  • Patent number: 9921598
    Abstract: A current mirror includes an input transistor and an output transistor, wherein the sources of the input and output transistor are connected to supply voltage node. The gates of the input and output transistor are connected through a switch. A first current source is coupled to the input transistor to provide an input current. A copy transistor has a source connected to the supply node and a gate connected to the gate of the input transistor at a mirror node. A second current source is coupled to the copy transistor to provide a copy current. A source-follower transistor has its source connected to the mirror node and its gate connected to the drain of the copy transistor. Charge sharing at a mirror node occurs in response to actuation of the switch and the source-follower transistor is turned on in response thereto to discharge the mirror node.

  • Patent number: 9923400
    Abstract: A battery charger operates in a current regulation mode and a voltage regulation mode. A value of the voltage on the battery being charged is sensed and compared against a target voltage value. The current regulation mode is active during charging while the sensed voltage is less than the target voltage value. When the sensed voltage reaches the target voltage value, the voltage regulation mode is enabled and the current regulation mode is inhibited.

  • Patent number: 9918667
    Abstract: A universal electrochemical micro-sensor can be used either as a biosensor or an environmental sensor. Because of its small size and flexibility, the micro-sensor is suitable for continuous use to monitor fluids within a live subject, or as an environmental monitor. The micro-sensor can be formed on a reusable glass carrier substrate. A flexible polymer backing, together with a set of electrodes, forms a reservoir that contains an electrolytic fluid chemical reagent. During fabrication, the glass carrier substrate protects the fluid chemical reagent from degradation. A conductive micromesh further contains the reagent while allowing partial exposure to the ambient biological or atmospheric environment. The micromesh density can be altered to accommodate fluid reagents having different viscosities. Flexibility is achieved by attaching a thick polymer tape and peeling away the micro-sensor from the glass carrier substrate.

  • Patent number: 9921058
    Abstract: Methods and systems for dynamic tracking of on-stage objects using microelectromechanical systems (MEMS) presented herein do not require illumination to track a randomly moving object and are easily configurable for various stage sizes and for stages movable relative to the ground. In some instances, a tracking method includes determining an initial state of an MEMS motion tracker carried on a dynamic object, such as a performer. Acceleration and orientation information gathered by the motion tracker is monitored. A change of state in response to the monitored acceleration and orientation information is then determined. An instant state is calculated using the change of state and the initial state. Actuation signals based on the calculated instant state are generated for actuating a gimbal. The gimbal faces a device supported thereby toward the dynamic object.
