Abstract: An apparatus, system, and method for an eye-tracking optical verification tester are described herein. In some aspects, a heating element such as a Peltier or Thermoelectric Cooler “TEC” includes a see-through void and may be used to control a temperature of an eye-tracking optical element. An environmental enclosure that is configured to assist in simulation of an environmental condition may hold the eye-tracking optical element. The eye-tracking optical element is to receive reflected light from an eye-tracking target and direct the reflected light to an eye-tracking camera.

Abstract: An interface device configured to interface with one or more aircraft avionics data systems and an antenna. The interface device includes a radio and at least one computing device that are housed inside an enclosure. The radio is connected to the antenna. The radio is configured to transmit outgoing messages and to receive incoming messages via the antenna. The at least one computing device is configured to send the outgoing messages to the radio for transmission by the radio via the antenna and to receive the incoming messages from the radio. The radio may be a very high frequency (“VHF”) transceiver.

Abstract: Apparatus and associated methods relate to a cinch for securing a train of nested shopping carts, the cinch having a non-abrasive cart-handle coupler for securely attaching the cinch to a shopping-cart handle of a front and/or rear cart of the train. In an illustrative example, the non-abrasive cart-handle coupler may include a soft loop of braid configured to latchedly circumscribe the shopping-cart handle. In an exemplary embodiment, the non-abrasive cart-handle coupler may include a latching hook having a non-abrasive handle-engagement surface. In some embodiments, the cinch may secure both a front and a rear cart of the train of nested shopping carts. In some embodiments, a ratcheting member may be used to tighten the cinch that secures the train of nested carts. When tightened, the train of carts may bow upwardly, elevating wheels attached to carts at both the front and rear ends of the train.
