Latest Patents

One of his latest patents is focused on a mobile terminal interface. This invention includes a microphone that is connected to a current source when the flip portion of the mobile terminal is open and is disconnected when the flip portion is closed. The mobile terminal can infer the position of the flip portion based on the state of the microphone's current supply circuit. This technology allows for the detection of the current flowing through the circuit or a voltage drop across a supply resistor. Additionally, an on-hook/off-hook button can be integrated into a hands-free accessory without increasing the number of signal lines between the accessory and the mobile terminal. This is achieved by connecting the button to a switch in the microphone signal line, which selectively creates an open in the line, resulting in an off-hook condition.

Another patent involves a portable communication device with a movable element and a sensor for detecting its position. This device features an apparatus housing with a movable element attached and a sensor that detects the position of the movable element in relation to the housing. The communication device also includes an electrodynamic device with a magnet. The sensor detects the magnetic field from the magnet and provides an output relative to the housing. A device within the movable element conducts the magnetic field from the electrodynamic device to the sensor.
