Abstract: A wireless device includes one or more antennas coupled to a transmit (TX) chain. The TX chain is configured to generate output RF signals using baseband signals. The TX chain includes a TX power controller configured to classify a packet of the output RF signals into a priority category of a plurality of priority categories based on priority information within the packet. The TX power controller is further to determine a time average specific absorption rate (TAS) energy budget of the wireless device.

Transmission power for transmitting the packet is determined based on the priority category and the TAS energy budget. The packet is encoded for transmission via the one or more antennas using the determined transmission power.

Abstract: A propeller control system of an air mobility is configured to insert a movable part forming a propeller into a fixed part in a situation where the air mobility is stored and crashes, thereby reducing an entire length of the propeller. As a result, an entire size of the air mobility is reduced when the air mobility is stored, which may prevent secondary accidents caused by fragments generated by contact of the rotated propeller with the ground in the situation where the air mobility crashes.

Abstract: In some embodiments, a computer system chassis comprises a chassis side having an antenna portion and a fan portion. The antenna portion is located closer to an antenna located on an external surface of the chassis side than the fan portion. The antenna and fan portions comprise ventilation holes that provide for the venting of heated air from the chassis interior to the surrounding environment. In some embodiments, the ventilation holes in the antenna portion are thicker than the ventilation holes in the fan portion. The thicker ventilation holes provide an adequate level of EMI shielding for the antenna from platform noise generated by components (CPUs, GPUs, memories, etc.) located in the chassis interior. In other embodiments, the antenna portion comprises alternating positive and negative cross pattern ventilation holes and provides an adequate level of EMI shielding with the antenna portion ventilation holes having the same thickness as the fan portion ventilation holes.

Abstract: A vehicle detection system warns snowmobilers of other approaching vehicles with potential risk of collision. To better prevent accidents, the system calculates collision risks and warns the rider based on level of risk. When riding in groups, a member can press a stop request button to ask the group to slow down. When a member exits the group, everyone in the group will receive a message, alerts or indication with the update. The vehicle detection system utilizes Bluetooth® low energy (BLE), LoRaWAN® technologies and/or global positioning system technologies and is designed to detect other devices in the region and use acquired information to calculate proximity and risk of collision.
