carrier being coupled to a crank (36) about another axis. A link (42) is pivoted at one end to the carrier (37) and at its other end to a fixed part of the counter. As the pin (15) orbits around the blade (13) on rotation of crank (36), the blade is oscillated about an axis adjacent the edge inserted furthest into the sheet stack by a crank (30) and connecting rod (31), driven synchronously with crank (36). Suction is applied in a timed manner to a hole (45) in the blade (13), to assist the separation of the sheets one at a time, before the transfer thereof to the other side of the blade by pin (15).
