Techniques are described for real-time disparity upsampling for phase detection autofocus (PDAF) in digital imaging systems. For example, an imaging sensor array includes a number of physical PDAF sensors that provide a PDAF resolution that is a small percentage of the resolution of the imaging sensor itself.

For each upsampling location, embodiments can compute local disparity values and local contrast values for each of multiple neighboring physical PDAF sensors. An upsampled disparity value can be computed for the upsampling location by weighting the neighboring local disparity values based at least on the neighboring local contrast values. The upsampled disparity values can yield higher-resolution information for use in PDAF operations.

US11302859B2 Zero-power wake-up sensing circuit in piezoelectric haptic feedback
Piezoelectric elements are attractive for systems in which both sensing and actuating is required because a single element, i.e. the piezoelectric actuator, can be used that act as both a sensor and an actuator. In conventional systems combining both actuating and sensing functionality, active circuitry is required to read the sensor, and that circuitry requires static and/or dynamic current from a few microamps to a few milliamps. In systems where buttons are used a few times a day, this requirement for current leads to a significant amount of wasted power. Accordingly, a wake-up circuit is provided that does not draw power when no force is applied to the piezoelectric actuator but is capable of detecting pressure applied to the piezo actuator, generate a power-up signal to the actuating circuit, and initiate a haptic feedback with low-latency.

US11302839B2 Integrated micro-lens for photovoltaic cell and thermal applications
A design for a micro-lens (i.e., a lens on the scale of micrometers) incorporates existing nanofabrication techniques and can be incorporated into High Concentrating Photovoltaic (HCPV), solar thermal collectors, and traditional flat PV systems. Using the theory of wave optics, the design is able to achieve a high numerical aperture, i.e., it can receive light over a wider range of angles. The design also reduces the distance the focal point shifts as the light source shifts; this eliminates the need for a tracking system in CPV and PV applications. Reducing the lens size also facilitates smaller, lightweight CPV systems, which makes CPV attractive for additional applications. Finally, these concentrators reduce the exchanging area of a typical flat solar thermal system where heat is received, which improves the overall system's efficiency and allows its use also during rigid winter time.

Therefore, off-state current of a thin film transistor can be reduced, leading to suppressing the leakage of electric charge stored in a capacitor, through the thin film transistor. Accordingly, a malfunction of the logic circuit can be prevented. Further, the excessive amount of current which flows in the logic circuit can be reduced through the reduction of off-state current of the thin film transistor, resulting in low power consumption of the logic circuit.

US11301845B2 Cryptoasset custodial system with proof-of-stake blockchain support
Methods and systems for secure storage and retrieval of information, such as private keys, useable to control access to a blockchain, include: receiving, in a cryptoasset custodial system, a request to authorize a staking operation associated with a blockchain, wherein the staking operation is associated with a private key of an asymmetric cryptographic key pair, the private key is usable to control ownership of a cryptoasset recorded in the blockchain, and the private key is securely held in the custodial system; performing, in response to the request, a portion of the proof-of-stake protocol in a hardware security module using logic designed for the protocol, wherein the logic in the hardware security module is configured to authorize the staking operation by digitally signing an associated staking transaction; and sending the digitally signed staking transaction to another computer to effect the staking operation on behalf of the user.
