Abstract: An antenna arrangement includes an antenna reflector (10), a transceiver element (11) and a signal detection unit (12) having a signal converter (121-122) and a computing unit (123) for generating in response to incoming signals control signals for controlling the alignment of the antenna reflector (10) with a target object. The signal converter (121-122) is adapted to reduce its bandwidth automatically and incrementally from a requisite maximum frequency range to a narrow band frequency range. Changes in the direction of the antenna reflector are detected through the medium of a movement detection unit (13) that includes 3d-sensors (131, 132, 133). Mechanical control of the alignment direction of the antenna reflector (10) is effected with the aid of a drive unit (15).

Abstract: A method of providing Internet hosting and access is described. A database is used to store hosting and access descriptors. The hosting and access descriptors describe the configuration of Internet services such as HTTP, SMTP, POP3, IMAP4, and FTP for a hosted site. When a client over the Internet, or other network, requests a service from the hosted domain, the DNS system is interfaced to the database to select a computer to use to support the requested access. The database can also be used to store load information about the computers available for providing Internet hosting and access. Once the DNS system selects a computer and returns the IP address of the computer to the client, the subsequent communications are between the client and the selected computer directly. The selected computer can access the database to retrieve configuration information to respond to service requests from clients.

Abstract: A secure and distributed time service is discussed for use in a network. In particular, the invention relates to Fibre Channel networks and the secure distribution of time service using a push model. In order to distribute time on a push model, one entity assumes responsibility for time in the network. Other entities in the network receive periodic time updates and check the validity of their own time by gauging the elapsed time since the previous time update. The time service is secured using by applying a unique combination of encryption techniques.

Abstract: A photocopier includes a toner bottle that discharges toner from an opening by a rotation, a motor that rotates said toner bottle and a contacting section provided at a position through which a protrusion of the toner bottle passes when the protrusion comes down by the rotation of the toner bottle. When the weight of the toner bottle is more than or equal to a predetermined value, the contacting section descends by the weight of the toner bottle when the protrusion passes through the contacting section, and the contacting section ascend when the protrusion passes away from the contacting section. When the weight of the toner bottle is less than a predetermined value, the contacting section doesn't descend by the weight of the toner bottle.

Abstract: In an internet facsimile apparatus, a mail header receiving section receives a list n-th mail header portion of e-mail. Next, a header analyzing section analyzes the mail header portion and checks whether or not the e-mail is fragments of the e-mail obtained by dividing the e-mail. A table generating section registers the fragments in processing into a table. Thereafter, the fetching determination section checks whether or not the all fragments having the same ID are prepared. If all fragments are prepared, a data receiving section reads the fragments from a mail server sequentially from the first. Text codes of attached files included in the fragments are binary converted sequentially so as to be stored in a buffer section. A printing determination section instructs a print processing section to execute printing when there is image data corresponding to one page of an original in the buffer. This makes it possible to receive a division mail at low cost in the internet facsimile apparatus.

Abstract: A system provides the ability to collect and analyze data generated by a global positioning system to assist in monitoring and supervising a user of a vehicle. The system includes a GPS unit incorporated into a vehicle for periodically generating and recording information with regard to the position and velocity of the vehicle. The recorded information is periodically transferred to a remotely located computer via a wireless communications system, within which a grouping program is implemented. The grouping program is used to identify periods where the vehicle is in a stationary mode and periods where the vehicle is in a moving mode traveling from one location to another, based on the information provided by the GPS unit. The system generates a summary in map or report format. The results of the grouping program may be presented on map images representing the area within which the vehicle traveled. Symbols are drawn onto the map images corresponding to the locations of the stationary segments.

Abstract: A method for aligning an antenna polarization axes of a dual polarized end-user terminal having an antenna. The antenna is aligned with a satellite in relation to azimuth and elevation. The end-user terminal is configured in an alignment mode to produce a first output corresponding to a first component of a received signal parallel to a first polarization axis of the antenna and a second output corresponding to a second component of the received signal parallel to a second polarization axis of the antenna. The first polarization axis is orthogonal to the second polarization axis. The method includes the steps of: receiving a linearly polarized signal; autocorrelating the first output and the second output to produce a measurement of autocorrelation; and adjusting the antenna polarization axes to minimize the measurement of autocorrelation.

Abstract: Demodulation of CPM-modulated information symbols which are demodulated after being transmitted through an AWGN channel, using only partial whitened matched filtering, whereby finite pulses are produced which, however, are still accompanied by interferences in the form of remaining colored noise which can be approximately converted into white noise by a successive additional whitening filter so that the noise power will be minimized. For correcting the accompanying symbol interferences, a sequence estimation with reduced number of states follows.
