Abstract: A system for analyzing the concentration of a first component in a sample fluid is described. The system provides a mixture of sample fluid and control fluid to a fluid concentration measuring apparatus in a controlled ratio. The system stores flow change model, representing the variation in time of the flow of the sample fluid through the system between a valving and the fluid concentration measuring apparatus in response to a variation of the controlled rate by the valving. The system estimates the concentration of the first component in the sample fluid based at least in part on the controlled ratio, and the flow change model.

Abstract: A contact lens and a method for treating an eye with myopia is described. The contact lens includes an inner optic zone and an outer optic zone. The outer optic zone includes at least a portion with a first power, selected to correct distance vision. The inner optic zone has a relatively more positive power (and add power).

Abstract: A wearable device utilizing flexible electronics is disclosed. The wearable device may comprise a flexible matrix material and may include sensors for measuring biometric measurements of an individual, an accelerometer for measuring an acceleration of a body part to which the wearable device is attached, a wireless transmitter, a flexible power source, and a microcontroller. During an activity, the microcontroller may receive signals from the sensors including the biometric measurements, and signals from the accelerometer including acceleration and force measurements associated with the individual. The microcontroller may convert the signals into digital signals and transmit the signals to a computing device for analysis. The computing device may analyze the digital signals to determine a performance metric for the individual. The performance metric may be compared to baseline data for the individual to determine a fatigue level, injury risk, or an adjustment to be made by the individual during the activity.

Abstract: A rugged, ergonomic integrated telecommunications handset includes an electronic controller that interoperates and controls the universal remote control (URC), which connects to multiple radios simultaneously. The controller downloads options which are implemented by the controller. The handset has an ability to vibrate in a silent mode, and has a memory capacity, as well as GPS capacity. Ergonomically, the handset has a pair of side arrays of protruding ribs, which enhance gripping, preventing the handset from falling out of the user's hands, even if the user has gloves on in inclement weather conditions in the field. While compatible with the latest radio system software defined dual net and dual channel radio equipment, the handset is also backward compatible with single radios or with two or more separate radios, and may communicate using Bluetooth.

The one or more thermal emitters are configured to generate heat to deice the one or more external structures. The one or more thermal emitters are configured to receive electrical power from one or more of an auxiliary power unit of the aircraft, a power distribution system of the aircraft, one or more engines of the aircraft, or an external power cart that is separate and distinct from the aircraft.

Abstract: A generative interactive video computer-implemented method and system applies trained computer-implemented neural networks to generate a sequence of images, which may comprise a video, and which contains identified objects, and then delivers the sequence of images to a user. The sequence of images may be further generated in accordance with an inference of a preference from user behavioral information. The identified objects may be provided to the system in the form of natural language and/or images. The system then generates and delivers to users natural language-based responses to user requests for information with respect to the identified objects, including attributes that are associated with the identified objects. Users may direct the system to generate video-based virtual environments that include representations of the identified objects.

Abstract: Provided is a food composition which include a myceliated high-protein food product and methods to make such compositions, which are mixtures of myceliated high-protein food products and other edible materials. A food composition includes dairy alternative products, ready to mix beverages and beverage bases; extruded and extruded/puffed products; sheeted baked goods; meat analogs and extenders; baked goods and baking mixes; granola; and soups/soup bases. Food compositions also include texturized plant protein which can be used for making meat-structured plant protein meat analog or meat extender products. The food compositions have reduced undesirable flavors and reduced undesirable aromas due to use of myceliated high-protein food products as compared to use of similar high-protein material that is not myceliated.

The stand includes a hub and multiple legs pivotable with respect to the hub. The legs are pivotable outward from stowed positions to preset operational pivoted positions. The user can select a preset operational pivoted position in which outward pivoting of a leg will stop based on moving an actuator between preset locations.

Abstract: This application relates to a building energy analysis and management system for measurement and verification of building performance. The system can analyze, optimize, manage, maintain, trouble shoot, and/or modify building systems, such as HVAC systems, in connection with the building energy usage. Measurements may be gathered for one or more HVAC units coupled to pressure independent valves, and sent to one or more Surge Panels that pass data to remote analysis servers, which can receive other system or external data. The analysis servers compare measurements to predicted values and can standardize the predicted values to account for external conditions. The comparison can result in difference values used to generate probable causes and optimization recommendations. The system outputs reports or other data display using a graphical user interface that can be adjusted for an anticipated user.

Abstract: A virtual mailbox is established for a first user based on a virtual mailbox definition specified by the first user. A message directed to the first user is received from a first device associated with a second user. A location within a real-world environment of the first user corresponding to the virtual mailbox is identified. A marker associated with the virtual mailbox is detected within the real-world environment of the first user. Based on detecting the marker, the second device presents the message overlaid on the real-world environment at the location corresponding to the virtual mailbox.

Abstract: A retractable vehicle step is attachable to a vehicle or truck. The vehicle step facilitates access to a cargo hold, interior, or roof of the vehicle. Advantageously, the vehicle step may provide clearance space relative to a tailgate of the vehicle by displacing a stepping member of the vehicle step in a generally lateral direction. The vehicle step desirably has a covered and protected biasing mechanism for transitioning between retracted and extended positions of the stepping member. Advantageously, the vehicle step may be pulled out from under the vehicle by the foot of a user. Another advantage is that the vehicle step is readily attachable to the vehicle using already existing connection members, thereby generally eliminating or mitigating the need for customized retrofitting and avoiding undesirable installation cost and time. Finally, the vehicle step may be configured into at least two different arrangements for attachment to a vehicle utilizing the same components.
