In a probe card assembly, a series of probe elements can be arrayed on a silicon space transformer. The silicon space transformer can be fabricated with an array of primary contacts in a very tight pitch, comparable to the pitch of a semiconductor device. One preferred primary contact is a resilient spring contact. Conductive elements in the space transformer are routed to second contacts at a more relaxed pitch. In one preferred embodiment, the second contacts are suitable for directly attaching a ribbon cable, which in turn can be connected to provide selective connection to each primary contact. The silicon space transformer is mounted in a fixture that provides for resilient connection to a wafer or device to be tested. This fixture can be adjusted to planarize the primary contacts with the plane of a support probe card board.

An electric field proximity detector capable of detecting partially conductive or conductive objects regardless of their impedance to circuit ground. The detector has a sensor with a transmitting electrode, a receiving electrode, and at least one circuit ground electrode preferably arranged in a bulls-eye configuration with the ground electrode between the transmitter and receiver electrodes. With appropriate sizing, upon the approach of an object, a signal received by the receiving electrode decreases, at least until the object is within a threshold distance of the sensor. The size and positioning of the ground electrode further reduces the effects of stray capacitance.

A needle tip protective device for use with percutaneous entry needles. In one embodiment, the needle tip protective device includes a needle guard slidably mounted on a hypodermic needle, the latter having a needle tip located at the distal end thereof, and a change of profile formed medially there along. The needle guard is movable along the hypodermic needle and engageable with the change in profile formed thereon.

The present invention is directed to a shieldable blood collection set and a needle assembly for use therewith. The needle assembly includes a needle cannula having a puncture tip at a distal end, a hub which supports the needle cannula, and a shield. The hub and the shield are axially movable with respect to each other between a first sampling position, where the puncture tip is exposed from the shield, and a second shielded position where the shield covers the puncture tip. A gauze pad is connected to the shield through a tether. After a venipuncture procedure, the gauze is maintained over the needle puncture tip at the puncture site, and the needle is withdrawn from the patient by pulling on the hub. This movement causes the tether to tightly extend between the gauze and the shield, which causes the needle puncture tip to be withdrawn into the shield.

Moreover, excessive complex processes are not adopted for manufacturing the stealth fabric, and the stealth fabric can be produced by using a conventional fabric production method, so the stealthfabric is convenient for production and easy for implementation.

A circuit board area is formed on a front glass substrate of a liquid crystal display (LCD) panel, and driver ICs are mounted in the circuit board section. The driver ICs are electrically connected to an external display control device via a flexible printed circuit board (FPC).

The metal foil tape is also bonded to an external frame of an LCD device. As a result, the metal foil is electrically connected with the external frame and the radiating noises are effectively reduced.
