Title: A device for identification of the epidural space
Inventor: HASAN MANN
IPC: A61B17/34
Filed: 2000-07-05
Abstract: The device visually indicates when an epidural needle enters the epidural space. The device comprises a chamber 5 that may be cylindrical or cubic in shape, an elastic diaphragm 3 which may be made of rubber or synthetic fibre, a connection port 1 to connect an epidural needle and an injection port 2 incorporating a one-way valve through which either air or saline may be injected to pressurise the chamber 5. The pressure develops as the air or saline entering the chamber acts on the diaphragm 3 to make it bulge, the pressure is maintained by the one way valve until the tip of the epidural needle enters the epidural space. The diaphragm then visibly deflates as the air or saline is injected and the pressure is released.

Title: A method of delivering packets to a roaming mobile
Inventor: CHEN XIAOBAO X
IPC: H04L12/56
Filed: 2000-08-21
Abstract: To deliver packets to the Media Access Control (MAC) address of a roaming mobile 10 in a foreign network, a proxy Address Resolution Protocol (ARP) entity is set up and informed of a care of address (COA) and MAC for the mobile.

Title: Encoding and transmitting video data
Inventor: BOURNE DAVID RONALD
IPC: H04N21/434
Filed: 2001-01-19
Abstract: Fast and efficient transferral of video data is achieved by a method comprising segmenting a digital video image into at least a first and second segment. The intra coded frames included in the video stream are identified by an encoder, and the segments are encoded for the intra frames. The first segment is encoded at a first (low) quantisation level, and the second at a second (high) quantisation level. Both segments, encoded at different resolutions, may therefore be transmitted as a single signal. The first image segment provides a high resolution image for objects of interest, while fast transferral of the image as a whole is achieved as the second segment is encoded at a low resolution. Application of the method may include an alarm or security system where rapid transmission of an image is required as well as a high resolution image of the area of interest.

Title: Spread spectrum transmission system using power lines
Inventor: TAKADA HAJIME
IPC: H04L12/28
Filed: 2001-05-23
Abstract: An inexpensive spread spectrum transmission system prevents the infiltration of external noise and external leakage of spread spectrum signals. A plug socket (6) for terminal connection, into which is plugged the plug (7) for terminal connection of a spread spectrum communication terminal apparatus (3), is connected to an alternating current power supply line for communications (10), one end of which is equipped with an electrical plug (5a) which is plugged into the plug socket (104, fig 1) of a commercial electric power line (101, fig 1), via a blocking filter (4). The blocking filter prevents noise transmitted along the commercial electric power line from being transmitted to the spread spectrum communication terminal apparatus (3), and to maintain the secrecy of communications, preventing superimposed spread spectrum signals from the spread spectrum communication terminal apparatus being transmitted to the commercial electric power line. Since the alternating current power supply line for communications does not add large loads, it is possible to use an inexpensive, low-capacity blocking filter as the blocking filter.

Title: Thermal aircraft vent
Inventor: KAVANAGH PHILIP ROBERT
IPC: B64B1/62
Filed: 2000-10-09
Abstract: There are two ways to control the operation of vent valve (5) closing aperture (3) at the top of envelope (2) of hot air balloon (1). First control means normally extends valve panel (5) via a plurality of control lines (6) extending radially from its perimeter so as to close valve (5). This control means also includes a plurality of parachute shroud lines (18) conjoined at (19) to lines (6) at the perimeter of valve (5). Lines (18) join at central claw (20) from which control line (8) extends to the pilot for controlled slower release of gas during flight by lowering of valve (5) away from envelope (2). For rapid venting of gas, as may be needed on landing, the pilot pulls on line (7) of second control means. This leads to a plurality of control lines (13) attached to the underside of valve (5). Pulling on line (7) contracts or gathers valve (5) radially inwardly and downwardly to almost completely uncover aperture (3).
