Problems solved by technology

This situation has the disadvantage that the hand-held device is often in active mode also when not in use (as for example in a computer mouse), since manual activation or deactivation of the active mode seems relatively inconvenient or simply forgotten
Therefore, the desired improvement of maximum energy efficiency is not achieved

Embodiment Construction

[0084] figure 1 An electric hand-held device comprising a detection device according to the invention is shown in cross-section, wherein the hand-held device is gripped by a hand H. FIG. The transmitting electrode SE is arranged at a side wall of the electric hand-held device, and the receiving electrode EE is arranged at a side wall arranged opposite to this side wall. In this case, the transmitting electrode SE and the receiving electrode EE are arranged at mutually opposite side walls of the hand-held device, such that during the gripping of the housing by the hand, both electrodes are at least partially covered by the hand.

[0085] The emitter electrode SE is coupled to a signal generator G which generates a low-frequency alternating voltage. The emitter electrode SE is loaded with this alternating voltage. In doing so, an alternating electric field 20 is formed at the emitter electrode SE. The alternating voltage provided by the generator G has a frequency approximate...

Abstract

A device for an electric hand-held device for detecting the hand-held device being clasped by a hand, has at least one transmitting electrode, which can emit an alternating electric field, and at least one receiving electrode, in which the alternating electric field can be coupled at least partially, wherein the at least one transmitting electrode and the at least one receiving electrode can be arranged on the hand-held device such that each of them is at least partially covered by the hand when the hand-held device is being clasped by the hand. When the hand-held device is being clasped by the hand, a first portion of the alternating electric field emitted by the transmitting electrode can be coupled via the hand into the receiving electrode, wherein at least the first portion of the alternating electric field is a characteristic representative of the hand-held device being clasped by the hand.

Description

technical field [0001] The invention relates to a device for an electric hand-held device for detecting a hand-held grip of the hand-held device, so that during the hand-grip of the hand-held device, the hand-held device can eg be transferred from a sleep mode to an active mode. Furthermore, the invention relates to an electric hand-held device comprising a detection device according to the invention, and a method for detecting a grip of a hand on an electric hand-held device. Background technique [0002] In the prior art, the technology of electric devices and in particular electric hand-held devices requires improved energy efficiency. In particular, in the case of portable hand-held devices, like for example remote controls or cell phones, which provide batteries or accumulators for energy supply, this requirement exists in an enhanced manner, since the batteries or accumulators are quickly depleted. Increased energy efficiency will reduce current consumption, which lea...
