Abstract: A locking cylinder (1) with a cylindrical housing (2) of which the core bore (7) receives a cylindrical core (8) having a key channel (9) with core pins provided in the cylindrical core and housing pins displaceably guided in housing pin bores, the housing pins being resiliently biased by springs in the direction of the core pins, and with at least one additional, core-adjacent tumbler element (15) adjacent the wide-side profile of the key, the element (15) being displaceable in a cavity (H) crossing the rotational interface of the cylindrical core, the tumbler element being spring biased in the outward direction of the core and having a control projection (22, 51) projecting sidewards into the key channel (9, 43). In order to provide greater security, a locking recess (13', 48) is located in crossing or opposing relation to the housing pin bores, for receiving the additional tumbler element (15, 49) so as to block rotation, in which a housing-adjacent tumbler pin (14) biased in the inward direction of the core is able to project into the core cavity (13) when the tumbler pin (15) is withdrawn across the rotational interface (F), and in which the spring force of the spring (17) loading the additional tumbler element (15) is larger than that of the spring (18) which loads the housing-adjacent tumbler element (14).

Title: Aid for guiding blind person towards and around objects, comprises distance sensor connected and vibrating pads worn on back of hand
Inventor: PETERS PETRUS HUBERTUS
IPC: A61F9/08
Filed: 2005-08-02
Granted: 2007-01-22
Abstract: The aid comprises a distance sensor secured on top of an elastic band and designed to be worn on the back of one hand. Six vibrating pads next to the sensor are in contact with the skin on the back of the hand and vibrate from the wrist to the fingers with increasing frequency as the distance from an object gets smaller. A switch between the thumb and index finger is used to switch the aid on and off and to adjust the range of the sensor, which can be e.g. 0.5 or 1 m. A miniature camera can be secured to the band next to the sensor and the recorded image of the object is compared with images stored in a database on a palmtop computer and when a match is found the object is identified via an audible signal sent to an earpiece. An RFID reader can also be positioned next to the sensor in addition to or in place of the camera.
