摘要： Systems and methods for camera modules having a movable lens barrel, allowing a maximum lens diameter with minimal outside dimensions are disclosed. At least one single linear actuator is moving the lens barrel. Each actuator is deployed in an own corner of the camera module. The moving lens barrel is guided by rolling elements bearings. The actuator comprises a stator, comprising one or more coils wrapped around a rod of magnetic metal and an anchor comprising one or more permanent magnets, which are tightly attached to the lens barrel. An offset between the longitudinal center line of magnets of the anchor and the center of the stator generates a permanent force pushing the lens barrel in direction of the stator of the motor and consequently pushes protrusions on the lens barrel onto the rolling elements bearings, thus preventing the bearings to fall apart in case of a mechanical shock.

摘要： Circuits and methods system for a DC-to-DC conversion using the inductance of a motor coil are disclosed. The invention is especially applicable for mobile electronic devices having a motor and requiring a DC-to-DC conversion. By using the coil of the motor for DC-to-DC conversion and for the purpose of a motor no space for an additional coil is required. For motor control an H-bridge arrangement is provided allowing motor movement in both directions, to brake and free run. By adding two diodes and a capacitor and modulation of a switch of the H-bridge a DC-to-DC conversion has been made possible.

摘要： An intelligent light source for use with the test of a digital camera module provides a plurality of shapes of light. A fast light pulse is created with turn-on and turn-off transitions less than or equal to one microsecond. Other waveform shapes comprise a ramp and a sinusoid, and all shapes can be made to occur once or repetitively. The magnitude of the light has a range from 0.01 LUX to 1000 LUX, and the ramp has a ramp time that has a range from microseconds to 100 ms. The light comprises of a plurality of colors created by serial connected strings of LED devices, where the LED devices in a string emit the same color. The light emanating from the light source is calibrated using a photo diode and the control of a tester by adjusting offset voltages of a DAC controlling a current through the LED strings.

摘要： Systems and methods to position most precisely a lens system of an optical device are disclosed. Embodiments of these electrical sensors comprise capacitive sensors, inductive sensors and resistive sensors to measure the actual position of a lens system with a precision of at least 1 μm. Read-out circuits using double-correlated sampling structures are providing the position signals from the electrical sensors to a controller. The controller compares the actual position signals with a set-signal representing a target position of the lens signal and issues a signal to a motor to get the lens system moved to the target position. A variety of motors/actuators can be used to move a slider carrying the lens system to the position desired.

摘要： A test handler is controlled by a tester to transport, select, focus and test miniature digital camera modules. The modules are loaded onto a transport tray and moved on a conveyer to a robot. The robot selects the untested modules from the tray an alternately places the modules into two test stations. A first test station focuses and tests a first module while the second test station is loaded with a second module, thus burying the handling time for the modules within the test time. The robot returns tested modules to the transport tray, and when all modules on the tray are tested, moves the tray out of the test handler. A second tray with untested modules is positioned at the robot while the tested modules of the first tray are being focus fixed and sorted into part number bins. The overlap of operations buries handling time within the focus and test time so that the limitation of total test time is depending on focus and test operations.

摘要： A circuit and method are given, to realize a loudness control for mobile phone earpieces and speakers with the help of a proximity sensor, which is realized as an infrared photo-electric guard circuit, where only very few external parts are needed. As a novelty here, the necessary photo sensors are integrated onto a single chip. To form the photodiodes within a single IC together with the other circuit elements are much less expensive. Using the advantages of that solution the circuit of the invention is manufactured with standard CMOS technology and only very few discrete external components. This solution reduces also power consumption and manufacturing cost.

摘要： Circuits and related methods for switched step-down and boost DC-to-DC converters have been achieved. Said DC-to-DC converters comprise an inductor current sensing and limiting circuit to prevent the inductor current to exceed a defined limit. Said current sense circuit is using the voltage on the on-state source-to-drain resistance of a power switch to monitor the inductor current. Said voltage is amplified and serves as input of a regulator. Said regulator, being connected via one or more gate controllers to the gates of said power switches, controls the ON/OFF state of said power switches by pulse-width-modulation. Said power switches are switched ON/OFF if the current exceeds a defined limit. After a defined time period said power switches are switched on again. Gate controllers keep the power switch in an operating region having a stable source-to-drain resistance while said power switch is ON. The ON/OFF duty cycle of said power transistor switches is set in a way that the difference between charge/discharge energy is kept on a minimum.

摘要： A test system for digital camera modules used in consumer electronics, e.g. cellular phones and PDA's is shown. The test system comprises of a tester and a module handler that is aimed at reducing test time by an order of magnitude. The Test system has an image-processing unit that uses N-parallel processor to reduce the computation time on a test image by approximately the number of parallel processors. The handler is controlled by the tester to select, focus and test small digital camera modules. There are two test stations in the handler, where a first test station performs tests on a first camera module while a second test station is loaded with a second camera module, thus burying the loading time within the test time.
