Abstract: A Distributed Mode Loudspeaker (DML) assembly which includes a free motion heat sink module that provides for mechanical reinforcement to the exciter connection to help resist shear forces while not impinging on the ability of the exciter to oscillate the panel in the desired fashion. The panel may also be provided with a flexible sleeve which allows for customization of the panel from an aesthetic point of view as well as for the alteration of specific tone production capabilities of the panel without the need to alter the panel construction or to disconnect the exciter or heat sink.

Abstract: A garment is provided which boasts the ability to simulate an authentic suit jacket, dress shirt, and/or tie for purposes of providing a professional appearance during a video conference call. The garment is configured to open from the back which is easily slipped on and securely attaches to the user's torso.

Abstract: An emergency call station provides emergency communication services for a user to contact an emergency responder. The call station includes an integrated IP video camera, an integrated security console, and at least one processor configured to provide network supervision status monitoring and notification, status message escalations, logging voice and video, text-to-speech conversion, multilevel forwarding, remote management of endpoints, pre-recorded messages, InformaCast® Compatibility; and mass emergency notification to multiple responders.

Abstract: A light weight fully assembled speaker enclosure is provided that includes a backbox having a peripheral edge; a grill that is crimped around the peripheral edge of the backbox, and a sound-baffle sheet disposed between the backbox and the grill, the sound-baffle sheet having an opening for placement of a speaker. Also provided is a speaker system having an audio speaker; a backbox having a peripheral edge; a grill that is crimped around the peripheral edge of the backbox and that is affixed to the speaker; and a sound-baffle sheet disposed between the backbox and the grill, the sound-baffle sheet having an opening for placement of the speaker.

Abstract: A housing for electronic apparatus, including an enclosure for housing power supply and amplifier circuits that are common to a number of different functional devices. A replaceable, hinged, modular front panel is provided and carries a control circuit on its inner face and switches, indicators, and control knobs on its outer face. Several front panels can be provided having different control circuits for connection with the power and amplifier circuits in the enclosure to thereby change the function of the device or the types of outputs and control functions that it can provide. The front panel is pivotable relative to the enclosure to permit quick and easy access to the interior of the enclosure for inspection and servicing, as well as ready accessibility to the control circuit that is mounted on the control panel. A metallic channel extends from the back panel to the control panel to provide a shielded wireway for input conductors connected with the control circuit.

Abstract: Logic circuits including electronic switching are provided for admitting or rejecting signals from a dual multi-frequency telephone into a trunk line, or toll line, the initiating control of which is provided from a dial tone signal feeding a detection circuit whereby selective recognition of coded signals permits further processing into the trunk line, there being additional, specific logic circuits for preventing further processing of the coded signals when a "zero" or a "one" numerical digit is recognized as the first signal. If the dial tone signal is not detected, the telephone line connected to a telephone is held at a voltage polarity which prevents dialed signals from the telephone from reaching the telephone line. When a dial tone is detected, the line polarity is reversed, thereby permitting dialed signals to reach the line.
