Abstract: Modules that can be impinged upon by compressed air are arranged in front of and behind a box-shaped spar (1), whereby said modules have an airtight top skin and an airtight bottom skin and plates (7) which can transmit thrust are disposed therebetween. Each plate (7) has a console on each side. Said console extends along the entire length of the wing profile. One to two flexible tubes (9) that are airtight and only slightly extensible are inserted between two such consoles. When the tubes are subjected to pressure, they cause the plates (9) to move substantially parallel to each other and provide the wing with the desired camber. The aerodynamic profile is defined by rigid sheeting (10) whereby said sheeting (10) is secured to the top skin, bottom skin (5) and the sheet in an articulated manner by the plates (11) that are provided with. hinges (14). The on-flow edge (3) of the wing has two airtight and only slightly extensible flexible tubes (15,16) which, when inflated in an appropriate manner, provide the on-flow edge (3) with the required shape. The off-flow edge (4) is open.

Abstract: According to this invention, a digital key telephone system connected to an analog public network NW having a function of transmitting a ringing signal including identification information of a calling line through a subscriber line (CO line), accommodating a plurality of extension lines each connected to a digital key telephone (DKT) 2 or a standard telephone (STT) 4 as an extension terminal, and having a function of switching and connecting the subscriber line to the plurality of extension lines or the extension lines to each other includes a called party storage means storing, in advance, information representing the correlation between the calling line and the extension terminals 2 and 4 as a called terminal. When a ringing signal arrives from the analog communication network NW, calling line identification information (caller ID) contained in the ringing signal is detected by a calling line identification information interface unit (RCIU) 12. A control unit (RCTU) 16 determines the called extension terminal on the basis of the detected caller ID and the information stored in the storage means, so the extension terminal receives the call from the digital key telephone interface unit (RDKU) 13 or a standard telephone interface unit (RSTU) 15.

Abstract: Paging areas aligned with wireless terminals are dynamically created. A first base station passes to the wireless terminal a list of all the base stations that it knows and are within a prescribed number of handoffs of the first base station. The wireless terminal uses this list to define its own "personal" paging area. Each time the wireless terminal emerges from a sleep state, it listens for the base station having the best signal and compares its identification against the list of base stations in its personal paging area. If the best signal base station is on the list, any paging messages for the wireless terminal are automatically broadcast by that base station. Otherwise, the wireless terminal must conduct a handoff to that base station to obtain a new personal paging area centered on that base station with that base station as paging agent. Messages originating elsewhere in the network are forwarded to the paging agent for delivery to the wireless terminal. The paging agent then instructs all known base stations within prescribed number of handoffs of it to page the wireless terminal. The wireless terminal, on hearing the page, will form a connection with the base station having the best signal for communicating. The base station having the best signal for communicating notifies the paging agent that it has established a connection with the wireless terminal, which leaves paging mode and becomes active.

Inventor: LORD KEVIN M
IPC: A61M1/00
Filed: 2000-06-16
Granted: 2009-07-28
Abstract: Featured is a pressure control regulator including a housing, a sealing member disposed within the housing, a flexible member and a biasing mechanism. The housing includes at least one inlet aperture and at least one outlet aperture, each inlet aperture being fluidly coupled to a first pressure source and each outlet aperture being fluidly coupled to a second pressure source, the first and second pressure sources being at different pressures. The flexible member extends between the sealing member outside surface and the housing inner surface so as to form a pressure boundary therebetween and to divide the housing interior into first and second compartments. The biasing mechanism, being responsive to pressure within the second compartment, acts on the sealing member so the sealing member is in one of an open position, when the second compartment is greater than a predetermined pressure value, or a closed position, when the second compartment pressure is at or below the predetermined pressure value. A portion of the housing in fluid communication with the second pressure source, also includes a mechanism to restrict fluid flow to or from the second compartment such that the second compartment pressure changes when fluid flow in either direction occurs for a time more than a predetermined period of time and remains effectively unchanged when such fluid flow time is less than the predetermined period of time. In a more particular embodiment, the second pressure source is a suction source and the regulator is a suction pressure regulator.

Filed: 2002-07-16
Granted: 2010-05-11
Abstract: A screen is described wherein one end of the screen frame is provided with an upwardly open channel profile and the other end with a similar but downwardly open channel profile, such that the outboard edge of an upwardly open profile will fit within the channel of a downwardly open profile provided along the edge of an adjoining screen frame, to enable two such screens to be connected together and to enable linear movement in a direction generally perpendicular to the line of engagement and generally in the plane of at least one of the two screens, to be transmitted from one screen frame to the other. The engagement of one profile by another also serves to close the gap between the two screen frames and prevent at least particulate material from passing therebetween. Preferably the engagement prevents liquid from passing therebetween. The engagement may comprise a lost motion connection so as to permit one frame to be hingeable relative to the other about the connection, but still provides a reliable force-transmitting connection to enable a rear screen frame to be removed from the support structure simply by pulling out the front frame of the pair.
