Abstract: An air inlet diffuser 10 is disclosed for attachment relative to an air inlet opening 106 of an electronics enclosure 100. The diffuser 10 extends into the electronics enclosure 100 and provides an increased surface area through which EMI attenuating apertures may be formed. The diffuser 10 also reduces the amount of structure that is disposed within the air inlet opening 106 thereby reducing impedance to airflow through the opening 106 into the enclosure 100. The increased surface are of the diffuser 10 allows for increasing the number of EMI attenuating apertures that may be utilized for a given inlet opening 106. In one embodiment, the total open area of the EMI apertures is greater than the open area of the air inlet opening. In such an embodiment, the EMI apertures provide low impedance to airflow through the diffuser 10 and increased airflow in conjunction with EMI attenuation may be realized.

Abstract: The invention is concerned with an antenna arrangement adapted to a mobile terminal and division of frequency bands between different antennas. The antenna arrangement enables the terminal to operate worldwide in networks applying different frequency bands and technologies, as a so-called multi-band terminal. In the antenna arrangement the frequency bands of the antennas are arranged for each antenna in a way that the bands fill an optimal frequency area, thus accomplishing smaller total volume for the antennas and a good performance.

Abstract: The present invention is a technique for measuring optimum focus position of a lens to include the steps of capturing a digital image in the field of view, digitally compressing the image to provide a compressed file having a file size and providing a focus accuracy parameter derived from the file size of the compressed file. The key point of this invention is the recognition that the compressed file associated with a given image increases monotonically in size as the image is brought into focus. The latter occurs because a focused image has greater information content than an unfocused image. With such a technique, an optimal focus position of a lens can be determined by maximizing a single parameter, the compressed output file size.

Abstract: The present invention relates to a locking arrangement for a cover structure of a portable terminal device of a telecommunication system. The cover structure comprises at least one frame part (14), a cover part (16) connected to the frame part that can be removed from the frame part by the user, and locking elements for attaching the cover part to the frame part. In order that one could achieve a secure attachment and locking for the accumulator cover or accumulator packet of the device that at the same time enables the eliminating of the excessive clearances between the can parts, the locking elements comprise, in the frame part and cover part, slide bars (50, 51) and slide grooves (80) corresponding to each other.

Abstract: A data input method in user terminals having a limited-size keyboard with two different data input methods linked in such a way that toggling between the modes does not require from the user any special action during text input, since the change of mode is automatically performed as a result of keystrokes which are normal when a text is being edited.

Abstract: A system for interfacing a multi-interface card to a non-standard interface is provided. The system includes a detection module that detects an input signal; and a switching module that operationally couples the multi-interface card to an interface based on the input signal. The switching module operationally couples the multi-interface card to a serial interface, a USB interface, a PCMCIA interface or to any non-PCMCIA interface. The system also provides a docking device that is coupled to a computing device, for interfacing a multi-interface card to non-standard interfaces. The docking device includes an interface that receives the multi-interface card; detection logic for detecting the multi-interface card; and a converter that receives signal from the multi-interface card and converts the signals based on an interface that couples the docking device to the computing system.
