The fingers catch behind the mounting device so that this is pulled off to drop into the container with the needle when the syringe is withdrawn from the tube.
Patent GB-0200343-D0 (GB)
Title: Illuminating surface
IPC: H05B37/02
Filed: 2002-01-08
Abstract: The present invention provides an illuminating surface, e.g. a floor or wall tile, that includes an array of identical circuits (G, K, H, L) that can each be connected to a power source/ 14 ). The surface emits light in the presence of an object touching or in close proximity to the surface. Each circuit includes a sensor ( 12 ), e.g. a pressure switch, for detecting the presence of the object; at least one light source ( 20 ) that is illuminated when the sensor of that circuit detects the presence of the object. The circuits control the illumination of the light sources ( 20 ) such that the light sources remains illuminated for a time after its associated sensor ( 12 ) has ceased to detect the presence of the object. Each of the circuits is connected with at least one adjacent circuit, and, when the sensor of the first-mentioned circuit detects the presence of an object, the light source(s) ( 20 ) of the adjacent circuits are illuminated, thereby causing an area of the surface to emit light that corresponds to and is larger than the shape of the object.

Title: Method and apparatus for robust local mobility management in a mobile network
IPC: H04L69/40
Filed: 2003-02-14
Abstract: A method and apparatus for robust mobility management in a network having a mobile node (MN), a mobility anchor point (MAP), a correspondent node (CN1, CN2), a home agent (HA) and an access router (AR1) and operating under a hierarchical protocol. The mobile node (MN) sends the address (102, 104) of the mobility anchor point (MAP) to the correspondent node (CN1, CN2) and sends the address (106, 108) of the mobile node (MN) on the network of the access router (AR) to the home agent (HA) and to the mobility anchor point (MAP). When failure of the mobility anchor point occurs, the mobile node recovers from the failure by selecting a new mobility anchor point or operating under a non-hierarchical protocol. Failure is detected by an intermediate router or by a correspondent node when messages fail to reach the mobility anchor point. The mobile node (MN) detects failure of the mobility anchor point when messages unexpectedly arrive via the home agent.
