TL;DR: In this paper, a user interface with guide lights for a communications device, such as a mobile telephone, is provided to assist a user in the correct and efficient operation of the device having a display, and a keypad which contains a numerical 10-key and other control keys.
Abstract: A user interface with guide lights for a communications device, such as a mobile telephone, is provided to assist a user in the correct and efficient operation of the device having a display, and a keypad which contains a numerical 10-key and other control keys. The user interface includes a means for identifying the appropriate keys on the keypad which correspond to the step or steps required to activate a desired operation to be performed within the device. In the preferred embodiment, identification of the appropriate keys is achieved using a light source which is mounted beneath each translucent key so that when the light source is illuminated, the key associated with that light source will be identified to the user. The intensity of the light sources is variable and may be controlled to provide sufficient contrast to read all keys in low ambient light while highlighting the keys to be pressed for operation of the desired function. In high ambient light, the intensity of the guide lights may be increased for enhanced contrast and visibility. Alternatively, different color light sources may be used, with one color to light all keys for visibility in low ambient light, if needed, and the other color to provide the guide lights.

TL;DR: In this paper, a mail transfer agent adapted for determining the disposition of incoming e-mail from a sender includes a penalty count filter module (20) which functions on the basis of current communication system resource usage, such as the number of concurrent TCP connections being maintained, and penalty counts assigned for cumulative undesirable sender activity such as sending large e mail files.
Abstract: A mail transfer agent adapted for determining the disposition of incoming e-mail from a sender includes a penalty count filter module (20) which functions on the basis of current communication system resource usage, such as the number of concurrent TCP connections being maintained, and penalty counts assigned for cumulative undesirable sender activity such as sending large e-mail files. The penalty count filter module can operate in a selective-rejection state accepting e-mail from senders without a penalty count and randomly accepting other e-mail, and in a random-rejection state rejecting all e-mail from senders with a penalty count and randomly rejecting other e-mail. The rejection rates can be increased or decreased in response to a detected increase or decrease in the usage of system resources.

TL;DR: In this paper, the authors present a method, a computer program product and a device that includes a receiver for receiving a downlink signal transmitted into a cell, which is operable to obtain time, carrier frequency and cell-specific preamble synchronization to the received signal.
Abstract: Disclosed is a method, a computer program product and a device that includes a receiver for receiving a downlink signal transmitted into a cell The receiver is operable to obtain time, carrier frequency and cell-specific preamble synchronization to the received signal and includes a plurality of synchronization units that include a first detector to detect a frame boundary using preamble delay correlation; a second detector to detect the frame boundary with greater precision using a conjugate symmetry property over a region identified by the first detector; a cyclic prefix correlator to resolve symbol boundary repetition; an estimator, using the cyclic prefix, to estimate and correct a fractional carrier frequency offset; an operator to perform a Fast Fourier Transform of an identified preamble symbol and a frequency domain cross-correlator to identify cell-specific preamble sequences and an integer frequency offset in sub-carrier spacing The transmitted signal may be a downlink signal transmitted into the cell from a base station that is compatible with IEEE 80216e (WiMAX)

TL;DR: In this article, a method for checking the access right of a subscriber equipment in a mobile communication system was proposed, where a mobile equipment is registered in a network infrastructure by transmitting the identity of the subscriber from the mobile equipment to the network infrastructure.
Abstract: The invention relates to a method for checking the access right of a subscriber equipment in a mobile communication system. In the method, a mobile equipment is registered in a network infrastructure by transmitting the identity of the subscriber from the mobile equipment to the network infrastructure. In the method, the subscriber equipment identity of the mobile equipment is transmitted (101) to the network infrastructure, the subscriber data of the subscriber is checked (102) in the database of the mobile communication system, and the equipment identity of the subscriber, the equipment identity being stored in the database, is compared (103) to the equipment identity transmitted by the mobile equipment, and if the equipment identities are the same (110) the mobile equipment is allowed to continue operation normally, and if the equipment identities differ (104), the access right of the mobile equipment will be checked in the equipment identity register of the network infrastructure.

TL;DR: In this article, a system and method for displaying map data to a person using either a hand-held or head-worn display is described, where a map image is displayed in a 3D perspective view, allowing the person to easily associate the objects in the map image with the real objects in their field of view.
Abstract: A system and method for displaying map data to a person using either a hand-held or head-worn display is described. In one preferred system, a head-worn display is used. The location of the person and the direction of the person's view is determined. A map image indicated by the location and direction is presented in the display. This map image is displayed in a three-dimensional perspective view, allowing the person to easily associate the objects in the map image with the real objects in the person's field of view. In addition, the user may indicate a desired destination and the three-dimensional perspective view will be changed according to the user's location relative to the desired destination.
