Abstract: An active filter reduces Electro-Magnetic Interference (EMI) created by current flowing through a power line. The active filter connects to the power line at a single node through a connection capacitor. A sense current flows through the connection capacitor when the power line current changes. This sense current is applied to a gain control circuit having cross-coupled PNP transistors that drive currents to both terminals of a variable capacitor. The variable capacitor converts these currents to a voltage that is injected back into the power line through the connection capacitor as an injected compensation voltage that compensates for the sensed current.

Abstract: A wireless power transmitter has electromagnets and a transmitter coil mounted on a moving plate. Current in the main DC circuit is switched into the electromagnets by transistors that control the amount and direction of current through the electromagnets to control the strength and polarity of electromagnetic fields generated by the electromagnets. A controller initially drives a high gate voltage onto transistors to cause the electromagnets on the transmitter to generate a maximum attractive force with magnets on the receiver, causing the moving plate to move the transmitter coil into closer alignment with the receiver coil. A power factor is measured on both receiver and transmitter to estimate the power transfer efficiency. The controller then reduces the gate voltage by a step size and the power factors are measured again. The gate voltage continues to be adjusted to optimize the power transfer efficiency until reaching a maxima.

When the telescopic tube is pulled backward, the movable bearing is not actuated.

Abstract: An active filter reduces Electro-Magnetic Interference (EMI) created by current flowing through a power line. The active filter connects to the power line at a single node through a connection capacitor. A sense current flows through the connection capacitor when the power line current changes. This sense current is applied to a non-inverting input of an op amp to drive a power amplifier circuit through a filter capacitor. The power amplifier circuit increases the current drive of the op amp to charge a transfer capacitor that converts the power amplifier output current to a transfer voltage. The transfer capacitor is connected to the connection capacitor so that the transfer voltage is injected back into the power line through the connection capacitor as an injected voltage that compensates for the sensed current. Op amp gain is adjustable by variable resistors that connect to the inverting input of the op amp.

Abstract: A computer-implemented technique is described herein for using a machine-trained model to identify individual objects within images. The technique then creates a relational index for the identified objects. That is, each index entry in the relational index is associated with a given object, and includes a set of attributes pertaining to the given object. One such attribute identifies at least one latent semantic vector associated with the given object. Each attribute provides a way of linking the given object to one or more other objects in the relational index. In one application of this technique, a user may submit a query that specifies a query object. The technique consults the relational index to find one or more objects that are related to the query object. In some cases, the query object and each of the other objects have a complementary relationship.
