Abstract: Example control methods, apparatuses, and vehicles are described. One example method includes obtaining first configuration information, where the first configuration information is information obtained based on an operation of enabling or disabling a first function of a vehicle by a user. A working status of a first controller is controlled based on the first configuration information, where the working status includes a first working state and a second working state. The first controller enables the first function in the first working state and disables the first function in the second working state. Power consumption of the vehicle when the first controller is in the second working state is relatively lower than power consumption of the vehicle when the first controller is in the first working state.

Abstract: An electronic device includes a case and a shoulder button module. The shoulder button module is movably disposed in the case and includes a keycap, a push switch, and a touch sensing assembly. The keycap is exposed from the case. The push switch is located in the case and disposed under the keycap. When the keycap is pushed downward, the push switch is triggered. The touch sensing assembly is disposed in the keycap so as to sense an input command touched on the keycap.

Abstract: A thermal dissipation device for a handheld electronic device is provided. The thermal dissipation device includes a thermoelectric cooling chip, a temperature sensor, a humidity sensor, and a processing unit. The thermoelectric cooling chip has a cold surface and a hot surface. The cold surface is attached on a heating surface of the handheld electronic device by means of a heat conduction structure, and has a cold surface temperature. The temperature sensor and the humidity sensor are disposed in an area adjacent to the thermoelectric cooling chip for generating an environmental temperature and an environmental humidity respectively. The processing unit is configured to calculate a dew point temperature based on the environmental temperature and the environmental humidity; and determine whether to stop the thermoelectric cooling chip or not based on the cold surface temperature, the dew point temperature, and a heating surface temperature of the handheld electronic device.

Abstract: The invention provides polymers of Formulas I-III, such as polyesters and unsaturated polyesters, and crosslinked and copolymerized polymers thereof. The invention also provides methods to catalytically ring-open five-membered rings such lactones, lactams, and thiolactones, as via ring-opening polymerization. The polymerization products are recyclable and can be depolymerized back to their monomer form via thermolysis and acid or base catalysis.
