A terminals (10) for use in connection of a first electrical interface (50) and a second interface (60), comprises a base portion (12) extending between the first electrical interface and the second electrical interface, a pair of arm portions (14) extending from two lateral sides of the base portion toward the first electrical interface, a solder portion (16) extending outwardly from the base portion (12) towards the second electrical interface, and at least one plate-like member disposed between the arm portion (14) and the solder portion (16) of the terminal (10).

An FPC connector comprises an insulative housing defining an FPC insertion slot, a plurality of terminals loaded within the insulative housing in parallel relationship, a metallic shell covering the insulative housing and an actuator pivotably provided on the insulative housing. Each terminal has a contact beam extending into the FPC insertion slot and at least terminal has a pivot beam formed with a pivot portion for the actuator. The actuator is formed with a shaft portion to pivotably engage with the pivot portion. A strengthening metallic sheet is insert-molded in the actuator, and electrically and mechanically connects with the metallic shell.

An electrical connector (1) includes an insulative housing (2) and a plurality of terminals (3) received in the housing. The housing has a front end with an opening for receiving an end of the FPC in engagement with contacting portions of the terminals, and a back end with a plurality of T-shaped protrusions (202), and a side end with two latching arms (21). An actuator (4) is pivotably mounted relative to the housing for floating movement between a first position allowing free insertion of the FPC into the opening and a second position biasing the FPC against the terminals. A shielding (5) is engaged with the back end and two latching arms of the housing for protecting the connector from Electro Magnetic Interference (EMI) during transferring signals between the FPC and the PCB by the connector. The shielding can also reinforce the strength of the housing.

A Flexible Printed Circuit (FPC) connector (1) includes a housing (2), a number of contacts (3,31) received in the housing, an actuator rotatably mounted on the housing, and a shielding (5) attached to the housing. The shielding substantially surrounds a top surface (201) of the housing. A number of securing slots (500) are defined in the shielding and engage with protrusions (202) of the housing for positioning the shielding on the housing. Grounding tabs (501) extend from the shielding for mating with corresponding grounding pads of a PCB. The shielding and the grounding tabs extending therefrom can provide EMI protection to the connector. The shielding can also reinforce the strength of the housing.

In a tire state quantity detecting apparatus, a detector that deforms by force exerted from a tire and that outputs a signal corresponding to the quantity of deformation is embedded within the tire. The detector is enclosed in a capsule within the tire, so that the quantity of deformation of the detector is reduced relative to the quantity of deformation of the tire.

A signal line, a power supply pattern and a ground layer are formed within a board. An outer via and an inner via are formed within the board. The outer via is connected to the signal line. The inner via is connected to the ground layer. The outer via serves as a signal line. The inner via serves as a ground. The signal line within a printed wiring board is connected to the outer via without interruption by a ground. The signal lines can spread within the printed wiring board in a complicated pattern as compared with a conventional pattern. Moreover, the impedance matching can reliably be established.

A dental handpiece for root canal treatment comprises an outer sleeve, a connecting device for connecting the handpiece to a control and analyzing unit, a measurement circuit having a power source and to a drive unit, an electrically conducting tool receptacle and an electrically conducting driving device, wherein the tool receptacle and the driving device are mechanically and electrically connected together so that a driving motion generated by the drive unit can be transmitted via the driving device to the tool receptacle and electrical measurement signals can be transmitted between the driving device and the tool receptacle. A first connection is provided for transmitting the driving motion. A second electrically conducting connection, which may comprise sliding contacts, is provided for transmitting the electrical measurement signals. With separate connections, an improved signal transmission and in particular a low loss of measurement signals of the root canal length measurement during the signal transmission are achieved.

A method of acquisition of a received signal received from a global navigation satellite system, includes: obtaining a snapshot of the received signal; correlating the snapshot with a locally-generated signal, wherein the correlating includes: trying a phase delay value indicative of a hypothesized phase delay of the locally-generated signal with respect to the snapshot; and obtaining a partition of the snapshot and the locally-generated signal into corresponding pluralities of blocks, and calculating partial correlation integrals for each block of the plurality of blocks. The corresponding pluralities of blocks each include a first block having a time duration related to the phase delay value.

An electrical connector (1) includes a dielectric housing (2), a number of power terminals (4) at one end of the housing, signal terminals (5) and solder pad contacts (6) disposed at the other end of the housing opposite to the power terminals. The housing includes a base portion (20) and a bottom portion (21) and defines a number of passageways (212, 213, 215) extending through the bottom portion. The terminals (4, 5) received in the passageways (212, 213) each have a contact portion (40, 50) and a solder foot (41, 51). The solder pad contacts and the power terminals have a width greater than the signal terminals. The solder pad contacts are upwardly inserted into the passageways (215) of the base portion from the bottom portion and each includes a retention portion (60) for interfering with the base portion and a solder foot (61) extending beyond the bottom portion. Use of wide power terminals and wide solder pad contacts at the other end of the housing provides balanced solder attachment to a pcb. The solder pad contacts are used solely for securement to the pcb.
