    Abstract: An optical sensor circuit comprises an optical sensor (DET) designed to provide a sensor signal indicative of light incident on the optical sensor (DET). A clock terminal (CLK) is used to receive a clocked control signal comprising high and low states. A controller unit (CU) is connected to the optical sensor (DET) and to the clock terminal (CLK). The controller unit (CU) is designed to process the sensor signal as a color signal (CTS) in a first mode if the clocked control signal is in high state, and process the sensor signal as an ambient light signal (ALS) in a second mode if the clocked control signal is in low state, and further designed to generate a driving signal (PWM) to drive a light emitting device (LED) to be connected at a control terminal (OUT). The driving signal (PWM) depends on the color and ambient light signal (CTS, ALS).

    Abstract: A circuit arrangement for an optical monitoring system comprises a driver circuit configured to generate at least one driving signal for driving a light source and a detector terminal for receiving a detector current. The circuit arrangement further comprises a current source configured and arranged to generate at the detector terminal a reduction current. The reduction current has an amplitude which is given by a base value whenever none of the least one driving signal assumes a value suitable for activating the light source and by a sum of the base value and a reduction value otherwise. The circuit arrangement also comprises a processing unit configured to generate an output signal depending on a combination of the detector current and the reduction current.

    Abstract: A control system for a gesture sensing arrangement with at least one sensor operates the sensor in a proximity mode. The control system receives data sets generated by the sensor and based on these data sets determines whether an object is present in a vicinity of the sensor. When an object is detected in the vicinity the control system operates the sensor in a gesture mode. Based on further data generated by the sensor the control system determines an end of a gesture, and operates the sensor in the proximity mode.

    Abstract: A flash driver to limit a load current for a flash comprises a dc/dc converter (DCDC) having a first input (IN1) to receive an input voltage (Vin) and an output (OUT) to supply an output voltage (Vout). The dc/dc converter is designed to convert the input voltage (Vin) to the output voltage (Vout). Furthermore the flash driver has an adjustable current source (Iadj) connected between the output (OUT) and a load terminal (LT). A first control unit (CTRL—1) is connected to the first input (IN1) and coupled to the adjustable current source (Iadj), and is designed to compare the input voltage (Vin) to a threshold (Vth) and, if the comparison indicates the input voltage (Vin) being smaller than the threshold value (Vth), adjust the adjustable current source (Iadj) such that the input voltage (Vin) is equal or greater than the threshold value (Vth). A second control unit (CTRL—2) is coupled to the adjustable current source (Iadj) and the dc/dc converter (DCDC) and is designed to detect a voltage drop over the adjustable current source (Iadj) and to set the dc/dc converter (DCDC) to control the conversion of input voltage (Vin) to the output voltage (Vout) depending on the detected voltage drop.
