Antenna devices are provided comprising antenna structures encapsulated or molded into plastic covers of computing devices to enable wireless communication. For example, one or more antenna structures can be encasulated within, or molded into, a plastic display cover of a portable laptop computer. Embedded antenna designs can include various antenna types that are built using one or more wires or thin metallic strips encapsulated into plastic device covers. Insert/injection molding methods can be used to encapsulate antenna structures in plastic device covers during fabrication of the plastic device covers.

A roll over detector for a vehicle is disclosed, which includes a roll over phenomenon detecting circuit that detects a roll over phenomenon of the vehicle based on a relationship between at least a type of physical quantity representative of a roll state of the vehicle and a predetermined threshold; a reacting roll phenomenon detecting circuit that detects a reacting roll phenomenon of the vehicle based on a predetermined criterion, which reacting roll phenomenon occurs in reaction to the roll phenomenon in an opposite direction; and a threshold changing circuit that changes the predetermined threshold from a first threshold to a second threshold so that the roll over phenomenon becomes difficult to be detected by the roll over phenomenon detecting circuit if the reacting roll phenomenon is detected by the reacting roll phenomenon detecting circuit.

Wireless noise is detected within a time period specifically held after a data packet is wirelessly communicated, where no data is purposefully wirelessly communicated during this time period. The time period may be an inter-frame space (IFS) period within which no data is to be wirelessly communicated, and that is a period waited for prior to accessing a wireless medium over which data is wirelessly communicated. One or more actions are performed to counteract the noise. The frequency at which a liquid crystal display is being driven may be decreased so that harmonics caused thereby that caused the noise are no longer within the wireless communication frequency range. An opposite-in-phase version of the noise may also or alternatively be combined with a signal when data is subsequently wirelessly received. The signal includes a data component and a noise component, the opposite-in-phase version of the noise canceling out the noise component.

Electronic device with antenna, antenna structure, and a method for adjusting antenna of electronic device is disclosed. To achieve the above objects, the present invention is an electronic device such as a notebook PC or cellular phone, comprising: a device body, a radiation element for performing reception and/or radiation of electromagnetic wave as an antenna to be equipped with the device body; and a dielectric member placed close to or in contact with the radiation element within the device body, the dielectric member being movable from the outside of the device body to shift the resonance frequency of the antenna. According to the present invention, it is possible, for an electronic device such as a notebook PC having a wireless communication function, to compensate the deviations of resonance frequency of antennas caused by errors in mounting of the antennas for individual devices, the difference in the dimension of structures or the like, to match the resonance frequency to the specified central frequency, for example.
