According to a new patent application, Microsoft appears to be
working on power transmission improvements for next-generation
hybrids, 2-in-1s such as the Surface Laptop and Book lineup. In
the same patent application, which was published earlier this
week, Microsoft also revealed its plan to improve the
repairability score of the products.
In the filing, Microsoft notes that the components of the
devices can be replaced with a different housing material from
the original housing material to “increase repairability and/or
customization of the electronic device”.
“The replacement housing component may have different housing
material from the original housing material. For example, an
electronic device with a dented aluminium backplate of the
first housing could be repaired by replacing a portion of the
first housing,” Microsoft noted.
If you replace the portion of the first housing with a
different material, the signal strength of wireless adapters
such as the Wi-Fi will change.
“It should be understood that references in the present
disclosure to replacement, repairs, or modifications to the
housing can refer to a portion of the housing, a layer of the
housing, the entire housing, or any instance where the housing
material in the transmission path changes,” Microsoft writes.
To improve the repairability score and Wi-Fi performance, the
patent from the company has proposed the following solution:
A method of controlling wireless communication performance
in an electronic device includes accessing data containing
material properties relating to a plurality of materials,
transmitting a first test signal on a first transmission
channel with a first antenna at a first location in the
electronic device, receiving the first test signal on the first
transmission channel with a second antenna at a second location
in the electronic device, determining a housing material of the
electronic device based on a measured attenuation of the first
test signal received by the second antenna based upon the data
containing transmission properties relating to a plurality of
materials, and adjusting a transmission power of one of the
first antenna and the second antenna based upon the material
properties of the housing material.
