Abstract: A hand held spray dispenser in which air and liquid are pressurised towards a mixing chamber by energy generated by a manual activation element that is rotated with a unidirectional twist to energise one or more energy storage bodies, energy from which is released to generate sufficient air pressure and air flow and sufficient liquid flow for a spray to be formed from the air-liquid mixture.

Abstract: A hand held spray dispenser in which air and liquid are pressurised towards a turbulence chamber and wherein air is introduced into the liquid adjacent to an inlet orifice of the turbulence chamber and the mixture passes through the inlet orifice into the turbulence chamber before being expelled through an exit orifice.

Abstract: A monitoring circuit for a CES element is provided. The circuit includes a control circuit and an output circuit. The control circuit is configured to vary a control signal provided to the CES element. The control signal may be varied for determining an impedance state of the CES element. The output circuit provided an output signal in dependence on the determined impedance state of the CES element.

Abstract: An integrated circuit and method for testing memory on the integrated circuit are provided. The integrated circuit has processing logic for performing data processing operations on data, and a plurality of memory units for storing data for access by the processing logic. Further, memory test logic is provided to perform a sequence of tests in order to seek to detect memory defects in the memory units. The memory test logic comprises a plurality of test wrapper units, each test wrapper unit associated with one of the memory units and being operable to execute tests on the associated memory unit, and a test controller for controlling performance of the sequence of tests by communicating with each of the test wrapper units to provide test data defining each test to be executed by that test wrapper unit.

Abstract: In an environment wherein a microprocessor can operate at several different voltage levels depending upon the instantaneous throughput of the microprocessor, a memory and memory adjustment circuit that permits operating the memory at a plurality of voltages in response to the microprocessor is disclosed. The memory and memory adjustment circuit sense the instantaneous operating voltage of the microprocessor and adjust the operating voltage of the memory in response thereto. The memory adjustment circuit more particularly increases or decreases the memory's bitline sense interval in response respectively to a decrease or increase in the memory's operating voltage.
