Abstract: A receiver circuit includes a rectifier operable in full-, half-synchronous and asynchronous modes. A measurement circuit, with method, provides for real-time power measurement within the rectifier. The measurements are made based on the average output current from the rectifier delivered to the load and measurements sampled over time of the instantaneous voltage at each input/output node of the rectifier. Equivalent resistance in the rectifier is determined from the measurements and power dissipation calculated from the determined equivalent resistance and the average output current. The instantaneous voltages are synchronously captured through high-voltage AC coupling in order to detect the voltage drop across each element of the rectifier. The sensed voltages are amplified in the low voltage domain and converted by a high-speed analog-to-digital converter in order to produce data useful in computing equivalent resistance values. From these values, power dissipation within the rectifier is calculated and real-time equivalent resistance is available.

Abstract: A bridge rectifier is controlled by control circuitry to act a “regtifier” which both regulates and rectifies without the use of a traditional voltage regulator. To accomplish this, the gate voltages of transistors of the bridge that are on during a given phase may be modulated to dissipate excess power. Gate voltages of transistors of the bridge that are off during the given phase may alternatively or additionally be modulated to dissipate excess power. The regtifier may act as two half-bridges that each power a different voltage converter, with those voltage converters powering a battery. The voltage converters may be switched capacitor voltage converters that switch synchronously with switching of the two half-bridges as they perform rectification.

Abstract: A method of making a light sensor module includes connecting a light sensing circuit to an interconnect on a substrate, and forming a cap. The cap is formed by producing a cap substrate from material opaque to light to have an opening formed therein, placing the cap substrate top-face down, dispensing a light transmissible material into the opening, compressing the light transmissible material using a hot tool to thereby cause the light transmissible material to fully flow into the opening to form at a light transmissible aperture, and placing the cap substrate into a curing environment. A bonding material is dispensed onto the substrate. The cap is picked up and placed onto the substrate positioned such that the light transmissible aperture is aligned with the light sensing circuit, with the bonding material bonding the cap to the substrate to thereby form the light sensor module.

Abstract: Disclosed herein is a strain gauge including a substrate, with a first Wheatstone bridge arrangement of resistors disposed on a first surface of the substrate, and a second Wheatstone bridge arrangement of resistors disposed remotely from the first Wheatstone bridge arrangement of resistors. The resistors of the first Wheatstone bridge arrangement are equal in resistance to one another, while the resistors of the second Wheatstone bridge arrangement are unequal in resistance to one another and unequal to those of the first Wheatstone bridge arrangement. The first Wheatstone bridge arrangement of resistors are electrically connected in parallel with the second Wheatstone bridge arrangement of resistors such that each resistor of the first Wheatstone bridge arrangement is electrically connected in parallel with a different resistor of the second Wheatstone bridge arrangement.
