Abstract: The invention relates to an apparatus and method for tracking energy consumption. An energy tracking system comprises at least one switching element, at least one inductor and a control block to keep the output voltage at a pre-selected level. The switching elements are configured to apply the source of energy to the inductors. The control block compares the output voltage of the energy tracking system to a reference value and controls the switching of the switched elements in order to transfer energy for the primary voltage into a secondary voltage at the output of the energy tracking system. The electronic device further comprises an ON-time and OFF-time generator and an accumulator wherein the control block is coupled to receive a signal from the ON-time and OFF-time generator and generates switching signals for the at least one switching element in the form of ON-time pulses with a constant width ON-time.

Abstract: Methods and apparatus for operating a DC-to-DC voltage converter that has a power stage that includes at least one switching transistor. The output voltage of the DC-to-DC voltage converter is monitored. If the output voltage drops below a lower output voltage threshold, a series of drive pulses is provided to the at least one switching transistor to commence switching of the at least one switching transistor. If the output voltage rises above an upper output voltage threshold, a random number of additional drive pulses is provided to the at least one switching transistor and then the provision of drive pulses to the at least one switching transistor is ceased.

Abstract: A tire pressure sensor has an RFID (radio frequency identification) device having a parallel resonant circuit including an inductor and a first capacitor for generating a first radio frequency (RF) signal for transmission to a reader circuit, and a second capacitor coupled across the parallel resonant circuit by a first switch in a first position and generating a second RF signal for transmission to the reader circuit. A capacitive pressure sensor is coupled across the parallel resonant circuit by the first switch in a second position for generating a third frequency RF signal for transmission to the reader, wherein a difference in frequency between the first and third RF signals is indicative of a pressure of a tire.

Abstract: A system includes a controller to provide at least one control output to an automated system in response to a control command received at a control input of the controller. The control output controls the operation of the automated system based on the control command. A signature analyzer generates the control command to the controller and receives an impedance signature related to a property of a material or object encountered by the automated system. The signature analyzer compares the impedance signature to at least one comparison signature to determine the property of the material or object. The signature analyzer adjusts the control command to the controller to control the operation of the automated system based on the determined property.

Abstract: An RF or other high frequency transceiver including a loopback reference channel for measurement of an absolute power level. A transmit channel in the transceiver includes a programmable power amplifier that can be controlled to operate at a selected power level, and a receive channel including a receive amplifier, mixers, filters, and analog-to-digital converters. The loopback reference channel includes a self-biased amplifier, followed by a series of buffers that generate a square wave from the received signal, and an attenuator applying an attenuation gain to the square wave. The transmit power at a programmed power level can be calculated from ratios of a measured power level of a transmitted signal as received by the receive channel to the measured power level of the transmitted signal using the loopback reference channel.

CPC classification number: H02M3/158 , H02M2001/0003
Abstract: Described examples include DC to DC converters and systems with switching circuitry formed by four series-connected switches, inductors connected between the ends of the switching circuitry and corresponding output nodes, and with a flying capacitor coupled across interior switches of the switching circuitry and a second capacitor coupled across the ends of the switching circuitry. A control circuit operates the switching circuit to control a voltage signal across the output nodes using a first clock signal and a phase shifted second clock signal to reduce output ripple current and enhance converter efficiency using valley current control. The output inductors are wound on a common core in certain examples.

Abstract: An RFID transponder having an analog front end receiver having an attenuator coupled to receive an RF-signal from an antenna and to attenuate the RF-signal, an amplifier having a fixed amplifier gain and being coupled to receive and to amplify the attenuated RF-signal and a control unit coupled to control a gain of the attenuator, wherein the control unit is configured to control the attenuator gain in response to a level of the amplified RF-signal, the control unit is configured to have a plurality of predetermined states causing the attenuator to increase (step-up) or to decrease (step-down), its gain by a predefined step size, wherein the step size of a step-up is equal to or smaller than the step size of a step-down and wherein the control unit is further configured to switch, upon reaching or exceeding a predefined threshold value, from a first to a second state having a smaller step size and causing the attenuator to change the gain such that the slope of the RF signal inverts and to switch, upon reaching the predefined threshold again, to a third state causing the attenuator to change a prefix of the gain.
