Problems solved by technology

[0005] Tests have shown that the wake detector mentioned in GB 2398138A has the disadvantage that it cannot reliably detect a hand approaching the wake detector
In most adverse conditions, even false detection of hand approach wakes up the detector

Embodiment Construction

[0039] Figure 1 shows a mobile phone comprising a proximity sensor known from the state of the art. Such a proximity sensor is eg known from the above mentioned GB 2398138A. The electrode E close to the sensor is arranged on the left casing wall of the mobile phone. When the hand is close to the phone or electrode E, the capacitance at electrode E changes. This change in capacitance can be analyzed by an analysis device coupled to the electrode E. However, this is disadvantageous, especially in the case of battery-operated devices and in the case of very low capacitive coupling between the user's hand and the electrode E, when the hand is close to the electrode E, the change in the coupling capacitance is also very low. Small, this can mean that approach may not be reliably detected.

[0040] Reference below Figure 2 to Figure 8 The present invention is described in more detail. According to the invention, the sensor device operates in a first mode of operation and in a ...

Abstract

The invention relates to a sensor device for detecting the grip of a handheld device by one hand. Furthermore, the invention relates to a method for detecting the grip of a hand-held device by a hand, wherein the hand-held device comprises a sensor device according to the invention for detecting the grip. Furthermore, the invention relates to a hand-held device comprising a sensor device according to the invention. The sensor device comprises at least one first electrode and at least one second electrode. The first electrode is operable in a first mode of operation. The second electrode is operable in the first mode of operation and in a second mode of operation. In the first mode of operation, the capacitive coupling between the first electrode and the second electrode is analyzed. In the second mode of operation, the capacitive loading of the second electrode is analyzed against a reference ground.

Description

technical field [0001] The invention relates to a sensor device for detecting the grip of a handheld device by one hand. Furthermore, the invention relates to a method for detecting the grip of a hand-held device by a hand, wherein the handheld device comprises a sensor device according to the invention for detecting the grip. Furthermore, the invention relates to a hand-held device comprising a sensor device according to the invention. Background technique [0002] There has long been a desire to reliably detect a hand's grasp of a handheld device, especially an electric handheld device. In order to reliably detect the grasping of a hand-held device by one hand, the hand-held device, such as a cell phone, may have an additional function being performed depending on whether a hand is gripping the hand-held device or not. For example, when the phone is held in one hand, the phone can be turned on and / or the key lock can be unlocked. When the handset is released, the handse...
