Abstract: Technologies for temperature gain control on radar units are described. A method includes determining a first value for an internal operating temperature corresponding to a steady-state of a radar unit. The method further includes causing the radar unit to operate in a first mode that heats the radar unit. The method further includes obtaining a second value for the internal operating temperature at a first time in the first mode and determining a third value indicating a measurement bias associated with the radar unit. The method further includes determining a fourth value using the second value and the third value. The fourth value indicates an updated internal operating temperature of the radar unit. The method further includes determining that the fourth value satisfies a threshold temperature condition corresponding to the first value. The method further includes causing the radar unit to stop operating in the first mode.

Abstract: A food delivery enclosure for delivering groceries includes a low insulation zone and a high insulation zone. The low insulation zone includes energy packs, such as chill packs or hot packs and food items suitable for contact with the energy packs. The high insulation zone is above the low insulation zone and includes food items that are not suitable for contact with the energy packs.

Abstract: In one embodiment, a packaging material can be used to form a package such as a bag or a box. The material has a substrate and a plurality of insulation members, each having a body that is adhered to a surface of the substrate and each having a plurality of expandable microspheres. The bodies are a pattern such that the bodies are spaced apart from one another by gaps. The expandable microspheres expand in response to the application of energy such that the insulation members to expand towards one another to at least partially fill in the gaps. In another embodiment, the material has microspheres that are activated such that the insulation members include extensions that extend from their respective bodies towards one another to fill in the gaps.
