A structure of a structure release and a manufacturing method are provided. The structure and manufacturing method are adapted for an interference display cell. The structure of the interference display cell includes a first electrode, a second electrode and at least one supporter. The second electrode has at least one hole and is arranged about parallel with the first electrode. The supporter is located between the first electrode and the second electrode and a cavity is formed. In the release etch process of manufacturing the structure, an etchant can pass through the hole to etch a sacrificial layer between the first and the second electrodes to form the cavity; therefore, the time needed for the process becomes shorter.

Antimicrobial compositions and methods are disclosed. The antimicrobial compositions are particularly useful in providing antimicrobial capability to a wide-range of medical devices. In one aspect the invention relates a UV curable antimicrobial coating comprising a UV curable composition comprising an oligomer, a momoner, and a photoinitiator which are together capable of forming a UV curable polymer composition. The compositions include rheology modifiers as necessary. The compositions also include antimicrobial agents, which may be selected from a wide array of agents. Representative antimicrobial agents include cetyl pyridium chloride, cetrimide, alexidine, chlorexidine diacetate, benzalkonium chloride, and o-phthalaldehyde.

A semiconductor wafer is placed into a probe fixture with a front side of the wafer facing up. Power and signal probes are then placed on an integrated circuit (IC) formed on the front side of the wafer. The probe fixture is retained at a test station either in a upright or an inverted position for testing and optical failure analysis. The probe fixture includes a position adjustment mechanism to locate the entire probe above the wafer and to more precisely position a tip of the probe on the IC. Optical failure analysis techniques are performed on the front side or the back side of the wafer while the wafer is retained in the test fixture and the probes are connected to the IC.

The invention provides, in one embodiment, a multifunctional, multi-piece medical device and related method for providing access to an internal body cavity, such as for use with a vacuum lift shell. The device can include a cannula and a cannula extension. The device provides a conduit between the external environment and operative field inside the patient's body during medical procedures, including diagnostic, therapeutic and surgical procedures. The invention allows entry and exit of air or gas to help create and maintain the operative field. The invention can be used to provide an open and unobstructed working path, and allows the operative space to be maintained at ambient conditions of pressure and temperature.

A fastener for securing deck boards to a support structure without the need for driving screws or nails through the deck boards. The fastener includes two horizontal flanges that fit into slots cut into the sides of adjacent deck boards, a center hole for securing the fastener to the support structure and deformable, resilient elements that bridge the gap between adjacent deck boards during fastening yet compress inward when the boards swell and expand.

Methods and systems for defining and distributing information alerts include presenting a user with a series of templates that allows the user to define security events, information alerts to be triggered by the events, and intended recipients for the alerts. Intended recipients for the alerts are presented with templates that allow the individuals to input contact and schedule information for receiving the information alerts. A knowledge switch uses the event definitions and the contact and schedule information to detect events and distribute the information alerts to the intended recipients when an event occurs. The information alerts include directives that instruct intended recipients regarding action to be taken in response to a security event.

An implantable fluid management device, designed to drain excess fluid from a variety of locations in a living host into a second location within the host, such as the bladder of that host. The device may be used to treat ascites, chronic pericardial effusions, normopressure hydrocephalus, hydrocephalus, pulmonary edema, or any fluid collection within the body of a human, or a non-human mammal.

A stall detection circuit and method for a stepper motor. The circuit has an H-bridge configuration with an additional circuit pathway to ground being connected at a point between two center windings. During the transition between step sequences, the circuit employs a monitoring phase in which the previously active low side driver is turned off such that current passes through only the first winding and then is diverted to ground via the additional pathway. While the phase voltage is thus momentarily extinguished, the second coil is used to monitor the motor's back EMF, from which it can be determined whether the rotor is in a normal running mode, a stall, or a reverse condition.

A system and method for notifying an offline global computer network user of an online interaction in which the offline user could participate. The system and method specify notification criteria of the offline user, monitor activities occurring on the global computer network, compare the activities to the notification criteria, and, if the activities satisfy the notification criteria, forward an offline communication to the offline user, which notifies the offline user of the online interaction. Examples of the online interactions include chat rooms, game sites, instant messaging services, auctions, and calls made over the global computer network. Examples of the offline communication include calls to a wireline telephone, calls to a wireless telephone, messages to a caller identification device, messages to a wireless access protocol device, messages to a one-way pager, and messages to an interactive pager.

The invention relates to a Micro-LED (Micro-light emitting diode) array backlight source-based ink-jet printing quantum dot display device, which comprises a Micro-LED substrate, wherein a plurality of RGB (red, green and blue) pixel units arranged in an array are arranged on the Micro-LED substrate; each RGB pixel unit comprises a red quantum dot unit, a green quantum dot unit and a transparent unit; each red quantum dot unit comprises a Micro-LED chip and a red quantum dot material, and the red quantum dot material is excited by blue light emitted by the Micro-LED chip to emit red light; each green quantum dot unit comprises a Micro-LED chip and a green quantum dot material, and the green quantum dot material is excited by blue light emitted by the Micro-LED chip to emit green light; each transparent unit comprises a Micro-LED chip and a transparent material, and the transparent material is used for directly transmitting blue light emitted by the Micro-LED chip; a transparent material for packaging is arranged outside the RGB pixel units. According to the device, an ink-jet printing technology is adopted for film forming of quantum dots, so that the problems of complexity and low yield of an RGB tri-color process for manufacturing a Micro-LED full-color product are solved, and batch operation is realized.

A borided titanium article can include a titanium mass having titanium monoboride whiskers infiltrating inward from a surface of the titanium mass to form an integral surface hardened region. The titanium mass can be almost any titanium based metal or alloy such as high purity titanium, commercial grade titanium, α-titanium alloy, α+β titanium alloy, β-titanium alloy, titanium composite, and combinations thereof. Borided titanium articles can be formed by methods which include providing a titanium mass, contacting a surface of the titanium mass with a boron source medium, and heating the titanium mass and boron source medium to a temperature from about 700° C. to about 1600° C. The boron source medium can include a boron source and an activator selected to provide growth of titanium monoboride whiskers.
