Aeromarine M-1. The Aeromarine M-1 was a two-seat training biplane ordered by the US Army's  Aviation Section, U.S. Signal Corps (USAAS) in 1917 and built by the Aeromarine Plane and Motor Company of Keyport, New Jersey.

Design and development
Originally known as Aeromarine Training Tractor, Aeromarine's chief designer, Charles F. Willard, designed a two place trainer in both land-plane and seaplane configuration. The land plane was designated the Aeromarine M-1 and was produced to US Army Specification No.1001. The seaplane version was later called the Aeromarine 39 and sold to the United States Navy (USN). Both aircraft shared much in common, aside from the undercarriage, the primary difference was that the M-1's wingspan was shorter than the Aeromarine 39.

Operational history 
Six aircraft were produced and assigned serial numbers 265/270. During Army testing, the aircraft proved to be unsuitable for a training. "Preliminary tests showed that the M1 was unstable in anything but level flight, and most spent the war years packed in their crates."

In 1920, there was a proposal to re-engine these aircraft with the Aeromarine 100hp motor

Relative thermal index. The Relative thermal index (RTI) is a characteristic parameter related to the ability of plastic materials to resist thermal degradation.

The RTI is part of the longterm thermal aging program (LTTA) described in the UL 746B standard from UL.

During the process of the UL 746B program, the degradation in hot air of certain properties of the material like dielectric and mechanic strength, is investigated with regards to thermal-aging. For a full study, the candidate material (B) is aged together with a reference material A (control) with already known RTI value in the same ovens. The RTI is the rounded temperature in degrees C, at which the properties of B have decreased to 50 percent of their initial value in about the same amount of time (correlation time) than it takes for A at its own RTI value. A maximum correlation time of 60.000 hours is considered acceptable for many electrical applications, however it may also become as low as 5.000 hours according to UL 746B. If a material has not been investigated (yet), the RTI shown is based on the generic class (polymer type) of the material.

Though the RTI is an index, it is given in Celsius units. The UL 746B standard distinguishes between three sub-categories of the RTI:
Electrical RTI which relates to electrical insulating performance.
Mechanical impact RTI which relates to mechanical performance with impact
Mechanical strength RTI which relates to mechanical performance without impact
There is also the RTI Elongation (by means of Elongation at break) for films and other nonrigid materials.

DIGI Group. DIGI (Teraoka/DIGI Group) is a global corporation with offices in Japan, Europe and North America. Founded in 1925, it supplies weighing and packaging equipment for trade, industries, and logistics. Its products are widely used in the manufacturing, retail, and consumer fields. The company occupies 30% of the Russian market of weighing scales.

Although the company dates back to 1925, its activity dates back to 1910, when industrialist Teraoka Toyonaru created the Japan Calculation Machinery Manufacturing Co, which was focused on innovative technologies and supporting inventions. It produced precision instruments for industries and consumers. At the time of its inception, Teraoka had already developed weight scales capable of functioning under different temperature environments, which had been patented in Japan, the United States, the United Kingdom, Germany and France. Establishing itself firmly in its market,  Teraoka Takeharu, son of Toyonaru, started the Teraoka Research Center (Teraoka Seiko Co., Ltd.), which would eventually form part of Teraoka/DIGI Group. The corporation presently operates five R&D centres and five production sites across Europe and Asia, as well as its own line of strain gauges.

Kagome metal. In solid-state physics, the kagome metal or kagome magnet is a type of ferromagnetic quantum material.   The atomic lattice in a kagome magnet has layered overlapping triangles and large hexagonal voids, akin to the kagome pattern in traditional Japanese basket-weaving.  This geometry induces a flat electronic band structure with Dirac crossings, in which the low-energy electron dynamics correlate strongly.      

Electrons in a kagome metal experience a "three-dimensional cousin of the quantum Hall effect": magnetic effects require electrons to flow around the kagome triangles, akin to superconductivity.  This phenomenon occurs in many materials at low temperatures and high external field, but, unlike superconductivity, materials are known in which the effect remains under standard conditions.     

The first room-temperature, vanishing-external-field kagome magnet discovered was the intermetallic , as shown in 2011.  Many others have since been found.  Kagome magnets occur in a variety of crystal and magnetic structures, generally featuring a 3d-transition-metal kagome lattice with in-plane period ~5.5 Å.  Examples include antiferromagnet , paramagnet , ferrimagnet , hard ferromagnet (and Weyl semimetal) , and soft ferromagnet .  Until 2019, all known kagome materials contained the heavy element tin, which has a strong spin–orbit coupling, but potential kagome materials under study () included magnetically doped Weyl-semimetal , and the class  (A = Cs, Rb, K).  Although most research on kagome magnets has been performed on Fe3Sn2, it has since been discovered that  in fact exhibits a structure much closer to the ideal kagome lattice.    

A kagome lattice harbors massive Dirac fermions, Berry curvature, band gaps, and spin–orbit activity, all of which are conducive to the Hall Effect and zero-energy-loss electric currents. These behaviors are promising for the development of technologies in quantum computing, spin superconductors, and low power electronics.   in particular exhibits numerous exotic properties, including superconductivity, topological states, and more.  Magnetic skyrmionic bubbles have been found in Kagome metals over a wide temperature range. For example, they were observed in  at ~200-600 K using LTEM but with high critical field ~0.8 T.

Bye Aerospace Sun Flyer. The Bye Aerospace Sun Flyer (also previously known as the Aero Electric Aircraft Corporation Sun Flyer) is an electric aircraft that was developed from the PC-Aero Elektra One by Bye Aerospace's Aero Electric Aircraft Corporation division of Denver, Colorado, United States, introduced in 2015. The company had a license agreement and engineering contract for the design with Calin Gologan, the Elektra One's designer.

Design and development
The aircraft features composite construction, a cantilever low-wing, a single-seat, enclosed cockpit under a bubble canopy, fixed tricycle landing gear with wheel pants and a single electric motor in tractor configuration.

The Sun Flyer differed from the PC-Aero Elektra One by incorporating new landing gear, propeller and instruments. It provided a prototype for a proposed two-seater that was to have four Panasonic lithium-ion batteries, along with solar panels installed on the wings, horizontal tail and on the fuselage behind the canopy. This two-seater was intended to be certified for day and night Visual Flight Rules. The proposed two-seat version of the Sun Flyer eventually led to a new design, the Bye Aerospace Sun Flyer 2 instead.

The Spartan College of Aeronautics and Technology had reserved the first 20 two-seat models that were to be produced.

Mitek Systems. Mitek Systems, Inc is a software company that specializes in digital identity verification and mobile image processing using artificial intelligence. The company's software is used for depositing checks and opening bank accounts via mobile devices. It also verifies identity documents such as passports, ID cards, and driver's licenses by analyzing a selfie of an individual holding their ID, comparing their face to the photo on the document.

History 
The company was founded in 1986, and is headquartered in San Diego, California.

In 2011, it was announced that Mitek intended to expand into mobile imaging software for the health care and insurance industries, in addition to mobile banking.

In 2014, USAA and Mitek Systems, Inc. settled a -year-old dispute over the invention of the technology used for mobile check deposits, with both companies' patents remaining intact and neither side paying the other.

On May 26, 2015, the company acquired IDchecker, a provider of cloud-based identity document verification and facial recognition products.

On October 16, 2017, the company acquired Icar Vision Systems, a Spanish company specializing in customer identity verification.

In August 2023, Mitek revealed that it had received a delisting notice from the Nasdaq Stock Market due to its failure to file quarterly with the U.S. Securities and Exchange Commission on time. The company presented a new plan for compliance to Nasdaq.

Controversies 
In 2012, Mitek sued the USAA (United Services Automobile Association) in Delaware on several counts relating to five Mitek patents relating to mobile image capture and breaching licensing agreements. The lawsuit was settled in September 2014 with no payments and both parties acknowledging that each has distinct patent rights.

revived in 2022 by a U.S. appeals judge who claimed the former judge's logic was "not sufficiently complete" and he should reexamine the case.

HyreCar, an app that allows car owners to rent out their vehicles for drivers, uses Mitek technology to verify users' identities. It requires its customers to sign an arbitration agreement so they can't sue the company for violating an Illinois biometric privacy law.

HyreCar customer Joshua Johnson claimed that Mitek violated the Illinois biometric law by collecting and storing driver information. Mitek sought to take the case to arbitration to avoid being sued in court, but in December 2022, the 7th U.S. Circuit Court of Appeals upheld a previous ruling that Mitek is not included in HyreCar's arbitration cause and can be sued in court.
