Abstract: A portable device for detecting a large vessel occlusion in a patient's brain by transmitting a signal into both sides of the brain and receiving the reflections of the transmitted signals to capture a single reflection data point of the characteristics of the blood vessels and brain tissue on both sides of the brain. Using the captured single reflection data point values to perform a comparative analysis between the right and left side of the brain, and based on this analysis, assessing whether the patient is experiencing a large vessel occlusion. If so, the device generates an alert.

Abstract: Error correction for stacked memory is described. In accordance with the described techniques, a system includes a plurality of error correction code engines to detect vulnerabilities in a stacked memory and coordinate at least one vulnerability detected for a portion of the stacked memory to at least one other portion of the stacked memory.

Abstract: Systems and methods for dynamic and automatic data storage scheme switching in a distributed data storage system. A machine learning-based policy for computing probable future content item access patterns based on historical content item access patterns is employed to dynamically and automatically switch the storage of content items (e.g., files, digital data, photos, text, audio, video, streaming content, cloud documents, etc.) between different data storage schemes. The different data storage schemes may have different data storage cost and different data access cost characteristics. For example, the different data storage schemes may encompass different types of data storage devices, different data compression schemes, and/or different data redundancy schemes.

Abstract: A digital audio pass-through device capable of connecting multiple host computing devices is described. The digital audio pass-through device allows computing devices such as personal computers (Mac or PC), tablets, and smart phones to share high quality digital audio data streams with one another via USB connections. The digital audio pass-through device also allows for the aggregation of high quality audio data from multiple computing devices with limited to no latency.

Abstract: A router for a plurality of MIDI transmitters and receivers routes MIDI event data to and from designated ports without a host computer system connected to the router. Since a host computer system is not used, delay times are significantly reduced and many MIDI devices could be coupled to the router without significantly impacting the transmission speeds of the MIDI data. While the router works without a host connected to the router, the router could still function while a host computer is connected, which is useful when a host computer is used to send MIDI event data or record MIDI event data.

Abstract: The instant invention provides a geothermal cooling system for cooling semiconductor PV panels operating in either concentrating or non-concentrating mode, which comprises heat sink mounted onto the underside of the silicon PV panel, a subterranean-level condenser, and other necessary equipment. Different embodiments of the geothermal cooling system are also provided in this invention.

Abstract: A cable for establishing electronic communication between a first device and a second device is described. One end of the cable comprises a standard USB device connector that has four electrical contacts; two for power (VBUS, GND) and two for differential data signals (D+ and D?). The other end of the cable comprises a proprietary device connector having at least four corresponding electrical contacts and at least one additional electrical contact. The cable also has inline circuitry configured to control the power direction between the ends of the cable based on a characteristic of a signal originating from an electrical contact of the USB device connector. The devices and methods described herein enables reverse direction power across a standard 4 wire USB device receptacle in a non standard way while autonomously providing standard USB data connectivity.
