Abstract: A magnetic device may include a magnetic structure, a device structure, and an associated circuit. The magnetic structure may include a patterned layer of material having a predetermined magnetic property. The patterned layer may be configured to, e.g., provide a magnetic field, sense a magnetic field, channel or concentrate magnetic flux, shield a component from a magnetic field, or provide magnetically actuated motion, etc. The device structure may be another structure of the device that is physically connected to or arranged relative to the magnetic structure to, e.g., structurally support, enable operation of, or otherwise incorporate the magnetic structure into the magnetic device, etc. The associated circuit may be electrically connected to the magnetic structure to receive, provide, condition or process of signals of the magnetic device.

Abstract: Actuators are used to move a variety of objects to desired positions. It is generally desirable that they can do this quickly without exhibiting overshoot or ringing. Some actuators are required to respond very quickly and examples of these are voice coil drivers used to move lenses in autofocus cameras provided in everyday devices such as smart phones and tablets. A rapid two step controller scheme had already been disclosed by Analog Devices Inc. While the scheme works well, it can only be used reliably if the resonant frequency of the actuator is known to within 2 or 3%. The inventors have discovered that the resonant frequency of an actuator unexpectedly changes as a function of position. This disclosure provides ways of modifying the control scheme to cope with changes in resonant frequency.

Abstract: A blood oxygenation sensor is provided comprising: a first current-powered light source to produce light having a first wavelength; a second current-powered light source to produce light having a second wavelength; a light sensor to produce a current signal having a magnitude that is indicative of intensity of light incident upon it; a current level driver circuit that includes a current source configured to couple the current source to alternatively provide current to one of the first current-powered light source and the second light current-powered light source; a processor configured to predict times of occurrence of one or more first time intervals in which arterial volume at a tissue site is at one of a maximum and a minimum; wherein the processor is configured to control the current source, to provide a first pattern of higher power-dissipation current pulses to the first and second current-powered light sources during the first time intervals, and to provide a second pattern of lower power-dissipation current pulses to at least one of the first and second current-powered light sources during second time intervals.

Abstract: Aspects of the embodiments are directed to time-of-flight (ToF) imaging systems and method for image processing. The ToF imaging system can include a depth sensor; a light steering device; a photodetector; and an image processor. The ToF imaging system can be configured to acquiring a first image of a scene by the photodetector; identifying one or more regions of interest of the scene from the first image; and capturing a depth map of at least one of the one or more regions of interest.

Abstract: Aspects of the embodiments are directed to a time-of-flight imaging system and methods of using the same. The time-of-flight imaging system includes a light emitter comprising at least one one-dimensional array of laser diodes; a photosensitive element for receiving reflected light from an object; and a light deflection device configured to deflect light from the light emitter to the object. In embodiments, the time-of-flight imaging system includes a lens structure to deflect emitting light from the laser diodes at a predetermined angle towards a light steering device.
