Abstract: A clock enabling circuit for providing a gated clock signal in response to receiving clock request information is presented. The clock enabling circuit comprises a clock request input, a clock input, and a flip-flop stage. It also includes a first sub-circuitry comprising a first input being coupled with the clock request input and an output being coupled with the flip-flop stage for providing a set information to the flip-flop stage in response to the receipt of the clock request information, the flip-flop stage being configured to provide a clock enabling information in response to receiving the set information and a second sub-circuitry comprising a first and a second input, the first input being coupled with the clock input and the second input being coupled with the flip-flop stage, the second sub-circuitry comprising an output for providing the gated clock signal in response to receiving the clock enabling information.

Abstract: Systems and methods for providing a differentiation of two identical slave devices on a same I2C bus without any hardware (e.g. additional ID pins) or software overhead are disclosed. Each identical slave device is connected to the SDA/SCL lanes by interchanging its SDA/SCL ports. It is up to the slave device to detect its signal connectivity to the SDA/SCL lanes of the I2C bus. The slave devices detect the signal connectivity by interpreting the I2C transfer in normal and interchanged connectivity.

Abstract: Systems and methods using the same to achieve a precise timing of a camera shutter, which can be used also for a controllable aperture, are disclosed. A bidirectional linear motor having two coils driving the shutter blades can also be used as a position sensor. A movable iron is driven dependent upon currents through the coils and as the iron moves, the inductance of both coils changes. The difference of inductance of both coils indicates the actual position of the iron. Since the movable iron is mechanically connected to the entirety of shutter blades the difference of inductance indicates the actual position of the shutter blades. A read-out circuit senses the difference of inductance of both coils, which is indicating the actual position, and a control loop is comparing the inductance difference signal with a target signal in order to control the current through the coils in a way that the shutter blades are moved quickly to their target position.
