Abstract: An electric field object sensing system uses a charge pumping circuit to provide a voltage over a capacitor that varies dependent upon the capacitive coupling between a transmitter electrode and a receiver electrode. The output of the charge pump is preferably fed to a high impedance read-out means, such as an analog-digital converter (ADC). The system is preferably implemented in CMOS and integrated in control circuits of electronic products.

Abstract: A user input system (40) in which an output from a cross-capacitance object sensing system (30) (also known as an electric field object sensing s system) is combined with an output from a touchscreen device (15). An output from the user input system (40) may comprise position information derived from the cross-capacitance object sensing system (30) and indications of touch events derived from the touchscreen device (15). Another possibility is for sensing signals (S1, S2, S3,S4) derived from the cross-capacitance object to sensing system (30) to be processed in combination with position information derived from the touchscreen device (15) to provide updated parameters (P1, P2, P3, P4) for an algorithm used to determine position information from further sensing signals (S1, S2, S3, S4) derived from the cross-capacitance object sensing system (30).

Abstract: A computer tower stand includes a structure including a shelf adapted to support a computer tower chassis, and a main compartment configured to conceal and store peripheral computer devices such as cables that extend from the computer tower chassis and various other electrical devices utilized in conjunction with the computer system. A speaker compartment is formed in the main compartment and configured to house and support a speaker assembly.

Abstract: A color display system including a cathode ray display tube (10) of the kind which has an electron multiplier (16) arranged adjacent a luminescent screen (14) comprising a repeating pattern of three different color phosphor elements and pairs of color selection electrodes (38, 40) associated with each channel of the multiplier operable to control the direction of the electron beam from the channels for color selection purposes uses a switching bridge circuit comprising semiconductor switching device (52, 54, 56, 58), e.g. MOSFETs, connected between voltage supplies for switching the voltage applied to each one of the pair of electrodes between three respective levels in synchronism to achieve a predetermined color selection sequence. The semiconductor devices are controlled by synchronized waveforms from a pulse generating circuit (86) via optocouplers (88) enabling the switching bridge circuit to be floated at a high potential.
