Title: A needle assembly having an elongate blunting device which allows for venting of air
Inventor: CHANG JOSEPH J
IPC: A61M5/158
Filed: 2000-11-30
Abstract: The invention generally relates to a needle assembly of the kind having a needle, an elongate blunting device, a shifting member, and a flash chamber. The needle is of the kind that has a needle proximal end, a sharp needle distal end and a needle canula extending therethrough. The elongate blunting device is at least partially located within the needle canula. The elongate blunting device is of the kind that has a blunting device proximal end, a blunting device distal end, and a blunting device blood flow passage therethrough, through which blood can flow from the blunting device distal end to the blunting device proximal end. The shifting member can be actuated to move relative to the needle and, upon movement relative to the needle, causes movement to the elongate blunting device from a retracted position wherein the blunting device distal end is retracted into the needle canula so that the sharp needle distal end can penetrate the body, to an extended position wherein the blunting device distal end extends out of the needle canula so as to prevent the sharp needle distal end from penetrating the body. The flash chamber is of the kind that has an internal volume which is in communication with the blunting device blood flow passage so that the blood can flow from the blunting device blood flow passage into the internal volume. The flash chamber is at least partially made of a material through which blood can be seen when located in the internal volume.

Title: Layout tool for laying out perpendicular lines
Inventor: BUTWIN ROBERT S
IPC: B43L7/10
Filed: 1998-09-04
Abstract: The instrument includes a pair of members (7, 8) arranged together to form an "L" at a right angle. The two opposing ends of the "L" are also affixed to another member (9) making the shape of a 3-4-5 triangle. All members of the instrument are permanently attached, therefore, misalignment is avoided and accuracy is assured and maintained. The two members are configured to slide with respect to one another at the pivot point of the "L" and simply pivot at their opposite ends about their pivot points connecting the third member and creating an enclosed triangle. A spring loaded rivet mounted in one of "L" members slides in a skewed slot (12) in the adjacent member to open the triangle from a closed position where the three sides of the triangle are substantially parallel to one another. The rivet locks in a semi-circular aperture which maintains the tool in a proper locking position.

IPC: E01F9/619
Filed: 1999-01-06
Abstract: A retroreflective sign (40) includes a rigid sign board (48) and a retroreflective sheeting (42) having a structured surface. The structured surface has cube corner elements (44a) formed therein, and is bonded to a surface (48a) of the sign board to define a plurality of cells. The cells protect the cube corner elements from moisture and dirt, which could adversely impact the retroreflective performance of the film. By sealing the structured surface directly to the sign board, rather than to an intermediate seal film and then to the sign board, a simpler prefabricated sign construction is achieved. In some embodiments, interconnected raised sections (44b) are used to define the seal cells. The raised sections can be incorporated into the structured surface of the retroreflective sheeting or into the surface of the sign board. Methods for making the disclosed sign boards are also disclosed.  The signs are used for traffic control purposes, street signs and vehicle license plates.

Title: Transceiver stacked assembly
Inventor: MA ZHENGXIANG
IPC: H01Q21/06
Filed: 2001-02-02
Abstract: A transceiver (100) comprises a stacked metal laminate assembly of a plurality of layers (104-112) inside an enclosure (102). A first layer (104) forms an antenna. A second layer (106) forms a ground plane for the antenna. A third layer (108) forms "front-end" filters (duplexer). A fourth layer (110) together with the second layer forms an electromagnetic isolation enclosure for the filters. A  fifth layer (112) comprises a PC board with electronic circuits of the transceiver mounted thereon, and is both mounted to and electronically shielded by the fourth layer. Each of the first through fourth layers is preferably made from a single metal layer, such as a sheet of metal, by stamping. Each of the first through fourth layers is either bent along its periphery into a substantially "cake-pan" shape, or is flat and has a separate side wall (130) attached thereto. Flanges (122 and 124) that are unitarily formed with the filters extend through orifices (126 and 128) in the second and fourth layers to connect the filters with the antenna and the electronic circuits. The connections may be conductive or capacitive. The assembly is put together by stacking the first through fourth layers and then epoxying, soldering, or welding them together.

Abstract: L'invention concerne un procédé permettant de mesurer le temps de transit d'impulsion d'un objet vivant. Pour produire un premier et un second signal d'onde d'impulsion, on détecte l'impulsion respectivement au niveau d'un premier et d'un second point espacés. On différencie le premier et le second signal d'onde d'impulsion et, en fonction des résultats, on choisit des points correspondants du premier et du second signal d'onde d'impulsion (par exemple, des points de pente maximale). On détermine le décalage de temps entre les points choisis, de façon à obtenir le temps de transit d'impulsion. De préférence, l'appareil selon l'invention mesure le temps de transit d'impulsion au moyen d'un capteur d'impulsions à fibres optiques comprenant une zone de couplage à fibres fondues pourvu d'au moins une partie pouvant infléchie sans mettre la zone de couplage sous tension.

Title: Device for measuring translation, rotation or velocity via light beam interference
Inventor: PARRIAUX OLIVIER M
IPC: G01D5/38
Filed: 1999-08-19
Abstract: The device for measuring translation, rotation or velocity includes at least a first grating (46) of period , and at least a second grating (48) of period /2, these first and second gratings being mobile relative to the other along a given direction of displacement. A light source supplies a beam (FI) incident upon the first grating (46) at an angle of incidence .alpha. which is not zero in a plane perpendicular to the grating lines, this angle of incidence being sufficient so that the light source and the detector are spatially separated from each other in projection on this plane and on the direction of displacement. The translation or rotation measurement is effected via interference of two beams (16, 18) originating from the diffraction of the incident beam (FI) into the "+1" and "-1" order followed by diffraction in the second grating (48) respectively into the "-1" and "+1" orders. In certain embodiments, the source and/or the detector are integrated in a semiconductor substrate. A particular arrangement of the device allows a bidirectional displacement measurement.
