Abstract: A system and method for matching chip and package terminals and for packaging integrated circuits. Various aspects of the present invention may comprise receiving as input a first list of chip terminal identifiers and a second list of package terminal identifiers. The first and second lists may be analyzed with a first string-matching algorithm to determine a first set of matching pairs of chip terminals and package terminals. The first and second lists may also be analyzed with a second string-matching algorithm to determine a second set of matching pairs of chip terminals and package terminals. The first and second sets of matching pairs may be compared to identify common matching pairs between the first and second sets of matching pairs. An indication of the common matching pairs may then be output.

Abstract: A syringe needle device comprises a needle, a ring and a cover, wherein a needle seat of the needle can be engaged with the cover, a stopping portion is mounted on the needle seat for stopping the ring, thereby the needle is retained in the cover after taking out the ring and mounting on the cover.

Abstract: A backlight module for use in a planar display panel is disclosed. The backlight module comprises a lamp tube set, a light guide plate and a positioning body. The lamp tube set comprises a lamp housing and at least a lamp tube. An optical film is disposed on the light guide plate. The light guide plate has a side for insetting the light guide plate into the lamp tube set. Furthermore, the positioning body is disposed on an inner wall of the lamp housing and comprises at least a flange against the side. The light guide plate is positioned to contact the positioning body so as to form gaps between the at least a lamp tube and the light guide plate or between the optical film and the lamp housing.

Abstract: A seal includes an annular main member. A seal lip is projected inwards from the annular main member, wherein the seal lip has a tip and an outer inclined surface a plurality of helixes are projected from the outer inclined surface of the seal lip, each of which has a first extending section along a first direction and a second extending section along a second direction connected to the first extending section. The first extending section has a first free end and the second extending section has a second free end, and a junction of the first extending section and the second extending section is a turning point. A first angle is between each of the first directions and a corresponding tangent line of the tip, and a second angle is between each of the first direction and the second direction.

Abstract: A valveless micro impedance pump including a bottom layer, a middle layer, a top layer and a piezoelectric element. The middle layer and the top layer are sealed to form the water inlets/outlets, flow way, upper and lower vibration membranes and boss of the micropump. The piezoelectric element is fixed on the boss and the fixing seat. By means of the electric field effect, the upper and lower vibration membranes are pushed by the piezoelectric element through the boss. The medium within the flow way is squeezed to flow toward the water inlets/outlets on two sides. The upper and lower vibration membranes have different structures. Also, the hardness of the fixing seat is different from the hardness of the bottom layer. This leads to difference in impedance. Therefore, the wave of the medium can be transmitted.

Abstract: A fingerprint identification assembly includes a laminated lens having a first lens, a second lens and a third lens formed together with the first lens and the second lens, each of the first lens, the second lens and the third lens has a dielectric film coated thereon. At least one illuminator is located at a bottom of the laminated lens and a sensor located under the laminated lens for picking up an image of a fingerprint on top of the laminated lens. The dielectric film of the laminated lens allows light from the at least one illuminator to be partially reflected due to the fingerprint on the laminated lens and partially penetrates through the second lens and the third lens to be picked up by the sensor.

Abstract: The present invention relates to a microphone with dual effects for enhancing the physical acoustic volume and for acquiring uni-directional acoustic source. The microphone applies the viewfinder theory of the telescope. The sound source at a designated direction is past from the front end of a hollow tube through the tube such that the sound generates resonance and focusing effects when passing through the tube. The microphone provided at the end of the tube is allowed to increase the volume acquired without using a passive amplifying circuit. A high ratio of sound at the designated direction can also be acquired.

Abstract: A fingerprint identification assembly includes a body having an objective lens mounted on top of the body for receiving thereon a fingertip and a first reflective lens mounted on a bottom of the body to receive reflected light from the objective lens, a light source emitting light to the first reflective lens and a sensing device integrally formed with the body and having a second reflective lens to receive the reflected light from the first reflective lens and a sensor to receive the reflected light from the second reflective lens so as to compare the received reflected light with information stored inside the sensor.

Abstract: Wastewater is subjected to biological reaction in a bed containing the biological reaction bacteria on a particulate carrier wherein the lower portion of the bed is fluidized while the upper portion is maintained as a fixed bed. When the fixed bed portion becomes clogged with cellular material, the entire bed is fluidized and wash water is passed through the bed to remove excess cellular material. The method is applicable to advanced wastewater treatment, both secondary treatment for BOD removal, and tertiary treatment for nitrification and/or denitrification. The method is particularly advantageous for treatment of wastewater supplied at varying flow rates.

Abstract: Fine particulates are removed from fluids (gases or liquids) by beds of filter media operated as convertible (semifluidized) beds, wherein the fluidized portion of the bed progressively increases in size during the filtrations. The method has particular application to filtrations which are difficult to carry out by conventional filtrations methods.
