The supported devices provide processing, storage, and communicating of the biosensor data captured. Integrated body motion generators generate power. In addition rapid acting zero insertion force mechanical and electrical connectors are provided for the interconnection of the biosensors, devices, and power sources.

An electrical apparatus in accordance with the present invention for electrically assembling a CPU to a printed circuit board. The CPU includes an array of pin legs. The apparatus comprises a base member securely assembled to the printed circuit board. A cover member is moveably assembled to the base member and defines an array of through holes for extension of the pin legs of the CPU. A driving arrangement is arranged between the base and cover member to drive the cover member to move between first and second positions. The arrangement includes a shaft having a helical section extending therealong, and a follower is moveable along the helical section when the shaft is rotated.

A normally closed connector apparatus for electrically connecting first and second circuit members. An electrically insulative connector housing having a first portion translatable relative to a second portion is provided. The connector housing is adapted to be positioned substantially between the first and second circuit members. A plurality of resilient contact members are retained in the first portion of the housing. The contact members have first distal ends that do not extend substantially above an upper surface of the second portion. Displacement of the second portion relative to the first portion in a translated configuration positions the first distal ends of the contact members above the upper surface of the second portion to electrically couple with the first circuit member.

The invention in one embodiment is a zero insertion force socket including a base; a cover engaged with the base to reciprocate in first and second directions; and a lever pivotably mounted to the base to move the cover in the first direction when the lever is pivoted laterally from a first position to a second position. In another embodiment, the invention is a printed circuit board assembly including a printed circuit board; a zero insertion force socket surface mounted to the printed circuit board; and a processor coupled to the zero insertion force socket.

In a socket system and method for coupling a pin of an IC (integrated circuit) device to a contact pad of a circuit board, a zif opening on a socket asserts substantially zero force as the pin of the IC device is inserted therein. In addition, a compression mount lead on the socket presses against the contact pad of the circuit board. Once inside the zif opening, the pin is coupled to the compression mount lead via forking leads that press against the pin. Thus, substantially zero force is applied on the body of the IC device. Furthermore, top portions of the forking leads contact a top portion of the pin toward the IC device to minimize an electrical path length.

A device for interfacing a test head and a prober is disclosed using wires or cables to provide the connection from a probe card interface boards to the probe card. The use of wires or cables, in place of the traditional pogo pin arrangement allows for more reliable and efficient testing, as well as additional high performance tests to be run. Optionally, a probe interface contains a stiffening member with multiple sidewalks and individual, configuration-specific probe card interface strips are connected to a probe card through zero insertion force clamps. The probe card interface attaches to the test head using standard probe interface board (“PIB”) docking mechanics. The assembly is then connected to a probe to carry out the testing procedures.

The invention relates to the technical field of avionics, in particular to a multi-channel ARINC (aeronautical radio incorporated) 700 bus monitoring device and a realizing method thereof. The device comprises an industrial personal computer, a bus adapter and bus access equipment, wherein a multi-channel ARINC 429 bus module is arranged in the industrial personal computer; the bus adapter comprises a main board, a self-checking module, a power supply management module and a switch matrix module; and the bus access equipment comprises an aviation bus distribution frame and a ZIF (zero insertion force) interface. Control data and bus data are switched between the industrial personal computer and the bus access equipment through the bus adapter; the industrial personal computer transmits an instruction package to the bus adapter to finish instruction loading through the ZIF interface; a monitoring circuit is mounted on an aviation bus, so that the bus data can be read; when other buses need to be monitored, by only updating the loading instruction, the switching of the channel can be finished, which is convenient and rapid; the speed requirements in an automatic measuring and monitoring system can be fully satisfied; the testing time is greatly reduced; and the problem of wasting a large amount of bus channels in a complex avionics system is solved.

An electrical connector is provided in the present invention, including an insulating housing, multiple power terminals and multiple signal terminals. The insulating housing has at least one upright power receptacle body and at least one upright signal plug body parallel to the power receptacle body. Wherein the power receptacle body forms an upright power port on a front surface thereof, and the signal plug body forms at least one signal port on a front surface thereof. Each power terminal has a plate-shaped base plate, at least one spring connection end and multiple tails. The power receptacle body and the signal plug body of the present invention are designed to be upright for saving the edge space of a circuit board. Moreover, the electrical connector of the present invention also has a character of zero insertion force by controlling the length of the signal terminal and the power terminal.

An electrical connector with upper contacts, for a flexible flat cable. The connector is an electrical connector for gripping a flexible flat cable by upper contacts, and the connector includes two kinds of contact members for gripping the flexible flat cable, a housing for receiving the contact members, and an opening/closing type actuator. The contacts of the two kinds of the contact members are spaced from each other in an insertion direction, and the contact members are alternately arranged in the housing so as to form staggered rows of the contacts. With a first kind of contact members, FPC can be inserted without insertion force, and with a second kind of contact members, the FPC can be inserted with low insertion force. The connector is characterized in that is has a zero insertion force (Z.I.F.) and low insertion force (L.I.F.) mechanism structure for insertion of the FPC, where the structure is constructed from the first contact members and second contact members.

The invention relates to a method for detecting a shielding layer of a capacitive touch screen. By use of a test computer with capacitive touch screen test software, a functional test board and a functional test adapter board, an FPC (Flexible Printed Circuit) shielding pin is simulated by a conductive material, so that the test of the shielding layer of a to-be-detected touch screen is achieved; the functional test board comprises a singlechip; the functional test adapter board is made of a bi-layer printed circuit board and used for line adaption; the functional test board is connected with the test computer by a USB (Universal Serial Bus) data line; the functional test board is connected with the functional test adapter board by a flat cable; the functional test adapter board is connected with the FPC of the to-be-detected touch screen by a ZIF (Zero Insertion Force) or BTB (Board To Board) connector; and the functional test adapter board is connected with the conductive material for simulating the FPC shielding pin by a flexible cable. The shielding pin of the flexible printed circuit board is stimulated by the conductive material for the test, so that the secondary damage of the FPC board in the detection process is avoided; and the method has high detection accuracy and efficiency, and strong operability.
