A digital license plate supporting both access and analysis of vehicle relevant information is disclosed. The digital license plate includes sensors that provide status data to a processor in the digital license plate. A power path control module can initiate power state changes and adjust power depending on system state as determined by at least one the multiple sensors. In some embodiments a temperature control module is connected to a temperature sensor and configured to modify heat relevant display parameters as critical temperatures are approached.

Digital license plate system

Vehicle mounted exterior displays and digital license plates able to operate over a wide temperature range are disclosed. In one embodiment, heat relevant display parameters can be modified as critical low temperatures are approached. If decreasing temperature is determined to be likely to interfere with display switching operation, legally required information is displayed and potentially interfering content is eliminated.

Thermal control system for a digital license plate

A digital license plate system having various power and communication modes to improve performance and increase expected battery life is disclosed. In one embodiment, a response to a sensor triggered plate event requires determination of whether a vehicle is running, parked or in-motion. This determination involves waking the processor, establishing wireless connectivity, and determining if the vehicle is in motion based on local sensor data.

Power and communication modes for digital license plate

Digital license plates having a range of physical and digital antitheft features are disclosed. Disengagement of the digital license plate from the vehicle triggers at least one of a wireless theft communication signal and the internal theft status indicator. Input of security credentials can prevent triggering the internal theft status indicator and disablement of the digital license plate.

Digital license plate system with antitheft system

Various embodiments are directed to systems and techniques for reducing power consumption in a mobile computing device. In one or more embodiments, a mobile computing device may be arranged to determine a user environment based on detected antenna impedance or detected current. After the user environment is determined, the mobile computing device may confirm that total radiation power (TRP) for the mobile computing device at an initial conducted power level exceeds the minimum TRP threshold required by the network carrier to receive acceptable quality of service (QoS). Based on the excess TRP for the particular user environment, the mobile computing device may determine a reduced conducted power level to be input to an antenna system. Accordingly, significant power savings may be achieved. To save additional power, the mobile computing device may automatically adjust and/or improve antenna impedance matching based on user environment allowing a further reduction in conducted power.

Techniques to reduce radio frequency noise

Various embodiments are directed to antenna designs that may improve the performance of a mobile computing device. Some embodiments are directed to a mobile computing device assembly comprising accessory incorporating a supplemental antenna designed to be adjacent to at least one internal antenna of a mobile computing device when the accessory is attached to the mobile computing device. The supplemental antenna and the internal antenna may cooperatively form an antenna system for the mobile computing device resulting in improved performance. In various implementations, the use of the supplemental antenna in conjunction with the internal antenna may enhance antenna performance and/or increase antenna efficiency. Other embodiments are described and claimed.

Antenna design for an attached accessory

Various embodiments are directed to high isolation antenna design for reducing frequency coexistence interference. In one embodiment, a computing device may comprise a printed circuit board including a first internal antenna and a second internal antenna operating in a common frequency band. At least one of the first internal antenna and the second internal antenna may comprise a balanced antenna coupled to an unbalancing element to suppress surface current on the printed circuit board and reduce frequency coexistence interference between the first internal antenna and the second internal antenna. Other embodiments are described and claimed.
