Abstract: A controller for an AC-DC converter including a rectifier circuit that converts AC input voltage into DC output voltage uses control logic to control the rectifier circuit according to two or more operating modes. Each operating mode determines a gain of the rectifier circuit.

The change in the feature is detectable in digital images of the lens taken with a mobile electronic device such as a smartphone.

Abstract: A device for non-invasive monitoring and measuring of intraocular pressure (IOP) of a subject includes a flexible lens that fits on the eye and changes curvature in response to a change in curvature of the eye. A microchannel disposed in or on the lens has one or more ends that are open to the atmosphere and an indicator solution is disposed in a portion of the 5 microchannel.

The change in position of the indicator solution in the microchannel is indicative of a change in IOP. The change in position of the indicator solution may be detected in digital images of the lens taken with a camera of a mobile electronic device such 0 as a smartphone or a camera worn by the subject.

Abstract: A method of beamforming by which a signal can be received into an array of channels, each of which is split into a real-part sub-channel and an imaginary part sub-channel. In each sub-channel, optical waves are used to carry the signal via waveguides. Each channel includes a real-part sub-channel where an optical wave is scaled by the real part of a complex number, and an imaginary part sub-channel, where a complementary optical wave is scaled by the complex part of the same complex number. When the complementary optical waves are received at the channel's output, they can be shifted by the phase of the complex number having defined their scaling. By processing a signal with a system operative to perform such method, the application of a different phase to each channel can result in a beamforming of the signal.

Abstract: A control circuit for an isolated power converter includes a first sensing circuit that senses a secondary side output voltage and produces a pulse width modulation (PWM) signal having a duty cycle that is proportional to a value of the secondary side output voltage. The PWM is transferred a cross the converter isolation barrier to the primary side, and a primary side circuit receives the PWM signal and outputs a control signal. A controller determines the value of the secondary side output voltage from the control signal and uses the value to control primary side power switching devices of the isolated power converter to regulate the secondary side output voltage at a selected value.

Abstract: A cloud communication architecture addresses shortcomings of traditional security protocols (e.g., SSL/TLS) in cloud computing, providing security for data-in-transit and authenticity of cloud users (CUs) and cloud service providers (CSPs). The architecture also protects the communication channel against attacks such as man-in-the-middle (MITM) (including eavesdropping, sniffing, identity spoofing, data tampering), sensitive information disclosure, replay, compromised-key, repudiation and session hijacking attacks. The architecture includes a high-performance cloud-focussed security protocol. The protocol efficiently utilizes the strength and speed of features such as symmetric block encryption with Galois/Counter mode (GCM), cryptographic hash, public key cryptography, and ephemeral key-exchange, and provides faster reconnection facility for supporting frequent connectivity and dealing with connection trade-offs. Embodiments have enhanced security against the above-noted attacks, and are superior to TLSv1.

Abstract: A method for generating a propagation and velocity maps for cardiac wavefront propagation including cardiac arrhythmia, sinus rhythm, and paced rhythm. Activation time information is generated in the absence of any time alignment reference, wherein an estimated activation time is a weighted summation of potentially nonlinear and nonorthogonal candidate functions (CFs) selected from a bank of CFs. Time alignments between sequential recordings may be done by including binary level functions among selected CFs. Embodiments are applicable to single catheter mapping and sequential mapping, and are robust as confirmed by the ability to generate propagation maps and conduction velocity in the presence of multiple colliding wavefronts. The propagation and conduction velocity maps may be used for one or more of diagnosing cardiac arrhythmia, localizing cardiac arrhythmia, guiding catheter ablation therapy of cardiac arrhythmia, and guiding cardiac pacing therapy.
