Embodiment Construction

[0046] We observed that figure 1 In a specific embodiment, the device 100 comprises, on the one hand, a keyboard 105 comprising keys 110 and voltage generating means 115 and, on the other hand, a keyboard 105 comprising voltage comparing means 125, a modification applied to the voltage comparing means 125 The electronic interface 120 of the upper threshold voltage means 130 and a central unit card 135 .

[0047] The central unit 135 card includes a power supply 140 . The central unit is, for example, a microcontroller, a digital signal processor or "DSP" (an acronym for Digital Signal Processor) or an element comprising a processor.

[0048] The voltage generating means 115 is adapted to generate a voltage when it is subjected to mechanical deformation. Preferably, the voltage generating means 115 comprises piezoelectric elements mechanically connected to the keys of the keyboard by conventional means. For example, the keypad 105 is constructed from a single sheet of materi...

Abstract

A touch-sensitive interface device includes: a touch-sensitive keypad including at least an element for generating a voltage as the effect of a mechanical deformation, and a signal processing electronic interface adapted to detect pressing and / or releasing of a voltage generator element and to go to standby after the pressing and / or the releasing of each voltage generator element. The voltage generator element preferably includes a piezoelectric element. In embodiments, the electronic interface includes at least one voltage comparator device, the generation of a parameterable threshold voltage to which the voltage comparator device compares the voltage at the terminals of a voltage generator element, and a card including a central processor unit and its power supply unit. The parameterable threshold voltage can be increased or decreased to detect positive and negative peaks of at least one voltage generator element respectively caused by pressing or releasing at least one voltage generator element.

Description

technical field [0001] The present invention relates to touch interface devices and methods. The present invention is particularly applicable to safeguarding the battery life of electronic products equipped with a touch human-machine interface (“IHM”) and not connected to an uninterruptible power supply. Background technique [0002] Electronic solutions dedicated to touch interfaces consume too much current in order to guarantee a battery life of at least two years for products not connected to an uninterruptible power supply. [0003] Typically, mobile electronic products that are equipped with a touch interface and are not connected to an uninterruptible power supply, such as digital walkmans, mobile phones, personal digital assistants and geolocation systems, use rechargeable batteries. With regard to touch interface technologies, these are known as "capacitive" technologies, which are low-power, however, for at least two years, without doing things such as replacing th...
