A system for adjusting a deformable mirror including a reaction plate, a plurality of pneumatic actuators coupled to the reaction plate, and a plurality of push-pull flexures coupled on a first end to the pneumatic actuators, and coupled on a second end to the non-reflective side the deformable mirror, the plurality of push-pull flexures being disposed at various locations on the back of the deformable mirror. The respective pairs of push-pull flexures and pneumatic actuators are operated to support and alter the shape of the deformable mirror to allow for correction of a plurality of optical aberrations.

Pneumatic control system and method for shaping deformable mirrors in lithographic projection systems

A card edge connector comprising a housing, signal contacts and a ground contact. The housing has a card edge receiving area. The signal contacts are connected to the housing. The ground contact is connected to the housing and generally surrounds a corresponding signal contact.

High speed card edge connector with tubular shared ground contact

A card edge connector having a housing, first contacts, and second contacts. The first and second contacts each have mounting sections and cantilevered flexible sections. The mounting sections of the first and second contacts have different lengths. The cantilevered flexible sections of the first and second contacts have the same length and shape. The first and second contacts are inserted into the housing at the same time on a single carry strip to form multi-level contact areas.

Card edge connector with similar shaped cantilevered beam spring

A card edge connector having a housing, signal contacts and a four bladed ground contact. The housing has a card edge receiving area. The signal contacts are connected to the housing and the four bladed ground contact is also connected to the housing. The four bladed ground contact has a one piece frame with two pairs of opposing contact blades on opposite sides of the card edge receiving area in the housing.

An electrical connector is provided with a housing having a first member and a second member, electrical contacts, and retention members. The electrical contacts are fixedly connected to the first member and extend through the second member. The retention members fixedly connect the first and second housing members to each other and, include a mounting section for mounting the housing to a printed circuit board.

Multi-piece housing card edge connector with mounting arms

A daughter card is provided with an insertion portion, including a row of contact pads on each side of an edge prepared for insertion into the slot of card edge connector, and a contact structure extending from one or both sides of the card. Contact terminals of the contact structure extend parallel to the insertion portion of the card, being electrically connected to circuits within the card. On a mother board, a connector is provided with a first slot for removably receiving the insertion portion of the daughter card, and with one or two slots for removably receiving the contact terminals. The mother board and the daughter card include essential circuits, which are connected through the contact pads, and non-essential circuits, which are connected through the contact terminals. The daughter card may be plugged into a standard type of card edge connector, having only a single, central card-receiving slot, with the contact terminals extending outside the outer surfaces of the connector. A standard type of daughter card, with contact pads on an insertion portion but without the contact terminals extending outward from the card, can be plugged into the first slot of the connector.

High density interconnection system

An electronic connector is configured to removably receive either a circuit card of a first type, having one row of contacts per side, on an insertion tab adjacent to an insertion edge, or a circuit card of a second type, having two rows of contacts per side. Two rows of spring contacts are provided for this purpose on each side of a central card-receiving slot. Interposing means are also provided to prevent contact between a daughter card of the first type fully inserted in this slot and one of these rows on each side. These interposing means may consist of a slotted interposer structure slid over a portion of the insertion tab of the card, or alternately of a pair of pivotable interposers mounted along the length of the connector, to be pivoted by sections of daughter cards of the first type so that vanes extending from these interposers will push these springs away from the card. An electronic device, such as a connector of this type, includes solder tails for attachment within holes of a mother board, aligned in several parallel rows. Individual solder tails in each row are displaced by a first distance. Individual solder tails in adjacent rows are displaced by a second distance, which is a submultiple of the first distance less than half the first distance. This second distance may also be a multiple of the first distance divided by the number of rows.
