Abstract: An inspection system based upon an enclosed conveyance such as a van, capable of road travel, for inspecting objects of inspection that may include persons. The conveyance is characterized by an enclosing body, or skin. A source of penetrating radiation and a spatial modulator for forming the penetrating radiation into a beam, both contained entirely within the body of the enclosed conveyance, irradiate an object with a time-variable scanning profile.

An image is formed of the contents of the object based in part on the scatter signal and the relative motion signal. A detector, which may be separate or part of the scatter detector module, may exhibit sensitivity to decay products of radioactive material.

Abstract: The present invention is directed to a method of notifying a caller of personal event information during the set-up of a call between the caller and a called party. A query is received from a communication network carrying the call from the caller to determine if the caller is a subscriber to a notification service. If the caller is a subscriber, a Notification and Management System (NMS) is queried to determine if the caller has any pending notifications pertaining to personal event information. If the caller has pending notifications, the call is temporarily sent to an announcement system. The pending notifications are played to the caller during call set-up. The communication network is instructed to continue to route the call to the called party.

Users may also interact with the system via a variety of interfaces such as speech, dual tone multi-frequency, and graphical user interface. The system allows user to compose voicemail messages with embedded applets for delivery to multiple recipients. The applets provide the sender with the ability to leverage the voice messaging system so as to take full advantage of all systems and applications of the computer platform upon which the applet is being run. The voice message based applets may be updated dynamically based upon variables such as when the recipient receives the message. The message sender may also configure the system to provide notification and statistics regarding receipt of the message and embedded applets.

Abstract: A quick startup procedure for a modem system utilizes known characteristics of a previously established communication channel to reduce the initialization period associated with subsequent connections over the same channel. In response to the establishment of a call, the modem devices determine whether the quick connect protocol is supported. If so, then the called modem transmits a modified answer tone to the calling modem. The calling modem analyzes the signal received in response to the modified answer tone to determine whether characteristics of the current channel are similar to stored characteristics associated with a previous connection over the same channel. If a channel “match” is found, then the modem devices carry out a quick initialization routine that eliminates, abbreviates, or modifies a number of procedures or protocols that are carried out in conventional modem startup processes.

Abstract: A subscriber-line interface circuit (SLIC) has tip and ring amplifiers connected to the tip and ring lines, respectively, of customer premises equipment (CPE). The SLIC returns the ringing signal (provided to the CPE from a power supply connected to the CPE's ring line), to ground or to battery, through the SLIC's tip amplifier. In one embodiment, the SLIC has three switches: S1 connecting the power supply to the ring line, S2 connecting the ring amp to the ring line, and S3 connecting the tip amp to the tip line. During ringing, S1 and S3 are closed to return the ringing signal to ground through the tip amp, which is preferably driven to saturation during ringing to reduce power consumption. By eliminating the fourth switch that appears in prior-art SLICs (e.g., connecting the tip line to ground), SLICs of the present invention can be smaller and therefore less expensive to implement.

Abstract: An echo canceller circuit for use in an echo canceller system is set forth that provides sensitive double-talk detection. The echo canceller circuit comprises a second digital filter having adaptive tap coefficients to simulate an echo response occurring during the call. The adaptive tap coefficients of the second digital filter are updated over the duration of the call using a Least Mean Squares process having an adaptive gain a. A channel condition detector is used to detect channel conditions during the call. The channel condition detector is responsive to detected channel conditions for changing the adaptive gain a during the call. For example, the channel condition detector may detect the presence of a double-talk condition and set the adaptive gain a to zero. Similarly, the channel condition detector may detect the occurrence of a high background noise condition and set the adaptive gain a to a level less than 1 that is dependent on the detected level of the background noise.

Abstract: An echo canceler includes an adaptive filter that adapts to changes in an echo path, a double-talk detector, and an echo path change detector. The echo path change detector estimates the loss on the echo path, thereby distinguishing true double-talk from apparent double-talk detected by mistake because of a change in the echo path. The adaptive filter continues normal adaptation during the apparent double-talk state when echo path change is also detected. The necessary conditions for detection of echo path change preferably include a small separation between the estimated loss on the echo path and a long-term smoothed value of the estimated loss. The echo path change detector is useful in, for example, the cancellation of line echo in telephone switching systems.

That is, using the image public key easily identifies to whom the public key belongs so use of the wrong public key is less likely.
