A carrier tape has at least two conductive rails affixed at opposite edges of the carrier tape. The purpose of the conductive rails is to provide power to smart labels mounted to the carrier tape for charging the batteries of each of the smart labels or transferring data to or from the smart labels. Holes are pierced into the conductive rails and the carrier tape to make a jagged edge at the backside of each hole in the carrier tape. The jagged edge of each of the holes of the conductive rail and the carrier tape on one layer connects with the conductive rail of the layer immediately adjacent. The smart labels are mounted to the carrier tape with an adhesive. A transport package holds a carrier tape that retains the smart labels and the conductive rails and is configured to transfer charging current or data to the smart labels.

A bidirectional voltage translator shifts a voltage level of a first voltage signal to generate a second voltage signal, and vice-versa. The voltage translator includes first and second I/O terminals for receiving and outputting the first and second voltage signals, respectively, and first and second one-shot circuits connected to first and second output transistors, respectively. The outputs of the transistors are connected to the first and second I/O terminals, respectively, and also are fed back to the respective one-shot circuits. When the output of the voltage translator has a high slew-rate, the one of the first and second one-shot circuits that corresponds to the output modulates the gate voltage of the corresponding output transistor based on the feedback signal to control the slew-rate of the output.

A system for producing a mechanical haptic pattern based on linear resonance actuator (LRA) signal is disclosed. The system includes an actuator displacement sensor, the actuator displacement sensor configured to apply an alternating measurement signal at a predetermined frequency to an actuator motor. The actuator displacement sensor configured to use a measure of a voltage across and a current through the actuator motor to determine its impedance at the predetermined frequency and determine an estimated displacement of the actuator motor using said impedance and a predetermined displacement-impedance function. The system also includes a controller configured to accept the LRA signal and the estimated displacement, wherein the controller is configured to alter the input LRA signal according to the estimated displacement to limit excursion of a moving part of the actuator motor.

Aspects of the present disclosure are directed to methods, apparatuses and systems involving voltage control using rectifying circuitry. According to an example embodiment, an apparatus includes an antenna, a capacitor, and voltage control circuitry. The voltage control circuitry includes a first rectifying circuit to rectify a wireless signal and provide the rectified signal to an output load, a second rectifying circuit to rectify the wireless signal and provide the rectified signal to the capacitor, and a control logic circuit to regulate an output voltage provided to the output load relative to a threshold value. For each rectifying cycle, the control logic circuit determines whether the output voltage is above the threshold value, enables, in response to determining that the output voltage is below the threshold value, the first rectifying circuit, and enables, in response to determining that the output voltage is above the threshold value, the second rectifying circuit.

Various aspects of the present disclosure involve communications, and more specifically wireless communications with modulation. As may be implemented in accordance with one or more embodiments, a rectifier having a plurality of active circuits operates in first and second modes to modulate signals communicated via an antenna as follows. The first mode is at least a half-active mode in which at least one of the active circuits passes the signal, and the second mode consumes less power than the first mode. A modulator modulates a waveform of the signal by selectively operating at least one of the plurality of active circuits, therein setting an impedance of the rectifier and modulating an amplitude of the signal.

Wireless power and data transfer can be implemented for powering and communicating with a variety of devices, in a manner that facilitates device access under such wireless power conditions. As consistent with one or more embodiments, wireless power and data are communicated in an apparatus such as a mobile device having a power circuit (e.g., a battery) that powers a processor under normal operating conditions, and that also operates in a low-power state (e.g., in which the processor is not operating and/or not operating using the power circuit). Power is generated using wireless power signals and used to power the power circuit and to both extract and store data from wireless data signals. With this approach, data can be transferred in a low-power state, and the processor can use the stored data upon transitioning to an on state in which the processor is active and powered by the power circuit/battery.

The present invention relates to an electric component comprising at least one first MIM capacitor having a ferroelectric insulator with a dielectric constant of at least 100 between a first capacitor electrode of a first electrode material and a second capacitor electrode of a second electrode material. The first and second electrode materials are selected such that the first MIM capacitor exhibits, as a function of a DC voltage applicable between the first and second electrodes, an asymmetric capacitance hysteresis that lets the first MIM capacitor, in absence of the DC voltage, assume one of at least two possible distinct capacitance values, in dependence on a polarity of a switching voltage last applied to the capacitor, the switching voltage having an amount larger than a threshold-voltage amount. The invention is applicable for ESD sensors, memories and high-frequency devices.
